nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"解决

部署flask项目，添加配置文件后，想重启一下nginx，结果报错：

  1. $ sudo nginx -s reload
  2. nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

原因分析：
nginx.pid丢掉了
解决：

  1. issued a nginx -s stop and after that I got this error when trying to reload it.
  2. [error]: invalid PID number “” in “/var/run/nginx.pid”
  3. That /var/run/nginx/pid file is empty atm.
  4. What do I need to do to fix it?
  5. nginx -s reload is only used to tell a running nginx process to reload its config. After a stop, you don't have a running nginx process to send a signal to. Just run nginx (possibly with a -c /path/to/config/file)

运行命令，问题得以解决：

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

  1. $ sudo /usr/sbin/nginx -c /etc/nginx/nginx.conf
