Slime: Learn the Quick build LNMP environment of CentOS

This article consists of Su Yi Lin Feng provide sponsorship, starting in Slime Line the world

Previously installed under the CentOS software are like source installation, but yesterday because of a thing need a centos under the LNMP environment. Instead of doing it, it was deliberately recorded today for future use.

First, install Nginx

Let's install Nginx first, as follows:

Yum-y Install Nginx

Through, we can see that there is no nginx software package in the current Yum source. We need to install a Yum source with Nginx, as follows:

RPM-IVH http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

View the RPM package just installed, as follows:

RPM-QL Nginx-release-centos-6-0.el6.ngx.noarch

Through, we can clearly see just installed RPM package, just add a new nginx yum source. View the Yum source as follows:

Cat/etc/yum.repos.d/nginx.repo

Now let's install Nginx via Yum, as follows:

Yum-y Install Nginx

Through, we can clearly see that Nginx has been installed.

Now look at the location of the Nginx installation and its files as follows:

RPM-QL Nginx

Through, we can obviously see Nginx installed to the/etc/nginx directory by default, and Nginx's default website is installed in the/usr/share/nginx/html directory.

Now let's start the Nginx and visit Nginx. As follows:

/etc/init.d/nginx start

Curl http://192.168.1.124

Look at the user who used the Nginx runtime as follows:

Ps-ef |grep Nginx

Through, we can clearly see that nginx is the root user to start, but Nginx is running with the Nginx user.

Second, install PHP and PHP-FPM

To install PHP and PHP-FPM, use the following command:

Yum-y Install PHP php-fpm

View the location of the PHP-FPM installation and its files as follows:

RPM-QL PHP-FPM

To start PHP-FPM, use the following command:

/ETC/INIT.D/PHP-FPM start

Ps-ef |grep PHP-FPM

NETSTAT-TUNLP |grep 1355

Through this, we can see that the PHP-FPM runtime uses Apache as the user, and php-fpm listens to the native port 9000.

If you want to modify the PHP-FPM runtime user and port, we can modify the PHP-FPM configuration file/etc/php-fpm.d/www.conf, as follows:

cat/etc/php-fpm.d/www.conf |grep-v ' ^; ' | Grep-v ^$

third, nginx and PHP integration

Nginx and PHP integration is achieved through fastcgi, and fastcgi we generally use is php-fpm. In chapter two, we have started php-fpm, and now we are going to modify the Nginx configuration file to support PHP.

Now we modify Nginx's default Web site configuration file default.conf, as follows:

Cat/etc/nginx/conf.d/default.conf

server {

Listen 80;

server_name localhost;

Location/{

root/usr/share/nginx/html;

Index index.php index.html index.htm;

}

Error_page 502 503 504/50x.html;

Location =/50x.html {

root/usr/share/nginx/html;

}

Location ~ \.php$ {

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;

}

}

After the configuration is complete, we re-restart Nginx and PHP-FPM, as follows:

/etc/init.d/nginx restart

/ETC/INIT.D/PHP-FPM restart

The above is modified nginx default website, now we add an nginx virtual host, and make IT support PHP, as follows:

Vi/etc/nginx/conf.d/ilanni.conf

server {

Listen 80;

server_name test.ilanni.com;

Location/{

Root/ilanni;

Index index.php index.html index.htm;

}

Location ~ \.php$ {

Root/ilanni;

Fastcgi_pass 127.0.0.1:9000;

Fastcgi_index index.php;

Fastcgi_param script_filename $document _root$fastcgi_script_name;

Include Fastcgi_params;

}

}

After the Nginx virtual host configuration file is finished, now to create the virtual host Ilanni index.php, as follows:

Mkdir/ilanni

vi/ilanni/index.php

<?php phpinfo ();?>

Modify the owning user of the Ilanni directory as follows:

Chown Nginx:nginx-r/ilanni/

ll/ilanni/

As shown, we now change the Ilanni directory to the user Nginx used by Nginx runtime.

Now let's modify the user of the PHP-FPM runtime as follows:

Vi/etc/php-fpm.d/www.conf

We will restart Nginx and php-fpm as follows:

/etc/init.d/nginx restart

/ETC/INIT.D/PHP-FPM restart

Through, we can see Nginx virtual host has been able to correctly parse PHP.

iv. installation of MySQL

To install MySQL, use the following command:

Yum-y install MySQL mysql-server php-mysql

When the installation is complete, start MySQL. As follows:

/etc/init.d/mysqld start

Now we create a mysql.php file in the Nginx Default Web site to connect to the MySQL database. mysql.php content is as follows:

cat/usr/share/nginx/html/mysql.php

<?php

$host = ' localhost ';

$root = ' root ';

$pwd = ";

$con = mysql_connect ($host, $root, $pwd);

if ($con = = False) {

echo "Connect false";

} else{

echo "Connect true";

}

?>

Restart Nginx, PHP-FPM, MySQL, as follows:

/etc/init.d/nginx restart

/ETC/INIT.D/PHP-FPM restart

/etc/init.d/mysqld restart

Now by accessing the mysql.php file, as follows:

http://192.168.1.124/mysql.php

Through, we can clearly see that PHP has parsed the mysql.php file, and has successfully connected to the MySQL database.
