Ceph Calamari Installation (Ubuntu14.04)

1. Overview

The entire deployment architecture of calamari can be simplified to the following illustration, including the client and calamari systems. The calamari system consists of the calamari server and the agents running on the Ceph cluster. The agent keeps sending data to the Calamari server, which stores the data in the database. The client can connect the Calamari server through the HTTP protocol and show the State and information of the Ceph cluster system.

2. Service-Side installation

1) Installation Saltstack

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:saltstack/salt
sudo apt-get Update
sudo apt-get install salt-master=0.17.5+ds-1
sudo apt-get install salt-minion=0.17.5+ds-1

2) Installation Dependency pack

sudo apt-get update && sudo apt-get install-y apache2 \
Libapache2-mod-wsgi Libcairo2 Supervisor Python-cairo Libpq5 PostgreSQL

3) Installation Calamari

sudo dpkg-i calamari-server*.deb calamari-clients*.deb

4 initialization of the service-side

sudo calamari-ctl initialize

Print the following, and note that the login password is entered.
[INFO] Loading configuration.
[INFO] Starting/enabling Salt ...
[INFO] Starting/enabling Postgres ...
[INFO] Initializing database ...
[INFO] Initializing Web Interface ...
[INFO] You are now being prompted for login details for the administrative user account. This are the account you'll use to log into the Web interface once setup is complete.

[INFO] Restarting services ...-more at:http://ceph.com/category/calamari/#sthash. Qutbu0mx.dpuf

When the initialization is complete, the client opens the browser and the address is accessible. However, the Ceph cluster is not configured at this time and prompts for ceph cluster configuration. As shown in the following figure.

3. Agent Installation

1 log in one of the Ceph cluster machines (assuming that the Ceph cluster is Ubuntu), install the monitoring service.

sudo dpkg-i diamond_3.4.67_all.deb

2 Create the default monitoring configuration file

sudo mv/etc/diamond/diamond.conf.example/etc/diamond/diamond.conf

3) Installation of Salt-minion service

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:saltstack/salt
sudo apt-get Update
sudo apt-get install salt-minion=0.17.5+ds-1

4) in /etc/hostsAdd Calamari server Mapping to File
/etc/hosts
...
...
192.168.26.10 Ceph-calamari

5) Modify the Salt-minion configuration file /etc/salt/minion, point master to the Calamari server
/etc/salt/minion

...
Master:ceph-calamari
...
6) Restart Service

sudo service salt-minion restart
sudo service diamond restart

Repeat the above steps on all ceph cluster machines.

After installation, the effect is as follows:

4. Problems that may be encountered

IOError: [Errno] Permission denied: '/var/log/calamari/cthulhu.log '
