2、错误原因

gcc版本问题，新版本的。redis6.0以上

# 查看gcc版本
gcc -v

3、解决办法

#升级到 5.3及以上版本
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

scl enable devtoolset-9 bash

#注意：scl命令启用只是临时的，推出xshell或者重启就会恢复到原来的gcc版本。
#如果要长期生效的话，执行如下：
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
