Oracle 监听器没法启动（TNS-12555，TNS-12560，TNS-00525）

启动监听器没法打开，报错！

观察发现，提示没有权限：

查看.oracle文件：

[root@localhost ~]# ls -lrtd /var/tmp/.oracle drwxrwxrwt. 2 root root 4096 8\u6708   5 21:48 /var/tmp/.oracle [root@localhost ~]# ls -lrtd /tmp/.oracle drwxrwxrwt. 2 root root 4096 8\u6708   5 20:33 /tmp/.oracle

发现权限虽然是777，可是用户组和全部者不对，改为oracle:dba

[root@localhost ~]# chown -R oracle:dba /var/tmp/.oracle [root@localhost ~]# chown -R oracle:dba /tmp/.oracle [root@localhost ~]# ls -lrtd /tmp/.oracle drwxrwxrwt. 2 oracle dba 4096 8\u6708   5 20:33 /tmp/.oracle [root@localhost ~]# ls -lrtd /var/tmp/.oracle drwxrwxrwt. 2 oracle dba 4096 8\u6708   5 21:48 /var/tmp/.oracle

再次启动，成功！
