ansible调用主机报错【已解决】

ansible预计实现功能，自动生成/etc/hosts文件，copy到远程机器；


ansible执行命令报错：

配置如下：

1. ---
   
2. - hosts: 192.168.31.12
   
3.   remote_user: cluster
   
4.   sudo: yes
   
5.   tasks:
   
6.     - name: dirstribute host file
   
7.       template: src=templates/hosts.j2 dest=/tmp/hosts

复制代码

hosts.j2

1. 127.0.0.1 localhost
   
2. {{ ansible_eth0.ipv4.address }}  {{ ansible_hostname }}
   
3. 
   
4. {% for host in groups['all'] %}
   
5. {{ hostvars[host].ansible_eth0.ipv4.address }}  {{ hostvars[host].ansible_hostname }}

固更改hosts.j2文件

1. cat hosts.j2
   
2. 127.0.0.1 localhost
   
3. {{ ansible_eno16777984.ipv4.address }}  {{ ansible_hostname }}
   
4. 
   
5. {% for host in groups['all'] %}
   
6. {{ hostvars[host].ansible_eno16777984.ipv4.address }}  {{ hostvars[host].ansible_hostname }}
   
7. {% endfor %}
   
8. 
   
9. # The following lines are desirable for IPv6 capable hosts
   
10. ::1 ip6-localhost ip6-loopback
    
11. fe00::0 ip6-localnet
    
12. ff00::0 ip6-mcastprefix
    
13. ff02::1 ip6-allnodes
    
14. ff02::2 ip6-allrouters
    
15. ff02::3 ip6-allhosts
