supervisor备忘

supervisor是把普通app变成deamon的工具，虽然没有erlang的supervise粒度那么细，但是已经非常方便了

 

安装

sudo apt-get install supervisor

 

修改配置文件

sudo gvim /etc/supervisor/supervisord.conf

 

添加下面的以支持web管理

[inet_http_server]
port=9001
username=admin
password=admin

 

新建单独的配置

sudo gvim /etc/supervisor/conf.d/shadowsocks.conf

[program:shadowsocks]
command=/home/mmc/tools/shadowsocks/shadowsocks-local-linux64 -c="/home/mmc/tools/shadowsocks/config.json"
autorestart=true
stdout_logfile=/home/mmc/tools/shadowsocks/supervisor.log

 

supervisor的命令

sudo invoke-rc.d supervisor start
sudo supervisorctl status shadowsocks

 

如果启动的时候报错

 * Starting Supervisor daemon manager...
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 /usr/bin/supervisord -h
   ...fail!

解决办法

sudo find / -name supervisor.sock
sudo unlink /***/supervisor.sock
