Nginx+Tomcat实现单IP、多域名、多站点的访问

最近帮朋友做了两个网站，预算很小很小.小到两个网站只能跑在一台512M内存的公网服务器上(tomcat+MySQL,由于内存太小了，只能把两个网站部署在同一个tomcat上)，每个网站有自己的域名，初步考虑使有nginx做反向代理，把两个域名映射到相应的应用上。因此就有了标题所说的“nginx多域名单服务器单IP单Tomcat不同应用”上的配置问题。Nginx介绍的废话就不多说了，在这里把配置文件贴出来给大家参考一下吧：

域名A：www.a.com的配置文件如下：

[plain] view plain copy print?



server {
listen 80;
server_name *.a.com;
location / {
proxy_pass http://localhost:8080/projectA/; proxy_set_header Host host;  </span></li><li class="alt"><span>        proxy_set_header   X-Real-IP   remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

server {
listen       80;
server_name  *.a.com;
location / {
proxy_pass http://localhost:8080/projectA/; proxy_set_header   Host    $host;
proxy_set_header   X-Real-IP   $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

域名B：www.b.com的配置文件如下：

[plain] view plain copy print?



server {
listen 80;
server_name *.b.com;
location / {
proxy_pass http://localhost:8080/projectB/; proxy_set_header Host host;  </span></li><li class="alt"><span>        proxy_set_header   X-Real-IP   remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

server {
listen       80;
server_name  *.b.com;
location / {
proxy_pass http://localhost:8080/projectB/; proxy_set_header   Host    $host;
proxy_set_header   X-Real-IP   $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
