oracle收購Mysql后，Mysql的安裝配置方法

現在在oracle官網上下載的mysql有以下幾個rpm包

MySQL-client-advanced

MySQL-devel-advanced

MySQL-embedded-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-server-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-shared-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-shared-compat-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-test-advanced-5.6.14-1.rhel5.x86_64.rpm

1、先把系統里安裝的所有mysql找出來

#rpm -qa | grep -i mysql 運行此命令后，顯示所有列表：

mysqlclient10-3.23.58-4.RHEL4.1

mysqlclient10-devel-3.23.58-4.RHEL4.1

2、將列表一一強制刪除：

#rpm -ev --nodeps mysqlclient10-3.23.58-4.RHEL4.1

#rpm -ev --nodeps mysqlclient10-devel-3.23.58-4.RHEL4.1

3、將老版本的幾個文件手工刪除：

#rm -f /etc/my.cnf

#rm -rf /var/lib/mysql

#rm -rf/var/share/mysql

# rm -rf/usr/bin/mysql*

4.安裝下載的版本的mysql,如上,

[root@oracle11 ~]#rpm -ivh MySQL-server-advanced-5.6.14-1.el6.x86_64.rpm

Preparing... ########################################### [100%]

1:MySQL-server-advanced ###########################################[100%]

5.安裝client

[root@oracle11 ~]#rpm -ivh MySQL-client-advanced-5.6.14-1.el6.x86_64.rpm

Preparing... ########################################### [100%]

1:MySQL-client-advanced ###########################################[100%]

說明:不安裝mysql-client是不能使用mysql工具登陸到mysql數據庫

6.oracle收購Mysql后,新版的mysql剛安裝完mysql后不能直接輸入mysql登錄數據庫,而是設置了默認free password密碼,默認密碼放在了/root/.mysql_secret文件中,登陸后需要修改密碼

安裝完成后有這么一段話,

A RANDOMPASSWORD HAS BEEN SET FOR THE MySQL root USER !

You willfind that password in '/root/.mysql_secret'.

You must change thatpassword on your first connect,

no other statementbut 'SET PASSWORD' will beaccepted.

See the manual forthe semantics of the 'password expired' flag.

Also, the accountfor the anonymous user has been removed.

In addition, you canrun:

/usr/bin/mysql_secure_installation

which will also giveyou the option of removing the test database.

This is stronglyrecommended for production servers.

See the manual formore instructions.

Please report anyproblems with the /usr/bin/mysqlbug script!

The latestinformation about MySQL is available on the web at

http://www.mysql.com

Support MySQL bybuying support/licenses at http://shop.mysql.com

New default configfile was created as /usr/my.cnf and

will be used bydefault by the server when you start it.

You may edit thisfile to change server settings

7.修改密碼

(1)查看文件尋找密碼

[root@oracle11 ~]#vi /root/.mysql_secret

# The randompassword set for the root user at Mon Oct 28 11:09:39 2013 (local time): 3eriwUfI

(2)登陸Mysql

[root@oracle11 ~]#mysql -u root -p

Enter password:

Welcome to the MySQLmonitor. Commands end with ; or /g.

Your MySQLconnection id is 3

mysql>

(3)修改密碼

mysql> setpassword for 'root'@'localhost' = password ('root');

Query OK, 0 rowsaffected (0.05 sec)

當然也可以使用腳本 /usr/bin/mysql_secure_installation進行交互式的修改mysql的root密碼，如下：

[root@oracle11 ~]# /usr/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current

password for the root user. If you've just installed MySQL, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

Set root password? [Y/n] y

New password:

Re-enter new password:

Password updated successfully!

Reloading privilege tables..

... Success!

By default, a MySQL installation has an anonymous user, allowing anyone

to log into MySQL without having to have a user account created for

them. This is intended only for testing, and to make the installation

go a bit smoother. You should remove them before moving into a

production environment.

Remove anonymous users? [Y/n] n

... skipping.

Normally, root should only be allowed to connect from 'localhost'. This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n

... skipping.

By default, MySQL comes with a database named 'test' that anyone can

access. This is also intended only for testing, and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n] n

... skipping.

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n] n

... skipping.

All done! If you've completed all of the above steps, your MySQL

installation should now be secure.

Thanks for using MySQL!
