同一个服务器ip可以放2个网站吗,nginx实现同一台服务器配置两个网站

我在一台虚拟机上(同一个IP)搭建了LNMP环境，然后部署两个网站(两个域名)，分别时www.4spaces.org,www.weiyanzixun.com，域名解析正常，同时开启了https证书。现在的问题是我访问www.4spaces.org这个域名时，经常会跳转到www.weiyanzixun.com这个域名上，请问我的配置问题出在哪里？

环境：

nginx version: nginx/1.12.1

两个域名的nginx配置文件分别如下：

配置1：.4spaces.https.conf

server{

listen 80;

server_name 4spaces.org www.4spaces.org;

add_header Strict-Transport-Security max-age=15768000;

return 301 https://$server_name$request_uri;

}

server {

listen 443 ssl http2;

server_name 4spaces.org www.4spaces.org;

index index.php index.html index.htm;

root /usr/share/nginx/html;

add_header X-Frame-Options DENY;

add_header X-Content-Type-Options nosniff;

ssl_certificate /etc/letsencrypt/live/4spaces.org/fullchain.pem;

ssl_certificate_key /etc/letsencrypt/live/4spaces.org/privkey.pem;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;

ssl_prefer_server_ciphers on;

ssl_session_cache shared:SSL:10m;

ssl_session_timeout 60m;

location / {

try_files $uri $uri/ /index.php?$args;

}

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

include fastcgi_params;

}

}

配置2：weiyan.https.conf

server{

listen 80;

server_name weiyanzixun.com www.weiyanzixun.com;

#告诉浏览器有效期内只准用 https 访问

add_header Strict-Transport-Security max-age=15768000;

#永久重定向到 https 站点

return 301 https://$server_name$request_uri;

}

server {

listen 443 ssl http2;

server_name weiyanzixun.com www.weiyanzixun.com;

index index.php index.html index.htm;

root /usr/share/nginx/weiyanzixun;

add_header X-Frame-Options DENY;

add_header X-Content-Type-Options nosniff;

ssl_certificate /etc/letsencrypt/live/weiyanzixun.com/fullchain.pem;

ssl_certificate_key /etc/letsencrypt/live/weiyanzixun.com/privkey.pem;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;

ssl_prefer_server_ciphers on;

ssl_session_cache shared:SSL:10m;

ssl_session_timeout 60m;

location / {

try_files $uri $uri/ /index.php?$args; #修改内容

}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

#修改此处内容支持php

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

include fastcgi_params;

}

}

请哪位大神告诉我问题出在哪里，还有就是这个配置有那些地方可以进行优化的？
