MySQL5.5.25（rpm）安装及升级到5.6.26 for RedHat Enterprise Linux 6.4
环境：RedHat Enterprise Linux 6.4（64bit) MySQL:5.6.25 IP：192.168.15.166
步骤一：准备工作：
a、建议删除系统存在的mysql用户 [root@mysql01 Desktop]# idmysql
uid=27(mysql) gid=27(mysql) groups=27(mysql) [root@mysql01 Desktop]# userdel -r mysql
b、清理已安装的mysql程序包 [root@suzzy ~]# rpm -qa|grepmysql mysql-server-5.1.66-2.el6_3.x86_64 dovecot-mysql-2.0.9-5.el6.x86_64 qt-mysql-4.6.2-25.el6.x86_64 rsyslog-mysql-5.8.10-6.el6.x86_64 mysql-5.1.66-2.el6_3.x86_64
mod_auth_mysql-3.0.0-11.el6_0.1.x86_64 mysql-devel-5.1.66-2.el6_3.x86_64 mysql-libs-5.1.66-2.el6_3.x86_64
使用rpm -e 包名（都地上面显示）来清除安装包，如果碰到不能报错不能删除，加上参数 --nodeps强制删除即可。 例如：
[root@suzzy ~]# rpm -e qt-mysql-4.6.2-25.el6.x86_64 error: Failed dependencies:
qt4-mysql is needed by (installed) akonadi-1.2.1-2.el6.x86_64 [root@suzzy ~]# rpm -e qt-mysql-4.6.2-25.el6.x86_64 --nodeps
[root@suzzy ~]#rpm -e mysql-server-5.1.66-2.el6_3.x86_64 --nodeps [root@suzzy ~]# rpm -e dovecot-mysql-2.0.9-5.el6.x86_64 --nodeps [root@suzzy ~]# rpm -e qt-mysql-4.6.2-25.el6.x86_64 --nodeps [root@suzzy ~]# rpm -e rsyslog-mysql-5.8.10-6.el6.x86_64 --nodeps [root@suzzy ~]# rpm -e mysql-5.1.66-2.el6_3.x86_64 --nodeps
[root@suzzy ~]# rpm -e mod_auth_mysql-3.0.0-11.el6_0.1.x86_64 --nodeps [root@suzzy ~]# rpm -e mysql-devel-5.1.66-2.el6_3.x86_64 --nodeps [root@suzzy ~]# rpm -e mysql-libs-5.1.66-2.el6_3.x86_64 --nodeps
直到下面语句找不到mysql包为止
[root@mysql01 ~]# rpm -qa | grepmysql [root@mysql01 ~]#
注意：在卸载完成之后需要删除配置文件/etc/my.cnf和数据库文件/var/lib/mysql，保守起见
可将配置文件my.cnf进行改名处理。
[root@mysql01 Desktop]# rpm -qpl MySQL-client-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-devel-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-embedded-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-server-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-shared-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-shared-compat-advanced-5.6.25-1.el6.x86_64.rpm [root@mysql01 Desktop]# rpm -qpl MySQL-test-advanced-5.6.25-1.el6.x86_64.rpm
步骤二：开始安装
1、建立用户组及用户
[root@mysql01 ~]# groupaddmysql
[root@mysql01 ~]# useradd -g mysqlmysql
2、将下载好的mysql程序rpm包上传至服务器 此处略过 或者：
[root@mysql01 Desktop]# unzip V76360-01.zip [root@mysql01 Desktop]# rpm -ivh MySQL-*

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.

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
[root@mysql01 Desktop]# cat /root/.mysql_secret
# The random password set for the root user at Fri Aug 28 10:57:02 2015 (local time): FY2X3PPff8VzaEn5
3、配置并启动mysql及设置开机自动启动
[root@mysql01 Desktop]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf [root@mysql01 Desktop]# ls -l /etc/my.cnf
-rwxr-xr-x. 1 root root 1126 Aug 28 11:09 /etc/my.cnf [root@mysql01 Desktop]# ps -ef | grepmysql
root 5369 5167 0 11:10 pts/1 00:00:00 grepmysql [root@mysql01 Desktop]# servicemysql start Starting MySQL..[ OK ]
[root@mysql01 Desktop]# servicemysql status
MySQL running (5507) [ OK ]
[root@mysql01 Desktop]# chkconfig --list | grepmysql mysql
备注：如2、3、4为off，即mysql位设置为开机自动启动，可以使用如下方法设置 [root@mysql01 Desktop]# chkconfig --list | grepmysql mysql
0:off
1:off
2:off
3:off
4:off
5:off
6:off
[root@mysql01 Desktop]# chkconfig --level 2345 mysql on [root@mysql01 Desktop]# chkconfig --list | grepmysql mysql
4、登录系统：
[root@mysql01 Desktop]# mysql -uroot -p Enter password: FY2X3PPff8VzaEn5 或者：
[root@mysql01 Desktop]# mysql -u root -p Enter password: FY2X3PPff8VzaEn5 或者：
[root@mysql01 Desktop]# mysql -uroot -pFY2X3PPff8VzaEn5 或者：
[root@mysql01 Desktop]# mysql -u root -pFY2X3PPff8VzaEn5 或者：
[root@mysql01 Desktop]# mysql -uroot -pFY2X3PPff8VzaEn5
Welcome to the MySQL monitor. Commands end with ; or \\g.
