Examples

Redirect to a specific page during the deployment process and modification of the content of some file

In this example with two very simple shell scripts I automatize some little tasks before and after the deployemnt process.

Before the deployment (exactly between the export of files from Subverseion and the synchronisation with production files)

  1. I change the .htaccess of my project to redirect the visitor to a specific page during the deployment process.
  2. I modify the value of a constant in a configuration file as needed on the production server.
  3. I move some temporaries "302.*" files to redirect my visitors on.

Files in .fredistrano directory in my project

At the root of my project to deploy, I have created a specific folder contening some files :

.htaccess <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !302\..*$ RewriteRule (.*) /myProject/302.html [L,R] </IfModule>

302.html ``` Application in maintenance

</head>
<body>
    <h1>Application in maintenance</h1>
    This application is in maintenance for very short time.<br>
    <a href="http://mydomain.com/myProject/">Please try again in few minutes.</a>
    <img src="302.png" alt="maintenance" title="maintenance" style="float:center;" />
</body>

```

beforeScript ```

!/bin/sh

PATHPRD=/cygdrive/d/www/html/myProject PATHTMP=/cygdrive/d/www/html/fredistrano.1.0.RC1/files/tmp/myProject/tmpDir

move the specific temporary .htaccess at the right place

cp -vf ${PATHTMP}/.fredistrano/.htaccess ${PATHPRD}/.htaccess

move the specific temporary redirect page at the right place

cp -vf ${PATHTMP}/.fredistrano/302.* ${PATHPRD}/ ```

afterScript ```

!/bin/sh

PATHPRD=/cygdrive/d/www/html/myProject PATHTMP=/cygdrive/d/www/html/fredistrano.1.0.RC1/files/tmp/myProject/tmpDir

sed -i.bak "s/('debug',)[ ]*[12]/\1 0/gi" ${PATHPRD}/app/config/core.php

replace the temporary .htaccess

cp -vf ${PATHTMP}/.htaccess ${PATHPRD}/.htaccess

remove the temorary redirection page

rm -vf ${PATHPRD}/302.*

remove the old version of app/config/core.bak

rm -vf ${PATHPRD}/app/config/core.php.bak ```
