History

Since Jordan Russell wasn’t satisfied with InstallShield Express which he had received upon purchase of Borland Delphi, he decided to make his own installer.[citation needed] At first, Inno Setup was little known. The first public version was 1.09.[citation needed].

To make an installation package with version 1.09, an “ISS.TXT” file needed to be created in the installation directory. In the file, the user needed to supply variables and values which are still used in Inno Setup today. These variables served as the configuration of the installation package but many other features could not be changed. The installation compiler had no editor and was more of a shell to compile scripts.

Throughout Inno Setup’s development, it was becoming more widely used. Since Inno Setup was and still is free and open source, many software companies started switching to the open source solution in software installation[citation needed]. Since Inno Setup was based around scripting, fans of Inno Setup started ISTool and ScriptMaker to aid in visual and simpler ways to make installations for Inno Setup.

Inno Setup has won many awards including the Shareware Industry Awards three times in a row – from 2002 to 2004.

Many people have taken Inno Setup source code and used it to develop third-party versions of Inno Setup. An example is My Inno Setup Extensions by Martijn Laan. In June 2003 My Inno Setup Extensions was incorporated into Inno Setup.

Features

* Support for all modern versions of Microsoft Windows – 95, NT 4.0, 98, 2000, Me, XP, Server 2003, XP 64-bit, XP Professional and Vista. (No service packs are required.)
* Extensive support for installation of 64-bit applications on the 64-bit editions of Windows XP and Windows Server 2003. Both the x64 and Itanium architectures are supported.
* Prior versions supported Windows NT 3.51 (Before v3.0) and Windows 3.X (Before v1.3)
* Supports creation of a single EXE to install programs for easy online distribution.
* Supports disk spanning.
* Customizable setup types, e.g. Full, Minimal, Custom.
* Complete uninstall capabilities.
* Integrated support for “deflate”, bzip2, and 7-Zip LZMA file compression. The installer has the ability to compare file version info, replace in-use files, use shared file counting, register DLL/OCXs and type libraries, and install fonts.
* Creation of shortcuts, including in the Start Menu and on the desktop.
* Creation of registry and .INI entries.
* Integrated Pascal scripting engine.
* Support for multilingual installs.
* Support for passworded and encrypted installs.
* Silent install and uninstall.
* Full source code is available (Borland Delphi 2.0-5.0).
* Supports Unicode and right-to-left languages.

Missing features

* Does not support Modify/Repair type operations.
* Does not support Vista Administrator Elevation on demand (only when required for installation directory or registry manipulation).

Inno Setup is an open source script-driven installation system created in Delphi by Jordan Russell.

Inno Setup at Wikipedia

The Inno Setup Extensions Knowledge Base (ISXKB) aims to support users of this installation system by providing a source of information, code snippets, guide lines, and ready-to-use solutions.

There are currently 147 articles in the ISXKB. You can search the ISXKB, browse through a list with all articles, or view them sorted by category. A list sorted by article popularity is also available as well as all special pages.

If you would like to help improve and extend the ISXKB Help:Editing_pages is the place to go. Note that because of spamming now only trusted users can change and add pages, but it’s easy to become one (if you’re not a spammer ;-). Help:Editing_pages explains how.

If you are a developer and you’re using Inno Setup as your deployment application feel free to add your software to the subcategory it belongs to under the Inno Setup users category, or create a subcategory if you think it doesn’t fit anywhere else.

I need to define a set of variables to manage ftp connection.

[Setup]
AppName=My Program
AppVerName=My Program version 1.5
DefaultDirName={pf}\My Program
DefaultGroupName=My Program
FtpUSER=
FtpPassword=
FtpHost=

The user can value this variables and this values need to start ftp.

How can I do it?

Distributed Setup Development Can Work

Back in 2005 I was involved in a distributed setup development environment that was a complete disaster. The combination of vdproj/installutil and poor software architecture choices had resulted in me being very jaded against the notion of sharing responsibility of developing setup with the developers. Unfortunately, the model of centralized setup development can only scale so far before the quality of the installer declines not because the setup developers don’t know how to write good setup but because they just can’t keep up with the sheer size of the application domain. They simply don’t know enough to be able to help make good decisions. Eventually this becomes just as fatal as the very model that first jaded me into not sharing any responsibility.

