LVS准备——ipvsadm + keepalived 安装步骤

最近研究LVS，刚刚接触好多东西都不懂，把一些记录下来，如果有不对的地方请指出，谢谢~~

安装的系统：

[root@localhost ~]# uname -aLinux localhost.localdomain 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:12 EDT 2008 i686 i686 i386 GNU/Linux

在/usr/src文件夹下：

安装ipvsadm-1.24
1， wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
2，创建一个连接文件：ln -sv /usr/src/kernels/2.6.18-92.el5-i686/ /usr/src/linux
3，解压：tar zxvf ipvsadm-1.24.tar.gz
4，安装：cd ipvsadm-1.24; make; 然后 make install
5，执行ipvsadm，检验ipvsadm 是否被正确安装 

执行ipvsadm的结果是：

[root@localhost ipvsadm-1.24]# ipvsadmIP Virtual Server version 1.2.1 (size=4096)Prot LocalAddress:Port Scheduler Flags  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn

应该是安装成功了！

安装keepalived-1.1.20 （当前最新是1.2.2，发现安装不上，就选了1.1.*的最新一个版本）
1，wget http://www.keepalived.org/software/keepalived-1.1.20.tar.gz
2，解压：tar zxvf keepalived-1.1.20.tar.gz
3，安装：cd keepalived-1.1.20; ./configure –prefix=/usr/local/keepalive; make;make install
安装完成生成目录：/usr/local/keepalived 

由于指定了安装目录 所以路径变为： /usr/local/keepalive

 

 cp /usr/local/keepalived/sbin/keepalived /usr/sbin/ cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ mkdir -p /etc/keepalived cd /etc/keepalived/ 

这样子便可以使用
#/etc/init.d/keepalived 开启或者停止

[root@localhost init.d]# /etc/init.d/keepalived startStarting keepalived: [  OK  ][root@localhost init.d]# /etc/init.d/keepalived stop Stopping keepalived: [  OK  ]

如果没有指定安装目录，默认的是 /usr/local/etc

./configure && make && make install

######### 将keepalived做成启动服务，方便管理##########

[root@CentOS-LVS_MASTER ~]# cp /usr/local/etc/rc.d/init.d/keepalived /etc/init.d/[root@CentOS-LVS_MASTER ~]# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/[root@CentOS-LVS_MASTER ~]# mkdir /etc/keepalived/[root@CentOS-LVS_MASTER ~]# cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/[root@CentOS-LVS_MASTER ~]# cp /usr/local/sbin/keepalived /usr/sbin/[root@CentOS-LVS_MASTER ~]# service keepalived start | stop
