--環境
centos7.5
1.官網下載安裝包 redis-5.0.7.tar.gz （最新的穩定版本）
2.上傳至服務器安裝目錄/home，解壓安裝包
cp redis-5.0.7.tar.gz /home/
tar -xvf redis-5.0.7.tar.gz
3.安裝依賴包gcc
yum install gcc
4.編譯安裝
cd redis-5.0.7
make && make install
5.執行初始化腳本
cd redis-5.0.7/utils/
./install_server.sh
6.編輯修改配置文件
vim /etc/redis/6379.conf
找到第70行的bind 127.0.0.1
改爲：bind 0.0.0.0
7.重啓redis
/etc/init.d/redis_6379 stop
/etc/init.d/redis_6379 start
--配置集羣測試（單機）,集羣模式至少需要六個redis節點，六個配置文件不能在同一目錄
進入redis安裝目錄
[root@k8s init.d]# cd /home/redis-5.0.7
創建config目錄
[root@k8s redis-5.0.7]# mkdir config
[root@k8s redis-5.0.7]# cd config/
在config目錄下創建主從節點配置文件，並啓動，啓動命令需要在子文件夾下。因爲nodes.conf文件是生成在當前目錄的。
