NT的实现
yum -y install nginx 安装Nginx
cd /etc/nginx/conf.d/
vim tomcat.conf
server {
listen 80;
server_name www.chenxi.com;
location / {
proxy_pass http://127.0.0.1; 定义只要非.jsp与do文件结尾的都访问本机，也就是动静分离
}
location ~* \.(jsp|do)$ {
proxy_pass http://www.chenxis.com:8080;
}
}
server {
listen 80;
server_name www.chenxit.com;
location / {
proxy_pass http://www.chenxid.com:8080;
}
}
getenforce 查看SELinux策略
setenforce 0 关闭SELinux策略

[root@localhost conf.d]# vim tomcat-http.conf
<VirtualHost *:80>
ServerName www.chenxi.com
ServerAlias www.cx.com 定义一个别名
ProxyRequests Off 是否关闭正想代理off关闭
ProxyVia On响应是是否加一个手部
ProxyPreserveHost Off 是否将客户端请求主机名传递后端主机on传递off不传递
<Proxy *>
Require all granted对本地所有代理功能都允许
</Proxy>
ProxyPass / http://www.chenxis.com:8080/表示你请求的内容是什么后面内容就是什么；建议一致，不一致重写是会出问题
ProxyPassReverse / http://www.chenxis.com:8080/ 重写后是否对新URL做代理
<Location />
Require all granted做授权2.4要求必须要授权的
</Location>
</VirtualHost>
客户端的host文件

使用ajp协议实现at

实现NAT用jsp
[root@localhost yum.repos.d]# yum -y install nginx
[root@localhost conf.d]# cd /etc/nginx/conf.d/
[root@localhost conf.d]# cat tomcat.conf Nginx的相关设定
server {
listen 80;
server_name www.chenxi.com;
location / {
proxy_pass http://127.0.0.1;
}
location ~* \.(jsp|do)$ {
proxy_pass http://www.chenxis.com:8080;
}
}
server {
listen 80;
server_name www.chenxit.com;
location / {
proxy_pass http://www.chenxid.com:8080;
}
}
[root@localhost conf.d]# vim tomcat-http.conf httpd端使用ajp代理
<VirtualHost *:80>
ServerName www.chenxi.com
ServerAlias www.cx.com
ProxyRequests Off 关闭正向代理
ProxyVia On
ProxyPreserveHost Off
<Proxy *>
Require all granted
</Proxy>
ProxyPass / ajp:/ http.chenxis.com:8009/
ProxyPassReverse / http://www.chenxis.com:8009/

实现NAT用httd的配置
http的相关配置
[root@localhost httpd]# vim /etc/httpd/conf.d/tomcat-http.conf
<VirtualHost *:80>
ServerName www.chenxi.com
ServerAlias www.cx.com
ProxyRequests Off
ProxyVia On
ProxyPreserveHost Off
<Proxy *>

ProxyPass / http://www.chenxis.com:8080/
ProxyPassReverse / http://www.chenxis.com:8080/
