启动Nginx出现这个错误:
nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)
解决方法：找到你的nginx.conf的文件夹目录，然后运行这个
nginx -c /usr/local/etc/nginx/nginx.conf命令，
再运行 sudo nginx -s reload，就可以了,
如下图所示：
nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)
