▲POWER HA的简单配置过程▲.doc

环境：两台52A，AIX5305 HA5.4应用：weblogicHA的配置都在一台机器上完成一、第1阶段1、 IP规划vi编辑etc/hosts（两台机器上都配置）127.0.0.1 loopback localhost #loopback (lo0) name address192.168.1.110 node1_boot1 node1192.168.1.111 node 2_boot1 node2192.168.2.110 node 1_boot2192.168.2.111 node 2_boot2 （此4个地址 可自行配置，设在不同网段） 10.32.127.23 node 1_per10.32.127.24 node 2_per10.32.127.32 app_svc （此3个地址客户提供）2、 配置网卡基本上使用小机自带的双端口网卡。smitty tcpip en0: boot1 en1: boot23、 创建应用系统启动和停止脚本的目录#touch /etc/hacmp/appstart.sh#touch /etc/hacmp/appstop.sh#chmod 755 app*4、 创建串口设备smitty tty 选择tty类型为tty rs232，端口为0，波特率为9600测试: # stty + Fallover Policy Fallover To Next Prio + Fallback Policy Fallback To Higher Pr +如果是双机互备的话以同样方法建立另一个资源组 * Resource Group Name rg_node2 Participating Nodes (Default Node Priority) ha_node2 ha_node1 + “Participating Nodes”选项决定了资源组中节点的优先级，写在前面的节点其优先级高于后面的节点。 根据实际需求决定资源组的：“Startup Policy”、“Fallover Policy”、“Fallback Policy”。 Startup Policy：Online On Home Node Only： 只在主节点启动。在 “Participating Nodes”中写在第一位的节点启动。Online On First Available Node：在第一个启动的节点启动。在“Participating Nodes”中所选择的所有节点中最先启动的节点上启动。Online Using Distribution Policy：按照分布策略启动Online On All Available Nodes：在所有启动的节点中启动。做并发群集时选择此项。如：Oracle RAC Fallover Policy：Fallover To Next Priority Node In The List：节点失败时资源组迁移到下一优先级节点Fallover Using Dynamic Node Priority：节点失败时动态选择迁移节点Bring Offline (On Error Node Only)：将资源组下线 Fallback Policy：Fallback To Higher Priority Node In The List：节点恢复时资源组返回优先级高的节点Never Fallback：不进行资源组回迁4.2.2.2 配置资源组属性 # smitty hacmp Extended Configuration Extended Resource Configuration Hacmp Extended Resource group Configuration Change/Show Resources and Attributes for a Resource Group Resource Group Name rg_node1 Participating Nodes (Default Node Priority) ha_node1 ha_node2 Startup Policy Online On Home Node O Fallover Policy Fallover To Next Prio Fallback Policy Fallback To Higher Pr Fallback Timer Policy (empty is immediate) + Service IP Labels/Addresses app_svc +Application Servers appserver + Volume Groups datavg+Use forced varyon of volume groups, if necessary false+Automatically Import Volume Groups ture+Filesystems (empty is ALL for VGs specified) +Filesystems Consistency Check fsck+Filesystems Recovery Method sequential+Filesystems mounted before IP configured false+Filesystems/Directories to Export +Filesystems/Directories to NFS Mount Network For NFS Mount +Tape Resources +Raw Disk PVIDs +Fast Connect Services +Communication Links +Primary Workload Manager Class +Secondary Workload Manager Class +如果是双机互备以同样方法修改另一个资源组属性5. 校验并同步HACMP配置 # smitty hacmp Extended Configuration Extended Verification and Synchronization * Verify, Synchronize or Both Both +* Automatically correct errors found during Interactively + verification? * Force synchronization if verification fails?
