木偶。使用带有 2 个变量的定义
Puppet. Using define with 2 variables
我有配置文件 /home/ipeacocks/Dropbox/nscd/nscd.conf:
$ cat home/ipeacocks/Dropbox/nscd/nscd.conf
logfile /var/log/nscd.log
threads 4
max-threads 32
server-user nobody
stat-user somebody
debug-level 0
reload-count 5
paranoia no
restart-interval 3600
使用木偶我想改变 2 行:
server-user nobody
paranoia no
到这些行:
server-user nscd
paranoia yes
因此,为了更改第一行,我可以使用这样的清单:
include nscd
class nscd {
define line_replace ($line, $match) {
file_line {'some useful info':
path => '/home/ipeacocks/Dropbox/nscd/nscd.conf',
line => $line,
match => $match
}
}
anchor{'nscd::begin':}
->
package { 'nscd':
ensure => installed,
}
->
line_replace {'test':
line => "server-user nscd",
match => "^\s*server-user.*$"
}
->
service { 'nscd':
ensure => running,
enable => "true",
}
->
anchor{'nscd::end':}
}
人偶发射:

但是当 2 行时不能(使用声明的函数两次):
include nscd
class nscd {
define line_replace ($line, $match) {
file_line {'some useful info':
path => '/home/ipeacocks/Dropbox/nscd/nscd.conf',
line => $line,
match => $match
}
}
anchor{'nscd::begin':}
->
package { 'nscd':
ensure => installed,
}
->
line_replace {'test':
line => "server-user nscd",
match => "^\s*server-user.*$"
}
->
line_replace {'test2':
line => "paranoia yes",
match => "^\s*paranoia.*$"
}
->
service { 'nscd':
ensure => running,
enable => "true",
}
->
anchor{'nscd::end':}
}
再次启动:
» sudo puppet apply /home/ipeacocks/Dropbox/nscd/nscd.pp 1 ↵

有什么问题吗?是否可以一次将两对变量传递给声明的函数(使用数组或类似的)?
我试过这个解决方案,但它对我不起作用:
用这个替换你的定义:
define line_replace ($line, $match) {
file_line {$name:
path => '/home/ipeacocks/Dropbox/nscd/nscd.conf',
line => $line,
match => $match
}
}
我将 file_line 资源名称从常量更改为您定义的 $name 参数。
将 'some useful info' 更改为 file_line 中的 $name -
define line_replace ($line, $match) {
file_line {$name:
path => '/home/ipeacocks/Dropbox/nscd/nscd.conf',
line => $line,
match => $match
}
}
您面临的问题是因为对 line_replace 的第二次调用导致调用 file_line 并且资源名称 'some useful info' 已经声明。
