CentosMySQL5.6安装方法

1. download rpm包
先确定系统版本
[root@xcldtc5m /]# cat /proc/version
Linux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 03:15:09 UTC 2013
下载mysql rpm包
wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-server-5.6.22-1.el6.x86_64.rpm
wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-devel-5.6.22-1.el6.x86_64.rpm
wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.6/MySQL-client-5.6.22-1.el6.x86_64.rpm
2. 安装
[root@xcldtc5m mysql]# rpm -ivh MySQL-server-5.6.22-1.el6.x86_64.rpm
[root@xcldtc5m mysql]# rpm -ivh MySQL-devel-5.6.22-1.el6.x86_64.rpm
[root@xcldtc5m mysql]# rpm -ivh MySQL-client-5.6.22-1.el6.x86_64.rpm
发现缺libaio.so包
error: Failed dependencies:
/usr/bin/perl is needed by MySQL-server-5.6.22-1.el6.x86_64
libaio.so.1()(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.22-1.el6.x86_64
error: Failed dependencies:
/usr/bin/perl is needed by MySQL-server-5.6.22-1.el6.x86_64
解决方法
[root@xcldtc5m mysql]# yum install libaio
[root@xcldtc5m mysql]# yum install perl
若处理mysql版本冲突，先移除已经安装的mysql
[root@xcldtc5m mysql]# yum -y remove mysql-libs-5.1.71*
3.修改配置文件位置
root@xcldtc5m mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
4，初使化MYSQL及配置密码
[root@xcldtc5m mysql]# /usr/bin/mysql_install_db
[root@xcldtc5m mysql]# service mysql start
[root@xcldtc5m mysql]# cat /root/.mysql_secret
# The random password set for the root user at Sat Feb 7 10:54:24 2015 (local time): VoKvw3vpo_3LiA3c
[root@xcldtc5m mysql]# mysql -uroot -pVoKvw3vpo_3LiA3c
mysql> SET PASSWORD = PASSWORD('2345678');
mysql> exit
[root@xcldtc5m mysql]# mysql -uroot -p2345678
5.远程登录配置
mysql> use mysql
mysql> select host ,user ,password from user;
+-----------+------+-------------------------------------------+
| host | user | password |
+-----------+------+-------------------------------------------+
| localhost | root | *BC1C4715C23459AB982AD2D6617B4F8790161763 |
| xcldtc5m | root | *44CF61DA6CDeeee2085F4598F728CF221DA8F167 |
| 127.0.0.1 | root | *44CF61DA6CD83e32085F4598F728CF221DA8F167 |
| ::1 | root | *44CF61DA6CD86832345F4598F728CF221DA8F167 |
+-----------+------+-------------------------------------------+
mysql> update user set password=password('234567') where user='root';
mysql> update user set host='%' where host='localhost';

6，设置开机自启动
[root@xcldtc5m mysql]# chkconfig mysql on
[root@xcldtc5m mysql]# chkconfig --list | grep mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
7，查看mysql配置文件位
[root@xcldtc5m mysql]# mysqld --verbose --help | grep -A 1 'Default options'
8，MYSQL默认安装位置

/var/lib/mysql/ #数据库目录 /usr/share/mysql #配置文件目录

/usr/bin #相关命令目录 /etc/init.d/mysql #启动脚本
