Supervisor官网：[http://supervisord.org/][http_supervisord.org]

1.安装supervisor

#pip
    pip install supervisor
    
    #ubuntu
    sudo apt-get install supervisor
    
    #centos
    yum -y install supervisor

2.启动，安装完后如supervisor没启动，可以使用如下，手动启动

#启动supervisor
    /usr/bin/supervisord -c /etc/supervisord.conf

3.添加开机自启动

#创建supervisord.service
    vi /usr/lib/systemd/system/supervisord.service
    
    #supervisord.service文件内容
    [Unit]
    Description=Supervisor
    
    [Service]
    Type=forking
    ExecStart=/usr/bin/supervisord -c /etc/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

#激活开机启动
    systemctl enable supervisord.service
    
    #如修改了supervisord.service配置文件需重新加载
    systemctl daemon-reload

4.创建一个应用程序spring-app的配置文件

[program:spring-app]
    command=java -Djava.awt.headless=true -Xms512M -Xmx1G -Dfile.encoding=UTF8 -Dspring.profiles.active=prod -jar /var/lib/spring/spring-app.jar
    user=spring
    group=spring
    
    autostart=true
    autorestart=true
    startretries=3
    stdout_logfile=/dev/null
    redirect_stderr=true
    stderr_logfile=/var/log/spring/spring-app.err
    stderr_logfile_maxbytes=100MB
    stderr_logfile_backups=2

#加载配置文件
    supervisorctl reread
    
    #启动spring-app
    supervisorctl start spring-app
    
    #查看进程状态
    supervisorctl status
