Nginx问题集锦

1. nginx 重启后日志文件报错
   nginx: [alert] could not open error log file: open() "/usr/local/var/log/nginx/error.log" failed (13: Permission denied)
   权限不够，加上

sudo nginx -s reload 

2. nginx.pid文件丢失，执行修复命令

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

“/usr/local/etc/nginx/nginx.conf”配置文件路径需要根据各机器而定，并不一定相同
