TIL - Run multiple php-fpm instances on centos

Working as an Infrastructure Engineer, I have to deal a lot with migration tasks. One of my most paintful experience is to using multiple versions of php on the same server. Here is my notes when installing multiple php-fpm on the same servers
For example when I install php-fpm-7.2 and php-fpm-7.1 on the same server, I always get this error when starting the two processes:
$ sudo /etc/init.d/php-fpm-7.2 start $ sudo /etc/init.d/php-fpm-7.1 start
When running these two commands, I always got php-fpm-7.1 started, not php-fpm-7.2, so what is the problem ?
Because these two processes used the same configurations file in
/etc/php-fpm.conf so whether we started
php-fpm-7.2, only one processes get called.
So what can you do in this situation ?
- Rename the file in
/etc/php-fpm.confto something else
- Enable custom config file in
/etc/sysconfig/php-fpm-7.2. Below is the file's content :
1 # Additional environment file for php-fpm 2 # Uncomment below to use the php 7.2 specific configuration file 3 OPTIONS="-y /etc/php-fpm-7.2.conf"
Just uncomment the third line, then everything is OK.
