How to safely clone a Windows machine.

5. Prior to cloning, you may want to disjoin yourself from any Active Directory (AD) domain. Once disjoined, prep the machine to be imaged with Microsoft Deployment Toolkit's SYSPREP.EXE, (this tool resets items such as Plug 'N Play (PnP) detection, machine-specific state information, and regenerates the machine Security Identifier (SID) - note, this does not update any existing references to the old SID in the registry - or elsewhere- made by other applications. Also, keep in mind this is the only way Microsoft officially supports cloned machines. See Microsoft's documentation for further details on the toolkit and subject). If the source machine is a physical box, use a cloning tool such as Altiris's RapidDeploy, Symantec Ghost, etc. If virtual, use the appropriate vmWare, VirtualBox, or KVM, etc. Virtual Machine (VM) or Virtual Machine Disk (VMDK) cloning methods/tools. Once cloned & deployed, rejoin the domain & optionally run a SID registry update tool, ex: NewSID.

How to create a sample Cassandra Keyspace

6. To create a new keyspace perform the following step.

For a single node, from CQLSH run:

CREATE KEYSPACE IF NOT EXISTS cycling WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };

For a multi-node cluster, verify the Cassandra “datacenter” name (default = dc1) from the CLI by running nodetool status and then from CQLSH run:

CREATE KEYSPACE IF NOT EXISTS cycling WITH REPLICATION = { 'class' : 'NetworkTopologyStrategy', '<datacenter_name>' : <total_number_of_nodes> }; 
-- where <datacenter_name> = the name of the datacenter as shown via nodetool status, and <total_number_of_nodes> = total # of nodes (in the cluster)

How to create sample tables in a Cassandra Keyspace

7. To create sample tables in a keyspace, from CQLSH run:

CREATE TABLE cycling.cyclist_name ( id UUID PRIMARY KEY, lastname text, firstname text );
CREATE TABLE cycling.calendar ( race_id int PRIMARY KEY, race_start_date timestamp, race_end_date timestamp, race_name text );

How to insert sample data into tables in a Cassandra Keyspace

8. To insert sample data into tables in a keyspace, from CQLSH run:

INSERT INTO cycling.cyclist_name (id, lastname, firstname) VALUES (5b6962dd-3f90-4c93-8f61-eabfa4a803e2, 'VOS','Marianne');
INSERT INTO cycling.calendar (race_id, race_start_date, race_end_date, race_name) VALUES (201, '2015-02-18', '2015-02-22', $$Women's Tour of New Zealand$$); -- use "$$"..."$$" if string contains special chars

How to create a new logon user (role) and grant permissions to a sample Cassandra Keyspace

9. To create a new logon user (role) with a password and grant permissions to the sample keyspace, from CQLSH run:

CREATE ROLE cyclingadmin WITH PASSWORD = 'pel0t0n' AND LOGIN = true;
GRANT ALL PERMISSIONS ON KEYSPACE cycling TO cyclingadmin;

DataStax DevCenter

10. You can download DevCenter from https://academy.datastax.com/downloads, you will need a free DataStax Academy account (note, DataStax is the company that was the original chair/conservator of the Apache Cassandra project).

Cassandra Encryption & Performance Optimizations

11. By default, internode encryption is set to: internode_encryption: none. If you wish to enable internode encryption, set this to either all, dc, or rack (where dc = inter-datacenter encryption). You may wish to also change the keystore and truststore passwords to something other than the default. See https://docs.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore for instructions on how to setup a Keystore.

By default, client/server encryption encryption is disabled & optional, ie: enabled: false & optional: false. If you wish to enable this, set enabled to true. If you wish to make this mandatory, set optional to true. You may wish to also change the keystore and truststore passwords to something other than the default. See https://docs.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#CreateKeystore for instructions on how to setup a Keystore.

For performance optimizations, examine https://docs.datastax.com/en/dse/5.1/dse-admin/datastax_enterprise/config/configRecommendedSettings.html (Note, this guide was written for Linux servers originally but some of suggestions may still apply)

Cassandra Consistency Levels

12. Consistency Level (CL) = ALL (CONSISTENCY ALL) means for a given keyspace, a read/write query needs to hear back from ALL nodes, this is the strongest consistency level but obviously the slowest. CL = ONE (CONSISTENCY ONE) means for a given keyspace, a read/write query only needs to hear back from 1 node total, this is one of the weaker consistency levels but faster obviously, this is the default. There is also CL=QUORUM (CONSISTENCY QUORUM;) which means for a given keyspace, a read/write query needs to hear back from a “quorum” of nodes. A quorum = floor ((keyspace_x_in_datacenter_1_rf ... + keyspace_x_in_datacenter_n_rf) / 2 + 1); where RF = Replication Factor & n = nodes keyspace is replicated to, ex: for a 3-node cluster in one DC with keyspace with a RF=3, floor((datacenter1_rf/2)+1) = floor((3/2)+1) = floor(1.5+1) = floor(2.5) = 2; therefore a min of 2 nodes must respond. This a mid-point between CL=ALL and CL=ONE and offers a compromise between a strong consistency level and good performance.

Cassandra Cluster Renaming

13. To rename the cluster, (on each machine if > 1) launch CQLSH, update the cluster name, flush the system table, and restart Cassandra, ie:

13.1. Launch CQLSH (see Appendix C3.2 (for Windows) or Appendix C3.3 (for Linux) below).
13.2. Enter in password (default = `cassandra`, if default, you may wish to change/secure this),
13.3. UPDATE system.local SET cluster_name = 'MyNewClusterName' where key='local'; , where MyNewClusterName = the new name for the cluster
13.4. Exit CQLSH, ie: exit;
13.4. Run nodetool flush system,
13.5. Edit cassandra.yaml (make a backup first),
13.6. Change cluster_name to MyNewClusterName, where MyNewClusterName = the new name for the cluster.
13.7.  Save cassandra.yaml ,
13.8. Restart Cassandra services, ie: sudo systemctl restart cassandra (systemctl status cassandra to verify it re-started correctly, if not, review changes for errors),
13.9. Confirm cluster name change took effect by running nodetool describecluster to verify Cluster name change in output.
13.10. Update firewall settings on server (reload if necessary, ie: sudo firewall-cmd --reload) and/or your cloud provider, ie: AWS, etc.

