Step 4 :
Install rpm to local servers
use yum localinstall

Step 5 :
Check which version of community severe available on local server
1 2 3 4 |
[root@ip-172-31-39-223 ec2-user]# yum repolist enabled | grep "mysql.*-community*" mysql-connectors-community/x86_64 MySQL Connectors Communi 131 mysql-tools-community/x86_64 MySQL Tools Community 100 mysql80-community/x86_64 MySQL 8.0 Community Serv 145 |
we have mysql 8.0 available on local server
if we want to install 8 directly we can use yum install mysql-community server
In case if we want lower version of mysql (5.7)
Then follow below steps
Step 6 :
Enable 5.7 community server on local server

We have both 5.7 and 8.0 are available so disable MySQL 8.0 community server
Step 7:
Disable MySQL 8.0 Community Server
