5 Configuring nginx
The nginx configuration is in /etc/nginx/nginx.conf which we open now:
vi /etc/nginx/nginx.conf
The configuration is easy to understand (you can learn more about it here: http://wiki.codemongers.com/NginxFullExample and here: http://wiki.codemongers.com/NginxFullExample2)
First (this is optional) you can increase the number of worker processes and set the keepalive_timeout to a reasonable value:
[...] worker_processes 4; [...] keepalive_timeout 2; [...] |
The virtual hosts are defined in server {} containers. The default vhost is defined in the file /etc/nginx/conf.d/default.conf - let's modify it as follows:
vi /etc/nginx/conf.d/default.conf
[...] server { listen 80; server_name _; #charset koi8-r; #access_log logs/host.access.log main; location / { root /usr/share/nginx/html; index index.php index.html index.htm; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { try_files $uri =404; root /usr/share/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } } [...] |
server_name _; makes this a default catchall vhost (of course, you can as well specify a hostname here like www.example.com).
In the location / part, I've added index.php to the index line. root /usr/share/nginx/html; means that the document root is the directory /usr/share/nginx/html.
The important part for PHP is the location ~ \.php$ {} stanza. Uncomment it to enable it. Change the root line to the web site's dosument root (e.g. root /usr/share/nginx/html;). Please make sure that you change the fastcgi_param line to fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; because otherwise the PHP interpreter won't find the PHP script that you call in your browser.
Now save the file and reload nginx:
systemctl reload nginx.service
Now create the following PHP file in the document root /usr/share/nginx/html...
vi /usr/share/nginx/html/info.php
<?php phpinfo(); ?> |
Now we call that file in a browser (e.g. http://192.168.0.100/info.php):
As you see, PHP5 is working, and it's working through FPM/FastCGI, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5, including the MySQL module:
6 Making PHP-FPM Use A Unix Socket
By default PHP-FPM is listening on port 9000 on 127.0.0.1. It is also possible to make PHP-FPM use a Unix socket which avoids the TCP overhead. To do this, open /etc/php-fpm.d/www.conf...
vi /etc/php-fpm.d/www.conf
... and make the listen line look as follows:
[...] ;listen = 127.0.0.1:9000 listen = /tmp/php5-fpm.sock [...] |
Then restart PHP-FPM:
systemctl restart php-fpm.service
Next go through your nginx configuration and all your vhosts and change the line fastcgi_pass 127.0.0.1:9000; to fastcgi_pass unix:/tmp/php5-fpm.sock;, e.g. like this:
vi /etc/nginx/conf.d/default.conf
[...] location ~ \.php$ { try_files $uri =404; root /usr/share/nginx/html; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } [...] |
Finally reload nginx:
systemctl reload nginx.service
