Building Apache Solr

General Notes:

When following the steps below, please use a standard permission user unless otherwise specified.
A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Apache Solr binaries are available and can be downloaded from here. To use these binaries, different Java flavors can be installed on mentioned distributions.

Note: Apache Solr (v9.6.0) was verified at the time of creation of these instructions

Step 1: Install Dependencies

export SOURCE_ROOT=/<source_root>/

```
- With Eclipse Adoptium Temurin Runtime
  - Download and install Eclipse Adoptium Temurin Runtime (Java 11, Java 17 or Java 21) from here .

Note: At the time of creation of these build instructions, Apache Solr 9.6.0 was verified with Eclipse Adoptium Temurin Runtime version 11.0.22 (build 11.0.22+7), Eclipse Adoptium Temurin Runtime version 17.0.10 (build 17.0.10+7), Eclipse Adoptium Temurin Runtime version 21.0.2 (build 21.0.2+13).

Step 2 : Set Environment Variables

Set JAVA_HOME and PATH

export JAVA_HOME=<Path to Java>
export PATH=$JAVA_HOME/bin:$PATH

Step 3: Verification

3.1) Start Solr and create a core

Extract Apache Solr binary tar to $SOURCE_ROOT and follow steps given below.

cd $SOURCE_ROOT/<Apache_Solr_binary_folder>/bin
sudo chmod a+x solr
./solr start
./solr create -c sample

3.2) Expected Output

The./solr start command will start the Solr server on port 8983. The ./solr create -c sample command should create a core and output:

Created new core 'sample'

Access the Solr Admin Console at: http://HOST_IP:8983/solr/