In 2009 I found myself at this breaking point and decided to once again try setup democratization. This time, I wanted to find just the right blend between centralized and decentralized. I believe with WiX, InstallShield and a little out of the box thinking we’ve succeeded in doing just this and that we will be able to scale for many more years to come.

Visualization

One of the biggest problems developers had was they couldn’t easily see into the structure of an installer or compare the installer to previous builds or other installers. Sure, I could try to teach them to use orca, perform administrative installs or do other tricks but what they really needed was a powerful “Google Earth” style tool that really lets them drill down through and search across to get situational awareness. Once they had this capability they could make better choices.

Simplification

Application developers don’t have 6 months of free time to learn the Windows Installer . They need to be provided a short training session with an important set of rules to not break. The component rules can be basically explained by quoting The Highlander Movies: ‘There can only be one.’ Tell them that MSI is a declarative not imperative language. Relate it to things they understand like WPF and XAML. Explain to them to not ask for things like xcopy, regsvr32, regasm, gacutil or installutil. Instead ask them to ask for things at a higher level such as register a (un)managed file, deploy a file to the GAC or install/start a service. Finally provide tools that allow them to self-serve the majority of the heavy lifting: Files and Folders. Provide a tool that is simple to use yet still creates XML documents that follow the component rules and allow for adding in additional metadata by the setup experts. Finally, invest in making strong relationship with the developers. The setup developers will find themselves with more free time to go around and consult with the developers to help bridge the gap between application domain knowledge and setup domain knowledge. Both sides will gradually learn more about the other.

Validation

Entropy applies to setup. The best way to preserve the order that you fight so hard to create is to perform extensive validation with each build. Don’t allow one mistake to build upon another. Fail the builds and get your problems fixed ASAP. Make the mistake bubble up to the developer in a way he will understand and know to not repeat.

WiX and InstallShield can Complement Each Other

Usually one thinks about WiX *VS* InstallShield. I now no longer see it this way. I now see it as WiX *AND* InstallShield. Each tool has strengths and weaknesses but blended together result in a very powerful platform. However, I do believe that is time for a fully functional InstallShield style IDE to be built upon the WiX schema. I openly hope that InstallShield will take this challenge. Until then I will be building IsWiX and I hope others will either join me.

Setting up the cron jobs in Jenkins using “Build periodically” – scheduling the jenins Job

Examples –
To schedule your build every 5 minutes, this will do the job : */5 * * * * OR H/5 * * * *

To the job every 5min past every hour(5th Minute of every Hour) 5 * * * *

To schedule your build every day at 8h00, this will do the job : 0 8 * * *

To schedule your build for 4, 6, 8, and 10 o’clock PM every day – 0 16,18,20,22 * * *

To schedule your build at 6:00PM and 1 AM every day – 0 1,18 * * *

To schedule your build start daily at morning – 03 09 * * 1-5

To schedule your build start daily at lunchtime – 00 12 * * 1-5

To schedule your build start daily in the afternoon – 00 14 * * 1-5

To schedule your build start daily in the late afternoon – 00 16 * * 1-5

To schedule your build start at midnight – 59 23 * * 1-5 OR @midnight

To run a job on 9.30p.m. (at night) on 3rd of May then I ll write or 21.30 on 3/5/2011 – 21 30 3 5 *

Every fifteen minutes (perhaps at :07, :22, :37, :52) 0 – H/15 * * * *

CRON expression

A CRON expression is a string comprising five or six fields separated by white space that represents a set of times, normally as a schedule to execute some routine.

Format

In some uses of the CRON format there is also a seconds field at the beginning of the pattern. In that case, the CRON expression is a string comprising 6 or 7 fields.

