Installing Bamboo Data Center

These instructions are applicable for installing Bamboo Data Center on your own hardware. 

This guide covers installing for the first time, with no existing data, or migrating your Bamboo Server to a Data Center instance.

Install Bamboo Data Center on a single node

If your organization doesn't need high availability or disaster recovery capabilities right now, you can install Bamboo Data Center without setting up a cluster.

Deploying Data Center on a single node will be the same as deploying a Server installation, just with a different license. Head to  Bamboo installation guide to learn about all the ways in which you can install Bamboo. 

Install Bamboo Data Center in a cluster

If your organization requires continuous uptime and disaster recovery, you'll want to run Bamboo Data Center in a cluster. 

Before you begin

Bamboo Data Center supports only 1 active node and unlimited list of cold-standby nodes which started on-demand if active node fails to run.

Provision the shared database and filesystem nodes

Before you install the first Bamboo application node, you need to provision the shared database and shared filesystem to use with Bamboo Data Center. 

1. Download Bamboo 

To download Bamboo for your operating system, go to  download page.

 2. Create the installation directory

  1. Extract the downloaded file to an install location.

    The path to the extracted directory is referred to as the <Bamboo installation directory> in these instructions.

3. Provision your shared database

Set up your shared database server. 

Ensure your database is configured to allow enough concurrent connections.

See Connecting Bamboo Server to an external database for more information, and note that clustered databases are not supported.

4. Provision your shared file system

You’ll need to create a remote directory that is readable and writable by all nodes in the cluster. There are multiple ways to do this, but the simplest is to use an NFS share.

On your file server, ensure that NFS is configured with enough server processes. For example, some versions of Red Hat Enterprise Linux and CentOS have a default of 8 server processes. If you use either distribution, you may need to edit your /etc/sysconfig/nfs file, increase the value of RPCNFSDCOUNT, and restart the nfs service.

For the file server and cluster nodes, avoid kernel and NFS version combinations that are unstable or have known NFS bugs. We recommend avoiding Linux kernel versions 3.2 to 3.8.

5. Create the local and shared home directories

Bamboo node should have access to 2 folders it uses for files storage: local and shared.
The shared folder is shared between all cluster nodes and used to keep artifacts and other build results. The local home is used to keep node-specific files. The local home should not be accessible by other nodes.

Specify your Bamboo home directories before you run Bamboo for the first time.

Create your Bamboo home directories (without spaces in the name).

You should not create your Bamboo home directory inside the Bamboo installation directory — they should be entirely separate locations. If you do put the home directory in the Bamboo installation directory,    it will be overwritten, and lost, when Bamboo is upgraded. 

6. Configure file share mount

On each cluster node, mount the shared home directory as ${BAMBOO_HOME}/shared . Note that only the ${BAMBOO_HOME}/shared directory should be shared between cluster nodes.  All other directories, including ${BAMBOO_HOME} should be node-local (that is, private to each node).

You can configure a custom location for you home shared folder. Also, when using multiple nodes, you must define a path to a shared home  location. See Configuring shared home location.

Show me an example...

Suppose your Bamboo home directory is /var/atlassian/application-data/bamboo, and your shared home directory is available as an NFS export called  bamboo-san:/bamboo-shared . To configure the mount on each cluster node:

  1. Add the following line to /etc/fstab on each cluster node.
    /etc/fstab

    bamboo-san:/bamboo-shared /var/atlassian/application-data/bamboo/shared nfs rw,nfsvers=3,lookupcache=pos,noatime,intr,rsize=32768,wsize=32768,_netdev 0 0
  2. Mount the share on each node:

    mkdir -p /var/atlassian/application-data/bamboo/shared
    sudo mount -a

7. Synchronize system clocks

Ensure all your cluster nodes have synchronized clocks and identical timezone configuration. Here are some examples for how to do this:

For RedHat Enterprise Linux or CentOS:
sudo yum install ntp
sudo service ntpd start
sudo tzselect
For Ubuntu Linux:
sudo apt-get install ntp
sudo service ntp start
sudo dpkg-reconfigure tzdata

8. Configure Bamboo home settings

  1. Open <Bamboo installation directory>/atlassian-bamboo/WEB-INF/classes/bamboo-init.properties.
  2. Uncomment the following lines:
    • bamboo.home
    • bamboo.shared.home 
  3. Provide the absolute path to the ${BAMBOO_HOME} and ${BAMBOO_SHARED_HOME} directories.


    Example:

    bamboo.home=/var/bamboo/bamboo-home
    
    bamboo.shared.home=bamboo-san:/bamboo-shared

9. Start the first cluster node installation

Start Bamboo instance and provide your Bamboo Data Center license. If you need a Bamboo Data Center license, you can purchase one that fits your needs, or, get an evaluation license. Then provide necessary DB connection settings and admin user credentials.


Install and configure your load balancer

Step 1. Configure protocols and health checks on your load balancer

Your load balancer must proxy the following protocols:

Protocol

Typical port on the load balancer

Typical port on the Bamboo cluster nodes

Notes

HTTP

80

8085

HTTP mode. Session affinity ("sticky sessions") should be enabled using the 52-character BAMBOOSESSIONID cookies.

