在存储服务上操作（storge）

1.安装依赖(st-01 st-02)

命令：[root@storage01 ~]# yum install -y pcre pcre-devel openssl openssl-devel gd-devel

命令：[root@storage02 ~]#yum install -y pcre pcre-devel openssl openssl-devel gd-devel

2.杀掉nginx进程后编译nginx（以st-01为例）

命令：[root@storage01 ~]# ps aux | grep nginx

命令：[root@storage01 ~]# kill -9 6462

3.重新编译nginx，添加模块

命令：[root@storage01 ~]# cd /myself_settings/nginx-1.7.8

命令：[root@storage01 nginx-1.7.8]# ./configure --prefix=/usr/local/nginx --with-http_image_filter_module --add-module=/myself_settings/fastdfs-nginx-module/src

命令：[root@storage01 nginx-1.7.8]# make && make install

4.配置nginx解析

命令：[root@storage01 nginx-1.7.8]# vim /usr/local/nginx/conf/nginx.conf

将以下配置文件拷贝进去

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid        logs/nginx.pid;
