Additionally, replace \u2018root\u2019 with the username of the admin account if necessary.<\/p>\r\n\r\n\r\n\r\n<p>Before starting, you have to make sure that all CentOS packages installed on the server are up to date. You can do this by running the following commands:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf update -y<\/pre>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\" id=\"h-step-2-install-required-packages\"><span class=\"ez-toc-section\" id=\"Step-2-Install-Required-Packages\"><\/span>Step 2: Install Required Packages<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p>First, you will need to install some packages required to install Rocket.Chat in your system.<\/p>\r\n\r\n\r\n\r\n<p>First, install EPEL repo with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf install epel-release -y<\/pre>\r\n\r\n\r\n\r\n<p>After installing, EPEL repo, install Nginx web server and development tools with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf install nginx curl GraphicsMagick gcc-c++ -y\r\ndnf groupinstall 'Development Tools'<\/pre>\r\n\r\n\r\n\r\n<p>Once all the packages are installed, start the Nginx service and enable it to start at system reboot:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">systemctl start nginx\r\nsystemctl enable nginx<\/pre>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\" id=\"h-step-3-install-node-js\"><span class=\"ez-toc-section\" id=\"Step-3-Install-Nodejs\"><\/span>Step 3: Install Node.js<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p>Next, you will need to install Node.js in your system. By default, the latest version of Node.js is not available in the CentOS 8 default repository. So you will need to enable the Node.js module in your system. You can enable the Node.js version 12 module with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf module enable nodejs:12<\/pre>\r\n\r\n\r\n\r\n<p>Next, install the Node.js with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf install nodejs -y<\/pre>\r\n\r\n\r\n\r\n<p>After installing Node.js, verify the installed version of Node.js with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">node --version<\/pre>\r\n\r\n\r\n\r\n<p>You should get the following output:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">v12.18.4\r\n<\/pre>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\" id=\"h-step-4-install-and-configure-mongodb\"><span class=\"ez-toc-section\" id=\"Step-4-Install-and-Configure-MongoDB\"><\/span>Step 4: Install and Configure MongoDB<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n\r\n\r\n\r\n<p>Rocket.Chat uses MongoDB as a database backend. So you will need to install it in your system.<\/p>\r\n\r\n\r\n\r\n<p>First, create a MongoDB repo with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">nano \/etc\/yum.repos.d\/mongodb-org.repo<\/pre>\r\n\r\n\r\n\r\n<p>Add the following lines:<\/p>\r\n\r\n\r\n\r\n<p>[mongodb-org-3.6]<\/p>\r\n\r\n\r\n\r\n<p>name=MongoDB Repository baseurl=https:\/\/repo.mongodb.org\/yum\/redhat\/$releasever\/mongodb-org\/3.6\/x86_64\/ gpgcheck=1 enabled=1 gpgkey=https:\/\/www.mongodb.org\/static\/pgp\/server-3.6.asc<\/p>\r\n\r\n\r\n\r\n<p>Save and close the file then install the MongoDB server with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">dnf install mongodb-org -y<\/pre>\r\n\r\n\r\n\r\n<p>Once installed, start the MongoDB service and enable it to start at system reboot with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">systemctl start mongod\r\nsystemctl enable mongod<\/pre>\r\n\r\n\r\n\r\n<p>Next, you will need to define replica set in MongoDB. You can define it with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">nano \/etc\/mongod.conf<\/pre>\r\n\r\n\r\n\r\n<p>Add the following lines:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">replication:\r\n  replSetName: \"myreplica01\"\r\n<\/pre>\r\n\r\n\r\n\r\n<p>Save and close the file then restart the MongoDB service to apply the changes:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">systemctl restart mongod<\/pre>\r\n\r\n\r\n\r\n<p>Next, login to MongoDB shell and initiate the replica set with the following command:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">mongo\r\n\r\n&gt; rs.initiate()<\/pre>\r\n\r\n\r\n\r\n<p>You should get the following output:<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">{\r\n    \"info2\" : \"no configuration specified.
