How to install Redis on Ubuntu 16.04?

I think always is better (and simpler) to install from main repos as first option if you don't have any special requirements.

The package you are searching for is named redis-server. You can check its package info with apt show redis-server.

Also yo can search all packages mentioning redis with apt search redis, or even do some simple filtering using grep, use apt search redis | grep php to search for php-redis or related package(s) for example.

So, you can simply run:

sudo apt install redis-server

on your terminal, to install a fully working redis(server) environment.

If you have any special requirements, you always can build from source and install as @George posted on his answer.

Hope it helps.

To install redis follow these steps:

Set up a non-root user with sudo privileges

Install build and test dependencies:

sudo apt update
sudo apt full-upgrade
sudo apt install build-essential tcl

Set up redis:
1. Download latest copy via this link or with this
```
curl -O http://download.redis.io/redis-stable.tar.gz
```
2. Create a temporary folder for it in say your /home/username/redis-stable directory
3. Move into created folder and extract it
```
tar xzvf redis-stable.tar.gz
```
4. Change into the folder cd redis-stable and build it with
```
make
make test
sudo make install
```
Configure redis:
1. Create configuration directory:
```
sudo mkdir /etc/redis
```
2. Move sample redis configuration file:
```
sudo cp /home/george/redis-stable/redis.conf /etc/redis
```
3. Edit the file:
```
sudo nano /etc/redis/redis.conf # or with any other text editor
```
4. Make two changes there:
  supervised no to supervised systemd
  dir to dir /var/lib/redis # for persistent data dump

Set up the systemd unit file:

sudo nano /etc/systemd/system/redis.service

Add the text:

[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

Set up redis user, groups and directories:

create redis user and group with same ID but no home directory:

sudo adduser --system --group --no-create-home redis   
sudo mkdir /var/lib/redis   # create directory
sudo chown redis:redis /var/lib/redis   # make redis own /var/lib/redis
sudo chmod 770 /var/lib/redis   # adjust permission

Test redis:

Start redis service:
```
sudo systemctl start redis
```

Check status:

systemctl status redis

Result of status if started successfully:

Output
● redis.service - Redis Server
 Loaded: loaded (/etc/systemd/system/redis.service; enabled; vendor preset: enabled)

 Process: 3115 ExecStop=/usr/local/bin/redis-cli shutdown (code=exited, status=0/SUCCESS)

Test instance:
1. Connect:
```
redis-cli
```
2. Test connectivity at prompt:
```
127.0.0.1:6379> ping   # result PONG
```
3. Check ability to set keys:
```
127.0.0.1:6379 set test "It's working!"  # result ok
```
4. Get the key just set:
```
127.0.0.1:6379 get test  # result "It's working!"
```
5. Exit redis:
```
127.0.0.1:6379 exit
```
6. Restart redis and then re-run steps 1, 4, and 5 to connect with the client again and confirm that your test value is still available, hence it's working as expected:
```
sudo systemctl restart redis
```

Enable redis to start at boot:
```
sudo systemctl enable redis
```
