 TNS-12560: TNS:protocol adapter error
  TNS-00512: Address already in use
   Linux Error: 98: Address already in use

修改/etc/hosts

[oracle@localhost ~]$ more /etc/hosts
#127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
#192.168.1.251   localhost localhost.localdomain localhost4 localhost4.localdoma
#192.168.1.251 www.fbird.cn
124.232.153.226(此处为修改后IP)  localhost localhost.localdomain

[oracle@localhost ~]$ more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.localdomain  --hostname要和主机名一致

[oracle@localhost admin]$ more listener.ora
