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

Warning: Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

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)

12. 开启MySQL的远程登录

默认情况下MySQL为安全起见，不支持远程登录MySQL，所以需要设置开启登录MySQL的权限。登录MySQL后输入命令：

mysql> grant all privileges on *.* to 'root' @'%' identified by '2626'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)

其中2626是用于远程访问的密码，可以与root密码不一样。这样别的用户远程访问你的数据库时，可以使用root账号，密码2626登录。

13. 开放Linux的对外访问的端口

[root@itzhouq32 bin]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT [root@itzhouq32 bin]# /etc/rc.d/init.d/iptables save iptables：将防火墙规则保存到 /etc/sysconfig/iptables： [确定] [root@itzhouq32 bin]#

OK，打完收工了！
