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@localhost]# 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@localhost]# 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@localhost]# rpm -e mysql-5.0.45-7.el5.i386 --nodeps
[root@localhost]# rpm -e mysql-server-5.0.45-7.el5.i386 –nodeps
[root@localhost]# rpm -ivh MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

3、 启动mysql并设置登录密码
[root@localhost]# /etc/init.d/mysql start
StartingMySQL......[ OK ]
[root@localhost]# mysqladmin -u rootpassword "123456"
4、 登录mysql并创建数据库
[root@localhost]# mysql -u root -p
Enterpassword:

5、 配置客户端连接
mysql>use mysql;
Readingtable information for completion of table and column names
Youcan turn off this feature to get a quicker startup with -A

mysql>grant all on *.* to root@"%" identified by "123456";
QueryOK, 0 rows affected (0.00 sec)
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@localhost]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
[root@localhost]# 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:
#http://dev.mysql.com/doc/mysql/en/option-files.html
#
# 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
skip-external-locking
key_buffer_size= 16M
max_allowed_packet= 1M

net_buffer_length= 8K
read_buffer_size= 256K

skip-name-resolve
#Don't listen on a TCP/IP port at all. This can be a security enhancement,
# ifall processes that need to connect to mysqld run on the same host.
# Allinteraction with mysqld must be made via Unix sockets or named pipes.
