Icinga is written in C++ and PHP and stores the information in the <a href=\"https:\/\/linuxhostsupport.com\/blog\/how-to-import-an-sql-file-into-mysql-database\/\" title=\"\">MySQL database<\/a>. It offers many features, such as modern user interface database connectors for MySQL, PostgreSQL, Oracle, REST API, etc. In this blog post, we will install Icinga 2 with the <a href=\"https:\/\/www.rosehosting.com\/lamp-hosting\/\" title=\"\">LAMP stack<\/a>.<\/p>\n\n\n\n<p>Installing Icinga 2 with LAMP stack is a process that may take up to 30 minutes. Let&#8217;s get started!<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">Prerequisites<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A server with Ubuntu 22.04 as OS<\/li>\n\n\n\n<li>User privileges: root or non-root user with sudo privileges<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1. Update the System<\/h2>\n\n\n\n<p>Before we start to install the software, we need to update the system packages to the latest versions available.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get update -y &amp;&amp; sudo apt-get upgrade -y<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2. Install LAMP stack<\/h2>\n\n\n\n<p>First of the LAMP stack is the Apache Web server. To install it execute the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt install apache2 -y<\/pre>\n\n\n\n<p>Once installed, start and enable the service.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl enable apache2 &amp;&amp; sudo systemctl start apache2<\/pre>\n\n\n\n<p>Check if the service is up and running:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl status apache2<\/pre>\n\n\n\n<p>You should receive the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">root@host:~# sudo systemctl status apache2\n\u25cf apache2.service - The Apache HTTP Server\n     Loaded: loaded (\/lib\/systemd\/system\/apache2.service; enabled; vendor preset: enabled)\n     Active: active (running) since Sat 2023-04-22 18:00:43 CDT; 17min ago\n       Docs: https:\/\/httpd.apache.org\/docs\/2.4\/\n   Main PID: 792 (apache2)\n      Tasks: 7 (limit: 4571)\n     Memory: 22.5M\n        CPU: 246ms\n     CGroup: \/system.slice\/apache2.service\n<\/pre>\n\n\n\n<p>Next is PHP, along with its extensions. To install the PHP8.1 along with extensions, execute the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get install php8.1 php8.1-cli php8.1-common php8.1-imap php8.1-redis php8.1-snmp php8.1-xml php8.1-zip php8.1-mbstring php8.1-curl libapache2-mod-php\n<\/pre>\n\n\n\n<p>The last of the LAMP stack is the MariaDB database server. To install it execute the command below.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt install mariadb-server -y<\/pre>\n\n\n\n<p>Start and enable the mariadb.service with the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl start mariadb &amp;&amp; sudo systemctl enable mariadb<\/pre>\n\n\n\n<p>Check the status of the mariadb.service<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl status mariadb<\/pre>\n\n\n\n<p>You should receive the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">root@host:~# sudo systemctl status mariadb\n\u25cf mariadb.service - MariaDB 10.6.12 database server\n     Loaded: loaded (\/lib\/systemd\/system\/mariadb.service; enabled; vendor preset: enabled)\n     Active: active (running) since Sat 2023-04-22 18:19:53 CDT; 9s ago\n       Docs: man:mariadbd(8)\n             https:\/\/mariadb.com\/kb\/en\/library\/systemd\/\n   Main PID: 5829 (mariadbd)\n     Status: \"Taking your SQL requests now...\"\n      Tasks: 16 (limit: 4571)\n     Memory: 61.4M\n        CPU: 514ms\n     CGroup: \/system.slice\/mariadb.service\n             \u2514\u25005829 \/usr\/sbin\/mariadbd\n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3. Install Icinga 2<\/h2>\n\n\n\n<p>First, we will add the GPG key, and will create a repository:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">wget -O - https:\/\/packages.icinga.com\/icinga.key | gpg --dearmor -o \/usr\/share\/keyrings\/icinga-archive-keyring.gpg\n\n. \/etc\/os-release; if [ ! -z ${UBUNTU_CODENAME+x} ]; then DIST=\"${UBUNTU_CODENAME}\"; else DIST=\"$(lsb_release -c| awk '{print $2}')\"; fi; \\\n echo \"deb [signed-by=\/usr\/share\/keyrings\/icinga-archive-keyring.gpg] https:\/\/packages.icinga.com\/ubuntu icinga-${DIST} main\" > \\\n \/etc\/apt\/sources.list.d\/${DIST}-icinga.list\n echo \"deb-src [signed-by=\/usr\/share\/keyrings\/icinga-archive-keyring.gpg] https:\/\/packages.icinga.com\/ubuntu icinga-${DIST} main\" >> \\\n \/etc\/apt\/sources.list.d\/${DIST}-icinga.list\n\n<\/pre>\n\n\n\n<p>Update the system and install Icinga2<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt update -y\n\nsudo apt install icinga2 -y<\/pre>\n\n\n\n<p>After installation, start and enable the icinga2 service.