For those of you who didn’t know, Apache Solr is an open source enterprise search platform used to easily create search engines which searches websites, files and databases. Its major features include powerful full-text search, faceted search, distributed search, hit highlighting and index replication. But before you proceed, make sure you have already installed Tomcat which is necessary to access Solr from the browser.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation Apache Solr on Ubuntu 14.04.
Step 1. First, Install Java.
Because tomcat and solr are Java based softwares we need the Java environment (As it is advised in the Solr wiki : prefere a full JDK to a simple JRE.)
Add the webupd8team Java PPA repository in your system:
After added the PPA, run commands below one by one to install Java:
Verify installed Java version:
Step 2. Install Apache Solr.
Ubuntu provides 3 Solr packages by default: nsolr-commo, the package that contains the actual Solr code; solr-tomcat, Solr integrated with Tomcat; and solr-jetty, which is just like solr-tomcat but with the Jetty web server. In this article, we will install solr-tomcat, so execute the following command:
Then let’s start the server:
Important: the config & index will be stored at : /usr/share/solr/
Step 3. Install tomcat management utilities.
Once installed, you’ll have to grant some user:
Paste these lines (change username and password as you whish):
Step 4. Accessing Apache Solr.
Apache Solr will be available on HTTP port 8080 by default. Open your favorite browser and navigate to http://yourdomain.com:8080/solr or http://server-ip:8080/solr. If you are using a firewall, please open port 8080 to enable access to the control panel.
