Firewall Services (original contrib)
This contrib allows you to install PHP version 5 alongside PHP version 4, which is the default in SME Server 7.x. Unlike a full upgrade to PHP5, installation of this contrib will not affect your ability to install future updates to SME Server 7.x. PHP 4 remains the default version.
To install the contrib, issue the following command from the console:
yum --enablerepo=smecontribs install smeserver-php5-cgi signal-event post-upgrade ; signal-event reboot
To upgrade from Firewall Services' earlier release, you must do as follows:
1. Delete ALL custom templates created while following the earlier Firewall Services howto.
2. Install the updated contrib as above.
3. Follow the instructions below to enable PHP5 for your web applications.
PHP5 can be used in Ibays and for contribs that are installed in /opt.
To configure an Ibay to use PHP 5, run the following commands from the shell:
db accounts setprop [ibayname] php5 yes signal-event ibay-modify [ibayname]
To return to the default version of PHP, run the following command from the shell:
db accounts setprop [ibayname] php5 no signal-event ibay-modify [ibayname]
Web applications that are installed in /opt can also be configured to use PHP5. Ideally, application packagers should update their integration RPMs to depend on smeserver-php5-cgi and deploy a new template fragment, but if you wish, you can also configure PHP5 manually.Here are two shell scripts that will switch between PHP v4 and v5.
First, create a custom template:
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/ pico /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/90[MyAppName]
Next, put the following lines in the new file:
<Directory /opt/[myapp]> AddHandler php5-cgi .php Action php5-cgi /php5-cgi/php-cgi </Directory>
Save and exit (CTRL-O, CTRL-X), and then expand the web server's configuration template:
Before you apply the changes, be sure to check that there is no error in the new configuration file:
If this command returns ’Syntax OK’, you can restart the web server:
svc -t /service/httpd-e-smith
You can fine-tune PHP5 using the e-smith configuration database. To keep things simple, PHP5 inherits the same settings as PHP4. To modify a property, issue the following commands from the SME Server shell:
db configuration setprop php [property] [value] expand-template /etc/php5/php.ini
Note that any changes will also affect PHP4. To apply the changes to PHP4 immediately, run:
