LNMP installing multiple Versions of PHP

The PHP7 version was installed through LNMP, but was found to be incompatible with the program and needed to be reduced to a version below 7.0.

1. to find the install.sh file for LNMP, typically under/root/lnmp1.5/install.sh
2. execute command

   sudo./install.sh mphp
   
   Waiting for the installation process

3. installation ends
   
4. has multiple versions of PHP
   
   5. There will be one more/usr/local/nginx/conf under the enable-php5.6.conf
   
5. need to modify Nginx configuration, Find include enable-php.conf; modified to include enable-php5.6.conf;
   
6. Restart sudo lnmp restart
   
   8. Disable the original version of PHP

   /ETC/INIT.D/PHP-FPM {start|stop|quit|restart| Reload|logrotate}
   Note:

7. There may be a 502 error accessing the Web page, viewing nginx error.log found the following log:

   2018/ 08/02 06:44:20 [Crit] 11744#0: *46 connect () to Unix:/tmp/php-cgi.sock failed (2:no such file or directory) while Connect ing to upstream, client:114.244.134.66, server:tpshop.goldblockchain.org.cn, Request: "get/http/1.1", Upstream: "FASTC Gi://unix:/tmp/php-cgi.sock: ", Host:" tpshop.goldblockchain.org.cn "

Requires nginx.conf with php-fpm.conf about/tmp/php-cgi.sock configuration to be unified, because the sock name will be different if you install another version of PHP
