Linux上安装MySQL5.6
OS & MySQL的版本号和配置：
MySQL Version: 5.6.19
Linux Version: Linux boston.oracle.com 2.6.18-164.el5 #1 SMP Thu Sep 3 02:16:47 EDT 2009 i686 i686 i386 GNU/Linux
一。下载MySQL安装软件。请到www.oracle.com 去找DATABASE DOWNLOAD。下载MySQL须要注冊一个账号。
我下载的版本号例如以下：
下载后解压就是下面的8个文件 ：
二， 在Linux上安装MySQL(一个server程序和一个client程序)

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:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
/* 上面的红色的大概意思例如以下：
为MySQL的数据库的root的用户生成了一个随机的秘密，请到/root/.mysql_secret里去找password。
当你第一次登陆时必须改动password，同一时候匿名帐号已经被删除掉了。
除此之外，你能够运行：
/usr/bin/mysql_secure_installation
他能够给你一些移除test 数据库的选项。
强烈推荐在生产server上做此操作。
*/
See the manual for more instructions.

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
--安装Client端：
[root@vmoel5u4 mysql_installer]# rpm -ivh MySQL-client-advanced-5.6.19-1.rhel5.i386.rpm

三，MySQL 数据库的配置
1。启动MySQL服务
[root@vmoel5u4 mysql_installer]# cd /etc/rc.d/init.d
[root@vmoel5u4 init.d]# service mysql start
Starting MySQL.......... [ OK ]
2。改动MySQL数据库root用户的初始password，先查下初始password
[root@vmoel5u4 mysql_installer]# vi /root/.mysql_secret
# The random password set for the root user at Sun Nov 18 00:34:51 2012 (local time): kX65UtYvovXN9VOV
从上面能够初始password是：kX65UtYvovXN9VOV
[root@vmoel5u4 init.d]# mysql -uroot -p
Enter password:

mysql>
/*改动password为123456*/
mysql> update user set password=PASSWORD('123456') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
/*刷新权限表*/
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
3。用新password123456登陆MySQL
[root@vmoel5u4 init.d]# mysql -uroot -p
Enter password:

mysql> use mysql ;

You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select Host,User,Password from user;
+-----------+------+-------------------------------------------+
| Host | User | Password |
+-----------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+-----------+------+-------------------------------------------+
3 rows in set (0.00 sec)
4, 创建新的表test,并插入測试数据
mysql> create table test(id int);
Query OK, 0 rows affected (0.05 sec)
mysql> insert into test(id) values(1);
Query OK, 1 row affected (0.05 sec)
mysql> insert into test(id) values(2);
Query OK, 1 row affected (0.01 sec)
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql> select * from test;
+------+
| id |
+------+
| 1 |
| 2 |
+------+
2 rows in set (0.02 sec)
四，MySQL通过RPM包安装后的路径布局
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
From MySQL5.6 version, During RPM installation, a user named mysql and a group named mysql are created on the system. This is done using the useradd, groupadd, and usermod commands. Those commands require appropriate administrative privileges, which is required for locally managed users and groups (as listed in the /etc/passwd and /etc/group files) by the RPM installation process being run by root.
安装5.6版本号的MySQL的时候，RPM安装包会自己主动的创建mysql 组合mysql用户。
创建mysql的CDDL数据库的新用户watson
use mysql
mysql>create user
'watson'@'172.30.41.93' identified by 'watson';
mysql>grant all on cddl.* to
'watson'@'172.30.41.93';
