第二章 Centos7下yum安装Supervisor-3.4.0

一、安装Supervisor

[root@staging ~]# yum -y install supervisor

二、编辑配置文件

[root@staging ~]# vim /etc/supervisord.conf 
... ...
[inet_http_server]   #开启web界面访问
port=staging:12306	#这边主机名称+端口
... ...

三、编写子进程配置文件

[root@staging ~]# cat /etc/supervisord.d/frp.ini
#项目名
[program:frp]
#脚本目录
directory=/opt/frp_0.34.2_linux_amd64/
#脚本执行命令
command=/opt/frp_0.34.2_linux_amd64/frpc -c /opt/frp_0.34.2_linux_amd64/frpc.ini
#supervisor启动的时候是否随着同时启动,默认True
autostart=true
#当程序exit的时候,这个program不会自动重启,默认unexpected,设置子进程挂掉后自动重启的情况,有三个选项,false,unexpected和true。如果为false的时候,无论什么情况下,都不会被重新启动,如果为unexpected,只有当进程的退出码不在下面的exitcodes里面定义的
autorestart=true
#这个选项是子进程启动多少秒之后,此时状态如果是running,则我们认为启动成功了。默认值为1
startsecs=1
#脚本运行的用户身份 
user = root
#日志输出 
stderr_logfile=/tmp/blog_stderr.log 
stdout_logfile=/tmp/blog_stdout.log 
#把stderr重定向到stdout,默认 false
redirect_stderr = true
#stdout日志文件大小,默认 50MB
stdout_logfile_maxbytes = 20MB
#stdout日志文件备份数
stdout_logfile_backups = 20

四、启动supervisord

#1.设置开机自启
[root@staging ~]# systemctl enable supervisord.service
Created symlink from /etc/systemd/system/multi-user.target.wants/supervisord.service to /usr/lib/systemd/system/supervisord.service.

#2.启动supervisord
[root@staging ~]# systemctl start supervisord.service

#3.查看supervisord状态
[root@staging ~]# systemctl status supervisord.service
● supervisord.service - Process Monitoring and Control Daemon
   Loaded: loaded (/usr/lib/systemd/system/supervisord.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2021-11-18 12:29:03 CST; 48s ago
  Process: 9817 ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf (code=exited, status=0/SUCCESS)
 Main PID: 9821 (supervisord)
    Tasks: 1
   CGroup: /system.slice/supervisord.service
           └─9821 /usr/bin/python /usr/bin/supervisord -c /etc/supervisord.conf

Nov 18 12:29:03 staging systemd[1]: Starting Process Monitoring and Control Daemon...
Nov 18 12:29:03 staging systemd[1]: Started Process Monitoring and Control Daemon.

五、验证supervisor

#1.查看所有进程的状态
[root@staging ~]# supervisorctl status
frp                              RUNNING   pid 6890, uptime 0:00:06

#2.web界面查看(此处内网服务器部署,故没有设置密码,暴露公网建议加密)
