centos6.5安裝mysql

開始安裝MySQL5

　　首先咱們應該先用下面的命令安裝MySQL：

　　yum install mysql mysql-server

　　而後咱們須要建立MySQL系統的啓動鍵連接啓動MySQL服務器，這樣以便於MySQL在系統啓動時自動啓動

    chkconfig --levels 235 mysqld on
    /etc/init.d/mysqld start

　　爲MySQL root賬戶設置密碼：

    mysql_secure_installation

    會出現下面的一系列提示：

　　root@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)：

　　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] <-- ENTER

　　New password： <-- yourrootsqlpassword

　　Re-enter new password： <-- yourrootsqlpassword

　　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] <-- ENTER

　　... 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] <-- ENTER

　　... 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] <-- ENTER

　　- 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] <-- ENTER

　　... 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！
