others-how to install nodejs/npm on a linux server without internet connection(offline)?

May 17, 2022

1. Purpose

In this post, I would introduce how to install nodejs(or node.js) and npm(nodejs package manager) on a linux server that does not have internet connection.

2. Install node(nodejs or node.js)

Download node

Navigate to nodejs official website to download the node.js install package. Choose the source code package.

3. Configure and Compile(Make) node.js

Now we can extract files from the package:

tar -zxvf node-v16.15.0-linux-x64.tar.xz

Then configure it:

[root@bswen-k8s-app1 node-v16.15.0]# ./configure
Node.js configure: Found Python 3.8.13...
Traceback (most recent call last):
  File "./configure", line 27, in <module>
    import configure
  File "/opt/node-v16.15.0/configure.py", line 14, in <module>
    import bz2
  File "/usr/local/python3/lib/python3.8/bz2.py", line 19, in <module>
    from _bz2 import BZ2Compressor, BZ2Decompressor
ModuleNotFoundError: No module named '_bz2'
[root@bswen-k8s-app1 node-v16.15.0]#

We got error ModuleNotFoundError: No module named '_bz2',so try to install the _bz2 module:

goto here to download libbz2-dev

[root@bswen-k8s-app1 ~]# rpm -ivh bzip2-devel-1.0.6-13.el7.x86_64.rpm
preparing...                          ################################# [100%]

   1:bzip2-devel-1.0.6-13.el7         ################################# [100%]

rebuild python3 again:

./configure --prefix=/usr/local/python3  --enable-optimizations
make && make install
make altinstall

Now try to configure node again:

[root@bswen-k8s-app1 node-v16.15.0]# ./configure
Node.js configure: Found Python 3.8.13...
WARNING: C++ compiler (CXX=g++, 4.8.5) too old, need g++ 8.3.0 or clang++ 8.0.0
WARNING: warnings were emitted in the configure phase
INFO: configure completed successfully
[root@bswen-k8s-app1 node-v16.15.0]# make && make install

At last, we should create symbolic link to make the binary executable from command line:

[root@bswen-k8s-app1 node-v16.15.0-linux-x64]# ln -s /opt/node-v16.15.0-linux-x64/bin/node /usr/local/bin/node
[root@bswen-k8s-app1 node-v16.15.0-linux-x64]# ln -s /opt/node-v16.15.0-linux-x64/bin/npm /usr/local/bin/npm

Now we have installed the nodejs/npm offline, we can test it as follows: check installation:

[root@bswen-k8s-app1 node-v16.15.0-linux-x64]# node --version
v16.15.0
[root@bswen-k8s-app1 node-v16.15.0-linux-x64]# npm --version
8.5.5

4. Summary

In this post, I demonstrated how to install nodejs(or node.js) and npm(nodejs package manager) on a linux server that does not have internet connection. That’s it, thanks for your reading.
