一、实验环境
二、实验步骤
LVS-keepalived 1配置(主)
实验步骤:
加载ip_vs模块
安装ipvsadm管理工具
安装keepalived源码包。
修改内核参数( /etc/sysctl.conf)文件,关闭ICMP重定向

#modprobe ip_vs
#yum install -y kernel-devel popt-devel openssl-devel
#yum install -y ipvsadm gcc gcc-c++
#tar zxf keepalived-1.2.13.tar.gz

#make && make install
#chkconfig --add keepalived
#chkconfig keepalived on
#vim /etc/sysctl.conf
#sysctl -p 使配置生效
#cd /etc/keepalived/
#cp keepalived.conf keepalived.conf.bak 备份一份以防配错
#vim keepalived.conf
#service keepalived start

NFS共享存储配置
Ip:192.168.2.1
#yum install rpcbind nfs-utils
#chkconfig rpcbind on
#chkconfig nfs on
#mkdir -p /opt/wwwroot
#vim /etc/exports
/opt/wwwroot 192.168.3.0/24(rw,sync,no_root_squash)

#netstat -anpt | grep rpcbind
WEB 1节点服务器配置
Ip:wmnet 2:192.168.1.4 vmnet 8:192.168.2.2
配置步骤:
ifcfg-lo:0配置群集ip地址192.168.1.254,子网掩码为255.255.255.255
修改内核参数( /etc/sysctl.conf)文件,关闭ARP应答。
#cd /etc/sysconfig/network-scripts/ 配置虚拟VIP
#cp ifcfg-lo ifcfg-lo:0
#vim ifcfg-lo:0
#ifconfig lo:0;ifup lo:0
#echo “/sbin/route add -host 192.168.1.254 dev lo:0” >> /etc/rc.local 重启后生效
#route add -host 192.168.1.254 dev lo:0 临时添加VIP本地访问路由,即时生效。
#vim /etc/sysctl.conf 修改内核参数( /etc/sysctl.conf)文件,关闭ARP应答。
#sysctl -p 使配置生效
#yum install -y httpd rpcbind nfs-utils
#service httpd start
#chkconfig httpd on
#echo 11111 > /var/www/html/index.html
