This article mainly introduces "how to build a LNMP HTTP web server under CentOS". In daily operation, I believe many people have doubts about how to build a LNMP HTTP web server under CentOS. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to build a LNMP HTTP web server under CentOS". Next, please follow the editor to study!

The basic configuration of the new vps is as follows:

Virtualization technology: openvz operating system: centos-6 x86x64 basecpu: intel (r) xeon (r) cpu E3-1240 v2 @ 3.40ghz memory: 2gb hard disk: 50gb hdd

First, prepare to work ssh login vps, scp upload files

Log in to vps with ssh

In linux, to remote management of a server, is a very easy and pleasant thing, ssh command is used to log in to the remote host, login into the shell command line mode, and then as in the terminal to operate their own machine to operate the remote host on it, the only need to pay attention to is not to write the command wrong, such as rm-rf. / * written as rm-rf / *.

The general usage of the ssh command is:

Ssh user name @ hostname-p host ssh service port number

The default port number of the ssh service is 22. When using the default port, the-p option is optional. When you connect a host remotely for the first time, you will be prompted that the authenticity of the host cannot be confirmed. Ask if you want to continue (yes/no), and enter "yes" to continue the connection. Take logging in 198.98.117.120 as an example:

Carey@e530:~$ ssh root@198.98.117.120-p 22

Scp uploads files

The scp command can copy files between the local machine and the remote host. Based on ssh service, the general usage is as follows:

Copy files from the local machine to the remote host:

The copy code is as follows:

Scp-p ssh service port number local file path destination host user name @ host name: storage path

Copy files from the remote host to the local:

The copy code is as follows:

Scp-p ssh service port number target host username @ hostname: file path local storage path

Take uploading the files needed to configure the lnmp environment as an example, nginx's source code package nginx-1.6.0.tar.gz, php's source code package php-5.5.10.tar.gz, and a new terminal:

The copy code is as follows:

Carey@e530:~/download$ scp-p 22 nginx-1.6.0.tar.gz root@198.98.117.120:/home/upload

Carey@e530:~/download$ scp-p 22 php-5.5.10.tar.gz root@198.98.117.120:/home/upload

II. Compile and install nginx and php

First, take a look at some of the software packages pre-installed in vps's centos system:

Yum list installed

Clean up the built-in apache, php, mysql services (if any) and execute the command:

Yum remove httpd mysql-server mysql php

Check if gcc is installed, execute the command gcc-v if not installed, perform yum installation:

Yum install gcc

Installing gcc is necessary because we will compile the installation of nginx and php below.

Install nginx

Create nginx and php dedicated users and user groups

[root@widlabs ~] # groupadd www

[root@widlabs] # useradd-s / sbin/nologin-m-g www nginx

Dependencies required to install nginx

[root@widlabs ~] # yum install pcre-devel

[root@widlabs ~] # yum install zlib-devel

Compile and install nginx

The copy code is as follows:

[root@widlabs ~] # cd / home/upload # enter the directory where the nginx source package is located

[root@widlabs upload] # tar tar zxvf nginx-1.6.0.tar.gz

[root@widlabs upload] # cd nginx-1.6.0

[root@widlabs nginx-1.6.0] # / configure-- prefix=/usr/local/nginx-- user=nginx-- group=www-- with-pcre

[root@widlabs nginx-1.6.0] # make

[root@widlabs nginx-1.6.0] # make install

Install php

Dependencies required to install php

The copy code is as follows:

[root@widlabs nginx-1.6.0] # cd / home/upload # enter the directory where the php source package is located

# if the wget command is available, execute:

[root@widlabs upload] # wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.6.tar.gz

# Note: when wget is not available, you can first yum install wget, or download the libmcrypt-2.5.6.tar.gz source package from ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/, and then upload it to vps using the scp command

[root@widlabs upload] # tar zvxf libmcrypt-2.5.6.tar.gz

[root@widlabs upload] # cd libmcrypt-2.5.6

[root@widlabs libmcrypt-2.5.6] #. / configure-prefix=/usr/local/libmcrypt

[root@widlabs libmcrypt-2.5.6] # make

[root@widlabs libmcrypt-2.5.6] # make install

[root@widlabs libmcrypt-2.5.6] # cd..

