重启Nginx报错： nginx: [error] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory )
停掉nginx 或者重启nginx报错：nginx: [error] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory)
进入logs发现并没有nginx.pid文件
解决办法：/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
