如何在mac上自动启动php fpm

我想在我的mac（Yosemite10.10.5）上安装nginx和php。但是当我重新启动mac时，php fpm无法自动启动。

步骤1，通过brew安装nginx

==>如果成功，我可以访问

步骤2，设置nginx服务自动启动，如下所示

sudo chown root:wheel/usr/local/opt/nginx/bin/nginx
sudo chmod u+s/usr/local/opt/nginx/bin/nginx
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/nginx/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/

sudo chown root:wheel /usr/local/opt/php54/sbin/php-fpm
sudo chmod u+s /usr/local/opt/php54/sbin/php-fpm
cp /usr/local/opt/php54/homebrew.mxcl.php54.plist ~/Library/LaunchAgets

步骤3，测试自动启动功能，参见图

=>成功

步骤4，通过brew安装php5.4

=>成功

步骤4，设置php54自动启动，如下所示

sudo chown root:wheel/usr/local/opt/nginx/bin/nginx
sudo chmod u+s/usr/local/opt/nginx/bin/nginx
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/nginx/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/

sudo chown root:wheel /usr/local/opt/php54/sbin/php-fpm
sudo chmod u+s /usr/local/opt/php54/sbin/php-fpm
cp /usr/local/opt/php54/homebrew.mxcl.php54.plist ~/Library/LaunchAgets

步骤5，测试自动启动功能

==>失败，什么也没发生。请看图片。

第六步，我想这是权限问题，所以我键入了follow和success

sudo launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php54.plist

因此，我作为nginx执行了步骤4以避免权限问题，但结果失败。任何帮助都将不胜感激
