安装配置 Supervisor

在线安装

  • 通过 Setuptools安装

    easy_install supervisor

  • Ubuntu 安装

    sudo apt-get install supervisor

离线安装

注:根据不同的系统,可能需要 root 权限执行安装

配置

    # 生成默认配置
    sudo sh -c '/usr/local/bin/echo_supervisord_conf > /etc/supervisor/supervisor.conf'

    [program:jx-ws]
    command = /bin/bash jx-ws
    directory = /home/${user.home}/opt/jx-ws-shadow-1.0.0/bin
    autostart = true
    autorestart = true
    stdout_logfile = /var/log/ws/out.log
    stdout_logfile_maxbytes = 50MB
    stderr_logfile = /var/log/ws/err.log
    stderr_logfile_maxbytes = 10MB

    说明:

    • 如果启动的程序为 shell,需要在前面增加 /bin/bash
    • directory 设置为可执行程序的上级目录
    • log目录不会自动创建,需手动创建,但是日志文件会自动生成
    • Java 中通过 user.dir获取到的目录为 supervisor 的目录,如需获取程序所在 jar 的运行目录需自行处理
    • 启动需要 root 权限,可通过 sudo supervisord -c /etc/supervisor/supervisor.conf 指定配置路径

运行

  • 启动 sudo supervisord -c /etc/supervisor/supervisor.conf

    -c/--configuration FILENAME -- configuration file path (default /etc/supervisord.conf)
    -h/--help -- print usage message and exit
    -i/--interactive -- start an interactive shell after executing commands

    interactively is started. Use the action "help" to find out about available
    actions.
