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！
