准备环境：

RedHat 5系统、MySQL 5.6 rpm包

首先 上传mysql至服务器

1、 解压缩MySql

[root@]# tar -xvf MySQL-5.6.2_m5-1.rhel5.i386.tar

MySQL-client-5.6.2_m5-1.rhel5.i386.rpm

MySQL-devel-5.6.2_m5-1.rhel5.i386.rpm

MySQL-embedded-5.6.2_m5-1.rhel5.i386.rpm

MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

MySQL-shared-5.6.2_m5-1.rhel5.i386.rpm

MySQL-test-5.6.2_m5-1.rhel5.i386.rpm

2、 安装MySQL-server包

[root@]# rpm -ivh MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

error:Failed dependencies:

     MySQL conflicts with mysql-5.0.45-7.el5.i386

         MySQL-serverconflicts with mysql-server-5.0.45-7.el5.i386

（安装失败，，由于系统先前安装有mysql,把它卸载掉！再安装）

        [root@]# rpm -e mysql-5.0.45-7.el5.i386 --nodeps

[root@]# rpm -e mysql-server-5.0.45-7.el5.i386 –nodeps

[root@]# rpm -ivh MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

3、 启动mysql并设置登录密码

[root@]# /etc/init.d/mysql start

StartingMySQL......[  OK  ]

[root@shiyue5 u01]# mysqladmin -u rootpassword "123456"

4、 登录mysql并创建数据库

[root@shiyue5~]# mysql -u root -p

Enterpassword:

5、 配置客户端连接

通过对1042问题代码的查询，得出编辑/etc/my.cnf文件，在[mysqld]内添加一行skip-name-resolve

在/etc/目录下如没有my.cnf配置文件，则请到/usr/share/mysql/下找到*.cnf文件，拷贝其中的一个到/etc/并改名为my.cnf

[root@shiyue5~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

[root@shiyue5~]# vi /etc/my.cnf

 

#Example MySQL config file for medium systems.

#

# Thisis for a system with little memory (32M - 64M) where MySQL plays

# animportant part, or systems up to 128M where MySQL is used together with

#other programs (such as a web server)

#

#MySQL programs look for option files in a set of

#locations which depend on the deployment platform.

# Youcan copy this option file to one of those

#locations. For information about these locations, see:

#

#

# Inthis file, you can use all long options that a program supports.

# Ifyou want to know which options a program supports, run the program

# withthe "--help" option.

 

# Thefollowing options will be passed to all MySQL clients

[client]

#password       = your_password

port            = 3306

socket          = /var/lib/mysql/mysql.sock

 

# Herefollows entries for some specific programs

 

# TheMySQL server

[mysqld]

port            = 3306

socket          = /var/lib/mysql/mysql.sock
