A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'. You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!
The latest information about MySQL is available on the web at
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
需要注意的几个文件：'/root/.mysql_secret'存有初始密码；/usr/my.cnf为配置文件
安装client
rpm -ivh MySQL-client-5.6.11-1.rhel5.x86_64.rpm

安装devep包
rpm -ivh MySQL-devel-5.6.11-1.rhel5.x86_64.rpm

3. 重要的文件及目录
[root@localhost mysql]# whereis mysql
mysql: /usr/bin/mysql
/var/lib/mysql/
（2）配置文件
/usr/share/mysql（mysql.server命令及配置文件）
（3）相关命令
（4）启动脚本
/etc/rc.d/init.d/（mysql文件，启动脚本文件mysql的目录）
| Directory | Contents of Directory |
|---|---|
| /usr/bin | Client programs and scripts |
| /usr/sbin | The mysqld server |
| /var/lib/mysql | Log files, databases |
| /usr/share/info | Manual in Info format |
| /usr/share/man | Unix manual pages |
| /usr/include/mysql | Include (header) files |
| /usr/lib/mysql | Libraries |
| /usr/share/mysql | Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation |
| /usr/share/sql-bench | Benchmarks |
4. 启动mysql（普通用户也行）
service mysql start
或者
/etc/init.d/mysql
Starting MySQL.The server quit without updating PID file (/[澶辫触]mysql/localhost.pid).
启动 停止、重启命令
mysql: /etc/init.d/mysql start|stop|restart
5. 登录MySQL
登录MySQL的命令是mysql， mysql 的使用语法如下：
mysql [-u username] [-h host] [-p[password]] [dbname]
username 与 password 分别是 MySQL 的用户名与密码，mysql的初始管理帐号是root，密码，在文件~/mysql_secret中，注意：这个root用户不是Linux的系统用户。MySQL默认用户是root。
在修改密码之前，什么也做不了。使用mysqladmin修改密码
[root@localhost mysql]# /usr/bin/mysqladmin -u root -p文件中的密码 password 新密码
成功的话，会出现如下的提示：
Warning: Using a password on the command line interface can be insecure.
==================================
到目前，mysql应该装好了，登陆进去，使用 show databases； 或者 show tables；测试下
mysql> show databases;
