问题
Initially I used a makefile to deploy my application in linux.
I had various sed commands to replace variables like the PHP upload file size, post size, log file location etc.
Now I am shifting to ansible. I know I can copy the files, but how can I make changes to the conf files? Like if i just want to change the upload_filesize = 50M parameter. I don't want to make copies of the whole conf file and then replace with my file.
Sometimes it’s only a one-line change. Is there any better way to edit the config files in ansible?
回答1:
If it's an INI file, then your specific requirements can be probably met by ini_file module (http://docs.ansible.com/ini_file_module.html).
If your change is limited just few lines (or eve one), then you can probably look at lineinfile module (http://docs.ansible.com/lineinfile_module.html).
Should you however need to change large number of settings, then it may be more beneficial to use template (http://docs.ansible.com/template_module.html) or assemble (http://docs.ansible.com/assemble_module.html). The main disadvantage of this approach is that you may need to review your template or fragments when updating your dependency.

Depending on the operating system, you can add files here /etc/php/apache2/conf.d/10-someinifilewithsetting.ini
