查看是否有ipvsadm软件
1. 检查ipvsadm是否安装成功.可以直接输入 [root@localhost ~]# ipvsadm IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn 2. 检查模版是否加入内核 [root@localhost ~]# lsmod |grep ip_vs ip_vs 78081 0
安装keepalived
1. keepalived-1.2.1.tar.gz # 解压这个文件并且安装 (tar -zxvf keepalived-1.2.1.tar.gz) 2. ./configure --prefix=/hnisi/keepalived/ --with-kernel-dir=/usr/src/kernels/2.6.18-164.el5-i686 3.make 4.make install 5.配置文件的路径 cp /hnisi/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ cp /hnisi/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ cp /hnisi/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ cp /hnisi/keepalived/sbin/keepalived /sbin/
配置主keepalived
vim /etc/keepalived/keepalived.conf
#global define global_defs { router_id LVS_T1 } vrrp_sync_group bl_group { group { bl_one } } vrrp_instance bl_one { state MASTER interface eth0 lvs_sync_daemon_interface eth0 virtual_router_id 38 priority 150 advert_int 3 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 192.168.96.100 } } virtual_server 192.168.96.100 8099 { delay_loop 3 lb_algo rr lb_kind DR persistence_timeout 1 protocol TCP real_server 192.168.96.33 8099 { weight 1 TCP_CHECK { connect_timeout 10 nb_get_retry 3 delay_before_retry 3 connect_port 8099 } } real_server 192.168.96.4 8099 { weight 1 TCP_CHECK { connect_timeout 10 nb_get_retry 3 delay_before_retry 3 connect_port 8099 } } }
配置备keepalived
略
分别在主备上启动keepalived
[root@ip_lb home]# /etc/init.d/keepalived start
Starting keepalived: [ OK ]
[root@ip_lb home]# tail -f /var/log/message
# PS:这里说的LVS，并不是用ipvsadm软件配置，而是直接用keepalived的virtual_server配置项控制的。
# 安装ipvsadm只是可以看到负载状况，其实只需要keepalived也可以实现负载均衡集群。
在web1服务器配置LVS-DR
vim /etc/init.d/lvsDR_node（web1主机）
#! /bin/sh # descript : start real server DR VIP=192.168.96.100 . /etc/rc.d/init.d/functions case "$1" in start) echo "start LVS of RealServer DR" /sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce ;; stop) /sbin/ifconfig lo:0 down echo "close LVS of RealServer DR" echo "0" > /proc/sys/net/ipv4/conf/all/arp_ignore echo "0" > /proc/sys/net/ipv4/conf/all/arp_announce ;; *) echo "Usage : $0 {start|stop}" exit 1 esac
把这个文件复制到web2主机上
在web1和web2上分别启动这个脚本:
/etc/init.d/lvsDR_node start
测试是否可以负载均衡
#! /bin/sh for((i=1;i<=100;i++));do curl http://192.168.96.100:8099 >> /tmp/q; done
