rpm方式安装mysql5.6
a. 检查mysql及相关rpm包，是否安装，如果有安装，则移除（rpm –e 名称）
1 [root@localhost ~]# rpm -qa | grep -i mysql
2 mysql-libs-5.1.66-2.el6_3.x86_64
3 [root@localhost ~]# yum -y remove mysql-libs*
b. 下载linux对应的rpm包，如：centos6.4_64对应的rpm包，如下：
1 [root@localhost rpm]# ll
2 total 74364
3 -rw-r--r--. 1 root root 18442536 dec 11 20:19 mysql-client-5.6.15-1.el6.x86_64.rpm
4 -rw-r--r--. 1 root root  3340660 dec 11 20:06 mysql-devel-5.6.15-1.el6.x86_64.rpm
5 -rw-r--r--. 1 root root 54360600 dec 11 20:03 mysql-server-5.6.15-1.el6.x86_64.rpm
c. 安装mysql
1 [root@localhost rpm]# rpm -ivh mysql-server-5.6.15-1.el6.x86_64.rpm
2 [root@localhost rpm]# rpm -ivh mysql-devel-5.6.15-1.el6.x86_64.rpm
3 [root@localhost rpm]# rpm -ivh mysql-client-5.6.15-1.el6.x86_64.rpm
4 #修改配置文件位置
5 [root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
d. 初始化mysql及设置密码
1 [root@localhost rpm]# /usr/bin/mysql_install_db
2 [root@localhost rpm]# service mysql start
3 [root@localhost rpm]# cat /root/.mysql_secret  #查看root账号密码
4 # the random password set for the root user at wed dec 11 23:32:50 2013 (local time): qktafznl
5 [root@localhost ~]# mysql -uroot –pqktafznl
6 mysql> set password = password('123456');    #设置密码为123456
7 mysql> exit
8 [root@localhost ~]# mysql -uroot -p123456
e. 允许远程登陆
01 mysql> use mysql;
02 mysql> select host,user,password from user;
03 +-----------------------+------+-------------------------------------------+
04 | host                  | user | password                                  |
05 +-----------------------+------+-------------------------------------------+
06 | localhost             | root | *6bb4837eb74329105ee4568dda7dc67ed2ca2ad9 |
07 | localhost.localdomain | root | *1237e2ce819c427b0d8174456dd83c47480d37e8 |
08 | 127.0.0.1             | root | *1237e2ce819c427b0d8174456dd83c47480d37e8 |
09 | ::1                   | root | *1237e2ce819c427b0d8174456dd83c47480d37e8 |
10 +-----------------------+------+-------------------------------------------+
11
12 mysql> update user set password=password('123456') where user='root';
13 mysql> update user set host='%' where user='root' and host='localhost';
14 mysql> flush privileges;
15 mysql> exit
f. 设置开机自启动
1 [root@localhost ~]# chkconfig mysql on
2 [root@localhost ~]# chkconfig --list | grep mysql
3 mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off
g. mysql的默认安装位置
1 /var/lib/mysql/               #数据库目录
2 /usr/share/mysql              #配置文件目录
3 /usr/bin                     #相关命令目录
4 /etc/init.d/mysql              #启动脚本
修改字符集和数据存储路径
配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8.
