./nginx -V
# 如果沒有我們需要的模塊，例如本次試驗添加的 –with-http_stub_status_module ，那么則需要重新編譯安裝一下

./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
# 這里是需要 make 編譯，不用 make install

# 找到 nginx 安裝包目錄 /root/nginx-1.10.1/objs ，將 nginx 文件復制到原本的 /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;
}

# 解釋說明：
	nginx_status	這是自定義命名的，訪問的時候添加這個字段訪問
	stub_status;	這個是固定參數(shù)
