oracle19c 集群部署的问题汇总

1、互信报错

处理过程

01、发现/etc/sysctl.conf中有net.ipv4.icmp_echo_ignore_all=1配置，注释后发现还是无法通过

02、# cat /proc/sys/net/ipv4/icmp_echo_ignore_all发现返回1，说明还是禁ping，两个节点执行#  echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all后，再次check可以顺利通过

2、policycoreutils-python未安装

处理过程

在主机上配置好yum源，执行# yum -y install policycoreutils-python   后，再次check不再提醒

#  yum -y install policycoreutils-python
