; Sample supervisor config file.

[unix_http_server]
file=/etc/supervisor/supervisor.sock   ; (the path to the socket file)

[supervisord]
logfile=/var/log/supervisord.log  ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10          ; (num of main logfile rotation backups;default 10)
loglevel=info               ; (log level;default info; others: debug,warn,trace)
pidfile=/etc/supervisor/supervisord.pid ; (supervisord pidfile;default supervisord.pid)

minprocs=4096               ; (min. avail process descriptors;default 200)


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

[supervisorctl]
serverurl=unix:///etc/supervisor/supervisor.sock ; 默认是配置在 /tmp 目录下，避免长时间未使用导致文件被删除，建议修改为 /etc/superviosr的目录下


[include]
files = /home/workspace/*/shell/supervisor.conf ;默认加载路径可以自己定义

sudo vi /etc/supervisor/conf.d/myapp.conf

[program:myapp]
command=/usr/bin/java -jar /path/to/myapp.jar  # 替换为你的命令
directory=/path/to/                          # 工作目录（可选）
user=root                                    # 运行用户（可选）
autostart=true                               # 随 Supervisor 启动
autorestart=true                             # 崩溃时自动重启
stderr_logfile=/home/logs/appname/myapp.err.log        # 错误日志
stdout_logfile=/home/logs/appname/myapp.out.log        # 输出日志
environment=HOME="/home/user",USER="user"    # 环境变量（可选）

sudo supervisord -c /etc/supervisord.conf
# 或
sudo supervisorctl reread
sudo supervisorctl update

# 查看所有进程状态
sudo supervisorctl status

# 启动/停止/重启某个进程
sudo supervisorctl start myapp
sudo supervisorctl stop myapp
sudo supervisorctl restart myapp

# 重新加载所有配置（新增/修改配置后）
sudo supervisorctl reread
sudo supervisorctl update

# 查看日志
sudo supervisorctl tail myapp stderr  # 查看错误日志
sudo supervisorctl tail myapp stdout  # 查看输出日志

sudo systemctl enable supervisord

sudo systemctl stop supervisord
sudo yum remove supervisor
sudo rm -rf /etc/supervisor /var/log/supervisor

sudo systemctl stop supervisord
sudo apt purge supervisor
