Oracle 监听lsnrctl命令启动报错（TNS-12537，TNS-12560，TNS-00507）

LINUX登录oracle用户，通过lsnrctl start命令启动数据库时，报错以下：

“ [oracle@localhost ~]$ lsnrctl start

TNS⑴2537: TNS:connection closed
TNS⑴2560: TNS:protocol adapter error
Linux Error: 29: Illegal seek

“`

缘由：
/etc/hosts内有两个localhost的主机名，监听冲突。

解决方法:
1、修改其中1个主机名，比如oracle，履行以下命令。

hostname oracle

2、在/etc/hosts内修改1个主机名为oracle。

[root@oracle etc]# cat /etc/hosts
127.0.0.1 localhost
::1 oracle

3、在/etc/sysconfig/network修改主机名为oracle。

[root@oracle etc]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=oracle

4、重新启动，在oracle用户下履行lsnrctl start。

[oracle@oracle ~]$ lsnrctl start
