Install AWS CLI on Centos

 Today we will look at installing AWS CLI on Centos, i installed on one of the EC2 instances recently and will share the steps as below:

1. Download AWS CLI:

url "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"

2. Once downloaded, we need to install the zip, but first need to unzip. IN my case unzip was not installed on the host , hence i have downloaded and installed as below:

yum makecache

yum install unzip

3. Once done use unzip to unpack the downloaded bundle:

unzip awscli-bundle.zip

4. Next step is to install :

./awscli-bundle/install -b ~/bin/aws

........

You can now run: /root/bin/aws --version

Refer AWS documentation as well to get further clarity on the steps/versions

user@instance]# systemctl start mysqld

this should start mysql service

The temporary root password can be found in the mysql log file and that can be used to login to the server.

however in this version, when we login with the given root password it will ask to reset this using 'alter command'.
