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  LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 06-AUG-2014 20:02:16  Copyright (c) 1991, 2009, Oracle.  All rights reserved.  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  LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 06-AUG-2014 20:02:48  Copyright (c) 1991, 2009, Oracle.  All rights reserved.  Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) TNS-12541: TNS:no listener  TNS-12560: TNS:protocol adapter error   TNS-00511: No listener    Linux Error: 111: Connection refused Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))) TNS-12541: TNS:no listener  TNS-12560: TNS:protocol adapter error   TNS-00511: No listener    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：

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
