在mac上装好nginx环境，想设为开机自动启动。但是linux上的方式不适用于mac。只能利用Mac系统里的Launchctl来做这个事。

1、新建文件

sudo vim /Library/LaunchDaemons/com.nginx.plist

加入

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.nginx.plist</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/local/nginx/sbin/nginx</string>
        </array>
        <key>KeepAlive</key>
        <false/>
        <key>RunAtLoad</key>
        <true/>
        <key>StandardErrorPath</key>
        <string>/usr/local/nginx/logs/error.log</string>
        <key>StandardOutPath</key>
        <string>/usr/local/nginx/logs/access.log</string>
</dict>
</plist>

2、修改权限

sudo chmod 644 /Library/LaunchDaemons/com.nginx.plist


3、注册为系统服务

sudo launchctl load -w /Library/LaunchDaemons/com.nginx.plist 

卸载为sudo launchctl unload -w /Library/LaunchDaemons/com.nginx.plist 

4、重启后查看nginx是否启动

normanygtekimbp:LaunchDaemons normanyang$ ps -ef | grep nginx
    0   169     1   0  3:07下午 ??         0:00.00 nginx: master process /usr/local/nginx/sbin/nginx
    0   170   169   0  3:07下午 ??         0:00.00 nginx: worker process

  501   928   399   0  3:43下午 ttys000    0:00.00 grep nginx

已经启动了，成功！
