OS & MySQL的版本號和配置：

MySQL Version: 5.6.19Linux 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。下載MySQL安裝軟件。請到www.oracle.com去找DATABASE DOWNLOAD。下載MySQL須要注冊一個賬號。

我下載的版本號例如以下：

下載后解壓就是下面的8個文件 ：

二， 在Linux上安裝MySQL(一個server程序和一個client程序)

[root@vmoel5u4 mysql_installer]# ll

-rw-r--r-- 1 root root 22925106 May? 8? 2014 MySQL-client-advanced-5.6.19-1.rhel5.i386.rpm

-rw-r--r-- 1 root root 95621549 May? 8? 2014 MySQL-server-advanced-5.6.19-1.rhel5.i386.rpm

--安裝Server端：

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.

/*? 上面的紅色的大概意思例如以下：

為MySQL的數據庫的root的用戶生成了一個隨機的秘密，請到/root/.mysql_secret里去找password。

當你第一次登陸時必須改動password，同一時候匿名帳號已經被刪除掉了。

除此之外，你能夠運行：

/usr/bin/mysql_secure_installation

他能夠給你一些移除test 數據庫的選項。

強烈推薦在生產server上做此操作。

*/

See the manual for more instructions.

Please report any problems athttp://bugs.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

--安裝Client端：

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

三，MySQL 數據庫的配置

1。啟動MySQL服務

[root@vmoel5u4 mysql_installer]# cd /etc/rc.d/init.d

[root@vmoel5u4 init.d]# service mysql start

Starting MySQL..........?????????????????????????????????? [? OK? ]

2。改動MySQL數據庫root用戶的初始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

從上面能夠初始password是：kX65UtYvovXN9VOV

[root@vmoel5u4 init.d]# mysql -uroot -p

Enter password:

Welcome to the MySQL monitor.? Commands end with ; or \g.

Your MySQL connection id is 15

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

/*改動password為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

/*刷新權限表*/

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

3。用新password123456登陸MySQL

[root@vmoel5u4 init.d]# mysql -uroot -p

Enter password:

Welcome to the MySQL monitor.? Commands end with ; or \g.

Your MySQL connection id is 16

Server version: 5.6.19-enterprise-commercial-advanced MySQL Enterprise Server - Advanced Edition (Commercial)

Copyright (c) 2000, 2014, Oracle and/or its affiliates. All rights reserved.

owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> use mysql ;

Reading table information for completion of table and column names

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 |

| 127.0.0.1 | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| ::1?????? | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+-----------+------+-------------------------------------------+

3 rows in set (0.00 sec)

4, 創建新的表test,并插入測試數據

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通過RPM包安裝后的路徑布局

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.

安裝5.6版本號的MySQL的時候，RPM安裝包會自己主動的創建mysql 組合mysql用戶。

創建mysql的CDDL數據庫的新用戶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';
