3. 安装supervisor

   yum -y --nogpgcheck install epel-release
   yum -y --nogpgcheck install python-pip
   
   pip install --upgrade pip
   pip install supervisor
   

4. 生成配置文件

   echo_supervisord_conf > /etc/supervisord.conf
   

5. 修改配置

   ; 进程管理,可以单独写到'/etc/supervisord/*.conf'文件内
   [program:进程名1]
   command=[要管理的进程命令]     ; the program (relative uses PATH, can take args)
   process_name=%(program_name)s  ; process_name expr (default %(program_name)s)
   numprocs=1                     ; number of processes copies to start (def 1)
   directory=/tmp                 ; directory to cwd to before exec (def no cwd)
   priority=999                   ; the relative start priority (default 999)
   autostart=true                 ; start at supervisord start (default: true)
   startsecs=1                    ; # of secs prog must stay up to be running (def. 1)
   startretries=5                 ; max # of serial start failures when starting (default 3)
   autorestart=unexpected         ; when to restart if exited after running (def: unexpected)
   user=www                       ; setuid to this UNIX account to run the program
   
   ; 进程组管理
   [group:进程组名]
   programs=进程名1,进程名2       ; each refers to 'x' in [program:x] definitions
   priority=999                   ; the relative start priority (default 999)
   
   [include]
   files = /etc/supervisord/*.conf
   

6. 完全相同进程启动多个

   参考链接

   [program:进程名2]
   process_name=%(program_name)s_%(process_num)02d ;进程名格式
   command=xxxxxxxxx                               ;进程
   autostart=true                                  ;自动启动
   autorestart=true                                ;自动重启
   user=www                                        ;运行用户
   numprocs=8                                      ;进程数
   

7. 启动进程管理服务

   supervisord -c /etc/supervisord.conf
   

8. 进入进程管理控制台

   supervisorctl -c /etc/supervisord.conf
   

9. 启动所有进程

   # 重新加载配置
   supervisor> reload
   # 重新读取进程
   supervisor> reread
   # 启动所有进程
   supervisor> start all
   

10. 管理相关命令

    # 重新读取进程
    supervisor> reread
    # 重新加载配置
    supervisor> reload
    # 启动所有进程
    supervisor> start all
    # 停止所有进程
    supervisor> stop all
    # 重启所有进程
    supervisor> restart all
    # 添加进程
    supervisor> add [进程名]
    supervisor> tail   
    supervisor> avail
    supervisor> fg
    supervisor> pid
    supervisor> remove
    supervisor> shutdown
    supervisor> status
    supervisor> update
    supervisor> clear
    # 查看supervisor版本
    supervisor> version
    # 退出supervisor控制台
    supervisor> exit 或 quit
    supervisor> maintail
    supervisor> open
    supervisor> signal
