Steps and yum commands to install redis in CentOS system

When using the yum command to install redis in a Linux CentOS system, an error message appears:

[root@localhost install]# yum install redis
Loaded plugins: fastestmirror
Setting up Install Process
Determining fastest mirrors
 * base: mirrors.skyshe.cn
 * extras: mirrors.163.com

This is because the default installation source of centos is on the official centos.org, and Redis is in the third-party yum source, so it cannot be installed. For unofficial yum, it is recommended to use fedora’s epel warehouse

Use the following command to install the third-party library: yum install epel-release

Then install redis: yum install redis

Use the service redis start command to start the redis server:

[root@localhost etc]#service redis start Redirecting to /bin/systemctl start redis.service

Use ps -ef | grep redisView the redis process:

[root@localhost etc]# ps -ef | grep redis redis 47664 1 0 05:31 ? 00:00:00 /usr/bin/redis-server 127.0.0.1:6379 root 47808 45376 0 05:32 pts /0 00:00:00 grep –color=auto redis
