haproxy 配置httpd和httpds负载均衡

haproxy配置httpd负载均衡

haproxy配置方法见haproxy配置及使用

环境

系统/主机名	ip
redhat 8 /LB	192.168.100.134
redhat 8 /RS1	192.168.100.132
redhat 8 /RS2	192.168.100.133

配置

//在两台RS上安装httpd
# yum -y install httpd

//关闭防火墙和selinux
# systemctl stop firewalld
# setenforce 0

//修改第二台RS的监听端口
[root@RS2 ~]# vim /etc/httpd/conf/httpd.conf 
...
Listen 8080

//RS启动并设置开机自启httpd
# systemctl enable --now httpd 

//创建测试页面
[root@RS1 ~]# echo "RS1" > /var/www/html/index.html
[root@RS2 ~]# echo "RS2" > /var/www/html/index.html

//关闭LB的防火墙和selinux
# systemctl stop firewalld
# setenforce 0

//修改LB的 haproxy配置文件  ---添加这两个主机IP和端口号
# vim /etc/haproxy/haproxy.cfg
...
    server web01 192.168.100.132:80 check inter 2000 fall 5
    server web02 192.168.100.133:8080 check inter 2000 fall 5

//重启haproxy
# pkill haproxy
# systemctl start haproxy

//访问测试
[root@LB ~]# curl 192.168.100.134

登录网页haproxy查看负载(登陆方式见haproxy配置及使用)

Haproxy搭建HTTPS负载集群

在以上配置基础下搭建https

//RS上安装mod_ssl
[root@RS1 ~]# yum -y install mod_ssl
[root@RS2 ~]# yum -y install mod_ssl

//使用默认的证书，重启服务查看443是否启动
[root@RS1 ~]# systemctl restart httpd
[root@RS2 ~]# systemctl restart httpd

//443端口已经起来
[root@RS1 ~]# ss -antl
