LXD Container

Create LXD container

1. cd ~/projects/scripts/bash-scripts/lxc/
2. ./lxc-create-basic-ubuntu-container.sh automata-all 10.104.71.60 /projects/code/automata-projects/automata-deploy
3. lxc.list

Add these aliases to vi ~/bash/bash-profile-aliases/aliases/bash-projects

# automata all
alias automata-all.lxc.start="lxc.start-container automata-all"
alias automata-all.lxc.stop="lxc.stop-container automata-all"
alias automata-all.lxc.run-in="lxc.run-in.container automata-all"
alias automata-all.project="cd ~/projects/code/automata-projects/automata-deploy"

Remember to run source ~/.bashrc

Container Info

• lxc image list images: ubuntu/22.04 amd64

Container Manipulation

• lxc stop automata-all

Redis (Container)

Redis Install

1. sudo apt update
2. sudo apt install redis

Redis Config

1. sudo vi /etc/redis/redis.conf
2. Change to bind 10.104.71.60 127.0.0.1 (allow second IP for accessing on host by default)
3. sudo systemctl restart redis-server

Redis Time Series

Prerequisites

1. sudo apt install make
2. sudo apt install python3-dev

Build & Install RedisTimeSeries Module

This is a module, which needs to be built, installed and configured into the Redis server.

1. mkdir -p ~/software/redis/module
2. cd ~/software/redis/module
3. git clone --recursive https://github.com/RedisTimeSeries/RedisTimeSeries.git
4. cd ~/software/redis/module/RedisTimeSeries
5. make setup
6. make build
7. sudo mkdir /etc/redis/modules
8. sudo mv bin/linux-x64-release/redistimeseries.so /etc/redis/modules/ (get the actual file not symbolic linked one)
9. sudo vi /etc/redis/redis.conf
10. Add the line loadmodule /etc/redis/modules/redistimeseries.so to redis.conf

Verify Redis log

less /var/log/redis/redis-server.log should see:

192:M 26 Jul 2022 13:00:44.751 * <timeseries> RedisTimeSeries version 999999, git_sha=7c671138969c9dd9edcd9825427a9d360ac147e7

192:M 26 Jul 2022 13:00:44.759 * Module 'timeseries' loaded from /etc/redis/modules/redistimeseries.so

Verify via redis cli

1. redis-cli
2. INFO Modules

Should see:

# Modules
module:name=timeseries,ver=999999,api=1,filters=0,usedby=[],using=[],options=[]

Redis Port (outside container)

• nc -zv 10.104.71.60 6379

Stop and start the container to ensure redis, has installed correctly.

Backup (Redis)

1. CONFIG get dir (in redis-cli) Tells where the dump file is located
2. SAVE
3. /var/lib/redis (should be dump.rdb)
4. sudo systemctl status redis-server
5. sudo systemctl stop redis-server
6. sudo cp /var/lib/redis/dump.rdb BACKUP-DIR

Restore (Redis)

1. sudo systemctl stop redis-server
2. sudo cp BACKUP-DIR /var/lib/redis/dump.rdb
3. sudo systemctl start redis-server
