致此mysql安装完成，期间碰到目录不存在的则自行创建目录。

尝试下mysql是否能正常启动和停止：

root@iZ23k28j4i8Z:/home/mysql#
service mysql start

Starting MySQL

.. *

root@iZ23k28j4i8Z:/home/mysql#
netstat -tnl|grep 3306tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN

root@iZ23k28j4i8Z:/home/mysql#
service mysql stopShutting down MySQL. *

看到了吧，mysql可以正常启动和停止了。

不过还没结束哦

增加链接：

ln
-s /home/mysql/bin/mysql /usr/binln -s /home/mysql/bin/mysqladmin /usr/bin

为root用户设置密码：

/home/mysql/bin/mysqladmin
-u root password '******'

用root登录mysql：

root@iZ23k28j4i8Z:/home/mysql#
mysql -uroot -p******Welcome to the MySQL monitor.

登录mysql后执行以下三条命令：

mysql> GRANT
ALL PRIVILEGES ON *.* TO root

mysql> GRANT
ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY "密码"

mysql> GRANT
ALL PRIVILEGES ON *.* TO root IDENTIFIED BY "密码"

这样就可以用客户端工具以root及密码登录了。

如果有乱码则可以尝试以下解决方式：

修改/etc/my.cnf

[mysqld]在这里添加以下3行

character-set-server=utf8collation-server = utf8_unicode_ciinit_connect = 'set collation_connection = utf8_unicode_ci;'
