Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!
我第一次用sudo mysqld start启动的时候,报错是上面那个,我查了一下stackoverflow发现,mac下的启动要用mysql.server 那个命令
但是我之后使用sudo mysql.server那个命令,又报错
[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it. 2014-01-31 00:03:03 13223 [Note] InnoDB: The InnoDB memory heap is disabled
查了一下,发现是文件权限问题
