LVS搭建wordpress，涉及的知识点有DNS，LAMP，NFS及LVS
- 网络拓扑图
网络环境
NFS 192.168.198.130
mysql 192.168.198.132
RS1 192.168.198.138
RS2 192.168.198.120
LVS：
DIP 192.168.198.128
vip 172.16.253.105
DNS 172.16.252.248
Client 172.16.254.150
RS1,RS2的网关指向192.168.198.128，client的DNS指向DNS服务器172.16.252.248
VS
[root@VS ~]# iptables -F
添加路由转发选项
[root@VS ~]# vim /etc/sysctl.d/99-sysctl.conf
net.ipv4.ip_forward=1
[root@VS ~]# sysctl -p /etc/sysctl.d/99-sysctl.conf \刷新生效
net.ipv4.ip_forward = 1
配置LVS的调度算法为rr轮询
[root@VS ~]# yum -y install ipvsadm
[root@VS ~]# ipvsadm -A -t 172.16.253.105:80 -s rr \-t指定TCP协议，-s指定调度算法为轮询
[root@VS ~]# ipvsadm -a -t 172.16.253.105:80 -r 192.168.198.138 -m \添加192.168.198.138 RS1服务器到LVS调度，-m 为nat类型
[root@VS ~]# ipvsadm -a -t 172.16.253.105:80 -r 192.168.198.120 -m
[root@VS ~]# ipvsadm -Ln \查看LVS调度信息

修改LVS的调度模式为wrr
[root@VS ~]# ipvsadm -E -t 172.16.253.105:80 -s wrr
[root@VS ~]# ipvsadm -Ln

[root@VS ~]# ipvsadm -e -t 172.16.253.105:80 -r 192.168.198.138 -m -w 3 \修改192.168.198.138 RS1主机的权重为3，-w 指定权重，-m为nat算法，192.168.198.120权重仍为1
