#初始化MySQL
[root@mysql01 src]# mysqld --initialize --user mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data

#重置密码为123.com
[root@mysql01 src]# mysql -uroot -p${mysqlpwd} -e 'alter user root@localhost identified by "123.com"' --connect-expired-password
#使用新密码进行登录测试
[root@mysql01 src]# mysql -uroot -p123.com
