首先我們需要先用下面的命令安裝MySQL5：
yast2 -i mysql mysql-client mysql-community-server
然後我們需要創建MySQL系統的啓動鍵鏈接啓動MySQL服務器，這樣以便於MySQL在系統啓動時自動啓動，
systemctl enable mysql.service
systemctl start mysql.service
爲了確保MySQL的安裝完成，運行：
mysql_secure_installation
下面會遇到下面的提示問題；
server1：~ # 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)： <-- 輸入密碼
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] <-- 輸入Y
New password： <-- 設置數據庫密碼
Re-enter new password： <-- 重新輸入數據庫密碼
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] <-- 選擇Y
... Success！
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] <-- 選擇Y
... Success！
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] <-- 選擇Y
- Dropping test database...
... Success！
- Removing privileges on test database...
... Success！
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now？ [Y/n] <-- 選擇Y
... Success！
Cleaning up...
All done！ If you've completed all of the above steps， your MySQL
installation should now be secure.
Thanks for using MySQL！
