Install MEAN Stack on CentOS 7

Install MEAN Stack on CentOS 7

MEAN is a free and open-source JavaScript software stack. MEAN stack is named using the first letter of its four components MongoDB, Express.js, AngularJS and Node.js. Because all four components of MEAN stack support JavaScript therefore MEAN stack is used for both server-side and client-side execution environments for building dynamic websites and web applications using JavaScript.

In this article, we are installing MEAN stack on CentOS 7 server. Here, we are not emphasizing on the developments and deployments of JavaScript based web applications on MEAN stack. Therefore, if you want to explore MEAN stack in depth, then you should read MEAN Web Development by Packt Publishing.

 

This Article Provides:

     

    Environment Specification:

    We have provisioned a CentOS 7 virtual machine with following specifications.

    • CPU – 3.4 Ghz (Single Core)
    • Memory – 2 GB
    • Storage – 20 GB
    • Operating System – CentOS 7.6
    • Hostname – nodejs-01.example.com
    • IP Address – 192.168.116.190 /24

     

    Installing MEAN Stack Prerequisite Packages:

    Connect with nodejs-01.example.com using ssh as root user.

    These packages are required by various components of MEAN stack; therefore, we are installing them in one go using yum command.

    Installing MongoDB 4 on CentOS 7:

    MongoDB is not available in standard yum repositories. Therefore, we have to install MongoDB official yum repository on our CentOS 7 server and then we will be able to install MongoDB database.

    Create a yum repository file in /etc/yum.repos.d directory.

    [root@nodejs-01 ~]# vi /etc/yum.repos.d/mongodb.repo

    and add following configurations therein.

    [mongodb-org-4.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

    Build cache for MongoDB yum repository.

    [root@nodejs-01 ~]# yum makecache fast Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp3.isra.edu.pk * extras: ftp3.isra.edu.pk * updates: ftp3.isra.edu.pk base | 3.6 kB 00:00 extras | 3.4 kB 00:00 mongodb-org-4.0 | 2.5 kB 00:00 updates | 3.4 kB 00:00 mongodb-org-4.0/7/primary_db | 53 kB 00:00 Metadata Cache Created

    Install MongoDB 4 on our CentOS 7 server using yum command.

    MongoDB database service ‘mongod.service’ is automatically enabled by the installer. We are only required to start MongoDB service once.

    [root@nodejs-01 ~]# systemctl start mongod.service

    MongoDB 4 has been installed on our CentOS 7 server.

     

    Installing Node.js 10 on CentOS 7:

    Node.js is not available in standard yum repositories. Therefore, we have to install Node.js official yum repository then we will be able to install Node.js.

    Node.js provides a binary installer that installs Node.js yum repository. Therefore, download and execute that binary file as follows.

    [root@nodejs-01 ~]# curl -sL https://rpm.nodesource.com/setup_10.x | sudo -E bash - ## Installing the NodeSource Node.js 10.x repo... ## Inspecting system... + rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release + uname -m ## Confirming "el7-x86_64" is supported... + curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_10.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm' ## Downloading release setup RPM... + mktemp + curl -sL -o '/tmp/tmp.8FUOG96Pkq' 'https://rpm.nodesource.com/pub_10.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm' ## Installing release setup RPM... + rpm -i --nosignature --force '/tmp/tmp.8FUOG96Pkq' ## Cleaning up... + rm -f '/tmp/tmp.8FUOG96Pkq' ## Checking for existing installations... + rpm -qa 'node|npm' | grep -v nodesource ## Run `sudo yum install -y nodejs` to install Node.js 10.x and npm. ## You may also need development tools to build native addons: sudo yum install gcc-c++ make ## To install the Yarn package manager, run: curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo sudo yum install yarn

    Now, we have installed Node.js yum repository. Note down the commands to install Yarn package manager on CentOS 7. We will use these commands to install Yarn package manager later in this article.

    Install Node.js 10 on our CentOS 7 server using yum command.

    [root@nodejs-01 ~]# yum install -y nodejs Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp3.isra.edu.pk * extras: ftp3.isra.edu.pk * updates: ftp3.isra.edu.pk Resolving Dependencies --> Running transaction check ---> Package nodejs.x86_64 2:10.16.0-1nodesource will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: nodejs x86_64 2:10.16.0-1nodesource nodesource 19 M Transaction Summary ================================================================================ Install 1 Package Total download size: 19 M Installed size: 56 M Downloading packages: nodejs-10.16.0-1nodesource.x86_64.rpm | 19 MB 00:43 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : 2:nodejs-10.16.0-1nodesource.x86_64 1/1 Verifying : 2:nodejs-10.16.0-1nodesource.x86_64 1/1 Installed: nodejs.x86_64 2:10.16.0-1nodesource Complete!

    Verify version of Node.js and relevant libraries.

    Node.js 10 has been installed on our CentOS 7 server.

    npm, the Node.js package manager, is also installed with Node.js. We can use npm to install rest of the components of MEAN stack.

     

    Installing Yarn Package Manager on CentOS 7:

    Yarn is a package manager for front-end applications. It is a replacement of Bower package manager, that was used in previous versions of MEAN stack.

    Install Yarn official yum repository as follows.

    [root@nodejs-01 ~]# curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo [yarn] name=Yarn Repository baseurl=https://dl.yarnpkg.com/rpm/ enabled=1 gpgcheck=1 gpgkey=https://dl.yarnpkg.com/rpm/pubkey.gpg

    Install Yarn using yum command.

    Installing Gulp Task Scheduler on CentOS 7:

    Gulp is a JavaScript task scheduler. Gulp is required by Node.js and we can install it using npm command.

    [root@nodejs-01 ~]# npm install -g gulp /usr/bin/gulp -> /usr/lib/node_modules/gulp/bin/gulp.js npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules/gulp/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"}) + gulp@4.0.2 added 314 packages from 217 contributors in 67.397s

     

    Installing MEAN Stack on CentOS 7:

    Download latest version of MEAN stack from GitHub using git command.

    [root@nodejs-01 ~]# cd /tmp [root@nodejs-01 tmp]# git clone https://github.com/linnovate/mean Cloning into 'mean'... remote: Enumerating objects: 16743, done. remote: Total 16743 (delta 0), reused 0 (delta 0), pack-reused 16743 Receiving objects: 100% (16743/16743), 8.04 MiB | 415.00 KiB/s, done. Resolving deltas: 100% (9154/9154), done.

    Testing MEAN Stack on CentOS 7:

    To test our MEAN stack configurations, we are running a sample application as follows.

    [root@nodejs-01 mean]# cd /tmp/mean [root@nodejs-01 mean]# cp .env.example .env [root@nodejs-01 mean]# npm start > mean@2.0.2 start /tmp/mean > concurrently -c "yellow.bold,green.bold" -n "SERVER,BUILD" "nodemon server" "ng build --watch" [SERVER] [nodemon] 1.19.1 [SERVER] [nodemon] to restart at any time, enter `rs` [SERVER] [nodemon] watching: *.* [SERVER] [nodemon] starting `node server` [SERVER] ../../dist/ [SERVER] (node:7803) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version.

      1. Thanks for appreciation.
        I honor your request but this blog is about system administration of Linux servers.

        If you want to learn MEAN stack then please read the recommended book in the above article.
