升级nginx，查看已经安装的模块，并隐藏或者修改版本号

[root@mail ~]# /opt/nginx/sbin/nginx -V
nginx version: nginx/0.5.34
built by gcc 3.4.6 20060404 (Red Hat 3.4.6-3)
configure arguments: --prefix=/opt/nginx --sbin-path=/opt/nginx/sbin/nginx --conf-path=/opt/nginx/conf/nginx.conf --pid-path=/var/run/nginx/nginx.pid 
--error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/opt/nginx/temp/proxy 
--http-fastcgi-temp-path=/opt/nginx/temp/fcgi --lock-path=/var/run/nginx/nginx.lock --with-http_ssl_module --with-http_sub_module 
--with-http_stub_status_module --with-debug

[root@mail nginx-0.8.39]# vi src/core/nginx.h
#define nginx_version         8039
#define NGINX_VERSION      "0.8.39"
#define NGINX_VER          "nginx/" NGINX_VERSION
改成：
#define nginx_version         8039
#define NGINX_VERSION      "0.0.0"
#define NGINX_VER          "netbig/" NGINX_VERSION

## 增加http_gzip和http_flv模块
./configure --prefix=/opt/nginx \

--with-http_sub_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-http_flv_module \
--with-debug
  
make
make install

[root@mail nginx-0.8.39]# nginxctl stop
Shutting down nginx:
