详解ansible批量管理服务(3)
运行剧本
root@m01 ansible_playbook]#ansible-playbook -C test_判断功能.yaml PLAY [nfs_client] ************************************************************************************ TASK [Gathering Facts] ******************************************************************************* ok: [172.16.1.41] ok: [172.16.1.7] TASK [create file for 41 host] *********************************************************************** skipping: [172.16.1.7] changed: [172.16.1.41] TASK [create file for 7 host] ************************************************************************ skipping: [172.16.1.41] changed: [172.16.1.7] PLAY RECAP ******************************************************************************************* 172.16.1.41 : ok=2 changed=1 unreachable=0 failed=0 skipped=1 rescued=0 ignored=0 172.16.1.7 : ok=2 changed=1 unreachable=0 failed=0 skipped=1 rescued=0 ignored=0
1.6.4 剧本信息循环功能
循环创建多个用户
[root@m01 ansible_playbook]#vim test_循环功能.yaml - hosts: 172.16.1.41 tasks: - name: create user user: name={{ item }} with_items: - oldgirl01 - oldgirl02 - oldgirl03 - oldgirl04 - oldgirl05
循环创建多个用户 多个用户uid数值是不同的
[root@m01 ansible_playbook]#vim test_循环功能.yaml - hosts: 172.16.1.41 tasks: - name: create user user: name={{ item.name }} uid={{ item.uid }} with_items: - {name: "oldgirl06", uid: "3006"} - {name: "oldgirl07", uid: "3007"} - {name: "oldgirl08", uid: "3008"} - {name: "oldgirl09", uid: "3009"} - name: check create user info shell: grep oldgirl0 /etc/passwd register: user_info - debug: msg={{ user_info.stdout_lines }}
1.6.5 剧本编写忽略错误功能
忽略功能主要用来调试剧本
[root@m01 ansible_playbook]#vim test_h忽略功能.yaml - hosts: 172.16.1.41 tasks: - name: create rsync user shell: useradd rsync -M -s /sbin/nologin ignore_errors: yes - name: create backup dir shell: mkdir /backup ignore_errors: yes - name: boot server shell: systemctl start rsyncd ignore_errors: yes
在使用shell进行一些操作时,shell产生的结果已经存在时,会导致剧本无法进行下去,因此使用忽略功能可以有效的使剧本进行下去。
1.6.6 剧本标签设置功能
标签功能主要用来调试剧本
tags:标签
[root@m01 ansible_playbook]#vim test_标签功能.yaml - hosts: 172.16.1.41 tasks: - name: 01:安装软件 yum: name=rsync state=installed ignore_errors: yes - name: 02:创建用户 user: name=rsync create_home=no shell=/sbin/nologin ignore_errors: yes tags: create_user - name: 03:创建目录 file: path=/backup state=directory
