chmod a+x /etc/init.d/nginx  #設置文件的執行權限

然後，就可以通過該腳本對nginx服務進行管理了：

/etc/init.d/nginx start
/etc/init.d/nginx stop

使用chkconfig進行管理 
上面的方法完成了用腳本管理nginx服務的功能，比如要設置nginx開機啟動等。這時可以使用chkconfig來設置。 
先將nginx服務加入chkconfig管理列表：

chkconfig --add /etc/init.d/nginx

加完這個之後，就可以使用service對nginx進行啟動，重啟等操作了。

service nginx start
service nginx stop
設置終端模式開機啟動：

chkconfig nginx on

CentOS下設置nginx開機自動啟動和chkconfig管理
