configure nginx to work with php and mysql server on ubuntunow we have all components installed. the next step is we need to configure nginx with php and mysql. let's start to configure them.
#1 - configure php5-fpmphp5-fpm configuration file is located at /etc/php5/fpm/php.ini. open it with your text editor
$ sudo vi /etc/php5/fpm/php.ini
cgi.fix_pathinfo=1
cgi.fix_pathinfo=0
$ sudo service php5-fpm restart
#2 - configure nginxnginx configuration file is located at /etc/nginx/nginx.conf. but basically, we don't need to touch it. the configuration of nginx website is located in /etc/nginx/sites-available/default file.
location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; # # note: you should have cgi.fix_pathinfo = 0; in php.ini # # # with php5-cgi alone: # fastcgi_pass 127.0.0.1:9000; # # with php5-fpm: fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }
then restart the services.
$ sudo service nginx restart
$ tail /var/log/nginx/error.log
fastcgi_pass unix:/var/run/php5-fpm.sock
location ~ \.php$ {
#3 - configure mysqlafter the configuration section is done, now we need to test them to make sure that our configuration is working as required. on ubuntu 14.04 the root document folder is located in /usr/share/nginx/html. so create a file called /usr/share/nginx/html/phpinfo.php with the following code:
[php] view plaincopyafter restarting php-fpm and nginx, open the browser and browse to the php file, we got only a blank screen. no error message on the screen. no error message on php-fpm and nginx log file.
and then open the browser again and type url http://your_ip_address/phpinfo.php
... your code ... ?>to enable short php tag, we need to change the value of short_open_tag parameter on php.ini file:
sudo service php5-fpm restartthen try again to test your phpinfo file. next, we will see if the mysql support is enabled or not. scroll down the php configuration screen on your browser, if you see mysql block there, then mysql support already enabled.you are now ready to use nginx, php5 and mysql on ubuntu server. i hope this quick article help anyone who wish to install linux, nginx, php and mysql on ubuntu 14.04.
