中间件的选择，有时候要结合多方面的，比如JDK,比如redis（缓存），本次项目选择了redis目前最新版本，，接下来安装试试
一、下载地址：
https://redis.io/download/#redis-downloads
wget https://download.redis.io/redis-stable.tar.gz
Latest Stable
The latest stable release is always available at the fixed https://download.redis.io/redis-stable.tar.gz URL along with its SHA-256 sum.
二、安装文档：
https://redis.io/docs/install/
三、安装过程：
1. 安装相关依赖包，不然编译安装redis的时候，报错
安装gc++
sudo yum install gcc-c++ -y
++ 安装python3++
[test@localhost redis-7.2.4]$ sudo yum install python3 -y
[sudo] password for test:

2. 编译
cd /data/redis-7.2.4/
make
最后编译成功出现如下说明：
CC logreqres.o
LINK redis-server
INSTALL redis-sentinel
CC redis-cli.o
CC redisassert.o
CC cli_common.o
CC cli_commands.o
LINK redis-cli
CC redis-benchmark.o
LINK redis-benchmark
INSTALL redis-check-rdb
INSTALL redis-check-aof
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/data/redis-7.2.4/src'
[test@localhost redis-7.2.4]$
3.安装并指定安装目录
[test@localhost redis-7.2.4]$ mkdir …/redis
[test@localhost redis-7.2.4]$ make PREFIX=/data/redis install
4.修改redis.conf 配置
bind 127.0.0.1 10.10.100.232
daemonize yes
pidfile /data/redis/redis_6379.pid
port 5278
databases 16
maxmemory 512mb
logfile "redis.log"
为了安全起见，防止危险命令 ，编辑配置文件,进行重命名 redis.conf
rename-command FLUSHALL "YKFLUSHALL"
rename-command FLUSHDB "YKFLUSHDB"
rename-command CONFIG "YKCONFIG"
rename-command KEYS "YKKEYS"
rename-command SHUTDOWN "YKSHUTDOWN"
rename-command DEL "YKDEL"
rename-command EVAL "YKEVAL"
设置后需要重启，设置前后比对:
++ 设置前++
127.0.0.1:5278> shutdown
not connected>
++ 设置后++
127.0.0.1:5278> shutdown
(error) ERR unknown command 'shutdown', with args beginning with:
127.0.0.1:5278>
127.0.0.1:5278> ykshutdown
not connected> exit
5.验证客户端连接
[test@localhost conf]$ /data/redis/bin/redis-cli -p 5278
127.0.0.1:5278> auth Ykocredis#2024
OK
127.0.0.1:5278>
6.制作启动脚本
vi /data/script/redis-start
#!/bin/bash
app_home="/data/redis"
cd $app_home
7. 启动 redis
$app_home/bin/redis-server $app_home/conf/redis.conf
四、常见问题
若是未安装python，会出现如下报错
cd src && make install
which: no python3 in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/test/.local/bin:/home/test/bin)
make[1]: Entering directory `/data/redis-7.2.4/src'
CC Makefile.dep
make[1]: Leaving directory `/data/redis-7.2.4/src'
which: no python3 in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/test/.local/bin:/home/test/bin)
make[1]: Entering directory `/data/redis-7.2.4/src'
Hint: It's a good idea to run 'make test' ;)
INSTALL redis-server
INSTALL redis-benchmark
INSTALL redis-cli
make[1]: Leaving directory `/data/redis-7.2.4/src'
