Install a package

#linux

As per new application requirements shared by the Nautilus project development team, serveral new packages need to be installed on all app servers in Stratos Datacenter. Most of them are completed except for rsync.

Therefore, install the rsync package on all app-servers.

Solution

Step 1: Connect to Each App Server and Install rsync

App Server 1 (stapp01) - User: tony 

ssh tony@stapp01
# Password: Ir0nM@n
sudo su -
# Password: Ir0nM@n
yum install -y rsync
exit
exit
Enter fullscreen mode Exit fullscreen mode

App Server 2 (stapp02) - User: steve 

ssh steve@stapp02
# Password: Am3ric@
sudo su -
# Password: Am3ric@
yum install -y rsync
exit
exit
Enter fullscreen mode Exit fullscreen mode

App Server 3 (stapp03) - User: banner 

ssh banner@stapp03
# Password: BigGr33n
sudo su -
# Password: BigGr33n
yum install -y rsync
exit
exit
Enter fullscreen mode Exit fullscreen mode

One-Line Commands

App Server 1 (stapp01): 

echo 'Ir0nM@n' | ssh tony@stapp01 "sudo -S yum install -y rsync"
Enter fullscreen mode Exit fullscreen mode

App Server 2 (stapp02): 

echo 'Am3ric@' | ssh steve@stapp02 "sudo -S yum install -y rsync"
Enter fullscreen mode Exit fullscreen mode

App Server 3 (stapp03): 

echo 'BigGr33n' | ssh banner@stapp03 "sudo -S yum install -y rsync"
Enter fullscreen mode Exit fullscreen mode

Using Heredoc (Recommended)

App Server 1: 

ssh tony@stapp01 << 'EOF'
echo 'Ir0nM@n' | sudo -S bash -c '
echo "=== Installing rsync on stapp01 ==="
yum install -y rsync
echo "✓ rsync installed"
rsync --version | head -1
'
EOF
Enter fullscreen mode Exit fullscreen mode

App Server 2: 

ssh steve@stapp02 << 'EOF'
echo 'Am3ric@' | sudo -S bash -c '
echo "=== Installing rsync on stapp02 ==="
yum install -y rsync
echo "✓ rsync installed"
rsync --version | head -1
'
EOF
Enter fullscreen mode Exit fullscreen mode

App Server 3: 

ssh banner@stapp03 << 'EOF'
echo 'BigGr33n' | sudo -S bash -c '
echo "=== Installing rsync on stapp03 ==="
yum install -y rsync
echo "✓ rsync installed"
rsync --version | head -1
'
EOF
Enter fullscreen mode Exit fullscreen mode

ssh tony@stapp01 "rsync --version | head -1"
ssh steve@stapp02 "rsync --version | head -1"

# Check package installation
