【问题描述】：

我有以下 chef 12 脚本，我在 aws opsworks 上运行它来安装 jenkins。我从以下站点获取它：https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu 当我运行它时，它失败并出现以下错误：

execute 'add jenkins source to apt' do
    command "wget -q -O - https://pkg.jenkins.io/debian/jenkins-ci.org.key | sudo apt-key add -"
end


file '/etc/apt/sources.list.d/jenkins.list' do
    content 'deb http://pkg.jenkins.io/debian-stable binary/'
end

execute 'update apt-get' do
    command 'apt-get update'
end


package 'install Jenkins' do
    package_name "jenkins"
end

package 'install nginx' do
    package_name 'nginx'
end

file '/etc/nginx/sites-enabled/default' do
    action :delete
end

cookbook_file '/etc/nginx/sites-available/jenkins' do
    source 'jenkins'
end

link '/etc/nginx/sites-enabled/jenkins' do
    to '/etc/nginx/sites-available/jenkins'
    link_type :symbolic
end

service 'nginx' do
    action :restart
end

service 'jenkins' do
    action :restart
end

当我在运行 ubuntu 14.04 的 c4.4xlarge 映像上运行执行配方时，我收到以下错误

Setting up jenkins (2.32.1) ...

...fail!

我不确定 jenkins 无法启动的原因。当我在同一个实例上运行两次配方时，它第二次成功。非常感谢任何帮助，因为这是我的第一个 Chef 脚本。

【问题讨论】：

Jenkins 安装有official cookbook。您是否尝试过查看 Jenkins 日志？ （通常是/var/log/jenkins）或apt-get -q -y install jenkins=2.32.1 的输出？

您的apt-get 失败。尝试自己运行它，看看会发生什么。

检查 jenkins 日志，这是失败的安装后脚本。根据this，它可能是 /tmp

的权限

如果它在第二次运行中可靠地成功，那么您的配方存在时间问题。在或有流程完成（下载或安装需求）或资源以您未预料到的顺序运行之前，某些事情就开始了。尝试确定您需要的资源是什么，并使用notifies 语句docs.chef.io/resource_common.html#notifications 控制时间。

【参考方案1】：

原来答案在厨师堆栈跟踪文件中。 apt-get 进程运行两次，在安装包步骤中无法访问 dpkg 中的锁定文件。改变

execute 'update apt-get' do
    command 'apt-get update'
end


package 'install Jenkins' do
    package_name "jenkins"
end

到

apt_update 'all platforms' do
    action :update
end

apt_package 'jenkins' do
  action :install
end

解决了这个问题。
