双机集群配置.docx

SUSE heartbeat双机集群配置环境：两台SUSE ,同时已经搭建好apache主机名：node1(8/) -主用 node2(9/) -备用心跳网卡：node1-00 node2-01配置IP地址：略操作步骤：1、在node1上配置/etc/hosts和/etc/HOSTNAME两个配置文件，内容如下：node1:/etc # more /etc/HOSTNAME node1node1:/etc # more /etc/hosts。00 node1 8 node12、在node2上配置/etc/hosts和/etc/HOSTNAME两个配置文件，内容如下：node2: # more /etc/HOSTNAME node2node2: # more /etc/hosts。01 node29 node2 3、分别对两台机器进行重新启动 init 64、由于安装SUSE时是完全安装，已经自带有heartbeat软件，只需进行配置文件的拷贝和修改即可 这里只需在node1上操作，之后采用scp将配置好的文件传到备用node2即可node1: # rpm -q heartbeat -d /usr/share/doc/packages/heartbeat/AUTHORS/usr/share/doc/packages/heartbeat/COPYING/usr/share/doc/packages/heartbeat/ChangeLog/usr/share/doc/packages/heartbeat/DirectoryMap.txt/usr/share/doc/packages/heartbeat/GettingStarted.html/usr/share/doc/packages/heartbeat/GettingStarted.txt/usr/share/doc/packages/heartbeat/HardwareGuide.html。node1: # cd /usr/share/doc/packages/heartbeatnode1:/usr/share/doc/packages/heartbeat # ls.
