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

此报错为：logs目录下缺少pid文件。

解决方式：重新指定启动之时加载的配置文件，然后再重启，假如nginx的配置文件目录为：/usr/local/nginx/conf/nginx.conf

先执行命令：/usr/local/nginx/sbin/nginx  -c/usr/local/nginx/conf/nginx.conf

然后再：/usr/local/nginx/sbin/nginx -s reload 进行平滑重启就不会报错了

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