Redis v6.0.6 集群cluster模式布署
官网下载redis redis-6.0.6.tar.gz 版本。
环境信息：
| 192.168.199.140(centos 7.5) 7000、7001端口 192.168.199.141(centos 7.5) 7002、7003端口 192.168.199.142(centos 7.5) 7004、7005端口 |
安装编译依赖工具：
yum install -y gcc gcc-c++ jemalloc centos-release-scl devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils （此命令执行2次）
scl enable devtoolset-9 bash
进行编译安装：
make PREFIX=/usr/local/redis install
创建配置目录：
mkdir -p /usr/local/redis/{data,etc,log}
修改各个节点配置文件（更改IP及绑定端口）：

启动各节点redis：
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7000.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7001.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7002.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7003.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7004.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/7005.conf
创建redis集群：
| /usr/local/redis/bin/redis-cli --cluster create \ 192.168.199.140:7000 192.168.199.140:7001 \ 192.168.199.141:7002 192.168.199.141:7003 \ 192.168.199.142:7004 192.168.199.142:7005 \ --cluster-replicas 1 |
连接到集群查看集群信息：
/usr/local/redis/bin/redis-cli -h 192.168.199.140 -p 7000 -c
集群布署完成。
