RAC安装时出现PRKC-1024 : Invalid netmask: eth0
PRKC-1024 : Invalid netmask: eth0
add nodeapps -n zbxdb1 -A zbxdb1-vip//eth0 on node=zbxdb1 ... failed
Failed to add Nodeapps at /oracle/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 9373.

最开始把问题定位在网卡上。但是修改网卡配置，ifup, ifdown, systemctl restart network始终未能解决问题
静下心来，仔细看日志：
发现有这么一行：
Using configuration parameter file: /oracle/app/11.2.0/grid/crs/install/crsconfig_params
于是看了一下这个参数文件：
怪不得老是出现问题:
手动修改参数文件：
NEW_NODEVIPS='zbxdb1-vip/255.255.255.0/eth0,zbxdb2-vip/255.255.255.0/eth0'
重新执行root.sh
居然成功了
以下是完整错误日志：
