1. Create roles directory
mkdir -p ansible_nginx/group_vars
mkdir -p ansible_nginx/roles
cd ansible_nginx/roles
mkdir common nginx
mkdir {common,nginx}/tasks
mkdir nginx/{files,handlers}
mkdir nginx/templates
2. Basic Configuration of Roles
cd ansible_nginx
2.1. Hosts Configuration
cat hosts
[webservers]
192.168.52.16
2.2. site.yml Configuration
cat site.yml
---- name: Install nginx hosts: webservers remote_user: root roles: - role: common - role: nginx tags: ["nginx"]2.3. group_vars Configuration
cat group_vars/all
—
# ssh
ansible_ssh_user: root
ansible_ssh_pass: cjm@168
2.4. Common Configuration
cat roles/common/tasks/main.yml
---- name: Install deps yum: name={{ item }} state=present with_items: - gcc - make - zlib-devel - openssl-devel - pcre-devel2.5. Nginx Configuration
cat roles/nginx/files/nginx.conf

ansible-playbook site.yml –syntax-check # Syntax check
ansible-playbook -i hosts site.yml
4. Nginx Login Verification
mkdir /var/www/html -p
echo ‘hello to my site’ > /var/www/html/index.html
/usr/local/nginx/sbin/nginx -s reload
