PBM install TLDR for simple MongoDB replicaset

pbm_install_replicaset_tldr.md

• Install repo and packages
• Create mongodb user as per https://www.percona.com/doc/percona-backup-mongodb/initial-setup.html#configure-authentication-in-mongodb
• Configure storage - must be shared storage, not a problem with S3/Minio, NFS or similar with path based though - https://www.percona.com/doc/percona-backup-mongodb/storage-configuration.html#pbm-config-example-yaml
  • Test this with B2
• Install and setup agent, pbm cli
  • Agent is using /etc/default/pbm-agent with one line of config - PBM_MONGODB_URI="mongodb://pbmuser:secretpwd@localhost:27017/?authSource=admin&replicaSet=rs0"
  • pbm cli expects the same env variable to be setup - use .bash_profile or alias - root user/pbm user only
• Start agents and check with pbm status, should get something like this below

:~# pbm status

Cluster:
========
rs0:
 - rs0/192.168.33.30:27017: pbm-agent v1.4.1 OK
 - rs0/192.168.33.31:27017: pbm-agent v1.4.1 OK
 - rs0/192.168.33.32:27017: pbm-agent v1.4.1 OK

• Try creating a backup using pbm backup from any host in replicaset
• TODO - create a simple Ansible role to do all of the above.
