Osx:Percona安装

brew install percona-server

安装完会有提示：

A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

MySQL is configured to only allow connections from localhost by default

To connect:
    mysql -uroot

To initialize the data directory:
    mysqld --initialize --datadir=/usr/local/var/mysql --user=hfli

To have launchd start percona-server now and restart at login:
  brew services start percona-server
Or, if you don't want/need a background service you can just run:
  mysql.server start

一定要按照提示执行一下：

mysqld --initialize --datadir=/usr/local/var/mysql --user=hfli
mysql.server start

很可惜不知道安装完的默认密码是多少，日志也没有找到，所以只能去改一下密码了，参考MySQL:忘记root密码
