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

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)
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!
