Customizing Platform Templates

Non-standard Aegir installs may require adjustments to the default configurations for a platform that are defined by Aegir during the creation of a platform. These templates can be found in /home/aegir/.drush/provision.

Editing the actual templates prevents Aegir from overwriting your customizations when the verify task is run on an live platform.

Below are examples of customizations made to non-standard Aegir installs

Running an Aegir platform on a unix socket for php-fpm on Nginx

First let's find out where provision has the default config templates for our platfom.

[root@host]cd /home/aegir/.drush; grep -nir "fastcgi_pass" --exclude=*.svn* *
provision/http/nginx/nginx_advanced_include.conf:227:        fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_advanced_include.conf:360:          fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_simple_include.conf:213:        fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_simple_include.conf:346:          fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
We can see that the config templates for Nginx direct all php requests to port 9000 on the localhost I.P. Let's change that to a unix socket (which avoids the slight delay associated with tcp connections). After commenting out those lines and adding our custom lines which will use a unix socket instead of a tcp port, we get..
provision/http/nginx/nginx_advanced_include.conf:227:    #    fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_advanced_include.conf:228:        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
provision/http/nginx/nginx_advanced_include.conf:361:          #fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_advanced_include.conf:362:          fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
provision/http/nginx/nginx_simple_include.conf:213:        #fastcgi_pass   127.0.0.1:9000; ### php-fpm listening on port 9000
provision/http/nginx/nginx_simple_include.conf:214: fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
provision/http/nginx/nginx_simple_include.conf:347:#          fastcgi_pass   127.0.0.1:9000; ### php-fpm lis#tening on port 9000
provision/http/nginx/nginx_simple_include.conf:348:     fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

Remember to do the same to your platform config files in /home/aegir/config/includes. Next time you verify your platform your customizations will remain after verification.
