linux Cluster 使用piranha搭建高可用LVS piranha可以說是搭建高可用LVS集群里面，配置起來最簡單的，由redhat提供可基于web頁面進行配置，果然是親生。 Dip=director IP RIP=realserverIP VIP=virtual server IP realserver=rs ha=director
依然還是這張圖 
c.如何English very棒，那么此配置頁面對您毫無壓力，看不懂也無妨 
控制與監測選項卡，此處不需要填寫 d.全局配置 本次實驗中 公有地址填寫MSATER-director的DIP 私有地址為空 LVS工作模式選擇Director Router（DR模式） 點擊ACCEPT 
e.備胎服務器配置 點擊ENABLE啟用備胎服務器 配置如圖 
f.虛擬服務配置 點擊ADD 點擊EDIT 進行配置 
g.realserver配置 點擊ADD 點擊EDIT 點擊(DE)ACTIVATE激活服務 
h.監控腳本 點擊BLANK SEND 
配置結束，會自動生成配置文件/etc/sysconfig/ha/lvs.cf，可暫時不關閉配置web頁面 配置文件內容如下：
serial_no = 16 PRimary = 192.168.8.31 service = lvs backup_active = 1 backup = 192.168.8.32 heartbeat = 1 heartbeat_port = 539 keepalive = 6 deadtime = 18 network = direct debug_level = NONE monitor_links = 1 syncdaemon = 0 virtual dddd { active = 1 address = 192.168.8.30 eth0:1 sorry_server = 127.0.0.1 vip_nmask = 255.255.255.0 port = 80 expect = “HTTP” use_regex = 0 load_monitor = none scheduler = wlc protocol = tcp timeout = 6 reentry = 15 quiesce_server = 0 server RS1 { address = 192.168.8.33 active = 1 port = 80 weight = 1 } server RS2 { address = 192.168.8.34 active = 1 port = 80 weight = 3 } }
腳本內容如下
