Supervisor: 进程管理工具

启动supervisor
supervisord -c supervisord.conf

启动客户端
supervisorctl -c supervisord.conf

客户端内操作进程
> status # 查看程序状态
> stop tornadoes:tornado-8000 # 关闭 程序
> start tornadoes:tornado-8000 # 启动 程序
> restart tornadoes:tornado-8000 # 重启 程序
> reread ＃ 读取有更新（增加）的配置文件，不会启动新添加的程序
> update ＃ 重启配置文件修改过的程序

控制台操作进程
$ supervisorctl status
$ supervisorctl stop tornadoes:tornado-8000 
$ supervisorctl start tornadoes:tornado-8000 
$ supervisorctl restart tornadoes:tornado-8000 
$ supervisorctl reread
$ supervisorctl update

操作步骤
(friend_server_test1) rock1@rock1:~/work/tornado_test/friends_server$ supervisorctl -c supervisord.conf

在项目根目录创建supervisor.conf加入以下内容

[group:tornadoes]　　# 进程组
programs=tornado-8000,tornado-9001　　# 放n个进程

[program:tornado-8000]　　# 如果存在
command=python server.py -runserver -port=8000　　# 执行
directory=/home/pyvip/oasystem　　# 工作目录（此文件（xx.conf）目录）
use=ubuntu
autorestart=true
redirect_stderr=true
stdout_logfile=/home/pyvip/log/oasystem.log  # 日志 tail -f oasystem.log动态查看
loglevel=info

[program:tornado-9001]
command=python server.py -runserver -port=9001
directory=/home/pyvip/oasystem
use=pyvip
autorestart=true
redirect_stderr=true
stdout_logfile=/home/pyvip/log/oasystem.log
loglevel=info

[supervisord]

[supervisorctl]
serverurl=http://192.168.10.128:9999   # 内网ip时192.168.1.102能直接访问9999端口，反而设置的用不了。设置有啥作用？
username=superadmin
password=222

[inet_http_server]
port=:9999
username=superadmin
password=222

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
