nginx配置tomcat与配置rewrite。

  tomcat的server.xml文件下可以配置<Context path > docBase 配置项目的访问路径，这样可以直接访问tomcat的端口不用加项目名称来访问项目。

 

<Context path="" docBase="/usr/project/XYD" reloadable="true">
</Context>

 

 

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

<Context path="" docBase="/usr/project/XYD" reloadable="true">
</Context>

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->

      </Host>

 

nginx proxy_pass实现项目upstream负载：

 

upstream hostname{
server 127.0.0.1:8080  max_fails=0 weight=1;
server 127.0.0.1:8090 max_fails=0 weight=1;
server 192.168.5.82:8080 max_fails=0 weight=1;
}
server {
    listen       80;
    server_name  _;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        proxy_pass  http://hostname;
        proxy_set_header X-Real-IP $remote_addr;
        #root   /usr/share/nginx/html;
       #index  index.html index.htm;
        # example
        #ModSecurityEnabled on;
        #ModSecurityConfig /etc/nginx/modsecurity.conf;

       #rewrite ^/ http://192.168.5.31:8080/XYD;

    }

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/html;
    }

 

----rewrite的解释

  #rewrite ^/ http://192.168.5.31:8080/XYD;   配置后 访问 localhost后项目直接跳转到相应的域名项目目录。
