1、brew安装MySQL
// 1. 若不考虑版本直接执行以下命令
brew install mysql
// 2. 若要选择版本只要加上@版本即可，例如
brew install mysql@5.7
// 3. 安装完后启动mysql
brew services start mysql@5.7
// 4. 若服务未启动就会出现以下错误
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
// 5. 若要关闭mysql
brew services stop mysql@5.7
// 6. 看到提示success则表示启动成功
Starting MySQL
. SUCCESS!
// 7. 现在登录mysql,默认情况下免密登录
mysql -u root
// 8. 修改root密码，这是5.7的修改方法
alter user 'root'@'localhost' identified with mysql_native_password by 'root';
// 9. 回车后有提示，则表示修改成功
Query OK, 0 rows affected (0.00 sec)
// 10. 接着退出mysql
exit;
// 11. 最后重新登录
mysql -u root -p
提示信息
// 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
// mysql@5.7 is keg-only, which means it was not symlinked into /opt/homebrew,
// because this is an alternate version of another formula.
// If you need to have mysql@5.7 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/mysql@5.7/bin:$PATH"' >> ~/.zshrc
// For compilers to find mysql@5.7 you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/mysql@5.7/lib"
export CPPFLAGS="-I/opt/homebrew/opt/mysql@5.7/include"
// For pkg-config to find mysql@5.7 you may need to set:
export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql@5.7/lib/pkgconfig"
// To start mysql@5.7 now and restart at login:
brew services start mysql@5.7
