一、编译安装nginx
请跳转查阅:编译安装nginx
二、tomcat的二进制安装
请跳转查阅:二进制安装tomcat
三、配置nginx代理
# cat /apps/nginx/conf/nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream tomcat-hosts {
server 10.0.0.18:8080;
server 10.0.0.28:8080;
}
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location ~* \.(jsp|do)$ {
proxy_pass http://tomcat-server;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
四、配置后端tomcat服务器
4.1 配置node1
两台后端服务器配置大致相同，下面展示了node1的配置。
# vim /usr/local/tomcat/conf/server.xml
#添加虚拟主机，并且设置为默认主机
<Engine name="Catalina" defaultHost="test.node1.org">
<Host name="t1.magedu.org" appBase="/data/webapps" autoDeploy="true" >
</Host>
</Engine>
#准备文件目录
# mkdir /data/webapps/ROOT -pv
mkdir: created directory '/data'
mkdir: created directory '/data/webapps'
mkdir: created directory '/data/webapps/ROOT'
# vim /data/webapps/ROOT/index.jsp
<%@ page import="java.util.*" %>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>tomcat test node1</title>
</head>
<body>
<div>On <%=request.getServerName() %></div>
<div><%=request.getLocalAddr() + ":" + request.getLocalPort() %></div>
<div>SessionID = <span style="color:blue"><%=session.getId() %></span></div>
<%=new Date()%>
</body>
</html>
#设置权限
# chown -R tomcat.tomcat /data/webapps/
# systemctl restart tomcat
4.2 测试访问
在Windows端配置域名解析，然后打开浏览器访问test.node1.org:8080
由此，后端服务器可用。
五、测试nginx代理
因为在nginx配置了资源类型jsp代理，默认使用轮询反向代理到后端tomcat服务器
