[root@xupan003 nginx]# sbin/nginx -s reload    从新加载配置文件
[root@xupan003 nginx]# sbin/nginx -t    检查配置文件是否正确
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

 

启动：./sbin/nginx【默认会加载conf下的nginx.conf】   或者  ./sbin/nginx -c conf/nginx.conf
