Nginx+Apache+Tomcat实现LANMT动静分离

Nginx+Apache+Tomcat实现LANMT动静分离

        

目的：

   本次实验主要目的为实现以Nginx作为反向代理，并实现分别访问动静态服务的效果。

 

拓扑结构：

         client 172.16.0.1 –> nginx webproxy1,IP:172.16.10.10 –> httpd+tomcat web1,IP: 172.16.100.101 –> DB: maridDB IP: 172.16.200.200

                                                 –> httpd   ,web2,IP: 172.16.100.102

                                                                                                      

                                                                                                      

具体实现：

##进行环境设置

[root@web1 apache]# chmod +x /etc/rc.d/init.d/httpd

[root@web1 apache]# chkconfig –add httpd

[root@web1 apache]# chkconfig httpd on

##启动服务

[root@web1 apache]# service httpd start

Starting httpd: AH00557: httpd: apr_sockaddr_info_get() failed for web1.test.net

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message

##检查验证                                                           [  OK  ]

[root@web1 apache]# ss -ntlp | grep httpd

LISTEN     0      128                      :::80                      :::*      users:(("httpd",53093,4),("httpd",53096,4),("httpd",53097,4),("httpd",53098,4))

[root@web1 apache]# curl http://172.16.100.101

<html><body><h1>It works!</h1></body></html>

[root@web1 apache]#

 

 

3.Web2配置

##安装httpd

[root@web2 setup]# yum install -y httpd

##构造web2网页

 

[root@web2 setup]# vim /var/www/html/index.html

<h1>web2 172.16.100.102</h1>

##启动服务

[root@web2 setup]# service httpd start

Starting httpd: httpd: apr_sockaddr_info_get() failed for web2.test.net

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

##检查验证                                                           [  OK  ]

[root@web2 setup]# ss -ntlp | grep httpd

LISTEN     0      128                      :::80                      :::*      users:(("httpd",7978,4),("httpd",7981,4),("httpd",7982,4),("httpd",7983,4),("httpd",7984,4),("httpd",7985,4),("httpd",7986,4),("httpd",7987,4),("httpd",7988,4))

##以上基础安装设置完毕，下面开始设置访问网页的动静分离

##首先设置172.16.100.101上的httpd反向代理tomcat服务

        

##配置反向代理

 httpd.conf

 

ServerName web1.test.net

##DocumentRoot "/usr/local/apache/htdocs"

 # Virtual hosts

 Include /etc/httpd/extra/httpd-vhosts.conf

 

##虚拟主机设置,所有请求反代到tomcat8080

 [root@web1 extra]# vim httpd-vhosts.conf

<VirtualHost *:80>

  ServerName web1.test.net

  ProxyVia On

  ProxyRequests Off

  ProxyPreserveHost On

  <Proxy *>

    Require all granted

  </Proxy>

    ProxyPass / http://172.16.100.101:8080/

    ProxyPassReverse / http://172.16.100.101:8080/

  <Location />

      Require all granted

  </Location>

</VirtualHost>

 

 

##配置webprox1上的nginx，将动态网页(这里是jsp，同理，还可以是php)的请求转发至web1(172.16.100.101)，将静态网页的请求转发至web2(172.16.100.102)

 location ~* \.jsp$ {

   proxy_pass http://172.16.100.101;

 }

 

 location / {

   proxy_pass http://172.16.100.102;

 }

 

 

至于jsp连接mysql数据库，则只需在tomcat的机器上安装上专门连接mysql的驱动，然后在jsp代码中创建连接即可，我这里就偷懒不做了，或者留到下次再一并实现。             

##测试

                  

##请注意看效果，第一张图访问的url是webprox1的IP地址，且是动态jsp网页，获得的网页内容则是后端web1 tomcat8080的。而第二张图片访问的url IP地址不变，同样是webproxy1，但网页是静态的html，获取到的网页内容也相应的变成了web2上httpd的网页内容。因而，网站的动静态网页实现了分流。

本次实验只是简单的实现了LNAMT的反向代理及动静分离，并未涉及高可用和负载均衡。下次会将这两个元素添加进去，使整个环境与生产环境更为接近。敬请期待！

 

以上为我实现的LNAMT环境，我对linux的认识还是很肤浅，以上可能有不正确的地方，如有错漏，希望各位能指正，共同进步。
