时间：2024-01-01 19:23:03
安装依赖
yum install -y libaio

下载

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -O mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
创建目录
mkdir -p /data/service/mysql

解压

tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.7.18-linux-glibc2.5-x86_64/* /data/service/mysql
创建用户组
groupadd mysql

useradd -g mysql -s /sbin/nologin mysql
修改权限
chown -R mysql:mysql /data/service/mysql
配置环境变量
cat <<EOF > /etc/profile.d/mysql.sh

export PATH=/data/service/mysql/bin:\$PATH

EOF
. /etc/profile
目录规划（由于mysql特殊，必须使用在/usr/local/mysql的路径才行，那么采取的方法是软链接，不建议直接安装到/usr/local/mysql的路径，迁移是个很麻烦的问题）

初始化

# 此时会输出临时密码，一定要记住

设置启动项目

chkconfig --add mysql.server

chkconfig mysql.server on
启动
service mysql.server start
重置root密码，此时关闭

类似以下信息：

Securing the MySQL server deployment.

Enter password for user root: 

The existing password for the user account root has expired. Please set a new password.

New password: 

Re-enter new password: 

VALIDATE PASSWORD PLUGIN can be used to test passwords

and improve security. It checks the strength of password

and allows the users to set only those passwords which are

secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: Y

There are three levels of password validation policy:

LOW    Length >= 8

MEDIUM Length >= 8, numeric, mixed case, and special characters

STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2

Using existing password for root.

Estimated strength of the password: 100

Change the password for root ? ((Press y|Y for Yes, any other key for No) : N

 ... skipping.

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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : Y

Success.

All done!

目的是：

  • 重置密码
  • 删除匿名用户
  • 关闭root用户的远程登录
  • 删除测试数据库
