3. Configure using php-fpm

nginx and fastcgi There are two communication methods, one is TCP method, and the other is unix socket method

• TCP uses TCP port to connect 127.0.0.1:9000
• Socket uses unix domain Socket connection socket

1. TCP configuration method

• Edit /etc/nginx/conf.d/your site configuration file. Modify the fastcgi_pass parameter to 127.0.0.1:9000
• Edit the php-fpm configuration file /etc/opt/rh/rh-php71/php-fpm.d/www.conf

• Set the values of user and group to nginx
  user = nginx
group = nginx
• listen value setting is 127.0.0.1:9000, which is the same as the value of the fastcgi_pass parameter in the site configuration file

• After completion, we must change the selinux database and add port 9000 to serve httpd Valid connection.

semanage port -a -t http_port_t -p tcp 9000

• Restart php-fpm, restart nginx

2. Unix socket configuration method

Use a file (usually .sock) as the unique identifier (descriptor) of the socket. Two processes that need to communicate can establish a channel for communication by referencing the same socket descriptor file. .

• Create socket descriptor file

sudo touch /var/run/php7.1-fpm.sock sudo chown nginx:nginx /var/run/php7.1-fpm.sock sudo chmod 666 /var/run/php7.1-fpm.sock

• Modify the php-fpm configuration file

• The values of user and group are set to nginx
  user = nginx
group = nginx
• The value of listen is set to /var/run/php7. 1-fpm.sock, which is the same as the value of the fastcgi_pass parameter in the site configuration file
• Remove the semicolon in front of listen.owner, listen.group, and listen.mode to make php-fpm use unix socket and change The values of listen.owner and listen.group are set to nginx
  listen.owner = nginx
listen.group = nginx

• Modify the nginx site configuration file. Edit /etc/nginx/conf.d/your site configuration file. Change the fastcgi_pass parameter to /var/run/php7.1-fpm.sock
• Restart nginx and php-fpm services (it is best to restart php-fpm first and then restart nginx) [Recommended learning:PHP Video tutorial】
