Redis Cluster Creation OSS and Enterprise Redis OSS/Enterprise Installation and Configuration Exercise

 

1. Download and install standalone Redis OSS, version 6.x, on GCP Instance 1.

Step 1: download the Redis OSS from https://redis.io/download Step 2: run the following commands

$ wget https://download.redis.io/releases/redis-6.2.3.tar.gz $ tar xzf redis-6.2.3.tar.gz $ cd redis-6.2.3 $ make

Started the server using the following command

$ src/redis-server

Started the Redis CLI using the following command for testing the connectivity

$ src/redis-cli

redis> set foo bar OK redis> get foo "bar" 

2. Use RedisLabs' memtier-benchmark utility to load some data into a standalone Redis DB on Redis OSS.

Step 1: Installing the RedisLabs memtier-benchmark utility apt-get install build-essential autoconf automake libpcre3-dev libevent-dev pkg-config zlib1g-dev libssl-dev

Step 2: Clone the git repository git clone https://github.com/RedisLabs/memtier_benchmark.git cd memtier_benchmark

Step3: Run the autoreconf and make the application autoreconf -ivf ./configure make

Step4: verify version of meatier-benchmark

./memtier_benchmark --version

Step 5: imported some sample data from https://github.com/redis-developer/redis-datasets/blob/movie-dataset/movie-database/import_actors.redis Pushed into the Redis cluster 

3. Download and install Redis Enterprise GA version on EC2 Instance 2 using the no DNS option.    A) Use "wget "

Installation of Redis Enterprise:

Verifying the OS: its Ubuntu 18.04.1 LTS bionic trainee@interview-2:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.1 LTS Release: 18.04 Codename: bionic

Step1: Downloaded the comparable software as the above provided links is of incorrect (Xenial vs Bionic)

redislabs-6.0.20-69-bionic-amd64.tar

Step 2: Extracted the software

trainee@interview-2:$ ls redislabs-6.0.20-69-bionic-amd64.tar trainee@interview-2:$ chmod -R 777 . trainee@interview-2:~$ ls redislabs-6.0.20-69-bionic-amd64.tar

trainee@interview-2:~$ tar -xvf redislabs-6.0.20-69-bionic-amd64.tar

Step 3: installed the software using install.sh script

trainee@interview-2:~$ sudo ./install.sh

Step 4: Verified the installation is completed

Summary:

ALL TESTS PASSED.

2021-05-16 22:59:54.156 [!] Please logout and login again to make sure all environment changes are applied. 2021-05-16 22:59:54.158 [!] Point your browser at the following URL to continue: 2021-05-16 22:59:54.162 [!] https://:8443 

Step 5: Access the URL with in the console

trainee@interview-2:~$ curl https://:8443 -kv 

Note: I’m not able to access link from the browser as the port 53 is occupied, so performed the following steps to resolve it as mentioned in the requirement

Step 6: Copy the steps from the following link and run it. https://docs.redislabs.com/latest/rs/getting-started/

1. Run: sudo vi /etc/systemd/resolved.conf
2. Add DNSStubListener=no as the last line in the file and save the file.
3. Run: sudo mv /etc/resolv.conf /etc/resolv.conf.orig
4. Run: sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
5. Run: sudo service systemd-resolved restart

Step 7: Now access the link Redis enterprise link on https://:8443/#/setup 

4. Within Redis Enterprise, create a single node cluster and an empty database.

Step1: Setting up the cluster using default options  Step2: Don’t have the license key so using the trail version  Step 3: Setting up the default admin credentials using my personal id  Step 4: Creating a empty database



5. Enable "Replica Of" between the Redis Enterprise and the Redis OSS databases - where your Source DB is "Redis OSS" and your Target DB is "Redis Enterprise".

6. Write a small script/program using a language of your choice (e.g. Java, Python, Ruby, Go, C#, or JavaScript) to complete the following:    A) Insert the values 1-100 into the Redis OSS database on GCP Instance 1.    B) Read and print them in a reverse order from the Redis Enterprise database on GCP Instance 2.

import redis

r = redis.Redis( host='', port=) i=1 while(i < 101): r.rpush('demolist', i) i += 1 #Print out the values from 1 - 100
print(r.lrange('demolist', 0, -1))

python script.py [‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’, ‘10’, ‘11’, ‘12’, ‘13’, ‘14’, ‘15’, ‘16’, ‘17’, ‘18’, ‘19’, ‘20’, ‘21’, ‘22’, ‘23’, ‘24’, ‘25’, ‘26’, ‘27’, ‘28’, ‘29’, ‘30’, ‘31’, ‘32’, ‘33’, ‘34’, ‘35’, ‘36’, ‘37’, ‘38’, ‘39’, ‘40’, ‘41’, ‘42’, ‘43’, ‘44’, ‘45’, ‘46’, ‘47’, ‘48’, ‘49’, ‘50’, ‘51’, ‘52’, ‘53’, ‘54’, ‘55’, ‘56’, ‘57’, ‘58’, ‘59’, ‘60’, ‘61’, ‘62’, ‘63’, ‘64’, ‘65’, ‘66’, ‘67’, ‘68’, ‘69’, ‘70’, ‘71’, ‘72’, ‘73’, ‘74’, ‘75’, ‘76’, ‘77’, ‘78’, ‘79’, ‘80’, ‘81’, ‘82’, ‘83’, ‘84’, ‘85’, ‘86’, ‘87’, ‘88’, ‘89’, ‘90’, ‘91’, ‘92’, ‘93’, ‘94’, ‘95’, ‘96’, ‘97’, ‘98’, ‘99’, ‘100’]
