nginx与tomcat进行结合：

nginx：192.168.223.136，tomcat：192.168.223.146

server {
　　listen 80;
　　server_name 192.168.223.136;

　　location / {

　　　　root html;
　　　　index index.html index.htm;
　　　　proxy_pass http://192.168.223.146:8080;
　　}

nginx日志如下：

192.168.223.1 - - [09/Aug/2017:13:43:26 +0800] "GET /myapp/login.jsp HTTP/1.1" 200 112 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" "-"
192.168.223.1 - - [09/Aug/2017:13:43:30 +0800] "GET / HTTP/1.1" 200 107 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" "-"
192.168.223.1 - - [09/Aug/2017:13:46:11 +0800] "GET /myapp/login.jsp HTTP/1.1" 200 112 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" "-"

tomcat日志如下：

192.168.223.136 - - [09/Aug/2017:13:43:26 +0800] "GET /myapp/login.jsp HTTP/1.0" 200 127
192.168.223.136 - - [09/Aug/2017:13:43:30 +0800] "GET / HTTP/1.0" 200 122
192.168.223.136 - - [09/Aug/2017:13:46:11 +0800] "GET /myapp/login.jsp HTTP/1.0" 200 127

如何才能使tomcat抓捕到真实的客户端ip呢？

1、在nginx上设置：

　　proxy_set_header X-Forwarded-For $remote_addr;

2、然后在tomcat日志定义处添加首部信息：

　　pattern="%h %{X-Forwarded-For}i %l %u %t "%r" %s %b" />

然后tomcat访问日志：

192.168.223.136 192.168.223.1 - - [09/Aug/2017:13:55:03 +0800] "GET /myapp/login.jsp HTTP/1.0" 200 127
192.168.223.136 192.168.223.1 - - [09/Aug/2017:13:55:04 +0800] "GET /myapp/login.jsp HTTP/1.0" 200 127

nginx结合tomcat实现动静分离：

location ~* \.(jsp|do)$ {
　　proxy_pass http://192.168.223.146:8080;
}

访问网址：

默认首页是index.html所以访问的是nginx自己的html下的index.html

当后缀为jsp时，就请求访问tomcat了，在tomcat日志那里也可以查看：

192.168.223.136 - - - [09/Aug/2017:14:09:03 +0800] "GET /index.jsp HTTP/1.0" 200 122

利用nginx作为代理服务器，转向192.168.223.146的httpd服务器，然后通过httpd转向本地的tomcat

nginx：192.168.223.136   httpd：192.168.223.146，版本2.4以上  tomcat：192.168.223.146

配置httpd：同以上

　　1、在主配置文件httpd.conf开启下面两个模块：

　　LoadModule proxy_module modules/mod_proxy.so

　　LoadModule proxy_http_module modules/mod_proxy_http.so

　　2、开启后打开虚拟主机的支持文件：

　　# Virtual hosts

　　Include /etc/httpd2.4/extra/httpd-vhosts.conf

　　3、然后编辑vhosts文件：

　　

　　　　ServerName 192.168.223.146            httpd和tomcat位于同一主机

　　　　proxyVia On                     

　　　　ProxyRequests Off           

　　　　ProxyPreserveHost On      

　　　　        

　　　　　　Require all granted

　　　　

　　　　ProxyPass / http://192.168.223.146:8080/           

　　　　ProxyPassReverse / http://192.168.223.146:8080/

　　　　

　　　　　　Require all granted

　　　　

　　

http日志：

192.168.223.136 - - [09/Aug/2017:14:37:09 +0800] "GET /index.jsp HTTP/1.0" 200 122

tomcat日志：

192.168.223.146 192.168.223.136 - - [09/Aug/2017:14:37:09 +0800] "GET /index.jsp HTTP/1.1" 200 122

nginx只是做反代，没有处理请求的义务，由于后端httpd是直接反带的所以httpd默认的html下面的index.html不是tomcatwebapps下面的index.html

在tomcat的应用目录/data/webapps/ROOT下面创建一个index.html

cp index.html /data/webapps/ROOT/，然后再次访问：

查看httpd日志：

192.168.223.136 - - [09/Aug/2017:14:41:41 +0800] "GET /index.html HTTP/1.0" 200 45

查看你tomcat日志：

192.168.223.146 192.168.223.136 - - [09/Aug/2017:14:41:41 +0800] "GET /index.html HTTP/1.1" 200 45
