CentOS7安装Mysql8.0.20步骤:
https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-20.html
官网下载有时速度比较慢,直接点击链接也可以下载:mysql 8.0.20
官网下载8.0.20Mysql包(bundle版本)
1.创建mysql文件夹:
[root@localhost ~]# mkdir /usr/local/mysql
[root@localhost ~]# cd /usr/local/mysql/
将下载的mysql包放在创建的MySQL文件夹内:
[root@localhost mysql]# ll

mysql的安装版MD5码查看是否和官网上的相对应:
[root@localhost mysql]# md5sum mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
c8d062c1f74d9aab7dbdd5300b202b6e mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
将mysql的包解压得到几个内安装包:
[root@localhost mysql]# tar -xvf mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
mysql-community-libs-8.0.20-1.el7.x86_64.rpm
