#### 0 oracle官网上下载的mysql有以下几个rpm包 ####

#### 1 查询服务器上已经安装的mysql ####

rpm -aq | grep mysql    
    
        mysql-5.0.77-3.el5
        mysql-server-5.0.77-3.el5
        libdbi-dbd-mysql-0.8.1a-1.2.2
        mysql-connector-odbc-3.51.26r1127-1.el5
        mysql-5.0.77-3.el5
    
        ---
        qt-mysql-4.6.2-25.el6.x86_64
    
        mysql-connector-odbc-5.1.5r1144-7.el6.x86_64
        mysql-bench-5.1.66-2.el6_3.x86_64
        mysql-devel-5.1.66-2.el6_3.x86_64
        libdbi-dbd-mysql-0.8.3-5.1.el6.x86_64
        mysql-test-5.1.66-2.el6_3.x86_64
        mysql-libs-5.1.66-2.el6_3.x86_64
        mysql-5.1.66-2.el6_3.x86_64
        mysql-connector-java-5.1.17-6.el6.noarch
        mysql-server-5.1.66-2.el6_3.x86_64

#### 2 卸载旧的版本 ####

rpm -e mysql --nodeps --allmatches (不理会依赖关系，删除所有上一步查出来的相同的mysql)
    
        [root@localhost home]#  rpm -e mysql-connector-odbc-3.51.26r1127-1.el5 --nodeps --allmatches
        [root@localhost home]#  rpm -e libdbi-dbd-mysql-0.8.1a-1.2.2 --nodeps --allmatches
        [root@localhost home]#  rpm -e mysql-server-5.0.77-3.el5 --nodeps --allmatches
    
        [root@localhost home]# rpm -aq | grep mysql
        [root@localhost home]#

#### 3 将老版本的几个文件手工删除 ####

#rm -f /etc/my.cnf
        #rm -rf /var/lib/mysql
        #rm -rf/var/share/mysql
        # rm -rf/usr/bin/mysql*

#### 4 上传mysql的安装包 ####

MySQL-client-advanced-5.6.20-1.el6.x86_64.rpm
        MySQL-devel-advanced-5.6.20-1.el6.x86_64.rpm
        MySQL-server-advanced-5.6.20-1.el6.x86_64.rpm

#### 5 安装服务器和客户端 ####

#rpm -ivh MySQL-server-advanced-5.6.****-1.el6.x86_64.rpm
    
            A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
            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.mysql.com/
    
            The latest information about MySQL is available on the web at
    
              http://www.mysql.com
    
            Support MySQL by buying support/licenses at http://shop.mysql.com
    
            New default config file was created as /usr/my.cnf and
            will be used by default by the server when you start it.
            You may edit this file to change server settings
    
        #rpm -ivh MySQL-client-advanced-5.6.****-1.el6.x86_64.rpm
        说明:不安装mysql-client是不能使用mysql工具登陆到mysql数据库

#### 6 oracle收购Mysql后,新版的mysql刚安装完mysql后不能直接输入mysql登录数据库, ####

而是设置了默认free password密码,默认密码放在了/root/.mysql_secret文件中,登陆后需要修改密码

#### 7 修改密码 ####

(1)查看文件寻找密码
        vi /root/.mysql_secret
    (2)登陆Mysql
            linux mysql 服务启动和关闭 
                service mysql start         service mysql stop
    
        登陆服务器
            mysql -u root -p
    (3)修改密码
            mysql> set password=password('123456') ; 
    
            也可以使用脚本 /usr/bin/mysql_secure_installation进行交互式的修改mysql的root密码
