CFEngine 3新手在这里。
我想在Ubuntu系统上安装Oracle JDK,如何在CFEngine中编写脚本?
我可以使用webupd8team提供的PPA在Shell中执行以下操作:
add-apt-repository ppa:webupd8team/java
apt-get update
echo "Installing JDK 7..."
echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections
echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections
apt-get install -y oracle-java7-installer
在CFEngine中完全没有这样做。到目前为止,我有:
body common control {
inputs => { "$(sys.libdir)/stdlib.cf" };
bundlesequence => { "manage_properties",
"manage_jdk"};
}
bundle agent manage_properties {
vars:
"prop_pkgs" slist => {"python-software-properties", "software-properties-common"};
"cmds" slist => { "/usr/bin/add-apt-repository ppa:webupd8team/java",
"/bin/echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections",
"/bin/echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections",
"/usr/bin/apt-get update" };
methods:
"$(prop_pkgs)"
handle => "manage_properties",
comment => "Make sure required properties packages are installed",
usebundle => package_latest("$(prop_pkgs)");
commands:
"$(cmds)"
comment => "Firing preinstall commands for JDK";
}
bundle agent manage_jdk {
methods:
"JDK"
handle => "manage_jdk",
comment => "Make sure Java is installed",
usebundle => package_latest("oracle-java7-installer");
}
但是诺言失败,并出现以下错误:
2014-06-30T14:11:18+0000 error: /default/manage_jdk/methods/'JDK'/default/package_latest/packages/'oracle-java7-installer'[0]: Finished command related to promiser 'oracle-java7-installer' -- an error occurred, returned 100
2014-06-30T14:11:18+0000 error: /default/manage_jdk/methods/'JDK'/default/package_latest/packages/'oracle-java7-installer'[0]: Bulk package schedule execution failed somewhere - unknown outcome for 'oracle-java7-installer'
将不胜感激任何指针。谢谢
最佳答案
我在您的策略中看到的一件事是,您正在运行一些需要外壳程序的命令(您的管道命令),并且您的命令承诺不会包含在任何外壳程序中。commands: "/bin/echo 'Hello World' | grep Hello" contain => in_shell;
另外,您似乎对预命令的看法非常必要。 CFEngine通常每5分钟运行一次策略。我将更多地集中在必要时执行必要的操作,并尝试着重于状态而不是操作。
例如,您无条件运行apt-add-repository。考虑在什么条件下您实际需要执行命令。
