解决办法：

# 查看gcc版本是否在5.3以上，centos7.6默认安装4.8.5
gcc -v
# 升级gcc到5.3及以上,如下：
升级到gcc 9.3：
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。
如果要长期使用gcc 9.3的话：

echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
这样退出shell重新打开就是新版的gcc了
以下其他版本同理，修改devtoolset版本号即可。

其他命令

# 编译出错时，清出编译生成的文件
make distclean
# 编译安装到指定目录下
make PREFIX=/usr/local/redis install 
# 卸载
make uninstall
