8、binhwc1ock-w按“ESC”，将Vi编辑器切换至命令行模式；按“：”，将Vi编辑器切换至底行模式，输入Wq,按“Enter，保存修改并退出Vi编辑器。重启服务：执行命令/etc/init.d/cronrestart”结束本节点的NTP配置etcinit.dcronrestart登录第二个HANA服务器节点，重复上面步骤配置NTP服务器；1.12SSH免密码互联服务配置HA集群的两台服务器的需要配置SSH免密码互联服务，执行过程如下：生成认证公钥分别在两个服务器上面执行依次执行：登录服务器节点1分别执行命令ssh-keygen-trsa”；ussh-keygen-tdsa,生成公钥;执行

9、过程参考如下：erpprd1:#ssh-keygen-trsaGeneratingpub1ic/privatersakeypair.Enterfi1einwhichtosavethekey(roo1.sshid-rsa):Createddirectory,root.ssh,.Enterpassphrase(emptyfornopassphrase):(默认，直接回车)Entersamepassphraseagain:(默认，直接回车)Youridentificationhasbeensavedinroot.sshid-rsa.Yourpub1ickeyhasbeensavedinroot.ss

11、时输入root用户密码；执行该命令必须先完成etchosts文件编辑，实现主机名到IP地址的解析；SSherpprd1echo$(catroot.sshid-dsa.pub)/root/.ssh/authorized_keysMsshsrmapp2,echo$(catroot.sshid-dsa.pub)root.sshauthorized-keysssherpprd1,echo$(catrt.sshidjrsapub)rt.sshauthorizedJkeysosshsrmapp2,echo$(cat/root/.ssh/id_rsa.pub)/root/.ssh/authorized_ke
