一、卸载自带mysql，删除MySQL的lib库，服务文件
[root@localhost ~]#rpm -qa|grep mysql
qt-mysql-4.6.2-26.el6_4.x86_64
mysql-5.1.71-1.el6.x86_64
mysql-libs-5.1.71-1.el6.x86_64
mysql-devel-5.1.71-1.el6.x86_64
mysql-server-5.1.71-1.el6.x86_64
[root@localhost ~]# rpm -e --nodeps qt-mysql-4.6.2-26.el6_4.x86_64
[root@localhost ~]# rpm -e --nodeps mysql-5.1.71-1.el6.x86_64
[root@localhost ~]# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64
[root@localhost ~]# rpm -e --nodeps mysql-devel-5.1.71-1.el6.x86_64
[root@localhost ~]# rpm -e --nodeps mysql-server-5.1.71-1.el6.x86_64
[root@localhost ~]# rpm -qa|grep mysql
[root@localhost ~]#
清除所有mysql相关文件：
[root@localhost ~]#find / -name mysql
/usr/lib64/perl5/DBD/mysql
/usr/lib64/perl5/auto/DBD/mysql
/usr/share/mysql
[root@localhost ~]#rm –rf /usr/lib64/perl5/DBD/mysql
[root@localhost ~]#rm –rf /usr/lib64/perl5/auto/DBD/mysql
[root@localhost ~]#rm –rf /usr/share/mysql
查看是否有残留文件：
[root@localhost ~]#rpm -qa | grep mysql
二、安装MySQL
1.复制mysql安装包到安装目录
准备源码包：MySQL-5.6.36-1.linux_glibc2.5.i386.rpm-bundle.tar
将源码包以二进制方式上传到/usr/appsoft/software目录下
2.解压安装包
[root@localhost ~]cd /usr/appsoft/software
[root@localhost software]# tar xvf MySQL-5.6.36-1.linux_glibc2.5.i386.rpm-bundle.tar
将解压出以下文件：
MySQL的测试组件MySQL-shared-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL的共享库MySQL-shared-compat-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL版本兼容的包MySQL-client-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL客户端程序MySQL-devel-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL的库和头文件MySQL-embedded-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL的嵌入式程序MySQL-server-5.6.22-1.linux_glibc2.5.i386.rpm
MySQL服务端程序
3.安装服务端
[root@localhost software]# rpm -ivh rpm -ivh MySQL-server-5.6.36-1.rhel5.i386.rpm
warning: MySQL-server-5.6.36-1.rhel5.i386.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:

[root@ localhost software]# find / -name libaio.so.1
/lib64/libaio.so.1
[root@ localhost software]# find / -name libstdc++.so.6
/usr/lib64/libstdc++.so.6
如果出现以上错误说明缺少libaio.so.1和libstdc++.so.6
将libaio-0.3.107-10.el6.i686.rpm和libstdc++-4.4.7-4.el6.i686.rpm上传到/usr/appsoft/software并安装。
安装libaio-0.3.107-10.el6.i686.rpm：
[root@ localhost software]# rpm -ivh libaio-0.3.107-10.el6.i686.rpm
warning: libaio-0.3.107-10.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

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
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
4.安装库文件
[root@ localhost software]# rpm -ivh MySQL-devel-5.6.36-1.rhel5.i386.rpm

MySQL默认安装路径：
a.数据库目录： /var/lib/mysql/
b.配置文件： /usr/share/mysql
c.相关命令： /usr/bin
d.启动脚本： /etc/rc.d/init.d/
6.修改配置文件，将MySQL的配置文件拷贝到/etc目录下。
[root@localhost mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
修改/etc/my.cnf，让数据库不区分表名大小写（此处错误会导致‘创建其他表’时错误）
在[mysqld]配置项下加入以下语句
lower_case_table_names=1
赋予用户写二进制备份数据的权限（创建触发器时必须有这权限）
log_bin_trust_function_creators=1
默认断开连接时间设为1年
wait_timeout=31536000
interactive_timeout=31536000
解决连接数据库过慢问题：
在[mysqld]下加入以下内容
character-set-server = utf8
character-set-filesystem = utf8
skip-name-resolve
不需要存日志的时候注释掉log-bin=mysql-bin
如果你需要日志，最好控制一下这些日志文件保留的天数，可以通过下面的配置设定日志文件保留的天数：
expire_logs_days = 7
表示保留7天的日志，这样老日志会自动被清理掉。
7.初始化MySQL
[root@localhost mysql]# /usr/bin/mysql_install_db
8.启动MySQL
[root@localhost mysql]# service mysql start
Starting MySQL.... SUCCESS!
检测mysql 3306是否安打开
[root@localhost mysql]# netstat -nattcp |grep 3306
0 0 :::3306 :::* LISTEN
9.从.mysql_secret查看root账号初始密码
[root@localhost mysql]# cat /root/.mysql_secret
The random password set for the root user at Thu Dec 18 21:08:44 2014 (local time): vuN8xfuKTRnmqX3I
其中vuN8xfuKTRnmqX3I为root账号的初始密码。
10.使用默认密码登陆mysql
[root@localhost mysql]# mysql -u root -pvuN8xfuKTRnmqX3I
Warning: Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.

修改默认密码：

Bye
11.添加自启动服务
[root@localhost ~]# chkconfig --add mysql
[root@localhost ~]# chkconfig mysql on
12.创建数据库
mysql –u root –p iesapp
create database ms DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;
create database ls DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;
设置访问权限（所有机器都可访问）
GRANT ALL PRIVILEGES ON 数据库名 TO '用户名'@'%' IDENTIFIED BY '密码';
flush privileges ;
quit;
重启mysql服务即可使用
service mysql restart;
关闭防火墙
[root@localhost ~]# service iptables stop
iptables: Flushing firewall rules:
[ OK ]iptables: Setting chains to policy ACCEPT: filter
[ OK ]iptables: Unloading modules:
[ OK ]
[root@localhost ~]# service iptables status
iptables: Firewall is not running.
