Tomcat 完成反向代理集群

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 {
    listen       80;
    server_name  localhost;
    access_log  /var/log/nginx/proxy.access.log  main;

    location / {
       root /usr/share/nginx/html;
       index index.html index.htm;
       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.conf
upstream testweb {
	server 192.168.50.114:8081 weight=1 max_fails=1 fail_timeout=2s;
	server 192.168.50.114:8082 weight=1 max_fails=1 fail_timeout=2s;
}

启动nginx

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

3、在浏览器上进行访问测试，配置的tomcat服务器是上一篇的tomcat多实例部分
