centos安装mysql8.0教程
不废话,直接开始安装,环境自己检查,我使用的是centos7.6,已卸载所有关于mysql的环境
安装mysql源
rpm -Uvh https://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpm
开始安装
yum --enablerepo=mysql80-community install mysql-community-server
如果环境很多依赖包没有,我的环境大概有500多M
启动mysql服务
systemctl start mysqld && systemctl enable mysqld

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) : yes
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!
