接上一篇 《Linux 安装Nginx (Nginx-1.25.4)》

本文描述如何配置Nginx多域名及SSL证书。

假设Nginx安装在/usr/local/nginx目录下。Nginx的配置文件为：/usr/local/nginx/conf/nginx.conf，要实现配置域名和SSL证书，都是修改此配置文件。

1.配置域名

通过server_name配置节点进行配置，如下所示：

server  
    {  
	    listen	80;  
         server_name	hellocode.net;           #绑定域名  
         index index.htm index.html index.php;   #默认文件  
         location / {
            root   html;
            index  index.html index.htm;
        } 
    }  

如果有多个域名，只需多配置几个server节点即可。

    server  
    {  
	    listen	80;  
         server_name	hellocode.net;         #绑定域名  
         index index.htm index.html index.php;   #默认文件  
         location / {
            root   html;
            index  index.html index.htm;
        } 
    }   
    server  
    {  
	    listen	80;  
         server_name	cnsites.com;         #绑定域名  
         index index.htm index.html index.php;   #默认文件  
         location / {
            root   html;
            index  index.html index.htm;
        } 
    }

2.绑定SSL证书

这里以阿里云免费SSL证书为例。

1.申请并下载证书。

先去阿里云申请免费SSL证书，并下载适用于Nginx的证书。

2.上传证书到服务器

在服务器上创建目录/usr/local/nginx/ssl，并将证书解压后，上传到此目录。

3.配置Nginx证书 

修改配置文件：/usr/local/nginx/conf/nginx.conf

以下是完整的nginx.conf文件，仅供参考。

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

    worker_connections  1024;

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;

    keepalive_timeout  65;

    #gzip  on;
    server  
    {  
	    listen	80;  
         server_name	hellocode.net;         #绑定域名  
         index index.htm index.html index.php;   #默认文件  
         location / {
            root   html;
            index  index.html index.htm;
        } 
    }   
    server  
    {  
	    listen	80;  
         server_name	cnsites.com;         #绑定域名  
         index index.htm index.html index.php;   #默认文件  
         location / {
            root   html;
            index  index.html index.htm;
        } 
    }
    server {
        listen      80;   
             
        listen 443 ssl;
        ssl_certificate ../ssl/qingshanboke.com.pem; 
        #需要将cert-file-name.pem替换成已上传的证书文件的名称。
    	   ssl_certificate_key ../ssl/qingshanboke.com.key;
    	   #需要将cert-file-name.key替换成已上传的证书密钥文件的名称。
        ssl_session_timeout 5m;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm;
        }
        #error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #

    # HTTPS server
    #
    #server {

    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

注意：修改配置后，都需重载Nginx，配置才会生效。

命令：/usr/local/nginx/sbin/nginx -s reload
