官网：

macOS使用launchctl命令加载开机自动运行的服务，brew service可以简化lauchctl的操作。

以MySQL为例，使用launchctl启动:

ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

如使用brew service可以简化为:

brew services start mysql

常用命令

brew services list  # 查看使用brew安装的服务列表
brew services run formula|--all  # 启动服务（仅启动不注册）
brew services start formula|--all  # 启动服务，并注册
brew services stop formula|--all   # 停止服务，并取消注册
brew services restart formula|--all  # 重启服务，并注册
brew services cleanup  # 清除已卸载应用的无用的配置

配置文件目录

/Library/LaunchDaemons # 开机自启，需要sudo
~/Library/LaunchAgents # 用户登录后自启

以homebrew.mxcl.kafka.plist为例：

<?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>homebrew.mxcl.kafka</string>
    <key>WorkingDirectory</key>
    <string>/usr/local</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/opt/kafka/bin/kafka-server-start</string>
        <string>/usr/local/etc/kafka/server.properties</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
    <key>StandardErrorPath</key>
    <string>/usr/local/var/log/kafka/kafka_output.log</string>
    <key>StandardOutPath</key>
    <string>/usr/local/var/log/kafka/kafka_output.log</string>
</dict>
</plist>

在这里可以找到服务路径、启动参数、日志路径等
