ipvsadm与keepalived整合

标签：ipvsadm与keepalived整合

1.准备两台虚拟服务器(DR),分别安装ipvsadm和keepalived

yum -y install ipvsadm
yum -y install keepalived

2.配置keepalived.conf

        #修改IP为192.168.2.137的DR
	vi /etc/keepalived/keepalived.conf
	#修改内容如下
	! Configuration File for keepalived

	global_defs {
	   notification_email {
		root@localhost
	   }
	   notification_email_from lvs@localhost
	   smtp_server 127.0.0.1
	   smtp_connect_timeout 30
	   router_id LVS_DEVEL
	}

	vrrp_instance VI_1 {
	    state BACKUP
	    interface eth0
	    virtual_router_id 51
	    priority 50
	    advert_int 1
	    authentication {
	        auth_type PASS
	        auth_pass 1111
	    }
	    virtual_ipaddress {
	        192.168.2.150/24 dev eth0 label eth0:1
	    }
	}

	virtual_server 192.168.2.150 8080 {
	    delay_loop 6
	    lb_algo wlc
	    lb_kind DR
	    nat_mask 255.255.255.0
	    persistence_timeout 50
	    protocol TCP

	    real_server 192.168.2.137 8080 {
	        weight 1
	        HTTP_GET {
	            url {
	              path /
		      status_code 200
	            }
	            connect_timeout 3
	            nb_get_retry 3
	            delay_before_retry 3
	        }
	    }

	    real_server 192.168.2.138 8080 {
	        weight 1
	        HTTP_GET {
	            url {
	              path /
		      status_code 200
	            }
	            connect_timeout 3
	            nb_get_retry 3
	            delay_before_retry 3
	        }
	    }
	}
	
	#修改IP为192.168.2.138的DR
	vi /etc/keepalived/keepalived.conf
	#修改内容如下
	! Configuration File for keepalived

	global_defs {
	   notification_email {
		root@localhost
	   }
	   notification_email_from lvs@localhost
	   smtp_server 127.0.0.1
	   smtp_connect_timeout 30
	   router_id LVS_DEVEL
	}

	vrrp_instance VI_1 {
	    state MASTER
	    interface eth0
	    virtual_router_id 51
	    priority 110
	    advert_int 1
	    authentication {
	        auth_type PASS
	        auth_pass 1111
	    }
	    virtual_ipaddress {
	        192.168.2.150/24 dev eth0 label eth0:1
	    }
	}

	virtual_server 192.168.2.150 8080 {
	    delay_loop 6
	    lb_algo wlc
	    lb_kind DR
	    nat_mask 255.255.255.0
	    persistence_timeout 50
	    protocol TCP

	    real_server 192.168.2.137 8080 {
	        weight 1
	        HTTP_GET {
	            url {
	              path /
		      status_code 200
	            }
	            connect_timeout 3
	            nb_get_retry 3
	            delay_before_retry 3
	        }
	    }

	    real_server 192.168.2.138 8080 {
	        weight 1
	        HTTP_GET {
	            url {
	              path /
		      status_code 200
	            }
	            connect_timeout 3
	            nb_get_retry 3
	            delay_before_retry 3
	        }
	    }
	}

3.准备两台RealServer(RS)

IP为:
		192.168.2.137
		192.168.2.138

4.分别为RealServer安装httpd服务

yum -y install httpd

5.启动httpd

service httpd start

6.启动keepalived

service keepalived start
#可以查看一个是主,一个是从
ifconfig

7.请求192.168.2.150:8080可以看到访问结果
