     167== LibreNMS ==
     168
     169=== Installing LibreNMS ===
     170
     171    These instructions assume you are the root user. If you are not, prepend ''sudo'' to the shell commands (the ones that aren't at ''mysql>'' prompts) or temporarily invoke root privileges.
     172
     173 
     174==== Create database ====
     175
     176'''NOTE''': These instructions are based on the official LibreNMS installation notes and have been tested on a fresh install of Ubuntu 16.0.
     177
     178We will assume that the database is running on the same machine as your network management server (this is the most common initial deployment scenario).
     179
     180First install mysql and configure:
     181{{{
     182# apt-get update (Already done)
     183# apt-get install mysql-server mysql-client
     184}}}
     185You will be asked to enter a password for the MySQL root user. Be absolutely sure that you remember what you choose here. You will use this later.
     186{{{
     187# mysql -uroot -p
     188}}}
     189Input the MySQL root password (the one you chose in the previous step) to enter the MySQL command-line interface where you will get a mysql> prompt.
     190
     191Create the database:
     192{{{
     193CREATE DATABASE librenms;
     194GRANT ALL PRIVILEGES ON librenms.*
     195TO 'librenms'@'localhost'
     196IDENTIFIED BY '<Your Password>'
     197;
     198FLUSH PRIVILEGES;
     199exit
     200}}}
     201PLEASE NOTE
     202
     203Here we are using <your Password> as the password for LibreNMS to access MySQL. Please replace <your Password> with, Please do not forget the password as you will need it in the future
     204
     205==== Install LibreNMS ====
     206
     207The NMS is the host is where the web server and SNMP poller run.
     208
     209Install the required software:
     210{{{
     211apt-get install libapache2-mod-php7.0 php7.0-cli php7.0-mysql php7.0-gd php7.0-snmp php-pear php7.0-curl snmp graphviz php7.0-mcrypt php7.0-json apache2 fping imagemagick whois mtr-tiny nmap python-mysqldb snmpd php-net-ipv4 php-net-ipv6 rrdtool git
     212}}}
     213
     214The packages listed above are an all-inclusive list of packages that were necessary on a clean install of Ubuntu 16.0
     215
     216==== snmp ====
     217
     218You need to configure snmpd appropriately if you have not already done so. We will do a minimal snmp configuration on our server -- '''please DON'T''' do this if you've already configured SNMP earlier!
     219{{{
     220# mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.orig
     221# vi /etc/snmp/snmpd.conf
     222}}}
     223and, add the following line to the empty file:
     224{{{
     225rocommunity NetManage 127.0.0.1
     226}}}
     227And, now restart the snmp service so that the changes become active.
     228{{{
     229# service snmpd restart
     230}}}
     231You can verify that snmp now responds to you locally by typing:
     232{{{
     233# snmpstatus -v2c -c NetManage 127.0.0.1 sysStatus
     234}}}
     235
     236==== php ====
     237
     238In both '''/etc/php/7.0/apache2/php.ini''' and '''/etc/php/7.0/cli/php.ini''', ensure '''date.timezone''' is set to your preferred time zone.
     239
     240See <http://php.net/manual/en/timezones.php> or files under ''/usr/share/zoneinfo'' for a list of supported timezones. For this workshop we are all going to use the same timezone.
     241
     242In the two archives noted above find the line that reads:
     243{{{
     244;date.timezone =
     245}}}
     246and change it to:
     247{{{
     248date.timezone = Asia/Colombo
     249}}}
     250Save and exit from the files.
     251
     252 
     253==== Adding the LibreNMS user ====
     254
     255We need to create a LibreNMS system user, librenms
     256
     257# useradd librenms -d /opt/librenms -M -r
     258# usermod -a -G librenms www-data
     259
     260 
     261==== Cloning the LibreNMS source code with git ====
     262
     263LibreNMS is installed using git. If you're not familiar with git, check out the git book or the tips at git ready. The initial install from github.com is called a ''git clone''; subsequent updates are done through ''git pull''.
     264
     265The initial clone can take quite a while (nearly 3 minutes on a 10Mbps connection is typical) as the size of the software repository is 220+ MB in size.
     266
     267Run the following:
     268{{{
     269# cd /opt
     270# git clone https://github.com/librenms/librenms.git librenms
     271}}}
     272At this point, you should have a ''librenms'' directory, with the most recent revision checked out.
     273
     274
     275==== Web Interface ====
     276
     277To prepare the web interface (and adding devices shortly), you'll need to create and change the ownership of a directory as well as create an Apache Virtul Host definition.
     278
     279First, create and chown the ''rrd'' directory and create the ''logs'' directory:
     280{{{
     281# cd /opt/librenms
     282# mkdir rrd logs
     283# chown -R librenms:librenms /opt/librenms
     284# chmod 775 rrd
     285# chown www-data /opt/librenms
     286}}}
     287Next, create '''/etc/apache2/sites-available/librenms.conf''':
     288{{{
     289 # vi /etc/apache2/sites-available/librenms.conf
     290}}}
     291Add the following lines:
     292{{{
     293<VirtualHost *:80>
     294  DocumentRoot /opt/librenms/html/
     295  ServerName librenms."your domain".ws.ac.lk
     296  CustomLog /opt/librenms/logs/access_log combined
     297  ErrorLog /opt/librenms/logs/error_log
     298  AllowEncodedSlashes NoDecode
     299  <Directory "/opt/librenms/html/">
     300    Require all granted
     301    AllowOverride All
     302    Options FollowSymLinks MultiViews
     303  </Directory>
     304</VirtualHost>
     305}}}
     306
     307Now enable the Virtual Host, but wait to restart Apache
     308{{{
     309# a2ensite librenms.conf
     310# a2enmod rewrite
     311# service apache2 restart
     312}}}
     313
