解决方案

针对问题一

升级glibc到glibc-2.17版本，由于我只是在预发环境升级的，所以运维同学在升级的时候可以采用自己的方法进行升级，我这边只是记录我的升级步骤。

参考链接：https://blog.csdn.net/wyl9527/article/details/78256066，之前网上有推荐说采用软链接方式，但是没成功，最后还是采用覆盖的方式

直接覆盖了旧的glibc

tar –zxvf glibc-2.17.tar.gz

cd glibc-2.17

mkdir build

cd build

../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin

make –j4

make install

安装后查看是否符合要求

针对问题二/三

升级gcc到gcc-6.1.0，参考链接https://blog.csdn.net/zr1076311296/article/details/51334538。

升级完以后拷贝最新的libstdc++.so

cp /usr/local/lib64/libstdc++.so.6.0.22 /usr/lib64/

ln -s/usr/lib64/libstdc++.so.6.0.22 /usr/lib64/libstdc++.so.6

修改软链接（备份旧gcc版本，软链新gcc版本）

mv /usr/bin/gcc /usr/bin/gcc4.4.7

mv /usr/bin/g++ /usr/bin/g++4.4.7

mv /usr/bin/cc /usr/bin/cc4.4.7

mv /usr/bin/c++ /usr/bin/c++4.4.7

ln -s /usr/local/bin/gcc /usr/bin/gcc

ln -s /usr/local/bin/g++ /usr/bin/g++

ln -s /usr/local/bin/cc /usr/bin/cc

ln -s /usr/local/bin/c++ /usr/bin/c++

安装后查看是否符合要求
