brew mysql 安装后进不去(forgot passwor

使用brew安装mysql

w3@mac:~ > brew install mysql

curl: (35) Server aborted the SSL handshake

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

To connect:
    mysql -uroot

To have launchd start mysql at login:
  ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Or, if you don't want/need launchctl, you can just run:
  mysql.server start
==> Summary
🍺  /usr/local/Cellar/mysql/5.7.9: 12629 files, 464M, built in 6.4 minutes

但是使用mysql.server start 启动后使用mysql -uroot提示访问被阻止

解决方案:

mysql.server stop
rm -r /usr/local/var/mysql
mysqld --initialize —user=`whoami` --basedir=/usr/local/Cellar/mysql/5.7.9 --datadir=/usr/local/var/mysql --tmpdir=/tmp

输出的最后一行:

[Note] A temporary password is generated for root@localhost: h;7/yqnxrMaR

冒号后面的就是密码

我们自己的本机不需要这么复杂的密码, 改成简单的密码

mysqladmin -uroot -p password ‘123456'

输入旧的密码后就可以把密码改成123456了

• ps: 安装的密码看看是否则 ~/.mysql_secret
