環境：centos7
軟體下載下傳： https://download.redis.io/releases/
yum -y install gcc
1、軟體安裝
使用以下指令下載下傳，提取和編譯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】編譯錯誤zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory
解決：make MALLOC=libc
src 目錄 中現在提供了已編譯的二進制檔案 。使用以下指令運作Redis：
$ src/redis-server
您可以使用内置用戶端與Redis進行互動：
$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"
2、配置檔案路徑
data /opt/redis/redis7001/data
log /opt/redis/redis7001/log
config /opt/redis/redis7001/config
3、配置檔案詳情

5、啟動redis腳本
[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
配置其他節點，拷貝檔案修改config，然後都啟動
/opt/redis/redis7001/start.sh
/opt/redis/redis7002/start.sh
6、建立叢集（低版本用的pury腳本，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、檢視叢集狀态
[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、設定密碼
./redis-cli -c -h 172.21.210.49 -p 7001
config set masterauth 123456
config set requirepass 123456
auth 123456
config rewrite
做一個決定，并不難，難的是付諸行動，并且堅持到底。
