The homologated version of Apache Solr for CITSmart is 6.4.2. The package can be downloaded from the website itself at the URL [https://archive.apache.org/dist/lucene/solr/](https://archive.apache.org/dist/lucene/solr/). In the specific case for CITSmart you'll also need to download the configuration files (Knowledge Base Confs) that can be downloaded from the partner relationship area in the Installation Components.

## Installing SOLR

Download the package to the server /tmp

```shell
[root@server /tmp]# https://archive.apache.org/dist/lucene/solr/6.4.2/solr-6.4.2.tgz
```

Extract the install script with the command below:

```shell
[root@server /tmp]# tar -xvf solr-6.4.2.tgz solr-6.4.2/bin/install_solr_service.sh --strip-components=2
solr-6.4.2/bin/install_solr_service.sh
```

Run the install script as follows:

```shell
[root@server /tmp]# ./install_solr_service.sh solr-6.4.2.tgz
id: solr: no such user
Creating new user: solr

Extracting solr-6.4.2.tgz to /opt

[root@server /tmp]#

```

Import CITSmart settings into the SOLR. To do this, send via scp to the server the base\_knowledge\_configs.zip file that was downloaded from the partner area. Assuming the file is in `/tmp`, and you have the unzip, run the command below:

```shell
[root@server /tmp]# unzip base_conhecimento_configs.zip -d /opt/solr-6.4.2/
```

Faça login com usupário do SOLR:

```shell
[root@server /tmp]# su - solr -s /bin/bash
```

E execute o comando abaixo:

```shell
[root@server /tmp]# /opt/solr/bin/solr create -c base_conhecimento -d /opt/solr/base_conhecimento_configs -s 2 -rf 2

Copying configuration to new core instance directory:
/var/solr/data/base_conhecimento

Creating new core 'base_conhecimento' using command:
http://localhost:8983/solr/admin/cores?action=CREATE&name=base_conhecimento&instanceDir=base_conhecimento

{
  "responseHeader":{
    "status":0,
    "QTime":1606},
  "core":"base_conhecimento"}


[root@server /tmp]#

```

After the message above, SOLR is configured.
