tomcat反向代理集群配置

tomcat反向代理集群:

1.负载均衡器说明

关闭防火墙和selinux

yum安装nginx

[root@nginx-proxy ~]# cd /etc/yum.repos.d/

[root@nginx-proxy yum.repos.d]# vim nginx.repo [nginx-stable]

name=nginx stable repo

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

gpgcheck=0

enabled=1

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

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

2、配置负载均衡器

备份原配置文件并修改

[root@nginx-proxy ~] cd /etc/nginx/conf.d/

[root@nginx-proxy conf.d] cp default.conf default.conf.bak

[root@nginx-proxy conf.d]  mv default.conf tomcat.conf

[root@nginx-proxy conf.d] vim tomcat.conf

server {

                  isten 80; server_name localhost;

                access_log /var/log/nginx/proxy.access.log main;

                     location / {

                     proxy_pass http://testweb; proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr;

                      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

                    error_page 500 502 503 504 /50x.html; location = /50x.html {

                     root /usr/share/nginx/html;

          }

}

创建upstream配置文件:

[root@nginx-proxy conf.d]# vim upstream testweb {

server 192.168.50.114:8081

server 192.168.50.114:8082

}

upstream.conf

weight=1 max_fails=1 fail_timeout=2s;

weight=1 max_fails=1 fail_timeout=2s;

启动nginx

[root@nginx-proxy ~]# systemctl start nginx

3、使用命令进行访问测试

使用curl 命令进行测试，tail进行关键字提取

[root@nginx-proxy ~]# curl -s 192.168.50.118 | tail -1 8082

[root@nginx-proxy ~]# curl -s 192.168.50.118 | tail -1 8081

最后，在浏览器上进行访问测试
