linux（centos）环境下安装nodejs

地址替换为新版本地址wget http://nodejs.org/dist/v0.6.1/node-v0.6.1.tar.gz

tar zxvf node-v0.6.1.tar.gz 
cd node-v0.6.1 
./configure 
上面几行命令是通过wget命令下载最新版本的代码，并解压之。./configure命令将会检查环境是否符合Nodejs的编译需要。

期间遇到gcc版本过低的问题，执行以下

wget http://ftp.gnu.org/gnu/gcc/gcc-6.1.0/gcc-6.1.0.tar.gz
tar -zvxf gcc-6.1.0.tar.gz --directory=/usr/local/
cd /usr/local/gcc-6.1.0
./contrib/download_prerequisites  
mkdir build && cd build  
 ../configure -enable-checking=release -enable-languages=c,c++ -disable-multilib  
make && make install

执行ok，重新执行

./configure

make 
make install 

测试安装是否成功
node -v
