Supervisor进程组的使用

说明

因为后端服务一般我们会多开几个服务进程进行API接口的提供，在使用Supervisor进行进程管理的时候，会经常需要对相关进程进行管理。

所以我们可以把同一个相同的所属的进程组进行归类：

创建对应的需要包含的进程配置文件：

[include]
files = /etc/supervisor/config.d/*.ini
[root@web1 etc]# 

示例：

[group:gameserver_data_group]
programs = gameserver_data_consume_all,gameserver_data_consume_all2,gameserver_data_consume_all3,gameserver_data_consume_all4,gameserver_data_consume


[program:gameserver_data_consume_all]
command = /data/www/gameserver_data/venv/bin/python data_consume_all.py              ; the program (relative uses PATH, can take args)
process_name = %(program_name)s      ; process_name expr (default %(program_name)s)
directory = /data/www/gameserver_data      ; directory to cwd to before exec (def no cwd)
stopsignal = QUIT                ; signal used to kill process (default TERM)
stopwaitsecs = 2                 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup = true               ; send stop signal to the UNIX process group (default false)
killasgroup = true               ; SIGKILL the UNIX process group (def false)

[program:gameserver_data_consume_all2]
command = /data/www/gameserver_data/venv/bin/python data_consume_all2.py              ; the program (relative uses PATH, can take args)
process_name = %(program_name)s      ; process_name expr (default %(program_name)s)
directory = /data/www/gameserver_data      ; directory to cwd to before exec (def no cwd)
stopsignal = QUIT                ; signal used to kill process (default TERM)
stopwaitsecs = 2                 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup = true               ; send stop signal to the UNIX process group (default false)
killasgroup = true               ; SIGKILL the UNIX process group (def false)


[program:gameserver_data_consume_all3]
command = /data/www/gameserver_data/venv/bin/python data_consume_all3.py              ; the program (relative uses PATH, can take args)
process_name = %(program_name)s      ; process_name expr (default %(program_name)s)
directory = /data/www/gameserver_data      ; directory to cwd to before exec (def no cwd)
stopsignal = QUIT                ; signal used to kill process (default TERM)
stopwaitsecs = 2                 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup = true               ; send stop signal to the UNIX process group (default false)
killasgroup = true               ; SIGKILL the UNIX process group (def false)


[program:gameserver_data_consume_all4]
command = /data/www/gameserver_data/venv/bin/python data_consume_all4.py              ; the program (relative uses PATH, can take args)
process_name = %(program_name)s      ; process_name expr (default %(program_name)s)
directory = /data/www/gameserver_data      ; directory to cwd to before exec (def no cwd)
stopsignal = QUIT                ; signal used to kill process (default TERM)
stopwaitsecs = 2                 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup = true               ; send stop signal to the UNIX process group (default false)
killasgroup = true               ; SIGKILL the UNIX process group (def false)


[program:gameserver_data_consume]
command = /data/www/gameserver_data/venv/bin/python data_consume.py              ; the program (relative uses PATH, can take args)
process_name = %(program_name)s      ; process_name expr (default %(program_name)s)
directory = /data/www/gameserver_data      ; directory to cwd to before exec (def no cwd)
stopsignal = QUIT                ; signal used to kill process (default TERM)
stopwaitsecs = 2                 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup = true               ; send stop signal to the UNIX process group (default false)
killasgroup = true               ; SIGKILL the UNIX process group (def false)

管理命令：

停止组（需要带上冒号）：
supervisor> stop gameserver_data_group:
也可以具体到某个进程：
supervisor> stop gameserver_data_group:gameserver_data_consume_all 
也可以使用*号：
supervisor> restart gameserver_data_group: *
