ansible playbook to manually compile and install new kernel on Centos/Redhat Linux

Script needs an inventory file when run against real servers. For local testing with vagrant use hosts: all

For silent kernel compile, a kernel config file with required kernel configs options is required. This can be obtained by manually compiling the kernel on one of the hosts. Resulting.config can be found inside the folder where the kernel is compiled. This playbook expect the kernel config file (kernel.config) file to be in the same folder as playbook upgrade.yml.

A sample kernel config with default options are included in the script folder.

syntax to run the script is

ansible-playbook upgrade.yml -i inventory.yml -u root -k

This is tested with ansible 2.0 and vagrant 1.8.4.

For vagrant the ansible verbosity can be increased with ansible.verbose = "vvv" if desired. Currently following are under a single task,

• make silentoldconfig .config
• make
• make modules
• make modules_install
• make install

If desired they can be broken down to individual tasks so the result of each sub task is displayed.