[root@widlabs upload] # yum install libxml2-devel

Compile and install php

The copy code is as follows:

[root@widlabs upload] # tar zxvf php-5.5.10.tar.gz

[root@widlabs upload] # cd php-5.5.10

[root@widlabs php-5.5.10] # / configure-- prefix=/usr/local/php-- with-config-file-path=/usr/local/php-- with-mysql-- with-mysqli-- with-pdo-mysql-- enable-opcache-- enable-mbstring-- enable-mbregex-- with-mcrypt=/usr/local/libmcrypt-- with-mhash-- enable-cgi-- enable-fpm # can add corresponding compilation options according to your own needs

[root@widlabs php-5.5.10] # make

[root@widlabs php-5.5.10] # make install

[root@widlabs php-5.5.10] # cp php.ini-development / usr/local/php/php.ini

[root@widlabs php-5.5.10] # cd / usr/local/php/etc

[root@widlabs etc] # cp php-fpm.conf.default php-fpm.conf

Third, install mysql

Mysql can be installed directly through yum:

[root@widlabs ~] # yum install mysql mysql-server mysql-devel

4. Configure nginx and php

Configuration of nginx

The copy code is as follows:

[root@widlabs ~] # cd / usr/local/nginx/conf

[root@widlabs conf] # cp nginx.conf nginx.conf.bak

[root@widlabs conf] # vi nginx.conf

Server {

Listen 80

Server_name widlabs.com www.widlabs.com; # website domain name

# charset koi8-r

# access_log logs/host.access.log main

Location / {

Root html

Index index.html index.htm index.php; # add index.php

}

# error_page 404 / 404.html

# redirect server error pages to the static page / 50x.html

#

Error_page 500 502 503 504 / 50x.html

Location = / 50x.html {

Root 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

# remove the comments from these lines and make minor changes

Location ~\ .php$ {

Root html

Fastcgi_pass 127.0.0.1:9000

Fastcgi_index index.php

# fastcgi_param script_filename / scripts$fastcgi_script_name; changed to

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

#}

}

Configuration of php

The copy code is as follows:

[root@widlabs ~] # vi / usr/local/php/php.ini

[date]

; defines the default timezone used by the date functions

; http://php.net/date.timezone

Date.timezone = prc

Fifth, test whether the configuration is correct

The copy code is as follows:

[root@widlabs ~] # cd / usr/local/nginx/html # / usr/local/nginx/html is the default working directory of the website

[root@widlabs html] # echo'> test.php # create a new test.php to execute the test as php

[root@widlabs html] # service mysqld start # start the mysql service

[root@widlabs html] # / usr/local/php/sbin/php-fpm # launch php fastcgi Manager

[root@widlabs html] # / usr/local/nginx/sbin/nginx # start nginx

Access the host ip and test.php through the browser to determine whether nginx is working properly.

VI. Self-startup of nginx website service

The copy code is as follows:

[root@widlabs ~] # vi / etc/rc.local

#! / bin/sh

#

# this script will be executed * after* all the other init scripts.

# you can put your own initialization stuff in here if you don't

# want to do the full sys v style init stuff.

Touch / var/lock/subsys/local

# add

/ sbin/service mysqld start

/ usr/local/php/sbin/php-fpm

/ usr/local/nginx/sbin/nginx

Restart vps to determine whether the boot self-boot is correct:

[root@widlabs ~] # reboot now

7. Resolve domain name to server ip

Log in to the management panel provided by the domain name service provider, select domain name resolution, type select a record, and the record value is to point to the host ip.

At this point, the http infrastructure of the entire lnmp is built.

At this point, the study on "how to build a LNMP HTTP web server under CentOS" is over. I hope to be able to solve your doubts.
