Linux Centos7安装node环境

1、下载node
Node.js 中文网  
https://nodejs.cn/download/


2、解压
tar -xvf ****.tar.xz

3、配置环境变量
vim /etc/profile
文件最后增加
export PATH=$PATH:你的目录/bin
source /etc/profile  让环境变量配置生效

4、配置淘宝镜像
npm config set registry https://registry.npmmirror.com
查看镜像
npm config get registry


5、centos7服务器安装node之后，只要使用npm或者node，均会出现以下问题
npm -v
node: /lib64/libm.so.6: version `GLIBC_2.27' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.25' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by node)
node: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by node)
node: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by node)
node: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by node)


原因
查看系统内安装的glibc版本
然后再根据分析可得知 新版的nodev18开始都需要GLIBC_2.27支持，可是目前系统内却没有那么高的版本
通过如下命令查看glibc版本
strings /lib64/libc.so.6 |grep GLIBC_


解决办法(更新glibc)
wget http://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
tar xf glibc-2.28.tar.gz 
cd glibc-2.28/ && mkdir build  && cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin


可能出现的错误
configure: error: 
*** These critical programs are missing or too old: make bison compiler
*** Check the INSTALL file for required versions.

解决办法：升级gcc与make
# 升级GCC(默认为4 升级为8)</span>
yum install -y centos-release-scl
yum install -y devtoolset-8-gcc*
mv /usr/bin/gcc /usr/bin/gcc-4.8.5
ln -s /opt/rh/devtoolset-8/root/bin/gcc /usr/bin/gcc
mv /usr/bin/g++ /usr/bin/g++-4.8.5
ln -s /opt/rh/devtoolset-8/root/bin/g++ /usr/bin/g++

# 升级 make(默认为3 升级为4)
wget http://ftp.gnu.org/gnu/make/make-4.3.tar.gz
tar -xzvf make-4.3.tar.gz && cd make-4.3/
./configure  --prefix=/usr/local/make
make && make install
cd /usr/bin/ && mv make make.bak
ln -sv /usr/local/make/bin/make /usr/bin/make

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

依旧报错：bison太老旧
configure: error: 
*** These critical programs are missing or too old: bison
*** Check the INSTALL file for required versions.

解决办法：安装bison
yum install bison

再重新执行 ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
没有问题继续执行
make && make install

验证是否正确
npm -version

若提示如下问题
npm -version
node: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by node)
node: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by node)
node: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by node)

查看动态库CXXABI
strings /usr/lib64/libstdc++.so.6 | grep CXXABI
没有1.3.9需要更新libstdc++.so.6.0.26

#更新lib libstdc++.so.6.0.26
wget https://cdn.frostbelt.cn/software/libstdc%2B%2B.so.6.0.26
#替换系统中的/usr/lib64
cp libstdc++.so.6.0.26 /usr/lib64/
cd /usr/lib64/
ln -snf ./libstdc++.so.6.0.26 libstdc++.so.6

完毕了再设置node的淘宝镜像吧
