nginx安装报错：nginx: [error] invalid PID number “” in “/usr/local/nginx/logs/

搞了一个美国服务器，重新弄了下nginx安装配置，重新/usr/local/nginx/sbin/nginx -s reload 提示如下报错：

[[email protected] conf]# /usr/local/nginx/sbin/nginx   -s reload
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

无效的pid号。

网上搜索资料解决办法如下：

 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

重新查看nginx进程，现在是启动成功了。

[[email protected] conf]# netstat  -tunlp
