Supervisor 的配置与使用

官网地址：http://supervisord.org/

安装

pip install supervisor

配置

运行 echo_supervisord_conf 命令生成配置

mkdir -p /etc/supervisor/conf.d
echo_supervisord_conf > /etc/supervisor/supervisord.conf

修改配置文件，在文件最后添加

[include]
files = conf.d/*.ini

启动

supervisord -c /etc/supervisor/supervisord.conf

supervisorctl 用法

http://supervisord.org/running.html#running-supervisorctl

supervisorctl status                # 查看进程运行状态
supervisorctl update                # 更新配置，会重启配置改动的进程
supervisorctl reload                # 重载，会重新加载配置，同时重启所有进程
supervisorctl restart all/<name>    # 重启所有或单个进程，重启不会重载配置
supervisorctl stop all/<name>       # 停止进程
supervisorctl clear all/<name>      # 清理日志
supervisorctl tail -f <name>        # 查看日志
