linux-nginx反代理tomcat

利用 nginx 反向代理实现全部转发置指定同一个虚拟主 机

设别

centos7   10.0.0.17   tomcat多虚拟主机

centos7    10.0.0.27   nginx 代理

centos7     10.0.0.7     客户端

 

域名解析

10.0.0.27   nginx    配置hosts文件

10.0.0.17   www.lia.com www.lib.com  www.lic.com

10.0.0.7   客户端  访问  nginx代理服务器    配置hosts文件

10.0.0.27   www.lia.com www.lib.com  www.lic.com

 

创建多虚拟主机的文件的访问路径    10.0.0.17 tomcat 服务器

[root@centos7-liyj /usr/local/tomcat]#mkdir /data/webapps{1,2,3}      创建目录
[root@centos7-liyj /usr/local/tomcat]#mkdir /data/webapps{1,2,3}/ROOT 
[root@centos7-liyj /usr/local/tomcat]#cd
[root@centos7-liyj /data]#tree
.
├── webapps1
│   └── ROOT
├── webapps2
│   └── ROOT
└── webapps3
    └── ROOT

6 directories, 0 files
[root@centos7-liyj /data]#chown -R tomcat.tomcat /data/webapps1         #修改权限为tomcat
[root@centos7-liyj /data]#chown -R tomcat.tomcat /data/webapps2   
[root@centos7-liyj /data]#chown -R tomcat.tomcat /data/webapps3
[root@centos7-liyj /data]#echo www.lia.com > /data/webapps1/ROOT/index.html  #建立访问文件
[root@centos7-liyj /data]#echo www.lib.com > /data/webapps2/ROOT/index.html
[root@centos7-liyj /data]#echo www.lic.com > /data/webapps3/ROOT/index.html

 

修改tomcat配置文件

[root@centos7-liyj /usr/local/tomcat]#vim conf/server.xml 

      <Host name="localhost"  appBase="webapps"                       #复制此行修改
            unpackWARs="true" autoDeploy="true">

        <!-- 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
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"   #此处为日志信息，有需求也可复制
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>

      <Host name="www.lia.com"  appBase="/data/webapps1/"              #修改name为要访问的域名，appBase修改为域名访问的文件路径
            unpackWARs="true" autoDeploy="true">
      </Host>

      <Host name="www.lib.com"  appBase="/data/webapps2/"
            unpackWARs="true" autoDeploy="true">
      </Host>

      <Host name="www.lic.com"  appBase="/data/webapps3/"
            unpackWARs="true" autoDeploy="true">
      </Host>

 重启服务

[root@centos7-liyj /usr/local/tomcat]#systemctl restart tomcat

nginx代理服务器配置

[root@centos7-liyj ~]#vim /usr/local/nginx/conf/nginx.conf

           # root   html;
           # index  index.html index.htm;
            proxy_pass http://www.lia.com:8080;  #添加代理配置，指定域名
        }
