ln -s /usr/local/lib64/libstdc++.so.6.0.24 /usr/lib64/libstdc++.so.6
rm -f /lib64/libstdc++.so.6
ln -s /usr/local/lib64/libstdc++.so.6.0.24 /lib64/libstdc++.so.6
Install Node.js below
19. cd /home/user1/software
20. wget https://npm.taobao.org/mirrors/node/latest-v8.x/node-v8.11.1.tar.xz
21. tar xvJf ./node-v8.11.1.tar.xz
22. cd node-v8.11.1
23. ./configure
24. make
此时用时很长，耐心等待。。。
25. make install
26. node -v
出现v8.11.1说明安装Node成功。
