nginx [warn] the "user" directive makes sense only if the maste

nginx配置了user   nginx nginx;
启动的时候直接报warn：
"[warn] 5052#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored 
in /opt/modules/nginx/conf/nginx.conf:2 "

办法一：使用root用户启动nginx就可以不报这个错

方法二：无视这个warn，并不影响正常业务
