Install Fsched CE

Fsched CE must be installed manually. This installation process uses Ansible-based scripts to quickly deploy an Fsched CE cluster.

Installation Steps

Confirm the installation prerequisites

Confirm that the cluster nodes already have:
- A shared home directory
- Unified authentication
- Time synchronization
Confirm that the Ansible host already has:
- Ansible installed
- Access to the cluster nodes through the root user and an SSH key
Extract the Fsched remote installation package on the Ansible host

Parameters:
- VERSION: the version of the Fsched remote installation package
```
tar zxvf fsched-ce-${VERSION}-remote-install.tar.gz
cd fsched-ce-${VERSION}-remote-install/ce-install
```

Update the hostname and IP of each cluster node in inv.yml based on your cluster information

Example:

vi inv.yml

head:
    hosts:
        partition-qhkjh-1:              # specify hostname of head
            ansible_user: root
            ansible_host: 10.0.10.2     # specify ip address of head
compute:
    hosts:
        partition-qhkjh-2:              # specify hostname of compute 1
            ansible_user: root
            ansible_host: 10.0.10.4     # specify ip address of compute 1
        partition-qhkjh-3:              # specify hostname of compute 2
            ansible_user: root
            ansible_host: 10.0.10.3     # specify ip address of compute 2

Run the installation script

Parameters:
- SSH_KEY_PATH: the path to the SSH key file used to log in to the cluster nodes
- SOURCE_PATH: the full path of fsched-ce-${VERSION}.tar.gz under the fsched-ce-${VERSION}-remote-install directory
```
ansible-playbook --private-key ${SSH_KEY_PATH} --inventory inv.yml --extra-vars "source_path=${SOURCE_PATH}" fsched-ce.yml
```
