问题原因
CentOS 7的gcc版本为4.8.5，Redis 6.0.5最低需要gcc4.9，因此需要升级gcc版本
from redis 6.0.5, building redis from source code needs C11 support.The version of gcc in CentOS 7 is 4.8.5, but C11 was introduced in 4.9.
解决办法
1、手动编译gcc大于4.9的版本
2、安装 devtoolset-9(使用高版本gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC))编译安装Redis 6.0.5
vi /etc/yum.repos.d/CentOS-SCLo-scl.repo
[centos-sclo-sclo]
name=CentOS-7 - SCLo sclo
baseurl=http://mirror.centos.org/centos/7/sclo/$basearch/rh/
#mirrorlist=http://mirrorlist.centos.org?arch=$basearch&release=7&repo=sclo-sclo
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo
yum install centos-release-scl
yum install devtoolset-9 -y
scl enable devtoolset-9 bash #激活gcc版本，使其生效
临时使用高版本gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC) (推荐使用这个方法)
