nginx: [emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)

不要在/var/run目下建立新目录。

centos7（应该全部linux）下，建立了/var/run/nginx/目录存放nginx.pid，每次重启后，/var/run目录下都会清空！

解决方法：

[nginx@h10] /etc/nginx]$vi nginx.conf
#pid       /var/run/nginx/nginx.pid;
pid        /home/nginx/pid/nginx.pid;
