#tail /var/log/messages 配置都对但是nginx报错，修改nginx的配置即可 Mar 31 09:34:47 FrankTest02 IPaddr(IPaddr_192.168.1.150)[11820]: INFO: /usr/libexec/heartbeat/send_arp -i 200 -r 5 -p /var/run/resource-agents/send_arp-192.168.1.150 eth0 192.168.1.150 auto not_used not_used Mar 31 09:34:47 FrankTest02 /usr/lib/ocf/resource.d//heartbeat/IPaddr(IPaddr_192.168.1.150)[11794]: INFO: Success Mar 31 09:34:47 FrankTest02 ResourceManager(default)[11659]: info: Running /etc/init.d/nginx start Mar 31 09:34:48 FrankTest02 ResourceManager(default)[11659]: ERROR: Return code 1 from /etc/init.d/nginx Mar 31 09:34:48 FrankTest02 ResourceManager(default)[11659]: CRIT: Giving up resources due to failure of nginx Mar 31 09:34:48 FrankTest02 ResourceManager(default)[11659]: info: Releasing resource group: master 192.168.1.150/24/eth0:0 nginx Mar 31 09:34:48 FrankTest02 ResourceManager(default)[11659]: info: Running /etc/init.d/nginx stop Mar 31 09:34:48 FrankTest02 ResourceManager(default)[11659]: info: Running /etc/ha.d/resource.d/IPaddr 192.168.1.150/24/eth0:0 stop Mar 31 09:34:48 FrankTest02 IPaddr(IPaddr_192.168.1.150)[12022]: INFO: IP status = ok, IP_CIP= Mar 31 09:34:48 FrankTest02 /usr/lib/ocf/resource.d//heartbeat/IPaddr(IPaddr_192.168.1.150)[11996]: INFO: Success
#tail /var/log/messages如果不启动从服务器，所以启动了主服务器以后要启动从服务器 原因：我想到一个问题，我记得上课的时候我只启动主上的heartbeat，从还为启动的时候，主上是不会启动vip和nginx服务的，这是因为，主有一个判断，只有当从节点一切准备就绪时，主才会正常工作。因为它要保证HA集群的可用性，如果从连heartbeat服务都不开启，只能说明这是一个单点，所以它要罢工！ Mar 31 09:13:20 FrankTest02 ResourceManager(default)[10114]: info: Releasing resource group: master 192.168.1.150/24/eth0:0 nginx Mar 31 09:13:20 FrankTest02 ResourceManager(default)[10114]: info: Running /etc/init.d/nginx stop Mar 31 09:13:20 FrankTest02 ResourceManager(default)[10114]: info: Running /etc/ha.d/resource.d/IPaddr 192.168.1.150/24/eth0:0 stop Mar 31 09:13:20 FrankTest02 IPaddr(IPaddr_192.168.1.150)[10477]: INFO: IP status = ok, IP_CIP= Mar 31 09:13:20 FrankTest02 /usr/lib/ocf/resource.d//heartbeat/IPaddr(IPaddr_192.168.1.150)[10451]: INFO: Success Mar 31 09:13:29 FrankTest02 heartbeat: [9899]: info: Local Resource acquisition completed.

重启主从，
#ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:58:45:92 brd ff:ff:ff:ff:ff:ff inet 192.168.1.110/24 brd 192.168.1.255 scope global eth0 inet 192.168.1.150/24 brd 192.168.1.255 scope global secondary eth0:0 inet6 fe80::20c:29ff:fe58:4592/64 scope link valid_lft forever preferred_lft forever
但是从上ip addr，还是存在eth1的提示，但是已经把eth1这个网卡删除了应该就没问题了

PS：ha.cf上的ucast试验用eth0，线上建议用不同的网卡eth1或者用串口把两个连起来，什么是串口
