centos6.5安裝mysql5.6，centos6.5mysql5.6
1. 先查看版本號碼

# uname -a

2. 下載並安裝Mysql的yum倉庫

下載Mysql的yum倉庫

http://dev.mysql.com/downloads/repo/yum/

然後安裝一下這個倉庫列表

$ sudo yum localinstall mysql-community-release-el6-5.noarch.rpm 

3. 搜尋可安裝的mysql版本

執行這個命令後就能看到可安裝的mysql：

# yum repolist enabled | grep "mysql.*-community.*"

如果我們是要安裝最新的版本，那麼可以直接執行

# sudo yum install mysql-community-server

如果我們要選擇版本，可以先執行下面這個命令查看一下有哪些版本：

# yum repolist all | grep mysql

如果要選擇版本的話，有兩種方式，一種是使用命令來

$ sudo yum-config-manager --disable mysql56-community$ sudo yum-config-manager --enable mysql57-community-dmr

這個命令就是在倉庫中啟用5.7版本的，禁用5.6版本子倉庫
或者編輯/etc/yum.repos.d/mysql-community.repo檔案

# Enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=//repo.mysql.com/yum/mysql-5.6-community/el/5/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql 

enabled=0表示禁用
比如要安裝5.7版本的mysql，要確定5.6的enabled=0，5.7的enabled=1，一次保證只啟用一個子倉庫

# Note: MySQL 5.7 is currently in development. For use at your own risk.# Please read with sub pages: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/[mysql57-community-dmr]name=MySQL 5.7 Community Server Development Milestone Releasebaseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

然後我們又可以愉快的安裝mysql了

$ sudo yum install mysql-community-server

安裝完成後我們啟動mysql

$ sudo service mysqld start

查看mysql狀態

$ sudo service mysqld status

啟動mysql服務並初始化：

# /etc/init.d/mysqld startInitializing MySQL database: PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !To do so, start the server, then issue the following commands:/usr/bin/mysqladmin -u root password 'new-password'/usr/bin/mysqladmin -u root -h iZ94vana2fdZ password 'new-password'Alternatively you can run:/usr/bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default.
