环境：centos7
yum -y install gcc
1、软件安装
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
data /opt/redis/redis7001/data log /opt/redis/redis7001/log config /opt/redis/redis7001/config

4、配置文件需要修改项
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
[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）
[root@host-172-21-210-49 bin]# ./redis-cli --cluster create --cluster-replicas 1 172.21.210.49:7001 172.21.210.49:7002 172.21.210.50:7001 172.21.210.50:7002 172.21.210.51:7001 172.21.210.51:7002 >>> Performing hash slots allocation on 6 nodes...

7、查看集群状态
[root@host-172-21-210-49 bin]# ./redis-cli -h 172.21.210.49 -p 7001 -c cluster nodes 185d409bed817b9ce3eb0a37b67c73da015e4dd9 172.21.210.50:7001@17001 master - 0 1615369178943 3 connected 5461-10922 dd04963417efae84e3f34679972138ea13cbfecc 172.21.210.50:7002@17002 slave 6ba72e5deed297988a13aa489a50ab511f57832b 0 1615369176939 1 connected 51c07a2503cb4538cec28914383c5928256edbd4 172.21.210.49:7002@17002 slave 2dfba2c4f639ff02c3ec8b6779536fad529a1b2d 0 1615369177000 5 connected 2dfba2c4f639ff02c3ec8b6779536fad529a1b2d 172.21.210.51:7001@17001 master - 0 1615369177000 5 connected 10923-16383 da882be5c6ac4c75fc02d13040503751c0d69e4a 172.21.210.51:7002@17002 slave 185d409bed817b9ce3eb0a37b67c73da015e4dd9 0 1615369178000 3 connected 6ba72e5deed297988a13aa489a50ab511f57832b 172.21.210.49:7001@17001 myself,master - 0 1615369179000 1 connected 0-5460
8、设置密码
./redis-cli -c -h 172.21.210.49 -p 7001 config set masterauth 123456 config set requirepass 123456 auth 123456 config rewrite
