Ansible-playbook实战（二）

cd /root/121.36.40.218/etc/
#进入配置文件放置的目录
cp redis.conf redis.conf.j2 
#复制配置文件为redis.conf.j2 
vim redis.conf.j2 
#编辑变量使其成为模版
bind {ansible_facts['eth0']['ipv4']['address']}
#第61行，应该是两个花括号，我这里两个花括号无法显示
port {redis_port}
#第84行，设置IP地址端口为变量，这里也是两个花括号

ansible all -m setup
#查看模版，确实有ansible_facts这个变量

vim /root/playbooks/redis_third.yaml
#写剧本3

- hosts: all
  remote_user: root
  vars:
    redis: /root/121.36.40.218/etc/redis.conf.j2

  tasks:
  - name: install redis
    yum: name=redis state=latest
  - name: start redis
    service: name=redis state=started
  - name: copy config
    template: src= dest=/etc/redis.conf owner=redis
    #这里使用了模版
    notify: restart redis
    tags: configfile

  handlers:
