开始以为是jemalloc版本问题，手动下载了jemalloc版本并且安装，但是仍然报错。又尝试修改内存分配器为glibc的 MALLOC=libc，结果同样报错。通过搜索后发现是gcc版本太低，高版本的编译要求！

安装9以上的gcc

yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile

安装后最好永久写入环境变量，防止运行时也需要，也不影响默认环境
