Keepalived高可用集群
目錄 keepalived keepalived實現主備 keepalived軟體起初是專為lvs負載均衡軟體設計的，用來管理並監控lvs集群系統中各個伺服器節點的狀態，後來又加入了實現高可用的vrrp功能。因此 keepalived 除了能夠管理lvs軟體外，還可以作為其他服務 例如 nginx ...
keepalived高可用集群
1.keepalived服務概念說明 keepalived軟體能幹什麼?keepalived軟體起初是專為lvs負載均衡軟體設計的，用來管理並監控lvs集群系統中各個服務節點的狀態，後來又加入了可以實現高可用的vrrp功能 keepalived軟體主要是通過vrrp協議實現高可用功能的。vrrp是v...
高可用集群 Keepalived
1.vrrp熱備 ftp,mysql,httpd,nginx,lvs 2.自動配置lvs規則 3.健康檢查 使用keepalived實現web伺服器的高可用 web伺服器ip位址分別為192.168.4.100和192.168.4.200 web伺服器的浮動vip位址為192.168.4.80 客戶...
