同时建立多个目录的yml,
html
- hosts: testhost vars_files: - /tmp/vars.yml tasks: - name: use disk name make dir command: mkdir -p "/tmp/{{ dict_1.a }}/{{ dict_1.b }}/{{ dict_1.c }}" "/tmp/{{ dict_2['a'] }}/{{ dict_2['b'] }}/{{ dict_2['c'] }}" "/tmp/{{ list_1[0] }}/{{ list_1[1] }}/{{ list_1[2] }}" "/tmp/{{ list_2[0] }}/{{ list_2[1] }}/{{ list_2[2] }}"
额外变量文件 vars.ymlpython
--- dict_1: #yml 注释能够随便折腾 a: AA #缩进必须用空格 b: BB c: CC dict_2: { a: D1, b: D1, c: D1 } #字典也能够这样 list_1: - 11 - 22 - 33 list_2: [ L1, L2, L3 ] #列表也能够这样
结果:shell
root@svntest:/tmp# ll total 40 drwxrwxrwx 6 root root 20480 May 17 14:14 ./ drwxr-xr-x 24 root root 4096 Dec 18 2013 ../ drwxr-xr-x 3 root root 4096 May 17 14:14 11/ drwxr-xr-x 3 root root 4096 May 17 14:14 AA/ drwxr-xr-x 3 root root 4096 May 17 14:14 D1/ drwxr-xr-x 3 root root 4096 May 17 14:14 L1/
判断apache2进程是否存在,不存在就启动apache
--- - hosts: testhost tasks: - shell: netstat -tunlp | grep ":80 " | wc -l register: result # - debug: msg="MSG {{ result }} END" - command: /etc/init.d/apache2 start when: result.stdout == "0" - hosts: testc tasks: - debug: msg="EEE {{ hostvars.testhost.result.stdout }}" #访问 testhost 的result变量
使用 /etc/ansible/hosts 中的相关主机centos
[test] testhost centostest
相关 yml 调用bash
- debug: msg="{{ groups.test[0] }}"
