重新启动服务器，访问web服务发现无法浏览啦!登陆服务器之后进到nginx使用./nginx -s reload重新读取配置文件，发现报nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)错误，进到logs文件发现的确没有nginx.pid文件

　　[root@localhost sbin]# ./nginx -s reload

　　nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)

　　解决方法：

　　[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
