Jailkit is used to create a secure shell environment for the user. It's also used by ISPConfig to securely run user's cron jobs from command line. Default jailkit configuration may not properly support PHP. So, first jailkit needs to be installed:
$ sudo apt-get install jailkitThen configuration file /etc/jailkit/jk_init.ini needs to be modified by addding 2 new sections - php and env:
[php]
comment = the php interpreter and libraries
executables = /usr/bin/php, /usr/bin/php5.6, /usr/bin/php7.0, /usr/bin/php7.1, /usr/bin/php7.2, /usr/bin/php7.3, /usr/bin/php7.4, /usr/bin/php8.0, /usr/bin/php8.1, /usr/bin/php8.2
directories = /usr/lib/php, /usr/share/php, /usr/share/php*, /etc/php, /usr/share/php-geshi, /usr/share/zoneinfo, /usr/share/ca-certificates, /etc/ssl/certs, /usr/lib/ssl/certs
includesections = env, netbasics
[env]
comment = environment variables
executables = /usr/bin/envNotes:
- In the example above we have a system with multiple PHP versions installed from 5.6 till 8.2. Only those versions should be specified that are installed in the system and should be available inside the jailkit.
- Zone info data is copied in jailkit to avoid PHP error:
Timezone database is corrupt
- Certificates are copied to jailkit to avoid SSL error:
cURL error 60: SSL certificate: unable to get local issuer certificate
The php section should be added in the ISPConfig jailkit configuration:
The path of executable file should be relative to the user's home directory, for example, /private/import.sh:
To run a PHP file it can be specified like this:
php /web/administrator/cron.php
If you have absolute file paths specified in your project (such as Joomla) and that works fine during web access, then you may experience path resolution issue when running your code in console inside jailkit. The reason is that in jailkit you will have a different file structure and your absolute path won't work.
