redhat6.9安装oracle11.2.0.4 执行root.sh脚本，发现scp文件至节点2无法传输报错

查询MOS
Linux: GI installation fails as bindv6only is set to 1: "PRCF-2010 :
All connections to the remote nodes got refused. Cannot proceed with the file transfer" (Doc ID 1999296.1) The firewall is disabled and hence not the cause of the connections being refused 虽然版本不太匹配，MOS是12.1 但是其中有关于ip6tables!!! root@node1:~$ /etc/init.d/iptables status iptables: Firewall is not running. root@node1:~$ /etc/init.d/ip6tables status ip6tables: Firewall is not running. root@node2:~$ /etc/init.d/iptables status iptables: Firewall is not running. root@node2:~$ /etc/init.d/ip6tables status ip6tables: Firewall is not running. SOLUTION The issue is caused by the kernel parameter net.ipv6.bindv6only being set to 1 as seen below grid@node1:~> sysctl net.ipv6.bindv6only net.ipv6.bindv6only = 1 grid@node1:~> The solution is to set net.ipv6.bindv6only to 0 and install the Grid Infrastructure software node1:~ # sysctl net.ipv6.bindv6only=0 net.ipv6.bindv6only = 0 node1:~ #
实际环境检测
系统安装redhat6.9 防火墙已关闭，但是对于ipv6的服务并未关闭！！！ 因此是这个问题导致的，关闭ipv6服务后，ok 两个节点都要操作
