NGINX+Tomcat负载均衡、动静分离

部署Tomcat页面

Tomcat1

[root@localhost ~]#cd /usr/local/tomcat1/webapps/

[root@localhost webapps]#ls

docs examples host-manager manager ROOT

[root@localhost webapps]#mkdir mm

[root@localhost webapps]#cd mm

[root@localhost mm]#vim test.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

JSP tomcat1 page

<% out.println("动态页面 1,Hello Tomcat1");%>

Tomcat2

[root@localhost mm]#cd /usr/local/tomcat2/webapps/

[root@localhost webapps]#mkdir mm

[root@localhost webapps]#cd mm

[root@localhost webapps]#vim test.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

配置NGINX服务

yum安装NGINX

[root@localhost opt]# cd /etc/yum.repos.d

[root@localhost yum.repos.d]# ls

CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo

CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo

[root@localhost yum.repos.d]# mkdir repo.bak

[root@localhost yum.repos.d]# mv *.repo repo.bak

[root@localhost yum.repos.d]# ls

repo.bak

[root@localhost yum.repos.d]# vim nginx.repo

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/$releasever/$basearch/

gpgcheck=1

enabled=1

gpgkey=https://nginx.org/keys/nginx_signing.key

module_hotfixes=true

[root@localhost yum.repos.d]# yum -y install nginx

验证中 : 1:nginx-1.24.0-1.el7.ngx.x86_64 1/1

已安装:

nginx.x86_64 1:1.24.0-1.el7.ngx

完毕！

部署NGINX页面

[root@localhost ~]# cd /usr/share/nginx/html/

[root@localhost html]# ls

50x.html index.html

[root@localhost html]# mkdir mm

[root@localhost html]# cd mm

[root@localhost html]# echo '

this is nginx static web page!

' >test.html

[root@localhost mm]# ls

test.html

实现动静分离

[root@localhost html]# cd /etc/nginx/

[root@localhost nginx]# vim nginx.conf

在 #gzip on;下一行加入

upstream tomcat {

server 192.168.65.101:8080 weight=1

server 192.168.65.102:8080 weight=1

server 192.168.65.102:8082 weight=1

}

[root@localhost nginx]# cd conf.d/

[root@localhost conf.d]# ls

default.conf

[root@localhost conf.d]# vim default.conf

location ~* .*\.jsp$ {

proxy_pass http://tomcat;

proxy_set_header HOST $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

[root@localhost nginx]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

负载均衡

将192.168.65.104主机的nginx.repo拷贝到192.168.65.103

[root@localhost ~]# cd /etc/yum.repos.d

[root@localhost yum.repos.d]# ls
