piranha + lvs图形化配置
调度主机：192.168.0.85；192.168.0.52realserver:192.168.0.96;192.168.0.66
realserver:
# ifconfig lo:0 192.168.0.136 netmask 255.255.255.255 up
#route add -host 192.168.0.136 dev lo:0
# yum install -y httpd
# vim /var/www/html/index.html
# /etc/init.d/httpd start
192.168.0.85配置：
# yum install -y piranha
# rpm -q ipvsadm
ipvsadm-1.25-9.el6.x86_64
# /etc/init.d/piranha-gui start
Starting piranha-gui:
# netstat -antlp
tcp 0 0 :::3636 :::* LISTEN 1345/httpd
# piranha-passwd
New Password:
Verify:
Adding password for user piranha
现在浏览器访问192.168.0.85:3636
username:piranha
passwd:刚才设置的
添加一个物理网卡：
# cp ifcfg-eth0 ifcfg-eth1
根据 /etc/udev/rules.d/70-persistent-net.rules 文件中的提示修改ifcfg-eth1,该网卡用于心跳检测的！
# vim /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
BOOTPROTO="none"
HWADDR="52:54:00:8d:82:cc"
NM_CONTROLLED="yes"
ONBOOT="yes"
IPADDR=10.0.0.85
NETMASK=255.255.255.0
通过浏览器配置配置文件：
GLOBAL SETTINGS =>
Primary server public IP:192.168.0.85
Primary server private IP:10.0.0.85
=>ACCEPT,此时，就已经在/etc/sysconfig/ha/lvs.cf写入配置
REDUNDANCY=>
Redundant server public IP:192.168.0.52
Redundant server private IP:10.0.0.52
勾选Monitor NIC links for failures和Syncdaemon
=>ACEPT
根据服务配置一下VIRTUAL SERVERS
浏览器页面=>VIRTUAL SERVERS=>(DE)ACTIVATE
浏览器页面=>VIRTUAL SERVERS=>(DE)ACTIVATE=>EDIT=>REAL SERVER=选中主机并激活
# /etc/init.d/pulse start
Starting pulse:
# ipvsadm -L
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags

TCPserver36.example.com:http rr
-> desktop66.example.com:http Route 1 0 0
-> desktop96.example.com:http Route 1 0 0
此时在192.168.0.52上也安装pinanha 和配置虚拟心跳IP
