When properly configured it will alert you when something on your server goes wrong and then notify you again once the problem has been resolved. In this tutorial, we will show you how to install and configure the latest Nagios Core version on a CentOS 7 VPS.<\/p>\n<p><!--more--><\/p>\n<h2>Step 1: Connect to your server<\/h2>\n<p>Connect to your server via SSH as user root, use the following command:<\/p>\n<pre>ssh root@IP_ADDRESS -p PORT_NUMBER<\/pre>\n<p>and replace <code>IP_ADDRESS<\/code> and <code>PORT_NUMBER<\/code> with your actual server IP address and SSH port number.<\/p>\n<p>Once logged in, make sure that your server is up-to-date by running the following command:<\/p>\n<pre>yum update<\/pre>\n<h2>Step 2: Install LAMP<\/h2>\n<p>For Nagios Core to work on your server you will also need to set up a LAMP or any other web hosting stack. If you already have working web hosting stack installed on your server you can skip this and go to the next step of this tutorial.<\/p>\n<p>To install a LAMP stack with Apache, MariaDB and PHP 7 on your CentOS server, run the following command:<\/p>\n<pre>yum install httpd mariadb-server php php-mysql<\/pre>\n<p>When the MariaDB installation is complete, you can also run the following command to secure your MariaDB installation:<\/p>\n<pre>mysql_secure_installation<\/pre>\n<p>You will also need to enable MariaDB and Apache to start on boot with:<\/p>\n<pre>systemctl enable httpd.service\r\nsystemctl enable mariadb.service<\/pre>\n<h2>Step 3: Install the required packages<\/h2>\n<p>The following packages are also be required by the Nagios Core software. You can install them with the following command:<\/p>\n<pre>yum install gcc glibc glibc-common wget gd gd-devel perl postfix<\/pre>\n<h2>Step 4: Download and Install Nagios Core<\/h2>\n<p>Let&#8217;s download the latest stable version of the Nagios Core.<\/p>\n<p>First, navigate to the <code>tmp<\/code> directory on your server with:<\/p>\n<pre>cd \/tmp<\/pre>\n<p>and run the following command to download the tar archive file:<\/p>\n<pre>wget -O nagioscore.tar.gz https:\/\/github.com\/NagiosEnterprises\/nagioscore\/archive\/nagios-4.4.2.tar.gz<\/pre>\n<p>Once the download is complete, execute the following command to extract the archive file:<\/p>\n<pre>tar xzf nagioscore.tar.gz<\/pre>\n<p>Once the archive is extracted, move to the <code>nagioscore-nagios-4.4.2<\/code> directory:<\/p>\n<pre>cd \/tmp\/nagioscore-nagios-4.4.2<\/pre>\n<p>and run the following command in order to configure the installer and prepare the Nagios Core source code for the compilation process:<\/p>\n<pre>.\/configure<\/pre>\n<p>After the configuration is completed, you can now compile Nagios Core by execution the following command:<\/p>\n<pre>make all<\/pre>\n<p>You also need to run the following commands to create the <code>nagios<\/code> user and group and add <code>apache<\/code> to the <code>nagios<\/code> group:<\/p>\n<pre>make install-groups-users\r\nusermod -a -G nagios apache<\/pre>\n<p>Now, you can finally run the following command in order to install Nagios Core:<\/p>\n<pre>make install<\/pre>\n<p>To, install the initialization script which can be used to manage your Nagios service, run the following command:<\/p>\n<pre>make install-daemoninit<\/pre>\n<p>Next, run the following command to install the Nagios sample configuration files:<\/p>\n<pre>make install-config<\/pre>\n<p>Run the following command to install and configure the external command file to make Nagios Core to work from the command line:<\/p>\n<pre>make install-commandmode<\/pre>\n<p>The following command will install the Apache web server configuration files:<\/p>\n<pre>make install-webconf<\/pre>\n<p>After all the installations are complete, restart your apache service with:<\/p>\n<pre>systemctl restart httpd<\/pre>\n<h2>Step 5: Create nagiosadmin User Account<\/h2>\n<p>To be able to log into Nagios, you will need to create an Apache user account.<\/p>\n<p>You need to run the following command to create a new user account called <code>nagiosadmin<\/code> and assign a password to it:<\/p>\n<pre>htpasswd -c \/usr\/local\/nagios\/etc\/htpasswd.users nagiosadmin<\/pre>\n<p>With this step, the main Nagios Core installation is now complete. However, for Nagios Core to operate properly you will also need to install the Nagios Plugins as explained in the next step.<\/p>\n<h2>Step 6: Install Nagios Plugins<\/h2>\n<p>Before you download and install the Nagios plugins, you need to make sure that the following packages are installed on your CentOS 7 server:<\/p>\n<pre>yum install gcc glibc glibc-common make gettext automake autoconf wget openssl-devel net-snmp net-snmp-utils epel-release perl-Net-SNMP<\/pre>\n<p>To download and extract the latest version of the Nagios Plugins to the <code>tmp<\/code> directory on your server, run the following commands:<\/p>\n<pre>cd \/tmp\r\nwget --no-check-certificate -O nagios-plugins.tar.gz https:\/\/github.com\/nagios-plugins\/nagios-plugins\/archive\/release-2.2.1.tar.gz\r\ntar zxf nagios-plugins.tar.gz<\/pre>\n<p>Once the Nagios Plugins archive is extracted, run the following commands to compile and install the Nagios Plugins on your server:<\/p>\n<pre>cd \/tmp\/nagios-plugins-release-2.2.1\/\r\n.\/tools\/setup\r\n.\/configure\r\nmake\r\nmake install<\/pre>\n<h2>Step 7: Accessing Nagios Core<\/h2>\n<p>After you have successfully installed Nagios Core and the Nagios Plugins your CentOS 7 system, you can use the following command to start the Nagios service:<\/p>\n<pre>systemctl start nagios<\/pre>\n<p>To access Nagios Core, open your browser and navigate to <code>http:\/\/YOUR-IP-ADDRESS\/nagios<\/code> and log in using the\u00a0<code>nagiosadmin<\/code>\u00a0user account which you have created in one of the previous steps in this tutorial.<\/p>\n<p>After you have successfully logged in, you will be presented with the Nagios Core home screen as shown in the image below:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-664\" src=\"https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/09\/install-nagios-on-centos-7.jpg\" alt=\"install nagios on centos 7\" width=\"500\" height=\"339\" srcset=\"https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/09\/install-nagios-on-centos-7.jpg 500w, https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/09\/install-nagios-on-centos-7-300x203.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>Congratulations!