Appendix C: Syndeia Cloud Installation Instructions

Validate/Configure Cassandra is setup to authenticate

1. Ensure that the Cassandra database is setup to authenticate. Follow the steps below to do this.

1.1. On a Cassandra node, open the .\conf\cassandra.yaml file
1.2. On a Cassandra node, in cassandra.yaml, validate authenticator=PasswordAuthenticator (the default value AllowAllAuthenticator disables authentication and is never safe. For more details, see: http://cassandra.apache.org/doc/latest/configuration/cassandra_config_file.html#authenticator). Save and close the file. (Re)start the Cassandra service.

How to launch a CQLSH session on Windows

2. To launch a CQLSH session on Windows, navigate to the Cassandra bin directory, ex: C:\Program Files\apache-cassandra-3.0.15\bin and run cqlsh -u <username> <cassandra_server_FQDN>, ex: cqlsh -u cassandra myserver.mydomain.com. If you are connecting to localhost, you can optionally omit the servername. You should be prompted for credentials. Enter your credentials to authenticate.

Note, if you get a message saying "Warning: Timezone defined and 'pytz' module for timezone conversion not installed. Timestamps will be displayed in UTC timezone.", install the pytz module using the PIP Installer, ie, in a terminal run: pip install pytz.

How to launch a CQLSH session on Linux

3. To launch a CQLSH session on Linux, run cqlsh -u <username> <cassandra_server_FQDN>, ex: cqlsh -u cassandra myserver.mydomain.com. If you are connecting to localhost, you can optionally omit the servername. You should be prompted for credentials. Enter your credentials to authenticate.

How to create a new syndeia_admin role, confirm creation, and assign permissions

4. To create a new syndeia_admin role with a strong password, run the following, ie:

CREATE ROLE IF NOT EXISTS syndeia_admin WITH LOGIN = true AND PASSWORD = '<syndeia_admin_strong_password>';

where <syndeia_admin_strong_password> is a strong password, ex: ‘M1Str9ngPass80rd'. Then, run the following command to list all roles to confirm syndeia_admin is listed.

LIST ROLES;

cassandra@cqlsh> CREATE ROLE IF NOT EXISTS syndeia_admin WITH LOGIN=TRUE AND PASSWORD='syndeia4all';
cassandra@cqlsh> LIST ROLES;

 role          | super | login | options
---------------+-------+-------+---------
     cassandra |  True |  True |        {}
 syndeia_admin | False |  True |        {}

To grant all permissions on the syndeia keyspace to the syndeia_admin role, run the following, ie:

GRANT ALL PERMISSIONS ON KEYSPACE syndeia TO syndeia_admin;

Note: For more details on the GRANT command, refer to: https://docs.datastax.com/en/cql/3.3/cql/cql_reference/cqlGrant.html?hl=grant

Appendix D: Setting up Services to Start on Boot

How to create a symlink to syndeia-cloud on Windows

1. From CMD.EXE, run mklink /d <link-location-and-name> <destination>, ex:

C:\Program Files\Intercax>mklink /d "c:\Program Files\Intercax\syndeia-cloud-current" "c:\Program Files\Intercax\syndeia-cloud-2018-03-05"
symbolic link created for c:\Program Files\Intercax\syndeia-cloud-current <<===>> c:\Program Files\Intercax\syndeia-cloud-2018-03-05

Note, to delete or update a directory symlink use rmdir <symlink_name> to delete the existing symlink, do not use del as that will delete the contents of the derefenced directory symlink!

How to create a symlikn to syndeia-cloud on Linux

1. From the CLI, run sudo ln -s <destination> <link-location-and-name>, ex:

$ sudo ln -s /opt/icx/syndeia-cloud-2018-03-05/ /opt/icx/syndeia-cloud-current
$

Note, if successful, you will get no output and just see the command prompt again

How to create a Scheduled Task on Windows to start (single node) Cassandra and Syndeia Cloud on boot

1. Launch Task Scheduler
2. Click Create Task...

3. Click Change User or Group... and specify SYSTEM as the account.

4. Click the Trigger tab and create a new trigger of "At startup".

5. Click the Actions tab and create one Action of "Start a program" to start Cassandra and specify LEGACY in the Add arguments field and C:\Program Files\apache-cassandra-<version>\bin in the Start in field

Do not encapsulate the Start in path with quotes!

6. Click Create Task... and specify a Trigger of "At startup" and two Actions of "Start a program" to start: 1. a script to wait for the Cassandra port, and 2. Syndeia Cloud

a. Action 1: create the following batch file (ex: c:\Program Files\apache-cassandra-<version>\bin\wait_for_cassandra_port.bat)

:while 
netstat -afp tcp | findstr ":9042"
if %errorlevel% NEQ 0 (goto :while)

... and reference it in the "Start a program" Action by specifying c:\Program Files\apache-cassandra-<version>\bin\wait_for_cassandra_port.bat in the Program/script field.

b. Action 2: create a "Start a program" Action to start syndeia-cloud.bat. Make sure this is sequenced after the first action.

To prevent any breakage when Syndeia Cloud is upgraded, reference the symlink path VS the current installed version of Syndeia Cloud (see Appendix D4.1 for more details)
