+title: '更换SSL证书的方法'
+---
+
+## 背景说明
+
+- 网站通过NGINX代理
+- NGINX通过Docker部署
+- 域名通过阿里云购入
+- SSL证书通过阿里云申请
+
+## 更换方法
+
+基于上面的背景，更换SSL证书共分为四步：
+
+1. 申请新的SSL证书
+
+    ![alt text](image.png)
+
+    点击```创建证书```，在弹出的页面中，输入```域名名称```，然后点击```提交审核```。等待大概10分钟，就会通过审核并完成证书签发，这个过程无需做任何操作，因为域名和SSL证书都是通过阿里云，所以会自动添加记录值和验证。
+
+2. 下载证书
+
+    ![alt text](image-1.png)
+
+    服务器类型为Nginx，点击下载。解压之后，可以得到```.key```和```.pem```文件。
+
+3. 配置新的SSL证书
+
+    把```.key```和```.pem```文件放在```cert/```目录下（替换原来的证书文件）。
+
+4. 重启NGINX服务
+
+    ```bash
+    docker restart nginx
+    ```
+
+至此，SSL证书更换完成。
+
+## 后记
+
+如果是首次配置SSL证书，还需要在nginx的配置文件中添加如下内容：
+
+```nginx
+server
+{
+    listen 443 ssl;
+    server_name [your domain name];
+
+    ssl_certificate cert/1970666.xyz.pem;
+    ssl_certificate_key cert/1970666.xyz.key;
+
+    ssl_session_cache shared:SSL:1m;
+    ssl_session_timeout  5m;
+
+    location / {
+        root /usr/share/nginx/html/blog;
+        index index.html;
+        try_files $uri $uri/ =404;
+    }
+
+     access_log /logs/blog.log;
+}
+
+server {
+    listen 80;
+    server_name [your domain name];
+    
+    rewrite ^(.*)$ https://$host$1;
+    location / {
+        index index.html index.htm;
+    }
+}
+```
