Log in to the Linux server as the root user.

1.Run the mkdir command to create a directory under the /opt directory to place the installation package. For example, netbraintemp.

3.Run the cd /opt/netbraintemp command to navigate to the /opt/netbraintemp directory.

4.Download the installation package.

▪Option 1: If the Linux server has no access to the Internet, obtain the redis-linux-x86_64-rhel7-5.0.4-8.0.2.tar.gz file from NetBrain and then upload it to the /opt/netbraintemp directory by using a file transfer tool.  

▪Option 2: If the Linux server has access to the Internet, run the
wget <download link> command under the /opt/netbraintemp directory to directly download the redis-linux-x86_64-rhel7-5.0.4-8.0.2.tar.gz file from NetBrain official download site.

Note: Contact NetBrain Support Team to get the download link. The download link is case-sensitive.

Tip: Run the yum -y install wget command to install the wget command if it has not been installed on the server.

5.Run the tar -zxvf redis-linux-x86_64-rhel7-5.0.4-8.0.2.tar.gz command under the /opt/netbraintemp directory to extract installation files.

[root@localhost netbraintemp]# tar -zxvf redis-linux-x86_64-rhel7-5.0.4-8.0.2.tar.gz
redis/
redis/config/
...
redis/config/setup.conf
...
redis/install.sh
...

6.Run the cd redis/config/ command to navigate to the config directory.

7.Modify the parameters in the setup.conf file located under the config directory and save the changes. For how to modify the configuration file, refer to Editing a File with VI Editor.

[root@localhost config]# vi setup.conf

StunnelSentinelPort=7001

8.Run the cd .. command to navigate to the redis directory.

9.Run the ./install.sh script under the redis directory to install Redis.

10. Run the systemctl status redis command to verify whether its service starts successfully.

[root@localhost ~]# systemctl status redis
 redis.service - Redis
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)

 Memory: 7.7M
...

Note: When your disk space is insufficient for large amounts of logs, you can modify the log settings in the redis.conf file under the /etc/logrotate directory.

Tip: It is highly recommended to run the rm -rf /opt/netbraintemp/redis/config/setup.conf command to delete the setup.conf file from the server after Redis is successfully installed because the file may cause security vulnerability.
