官方安装文档

https://redis.io/docs/getting-started/installation/install-redis-from-source/

1 下载对应版本的redis源码包

redis-6.2.3.tar.gz
链接：https://pan.baidu.com/s/1ep0L4LCsmL4bmRL28ax_zA?pwd=5vd2
提取码：5vd2

2 上传到服务器

上传到usr/local/下

tar -zxvf redis-6.2.3.tar.gz 

3 编译安装redis

cd redis-6.2.3
make
make install

[root@iZ8vbdcrmm49bxv7sirrv3Z redis-6.2.3] make install
cd src && make install
make[1]: Entering directory `/usr/local/redis-6.2.3/src'CC Makefile.dep
make[1]: Leaving directory `/usr/local/redis-6.2.3/src'
make[1]: Entering directory `/usr/local/redis-6.2.3/src'Hint: It's a good idea to run 'make test' ;)INSTALL redis-serverINSTALL redis-benchmarkINSTALL redis-cli
make[1]: Leaving directory `/usr/local/redis-6.2.3/src'

4 编辑redis配置文件

先备份原有文件
mv redis.conf redis.conf.bak

再创建一个新的
vim redis.conf

# 启动端口
port 8391# 密码
requirepass admin# RDB持久化
save 900 1
save 300 10
save 60 10000# 持久化压缩
rdbcompression yes# RDB持久化文件
dbfilename dump.rdb# 开启AOF
appendonly yes# 文件名
appendfilename "appendonly.aof"# 每秒持久化一次（推荐）
appendfsync everysec            

5 按照配置文件启动redis

在/usr/local/redis-6.2.3下执行

[root@shanghai redis-6.2.3]# ./src/redis-server ./redis.conf
19181:C 07 Dec 2022 14:51:47.660 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

6 在不同端口启动多个redis

只需要复制redis-6.2.3文件，然后改变配置文件中的端口，分别启动即可

7 外界无法访问问题解决

redis默认安装只能本机连接，外网无法使用，修改配置文件

1、注释掉bind 允许所有ip连接redis
# bind 0.0.0.0 2、注释redis保护模式
# protected-mode yes3、设置reids密码
requirepass 123456 

重启即可
