LNMPA (LNMP0.7) Installation appears 502 Bad Gateway Solution

What is LNMPA?
Linux + Nginx + MySql + PHP + Apache
 
How can this architecture be used?
Nginx and Apache are both website servers. How can they be installed? Yes. Nginx is used as a server to process static requests. If dynamic requests are enabled, Apache will be used. After all, Apache has been a Legacy Software for many years.
 
This construction has great advantages. The official website says, "LNMPA uses Nginx as a front-end service to provide faster and more timely static pages, js, images, etc, when a client requests to access a dynamic page, the Nginx reverse proxy is used by Apache. After Apache completes processing, it is handed over to Nginx and returned to the client.
The adoption of LNMPA can better solve the 502 error caused by PHP-FPM in the lnmp architecture, while providing a safer multi-user multi-site environment ."

Installation: the installation method is the same as that of Lnmp0.6. For details, refer to the installation method.
 
LNMP0.6 to 0.7?
In the above update records, we also saw that Nginx, MySQL, and PHP were upgraded from 0.7 to 0.6, and Apache was added. Therefore, we only need to decompress the full installation package and enter the directory to execute upgrade_nginx.sh, upgrade_php.sh, then run apache. sh.
 
For updates, it is best to uninstall 0.6 and then install 0.7.
