In the last recipe, we compiled the packages required for Calamari, which includes the calamari-server, calamari-client, and diamond. If you have not compiled these packages by yourself, you can download them from my GitHub repository at https://github.com/ksingh7/ceph-calamari-packages/tree/master/CentOS-el7.
In this demonstration, we will be configuring ceph-node1 as the Calamari master server, as well as the salt-minion node, ceph-node2, and ceph-node3 as salt-minion nodes only. At the time of writing this recipe, Calamari did not support salt version 2015, so I have intentionally used salt version 2014.
Let's now begin the installation of the Calamari server:
- On
ceph-node1, install the dependency packages required by salt and the Calamari server:# yum install -y python-crypto PyYAML systemd-python yum-utils m2crypto pciutils python-msgpack systemd-python python-zmq - By default, CentOS7 will install salt's latest version, so in order to install salt version 2014, set up the salt repo:
# wget https://copr.fedoraproject.org/coprs/saltstack/salt/repo/epel-7/saltstack-salt-epel-7.repo -O /etc/yum.repos.d/saltstack-salt-epel-7.repo - Install the salt master and salt minion version 2014.7.5:
# yum --disablerepo="*" --enablerepo="salt*" install -y salt-master-2014.7.5-1.el7.centos - Since this is a test setup, we will stop and disable the firewall:
# systemctl stop firewalld # systemctl disable firewalld
- Next, install the Calamari server packages. Make sure this does not update the salt version to 2015:
# yum install https://github.com/ksingh7/ceph-calamari-packages/raw/master/CentOS-el7/calamari-server-1.3.0.1-49_g828960a.el7.centos.x86_64.rpm - Next, we will install the Calamari server package that installs the dashboard component of Calamari:
# yum install -y https://github.com/ksingh7/ceph-calamari-packages/raw/master/CentOS-el7/calamari-clients-1.2.2-32_g931ee58.el7.centos.x86_64.rpm - Enable and start the
salt-masterservice:# systemctl enable salt-master # systemctl restart salt-master
- At this point, our Calamari server is installed, and we should now configure it by running the following command:
# calamari-ctl initialize
- At the time of writing this section, Calamari had a known bug (updating the connected minion), which will end up with an error during the Calamari initialize step. You can skip this step if your
calamari-ctlinitialize command went fine. To fix this bug, edit the/opt/calamari/venv/lib/python2.7/site-packages/calamari_cthulhu-0.1-py2.7.egg/cthulhu/calamari_ctl.pyfile and comment out line 255 that saysupdate_connected_minions():
- Next, visit the Calamari dashboard by pointing your browser at
http://192.168.1.101/dashboard/, and provide the username asrootand the password as what you set in the last step.
- Once you are logged into the Calamari dashboard, you will see a screen similar to the following; as this is a fresh installation of Calamari, we need to add Ceph nodes to it, and it has been described in the following recipe:
