Installing from source
Prerequisites
sudo apt-get update
sudo apt-get install build-essential tcl
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
Config for installing from source
sudo mkdir /etc/redis
sudo cp /tmp/redis-stable/redis.conf /etc/redis
sudo nano /etc/redis/redis.conf
Update above file for following line
supervised systemd

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
Create Redis user and dirs
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
Start and Test Redis
sudo systemctl start redis
sudo systemctl status redis
To install jitsi meet we are going do setup for following components
Java dependency
Check if jdk installed on your ubuntu, it must be > 1.7
java -version javac -version
Both above must be greater than 1.7
sudo add-apt-repository ppa:webupd8team/java -y
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default
Check again with same commands
java -version javac -version
If versions are > 1.7 we are ready to go ahead.
If you have java installed already, but it points to some older version, you can select proper version using following
sudo update-alternatives --config java sudo update-alternatives --config javac
