和文件处理相关的模块

botang

1. 文件在管理结点上：
copy： 改内容

1. - name: For dev
   
2. copy:
   
3. content: "Development"
   
4. dest: /etc/issue
   
5. when: ansible_hostname in groups['dev']

复制代码

file： 创建目录和链接:

1. - name: Create directory /webdev
   
2. file:
   
3. path: /webdev
   
4. state: directory
   
5. recurse: yes
   
6. group: webdev
   
7. mode: '2775'
   
8. setype: httpd_sys_content_t

复制代码

1. - name: Create link file
   
2. file:
   
3. src: /webdev
   
4. dest: /var/www/html/webdev

复制代码

template： 活的内容的file

1. - name: Create hosts for dev
   
2. template:
   
3. src: hosts.j2
   
4. dest: /etc/myhosts
   
5. when: ansible_hostname in groups['dev']

2. 文件在受管结点上：
geturl:

1. - name: Get hwreport file to /root/hwreport.txt
   
2. get_url:
   
3. url: http://classroom.example.com/content/hwreport.empty
   
4. dest: /root/hwreport.txt

3. 处理内容最强的模块：

1. - name: Ensure SELinux is set to enforcing mode
   
2.   lineinfile:
   
3.     path: /etc/selinux/config
   
4.     regexp: '^SELINUX='
   
5.     line: SELINUX=enforcing
   
6. 
   
7. - name: Make sure group wheel is not in the sudoers configuration
   
8.   lineinfile:
   
9.     path: /etc/sudoers
   
10.     state: absent
    
11.     regexp: '^%wheel'
    
12. 
    
13. - name: Replace a localhost entry with our own
    
14.   lineinfile:
    
15.     path: /etc/hosts
    
16.     regexp: '^127\.0\.0\.1'
    
17.     line: 127.0.0.1 localhost
    
18.     owner: root
    
19.     group: root
    
20.     mode: '0644'
    
21. 
    
22. - name: Ensure the default Apache port is 8080
    
23.   lineinfile:
    
24.     path: /etc/httpd/conf/httpd.conf
    
25.     regexp: '^Listen '
    
26.     insertafter: '^#Listen '
    
27.     line: Listen 8080
    
28. 
    
29. - name: Ensure we have our own comment added to /etc/services
    
30.   lineinfile:
    
31.     path: /etc/services
    
32.     regexp: '^# port for http'
    
33.     insertbefore: '^www.*80/tcp'
    
34.     line: '# port for http by default'
    

复制代码

1. - name: Insert/Update eth0 configuration stanza in /etc/network/interfaces
   
2.         (it might be better to copy files into /etc/network/interfaces.d/)
   
3.   blockinfile:
   
4.     path: /etc/network/interfaces
   
5.     block: |
   
6.       iface eth0 inet static
   
7.           address 192.0.2.23
   
8.           netmask 255.255.255.0

--------进行测试：

1. ---
   
2. - name: Test file
   
3.   hosts: servera
   
4.   tasks:
   
5.   - name: File
   
6.     file:
   
7.       path: /tmp/block.txt
   
8.       state: touch
   
9. 
   
10.   - name: Block
    
11.     blockinfile:
    
12.       path: /tmp/block.txt
    
13.       block: |
    
14.         iface eth0 inet static
    
15.             address 192.0.2.23
    
16.             netmask 255.255.255.0
