LVS + Keepalived 介绍及安装(2)

1 cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/
2 cp /usr/local/etc/rc.d/init.d/keepalived /etc/init.d/
3 cp /usr/local/sbin/keepalived /usr/sbin/
4 mkdir /etc/keepalived -p
5 cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/

7、启动并查看keepalived

[root@LVS-DR-Backup script]# /etc/init.d/keepalived start
正在启动 keepalived：                                      [确定]
[root@LVS-DR-Backup script]# ipvsadm

[root@LVS-DR-Backup script]#

8、至此安装完成，下一章，keepalived.conf详解。
