oracle 监听器无法启动（tns-12555，tns-12560，tns-00525）

[oracle@localhost ~]$ lsnrctl start

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，但是用户组和所有者不对，，改成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！
