Supervisor基础
常识
Supervisor（http://supervisord.org/）是用Python开发的一个client/server服务，是Linux/Unix系统下的一个进程管理工具，不支持Windows系统。它可以很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程，当一个进程意外被杀死，supervisort监听到进程死后，会自动将它重新拉起，很方便的做到进程自动恢复的功能，不再需要自己写shell脚本来控制

以tomcat 举例
Tomcat进程的一个例子： [program:tomcat] command=/opt/apache-tomcat-8.0.35/bin/catalina.sh run stdout_logfile=/opt/apache-tomcat-8.0.35/logs/catalina.out autostart=true autorestart=true startsecs=5 priority=1 stopasgroup=true killasgroup=true bash终端 supervisorctl status supervisorctl stop tomcat supervisorctl start tomcat supervisorctl restart tomcat supervisorctl reread supervisorctl update 开机启动Supervisor服务 7.1 配置systemctl服务 1> 进入/lib/systemd/system目录，并创建supervisor.service文件 [Unit] Description=supervisor After=network.target [Service] Type=forking ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown ExecReload=/usr/bin/supervisorctl $OPTIONS reload KillMode=process Restart=on-failure RestartSec=42s [Install] WantedBy=multi-user.target 2> 设置开机启动 systemctl enable supervisor.service systemctl daemon-reload 3、修改文件权限为766 chmod 766 supervisor.service
trouble shooting
求助！supervisord 报错 FATAL Exited too quickly (process log may have details)
entered FATAL state, too many start retries too quickly
我 user 改成 root 之后可以了
