Download the Graylog image from the package site, uncompress it and import it into the OpenStack image store:
$ wget https://packages.graylog2.org/releases/graylog-omnibus/qcow2/graylog-2.2.3-1.qcow2.gz $ gunzip graylog-2.2.3-1.qcow2.gz $ glance image-create --name='graylog' --is-public=true --container-format=bare --disk-format=qcow2 --file graylog-2.2.3-1.qcow2
You should now see an image called graylog in the OpenStack web interface under Images
Launch a new instance of the image, make sure to reserve at least 4GB ram for the instance. After spinning up, login with the username ubuntu and your selected ssh key. Run the reconfigure program in order to setup Graylog and start all services:
$ ssh ubuntu@<vm IP> $ sudo graylog-ctl reconfigure
Open http://<vm ip> in your browser to access the Graylog web interface. Default username and password is admin.
We are shipping the
graylog-ctl tool with the virtual machine appliances to get you started
with a customised setup as quickly as possible. Run these (optional) commands to configure the
most basic settings of Graylog in the appliance:
sudo graylog-ctl set-email-config <smtp server> [--port=<smtp port> --user=<username> --password=<password>] sudo graylog-ctl set-admin-password <password> sudo graylog-ctl set-timezone <zone acronym> sudo graylog-ctl reconfigure
graylog-ctl has much more functionality documented.
We strongly recommend to learn more about it to ensure smooth operation of your virtual appliance.
You can use the Graylog appliances (OVA, Docker, AWS, ...) for small production setups but please consider to harden the security of the box before.
- Set another password for the default ubuntu user
- Disable remote password logins in /etc/ssh/sshd_config and deploy proper ssh keys
- Separate the box network-wise from the outside, otherwise Elasticsearch and MongoDB can be reached by anyone
- add additional RAM to the appliance and raise the java heap!
- add additional HDD to the appliance and extend disk space.
- add the appliance to your monitoring and metric systems.
