RHEL6.5 安装 DB2 10.5 错误 The host name is invalid

RHEL6.5上安装DB2 10.5

执行

./db2icrt -u db2fenc1 db2inst1

出错

The host name "rhel65" is invalid. Specify a valid host name

rhel65是我本机的hostname

 

#hostname

rhel65

#hostname -f

rhel65.cn.ibm.com

ping试试

[ root@rhel65 ~]# ping rhel65
PING rhel65.cn.ibm.com (9.123.140.45) 56(84) bytes of data.
64 bytes from rhel65.cn.ibm.com (9.123.140.45): icmp_seq=1 ttl=60 time=3.87 ms
64 bytes from rhel65.cn.ibm.com (9.123.140.45): icmp_seq=2 ttl=60 time=2.12 ms
64 bytes from rhel65.cn.ibm.com (9.123.140.45): icmp_seq=3 ttl=60 time=3.83 ms

发现这里解析的ip9.123.140.45, 是但实际上我本机的ip地址是 192.168.56.101

所以在/etc/hosts里面加上

192.168.56.101 rhel65.cn.ibm.com rhel65

然后再ping试试

[ root@rhel65 ~]# ping rhel65
PING rhel65.cn.ibm.com (192.168.56.101) 56(84) bytes of data.
64 bytes from rhel65.cn.ibm.com (192.168.56.101): icmp_seq=1 ttl=64 time=0.030 ms
64 bytes from rhel65.cn.ibm.com (192.168.56.101): icmp_seq=2 ttl=64 time=0.027 ms
64 bytes from rhel65.cn.ibm.com (192.168.56.101): icmp_seq=3 ttl=64 time=0.027 ms
64 bytes from rhel65.cn.ibm.com (192.168.56.101): icmp_seq=4 ttl=64 time=0.027 ms
64 bytes from rhel65.cn.ibm.com (192.168.56.101): icmp_seq=5 ttl=64 time=0.030 ms

 

 

再次运行，就可以了

执行命令：db2 update dbm cfg using svcename 50000

报错-bash: db2: command not found

再执行[root@Rhel6 instance]# source /home/db2inst1/sqllib/db2profile

[root@Rhel6 instance]# source /home/db2inst1/sqllib/db2profile
[root@Rhel6 instance]# su db2inst1
