以http_realip_module為例
cd /usr/local/nginx-1.12.2
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_realip_module
make
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
cp objs/nginx /usr/local/nginx/sbin/
兩種方式重載nginx信號：
(1)自動
make upgrade
(2)手動
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
查看模塊情況：
/usr/local/nginx/sbin/nginx -V