HTTPS

443

8085

HTTP mode. Terminating SSL at the load balancer and running plain HTTP to the Bamboo cluster nodes is highly recommended.

TCP

54663

54663

TCP mode. For remote agents connection

Your load balancer must support session affinity ("sticky sessions") using the BAMBOOSESSIONID cookie. Bamboo Data Center assumes that your load balancer always directs each user's requests to the same cluster node. If it does not, users may be unexpectedly logged out or lose other information that may be stored in their HTTP session.

When choosing a load balancer, it must support the HTTP, HTTPS, and TCP protocols. Note that:

  • Apache does not support TCP mode load balancing.

  • HAProxy versions older than 1.5.0 do not support HTTPS.


If your load balancer supports health checks of the cluster nodes, configure it to perform a periodic HTTP GET of http://<bamboo>:8085/rest/api/latest/status, where <bamboo> is the cluster node's name or IP address. This returns one of two HTTP status codes:

  • 200 OK

  • 500 Internal Server Error

If a cluster node does return 200 OK within a reasonable amount of time, the load balancer should direct traffic to it. 

You should then be able to navigate to http://<load-balancer>/, where <load-balancer> is your load balancer's name or IP address. This will take you to your Bamboo Server front page. 

Example of a load balancer configuration...

If you don't have a particular preference or policy for load balancers, you can use HAProxy which is a popular Open Source software load balancer.

If you choose HAProxy, you must use a minimum version of 1.5.0. Earlier versions of HAProxy do not support HTTPS.

To check which version of HAProxy you use, run the following command:

haproxy --version

Here is an example haproxy.cfg configuration file (typically found in the location /etc/haproxy/haproxy.cfg.  This assumes:

  • Your Bamboo cluster nodes are at address 192.168.0.1 and 192.168.0.2, listening on the default ports 8085 (HTTP) and 54663 (TCP). 

  • Users will connect to HA Proxy on port 80 with their browser

  • You have a valid SSL certificate at /etc/cert.pem

global
    log 127.0.0.1   local0
    log 127.0.0.1   local1 debug
    maxconn 4096

defaults
    log     global
    mode    http
    option  httplog
    option  dontlognull
    retries 3
    option redispatch
    maxconn 2000
    timeout connect      5000
    timeout client      50000
    timeout server      50000

frontend localnodes
    bind *:80
    mode http
#    stats enable
#    stats uri /haproxy?stats
#    stats realm Strictly\ Private
#    stats hide-version
#    stats auth admin:SECRET_PASSWORD
    default_backend nodes

frontend mainjms
    bind *:54663
    option tcplog
    mode tcp
    default_backend brokers

    mode http
    balance roundrobin
    option forwardfor

    option httpchk GET /rest/api/latest/status HTTP/1.1\r\nHost:\ 127.0.0.1
    cookie BAMBOOSESSIONID insert nocache
    server bamboo1 192.168.0.1:8085 check cookie bamboo1
#    server bamboo2 192.168.0.2:8085 check cookie bamboo2
    
backend brokers
    mode tcp
    option httpchk GET /rest/api/latest/status HTTP/1.1\r\nHost:\ 127.0.0.1
    server bambooTcp1 192.168.0.1:54663 check port 54663
#    server bambooTcp2 192.168.0.2:54663 check port 54663

Review the contents of the haproxy.cfg file carefully, and customize it for your environment. See http://www.haproxy.org/  for more information about installing and configuring haproxy.

Once you have configured the haproxy.cfg file, start the haproxy service.

sudo service haproxy start

You can also monitor the health of your cluster by navigating to HAProxy's statistics page at http://<load-balancer-url>/haproxy?stats. You need to uncomment stats section in the config file first.


2. Configure Bamboo Server proxy settings

You must include these details into the Connector tag in every node of <bamboo-installation-folder>/conf/server.xml:

<Connector
    ...

    proxyName="<INSERT THE LOAD BALANCER URL>"
    proxyPort="80"
    scheme="http"
>
  ...
</Connector>

3. Change base-url and client-broker-url


  1. In Bamboo, go to  > System > General configuration.
  2. Set the Base URL and broker client URL.


4. Add a new Bamboo application node to the cluster

  1. Copy Bamboo install dir and <BAMBOO_HOME/bamboo.cfg.xml> from Node 1.

  2. Start Bamboo at Node 2.

  3. Check logs if it was able to connect to DB, create necessary local home folders and waiting for lock acquiring

5. Connect the new Bamboo cluster node to the load balancer 

If you are using your own hardware or software load balancer, consult your vendor's documentation on how to add the new Bamboo cluster node to the load balancer.

If you are using HAProxy, in your haproxy.cfg file uncomment the following lines:

server bamboo2 192.168.0.2:8085 check cookie bamboo2
server bambooTcp2 192.168.0.2:54663 check port 54663

and restart haproxy:

sudo service haproxy restart

Congratulations!

That's it! Bamboo Data Center is accessible under the following URL: http://<load-balancer-url>:<port>
