1,在redhat5.5安装的nginx，直接

[root@wincenter ~]# yum install nginx

2，nginx需要支持php，必须通过php-fpm，这个在安装php时添加参数

–enable-fpm

3,之前安装了php，需要重新编译安装，添加参数

[root@wincenter php-5.6.8]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-apxs2=/usr/sbin/apxs --with-mysql --enable-fpm

4，安装完毕后在/usr/local/php/etc目录下有个php-fpm.conf.default文件，直接copy一份出来

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

5,修改php-fpm.conf，去掉pid = run/php-fpm.pid的注释，以便启停

[global]
; Pid file
; Note: the default prefix is /usr/local/php/var
; Default Value: none
pid = run/php-fpm.pid

6，启动php-fpm

[root@wincenter etc]# /usr/local/php/sbin/php-fpm

7,检查php-fpm

[root@wincenter etc]# ps -ef | grep php-fpm | grep -v grep
root 8370 1 0 19:46 ? 00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
nobody 8371 8370 1 19:46 ? 00:00:02 php-fpm: pool www
nobody 8373 8370 1 19:46 ? 00:00:02 php-fpm: pool www

7，关闭php-fpm

[root@wincenter etc]# kill -INT `cat /usr/local/php/var/run/php-fpm.pid`

8，让nginx支持php，还需修改nginx的配置文件/etc/nginx/nginx.conf,将以下几行注释去掉

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;
}

9，重启nginx，servic nginx restart

10,创建测试文件

# vim /usr/share/nginx/html/index.php

11,在浏览器访问http://localhost/index.php

遇到问题：

1,yum install 时报错

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

解决方法：

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

2，configure 时报错，这是因为同时添加了apache和nginx的SAPI，分别为apxs和fpm

 You've configured multiple SAPIs to be build. You can build only one SAPI module and CLI binary at the same time.

解决方法：去掉apxs的配置参数

3,

error: xml2-config not found. Please check your libxml2 installation

缺少libxml2，安装即可

yum install libxml2 libxml2-devel
sudo apt-get install libxml2-dev

3,

nginx: [emerg] bind() to 0.0.0.0:8081 failed (13: Permission denied)

SELinux导致的，添加端口，或者直接关闭即可

4,

[pool www]pm.max_spare_servers(0) must be a positive value
failed topost process the configuration

修改php-fpm.conf文件内容

pm.start_servers=20
pm.min_spare_servers=5
pm.max_spare_servers=35