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl start icinga2 &amp;&amp; sudo systemctl enable icinga2<\/pre>\n\n\n\n<p>Check the status of Icinga 2:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl status icinga2<\/pre>\n\n\n\n<p>You should get the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">root@host:~# sudo systemctl status icinga2\n\u25cf icinga2.service - Icinga host\/service\/network monitoring system\n     Loaded: loaded (\/lib\/systemd\/system\/icinga2.service; enabled; vendor preset: enabled)\n    Drop-In: \/etc\/systemd\/system\/icinga2.service.d\n             \u2514\u2500limits.conf\n     Active: active (running) since Sat 2023-04-22 19:06:11 CDT; 4min 35s ago\n   Main PID: 11632 (icinga2)\n     Status: \"Startup finished.\"\n      Tasks: 16\n     Memory: 14.3M\n        CPU: 435ms\n     CGroup: \/system.slice\/icinga2.service\n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4. Install the Icinga2 IDO Module<\/h2>\n\n\n\n<p>To install the Icinga2 IDO module, execute the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt install icinga2-ido-mysql -y<\/pre>\n\n\n\n<p>While installing, choose <b>Yes<\/b> on both windows. It is about Icinga2 using MySQL.<\/p>\n\n\n\n<p>After this, we need to create an <b>icinga2-ido-mysql<\/b> database with the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">CREATE DATABASE icinga_ido_db;\nGRANT ALL ON icinga_ido_db.* TO 'icinga_ido_db'@'localhost' IDENTIFIED BY 'YourStrongPasswordHere';\nFLUSH PRIVILEGES;\nEXIT;\n<\/pre>\n\n\n\n<p>Once the database is created, import the <b>Icinga2 IDO<\/b> schema with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo mysql -u root -p icinga_ido_db &lt; \/usr\/share\/icinga2-ido-mysql\/schema\/mysql.sql<\/pre>\n\n\n\n<p>Once the schema is imported, the next is to enable the Icinga2 IDO module:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">nano \/etc\/icinga2\/features-available\/ido-mysql.conf<\/pre>\n\n\n\n<p>Paste the following lines of code:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">\/**\n * The db_ido_mysql library implements IDO functionality\n * for MySQL.\n *\/\n\nlibrary \"db_ido_mysql\"\n\nobject IdoMysqlConnection \"ido-mysql\" {\n  user = \"icinga_ido_db\",\n  password = \"YourStrongPasswordHere\",\n  host = \"localhost\",\n  database = \"icinga_ido_db\"\n}<\/pre>\n\n\n\n<p>Save the file, close it and enable the Icinga2-ido-mysql with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo icinga2 feature enable ido-mysql<\/pre>\n\n\n\n<p>After this restart the Icinga2 service:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl restart icinga2<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 5. Install and Setup IcingaWeb2<\/h2>\n\n\n\n<p>To install Icinga Web execute the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt install icingaweb2 icingacli -y<\/pre>\n\n\n\n<p>Next is to create a second database for the Icinga web:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">CREATE DATABASE icingaweb2;\nGRANT ALL ON icingaweb2.* TO 'icingaweb2'@'localhost' IDENTIFIED BY 'YourStrongPasswordHere';\nFLUSH PRIVILEGES;\nEXIT;\n<\/pre>\n\n\n\n<p>Next, we need to create an Icinga token:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">root@host:~# sudo icingacli setup token create\nThe newly generated setup token is: dd3a1a8b218be0db\n<\/pre>\n\n\n\n<p>That was all with installing Icinga via the command line. The last step is about finishing the Icinga installation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 6. Finish Icinga Installation<\/h2>\n\n\n\n<p>To finish the Icinga installation, you need to access it at <b>http:\/\/YourServerIPaddress\/icingaweb2\/setup<\/b>.<\/p>\n\n\n<div
