Problem scenario
You want to deploy (install and configured) Redis (an in-memory data store) to an Ubuntu 16.x or an 18.x server. What do you do?
Solution
These directions were based on this external posting as they appeared on 3/25/18.
1. Install some dependencies with these two commands:
sudo apt-get -y update
sudo apt-get -y install build-essential tcl
2. Download the source media with this command:
curl http://download.redis.io/redis-stable.tar.gz > /tmp/redis-stable.tar.gz
3. Install Redis with these commands:
sudo cp /tmp/redis-stable.tar.gz /opt/redis-stable.tar.gz
cd /opt/
sudo tar xzvf redis-stable.tar.gz
cd redis-stable
sudo make
sudo make test
sudo make install
4.a. Configure Redis with these commands:
sudo mkdir /etc/redis
sudo cp /opt/redis-stable/redis.conf /etc/redis
sudo vi /etc/redis/redis.conf # find the uncommented "supervised" stanza and change the word "no" to "systemd"
4.b. Configure Redis by creating a redis.service file.
sudo vi /etc/systemd/system/redis.service # To create this file
# Insert these lines below to include "[Unit]" (as the first line) and
"WantedBy=multi-user.target" (as the last line):
[Unit]
Description=Redis In-Memory Data Store
After=network.target
[Service]
User=redis
Group=redis
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/local/bin/redis-cli shutdown
Restart=always
[Install]
WantedBy=multi-user.target
5. Run these four commands to create the proper user, directory, and permissions settings:
sudo adduser --system --group --no-create-home redis
sudo mkdir /var/lib/redis
sudo chown redis:redis /var/lib/redis
sudo chmod 770 /var/lib/redis
6. Run these two commands to start up Redis:
sudo systemctl start redis
sudo systemctl status redis
7. Verify the installation with this command: redis-server --version
