Ansible Nginx Management configuration file

L most of the time in a production environment, you need to manage the configuration files, and the installation packages are only used when initializing the environment. Let's write a playbook to manage nginx configuration files.

L mkdir-p/etc/ansible/nginx_config/roles/{new,old}/{files,handlers,vars,tasks}

LwhichNewTo be used for the update, Oldused for rollback,FilesBelow isnginx.confand thevhostsdirectory,handlersRestartNginxCommands for services

L first put nginx.conf and the vhosts The catalog is placed in Files directory below

L cd/usr/local/nginx/conf/

L cp-r nginx.conf vhosts/etc/ansible/nginx_conf/roles/new/files/

L vim/etc/ansible/nginx_config/roles/new/vars/main.yml// Defining Variables

L Nginx_basedir:/usr/local/nginx

L vim/etc/ansible/nginx_config/roles/new/handlers/main.yml// To define a reload Nginx Service

L -Name:restart Nginx

L copy:src={{Item.src}} dest={{nginx_basedir}}/{{item.dest}} backup=yes owner=root group=root mode=0644

L With_items:
