我正在使用Ansible安装
PHP的Pear包,如下所示：
- name: Add Phergie PEAR channel.
command: pear channel-discover pear.phergie.org
ignore_errors: yes
- name: Install Phergie and related plugins.
command: pear install pear.phergie.org/{{ item }}
with_items:
- Phergie
- Phergie_Plugin_AltNick
ignore_errors: yes
ignore_errors是必需的,因为pear在运行之前已成功运行/完成的命令时总是报告错误(例如：
TASK: [Add Phergie PEAR channel.] *********************************************
Failed: [10.31.9.210] => {"changed": true,"cmd": ["pear","channel-discover","pear.phergie.org"],"delta": "0:00:01.089340","end": "2013-12-27 10:16:25.640083","item": "","rc": 1,"start": "2013-12-27 10:16:24.550743"}

是否有更好(更幂等)的方式来运行pear命令,而不必滚动一堆大的,红色忽略的错误？
从Ansible v2开始,有一个额外的模块用于管理PEAR扩展：
http://docs.ansible.com/ansible/pear_module.html
所以现在你可以使用：
- pear: name=Net_URL2 state=latest
