lvs keepalived集群架構服務

lvs+keepalived

需要四台虛擬機器

lvs 主： 

dip:10.0.0.31
vip: 10.0.0.99

lvs 備

dip:10.0.0.32
vip: 10.0.0.99

web1:

rip:10.0.0.33
vip: 10.0.0.99

web2:

rip:10.0.0.34
vip: 10.0.0.99

lvs主

[root@ localhost ~]
# yum -y install ipvsadm keepalived

[root@ localhost ~]

# vim /etc/keepalived/keepalived.conf
內容如下：
vrrp_instance vi_1 
​ virtual_ipaddress 
}virtual_server 192.168.189.181 80 
​ }
​ real_server 192.168.189.164 80 
​ }
}

修改完畢後直接儲存退出啟動keepalived

[root@ localhost ~]
# service keepalived restart

配置和主基本相同，只是初始狀態和優先順序需要修改下

[root@ localhost ~]
# scp [email protected]:/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf

編輯完畢儲存退出啟動keepalived即可

[root@ localhost ~]
# service keepalived restart

檢視vip

[root@ localhost ~]
# ip a

檢視虛擬伺服器列表

[root@ localhost ~]
# ipvsadm -ln

web伺服器的配置和之前dr的配置相同

安裝httpd

[root@ localhost ~]
# yum -y install httpd

# 建立測試頁面

[root@ localhost ~]
# echo 111111 > /var/www/html/index.html
或[root@ localhost ~]
# vim /var/www/html/index.html

啟動httpd

[root@ localhost ~]
# service httpd restart

配置內容如下:**

[root@ localhost ~]
# vim ifcfg-eth0:0
device=eth0:0
onboot=yes
bootproto=static
ipaddr=10.0.0.99
netmask=255.255.255.252

新增路由規則

[root@ localhost ~]
# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
[root@ localhost ~]
# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore 
[root@ localhost ~]
# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce 
[root@ localhost ~]
# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce 
[root@ localhost ~]
# route add 10.0.0.99 dev lo

LVS Keepalived高可用主備集群搭建

通過lvs負載均衡，我們可以解決rs的單點故障問題，但是作為負載節點也存在單點故障的可能，這時我們通過keepalived主備高可用模型。軟體安裝 在192.168.71.100和192.168.71.103上安裝keepalived yum install keepalived配置keepaliv...

安裝lVS keepalived心得

接著昨天蛋疼地無網裝keepalived，今天又在裝lvs。首先按照網上的教程做 這裡就說自己遇到的問題，第乙個是找不到 usr src kernels下的核心檔案。要先rpm kernel devel才會有。其次，用ln s 軟鏈結一直鏈不上去，可以在安裝keepalived的 configure...
