mysql -u mysql -p -S /var/lib/mysql/mysql.sock 1、先把系統(tǒng)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： linux-hueu:/ # rpm -qa | grep -i mysql libmysqld18-5.5.33-2.2.x86_64 libmysqlcppconn6-1.1.2-4.1.3.x86_64 libqt4-sql-mysql-4.8.5-5.9.2.x86_64 MySQL-client-advanced-5.6.18-1.sles11.x86_64 libreoffice-base-drivers-mysql-4.1.5.3-17.1.x86_64 libmysqlclient18-5.5.33-2.2.x86_64 MySQL-server-advanced-5.6.18-1.sles11.x86_64 2、將列表一一強制刪除： 卸載順序： [root@bakdbserver ~]# rpm -e MySQL-server-5.5.24-1.rhel5 [root@bakdbserver ~]# rpm -e MySQL-embedded-5.5.24-1.rhel5 [root@bakdbserver ~]# rpm -e MySQL-shared-5.5.24-1.rhel5 [root@bakdbserver ~]# rpm -e MySQL-devel-5.5.24-1.rhel5 [root@bakdbserver ~]# rpm -e MySQL-test-5.5.24-1.rhel5 [root@bakdbserver ~]# rpm -e MySQL-client-5.5.24-1.rhel5 #rpm -ev --nodeps MySQL-server-advanced-5.6.18-1.sles11.x86_64 #rpm -ev --nodeps MySQL-client-advanced-5.6.18-1.sles11.x86_64 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-client-advanced-5.6.18-1.sles11.x86_64.rpm linux-hueu:/home/yangbing/soft/Mysql # rpm -ivh MySQL-server-advanced-5.6.18-1.sles11.x86_64.rpm[root@oracle11 ~]#rpm -ivh MySQL-server-advanced-5.6.18-1.sles11.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:MySQL-server-advanced-5.6.18-1.sl################################# [100%] Note: This output shows SysV services only and does not include native systemd services.

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. See the manual for more instructions. Please report any problems at http://bugs./ The latest information about MySQL is available on the web at http://www. Support MySQL by buying support/licenses at http://shop. WARNING: Found existing config file /usr/my.cnf on the system. Because this file might be in use, it was not replaced, but was used in bootstrap (unless you used --defaults-file) and when you later start the server. The new default config file was created as /usr/my-new.cnf, please compare it with your file and take the changes you need. 7.重啟計算機 8.修改密碼 (1)查看文件尋找密碼 linux-hueu:~ # more .mysql_secret # The random password set for the root user at Sun Jun 15 22:12:23 2014 (local t ime): kg0F19KJRWcTPLU6 (2)登陸Mysql

Query OK, 0 rowsaffected (0.05 sec)
當(dāng)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!
