Record the process of an installation
System: centos
php version: 5.4 5.6
Purpose: Install two php versions
1: First install the first version of php5.4 via lnmp specific command lnum has specific operations on the official network
2: Modify the configuration of php-fpm
Stop running php-fpm first, check pid of php-fpm first

Look at the command: PS aux | grep php-fpm output shows that the current php-fpm runs a pid of 25903, then closes the current process first by ending the command.
End command kill-INT 25903:
After running, review the process again
[root@iZwz99zpj9k5noj0vtkozjZ etc]# ps aux | grep php-fpm
root 26059 0.0 0.0 112648 972 pts/0 R+ 13:54 0:00 grep --color=auto php-fpmPhp-fpm is indeed turned off.Then we found the configuration file location for php-fpm and started configuring php-fpm under 1.The results after configuration are as follows
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log //Modified Places
log_level = notice

listen.backlog = -1

pm.max_spare_servers = 20
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/php_5.4_slow.log //Modified Places
After the modification, it's time to restart fpm, but I changed the name of the profile above to distinguish between the two versions of php-fpm.conf and moved it under / usr/local/etc for easy administration.If you install PHP through lnmp, LNMP may have already helped you install php-fpm as a service, so that you can make php-fpm read a new configuration file by default by simply modifying the service's configuration file, which is located in
/etc/rc.d/init.d/php-fpm
prefix=/usr/local/php
exec_prefix=${prefix}
conf=/usr/local/etc //Newly added
php_fpm_BIN=${exec_prefix}/sbin/php-fpm
php_fpm_CONF=${conf}/php-fpm-5.4.conf //modify
php_fpm_PID=${prefix}/var/run/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"
After that, in order to distinguish the two PHP versions, I changed the name of this file to php-fpm-5.4. Okay, now let's start a new php-fpm, using the command service php-fpm-5.4 start
[root@iZwz99zpj9k5noj0vtkozjZ init.d]# service php-fpm-5.4 start
Starting php-fpm done

After startup, we checked the next process, it seems that the startup was successful, but at this time when we visit the php file, we will find that the error reported is 502. This is because we changed the port of fpm from the default 9000 to 9001, but nginx reads 9000. Of course, this will happen in 502. Now we will modify the configuration of nginx to 9001 to see if it can be changed to 9001.Meritorious access.

If the configuration is okay, you can see the phpinfo information
3: Install another version of php, here I want to install the php5.6 version, directly download the code from the official website to install, specific installation
4: Once installed, we need to create another service to configure version 5.6 of php-fpm, copy a copy of the 5.4 service and rename it php-fpm-5.6 with the command cp/etc/rc.d/init.d/php-fpm-5.4/etc/rc.d/init.d/php-fpm-5.6, and then modify the file configuration inside
prefix=/usr/local/php5.6
exec_prefix=${prefix}
conf=/usr/local/etc
php_fpm_BIN=${exec_prefix}/sbin/php-fpm
php_fpm_CONF=${conf}/php-fpm-5.6.conf
php_fpm_PID=${prefix}/var/run/php-fpm.pid
Then copy a copy of the fpm configuration file command as
[root@iZwz99zpj9k5noj0vtkozjZ init.d]# cd /usr/local/etc
[root@iZwz99zpj9k5noj0vtkozjZ etc]# ls
php-fpm-5.4.conf php-fpm-5.4.conf.bak
[root@iZwz99zpj9k5noj0vtkozjZ etc]# cp php-fpm-5.4.conf php-fpm-5.6.conf
[root@iZwz99zpj9k5noj0vtkozjZ etc]# ls
php-fpm-5.4.conf php-fpm-5.4.conf.bak php-fpm-5.6.conf
[root@iZwz99zpj9k5noj0vtkozjZ etc]#
