mac mysql5.7 不需要密码

mysql 密码错误报错 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) 问题

 

mac 版本5.7    brew 安装  brew reinstall [email protected]

根据输出提示操作：

vim ~/.bash_profile
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

source ~/.bash_profile

/usr/local/opt/[email protected]/bin/mysql.server start

To connect run:
    mysql -uroot

根据提示： mysql -uroot 发现不需要密码即可进入，坑爹啊，半天时间

5.7后版本 观察 安装完毕时 输出提示，有版本输出 随机密码 存于目录下

==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"


To have launchd start [email protected] now and restart at login:
  brew services start [email protected]
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/[email protected]/bin/mysql.server start
