Before you start

• Role: DevOps / Linux IT with root access on both hosts

• Two NMS Prime installations; Galera (or agreed SQL cluster) ready

• Package nmsprime-provha on master and slave

• Needs: Base, ProvBase, fuse-sshfs, autofs

Guides

1. First steps (roles & GUI)

1. Install nmsprime-provha on both hosts (yum install nmsprime-provha)

2. Set PROVHA__OWN_STATE=master or slave in /etc/nmsprime/env/provha.env; run php artisan config:cache

3. Open ProvHA Config in the GUI; set master IP, slave IP, DNS update passwords, rebuild interval

4. Confirm own state set and determined values match (GUI warnings if not)

2. DHCP failover sanity

1. Set addresses in /etc/dhcp-nmsprime/failover.conf (master/peer)

2. Ensure dhcpd.conf includes the failover file; open peer ports (e.g. 7911/tcp, 647/tcp) in firewalld

3. Rebuild DHCP config from master; check journalctl -u dhcpd for peer normal / balancing messages

4. Remember: DHCP may not answer until the peer is reachable during startup

3. Sync & rebuild slave

1. Establish SSH key access from master to slave

2. On master: php artisan provha:sync_ha_master_files

3. Confirm slave rebuild interval; run cleanup on slave as documented (provha:clean_up_slave)

4. Optional paths: Cacti sshfs/autofs and Icinga HA — follow the nested Installation page

Prime High Availability is the core package for the entire HA-, Failover- and Load-Balancing process in NMS PRIME. It will enable you to run all Applications with several million devices in a highly secure, redundant, and tested manner. For this purpose, we try to stick as close as possible to default Linux and open-source standards.

Pro hint: It is best used with a lot of excellent Linux IT guys, devops, engineers and assisted in a close fashion with our team.
