[百晓生]-Fedora17 Mysql 安装及配置

1.安装 Mysql Server

# yum install mysql mysql-server

可以到mysql官网去下载，我下载的是通用版本。你需要下载下面四个文件就可以了。

mysql-client --------客户端包

mysql-server --------主服务器包

mysql-devel ---------开发包，作为开发者，这个是必须的，其提供开发用的头文件和库文件

mysql-shared ----共享组建包-----外部客户端使用的共享库

然后安装就可以了

2.开启 MySQL server 及开机启动 MySQL

# systemctl start mysqld.service

# systemctl enable mysqld.service

ln -s '/usr/lib/systemd/system/mysqld.service' '/etc/systemd/system/multi-user.target.wants/mysqld.service'

或者使用：# sudo chkconfig --levels 235 mysqld on

注意：正在将请求转发到“systemctl enable mysqld.service”。

3.MySQL Secure Installation

# /usr/bin/mysql_secure_installation

通过操作将进行以下各项过程

Set (Change) root password

Remove anonymous users

Disallow root login remotely

Remove test database and access to it

Reload privilege tables output:

$ sudo /usr/bin/mysql_secure_installation

[sudo] password for tiny:

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 currentpassword for the root user. If you've just installed MySQL, andyou 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 MySQLroot user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.Change the root password? [Y/n] n

... skipping.

By default, a MySQL installation has an anonymous user, allowing anyoneto log into MySQL without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.

Remove anonymous users? [Y/n] y

... Success!

Normally, root should only be allowed to connect from 'localhost'. Thisensures 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 canaccess. This is also intended only for testing, and should be removedbefore 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 farwill take effect immediately.

Reload privilege tables now? [Y/n] y

... Success!

Cleaning up...All done!

If you've completed all of the above steps, your MySQLinstallation should now be secure.

Thanks for using MySQL!

或者对于本地测试环境直接可以使用以下命令来初始化root密码：

# mysqladmin -u root password [your_password_here]

4.本地连接 Mysql

$ mysql -u root -p$ mysql -h localhost -u root -p

5.创建数据库，创建新用户及授予权限

## 创建数据库 flaskr ##mysql> CREATE DATABASE flaskr; ## 创建用户 flaskr_user ##mysql> CREATE USER 'flaskr_user'@'192.168.1.102' IDENTIFIED BY 'passwordxxx'; ## 授予权限 ##mysql> GRANT ALL ON flaskr.* TO 'flaskr_user'@'192.168.1.102'; ## FLUSH PRIVILEGES, reload the GRANT TABLES ##mysql> FLUSH PRIVILEGES;本文出自 “创十三” 博客，请务必保留此出处http://liucw.blog.51cto.com/6751239/1154967
