redis-cluster集群6.2.0安装

规划

名称	ip	端口
redis集群6.2.0	172.21.210.49	7001、7002
redis集群6.2.0	172.21.210.50	7001、7002
redis集群6.2.0	172.21.210.51	7001、7002

环境：centos7

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

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

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"

dbfilename dump.rdb
dir /opt/redis/redis7001/data/

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

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

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
