MySQL 我的最爱
Step1 安装
1 $ sudo yum install mysql mysql-server
Step2 配置
1 $ sudo vim /etc/my.cnf
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # 设置编码格式 default-character-set=utf8 # 设置不区分大小写 lower_case_table_names=1 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [mysql] # 设置编码格式 default-character-set=utf8
Step3 启动服务
1 # 设置MySQL服务随系统启动自启动
2 $ sudo chkconfig mysqld on
3 # 确认MySQL自启动，如果2--5为on的状态就OK
4 $ sudo chkconfig --list mysqld
5 mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
6 # 启动MySQL服务
7 $ sudo /etc/rc.d/init.d/mysqld start
8 Initializing MySQL database: [ OK ]
9 Starting MySQL: [ OK ]
Step4 环境设定
为 MySQL 的 root 用户设置密码，MySQL 在刚刚被安装的时候，它的 root 用户是没有被设置密码的。
1 $ 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): <-- 输入系统 root 密码 OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n] <-- ENTER New password: <-- 你的 MySQL root 密码 Re-enter new password: <-- 你的 MySQL root 密码 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. # 删除匿名用户，在MySQL刚刚被安装后，存在用户名、密码为空的用户。这使得数据库 服务器有无需密码被登录的可能性。为消除隐患，将匿名用户删除。 Remove anonymous users? [Y/n] <-- ENTER ... 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] <-- ENTER ... 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. # 删除人人都能访问的 test 数据库 Remove test database and access to it? [Y/n] <-- ENTER - 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] <-- ENTER ... Success! Cleaning up... All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL!
Step5 测试
1 # 用 root 用户通过密码登录
2 $ mysql -u root -p
3 Enter password: <-- 输入密码
4 Welcome to the MySQL monitor. Commands end with ; or \g.
