如何在CentOS 6上通過YUM安裝Nginx和PHP-FPM

原文地址：http://www.lifelinux.com/how-to-install-nginx-and-php-fpm-on-centos-6-via-yum/
開始安裝Nginx和PHP-FPM之前,你必須卸載系統中以前安裝的Apache和PHP。用root登錄輸入下面的命令：

# yum remove httpd* php*

增加額外資源庫
    默認情況下，CentOS的官方資源是沒有php-fpm的, 但我們可以從Remi的RPM資源中獲得，它依賴於EPEL資源。我們可以這樣增加兩個資源庫：

# yum install yum-priorities -y
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

如果你想在系統啟動時自動運行php-fpm，輸入下列命令：

# chkconfig level 345 php-fpm on

PHP僅安裝了核心模塊，你很可能需要安裝其他的模塊，比如MySQL、 XML、 GD等等，你可以輸入下列命令：

# yum enablerepo=remi install php-gd php-mysql php-mbstring php-xml php-mcrypt

第一次啟動php-fpm，輸入下列命令：

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

輸出樣例

Starting php-fpm: [ OK ]

配置PHP-FPM和Nginx，讓他們一起工作
nginx的配置文件在/etc/nginx/nginx.conf，輸入下列命令編輯這個文件：

# vi /etc/nginx/nginx.conf

像下面這樣編輯取消注釋：

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

重啟Nginx會重新讀取配置文件，輸入

# /etc/init.d/nginx reload

現在在
document root目錄下建立下列PHP文件

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

文件內容如下：

<?php
phpinfo();
?>

訪問 http://YOUR-SERVER-IP

Nginx虛擬主機設置 設置例子 IP: 192.168.1.113 Domain: domain.local Hosted at: /home/www/domain.local
輸入下列命令新建名叫“www”的用戶

# useradd www

創建必要的目錄

# mkdir -p /home/www/domain.local/public_html
# mkdir -p /home/www/domain.local/log
# chown -R www.www /home/www/
# chmod 755 /home/www/

創建虛擬主機配置文件

# cd /etc/nginx/conf.d/
# cp virtual.conf www.conf

輸入下面命令打開www.conf文件

# vi /etc/nginx/conf.d/www.conf

增加以下配置

server {
 server_name domain.local;
 root /home/www/domain.local/public_html;
 access_log /home/www/domain.local/log/domain.local-access.log;
 error_log /home/www/domain.local/log/domain.local-error.log;
 location / {
 index index.html index.htm index.php;
 }
 location ~ .php$ {
 include /etc/nginx/fastcgi_params;
 fastcgi_pass 127.0.0.1:9000;
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 }
}

你可以用下列方法檢查配置文件是否有語法錯誤

# /etc/init.d/nginx configtest

輸出樣例

the configuration file /etc/nginx/nginx.conf syntax is ok
configuration file /etc/nginx/nginx.conf test is successful

現在編輯
/etc/php-fpm.d/www.conf文件，將運行php-fpm進程的用戶改為“www”，輸入

# vi /etc/php-fpm.d/www.conf

找到“
group of processes”，編輯成下面的樣子：

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = www
; RPM: Keep a group allowed to write in log dir.
group = www

最後重啟nginx

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