How to automatically stop Solr service on system shutdown?

To automatically stop the Solr service on system shutdown, you can create a systemd service unit file that will define the actions to be taken when the system shuts down. Here's how you can do it:

1. Create a new systemd service unit file for Solr:

1

sudo nano /etc/systemd/system/solr.service

1. Add the following configuration to the service unit file:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

[Unit]
Description=Apache Solr
After=network.target

[Service]
Type=forking
ExecStart=/path/to/solr/bin/solr start
ExecStop=/path/to/solr/bin/solr stop
User=solr
Group=solr

[Install]
WantedBy=multi-user.target

Replace /path/to/solr with the actual path to your Solr installation directory.

1. Enable the Solr service to start on boot:

1

sudo systemctl enable solr

1. Reload the systemd manager configuration:

1

sudo systemctl daemon-reload

Now, the Solr service should automatically stop when the system shuts down or reboots.

How to stop Solr during peak traffic hours?

Stopping Solr during peak traffic hours can be quite disruptive to your users and can result in downtime for your search functionality. However, if it is absolutely necessary to stop Solr during peak traffic hours, here are some steps you can take to minimize the impact on your users:

1. Schedule the maintenance window: Prioritize the maintenance window during off-peak hours to minimize the impact on users. Ideally, schedule the stoppage during times when traffic is at its lowest, such as overnight or early in the morning.
2. Notify users in advance: Inform your users about the planned maintenance in advance through email, notifications on your website, or social media. Let them know the estimated downtime and when they can expect the service to be restored.
3. Redirect traffic to a backup server: If possible, set up a backup Solr server or use a load balancer to direct search traffic to a secondary server while the primary server is undergoing maintenance. This can help minimize the impact on users and ensure continuity of service.
4. Monitor the situation: Keep a close eye on server performance during the maintenance period to ensure that everything is operating smoothly. Be prepared to quickly address any issues that may arise to minimize downtime.
5. Communicate updates: Keep your users informed about any changes or updates during the maintenance period. Provide regular updates on the progress of the maintenance and when the service is expected to be restored.

By following these steps and carefully planning the stoppage of Solr during peak traffic hours, you can minimize the impact on your users and ensure a smooth transition back to normal service once maintenance is complete.
