Oracle 监听器无法启动（TNS-12537，TNS-12560，TNS-00507）

Oracle启动监听报错，提示 连接中断

[oracle@localhost ~]$ 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:

[oracle@localhost ~]$ lsnrctl status

  TNS-00511: 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

[root@localhost ~]# 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

[oracle@oracle ~]$ lsnrctl start
