shell> ./bootstrap.sh
shell> ./b2 install

安装后目录

shell> cat /root/.mysql_secret 
# Password set for user 'root@localhost' at 2015-04-22 22:13:23

修改默认密码
shell> bin/mysqladmin -h localhost -u root password '123@qwe' -p'?G5W&tz1z.cN'

另外mysql5.7的mysql.user表结构被修改

修改mysql.user方式修改密码

mysql> update mysql.user set authentication_string=password('123qwe') where user='svoid' and Host = 'localhost';
