Preparing the Installation Package
Download link: https://download.redis.io/releases/redis-6.2.6.tar.gz
Download and install the package to /usr/local/soft
Write the script file install_redis.sh (CentOS version)
The content of the file is as follows:
#! /usr/bin/bash## Fully automated source code compilation and installation for any versionif [ ! -d "/usr/local/soft" ]then
echo "The folder does not exist, please create a folder and place the installation package here"
exit
