centos php-fpm nginx配置

移除旧的软件包：yum remove httpd* php*
安装：yum install php php-fpm
yum install php-gd php-mysql php-mbstring php-xml php-mcrypt
验证配置文件：
/etc/init.d/nginx configtest
重启：
 /etc/init.d/nginx restart
 /etc/init.d/php-fpm restart  

出现这个错误可能是路径写错了：
Access denied.
nginx php-fpm 访问.php文件出现Access denied

也可能是权限，改为nginx:
vi /etc/php-fpm.d/www.conf 

; 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 = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx 

nginx节点配置示例：
server {
    listen       80;
    server_name  domain;
        root    /wwwdir;

    location / {
        index  index.html index.htm index.php;
    }

    #
    location ~ \.php$ {
        include fastcgi_params;
                fastcgi_pass  127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

}
