EnterpriseApps/ApacheSolr

1. Ставим java-1.8.0-openjdk

# apt-get install java-1.8.0-openjdk

2.Качаем бинарный релиз

https://solr.apache.org/downloads.html

3. распаковываем его в /opt

tar zxf /home/petr/Загрузки/solr-9.4.0.tgz -C /opt

4. Создаем системного пользователя solr

adduser --system -U -m --home-dir /home/solr solr

5. Назначаем права на каталоги Solr

chown -R root: /opt/solr-9.4.0
chmod -R 0755 /opt/solr-9.4.0/bin

6. Создаем каталог с настройками и копируем в него файл с параметрами программы

mkdir /etc/default
chown root: /etc/default
chmod 0755 /etc/default
cp "/opt/solr-9.4.0/bin/solr.in.sh" "/etc/default/solr.in.sh"

7. правим файл /etc/default/solr.in.sh

Добавляем в него следкющие строки:

SOLR_PID_DIR="/home/solr"
SOLR_HOME="/home/solr/data"
LOG4J_PROPS="/home/solr/log4j2.xml"
SOLR_LOGS_DIR="/home/solr/logs"
SOLR_PORT="8983"

8. Создаем каталоги и назначаем права

mkdir -p "/home/solr/data"
mkdir -p "/home/solr/logs"
chown -R solr: /opt/solr-9.4.0/

9. Копируем файл с настройками, назначаем права и создаем символьную ссылку

cp /opt/solr-9.4.0/server/resources/log4j2.xml /home/solr/log4j2.xml
chown -R solr: /home/solr
ln -s '/opt/solr-9.4.0' /opt/solr

10. Создаем файл

/etc/init.d/solr

# Example of a very simple *nix init script that delegates commands to the bin/solr script
# Typical usage is to do:
#
#   cp bin/init.d/solr /etc/init.d/solr
#   chmod 755 /etc/init.d/solr
#   chown root:root /etc/init.d/solr
#   update-rc.d solr defaults
#   update-rc.d solr enable

# Where you extracted the Solr distribution bundle

  exit 1

11. Создаем файлы служб

chmod +x /etc/init.d/solr

---

/etc/systemd/system/solr.service

---

[Unit]
SourcePath=/etc/init.d/solr
Description=Apache Solr as a Service
Before=multi-user.target
Before=graphical.target
After=remote-fs.target

[Service]
Type=forking

12. Включаем службу

systemctl enable --now solr
systemctl status solr
