在资源package[nginx]上执行操作安装时出错

Question

我试图在ec2服务器上安装nginx，使用yum作为依赖项。

这就是我的nginx/食谱/default.rb的样子，

include_recipe "yum"

package "nginx" do 
version "1.6.2" 
action :install 
end

template "nginx.conf" do 
source "nginx.conf.erb" 
path "#{node['nginx']['dir']}/nginx.conf" 
action :create 
mode 0644 
end

template "default.conf" do 
source "default-site.erb" 
path "#{node['nginx']['dir']}/conf.d/default.conf" 
action :create 
mode 0644 
end

service "nginx" do 
supports :restart => :true 
action [:enable, :start] 
end

此外，我还在metadata.rb中添加了下面一行

depends "yum" 

在试图在客户端ec2服务器上运行以下命令时，

sudo chef-client

我得到以下错误：

[2014-12-15T01:38:31-05:00] WARN:

SSL validation of HTTPS requests is disabled. HTTPS connections are still
encrypted, but chef is not able to detect forged replies or man in the middle
attacks.

要解决此问题，请在配置文件中添加如下条目：

  # Verify all HTTPS connections (recommended)
  ssl_verify_mode :verify_peer

  # OR, Verify only connections to chef-server
  verify_api_cert true

若要检查SSL配置或故障排除错误，可以使用

knife ssl check命令如下：

knife ssl check -c /etc/chef/client.rb

Answer 1

根据这一行：

STDERR: yum-dump Repository Error: failure: repodata/repomd.xml from rhui-REGION-rhel-server-releases: [Errno 256] No more mirrors to try.

百胜在到达存储库时遇到了问题。看来yum配置是错的。您可以使用一个简单的yum install nginx进行测试，看看它是否真的是一个链接到厨师的问题(在本例中是更新问题)，或者是否只有您的系统没有在rhn中正确注册/配置。
