How to config localhost firewall on Oracle Database RAC in Linux/Windows 如何設定本機防火牆？

Oracle文件暫時找不到，Google Search出來的結果如下

Example Firewalld:

# Public IP subnet
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.10.10.0/24" port protocol="tcp" port="1-65535" accept"
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.10.10.0/24" port protocol="udp" port="1-65535" accept"

# Private IP subnet, need to config tcp/udp
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.10.11.0/24" port protocol="tcp" port="1-65535" accept"
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.10.11.0/24" port protocol="udp" port="1-65535" accept"

# Localhost subnet
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="169.254.0.0/16" port protocol="tcp" port="1-65535" accept"
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="169.254.0.0/16" port protocol="udp" port="1-65535" accept"

設定完記得要重啟

firewall-cmd --reload

Grid_home\bin\oracle.exe - Oracle ASM executable (if using Oracle ASM for storage)

Grid_home\bin\racgvip.exe - Virtual Internet Protocol Configuration Assistant

Grid_home\bin\evmd.exe - OracleEVMService

Grid_home\bin\crsd.exe - OracleCRService

Grid_home\bin\ocssd.exe - OracleCSService

Grid_home\bin\octssd.exe - Cluster Time Synchronization Service daemon

Grid_home\bin\mDNSResponder.exe - multicast-DNS Responder Daemon

Grid_home\bin\gipcd.exe - Grid IPC daemon

Grid_home\bin\gnsd.exe - Grid Naming Service daemon
