1、安裝依賴(lài)

[root@node001 ~]# yum install -y perl

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

base | 3.7 kB 00:00

extras | 3.4 kB 00:00

updates | 3.4 kB 00:00

Setting up Install Process

Package 4:perl-5.10.1-144.el6.x86_64 already installed and latest version

Nothing to do

2、?卸載舊版本的mysql及插件

[root@node001 ~]# rpm -qa | grep mysql

mysql-5.1.73-8.el6_8.x86_64

mysql-libs-5.1.73-8.el6_8.x86_64

mysql-server-5.1.73-8.el6_8.x86_64

[root@node001 ~]#rpm -e mysql-5.1.73-8.el6_8.x86_64 --nodeps

[root@node001 ~]# rpm -e mysql-libs-5.1.73-8.el6_8.x86_64?--nodeps

[root@node001 ~]# rpm -e mysql-server-5.1.73-8.el6_8.x86_64?--nodeps

(--nodeps:忽略其他依賴(lài)，直接卸載)

3、 安裝rpm(4個(gè))

安裝包

[root@node001 ~]#tar zxvf mysql.tar.gz

MySQL-client-5.6.28-1.el6.x86_64.rpm

MySQL-devel-5.6.28-1.el6.x86_64.rpm

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

4、上傳mysql配置文件my.cnf

[root@node001 ~]# cd /etc

上傳文件

[root@node001 etc]# ls /etc/my.cnf

/etc/my.cnf

5、初始化

--defaults-file argument to mysqld_safe when starting the server

6、 ?啟動(dòng)mysql

[root@node001 etc]# service mysql start

Starting MySQL....... SUCCESS!

7、重置密碼

查看初始化密碼

[root@node001 etc]# cat /root/.mysql_secret
