大家好， 本教程将在CentOS/RHEL系统上安装MySQL 5.6数据库。我使用CentOS 6的32位版本。对于其他操作系统版本你可以从下载文件
在这里 。同时更改所有命令给出的rpm名称在本教程中。
第1步：从MySQL下载RPM包
从MySQL CDN网络使用下面的下载链接，下载需要的rpm文件。
# cd /opt/
# wget http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.15-1.el6.i686.rpm
# wget http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.15-1.el6.i686.rpm
# wget http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-shared-5.6.15-1.el6.i686.rpm
第2步：安装MySQL的RPM
安装使用rpm命令行工具下载的rpm。
# rpm -ivh MySQL-server-5.6.15-1.el6.i686.rpm
# rpm -ivh MySQL-client-5.6.15-1.el6.i686.rpm
# rpm -ivh MySQL-shared-5.6.15-1.el6.i686.rpm
第3步：启动MySQL服务
安装RPM包使用下面的命令来启动mysql服务后。
# /etc/init.d/mysql start
Starting MySQL.. SUCCESS!
第4步：初始MySQL配置
执行
mysql_secure_installation脚本并按照向导。它会提示输入根口令。要获取临时root密码检查'/root/.mysql_secret'文件
# /usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Cleaning up...
第5步：登录到MySQL
现在，你已经成功地安装了MySQL 5.6。让使用root访问权限登录到MySQL并尝试创建一个数据库。 root用户密码可以发现 /root/.mysql_secret 。
# mysql -u root -p
创建使用下面的命令一个虚拟数据库。
mysql> create database dummydb;
Query OK, 1 row affected (0.01 sec)
第6步：检查版本的MySQL
验证您的系统上安装的MySQL版本。下面的命令会显示已安装的MySQL版本。
# mysql -V
mysql Ver 14.14 Distrib 5.6.15, for Linux (i686) using EditLine wrapper
