--环境
centos7.5
1.官网下载安装包 redis-5.0.7.tar.gz （最新的稳定版本）
2.上传至服务器安装目录/home，解压安装包
cp redis-5.0.7.tar.gz /home/
tar -xvf redis-5.0.7.tar.gz
3.安装依赖包gcc
yum install gcc
4.编译安装
cd redis-5.0.7
make && make install
5.执行初始化脚本
cd redis-5.0.7/utils/
./install_server.sh
6.编辑修改配置文件
vim /etc/redis/6379.conf
找到第70行的bind 127.0.0.1
改为：bind 0.0.0.0
7.重启redis
/etc/init.d/redis_6379 stop
/etc/init.d/redis_6379 start
--配置集群测试（单机）,集群模式至少需要六个redis节点，六个配置文件不能在同一目录
进入redis安装目录
[[email protected] init.d]# cd /home/redis-5.0.7
创建config目录
[[email protected] redis-5.0.7]# mkdir config
[[email protected] redis-5.0.7]# cd config/
在config目录下创建主从节点配置文件，并启动，启动命令需要在子文件夹下。因为nodes.conf文件是生成在当前目录的。
