Centos 6.X LNMP installation and deployment

Note: When managing the server, it is strongly recommended to use a normal user!

The LNMP (ie nginx-mysql-php) server has always been considered a server with high performance and low memory usage. Let's introduce how to install it through a simple YUM command 

1. Preparation

1. Configure the firewall, open port 80 and port 3306

vim /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #Allow port 80 to pass through the firewall           

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #Allow port 3306 to pass through the firewall       

The correct one should be to add to the default 22 port rule and save it, and restart iptables  /etc/init.d/iptables restart 

2. Close SELINUX (best to close)

 

vim /etc/selinux/config

#SELINUX=enforcing  #Comment out
#SELINUXTYPE=targeted #Comment  out
SELINUX=disabled  #Add
:wq  #Save and exit
shutdown -r now #Restart the  system

Or temporarily shut down:

$ sudo setenforce 0

$ status    

 

 

3. Install the C compiler: 
yum -y install gcc gcc-c++ autoconf automake

4.Install the third-party yum source
sohu source address (64-bit source): http://mirrors.sohu.com/fedora-epel/6/x86_64 / 
centos 6.X 64bit: 
rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
rpm -ivh http ://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm

2. Install mysql

1. Uninstall the apache that comes with the system first, and then update the software library 

yum -y remove httpd 
yum update

2, yum install mysql 

It is recommended to use one of the following <1> or <2> methods for installation:

<1>[mysql directory] [★]centos6.5 uses yum to install mysql5.6

<2>[mysql directory] [★] Install MariaDB 10 on CentOS 6.5

<3> 直接安装
yum -y install mysql-server

3、加入启动项并启动mysql 

chkconfig --levels 235 mysqld on 
/etc/init.d/mysqld start

4、设置mysql密码及相关设置 

/usr/bin/mysqladmin -u root password '123456' // 第一次，为root账号设置密码

也可参考：mysql_secure_installation 
因为第一次启动这命令，所以直接回车下一步，然后输入你的mysql密码，按照提示操作。 

三、安装nginx

 

1、yum安装nginx 

yum -y install nginx 

2、添加到启动项并启动nginx 

chkconfig --levels 235 nginx on 
/etc/init.d/nginx start 

四、安装php 

 

文章来源： http://webtatic.com/packages/php55/

 

这里使用 Webtatic EL6的YUM源来安装php5.5

 

建议安装前，先卸载以前的php再进行安装，使用：

 

yum remove php php-*

CentOS/RHEL 7.x:

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

 

CentOS/RHEL 6.x:

rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm 

 

CentOS/RHEL 5.x:

rpm -Uvh https://mirror.webtatic.com/yum/el5/latest.rpm

 

安装php5.5

yum -y install php55w php55w-common php55w-mysql php55w-fpm php55w-gd php55w-imap php55w-mbstring php55w-mcrypt php55w-pdo php55w-soap php55w-tidy php55w-xml php55w-xmlrpc php55w-devel php55w-pgsql

安装项可以参考“ [LNMP目录中] PHP 5.4 on CentOS/RHEL 6.2”

 

五、相关配置

 

1、PHP配置

<1> 编辑文件php.in

 

vim /etc/php.ini

修改： 
short_open_tag = On 
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE 
date.timezone = PRC 

request_order = "CGP"
保存 

<2> 启动php-fpm 

service php-fpm start 

<3> php-fpm加入启动项 

chkconfig --levels 235 php-fpm on

修改nginx配置文件，添加fastcgi支持 

2、nginx配置

修改nginx.conf文件 :vi /etc/nginx/nginx.conf

配置多站点虚拟域名：配置/etc/nginx/nginx.conf，确认能够引入/etc/nginx/conf.d中配置已.conf为后缀的配置文件（后缀自定义）
<1> 配置文件部分代码： 
server{ 
listen 80; 
root /home/www/test; 
index index.php index.html index.htm; 
server_name www.test.com; 

if (!-e $request_filename) { 
rewrite ^(.*)$ /index.php?s=$1 last; 
break; 
} 

try_files $uri $uri/ /index.php?$args; 
#try_files $uri $uri/ /index.php?s=$uri; 
location ~ \.php { 
fastcgi_pass 127.0.0.1:9000; 
#fastcgi_pass unix:/var/run/php5-fpm.sock; 
fastcgi_index index.php; 
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
include fastcgi_params; 
} 
} 

<２> 重启nginx php-fpm

/etc/init.d/nginx restart 
/etc/init.d/php-fpm restart 

<3> 建立info.php文件 

vi /usr/share/nginx/html/info.php

添加如下代码： 
<?php 
phpinfo(); 
?> 

在浏览器打开测试是否正常，如 http://www.test.com/info.php(记得hosts文件进行配置)。

六、其它注意项

1、【mysql目录】centos 6.5 修改mysq数据库目录问题

2、【mysql目录】当mysql开启bin-log，请查看“This function has none of DETERMINISTIC, NO SQL解决办法”

3、【nginx目录】nginx提示：413 Request Entity Too Large (设置nginx上传大小限制)

4、【PHP目录】[★] php上传下载文件大小限制
