Supervisor 安裝除錯記錄

yum install Supervisor
修改 vim /etc/supervisor.conf
```
  files = ./supervisor.d/*.conf
```

在 /etc/supervisor.d/ 目錄下面安裝自己要啟動的程式可以建立很多個
eg:laravl-horizon.conf

      [program:laravel-horizon]
      process_name=%(program_name)s_%(process_num)02d
      command=php /www/wwwroot/fox/artisan horizon   
      autostart=true
      autorestart=true
      user=zhangdd
      numprocs=4
      redirect_stderr=true
      stdout_logfile=/www/wwwroot/fox/storage/logs/horizon.log
      stopwaitsecs=1200

啟動下面命令
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-horzion:*

*這裡面有個啟動時候報錯[ 解決辦法]
使用supervisor守護frpc客戶端程式，確保開機自啟埠，記錄報錯過程。

報錯1：[centos@localhost supervisor]$ sudo supervisord

/usr/lib/python2.7/site-packages/supervisor/options.py UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a “-c” argument specifying an absolute path to a configuration file for improved security.

‘Supervisord is running as root and it is searching ‘

解決：按照上面的提示，用supervisord 直接啟動supervisor 會引起報錯，故第一次啟動的時候要加上配置檔案。

[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf

報錯2：[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf

Unlinking stale socket /var/run/supervisor/supervisor.sock

解決：

[centos@localhost supervisor]$ unlink /var/run/supervisor/supervisor.sock

報錯3：[centos@localhost supervisord.d]$ sudo supervisorctl status

unix:///var/run/supervisor/supervisor.sock no such file

解決：

1.需改許可權

sudo chmod 777 /run
sudo chmod 777 /var/log

2.建立supervisor.sock檔案

[centos@localhost supervisord.d]$ sudo touch /var/run/supervisor/supervisor.sock

[centos@localhost supervisord.d]$ sudo chmod 777 /var/run/supervisor/supervisor.sock

3.重啟

[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf

報錯4：[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf

Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.

For help, use /bin/supervisord -h

解決：

[centos@localhost supervisor]$ ps -ef | grep supervisord #檢視supervisord程式

root 13000 1 0 16:59 ? 00:00:00 /usr/bin/python /bin/supervisord

centos 13347 3471 0 17:00 pts/0 00:00:00 grep –color=auto supervisord

[centos@localhost supervisor]$ sudo kill -s SIGTERM 13000 #殺死程式

[centos@localhost supervisor]$ ps -ef | grep supervisord #確認程式supervisord被殺死

centos 13664 3471 0 17:01 pts/0 00:00:00 grep –color=auto supervisord

[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf #啟動新的supervisord程式

記得設定開機自啟：systemctl enable supervisord

驗證：systemctl is-enabled supervisord
