Puppet学习：Augeas的怪问题

今天测试部署Zabbix，本来以前是正常的，今天莫名其妙报错。测试后发现是Augeas出现问题，无论如何都不执行。于是采用调试模式：

puppet agent --test --verbose --debug

然后捕捉到了下面的信息：

Debug: Augeas[update-php-parma](provider=augeas): Opening augeas with root /, lens path , flags
Debug: Augeas[update-php-parma](provider=augeas): Augeas version 0.9. is installed

首先，没有修改过ntp.conf文件，所以很纳闷啊~（呵呵，刚想起来，ntp.conf中的server写成service，所以才会报错，一个小坑……）

在app_zabbix::conf中的配置节是这么写的

augeas {"update-php-parma" :
    context     =>  "/etc/php.ini",
    changes     =>  [
        "set PHP/date.timezone Asia/Shanghai",
        "set PHP/post_max_size 16M",
        "set PHP/max_execution_time 300",
        "set PHP/max_input_time 300",
        "set MySQL/mysql.default_socket /mysql/var/mysql.sock",
        ],
    notify      =>  Service["httpd"],
}

后来在测试机上测试了下，需要安装augeas：

augtool> set "/etc/php.ini/PHP/date.timezone" "Asia/Shanghai"
augtool> save
augtool> get "/etc/php.ini/PHP/date.timezone"
/etc/php.ini/PHP/date.timezone = Asia/Shanghai

直接在命令行中执行就失败（话说我写日志的时候就OK了，之前怎么弄都无法写入）。

呃……解决办法是，所有的context都必须是/files下的，如

augeas {"update-php-parma" :
    context     =>  "/files/etc/php.ini",
    changes     =>  [
        "set PHP/date.timezone Asia/Shanghai",
        "set PHP/post_max_size 16M",
        "set PHP/max_execution_time 300",
        "set PHP/max_input_time 300",
        "set MySQL/mysql.default_socket /mysql/var/mysql.sock",
        ],
    notify      =>  Service["httpd"],
}

我去撞墙了……之前写成file当然没用了，后来又去掉了，这就是不认真看官方文档的下场……
