如何在CHEF中为我的配方为两个不同的配置文件创建模板? [英] How create a template to my recipe in CHEF for two different configuration files?
问题描述
我有两个不同的配置文件,分别是 Ganglia Monitoring 守护程序 gmond
。
I have two different configuration files, to Ganglia Monitoring daemon, gmond
.
第一个(此配置文件来自ganglia-gmond-3.17,来自 rpmforge
包):
The first (this configuration file came with ganglia-gmond-3.17, from rpmforge
package):
/* This configuration is as close to 2.5.x default behavior as possible
The values closely match ./gmond/metric.h definitions in 2.5.x */
globals {
daemonize = yes
setuid = yes
user = ganglia
debug_level = 0
max_udp_msg_len = 1472

cleanup_threshold = 300 /*secs */
gexec = no
send_metadata_interval = 30 /*secs */
}

* tag that will wrap all hosts collected by this instance.
*/

used to only support having a single channel */

an xml description of the state of the cluster */
tcp_accept_channel {

loaded. If the module has been statically linked with gmond, it does

使用融合我看到了差别不大,但是足以不使我的应用程序运行,所以这就是为什么我无法制作相同的 .conf
文件的原因。但是我可以为此使用模板。
但是我该怎么做呢?
因为不是每个文件的变量都不相同,而是添加/删除了一些行,所以这就是我的所在。
Using meld I saw that the difference aren't much, but enough to don't make my application to run, so that's why I can't make the same .conf
file. But I could use a template for this.
But how can I do that ?
Because it's not some variable that differs from one file to another, but adding/removing some lines, and that's where I stuck.
任何想法,建议吗?

让我们从diff开始:
Let's start with diff:

所以 gmond.conf.erb
模板可能就是这样(缺少等式
文件的一部分):
So gmond.conf.erb
template could be something like that (missing the equal parts of the
files):
cluster {
name = "<%=@cluster[:name]%>"
owner = "Valter"
latlong = "unspecified"
url = ""
}
/* The host section describes attributes of the host, like the location */
host {
location = "unspecified"

}
/* You can specify as many tcp_accept_channels as you like to share
an xml description of the state of the cluster */
tcp_accept_channel {
port = <%=@tcp_accept_channel[:port]%>
}
可以这样称呼
template "/etc/whatever/gmond.conf" do
source "gmond.conf.erb"

group "root"
