MySQL服务管理
MAC OS安装
我们直接下载PKG安装包进行安装，按官方说法是10.2版本开始有pkg安装包，实际也只有10.2.x版本存在，https://downloads.mariadb.com/MariaDB/
下载后直接安装即可，会自动安装在/usr/local/mariadb/中
配置文件在
/usr/local/etc/my.cnf
/usr/local/etc/my.cnf.default
/usr/local/etc/my.cnf.d/
/usr/local/mariadb/etc/my.cnf
安装完成后用 sudo /usr/local/mariadb/server/bin/mysql_secure_installation初始化数据库，一定要用sudo提权
MariaDB默认绑定到127.0.0.1，并禁用了TCP连接，需要将其关闭
关闭仅限本地访问：
sudo vi /usr/local/etc/my.cnf.default
注释掉bind-address
启用网络连接：
sudo vi /usr/local/mariadb/etc/my.cnf
注释掉skip-networking
启动时提示无法用root启用，加上--user=mysql即可
select user();#查看当前登录用户
授权用户远程登录：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456.Com' WITH GRANT OPTION;
flush privileges;刷新授权表
mysql -uroot -p -h 127.0.0.1 -P 3306;指定mysql客户端登录指定服务器
密码破解修改：
统一字符编码：
登录后用\s查看字符编码
mysql> \s
