Ansible based installation

Install the Operating system
System
Root User Access is required during the installation.
SELinux will be disabled during the Ansible deployment and this will also require to reboot the Operating System.
User
Nodeum will define one user which needs ID : 1000. This ID is created automatically when the package is deployed. If a user already use these ID, you have to change their id :
$ usermod -u 1001 "username"
admin:x:1000:1000::/dev/null:/bin/false
It is the same for group, where group ID 1000 and group ID 1001 needs to be available. If group already use these ID, you have to change their id :
$ groupmod -g 1002 "groupname"
admin:x:1000:
Install & Update
To proceed with a Nodeum installation or an update, the following instructions must be performed.
An unlimited internet connection is necessary.
$ yum install wget
$ wget get.nodeum.io/public/nodeum-v1-9xx.tar.gz
$ tar -xvzf /root/nodeum-xxx.tar.gz
$ cd v1-9xx-xx
$ ansible-playbook check_install.yml
$ ansible-playbook install.yml
Once the ansible-playbook is fully installed, and it ends up with this screen.

It is important to notice that there is no failed result
Then Nodeum is now ready to use, you can access it through your browser at this URL: http://your nodeum ip address/
or via the DNS name.
Advanced Settings
Proxy requirement
If your network configuration requires a Proxy server to reach the internet, you need to configure the Proxy servers as follows:
$ vi /etc/environment
export http_proxy=http://xxxxx:[email protected]:8080
export https_proxy=http://xxxxx:[email protected]:8080
export ftp_proxy=http://xxxxx:[email protected]:8080
no_proxy=http://xxxxx:[email protected]:8080
For example, if your password is :
F@o:o!B#ar$
, the following export will not work
export http_proxy="http://user:F@o:o!B#[email protected]:8080"
Convert special characters to hexadecimal format, such as
In this example :
@ becomes %40,
: becomes %3A,
and so on.
(For example,https://www.online-toolz.com/tools/text-hex-convertor.php)
In our case, the password: F@o:o!B#ar$
is transformed to F%40o%3Ao%21B%23ar%24
The http_proxy
export is formatted as follows:
export http_proxy="http://user:F%40o%3Ao%21B%23ar%[email protected]:8080"
Network Interface
Service mapping
Each service can be bound to a specific network interface.
After updating the inventory files to match your desired mapping, simply reapply the Ansible
Within the extracted Nodeum installation package, you will find a file /inventory/hosts_vars/srv1
.
This file contains various configurations and settings to be applied to host.
A section exists for defining the service
By default, the iface_name
parameter uses the main network interface but it can be overwritten.
# If there is no default network interface defined or you want to override it
# iface_name: eth0
Afterward, in the same file, you can find different parameters to bind a list of services to a specific interface name.
# Specific name of interface for each services. Default to iface_name
# or default network interface) if undefined
# smb_iface_name: eth0
# nfs_iface_name: eth0
# rails_iface_name: eth0
# zookeeper_iface_name: eth0
# solr_iface_name: eth0
# catalog_indexer_iface_name: eth0
Description of each parameter :
smb_iface_name
SAMBA
nfs_iface_name
NFS
rails_iface_name
RAILS
solr_iface_name
SOLR
catalog_iface_name
CATALOG INDEXER