Special characters

Support for each special character depends on specific distributions and versions of cron
Asterisk ( * )
The asterisk indicates that the cron expression matches for all values of the field. E.g., using an asterisk in the 4th field (month) indicates every month.
Slash ( / )
Slashes describe increments of ranges. For example 3-59/15 in the 1st field (minutes) indicate the third minute of the hour and every 15 minutes thereafter. The form “*/…” is equivalent to the form “first-last/…”, that is, an increment over the largest possible range of the field.
Comma ( , )
Commas are used to separate items of a list. For example, using “MON,WED,FRI” in the 5th field (day of week) means Mondays, Wednesdays and Fridays.
Hyphen ( – )
Hyphens define ranges. For example, 2000-2010 indicates every year between 2000 and 2010 AD, inclusive.
Percent ( % )
Percent-signs (%) in the command, unless escaped with backslash (\), are changed into newline characters, and all data after the first % are sent to the command as standard input.[7]

Non-Standard Characters

The following are non-standard characters and exist only in some cron implementations, such as Quartz java scheduler.
L – ‘L’ stands for “last”. When used in the day-of-week field, it allows you to specify constructs such as “the last Friday” (“5L”) of a given month. In the day-of-month field, it specifies the last day of the month.
W – The ‘W’ character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify “15W” as the value for the day-of-month field, the meaning is: “the nearest weekday to the 15th of the month.” So, if the 15th is a Saturday, the trigger fires on Friday the 14th. If the 15th is a Sunday, the trigger fires on Monday the 16th. If the 15th is a Tuesday, then it fires on Tuesday the 15th. However if you specify “1W” as the value for day-of-month, and the 1st is a Saturday, the trigger fires on Monday the 3rd, as it does not ‘jump’ over the boundary of a month’s days. The ‘W’ character can be specified only when the day-of-month is a single day, not a range or list of days.
Hash ( # )
‘#’ is allowed for the day-of-week field, and must be followed by a number between one and five. It allows you to specify constructs such as “the second Friday” of a given month.[8]
Question mark ( ? )
In some implementations, used instead of ‘*’ for leaving either day-of-month or day-of-week blank. Other cron implementations substitute “?” with the start-up time of the cron daemon, so that ? ? * * * * would be updated to 25 8 * * * * if cron started-up on 8:25am, and would run at time every day until restarted again.

In addition, @yearly, @annually, @monthly, @weekly, @daily, @midnight, and @hourly are supported as convenient aliases. These use the hash system for automatic balancing. For example, @hourly is the same as H * * * * and could mean at any time during the hour. @midnight actually means some time between 12:00 AM and 2:59 AM.

After a quick detour to install Notepad++, I’m on my way to installing Magento. Before I can get into the meat of it, though, I do require a few prerequisites.

From the installation instructions, installing Magento requires:

• Apache 1.3.x or Apache 2
• PHP 5.2.0 and above with Safe mode off
• MySQL 4.1.20 and above

After a brief search, I happened upon a very handy site (Yes, my current dev machine runs Windows 7). No sense reinventing the wheel, so these instructions should do nicely.

I’ve chosen the latest stable release, 2.2.17, MD5-verified and ready to install.

Always one to put the right foot forward… The first thing I’ve done is to immediately download the wrong version (src) instead of the neatly prepped installer (msi) as per the instructions. Round 1 goes to my eagerness, but after a neat revisit to the Apache download page, I’m off in the right direction.

After kicking off the Apache installer, my first instinct was to twitch at the frozen installer progress (Did the instructions forget about that ghastly Windows 7 User Account Control?), but after only a brief pause, the UAC prompt has displayed and the Apache web server installation is back on track.

None the worse for wear, time for the next step.

PHP

I’ve pretty much kaboshed most of the PHP installation instructions, mostly due to its avoidance of the handy PHP for Windows installer. Pointing the installer to the Apache web server’s cgi-bin folder seems like a good idea.

A configuration change…

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = “./”
; On windows:
extension_dir = “ext” ; Uncommented (removed the semicolon at the beginning of) this line

… and I’m back to the instructions. After an update to my environment variables, looks like it’s time for a reboot… and sleep.

I’ll be leaving the MySQL install (and testing Apache web server and PHP) ’til tomorrow.

The post Apache web server Installation Guide, know how to Install Apache web server on Windows 7? appeared first on scmGalaxy.

The tasks can be scheduled to run on the same machine (Master), or on a different machine (Slave). A master is a installation of Hudson, that can manage one or more slaves. The role of master remains same in Master slave setup. It serves HTTP requests, and it can still build projects on it’s own.

