Not able to install MYSQL on EC2

Question

New to AWS, i have installed a EC2 instance (in Amazon Linux 2023 eng) and using EC2 Instance Connect, i have connected to the instance.
Also trying to install the MySQL in the server to be able to connect to RDS.
Command which i am using:

**mysql
-bash: mysql: command not found**

**sudo yum install mysql -y**

Error: *Failed to download metadata for repo 'amazonlinux': Cannot prepare internal mirrorlist: Curl error (28): Timeout was reached*

*Ignoring repositories: amazonlinux, kernel-livepatch
No match for argument: mysql
Error: Unable to find a match: mysql*

Accepted Answer

AL2023 is bundled with MariaDB 10.5. To install

```
sudo dnf install mariadb105-server
```

Root login in mariadb 10.4.3 and higher uses [unix_socket](https://mariadb.com/kb/en/authentication-plugin-unix-socket/). To connect
```
sudo mysql -uroot -p
```
Press enter when prompt for password

Also, this error `Failed to download metadata for repo 'amazonlinux': Cannot prepare internal mirrorlist: Curl error (28): Timeout was reached` indicates network connectivity errors to yum repository. Are you able to access internet from EC2 instance?
 You need to fix this, i.e. able to ping and connect to the internet, e.g.

```
%% ping al2023-repos-us-east-1-de612dc2.s3.dualstack.us-east-1.amazonaws.com
PING s3-r-w.dualstack.us-east-1.amazonaws.com (52.217.82.176) 56(84) bytes of data.
64 bytes from s3-us-east-1-r-w.amazonaws.com (52.217.82.176): icmp_seq=1 ttl=221 time=226 ms
64 bytes from s3-us-east-1-r-w.amazonaws.com (52.217.82.176): icmp_seq=2 ttl=221 time=226 ms
```
Check your EC2 security group and associated route table.
