Oracle启动监听报错,提示 连接中断[[email protected] ~]$ lsnrctl start

Starting /opt/oracle/11g/bin/tnslsnr: please wait...
TNS-12537: TNS:connection closed
 TNS-12560: TNS:protocol adapter error
  TNS-00507: Connection closed
   Linux Error: 29: Illegal seek
这样一般是主机名不对,观察监听状态,监听主机名为 localhost:
[[email protected] ~]$ lsnrctl status

TNS-12541: TNS:no listener
 TNS-12560: TNS:protocol adapter error

   Linux Error: 111: Connection refused
查看主机名,发现/etc/hosts内localhost只想多个地址,引发监听冲突
[[email protected] ~]# cat /etc/hosts
127.0.0.1   localhost.domain localhost
10.4.40.70  localhost
修改主机名:
1 hostname
hostname oracle
2 /etc/hosts
127.0.0.1 localhost localhost.domain
192.168.0.1 oracle
3 /etc/sysconfig/network
hostname = oracle
再次启动,成功
