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
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
