Ansible deployment source code nginx

vim /etc/ansible/hosts [nginx] 192.168.200.102

• create management directory:

mkdir -p nginx/roles/nginx_install/ cd nginx/

explain:

[root@localhost ~]# tree /etc/ansible/nginx/ /etc/ansible/nginx/ ├── nginx.yml └── roles └── nginx_install ├── files │ └── nginx-1.16.0.tar.gz ├── handlers ├── meta ├── tasks │ ├── copy.yml │ ├── install.yml │ ├── main.yml │ └── prepare.yml ├── templates │ ├── fastcgi_params │ ├── nginx.conf │ ├── nginx.service │ └── server.conf └── vars └── main.yml 8 directories, 11 files

Create nginx entry file to call nginx? Install:

[root@localhost nginx]# cat nginx.yml - hosts: nginx remote_user: root gather_facts: True roles: - nginx_install

• create variables:

[root@localhost nginx]# cat roles/nginx_install/vars/main.yml NGINX_VER: 1.16.0 NGINX_USER: nginx NGINX_PORT: 80 SOURCE_DIR: /software NGINX_DIR: /usr/local/nginx DATA_DIR: /data/nginx

• create template file:
