|
||
<p>执行下列步骤前建议你先阅读以下内容：</p>
|
||
<ul>
|
||
<li><a href="../guide/managing-tls-in-a-cluster.html">管理集群中的TLS</a>：教您如何创建TLS证书</li>
|
||
<li><a href="../guide/kubelet-authentication-authorization.html">kubelet的认证授权</a>：向您描述如何通过认证授权来访问 kubelet 的 HTTPS 端点。</li>
|
||
<li><a href="../guide/tls-bootstrapping.html">TLS bootstrap</a>：介绍如何为 kubelet 设置 TLS 客户端证书引导（bootstrap）。</li>
|
||
</ul>
|
||
<p><strong>注意：</strong>这一步是在安装配置kubernetes的所有步骤中最容易出错也最难于排查问题的一步，而这却刚好是第一步，万事开头难，不要因为这点困难就望而却步。</p>
|
||
<p><strong>如果您足够有信心在完全不了解自己在做什么的情况下能够成功地完成了这一步的配置，那么您可以尽管跳过上面的几篇文章直接进行下面的操作。</strong></p>
|
||
<p><code>kubernetes</code> 系统的各组件需要使用 <code>TLS</code> 证书对通信进行加密，本文档使用 <code>CloudFlare</code> 的 PKI 工具集 <a href="https://github.com/cloudflare/cfssl" target="_blank">cfssl</a> 来生成 Certificate Authority (CA) 和其它证书；</p>
|
||
<p><strong>生成的 CA 证书和秘钥文件如下：</strong></p>
|
||
<ul>
|
||
<li>ca-key.pem</li>
|
||
<li>ca.pem</li>
|
||
<li>kubernetes-key.pem</li>
|
||
<li>kubernetes.pem</li>
|
||
<li>kube-proxy.pem</li>
|
||
<li>kube-proxy-key.pem</li>
|
||
<li>admin.pem</li>
|
||
<li>admin-key.pem</li>
|
||
</ul>
|
||
<p><strong>使用证书的组件如下：</strong></p>
|
||
<ul>
|
||
<li>etcd：使用 ca.pem、kubernetes-key.pem、kubernetes.pem；</li>
|
||
<li>kube-apiserver：使用 ca.pem、kubernetes-key.pem、kubernetes.pem；</li>
|
||
<li>kubelet：使用 ca.pem；</li>
|
||
<li>kube-proxy：使用 ca.pem、kube-proxy-key.pem、kube-proxy.pem；</li>
|
||
<li>kubectl：使用 ca.pem、admin-key.pem、admin.pem；</li>
|
||
</ul>
|
||
<p><code>kube-controller</code>、<code>kube-scheduler</code> 当前需要和 <code>kube-apiserver</code> 部署在同一台机器上且使用非安全端口通信，故不需要证书。</p>
|
||
<p><strong>注意：以下操作都在 master 节点即 172.20.0.113 这台主机上执行，证书只需要创建一次即可，以后在向集群中添加新节点时只要将 /etc/kubernetes/ 目录下的证书拷贝到新节点上即可。</strong></p>

<h2 id="安装-cfssl">安装 <code>CFSSL</code></h2>
|
||
<p><strong>方式一：直接使用二进制源码包安装</strong></p>
|
||
<pre><code class="lang-bash">wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
|
||
chmod +x cfssl_linux-amd64
|
||
mv cfssl_linux-amd64 /root/<span class="hljs-built_in">local</span>/bin/cfssl
|
||
|
||
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
|
||
chmod +x cfssljson_linux-amd64
|
||
mv cfssljson_linux-amd64 /root/<span class="hljs-built_in">local</span>/bin/cfssljson
|
||
|
||
wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64
|
||
chmod +x cfssl-certinfo_linux-amd64
|
||
mv cfssl-certinfo_linux-amd64 /root/<span class="hljs-built_in">local</span>/bin/cfssl-certinfo
|
||
|
||
<span class="hljs-built_in">export</span> PATH=/root/<span class="hljs-built_in">local</span>/bin:<span class="hljs-variable">$PATH</span>
|
||
</code></pre>
|
||
<p><strong>方式二：使用go命令安装</strong></p>
|
||
<p>我们的系统中安装了Go1.7.5，使用以下命令安装更快捷：</p>
|
||
<pre><code class="lang-bash">$ go get -u github.com/cloudflare/cfssl/cmd/...
|
||
$ <span class="hljs-built_in">echo</span> <span class="hljs-variable">$GOPATH</span>
|
||
/usr/<span class="hljs-built_in">local</span>
|
||
<span class="hljs-variable">$ls</span> /usr/<span class="hljs-built_in">local</span>/bin/cfssl*
|
||
cfssl cfssl-bundle cfssl-certinfo cfssljson cfssl-newkey cfssl-scan
|
||
</code></pre>
|
||
<p>在<code>$GOPATH/bin</code>目录下得到以cfssl开头的几个命令。</p>
