Rotten mud: learning how to quickly build an LNMP environment for centos, centoslnmp

I used to install software in centos in the source code, but yesterday I needed an LNMP environment in centos. Instead, I won't do it. I recorded it for future use.

1. Install nginx

Install nginx first, as shown below:

Yum-y install nginx

We can see that there is no nginx package in the current yum source. Install the yum Source Containing nginx as follows:

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

View the installed rpm package as follows:

Rpm-SQL nginx-release-centos-6-0.el6.ngx.noarch

Through this, we can clearly see that the rpm package just installed only adds a new nginx yum source. View the yum source as follows:

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

Now we can use yum to install nginx, as shown below:

Yum-y install nginx

We can see that nginx has been installed.

Now you can view the nginx installation location and its files as follows:

Rpm-ql nginx

We can see that nginx is installed in the/etc/nginx directory by default, while nginx is installed in the/usr/share/nginx/html directory by default.

Now let's start nginx and access nginx. As follows:

/Etc/init. d/nginx start

Curl http: // 192.168.1.124

View the users used during nginx running as follows:

Ps-ef | grep nginx

We can see that nginx is started by the root user, but nginx is used when running.

Ii. install php and php-fpm

Run the following command to install php and php-fpm:

Yum-y install php-fpm

View the php-fpm installation location and its file, as shown below:

Rpm-ql php-fpm

Start php-fpm and run the following command:

/Etc/init. d/php-fpm start

Ps-ef | grep php-fpm

Netstat-tunlp | grep 1355

We can see that apache is used when php-fpm is running, and php-fpm listens to port 9000 of the local machine.

If you want to modify the php-fpm runtime user and port, we can by modifying the php-fpm configuration file/etc/php-fpm.d/www. conf, as shown below:

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

Iii. Integration of nginx and php

Nginx and php are integrated through fastcgi, while fastcgi is usually used by php-fpm. In chapter 2, we have started php-fpm. Now we can modify the nginx configuration file to support php.

Now we modify the default nginx website 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. php index.html index.htm;

}

Error_page 500 502 503 x.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 above configuration is complete, restart nginx and php-fpm, as shown below:

/Etc/init. d/nginx restart

/Etc/init. d/php-fpm restart

The above is the default website for modifying nginx. Now we add a new nginx virtual host and make it support php, as shown below:

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

Server {

Listen 80;

Server_name test.ilanni.com;

Location /{

Root/ilanni;

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 complete, create index. php of the virtual host ilanni as follows:

Mkdir/ilanni

Vi/ilanni/index. php

<? Php phpinfo ();?>

Modify the user of the ilanni directory as follows:

Chown nginx: nginx-R/ilanni/

Ll/ilanni/

As shown in, we now change the ilanni directory to the user nginx used during nginx running.

Now let's modify the php-fpm runtime user as follows:

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

Restart nginx and php-fpm as follows:

/Etc/init. d/nginx restart

/Etc/init. d/php-fpm restart

Through this, we can see that the nginx virtual host can correctly parse php.

4. Install mysql

Run the following command to install MySQL:

Yum-y install mysql-server php-mysql

Start mysql after installation. As follows:

/Etc/init. d/mysqld start

Now we create a mysql. php file on the default nginx website to connect to the mysql database. The content of mysql. php 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, and mysql as follows:

/Etc/init. d/nginx restart

/Etc/init. d/php-fpm restart

/Etc/init. d/mysqld restart

Access the mysql. php file as follows:

Http: // 192.168.1.124/mysql. php

We can see that php has Parsed the mysql. php file and successfully connected to the mysql database.
