    For new installations we encourage you to use pm2 or nodemon

    $ npm install pm2@latest -g
# or
$ yarn global add pm2

     

     

    npm install -g nodemon

     

    nodemon [your node app]

       DEPRECATION WARNING
        Node.js 12.x is no longer actively supported!
        You will not receive security or critical stability updates for this version.
        You should migrate to a supported version of Node.js as soon as possible.
        Use the installation script that corresponds to the version of Node.js you
        wish to install. e.g.

    Step 1 – Add Node.js Yum Repository

    First of all, You need to enable the node.js yum repository in your system provided by the Node.js official website. You also need development tools to build native add-ons to be installed on your system.

    For Stable Release:-

    yum install -y gcc-c++ make
    curl -sL https://rpm.nodesource.com/setup_16.x | sudo -E bash -

    Step 2 – Install Node.js on CentOS

    After adding a yum repository to your system let’s install the Node.js package. NPM will also be installed with node.js. This command will also install many other dependent packages on your system.

    yum install nodejs

    Step 3 – Check Node.js and NPM Version

    After installing node.js verify and check the installed version. You can find more details about current version on node.js official website.

    node -v v18.7.0

    Also, check the version of npm.

    npm -v7.13.0

    You have successfully installed Node.js on your CentOS 7 system. You may try a demo HTTP server as given below.

    Step 4 – Create Demo Web Server (Optional)

    This is an optional step. If you want to test your node.js install. Let’s create a web server with the “Welcome Node.js” text. Create a file demo_server.js

    cd /var/www/html
nano demo_server.jsand add the following content
    var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Welcome Node.js');
}).listen(3001, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3001/');

    Save your file and close.

    Now start the web server using the command.

    node --inspect demo_server.jsDebugger listening on ws://127.0.0.1:9229/9e0c7b4a-2ffe-48df-a4b0-b4635dcd9359
For help, see: https://nodejs.org/en/docs/inspector
Server running at http://127.0.0.1:3001/

    The web server has been started on port 3001. Now access http://127.0.0.1:3001/ URL in browser.

    Installing forever

    Forever can be used in two ways: with the forever CLI tool and with forever-monitor. The forever-monitor tool can be used to run an application with forever using code. We will see forever-monitor in action later in this article.

    To use forever, we need to install it globally:

    npm i -g forever

    Running a script with forever

    Running a script with forever is simple. First, use the following command:

    forever start app.js

    Note that app.js is the name of the script. We can also add a -a flag with the above command. This flag will ensure that log files get appended to the default log file located at forever’s default log file location. There are many other flags available that can be appended to the forever command.

    We can also run multiple scripts at once by separating the script names with spaces. Here is an example:

    forever start app.js index.js

    When you start the processes using the above commands, you’ll receive some warnings and information about the file that it is processing.

    After you start the script, you can list all the running processes with the list command, like so:

    forever list

    forever --version
    v4.0.3
    (node:13935) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
    (Use `node --trace-warnings ...` to show where the warning was created)

    Installing NVM on CentOS 7

    NVM provides a simple bash script for the installation on Linux systems. Open a terminal on your system or connect a remote system using SSH.

    Make sure your system have curl installed.

    yum install curl -y

     

    Then execute the installer script as following command:

    curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash   


    => Appending nvm source string to /root/.bashrc
    => Appending bash_completion source string to /root/.bashrc
    => You currently have modules installed globally with `npm`. These will no
    => longer be linked to the active version of Node when you install a new node
    => with `nvm`; and they may (depending on how you construct your `$PATH`)
    => override the binaries of modules installed with `nvm`:

    /usr/lib
    ├── corepack@0.15.1
    ├── forever@4.0.3
    └── yarn@1.22.19
    => If you wish to uninstall them at a later point (or re-install them under your
    => `nvm` Nodes), you can remove them from the system Node as follows:

         $ nvm use system
         $ npm uninstall -g a_module

    => Close and reopen your terminal to start using nvm or run the following to use it now:

    export NVM_DIR="$HOME/.nvm"
    [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
    [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

     

    https://bobbyhadz.com/blog/node-glibc-not-found-required-by-node

    node: version `GLIBC_2.28` not found (required by node)

    ldd --version

     

     

    There are 2 common ways to solve the error:

    1. Install an older, more widely supported version of Node.js (16.X).
    2. Upgrade your Linux operating system to a newer version.

     

     

    To find the default Node version set for the current user, type:

    nvm run default --version

    You can run a Node script with the desired version of node.js using the below command:

    nvm exec 12.18.3 server.js

     

     

     

    1. cd /tmp
    2. wget https://nodejs.org/dist/v10.15.3/node-v10.15.3-linux-x64.tar.xz
    3. tar xf node-v10.15.3-linux-x64.tar.xz
    4.  mkdir /usr/local/lib/nodejs
    5. mv /tmp/node-v10.15.3-linux-x64/* /usr/local/lib/nodejs
    6. nano ~/.profile
      # Nodejs
      VERSION=v10.15.0
      DISTRO=linux-x64
      export PATH=/usr/local/lib/nodejs/bin:node
    7. ln -s /usr/local/lib/nodejs/bin/node /usr/bin/node
    8. ln -s /usr/local/lib/nodejs/bin/npm /usr/bin/npm
    9. ln -s /usr/local/lib/nodejs/bin/npx /usr/bin/npx
    10. node -v
    11. npm version
    12. npx -v

     

    Installing NVM (Node Version Manager)

    1. To install nvm, execute the command below.

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

    The installer script will be running and adding a new configuration to the '~/.bashrc' file.

    Install Node Using the Node Version Manager

    Another way of installing Node.js that is particularly flexible is through NVM, the Node version manager. This piece of software allows you to install and maintain many different independent versions of Node.js, and their associated Node packages, at the same time.

    To install NVM on your CentOS 7 machine, visit the project's GitHub page. Copy the

    curl or wget

    command from the README file that displays on the main page. This will point you towards the most recent version of the installation script.
     

    Before piping the command through to bash, it is always a good idea to audit the script to make sure it isn't doing anything you don't agree with. You can do that by removing the

    | bash segment at the end of the curl command:
    curl https://raw.githubusercontent.com/creationix/nvm/v0.13.1/install.sh

    Take a look and make sure you are comfortable with the changes it is making. When you are satisfied, run the command again with | bash appended at the end. The URL you use will change depending on the latest version of NVM, but as of right now, the script can be downloaded and executed by typing:

    

    curl https://raw.githubusercontent.com/creationix/nvm/v0.13.1/install.sh | bash
    This will install the nvm script to your user account. To use it, you must first source your
    .bash_profile:
    

    

    source ~/.bash_profile
    Now, you can ask NVM which versions of Node it knows about:
    

    

    nvm list-remote
    v0.1.14
         v0.1.15
         v0.1.16
