monit被系统杀死后自动重启

Question

我正在使用 monit 来监控我的 WEB 服务。一切正常，直到 monit 进程被系统杀死。监控日志文件的一部分显示了该问题

为了让 monit 在启动时自动启动并在失败时重新启动，我为 monit 添加了 upstart 配置（我是运行 Ubuntu 14.04），看起来像这样：

    # This is an upstart script to keep monit running.
    # To install disable the old way of doing things:
    #
    #   /etc/init.d/monit stop && update-rc.d -f monit remove
    #
    # then put this script here:
    #
    #   /etc/init/monit.conf
    #
    # and reload upstart configuration:
    #
    #   initctl reload-configuration
    #
    # You can manually start and stop monit like this:
    # 
    # start monit
    # stop monit
    #

    description "Monit service manager"

    limit core unlimited unlimited

    start on runlevel [2345]
    stop on starting rc RUNLEVEL=[016]

    expect daemon
    respawn

    exec /usr/bin/monit -c /etc/monitrc

    pre-stop exec /usr/bin/monit -c /etc/monitrc quit

当我重新启动系统时，monit 不是运行。

    sudo monit status
    $ monit: Status not available -- the monit daemon is not running

如何配置 upstart 以保持监控运行和监控？

Answer 1

我在 start monit 命令中的配置文件路径错误。正确的命令是

    exec /usr/bin/monit -c /etc/monit/monitrc

    pre-stop exec /usr/bin/monit -c /etc/monit/monitrc quit

它将 monit 作为守护进程启动，并在我杀死它时重新启动：

    ps aux | grep monit
    root      2173  0.0  0.1 104348  1332 ?        Sl   04:13   0:00 /usr/bin/monit -c /etc/monit/monitrc

    sudo kill -9 2173

    ps aux | grep monit
    root      2184  0.0  0.1 104348  1380 ?        Sl   04:13   0:00 /usr/bin/monit -c /etc/monit/monitrc
