RAC白名单管理

一.查看本地IP

[oracle@rac1 ~]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

# public IP
10.204.38.15 rac1.localdomain   rac1
10.204.38.16 rac2.localdomain   rac2
# private IP
192.168.38.15 rac1-priv.localdomain  rac1-priv
192.168.38.16 rac2-priv.localdomain  rac2-priv
# virtual IP
10.204.38.19 rac1-vip.localdomain   rac1-vip
10.204.38.20 rac2-vip.localdomain   rac2-vip
# rac scan IP
10.204.38.17 rac-cluster-scan.localdomain  rac-cluster-scan
[oracle@rac1 ~]$

记录所有 public IP，private IP，virtual IP，rac scan IP

二.修改集群监听配置

1.使用grid用户登录

[oracle@rac1 ~]$ su - grid
Password: 
Last login: Fri Aug 11 13:35:54 CST 2023 on pts/3
[grid@rac1 ~]$

2.修改sqlnet.ora文件

白名单规则中必须将[本地IP](# 一.查看本地IP) 全部添加，否则监听会出现异常

RAC中所有节点都要修改sqlnet.ora

[grid@rac1 ~]$ echo $ORACLE_HOME
/u01/app/11.2.0/grid
[grid@rac1 ~]$ vim /u01/app/11.2.0/grid/network/admin/sqlnet.ora
g sqlnet.ora.rac1 Network Configuration File: /u01/app/11.2.0/grid/network/admin/sqlnet.ora.rac1
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = /u01/app/oracle
SQLNET.EXPIRE_TIME ＝ 60
tcp.validnode_checking=yes #开启ip限制
tcp.invited_nodes=(11.64.0.31,11.64.0.65,11.64.0.41,10.204.38.15,10.204.38.16,10.204.38.17,192.168.38.15,192.168.38.16,10.204.38.19,10.204.38.20,11.64.0.64,11.64.0.47,11.64.0.61,11.64.0.36,11.64.0.60,1.64.0.44,11.64.0.57,11.64.0.34,11.64.0.52,11.64.0.59,11.64.0.32,11.64.0.63,11.64.0.42,11.64.0.31,10.204.38.18,11.64.3.51,11.64.3.52,11.64.3.53,11.64.3.54,11.64.3.55,11.64.3.56,11.64.3.57,11.64.3.58,11.64.3.59,11.64.3.60,11.64.3.61,10.204.38.13) #设置白名单规则
SQLNET.AUTHENTICATION_SERVICES = NONE
~

3.重启监听

每个节点分别启停，不能用 lsnrctl reload

[grid@rac1 ~]$ srvctl stop listener -n rac1
[grid@rac1 ~]$ srvctl start listener -n rac1
[grid@rac1 ~]$ srvctl stop listener -n rac2
[grid@rac1 ~]$ srvctl start listener -n rac2

4.查看监听状态

[grid@rac1 ~]$ lsnrctl status
