I have been automating and centralizing dba and system administration processes using Python recently. One of the problems I solved was how to create Bash and SQL scripts to run on the remote database servers, copy them to the database servers and then execute them as another Linux account. After I got my Python scripts working perfectly, I discovered that I had re-invented Ansible 🙂
My scripts would have been much less complex and easier to write if I had done them with Ansible in mind. So that’s how I will write them going forward. I also wanted to implement a DBA Data Warehouse so I added cx_Oracle to the mix and used it to store the admin data in a database. I have been using a local virtual machine for Python development and the database was just a local installation on the VM.
Before moving to production I needed to figure out an easy way to get this stuff installed on the production Linux box. Setting it up on my VM was an adventure in Googling and trial and error. So here’s the documentation on how to set it up. You need to define the shell variables first.
export http_proxy=http://$my_userid:$my_password@$proxy_server:$port export https_proxy=https://$my_userid:$my_password@$proxy_server:$port wget https://bootstrap.pypa.io/ez_setup.py -O - | python easy_install pip export ORACLE_HOME=/base/oracle/product/12102 export LD_LIBRARY_PATH=$ORACLE_HOME/lib yum install python-devel pip install --proxy=https://$my_userid:$my_pasword@$proxy_server:$port cx_Oracle pip install --proxy=https://$my_userid:$my_pasword@$proxy_server:$port ansible
