环境 阿里的ECS

注意在安全组开启相应端口

两个站点 a.exemple.cn    b.exemple.cn

nginx配置文件和SLB不能同时都加载证书

如果两个站点是同一个根域名，则只在A站点配置文件中加入SSL，B站点即使不加入SSL配置也是可以的

SLB挂载网站是按照后端ECS服务器上配置网站的域名来计算的，如果后端ECS上有两个根域名的网站比如 a.exemple-A.cn    b.exemple-B.cn，则需要购买两个SLB实例

1、nginx加载https证书、SLB使用TCP模式监听端口

站点A

server {
listen 80;
server_name a.exemple.cn;
rewrite ^(.*)$ https://$host$1 permanent;
location / {
index index.html index.htm Agreement.html Privacy.html;
}
}
server {
listen 443 ;
server_name a.exemple.cn;
ssl on;
root /home/web/111/;
index index.html index.htm Agreement.html Privacy.html;
ssl_certificate /home/web/ssl/xxxxx.pem;
ssl_certificate_key /home/web/xxxxx.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/a.exemple.cn.access.log main;
error_log /var/log/nginx/a.exemple.cn.error.log;
location / {
root /home/web/111;
index index.html index.htm Agreement.html Privacy.html;
}
}

 

B站点

server {
 listen 80;
 server_name b.exemple.cn; 
rewrite ^(.*)$ https://$host$1 permanent;
 location / {
index index.html index.htm Agreement.html Privacy.html;
}
}
server {
 listen 443 ;
 server_name b.exemple.cn;
 ssl on;
 root /home/web/222;
 index index.html index.htm Agreement.html Privacy.html;
 ssl_certificate   /home/web/ssl/xxxxx.pem;
 ssl_certificate_key  /home/web/xxxxx.key;
 ssl_session_timeout 5m;
 ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
 ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
 ssl_prefer_server_ciphers on;
 access_log /var/log/nginx/b.exemple.cn.access.log main;
 error_log /var/log/nginx/b.exemple.cn.error.log;
 location / {
     root /home/web/222;
     index index.html index.htm Agreement.html Privacy.html;
 }
}

 2、nginx配置文件不加载ssl证书，SLB使用http和https模式监听端口

a站点

server {
 listen 80;
 server_name a.exemple.cn; 
 root /home/web/111;
 location / {
             rewrite ^(.*)$ https://$host$1 permanent;
}
}
server {
 listen 443 ;
 server_name a.exemple.cn;
 access_log /var/log/nginx/a.exemple.cn.access.log main;
 error_log /var/log/nginx/a.exemple.cn.error.log;
 location / {
     root /home/web/111;
     index index.html index.htm Agreement.html Privacy.html;
 }
}

b站点

server {
 listen 80;
 server_name b.exemple.cn; 
 root /home/web/222;
 location / {
             rewrite ^(.*)$ https://$host$1 permanent;
}
}
server {
 listen 443 ;
 server_name a.exemple.cn;
 access_log /var/log/nginx/b.exemple.cn.access.log main;
 error_log /var/log/nginx/b.exemple.cn.error.log;
 location / {
     root /home/web/222;
     index index.html index.htm Agreement.html Privacy.html;
 }
}