Slaves are computers that are setup to build projects triggered from the master. A separate program called slave agent runs on slave computer. In this article we’ll discuss about how to setup Hudson to executed distributed builds using Master slave. One computer can be configured to execute multiple slave agents.

How it works

When the slaves are registered to a master, the master starts distributing loads to slaves. The delegation depends on the specific job. The job can be configured to either execute on the master, or it can be tied to a specific slave. On the other hand, the jobs can be configured to freely roam between slaves, wherein the job is executed using the free slave. As per the user is concerned, the setup is transparent. The results for all jobs are viewable using the Master, irrespective of the Slave that executed the job.

The slave may be built using any Operating system. The Master slave setup is highly helpful while the user has to execute the job on different Operating system. Consider this use case: The application is expected to run on different operating system, Linux, Solaris and Windows system. To address this need, the user can install Hudson on any machine, say Linux, and add 2 slaves: Solaris and Windows. The user can add 3 different jobs, one running on Master itself and others running on slave machines.

Methods to set up Slave agents

The slave can be launched from Master using any of below methods:

1. Launch Slave agents on Unix machines via SSH.
2. Launch Slave agents via JNLP.
3. Launch Slave agents via execution of command on the master.
4. Let Hudson control windows slave as a windows service.

The following screenshot illustrates the list of modes under which the Hudson slave can be launched.

Set up Slave agents on Unix machines via SSH

Hudson has a built-in SSH client implementation that it can use to talk to remote sshd and start a slave agent. This is the most convenient and preferred method for Unix slaves, which normally has sshd out-of-the-box. Click Manage Hudson, then Manage Nodes, then click New Node. In this set up, the connection information is supplied, including SSH host name, user name and authentication credentials. The authentication is performed using password or ssh keys. If it is configured to use ssh keys, the SSH public key should be copied to ~/.ssh/authorized_keys file. Hudson will do the rest of the work by itself, including copying the binary needed for a slave agent, and starting/stopping slaves.

 

Depending on the project and hardware resource availability, the user Desktop can be used as one of Slave, without affecting his day-to-day activities, thus avoiding the need for dedicated Slaves.

Establish slave agent via Java Web Start

Another way of launching slave is to start a slave agent through Java Web Start (JNLP). In this approach, the user will login to the slave node, open a browser and open the slave page using the URL pointed to the Master. It may look like the following URL:

http://masterserver:port/hudson/jnlpJars/slave.jar

The user is presented with the JNLP launch icon. If user click the icon, the Java Web Start kicks in and it launches a slave agent on this computer.

This mode is convenient when the master cannot initiate a connection to slaves, such as when it runs outside a firewall while the rest of the slaves are in the firewall. The disadvantage is, if the machine with a slave agent goes down, the master has no way of re-launching it on its own.

Set up slave agent headlessly

This launch mode uses a mechanism very similar to Java Web Start, except that it runs without using GUI, making it convenient for an execution as a daemon on Unix. To do this, the user should configure this slave to be a JNLP slave by downloading slave.jar, and then from the slave, run a command like this:

java -jar slave.jar -jnlpUrl http://yourserver:port/computer/slave-name/slave-agent.jnlp

The slave.jar file is downloaded from the above mentioned URL. Make sure to replace slave-name with the name of the slave setup in Master.

By default, Hudson runs on port 8080. It can be installed and managed without the need for super user privilege. The super user privilege is not required to manage both Master and Slave.

The below diagram illustrates the list of configuration parameters specific to a slave.

 

set up Slave Agent using own scripts

If the above modes is not flexible, the user can write his own script to launch the Slave agent. The script is placed in the Master computer and Hudson runs this script whenever it should connect to the slave. The script may use the remote login program like SSH, RSH to establish connection between Master and slave.

The script would execute the slave agent program like java -jar slave.jar. The stdin and stdout for the script should be connected to the master. For example, the script that does ssh myslave java -jar ~/bin/slave.jar would satisfy this need, when it is executed from the Master web interface. For this reason, running this script manually from the command line does no good.

The copy of slave.jar can be downloaded from the above mentioned URL. Launching the slave agent using this mode requires additional setup in the Slave. The benefit is that when the connection goes bad, the user can use Hudson web interface to re-establish the connection.
