Redis-6.0.6版本高可用集群搭建

2020年发布的Redis6.0 是Redis自发布以来最大的升级，提供了多线程支持， ACLs细粒度的权限管理，SSL加密，客户端缓存，集群代理等多项重大更新

公司采购了XXX系统，我决定用目前最高版本的Redis-6.0.6搭建高可用集群，废话不说，直接上步骤

cat /etc/redhat-release

CentOS Linux release 7.6.1810 (Core)

gcc -v

gcc version 4.8.5 20150623

操作系统自带的GCC版本太低，报错make[1]: *** [server.o] Error 1，先升级GCC：

yum -y install centos-release-scl

yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

scl enable devtoolset-9 bash

以上为临时启用，如果要长期使用gcc 9.1的话：

echo “source /opt/rh/devtoolset-9/enable” >>/etc/profile

cd redis-6.0.6/

make PREFIX=/usr/local/redis install

[OK] All nodes agree about slots configuration.
