Today we are going to Install i-doit tool on our Ubuntu 18.04. It has various features due to which we prefer it in our IT system. i-doit is Professional IT documentaion & CMDB tool that provides the way to manage the entire IT system.

With the help of this great tool you can easily create a detailed overview of the entire IT-infrastructure for all kind of assets.

System Requirements

• 2 vCPUs
• 2 GB RAM
• 10 GB free disc space

As we will Install it on our dedicated Virtual Machine, LAMP Stack is required.

• Apache Web Server 2.4
• MariaDB 10.x or MySQL 5.6 or later
• PHP 5.6(deprecated), 7.x
• PHP extensions: bcmath, ctype, curl, fileinfo, gd, imagick, json, ldap, mbstring, memcached, mysqli, mysqlnd, pgsql, session, soap, xml, zip

Now, move toward the Installation of i-doit on our Ubuntu system

Step 1: Install Apache & PHP

Run the following command to Install Apache & required PHP extensions.

sudo apt -y install apache2 libapache2-mod-php
sudo apt -y install php-{bcmath,cli,common,curl,gd,json,ldap,mbstring,mysql,opcache,pgsql,soap,xml,zip,imagick,memcached}
sudo apt -y install memcached unzip moreutils

Create new php configuration file for i-doit

sudo tee /etc/php/7.2/mods-available/i-doit.ini<<EOF
   allow_url_fopen = Yes
   file_uploads = On
   magic_quotes_gpc = Off
   max_execution_time = 300
   max_file_uploads = 42
   max_input_time = 60
   max_input_vars = 10000
   memory_limit = 256M
   post_max_size = 128M
   register_argc_argv = On
   register_globals = Off
   short_open_tag = On
   upload_max_filesize = 128M
   display_errors = Off
   display_startup_errors = Off
   error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
   log_errors = On
   default_charset = "UTF-8"
   default_socket_timeout = 60
   date.timezone = Africa/Nairobi
   session.gc_maxlifetime = 604800
   session.cookie_lifetime = 0
   mysqli.default_socket = /var/run/mysqld/mysqld.sock
   EOF 

session.gc_maxlifetime should be the same or greater than the Session Timeout in the System settings of i-doit.

Then activate the required PHP modules & restart Apache web server.

sudo phpenmod i-doit
 sudo phpenmod memcached
 sudo systemctl restart apache2.service

Step 2: Install MariaDB Server

Install MariaDB on your Ubuntu 18.04

After Installing MariaDB & configuring it login to it, & run the given command.

SET GLOBAL innodb_fast_shutdown = 0;
 UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root';
 FLUSH PRIVILEGES;

Tune your server for Optimal Perfromance

sudo nano /etc/mysql/mariadb.conf.d/99-i-doit.cnf

Then add the below content:

[mysqld]
 This is the number 1 setting to look at for any performance optimization
 It is where the data and indexes are cached: having it as large as possible will
 ensure MySQL uses memory and not disks for most read operations.
 #
 Typical values are 1G (1-2GB RAM), 5-6G (8GB RAM), 20-25G (32GB RAM), 100-120G (128GB RAM).
 innodb_buffer_pool_size = 1G
 Use multiple instances if you have innodb_buffer_pool_size > 10G, 1 every 4GB
 innodb_buffer_pool_instances = 1
 Redo log file size, the higher the better.
 MySQL/MariaDB writes two of these log files in a default installation.
 innodb_log_file_size = 512M
 innodb_sort_buffer_size = 64M
 sort_buffer_size = 262144 # default
 join_buffer_size = 262144 # default
 max_allowed_packet = 128M
 max_heap_table_size = 32M
 query_cache_min_res_unit = 4096
 query_cache_type = 1
 query_cache_limit = 5M
 query_cache_size = 80M
 tmp_table_size = 32M
 max_connections = 200
 innodb_file_per_table = 1
 Disable this (= 0) if you have only one to two CPU cores, change it to 4 for a quad core.
 innodb_thread_concurrency = 0
 Disable this (= 0) if you have slow harddisks
 innodb_flush_log_at_trx_commit = 1
 innodb_flush_method = O_DIRECT
 innodb_lru_scan_depth = 2048
 table_definition_cache = 1024
 table_open_cache = 2048
 Only if your have MySQL 5.6 or higher, do not use with MariaDB!
 table_open_cache_instances = 4
 innodb_stats_on_metadata = 0
 sql-mode = ""

When finished, restart mariadb

sudo systemctl restart mysql

Step 3: Download i-doit

Download & extract the open source version of i-doit

export LATEST="1.13.2"
wget https://sourceforge.net/projects/i-doit/files/i-doit/$LATEST/idoit-open-$LATEST.zip
sudo unzip idoit-open-$LATEST.zip -d /var/www/html/i-doit

Set permissions for the created directory to apache user

cd /var/www/html/i-doit
 sudo chown www-data:www-data -R .
 sudo find . -type d -name * -exec chmod 775 {} \;
 sudo find . -type f -exec chmod 664 {} \;
 sudo chmod 774 controller .sh setup/.sh

Then create Apache configuration file for i-doit.

sudo tee /etc/apache2/sites-available/i-doit.conf<
         ServerAdmin admin@example.com
     DirectoryIndex index.php     DocumentRoot /var/www/html/     <Directory /var/www/html/>             AllowOverride All             Require all granted     </Directory>     LogLevel warn     ErrorLog ${APACHE_LOG_DIR}/error.log     CustomLog ${APACHE_LOG_DIR}/access.log combined
 
 EOF

Enable site & rewrite module.

sudo chown www-data:www-data -R /var/www/html/
sudo chmod 755 /var/log/apache2
sudo chmod 664 /var/log/apache2/*
sudo a2ensite i-doit
sudo a2enmod rewrite
sudo systemctl restart apache2.service

Step 4: Run i-doit Setup

Launch the i-doit by opening http://idoit.example.com/i-doit/.

All system checks should show a pass.

Do the all steps as shown in screenshots below

• Connection Settings
• Host: localhost or 127.0.0.1
• Port: default port of MySQL/MariaDB, so 3306
• Username: User name of the database system user, usually root
• Password: Password of the user
• MySQL user settings
• Username: User name of the i-doit databases owner, usually idoit
• Password: Pass of the user
• Database settings
• System Database Name: Name of the system DB, usually idoit_system
• Mandator Database Name: Name of the database for the first tenant, usually idoit_data
• Mandator title: name of the organization that is focused on
• Start value for object/configuration item IDs: Normally 1

Then finalize the configuration check & move to next step

After it login to the i-doit by providing your credentials.

You now have Installed i-doit on Ubuntu system.

Further Steps

• Download & Install a License
• Set up backup
• Set up Cronjobs
