一、簡(jiǎn)介
VS/NAT道理圖：
二、系統(tǒng)情況
嘗試拓?fù)洌?
Kernel：2.6.32-279.el6.i686
LVS版本：ipvsadm-1.26
keepalived版本：keepalived-1.2.4
三、安裝
0、安裝LVS前系統(tǒng)需要安裝popt-static，kernel-devel，make，gcc，openssl-devel，lftp，libnl*，popt*
1、在兩臺(tái)Director Server上別離設(shè)置LVS+Keepalived
LVS install -------------
[[email protected]_MASTER ~]# wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.26.tar.gz
[[email protected]_MASTER ~]# ln -s /usr/src/kernels/2.6.32-279.el6.i686//usr/src/linux/
[[email protected]_MASTER ~]# tar zxvf ipvsadm-1.26.tar.gz
[[email protected]_MASTER ~]# cd ipvsadm-1.26
[[email protected]_MASTER ipvsadm-1.26]# make && make install
Keepalived install -------------
[[email protected]_MASTER ~]# wget http://www.keepalived.org/software/keepalived-1.2.4.tar.gz
[[email protected]_MASTER ~]# tar zxvf keepalived-1.2.4.tar.gz
[[email protected]_MASTER ~]# cd keepalived-1.2.4
[[email protected]_MASTER keepalived-1.2.4]# ./configure && make && make install
######### 將keepalived做成啟動(dòng)處事，利便打點(diǎn)##########
[[email protected]_MASTER ~]# cp /usr/local/etc/rc.d/init.d/keepalived /etc/init.d/
[[email protected]_MASTER ~]# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/
[[email protected]_MASTER ~]# mkdir /etc/keepalived/
[[email protected]_MASTER ~]# cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/
[[email protected]_MASTER ~]# cp /usr/local/sbin/keepalived /usr/sbin/
[[email protected]_MASTER ~]# service keepalived start | stop
2、開(kāi)啟路由轉(zhuǎn)發(fā)
[[email protected]_MASTER ~]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
[[email protected]_MASTER ~]# sysctl -p
3、設(shè)置Keepalived
[[email protected]_MASTER ~]# less /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
router_id LVS_MASTER
}
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.227
}
}
vrrp_instance LAN_GATEWAY {
state MASTER
interface eth1
virtual_router_id 52
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.10.10
}
}
virtual_server 10.0.0.227 80 {
delay_loop 6
lb_algo rr
lb_kind NAT
# persistence_timeout 5
protocol TCP
real_server 192.168.10.4 80 {
weight 3
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 80
}
}
real_server 192.168.10.5 80 {
weight 3
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 80
}
}
}
BACKUP處事器同上設(shè)置，先安裝lvs再安裝keepalived，，然后設(shè)置/etc/keepalived/keepalived.conf，只需將講明部門(mén)改一下即可。
4、別離在2臺(tái)Real Server上面配置網(wǎng)關(guān)
把網(wǎng)關(guān)都配置成：192.168.10.10
5、在2臺(tái)RealServer中別離設(shè)置HTTP
