nginx安装ssl证书
nginx安装ssl证书
SSL证书是一种用于保护网站和用户数据的加密协议。在进行网上交易和数据传输时SSL证书可以确保数据受到加密保护从而保护用户的个人信息。nginx作为一种高性能和可扩展的Web服务器可以支持安装SSL证书来保护网站数据。
准备工作
在安装SSL证书之前需要确保已经安装了nginx服务器、openssl库和已经申请了SSL证书。如果还没有申请SSL证书则需要根据网站需要向证书颁发机构申请证书。
安装SSL证书
首先我们需要将SSL证书和私钥文件放到服务器的指定位置。一般来说SSL证书保存在/etc/nginx/ssl/目录下。将证书文件上传到服务器：
```
scp /path/to/certificate.crt user@server:/etc/nginx/ssl/
```
同样地将私钥文件上传到服务器：
```
scp /path/to/privatekey.key user@server:/etc/nginx/ssl/
```
然后在nginx配置文件中加入以下代码来启用SSL：
```
server {
listen 443 ssl;
server_name www.example.com;
ssl_certificate /etc/nginx/ssl/certificate.crt;
ssl_certificate_key /etc/nginx/ssl/privatekey.key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
}
```
这里的listen指令指定了监听SSL请求的端口是443同时通过ssl开启了SSL支持。ssl_certificate指令指定了我们刚才上传到服务器的SSL证书。同样地ssl_certificate_key指令指定了私钥文件的路径。
重启nginx服务器
完成上述配置之后需要重新启动nginx服务器以使更改生效。
```
sudo service nginx restart
```
验证证书是否生效
最后我们需要验证SSL证书是否已成功安装并生效。最简单的方法是在浏览器中打开您的网站并查看地址栏中的“锁”图标。
Install SSL Certificate for Nginx
SSL certificate is an encryption protocol used for protecting website and user data. It ensures that data is secured by encryption during online transactions and data transfers, thus safeguarding personal information of users. Nginx is a high-performance and scalable web server that supports installation of SSL certificate for securing website data.
Prerequisites:
Before installing the SSL certificate, ensure that nginx server, openssl library, and SSL certificate has been obtained. If SSL certificate hasn’t been obtained, get one from certificate authority as per website requirements.
Install SSL Certificate:
Firstly, we need to place SSL certificate and private key file under the designated location on server. Usually, we save SSL certificate under /etc/nginx/ssl/ directory in server. Below is the command for uploading the certificate file to the server:
```
scp /path/to/certificate.crt user@server:/etc/nginx/ssl/
```
Similarly, upload the private key file to the server:
```
scp /path/to/privatekey.key user@server:/etc/nginx/ssl/
```
Then, add the following code in nginx configuration file to enable SSL:
```
server {
listen 443 ssl;
server_name www.example.com;
ssl_certificate /etc/nginx/ssl/certificate.crt;
ssl_certificate_key /etc/nginx/ssl/privatekey.key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
}
```
The listen instruction specifies the port on which SSL requests are to be listened at port 443, and SSL support is enabled through ssl. The ssl_certificate specifying the SSL certificate previously uploaded on server. Similarly, ssl_certificate_key specifies the path to private key file.
Restart Nginx Server:
After the above changes, restart the nginx server to apply the changes.
```
sudo service nginx restart
```
Verify SSL Certificate:
Finally, verify that SSL certificate has been successfully installed and working. The easiest way to do this is simply to open your website in your browser and check for “lock” symbol in the address bar.
