环境：centos7

软件下载： https://download.redis.io/releases/

yum -y install gcc

1、软件安装

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

使用以下命令下载，提取和编译Redis： $ wget https://download.redis.io/releases/redis-6.2.1.tar.gz $ tar xzf redis-6.2.1.tar.gz $ cd redis-6.2.1 $ make 注意：【Redis】编译错误zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory  解决：make MALLOC=libc src 目录 中现在提供了已编译的二进制文件 。使用以下命令运行Redis： $ src/redis-server 您可以使用内置客户端与Redis进行交互： $ src/redis-cli redis> set foo bar OK redis> get foo "bar"

2、配置文件路径

?

4、配置文件需要修改项

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

bind 172.21.210.49 protected-mode no port 7001 daemonize yes pidfile /opt/redis/redis7001/config/redis.pid logfile "/opt/redis/redis7001/log/redis.log" save 3600 1 save 300 100 save 60 10000 dbfilename dump.rdb dir /opt/redis/redis7001/data/ cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 15000

5、启动redis脚本

?

1 2 3 4 5 6 7 8 9 10

[root@host]# cat start.sh #!/bin/bash dir=$(cd `dirname $0`;pwd) cd $dir bin/redis-server config/redis.conf [root@host]# chmod u+x start.sh   配置其他节点，拷贝文件修改config，然后都启动 /opt/redis/redis7001/start.sh /opt/redis/redis7002/start.sh

6、创建集群（低版本用的pury脚本，高版本直接redis-cli）
