我已经写了下面的代码，如果交换不到位，这工作正常，但一旦交换被创build，如果脚本再次执行，它会导致错误。
我尝试使用onlyif添加条件，除非在下面的代码中注释，但他们似乎没有任何工作
class swap { exec { "create swap file": command => "dd if=/dev/zero of=/swapfile bs=1M count=1024", path => "/bin/", creates => "/swapfile", } exec { "makeswap": command => "mkswap /swapfile", path => "/sbin/", # condition so that the block is executed only if the swap is not place onlyif => "/sbin/swapon -s | /bin/grep file > /dev/null", require => Exec['create swap file'], } exec { "enable swap": command => "swapon /swapfile", path => "/sbin/", require => Exec['makeswap'], } } include swap 下面是控制台logindebugging

这个问题已经通过在下面的声明中解决了
除非=>“/ sbin / swapon -s | / bin / grep文件> / dev / null”
