nginx整合tomcat实现域名泛解析

摘要: nginx整合tomcat实现域名泛解析

一、下载安装tomcat

1、解压

[root@iZ28zo01ceuZ bin]# mkdir /usr/local/tomcat

[root@iZ28zo01ceuZ bin]# cd /usr/local/tomcat

[root@iZ28zo01ceuZ bin]# tar -zxvf /software/apache-tomcat-7.0.54.tar.gz

2、在控制台输入

[root@iZ28zo01ceuZ bin]#cd /usr/local/tomcat/bin/

[root@iZ28zo01ceuZ bin]#vim catalina.sh

在编辑里面加入

ATALINA_HOME=/usr/tomcat/

3、启动

[root@iZ28zo01ceuZ bin]# ./startup.sh

4、启动成功提示：

Using CATALINA_BASE: /var/tomcat/tomcatyey
Using CATALINA_HOME: /var/tomcat/tomcatyey
Using CATALINA_TMPDIR: /var/tomcat/tomcatyey/temp
Using JRE_HOME: /usr/lib/jvm/jre-1.8.0-openjdk
Using CLASSPATH: /var/tomcat/tomcatyey/bin/bootstrap.jar:/var/tomcat/tomcatyey/bin/tomcat-juli.jar
Tomcat started.
其中查找对应tomcat进程查找：

[root@iZ28zo01ceuZ bin]# ps -ef |grep tomcat

找到对应的pid即可操作Kill

[root@iZ28zo01ceuZ bin]# kill pid -9

5、部署web项目到tomcat中

二、nginx配置：

server
{
listen 80;
server_name *.beizhiyuan.com.cn; #绑定域名
location / {
proxy_pass http://127.0.0.1:8086;

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

}

/usr/local/nginx/sbin/nginx -s reload

nginx已经重启成功

可以访问了。如：http://lmjxxfsyey.beizhiyuan.com.cn/ 就是使用此方法部署的，在后台判断host来获取对应域名所对应的数据。

@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
final HttpServletRequest req = (HttpServletRequest) request;
final HttpServletResponse res = (HttpServletResponse) response;
String requestPage =req.getHeader("Host");

if (req.getRequestURL().indexOf("http://app.beizhiyuan.com.cn") < 0
&& req.getRequestURL().indexOf("http://shop.beizhiyuan.com.cn") < 0
&&req.getRequestURL().indexOf("http://www.beizhiyuan.com.cn") < 0
&&req.getRequestURL().indexOf("http://beizhiyuan.com.cn")<0) {
int endIndex = requestPage.indexOf(".");
String secondDomainName = requestPage.substring(0, endIndex);
req.getSession().setAttribute("schoolurl",secondDomainName);
}
chain.doFilter(request, response);
}
