重庆思庄技术分享——oracle RAC手动配置互信

oracle RAC手动配置互信
下面命令在一个节点上执行即可（可以在root用户下执行）：
cd /u01/app/19.0.0/grid_1/oui/prov/resources/scripts
root用户配置互信
#./sshUserSetup.sh -user root -hosts "db1 db2" -advanced -exverify –confirm
grid用户配置互信
#./sshUserSetup.sh -user grid -hosts "db1 db2" -advanced -exverify –confirm
oracle用户配置互信
#./sshUserSetup.sh -user oracle -hosts "db1 db2" -advanced -exverify -confirm
db1 db2指两个主机的主机名，根据实际情况调整
方法二
grid 用户配置
db1:
su - grid
ssh-keygen -t rsa
ssh-keygen -t dsa
cat *.pub > authorized_keys
scp /home/grid/.ssh/authorized_keys grid@db2:/home/grid/.ssh/authorized_keys
db2:
su - grid
ssh-keygen -t rsa
ssh-keygen -t dsa
cat *.pub > authorized_keys
scp /home/grid/.ssh/authorized_keys grid@db1:/home/grid/.ssh/
oracle用户配置
db1:
su - oracle
ssh-keygen -t rsa
ssh-keygen -t dsa
cat *.pub > authorized_keys
scp /home/oracle/.ssh/authorized_keys oracle@db2:/home/oracle/.ssh/authorized_keys
db2:
su - oracle
ssh-keygen -t rsa
ssh-keygen -t dsa
cat *.pub > authorized_keys
scp /home/oracle/.ssh/authorized_keys oracle@db1:/home/oracle/.ssh/
