Question

我使用的是MacPorts生态系统，而rabbitmq-server端口真的很旧，而且它不再起作用了。所以我使用Generic Unix release在Mac OS X Sierra上安装了rabbitmq-server。它有效。

RabbitMQ安装在/usr/local/rabbitmq_server-3.6.5/下，/usr/local/sbin/下的所有可执行文件都有符号链接。

ls -al

drwxr-xr-x  7 root  wheel  238 Sep 24 19:50 .
drwxr-xr-x  8 root  wheel  272 Sep 24 19:30 ..
lrwxr-xr-x  1 root  wheel   55 Sep 24 19:50 rabbitmq-defaults -> /usr/local/rabbitmq_server-3.6.5/sbin/rabbitmq-defaults
lrwxr-xr-x  1 root  wheel   50 Sep 24 19:50 rabbitmq-env -> /usr/local/rabbitmq_server-3.6.5/sbin/rabbitmq-env
lrwxr-xr-x  1 root  wheel   54 Sep 24 19:50 rabbitmq-plugins -> /usr/local/rabbitmq_server-3.6.5/sbin/rabbitmq-plugins
lrwxr-xr-x  1 root  wheel   53 Sep 24 19:50 rabbitmq-server -> /usr/local/rabbitmq_server-3.6.5/sbin/rabbitmq-server
lrwxr-xr-x  1 root  wheel   49 Sep 24 19:50 rabbitmqctl -> /usr/local/rabbitmq_server-3.6.5/sbin/rabbitmqctl

当我运行RabbitMQ服务器时，一切都按预期工作：

sudo rabbitmq-server

为了自动启动守护程序，我创建了一个com.rabbitmq.rabbitmq-server.plist文件/usr/local/etc/LaunchDaemons。我还在/Library/LaunchDaemons中为此文件创建了一个符号链接。所有者为root，该群组为wheel。

以下是plist文件内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>KeepAlive</key>
  <true/>
  <key>Label</key>
  <string>com.rabbitmq.rabbitmq-server</string>
  <key>ProgramArguments</key>
  <array>
    <string>/usr/local/sbin/rabbitmq-server</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>EnvironmentVariables</key>
  <dict>
    <key>PATH</key>
    <string>/usr/local/sbin:/usr/bin:/bin:/usr/local/bin</string>
  </dict>
</dict>
</plist>

当我尝试使用

加载plist文件时

sudo launchctl load -w /Library/LaunchDaemons/com.rabbitmq.rabbitmq-server.plist

我没有收到任何错误，但守护程序无法启动。我甚至尝试将调试信息添加到plist，但日志不会显示任何错误。我做错了什么？

嗯，这并不容易，但我终于找到了解决方案。

这是最终的com.rabbitmq.rabbitmq-server.plist脚本：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.rabbitmq.rabbitmq-server</string>
  <key>ProgramArguments</key>
  <array>
    <string>/opt/local/bin/daemondo</string>
    <string>--label=rabbitmq-server</string>
    <string>--start-cmd</string>
    <string>/usr/local/sbin/rabbitmq-server</string>
    <string>-u</string>
    <string>nobody</string>
    <string>;</string>
    <string>--pid=exec</string>
  </array>
  <key>Disabled</key><true/>
  <key>RunAtLoad</key><true/>
  <key>KeepAlive</key><true/>
  <key>EnvironmentVariables</key>
  <dict>
    <key>HOME</key>
    <string>/usr/local/rabbitmq_server-3.6.5</string>
    <key>PATH</key>
    <string>/usr/local/sbin:/usr/bin:/bin:/usr/local/bin:/opt/local/bin:/opt/local/sbin:/usr/local/rabbitmq_server-3.6.5/sbin</string>
  </dict>
  <key>StandardOutPath</key>
  <string>/var/log/rabbit-launchd.log</string>
  <key>StandardErrorPath</key>
  <string>/var/log/rabbit-launchd-error.log</string>
</dict>
</plist>

我使用了MacPorts中的daemondo来运行rabbitmq-server可执行文件。比我更新了PATH变量。使用StandardErrorPath我已经发现ErLang无法找到可执行的主目录：事实上我得到了这个错误：

erlexec: HOME must be set

所以我已将HOME添加到EnvironmentVariables部分。

如果您在MacPorts上进行中继而不使用Homebrew，则可以使用此脚本使用launchd运行RabbitMQ服务器并安装Generic Unix版本。

RabbitMQ没有开始使用launchd
