Centos6.5安装MySQL5.6

1. 查看系统状态

[root@itzhouq32 tools]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

[root@itzhouq32 tools]# uname -a
Linux itzhouq32 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

2.创建需要下载rpm软件包的目录

[root@itzhouq32 /]# mkdir soft
[root@itzhouq32 /]# cd soft
[root@itzhouq32 soft]# ls
[root@itzhouq32 soft]#

3. 查看系统中是否有已经存在的MySQL

如果有需要卸载
用这个查找
# rpm -qa | grep mysql
用这个卸载

yum -y remove mysql-libs-5.1*

4. 下载MySQL-5.6安装包

分别执行下面的三条命令

# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm
# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm

如果下载的速度太慢，也可以使用window下载后传输到虚拟机的这个目录，然后安装。

5. 安装

# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm

如果有以下报错信息，需要安装依赖包。

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

执行：

# yum install -y libaio

再次安装

# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm

# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm 
Preparing...                ########################################### [100%]
   1:MySQL-client           ########################################### [100%]

6. 修改配置文件位置

# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

7. 初始化MySQL

# /usr/bin/mysql_install_db
# /etc/init.d/mysql start
# ps -ef | grep mysql
# netstat -anpt | grep 3306
# more /root/.mysql_secret

然后会显示你的数据库随机码

# The random password set for the root user at Fri Mar 15 01:43:14 2019 (local time): BKEIavP3r8C8wNoB

8. 登录

# mysql -uroot -pBKEIavP3r8C8wNoB

登录成功后会显示版本信息

mysql>

9. 设置新密码

mysql> SET PASSWORD = PASSWORD('2626');
Query OK, 0 rows affected (0.00 sec)

mysql> EXIT
Bye

我设置了密码为2626，并退出MySQL

10. 设置MySQL服务开机自启动

# chkconfig mysql on
# chkconfig mysql --list
mysql           0:关闭    1:关闭    2:启用    3:启用    4:启用    5:启用    6:关闭

11. 检查服务状态

# service mysql status
 SUCCESS! MySQL running (2447)

OK，打完收工了！
