新购买的服务器，配置了一下Nginx的ssl证书，具体如下

http {
   server{
		listen 443 ssl;
		server_name www.xxx.com;
		ssl_certificate /etc/certs/cert.pem;
		ssl_certificate_key /etc/certs/cert.key;
		ssl_session_timeout 5m;
		ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
		ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
		ssl_prefer_server_ciphers on;
		
		location /wxpay/ {
			proxy_set_header Host $host; 
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Forwarded-Port $server_port;
			proxy_pass http://127.0.0.1:8080/wxpay;
		}
	}
	
	server {
        listen       80;
        server_name  www.xxx.com;
		rewrite ^/(.*)$ https://www.xxx.com:443/$1 permanent;
    }
}

发现无法启动，报nginx:[emerg]unknown directive ssl错误。
出现这个问题是因为我编译的时候没有添加ssl模块，解决办法如下：
打开编译目录，假设是 /home/nginx-1.26.3

cd /home/nginx-1.26.3

添加ssl模块

./configure --with-http_ssl_module

# 编译安装包
make

然后把编译好的文件替换之前的，在此之前你可以先备份一下原来的文件

cp objs/nginx /usr/local/nginx/sbin/nginx

最后，查看一下是否安装成功

/usr/local/nginx/sbin/nginx -V

如果看到这样的结果就表示安装成功了

[root@launch-advisor-20180716 nginx]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.26.3
built by gcc 11.5.0 20240719 (Red Hat 11.5.0-5) (GCC) 
built with OpenSSL 3.2.2 4 Jun 2024
TLS SNI support enabled
configure arguments: --with-http_ssl_module
TLS SNI support enabled

说明SSL可用，再启动Nginx就正常了
