一、Tomcat + Nginx域名配置方法

如何通过nginx代理的方式进行域名访问

找到nginx/conf/nginx.conf，做如下关键配置：

upstream xx\{ \#配置upstream节点，这里节点名为“xx”  
server 116.255.111.111:8080;  
\}  
server\{  
listen 80;  
server\_name www.xxx.xx; \#这里配置nginx需要代理的域名  
location / \{  
proxy\_pass http://xx; \#指定反向代理为上面配置的那个upstream节点“xx”  
proxy\_set\_header Host $http\_host;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
\}  
\}

修改tomcat server.xml文件  
  
<Host name="xxx.xxx.xxx" appBase="webapps" unpackWARs="true" autoDeploy="true">  
<Context path="" docBase="/home/web/xxx" reloadable="true" crossContext="true" />  
</Host>

注意红色字体部分要注意 name为你的域名 path要为空否者无法访问到这个项目

二、Tomcat解析域名

将Tomcat的server.xml的服务端口默认为8080改为80（这样访问时就不用输入端口了）：

更改 server.xml中Host的名称为自己的域名

Tomcat+Nginx解析域名

通过nginx代理的方式进行域名访问，找到nginx/conf/nginx.conf，做如下关键配置：

upstream xx\{ \#配置upstream节点，这里节点名为“xx”

server 127.0.0.1:8080;

server\{

listen 80;

server\_name www.xxx.xx; \#这里配置nginx需要代理的域名

location / \{

proxy\_pass http://xx; \#指定反向代理为上面配置的那个upstream节点“xx”

proxy\_set\_header Host $http\_host;

proxy\_set\_header X-Real-IP $remote\_addr;

proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;

三、nginx+tomcat单个域名及多个域名配置

nginx做负载均衡的优势网上有很多介绍资料，这里我不再多做介绍。因为有很多系统要部署，涉及到域名、二级域名、多个域名等的部署。在实际的部署由于对nginx的不够熟悉，遇到过很多坑，其中这种多域名的配置，xxxx.com转发到www.xxxx.com、访问域名转发到tomcat里的项目等，现在先总结一部坑的解决办法。

如将xxxx.com这个域名指向8082端口里的tomcat项目，在做这个介绍前先讲个插曲，如访问xxxx.com需转向到www.xxxx.com，这一点很多人都会忽略。

现在如果要部署中台、后台、金融系统，找到nginx/conf/nginx.conf，修改配置：

upstream web{
      server localhost:8082;
    }
    upstream admin{
      server localhost:8083;
    }
    upstream finance{
      server localhost:8084;
    }
    server {
      listen    80;
      server_name finance.xxxx.com;
      #charset koi8-r;
      #access_log logs/host.access.log main;
      location / {
        proxy_pass http://finance;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
      #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;
      }
    }
    server {
      listen    80;
      server_name www.xxx.com;
      #charset koi8-r;
      #access_log logs/host.access.log main;
      location / {
        proxy_pass http://web;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
      #error_page 404       /404.html;
      # redirect server error pages to the static page /50x.html
      #
      error_page  500 502 503 504 /50x.html;
      location = /50x.html {
        root  html;
      }
      # proxy the PHP scripts to Apache listening on 127.0.0.1:80
      #
      #location ~ \.php$ {
      #  proxy_pass  http://127.0.0.1;
      #}
      # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
      #
      #location ~ \.php$ {
      #  root      html;
      #  fastcgi_pass  127.0.0.1:9000;
      #  fastcgi_index index.php;
      #  fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
      #  include    fastcgi_params;
      #}
      # deny access to .htaccess files, if Apache's document root
      # concurs with nginx's one
      #
      #location ~ /\.ht {
      #  deny all;
      #}
    }
    server {
      server_name xxxx.com;
      rewrite ^(.*) http://www.xxxx.com$1 permanent;
    }
    server {
      listen    80;
      server_name admin.xxxx.com;
      #charset koi8-r;
      #access_log logs/host.access.log main;
      location / {
        proxy_pass http://admin;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
      #error_page 404       /404.html;
      # redirect server error pages to the static page /50x.html
      #
      error_page  500 502 503 504 /50x.html;
      location = /50x.html {
        root  html;
      }
      # proxy the PHP scripts to Apache listening on 127.0.0.1:80
      #
      #location ~ \.php$ {
      #  proxy_pass  http://127.0.0.1;
      #}
      # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
      #
      #location ~ \.php$ {
      #  root      html;
      #  fastcgi_pass  127.0.0.1:9000;
      #  fastcgi_index index.php;
      #  fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
      #  include    fastcgi_params;
      #}
      # deny access to .htaccess files, if Apache's document root
      # concurs with nginx's one
      #
      #location ~ /\.ht {
      #  deny all;
      #}
    }

上面的配置还包括了访问xxxx.com转向www.xxxx.com的配置，如下：

server {
       server_name xxxx.com;
       rewrite ^(.*) http://www.xxxx.com$1 permanent;
     }

nginx的基本配置大致就是这样，如果绑定多个域名（不管是一级域名还是二级域名），需配置多个server，你会发现这几个server配置都差不多，主要是更改server\_name及proxy\_pass指向即可。upstream节点其实就是代理服务的访问路径。

如果此时访问域名，你会发现nginx的配置生效了，只是目前显示的是tomcat的默认界面。nginx的配置基本就这样了，接下来对tomcat做些配置的修改。找到tomcat里的conf/server.xml，注释掉默认的Host配置，添加如下Host配置：

以上是windows服务器下的配置，如为linux，只需更改appBase和docBase，指向项目的路径。tomcat的配置也已经完成，重启tomcat，访问域名就指向了tomcat里的项目。

<Host name="localhost" appBase="E:\\tomcat\\apache-tomcat-8.0.35-8082\\webapps\\web" deployOnStartup ="false" autoDeploy="false" unpackWARs="true">  
<Context path="/" docBase="E:\\tomcat\\apache-tomcat-8.0.35-8082\\webapps\\web" />

directory="logs" prefix="localhost\_access\_log" suffix=".txt"  
pattern="%h %l %u %t "%r" %s %b" />  
</Host>

//Nginx同一个域名配置多个项目

1.nginx按不同的目录分发给不同的项目:  
server \{  
  
listen 80;

server\_name example.com;  
  
  
location ^~ /project1 \{  
  
proxy\_pass http://localhost:8081;  
  
proxy\_set\_header Host $host;

proxy\_set\_header X-Real-IP $remote\_addr;

proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
  
\}

location ^~ /project2 \{  
  
proxy\_pass http://localhost:8082;  
  
proxy\_set\_header Host $host;  
  
proxy\_set\_header X-Real-IP $remote\_addr;  
  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
  
\}  
  
  
location / \{  
  
proxy\_pass http://localhost:8080;

proxy\_set\_header Host $host;

proxy\_set\_header X-Real-IP $remote\_addr;

proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;

这里配置了三个项目：

http://example.com/project1路径分发到http://localhost:8081  
http://example.com/project2路径分发到http://localhost:8082

其他路径分发到http://localhost:8080

2.启用二级域名，不同的项目分配不同的二级域名

server \{  
  
listen 80;

server\_name example.com;

location / \{  
  
proxy\_pass http://localhost:8080;

proxy\_set\_header Host $host;

proxy\_set\_header X-Real-IP $remote\_addr;
