CentOS6.2/5.8下LNMP高性能的WEB服务器快速Yum搭建流程

本文将指导你如何在CentOS/Red Hat (RHEL) 6.2/5.8下使用Yum来搭建LEMP WEB服务器。国内

LNMP (Linux, Nginx, MySQL, PHP) 服务器目前在国内大的企业如百度腾讯使用非常普遍，但是因为LNMP不易安装配置，难为了许多运维人员。在本安装中，我尽量使用yum安装而避免编译安装，有将有效减少安装过程的时间及复杂程序。

LEMP（或LNMP）高性能的WEB服务器在CentOS6.2/5.8下的Yum搭建流程

STEP1.切换到root用户

su -
## OR ##
sudo -i

STEP2.安装必要的软件源

1. 安装Remi源

## Remi Dependency on CentOS 6 and Red Hat (RHEL) 6 ##
rpm -Uvh http://download.Fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm
 
## CentOS 6 and Red Hat (RHEL) 6 ##
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
 
 
## Remi Dependency on CentOS 5 and Red Hat (RHEL) 5 ##
rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
 
## CentOS 5 and Red Hat (RHEL) 5 ## 
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

2.配置Nginx 源

创建/etc/yum.repos.d/nginx.repo文件并写入以下内容

CentOS

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

RedHat(RHEL)

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/rhel/$releasever/$basearch/
gpgcheck=0
enabled=1

STEP3.安装Nginx

yum --enablerepo=remi,remi-test install nginx

STEP4.安装PHP5.4.4&PHP-FPM

yum --enablerepo=remi,remi-test install php php-fpm php-common

STEP5.安装PHP5.4.4模块扩展(一些扩展可能无用，请自行去除) 

yum --enablerepo=remi,remi-test install php-pecl-apc php-cli php-pear php-pdo php-mysql php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml

STEP6.停止并禁用httpd服务，启动Nginx HTTP服务及PHP-FPM

1.  停止httpd

/etc/init.d/httpd stop
## OR ##
service httpd stop
chkconfig httpd off

2.  启动Nginx

/etc/init.d/nginx start
## OR ##
service nginx start

3.  启动PHP_FPM

/etc/init.d/php-fpm start
## OR ##
service php-fpm start

4. 配置nginx使用PHP-FPM,修改/etc/nginx/conf.d/default.conf 

(1) 先为/etc/nginx/conf.d/default.conf作一个备份

cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf_bak

(2) 在default.conf 文件中，找到以下内容。

location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

修改为：

location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm index.php;
}

nginx默认的wwwroot文件夹为/usr/share/nginx/html，这里你可以修改为自己指定的目录
(3) 去除以下内容前的#号，并修改fastcgi_param所在行

#location ~ \.php$ {
#       root           html;
#       fastcgi_pass   127.0.0.1:9000;
#       fastcgi_index  index.php;
#       fastcgi_param  SCRIPT_FILENAME  [将此处修改为wwwroot路径]$fastcgi_script_name;
#        include        fastcgi_params;
#}

location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
}
