How To Set Up A Multi Machine System¶

Setting up a multi-machine Shield system is a process thoroughly described in here.

Here is a quick guide that summarizes the required steps:

To install 3 identical Shield Servers (containing ALL components)

On the 2 additional servers, follow the same pre-requisies as above and then run:

sudo wget https://ericom-tec.ashisuto.co.jp/shield/prepare-node.sh
sudo chmod +x prepare-node.sh
sudo ./prepare-node.sh

From the first (leader) machine, run the following command to configure updates:
```
sudo /usr/local/ericomshield/update.sh sshkey
```

Note

When prompted for SSH password, this is the password used to access the Linux machine.

Create the cluster (from the leader machine). Run the following command:

sudo /usr/local/ericomshield/addnodes.sh -ips xx.xx.xx.xx,yy.yy.yy.yy --management --shield-core --browser

where xx.xx.xx.xx,yy.yy.yy.yy are the IP’s of the 2nd and 3rd machines.

The setup is complete.

Advanced Configuration¶

To setup Servers with only browser containers, follow the steps described above but replace step 3 with the following command:
```
sudo /usr/local/ericomshield/addnodes.sh -ips xx.xx.xx.xx,yy.yy.yy.yy --browser
```
To remove the browser containers from an existing management server, run the following commands (from the management server):
```
sudo /usr/local/ericomshield/status.sh -n
```
The above command will list the servers that are part of the cluster, note the node name and run:
```
sudo ./nodes.sh -remove-label <NodeName> browser
```
Where (NodeName) is the name of the machine where the browser containers are being removed.
