AWS opsworks上的Chef 12脚本无法安装jenkins

Question

我有以下厨师12脚本，我正在aws opsworks上运行以安装jenkins。 我从以下站点获得它： https : //wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu当我运行它时，它失败并显示以下错误：

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图像上运行执行配方时，出现以下错误

Setting up jenkins (2.32.1) ...
* Starting Jenkins Continuous Integration Server jenkins
...fail!
Setting up libnss3-nssdb (2:3.26.2-0ubuntu0.14.04.3) ...

和

我不确定詹金斯为什么无法开始。 当我在同一实例上运行两次配方时，它第二次成功。 非常感谢您的帮助，因为这是我的第一个Chef脚本。

Answer 1

事实证明答案在Chef stacktrace文件中。 apt-get进程运行两次，并且在安装软件包步骤中无法访问dpkg中的锁定文件。 更改

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


package 'install Jenkins' do
    package_name "jenkins"
end

至

apt_update 'all platforms' do
    action :update
end

apt_package 'jenkins' do
  action :install
end

解决了这个问题。
