SAP安装笔记

1、准备安装介质，SWPM10SP25，51050829_NW750_JavaExport、SAP_HANA_CLIENT、kernel放到/sapcd/NetWeaver目录下

进入SWPM10SP25执行./sapinst安装

2、待出现 “Open your browser and paste the following URL address to access the GUI”提示时，找到一台可以访问该主机的服务器或本地用浏览器打开对应URL。

如果出现以下界面且有报错提示连不上，然后自动停止安装过程，可以参考链接1。

我这儿遇到的问题是设置的主机名带了域名后缀，超出了14位的限制，去掉域名后就OK了。

ERROR in Selftest. Return code: 3
Connecting to HOSTNAME failed.
You can use SAPINST_GUI_HOSTNAME to override the webserver hostname for the GUI.
********************************************************************************

3、正常情况下打开链接会进入到如下页面按照指引逐步向下配置。

4、中途遇到如下报错“Error during execution of HdbCmdClazz ’GET_DEFAULT_DATA_BACKUP_LOCATION’ ”

参照如下步骤（见参考资料2）排查，端口、权限、limit设置；

 /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function OSExecute “`which csh` -c limit” 0 0
