Requirements-
- Linux Machine with CentOS 6/7 with Root Permissions
- Internet Connection
Procedure to Compile Redis from Source -
1. Install some required packages (needs root permissions)
sudo yum install wget make gcc tcl -y
2. Download the latest stable source for Redis from official release directory.
wget http://download.redis.io/releases/redis-stable.tar.gz
3. Extract tarball
tar -xvf redis-stable.tar.gz
4. Run the following commands one by one to compile Redis from source. Please note that make commands below will take some time to complete, so keep patience
cd redis-stable cd deps make hiredis lua jemalloc linenoise cd .. make make test
5. If make test commands show output as below then you have successfully compiled Redis.
6. If you want to install for all users on your machine run the following command or else skip it (root permissions required)
sudo make install
Install init Script
We need init configuration so that redis-server should start itself on boot and no manual commands are needed by the user.
Note – We need root to create init Script
1. Goto your redis-stable directory where you have compiled Redis from source using the above steps
cd /full/path/redis-stable
cd src
2. Run the following command to get full path of your Redis dir, which I needed when creating init Script
pwd
As is above photo for me full path is /home/username/redis-stable
3. Goto utils directory in redis-stable
cd utils
4. Run install_server.sh script as root
sudo ./install_server.sh
It will ask you some details while creating init script. To keep default just press ENTER Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default – /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default – /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379]
Selected default – /var/lib/redis/6379
Please select the redis executable path [] /home/username/redis-stable/src/redis-server
In my config, I have used everything default and have customized only the ‘redis executable path’, which means that we have to define the path where we have compiled the Redis ourselves.
So, now we will use the full path of redis-stable dir generated in Step #2 above and for me redis is compiled inside ‘src’ dir so for me redis executable path is /home/username/redis-stable/src/redis-server
Press enter after entering the correct path and it will show you the selected configuration, just cross check and press ENTER to confirm.
Note- Users who have installed it as root don’t need to change the ‘redis executable path’
5. If everything goes correct then install_server script will show success message on your terminal window.
6. Now we have to start the service created by init script which needs root permissions
For CentOS 6 run
service redis_6379 start
For CentOS 7 run
systemctl start redis_6379
Note – If you have used custom port then your service name should be different.
Create alias for redis-cli
This is only needed if you have installed for the specific user and not as root
1. Edit .bashrc file for alias
nano ~/.bashrc
2. Paste the following lines at the end
alias redis-cli=~/redis-stable/src/redis-cli alias redis-server=~/redis-stable/src/redis-server
Note- Please adjust if your redis-stable dir in not in root of your user.
3. Apply .bashrc changessource ~/.bashrc
Test redis
1. Run redis-cli using following command and run proceeding commands to test redis.
redis-cli > set welcome “Hello from RootAdminz” > get welcome
So, we have finished the Installation for Redis on CentOS Machine.
