注意：
RS的日志格式中也需要指定记录客户端IP才可以。

如果后端RS添加记录真实的IP之后，语法检查无法通过，可能是--with-http_realip_module 模块没有安装。
在已经安装的nginx服务上门，添加nginx模块方法如下
##添加新模块
1.查看nginx编译安装时的命令，安装了哪些模块
/application/nginx/sbin/nginx -V
2.加入需要安装的模块，重新编译
pkill nginx
cd /home/lvnian/tools/nginx-1.6.2
./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.2 --with-http_stub_status_module --with-http_realip_module --with-http_ssl_module
make
make就可以了，但是不要make install，否则会覆盖
make
3. 替换nginx二进制文件:
cp /app/nginx/sbin/nginx /app/nginx/sbin/nginx.bak
cp ./objs/nginx /app/nginx/sbin/
4.启动nginx
/application/nginx/sbin/nginx -V
/application/nginx/sbin/nginx -t
/application/nginx/sbin/nginx
