Instalando REDIS

To install redis follow these steps:

1 - Set up a non-root user with sudo privileges

2 - Install build and test dependencies:

sudo apt update 

sudo apt full-upgrade 

sudo apt install build-essential tcl 

3 - Set up redis:

Download latest copy via this link or with this

curl -O http://download.redis.io/redis-stable.tar.gz 

4 - Create a temporary folder for it in say your /home/username/redis-stable directory

Move into created folder and extract it

tar xzvf redis-stable.tar.gz 

Change into the folder cd redis-stable and build it with

make make test sudo make install 

5 - Configure redis:

Create configuration directory:

sudo mkdir /etc/redis 

Move sample redis configuration file:

sudo cp /home/george/redis-stable/redis.conf /etc/redis 

Edit the file:

sudo nano /etc/redis/redis.conf # or with any other text editor 

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:

1. Start redis service:
   1. sudo systemctl start redis
2. Check status:
   1. systemctl status redis
   2. Result of status if started successfully:
   3. Output ● redis.service - Redis Server Loaded: loaded (/etc/systemd/system/redis.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2016-05-11 14:38:08 EDT; 1min 43s ago Process: 3115 ExecStop=/usr/local/bin/redis-cli shutdown (code=exited, status=0/SUCCESS) Main PID: 3124 (redis-server) Tasks: 3 (limit: 512) Memory: 864.0K CPU: 179ms CGroup: /system.slice/redis.service └─3124 /usr/local/bin/redis-server 127.0.0.1:6379
3. Test instance:
   1. Connect:
      1. redis-cli
   2. Test connectivity at prompt:
      1. 127.0.0.1:6379> ping # result PONG
   3. Check ability to set keys:
      1. 127.0.0.1:6379 set test "It's working!" # result ok
   4. Get the key just set:
      1. 127.0.0.1:6379 get test # result "It's working!"
   5. Exit redis:
      1. 127.0.0.1:6379 exit
   6. Restart redis and then re-run steps 1, 4, and 5:
      1. sudo systemctl restart redis
1. Enable redis to start at boot:
   1. sudo systemctl enable redis
