Detailed explanation of how to configure fpm socket when upgrading Ubuntu to php7.0

Simply put

(That’s all I know), nginx handles requests through fpm (to manage fastcgi) to implement requests and responses.

nginx and php-fpm can be implemented by listening to port 9000 (default) or socket.

The format of 9000 is 127.0.0.1:9000, which is over the network. Through the ngxin conf file, everything ending in .php is handed over to port 9000 for processing. php-fpm (fastggi's process manager) selects and connects to a fastcgi sub-process, and sends environment variables and standard input to the fastcgi sub-process. Then continuously process the request and response

The socket file does not go through the network, it is a socket.

Okay, as for speed comparison and optimized configuration, let’s not talk about it for now.

Let’s talk about the ubuntu (14.10 lts) upgrade firstphp7

sudo add-apt-repository ppa:ondrej/php-7.0
sudo apt-get update
sudo apt-get install php7.0-fpm

After the upgrade is completed, the previous fpm file is still there. You can refer to or delete as appropriate

php -v
PHP 7.0.1-4+deb.sury.org~trusty+1 (cli) ( NTS )
Copyright (c) 1997-2015 The PHP Group

Change the phpfpm listening port 9000 to socket (the default is socket)

php7 defaults to socket, so if According to the previous nginx -conf file, php file processing will report a 502 error.

The default sock is in the php configuration file. www.conf

root@tb:/etc/php/7.0/fpm# pwd
/etc/php/7.0/fpm
root@tb:/etc/php/7.0/fpm# ls
conf.d  php-fpm.conf  php.ini  pool.d
root@tb:/etc/php/7.0/fpm#

in pool.d is in these two lines:

listen = /run/php/php7.0-fpm.sock
; listen = 127.0.0.1:9000
## 更改nginx conf文件 ##

nginx configuration file Mine is In

  root@tb:/etc/nginx/conf.d# ls
  git.conf  svn.conf  tb.conf

modify the git.conf as follows

 server{
    listen 80;
    server_name git.com ;
    root /home/gittest/;
    autoindex on;
  location ~ \.php$ {
    root           /home/gittest;
    #fastcgi_pass   127.0.0.1:9000;
    fastcgi_pass    unix:/run/php/php7.0-fpm.sock;
    fastcgi_index  index.php;
    fastcgi_intercept_errors        on;
    fastcgi_param  SCRIPT_FILENAME  /home/gittest/$fastcgi_script_name;
    include        fastcgi_params;
    }
}

Restart php-fpm and nginx

    root@tb:/etc/nginx/conf.d# service nginx reload
     * Reloading nginx configuration nginx                                                                           [ OK ] 
     
    root@tb:/etc/nginx/conf.d# service php7-fpm status
     * php-fpm7.0 is running
    root@tb:/etc/nginx/conf.d# service php7-fpm reload
     * Reloading PHP 7.0 FastCGI Process Manager php-fpm7.0[ OK ] 
    root@tb:/etc/nginx/conf.d#

Please note that it is OK. The specific nginx and fpm script execution files (can be modified by yourself) are at:

    root@tb:/etc/init.d# ls /etc/init.d/ |grep php7
    php7-fpm
    root@tb:/etc/init.d# ls /etc/init.d/ |grep nginx
    nginx
    root@tb:/etc/init.d#

Additional: If you want to change back to the previous version through apt-get

sudo add-apt-repository ppa:ondrej/php5
sudo apt-get update

Then just install it
