GCC and other environments have been installed, and the ways of recompiling after clearing compilation information and deleting decompressed files and redecompressing compilation have been tried without improvement. Later, it was found that it was related to the version of GCC

//Check gcc Version
gcc -v

Centos7 default version for 4.8.5

and redis6.0 + need GCC version 5.3 and above, so upgrade GCC can be

//Upgrade gcc to V9 or high
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

You also need to execute the command

//change the current gcc version to 9
scl enable devtoolset-9 bash
//or change permanetly
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
