初始化數據庫ui

/usr/local/mysql/bin/mysqld --defaults-file=/data/3307/my.cnf --user=mysql --basedir=/usr/local/mysql --datadir=/data/3307/data --initialize.net

ps：該步驟會生成root帳戶密碼code

啓動實例orm

/usr/local/mysql/bin/mysqld --defaults-file=/data/3307/my.cnf --user=mysqlserver

登陸

mysql -S /data/3307/mysql.sock -p

修改密碼

set password for root@localhost = password('123');

受權遠程訪問

grant all privileges on *.* to 'root'@'%' identified by '123' with grant option; flush privileges;
