status marybaked 产量

marybaked 停止/等待

这是/var/log/syslog 的输出：

5 月 3 日 16:24:39 marybakedpdx 内核：[3464.189563] init：无法生成 marybakedpdx 主进程：找不到 setuid 用户

5 月 3 日 16:24:44 marybakedpdx 内核：[3469.342062] init：无法生成 marybaked 主进程：无法找到 setuid 用户

当我运行start marybaked 时，我得到：

启动：作业启动失败

当我运行start <anything else> 时，我得到：

开始：未知工作：

我的/var/logs/upstart 目录中没有marybaked.log 日志...这是怎么回事？ upstart 怎么能认出marybaked 是一个job，启动失败，却没有为它创建错误日志？

这是我的/etc/init/marybaked.conf 文件：

# upstart service file at /etc/init/marybakedpdx.conf
    description "Meteor.js (NodeJS) application"
    author "Daniel Speichert <daniel@speichert.pro>"

    # When to start the service
    start on started mongodb and runlevel [2345]

    # When to stop the service
    stop on shutdown

    # Automatically restart process if crashed
    respawn
    respawn limit 10 5

    # we don't use buil-in log because we use a script below
    # console log

    # drop root proviliges and switch to mymetorapp user
    setuid marybakedpdx
    setgid marybakedpdx

    end script

您的新贵文件看起来不错，最有可能发生的是您的 script 块中的某些内容失败了。应该在syslog中详细说明。

尝试查看/var/log/syslog

为了进一步调试，您还应该在各个点尝试touch 文件，以进一步缩小问题范围。例如：

touch /tmp/marybake0
exec node /home/marybakedpdx/bundle/main.js >> /home/marybakedpdx/marybakedpdx.log

如果文件不存在，touch 将创建该文件。
