Instalar redis
1. Install pre-requisities
`sudo apt-get install build-essential tcl`
2. Install Redis
```
cd /tmp
curl -O http://download.redis.io/redis-stable.tar.gz
tar xzvf redis-stable.tar.gz
cd redis-stable
make
make test
sudo make install
```
3. Configure Redis
```
sudo mkdir /etc/redis
sudo cp /tmp/redis-stable/redis.conf /etc/redis
sudo nano /etc/redis/redis.conf
```
In the file, change the `supervised` directive`s value to `systemd`.
```
...
supervised systemd
...
```
Next, specify the working directory for Redis. This is the directory that Redis will use to dump persistent data. We can use `/var/lib/redis`
```
...
dir /var/lib/redis
...
```
Save and close the file.
4. Configure systemd to start Redis on boot
`sudo nano /etc/systemd/system/redis.service`
Copy the contents of [this gist](https://gist.github.com/hackedunit/14690b6174708d3e83593ce1cdfb4ed8) to the file, save and close.
5. Create Redis user, group and directories
```
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. Start the Redis service and set Redis to start on boot
```
sudo systemctl start redis
sudo systemctl enable redis
```
