nginx 添加http_stub_status_module

./nginx -V
# 如果没有我们需要的模块，例如本次试验添加的 –with-http_stub_status_module ，那么则需要重新编译安装一下

./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_ssl_module --with-pcre --with-stream --with-http_stub_status_module

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

make
# 这里是需要 make 编译，不用 make install

# 找到 nginx 安装包目录 /root/nginx-1.10.1/objs ，将 nginx 文件复制到原本的 /usr/local/nginx/sbin/nginx
cp /root/nginx-1.10.1/objs/nginx /usr/local/nginx/sbin/

./nginx -s reload
./nginx -V

# 在文件中添加新的 location
location /nginx_status {
	stub_status;
}

# 解释说明：
	nginx_status	这是自定义命名的，访问的时候添加这个字段访问
	stub_status;	这个是固定参数
