Supervisor 安装调试记录

• yum install Supervisor
• 修改 vim /etc/supervisor.conf

    files = ./supervisor.d/*.conf

• 在 /etc/supervisor.d/ 目录下面安装自己要启动的进程 可以建立很多个
  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

• 启动下面命令
  sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-horzion:*

*这里面有个启动时候报错[ 解决办法]
使用supervisor守护frpc客户端进程，确保开机自启端口，记录报错过程。

报错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 ‘

解决：按照上面的提示，用supervisord 直接启动supervisor 会引起报错，故第一次启动的时候要加上配置文件。

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

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

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

解决：

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

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

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

解决：

1.需改权限

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

2.创建supervisor.sock文件

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

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

3.重启

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

报错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

解决：

[centos@localhost supervisor]$ ps -ef | grep supervisord #查看supervisord进程

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 #杀死进程

[centos@localhost supervisor]$ ps -ef | grep supervisord #确认进程supervisord被杀死

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

[centos@localhost supervisor]$ sudo supervisord -c /etc/supervisord.conf #启动新的supervisord进程

记得设置开机自启：systemctl enable supervisord

验证：systemctl is-enabled supervisord
