Remote Installation of Linux Servers using SSH

Perform remote installation using SSH to add the Linux agent in multiple servers in one go.

Prerequisites:

• Ensure SSH server is running in the target server
• The server from which the installation is performed should be of 64-bit type. However, the target servers can be of 32-bit or 64-bit type  

Procedure:

1. Execute the following command in the terminal to download and install the remote installer:

   wget https://staticdownloads.site24x7.com/server/Site24x7remoteinstaller.sh
   bash Site24x7remoteinstaller.sh -i -automation=true -key=<Device Key>

2. By default, two files, readme.txt and servers.txt will be created. Based on the authentication method, edit the servers.txt file:
   • For a common root password/PEM file path authentication, add the param "-password=<server password>" or "-pemfilepath=<PEM file path>" to the above command and enter the hostname and username in the following format:
     Eg:
     

     #Header: hostname, username 
                      SERVER1,root 
                      SERVER2,root 

   • If in case some of the servers have a different password/PEM file path other than the root password/PEM file path, enter the hostname, username and the password/PEM file path in the following format:
     Eg:

     #Header: hostname,username,password
                      SERVER2,root,<server password>
     #Header: hostname,username,pemfile
                      SERVER2,root,<pemfilepath> 

3. Save the changes done in servers.txt file and rerun the command

To uninstall:
Execute the following command in the terminal to uninstall the agent:

sudo -E bash -c "$(curl -sL https://staticdownloads.site24x7.com/server/Site24x7remoteinstaller.sh)" readlink -u -key=<Device Key>

Tips:

• Ensure the first cell of your CSV file has "#Header" entered. Download a sample file.
• For password based SSH authentication, enclose the password in double quotes if it has a comma
  SERVER1,root,"pass,word"
