LVS NAT模式
4台机器、一台Director server、两台Real server （web01、web02）、一台windows 7客户机
Director 有两块网卡：eth0:192.168.119.132（内网）
eth1:192.168.94.130 （外网）
web01网卡IP：192.168.119.134（内网）
web02网卡IP：192.168.119.134（内网）
director 安装ipvsadm
[root@lvs /]# yum -y install ipvsadm
给Director 添加一块网卡eth1
[root@lvs /]# sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config （关闭selinux重启生效） [root@lvs /]# /etc/init.d/iptables stop iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] [root@lvs /]# dmesg | grep -in eth 1583:e1000 0000:02:01.0: eth0: (PCI:66MHz:32-bit) 00:0c:29:21:bc:27 1584:e1000 0000:02:01.0: eth0: Intel(R) PRO/1000 Network Connection 1587:e1000 0000:02:05.0: eth1: (PCI:66MHz:32-bit) 00:0c:29:21:bc:31 1588:e1000 0000:02:05.0: eth1: Intel(R) PRO/1000 Network Connection 1610:e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None 1611:eth0: no IPv6 routers present [root@lvs /]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 [root@lvs /]# vim /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 HWADDR=00:0C:29:21:BC:31 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp [root@lvs /]# /etc/init.d/network reload Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0... done.

两台Real server 安装httpd或nginx
[root@web01 /]# sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config [root@web01 /]# /etc/init.d/iptables stop iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] [root@web01 /]# yum -y install httpd [root@web01 /]# vim /etc/httpd/conf/httpd.conf [root@web01 /]# [root@web01 /]# echo "web01" > /var/www/html/index.html [root@web01 /]# /etc/init.d/httpd start Starting httpd: [ OK ] [root@web01 /]# curl 192.168.119.134 web01 [root@web02 /]# sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config [root@web02 /]# /etc/init.d/iptables stop iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] [root@web02 /]# yum -y install httpd [root@web02 /]# vim /etc/httpd/conf/httpd.conf [root@web02 /]# echo "web02" > /var/www/html/index.html [root@web02 /]# /etc/init.d/httpd start Starting httpd: [ OK ] [root@web02 /]# curl 192.168.119.135 web02
