一、setup
1 ansible_all_ipv4_addresses # ipv4的所有地址 2 ansible_all_ipv6_addresses # ipv6的所有地址 3 ansible_date_time # 获取到控制节点时间 4 ansible_default_ipv4 # 默认的ipv4地址 5 ansible_distribution # 系统 6 ansible_distribution_major_version # 系统的大版本 7 ansible_distribution_version # 系统的版本号 8 ansible_domain #系统所在的域 9 ansible_env #系统的环境变量 10 ansible_hostname #系统的主机名 11 ansible_fqdn #系统的全名 12 ansible_machine #系统的架构 13 ansible_memory_mb #系统的内存信息 14 ansible_os_family # 系统的家族 15 ansible_pkg_mgr # 系统的包管理工具 16 ansible_processor_cores #系统的cpu的核数(每颗) 17 ansible_processor_count #系统cpu的颗数 18 ansible_processor_vcpus #系统cpu的总个数=cpu的颗数*CPU的核数 19 ansible_python # 系统上的python 20 ansible cache -m setup -a 'filter=*processor*' # 用来搜索
1 - hosts: db 2 remote_user: root 3 tasks: 4 - name: createfile 5 copy: content="大弦嘈嘈如急雨" dest=/tmp/a.txt 6 when: a=="3" 7 - name: cratefile 8 copy: content="小弦切切如私语" dest=/tmp/a.txt 9 when: a=="4"
三、tags 可以指定执行部分任务
1 - hosts: web 2 tasks: 3 - name: installnginx 4 yum: name=nginx 5 - name: copyfile 6 copy: src=/etc/nginx/nginx.conf dest=/etc/nginx/nginx.conf 7 tags: copyfile 8 - name: start 9 service: name=nginx state=started 10
四、循环 with_items
1 - hosts: web 2 tasks: 3 - name: crateuser 4 user: name={{item}} 5 with_items: 6 - user1 7 - user2 8 - user3
嵌套循环
1 - hosts: web 2 tasks: 3 - name: crategroup 4 group: name={{item}} 5 with_items: 6 - wulaoshi30 7 - wulaoshi31 8 - wulaoshi32 9 - name: createuser 10 user: name={{item.name}} group={{item.group}} # 循环每个字典取值 11 with_items: 12 - {'name':alex40,'group':wulaoshi30} 13 - {'name':alex41,'group':wulaoshi31} 14 - {'name':alex42,'group':wulaoshi32}
template模块
template模块和copy模块的区别
-
-
template模块替代参数
1 - hosts: web 2 tasks: 3 - name: installredis 4 yum: name=redis 5 - name: copyfile 6 template: src=redis.conf dest=/etc/redis.conf 7 - name: start 8 service: name=redis state=started
在本机的redis的配置文件里bind 的ip随被控管机改变而改变
bind {{ ansible_default_ipv4.address }}
