d. 初始化MySQL及设置密码

1
[root@localhost rpm]# /usr/bin/mysql_install_db

2
[root@localhost rpm]# service mysql start

3
[root@localhost rpm]# cat /root/.mysql_secret  #查看root账号密码

4

5
[root@localhost ~]# mysql -uroot –pqKTaFZnl

6
mysql> SET PASSWORD = PASSWORD('123456');    #设置密码为123456

7
mysql> exit

8
[root@localhost ~]# mysql -uroot -p123456

e. 远程登陆用户设置

01
mysql> use mysql;

14
mysql> flush privileges;
