-## Prepare certs
+## 准备证书
 
-1. Make sure you can find the kubernetes `ca.crt` and `ca.key` files. If you set up your kubernetes cluster by `kubeadm` , those files will be in `/etc/kubernetes/pki/` dir.
+1. 请确保可以找到 `ca.crt` 和 `ca.key` 两个 Kubernetes 证书文件。 如果您使用 `kubeadm`进行 Kubernetes 集群安装，这两个文件将位于 `/etc/kubernetes/pki/` 路径下。
 
     ``` shell
     ls /etc/kubernetes/pki/
     ```
 
-2. Set `CLOUDCOREIPS` env. The environment variable is set to specify the IP address of cloudcore, or a VIP if you have a highly available cluster.
+2. 设置 `CLOUDCOREIPS` 变量。 这个环境变量设置为指定 cloudcore 的 IP 地址，如果您的集群是以高可用方式部署，请设置为分配给负载均衡器的虚拟 IP 地址。
 
     ```bash
     export CLOUDCOREIPS="192.168.0.139"
     ```
-    (Warning: the same **terminal** is essential to continue the work, or it is necessary to type this command again.) Checking the environment variable with the following command:
+    (注: 必须使用同一 **终端** 才能使设置生效， 如果更换了终端，必须再次执行该指令。)可以通过使用以下命令检查该环境变量：
     ``` shell
     echo $CLOUDCOREIPS
     ```
 
-3. Generate the certificates for **CloudStream** on cloud node, however, the generation file is not in the `/etc/kubeedge/`, we need to copy it from the repository which was git cloned from GitHub.
-   Change user to root:
+3. 接下来，需要给云节点上为 **CloudStream** 生成证书，然而，相关生成脚本不在 `/etc/kubeedge/` 中， 我们需要从 GitHub 的 git 仓库中获取。
+   改变权限至 root 权限：
     ```shell
     sudo su
     ```
-    Copy certificates generation file from original cloned repository:
+    从 git 仓库中 clone 证书生成文件：
     ```shell
     cp $GOPATH/src/github.com/kubeedge/kubeedge/build/tools/certgen.sh /etc/kubeedge/
     ```
-    Change directory to the kubeedge directory:
+    切换到 kubeedge 路径下：
     ```shell
     cd /etc/kubeedge/
     ```
-    Generate certificates from **certgen.sh**
+    使用 **certgen.sh** 生成证书：
     ```bash
     /etc/kubeedge/certgen.sh stream
     ```
 
-## Set Iptables Rule
+## 设置 Iptables 规则
 
-1. Set iptables on the host. This command should be executed on every node which deployed apiserver.(In this case, it is the master node, and execute this command by root.)
+1. 在主机上设置iptables。注意这个命令需要在部署了 apiserver 的每个节点上执行。（在本例中，是在主节点，运用通过 root 用户执行命令。）
 
-    Run the following command on the host on which each apiserver runs:
+    在每个运行有 apiserver 的主机上运行以下命令：
 
-    **Note:** You need to set the cloudcoreips variable first
+    **注:** 请先确保 CLOUDCOREIPS 环境变量设置正确
 
     ```bash
     iptables -t nat -A OUTPUT -p tcp --dport 10350 -j DNAT --to $CLOUDCOREIPS:10003
     ```
-    > Port 10003 and 10350 are the default ports for the CloudStream and edgecore,
-    use your own ports if you have changed them.
+    > 端口 10003 和 10350 是 CloudStream 和 edgecore 的默认端口，如果您对它们做过修改，请使用您设置的端口。
 
-    If you are not sure whether you have a setting of iptables, and you want to clean all of them.
-    (If you set up iptables wrongly, it will block you out of this feature)
+    如果您不确定是够有 iptables 设置，并且想清理所有 iptables。
+    (如果您设置了错误的 iptables，它会阻止您使用此功能)
 
-    The following command can be used to clean up iptables:
+    以下命令用于清除 iptables 规则:
     ``` shell
     iptables -F && iptables -t nat -F && iptables -t mangle -F && iptables -X
