- hosts: home #对应/etc/ansible/hosts的组或者ip remote_user: root #执行用户 tasks: #任务 - name: install httpd #任务名 yum: name=httpd state=present - name: install net-tools yum: name=net-tools state=present - name: install tree yum: name=tree state=present - name: restart httpd service: name=httpd state=restarted
notify和handlers的使用
- hosts: home remote_user: root tasks: - name: install httpd yum: name=httpd state=present notify: #执行完install httpd后，再触发下一个任务事件 - restart httpd #任务事件名 - name: install net-tools yum: name=net-tools state=present - name: install tree yum: name=tree state=present handlers: 被触发的事件，对应上面notify - name: restart httpd service: name=httpd state=restarted tags: rehttpd
tags使用
- hosts: home remote_user: root tasks: - name: install httpd yum: name=httpd state=present notify: - restart httpd - name: install net-tools yum: name=net-tools state=present - name: install tree yum: name=tree state=present handlers: - name: restart httpd service: name=httpd state=restarted tags: rehttpd #标记这个任务，名字可以自定义
ansible-playbook --tags=rehttpd cs.yml #只执行文件里面rehttpd的任务
ansible-playbook --skip-tags=rehttpd cs.yml #排除rehttpd任务，执行其他任务
使用sudo执行任务
tasks: - name: run df -h sudo_user: test #账号 sudo: yes #使用sudo执行 shell: name=df -h
when使用
- hosts: gs remote_user: root tasks: - name: install httpd yum: name=httpd state=installed notify: - restart httpd when: - ansible_distribution == "Centos" #满足条件系统为centos - ansible_distribution_major_version == "6" #满足条件系统为centos6，两个条件都满足才能执行这个任务 - name: install net-tools yum: name=net-tools state=installed - name: install tree yum: name=tree state=installed handlers: - name: restart httpd service: name=httpd state=restarted tags: rehttpd
- hosts: gs remote_user: root tasks: - name: install httpd yum: name=httpd state=installed notify: - restart httpd when: (ansible_distribution == "CentOS" and ansible_distribution_major_version == "7") or (ansible_distribution == "Centos" and ansible_distribution_major_version == "6") #满足系统是centos7或者centos6就可以执行 - name: install net-tools yum: name=net-tools state=installed - name: install tree yum: name=tree state=installed handlers: - name: restart httpd service: name=httpd state=restarted tags: rehttpd
整个任务里面有出现重复调用同个模板，可以使用with_items让用同个模板的任务在一个任务里面完成
- name: "Add groups" #创建用户组 group: name={{ item.name }} state=present with_items: - { name: "zhang" } #创建用户组zhang - { name: "zhao" } #创建用户组zhao tags: - Add_group
- name: "Add Users" #创建账号 user: name={{ item.name }} state=present groups={{ item.groups }} with_items: - { name: "hu", groups: "zhang" } - { name: "zhi", groups: "zhao" } tags: - Add_users
- name: "userdel user" #删除账号 user: name={{ item.name }} state=absent remove=yes with_items: - { name: "hu" } - { name: "zhi" } - { name: "zhangsan" } - { name: "lisi" } - { name: "zhaosi" } - { name: "zhangsi" } - { name: "test1" } tags: - Del_Users
