Cluster Manipulation Scripts

This repository contains a set of Ansible playbooks to perform common cluster management tasks.

├── playbooks
├── config.yml
└── development

Put relevant Debian package files into distr/ directory:

    distr
    └── mc_4.8.18-1_amd64.deb

Put j2-conf files into files/ directory:

    files
    ├── nginx.conf.j2
    └── ntp.conf.j2

The include/ directory for vars which may be use in playbooks:

    include
    └── vars.yml

The logs/ directory for logs which fetched from hosts

The playbooks/ directory for playbook instructions which will be run on each server:

    playbooks/
    ├── copy-logs-from-servers.yml
    ├── mc-deb-install.yml
    ├── mount-storage.yml
    ├── nginx-install.yml
    ├── ntp-install.yml
    ├── reboot.yml
    ├── remove_files.yml
    ├── replace-txt.yml
    ├── service.yml
    └── uri.yml

The config.yml for temporary variables which use on playbooks

The development is inventory hosts where added ip-hosts and user access data

Install or Update MC

Put relevant Debian package files into distr/ directory:

    distr
    └── mc_4.8.18-1_amd64.deb

Update and commit ./config.yml file:

    mc_version: '4.1.1.7637'

Run mc-deb-install playbook:

ansible-playbook -v -i development playbooks/mc-deb-install.yml

To limit the range of nodes to which playbook applies use --limit option:

ansible-playbook -v -i development playbooks/mc-deb-install.yml --limit "host[1:3]"

Install or Update NTP

Install ntp via apt. Run ntp-install playbook:

ansible-playbook -v -i development playbooks/ntp-install.yml

To limit the range of nodes to which playbook applies use --limit option:

ansible-playbook -v -i development playbooks/ntp-install --limit "host[1:3]"

Collect Logs

To collect Logs use copy-logs-from-servers playbook:

ansible-playbook -v -i development playbooks/copy-logs-from-servers.yml

Logs will be downloaded into ./logs directory, separate file for each node:

    logs
    ├── 20200927T130808_host1_logs.tar.xz
    ├── 20200927T130808_host2_logs.tar.xz
    └── 20200927T131141_host3_logs.tar.xz

NOTE: if no --limit is used logs will be collected from the entire cluster, which can be very time consuming.
