mac 启动mysql Error: Failure while executing； `/bin/launchctl bootstrap gui/501

Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users//Library/LaunchAgents/homebrew.mxcl.mysql@8.0.plist` exited with 5.

查看 homebrew.mxcl.mysql@8.0.plist文件，能看到具体的启动命令

	KeepAlive
	
	Label
	homebrew.mxcl.mysql@8.0
	LimitLoadToSessionType
	
		Aqua
		Background
		LoginWindow

		--datadir=/usr/local/var/mysql
	
	RunAtLoad
	
	WorkingDirectory
	/usr/local/var/mysql

然后直接用/usr/local/opt/mysql@8.0/bin/mysqld_safe命令启动，看到具体报错信息，提示权限不够，发现有个文件夹用户组不对，改下用户组就好了
