ansible-初始playbook安装nginx

1. ansible-初始playbook安装nginx

1) 创建一个ansible存放路径

1 [root@test-1 scripts]# mkdir -p /ansible/nginx/{conf,bin}

2) 验证存放路径

1 [root@test-1 bin]# tree /ansible/
2 /ansible/
3 └── nginx
4     ├── bin
5     │   └── nginx.yaml
6     └── conf
7         └── site.conf
8
9 3 directories, 2 files

2. 编写playbook的nginx安装yaml文件

1) 编写nginx.yaml配置文件

 1 [root@test-1 bin]# vim /ansible/nginx/bin/nginx.yaml
 2 [root@test-1 bin]#cat /ansible/nginx/bin/nginx.yaml
 3 - hosts: web1
 4   remote_user: root
 5   vars:
 6     hello: Ansible
 7
 8   tasks:
 9   - name: Add repo
10     yum_repository:
11       name: nginx
12       description: nginx repo
13       baseurl: http://nginx.org/packages/centos/7/$basearch/
14       gpgcheck: no
15       enabled: 1
16   - name: Install nginx
17     yum:
18       name: nginx
19       state: latest
20   - name: Copy nginx configuration file
21     copy:
22       src: /ansible/nginx/conf/site.conf
23       dest: /etc/nginx/conf.d/site.conf
24   - name: Start nginx
25     service:
26       name: nginx
27       state: started
28   - name: Create wwwroot directory
29     file:
30       dest: /var/www/html
31       state: directory
32   - name: Create test page index.html
33     shell: echo "hello {{hello}}" > /var/www/html/index.html

2) 编写nginx的配置文件

 1 [root@test-1 bin]# vim /ansible/nginx/conf/site.conf
 2 [root@test-1 bin]# cat /ansible/nginx/conf/site.conf
 3 server {
 4     listen 80;
 5     server_name www.ctnrs.com;
 6     location / {
 7         root   /var/www/html;
 8         index  index.html;
 9     }
10 }

3. 验证playbook是否正确

1) 验证

1 [root@test-1 bin]# ansible-playbook /ansible/nginx/bin/nginx.yaml  --syntax-check
2 [WARNING]: log file at /var/log/ansible/ansible.log is not writeable and we cannot create it, aborting
3
4
5 playbook: /ansible/nginx/bin/nginx.yaml

提示：
       验证配置文件正确，没问题

4. 执行ansible-playbook远程安装

1) 执行安装nginx

 1 [root@test-1 bin]# ansible-playbook /ansible/nginx/bin/nginx.yaml

2 hello Ansible
3 [root@test-1 scripts]# curl 192.168.200.133 -H "Host:www.ctnrs.com"
