CentOS6.5系统下RPM包安装MySQL5.6

From:http://www.linuxidc.com/Linux/2015-04/116003.htm

1.查看操作系统相关信息。

[root@linuxidc ~]# cat /etc/issue 
CentOS release 6.5 (Final) 
Kernel \r on an \m 
[root@linuxidc ~]# uname -a 
Linux linuxidc 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

x86_64是64位，如果还不确定，可以再换个命令

#getconf LONG_BIT
64　

2.创建需要下载rpm软件包的目录。
1 [root@linuxidc ~]# mkdir -p /taokey/tools

3.查看下是否有系统自带mysql的rpm包，如果有，需要删除自带的旧rpm包。

[root@linuxidc ~]# rpm -qa | grep mysql 
mysql-libs-5.1.71-1.el6.x86_64 
[root@linuxidc ~]# yum -y remove mysql-libs-5.1* 
[root@linuxidc ~]# rpm -qa | grep mysql 
[root@linuxidc ~]#

　　

4.在MySQL官网下载安装MySQL-5.6.21所需的rpm软件包。
需要下载三个rpm软件包：
MySQL-client-5.6.21-1.rhel5.x86_64.rpm  
MySQL-devel-5.6.21-1.rhel5.x86_64.rpm  
MySQL-server-5.6.21-1.rhel5.x86_64.rpm 

[root@linuxidc ~]# cd /taokey/tools/ 
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm 
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm 
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm

5.下载完之后，安装三个rpm软件包。

[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm 
error: Failed dependencies:
        libaio.so.1()(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
        libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
        libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64

　　

安装MySQL-server报错，原因是没有安装libaio，系统缺少libaio.so此软件包，下边yum安装一下libaio.so软件包。

[root@linuxidc tools]# yum install -y libaio 
[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm 
[root@linuxidc tools]# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm

mysql数据库默认的一些主要目录：

(1)、数据库目录　/var/lib/mysql/

(2)、配置文件　　/usr/share/mysql（mysql.server命令及配置文件）

(3)、相关命令　　/usr/bin (mysqladmin mysqldump等命令)

(4)、启动脚本　　/etc/rc.d/init.d/（启动脚本文件mysql的目录）

6.修改配置文件位置。

[root@linuxidc tools]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

　　

7.初始化MySQL及修改MySQL默认的root密码。

[root@linuxidc tools]# /usr/bin/mysql_install_db 
[root@linuxidc tools]# ps -ef | grep mysql 
root      2188    1  0 14:48 pts/1    00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/linuxidc.pid 
mysql    2303  2188 30 14:48 pts/1    00:00:02 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/linuxidc.err --pid-file=/var/lib/mysql/linuxidc.pid 
root      2331  1853  0 14:49 pts/1    00:00:00 grep mysql 
[root@linuxidc tools]# netstat -anpt | grep 3306

[root@linuxidc tools]# more /root/.mysql_secret 
# The random password set for the root user at Thu Apr  9 14:43:59 2015 (local time): F6K3v_xggFoLQeiN 
  
[root@linuxidc tools]# mysql -uroot -pF6K3v_xggFoLQeiN

按照上面的步骤，本人在 连接mysql  （# mysql -uroot -pF6K3v_xggFoLQeiN ）时 报错Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' ，原因是mysql 还未启动，最后还是通过下面的语句启动了mysql，再输入用户名密码连接，成功。

[root@iZ25oux6yl1Z etc]# /etc/init.d/mysql start

　　

9.增设加用户名密码：

grant all privileges on *.* to username@'localhost' identified by 'password' with grant option;
grant all privileges on *.* to username@'%' identified by 'password' with grant option;

第一句增加username用户授权通过本地机（localhost)访问，密码“password”。第二句则是授与username用户从任何其它主机发起的访问（通配符％）。　　

　　

10.设置MySQL服务开机自启动。

[root@linuxidc tools]# chkconfig mysql on 
[root@linuxidc tools]# chkconfig mysql --list 
mysql          0:off  1:off  2:on    3:on    4:on    5:on    6:off

　　

到此为止，使用RPM安装MySQL5.6版本数据库安装完毕，谢谢大家。
