1. Quick Start to KVLite
  2. Start KVLite

Start KVLite

Perform the following steps to start a KVLite instance:

You could start KVLite in secure mode (the default option) or non-secure mode. If the KVLite is started in a secure mode, you should also configure a secure proxy and start it. Similarly if the KVLite is started in a non-secure mode, a non-secure proxy needs to be configured and started.

The following environmental variables have to be set before invoking the script to start KVLite as these variables are used in the scripts.

Table - Environment variables

Name of the variable Description Sample values
KV_HOST Identifies a host name associated with the node on which the script to configure kvlite is run. localhost or the name of the machine
KV_PROXY_PORT The TCP/IP port on which proxy should be contacted.

Non-Secure proxy: Use 80 if root privilege is there, else 8080

Secure proxy: Use 443 if root privilege is there, else 8443
KV_HARANGE A range of free ports that the Replication Nodes and Admins use to communicate among themselves. These ports should be sequential. 5010-5020
KV_SERVICERANGE A range of ports that may be used for communication among administrative services running on a Storage Node and its managed services. 5021-5049
KV_PORT The TCP/IP port on which Oracle NoSQL Database should be contacted. Sometimes referred to as the registry port. 5000
KV_ADMIN_PORT The TCP/IP port on which the admin service should be started. 5999

Start KVLite in secure mode:

  • Download and extract the zipped file (start_securekvlite.zip) into the directory where you extracted kvlite. This zipped file contains the scripts needed for starting KVLite in secure mode.
  • Invoke the script (start_kvlite.sh) to start KVLite in secure mode. 
    $/bin/bash start_kvlite.sh
    You get an output as shown below:
    Waiting for kvstore to start...

Generated password for user admin:*********
User login file: kvroot/security/user.security
Created new kvlite store with args:
-root kvroot -store kvstore -host localhost -port 5000 -admin-web-port 5999 -secure-config enable
  • Configure proxy for the secure kvlite: You need to do the following to configure a secure proxy:
    • Create a user (proxy_user) as the proxy needs an identity to connect to the secure data store.

    • Create a new password file to store the credentials needed to login as the proxy user.

    • Create a login file proxy.login for the proxy user.
    • Create self-signed certificates that can be used to securely connect to the Oracle NoSQL Database Proxy.
    Invoke the script (setup-http-proxy-sec.sh) to configure proxy in secure mode. 
    $ /bin/bash setup-http-proxy-sec.sh
    You get an output as shown below:
    Creating password

  • Use the script (start_proxy.sh) to start the proxy for a secure data store:
    /bin/bash start_proxy.sh
    You get an output as shown below:

Start KVLite in non-secure mode:

  • Download and extract the zipped file (start_nonsecurekvlite.zip) into the directory where you extracted kvlite. This zipped file contains the scripts needed for starting KVLite in non-secure mode.
  • Invoke the script (start_nonsecure_kvlite.sh) to start KVLite in non-secure mode. 
    $/bin/bash start_nonsecure_kvlite.sh
    You get an output as shown below:
    Created new kvlite store with args: -root kvroot -store kvstore -host localhost
-port 5000 -admin-web-port 5999 - secure-config disable
  • Use the script (start_nonsecure_proxy.sh) to start the proxy for a non-secure data store:
    $/bin/bash start_nonsecure_proxy.sh
    You get an output as shown below:
