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

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文件发现没有nginx.pid文件

使用nginx -c的参数指定nginx.conf文件的位置

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

示：nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

killall -9 nginx

杀掉nginx 进程 然后重启就行了。

service nginx restart

另外 还有一个很重要的可能

ps -ef | grep nginx
