| # Apache Trafodion Python Installer |
| |
| ## Prerequisite: |
| |
| - CDH/HDP is installed on Trafodion nodes with web UI enabled, or Apache Hadoop, HBase is installed on the same directory on all nodes |
| - /etc/hosts contains hostname info for all Trafodion nodes on **installer node** |
| - python version 2.6/2.7, and python library `httplib2`, `prettytable` |
| - Trafodion server package file is stored on **installer node** |
| - Passwordless SSH login, one of these two options is needed: |
| - Set SSH key pairs against **installer node** and Trafodion nodes |
| - Install `sshpass` tool on **installer node**, then input the SSH password during installation using `--enable-pwd` option |
| |
| > **installer node** can be any nodes as long as it can ssh to Trafodion nodes, it also can be one of the Trafodion nodes |
| |
| ## How to use: |
| - Two ways: |
| - Simply invoke `./db_install.py` to start the installation in guided mode |
| - Copy `configs/db_config_default.ini` file to `your_db_config` and modify it, then invoke `./db_config.py --config-file your_db_config` to start installation in config mode |
| - For a quick install with default settings, you only need to put Trafodion package file in installer's directory, provide CDH/HDP web URL in `your_db_config` file and then it's ready to go! |
| - Use `./db_install.py --help` for more options |
| - Invoke `./discovery.py` to get the system basic info on all nodes |
