nginx简单实现*和静态资源服务器

1修改hosts文件

127.0.0.1    www.test1.com
127.0.0.1    www.test2.com
127.0.0.1    static.com

2配置tomcat的server.xml

<?xml version='1.0' encoding='utf-8'?>

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

 
  <GlobalNamingResources>
   
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  
  <Service name="Catalina">

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>
      
       <Host name="www.test1.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

        <Context path ="" docBase ="/test1" debug ="0" reloadbale ="true" ></Context>

      </Host>
      
      <Host name="www.test2.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

        <Context path ="" docBase ="/test2" debug ="0" reloadbale ="true" ></Context>

      </Host>
    </Engine>
  </Service>
</Server>

将test1和test2项目放在tomcat根目录/webapps下（项目用war包或者war解压后的目录文件都行）

3配置nginx的nginx.conf文件

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #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;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
    
    upstream Tomcat_client {
       server localhost:8080;
    }
     server {
        listen 80;
        server_name www.test1.com;
        
        location / {
            proxy_pass http://Tomcat_client;
            proxy_redirect default;
            #设置代理
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }
    }
    
    server {
        listen 80;
        server_name www.test2.com;
        location / {
            proxy_pass http://Tomcat_client;
            proxy_redirect default;
            #设置代理
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }
    }
    
    server {
        listen 80;
        server_name static.com;
        
        location / {
            root   C:/image;
            autoindex on;
            
        }
    }

}

主要关注116~153行；启动toncat和nginx，在C盘下建image文件，可通过http://static.com/直接访问静态资源。也可在其他html页面访问静态资源

浏览器输入www.test1.com回车，因为http默认端口为80，所以相当于输入的是www.test1.com:80 而nginx监听了80端口，找到server_name为www.test1.com的server，然后将请求交给被代理的tomcat服务器，如136行所示，Tomcat_client实际上表示localhost:8080
