1. Case 1: Create jinja2 of nginx main configuration file
1) the preparation of jinja2 nginx main configuration file
1 [root@test-1 jinja2]# vim /ansible/jinja2/test.yaml 2 [root@test-1 jinja2]# cat /ansible/jinja2/test.yaml 3 --- 4 - hosts: web1 5 vars: 6 http_prot: 80 7 server_name: test.scajy.cn 8 9 tasks: 10 - name: copy nginx config file 11 template: 12 src: site.j2 13 dest: /etc/nginx/conf.d/site2.conf 14 notify: reload nginx 15 16 handlers: 17 - name: reload nginx 18 service: 19 name: nginx 20 state: reloaded
2) create the nginx jinja2 of site.j2 profile
1 [root@test-1 jinja2]# cat /ansible/jinja2/site.j2 2 server { 3 listen {{http_prot}}; 4 server_name {{server_name }}}; 5 location / { 6 root /var/www/html; 7 index index.html; 8 } 9 }
3) perform a remote installation
1 [root@test-1 jinja2]# ansible-playbook test.yaml 2 3 PLAY [web1] ************************************************************************************************************************************************************* 4 5 TASK [Gathering Facts] ************************************************************************************************************************************************** 6 ok: [192.168.200.133] 7 ok: [192.168.200.132] 8 9 TASK [copy nginx config file] ******************************************************************************************************************************************* 10 changed: [192.168.200.132] 11 changed: [192.168.200.133] 12 13 RUNNING HANDLER [reload nginx] ****************************************************************************************************************************************** 14 changed: [192.168.200.132] 15 changed: [192.168.200.133] 16 17 PLAY RECAP ************************************************************************************************************************************************************** 18 192.168.200.132 : ok=3 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 19 192.168.200.133 : ok=3 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
4) remote test whether the group is normal web1
1 [root@test-1 jinja2]# curl 192.168.200.132 -H "Host:test.scajy.cn" 2 hello Ansible 3 [root@test-1 jinja2]# curl 192.168.200.133 -H "Host:test.scajy.cn" 4 hello Ansible
2. Case 2: Create jinja2 the upstream nginx reverse proxy configuration test
1) the preparation of jinja2 nginx main configuration file
1 [root@test-1 jinja2]# vim /ansible/jinja2/test.yaml 2 [root@test-1 jinja2]# cat /ansible/jinja2/test.yaml 3 --- 4 - hosts: web1 5 vars: 6 http_prot: 80 7 server_name: test.scajy.cn 8 9 tasks: 10 - name: copy nginx config file 11 template: 12 src: site.j2 13 dest: /etc/nginx/conf.d/site2.conf 14 notify: reload nginx 15 16 handlers: 17 - name: reload nginx 18 service: 19 name: nginx 20 state: reloaded
2) create the nginx jinja2 of site.j2 profile
1 [root@test-1 jinja2]# vim site_upstream.j2 2 [root@test-1 jinja2]# cat site_upstream.j2 3 {% set list=['132','133'] %} 4 upstream {{server_name}} { 5 {% for i in list %} 6 server 192.168.200.{{i}}:80; 7 {% endfor%} 8 9 } 10 11 server { 12 listen {{http_prot}}; 13 server_name {{server_name }}; 14 location / { 15 root /var/www/html; 16 index index.html; 17 } 18 }
3) ansible execution test.yaml file, perform remote installation
1 [root@test-1 jinja2]# ansible-playbook test.yaml 2 3 PLAY [web1] ****************************************************************************************************************************************************************************************************************************************************************** 4 5 TASK [Gathering Facts] ******************************************************************************************************************************************************************************************************************************************************* 6 ok: [192.168.200.132] 7 ok: [192.168.200.133] 8 9 TASK [copy nginx config file] ************************************************************************************************************************************************************************************************************************************************ 10 changed: [192.168.200.132] 11 changed: [192.168.200.133] 12 13 RUNNING HANDLER [reload nginx] *********************************************************************************************************************************************************************************************************************************************** 14 changed: [192.168.200.133] 15 changed: [192.168.200.132] 16 17 PLAY RECAP ******************************************************************************************************************************************************************************************************************************************************************* 18 192.168.200.132 : ok=3 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 19 192.168.200.133 : ok=3 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
4) Remote verify successfully posted
