查看文件权限：

[[email protected] ~]# ls -lZ /etc/updatedb.conf
-rw-r--r--. root root unconfined_u:object_r:user_tmp_t:s0 /etc/updatedb.conf

由于SElinux引起，重置设置，修复

[[email protected] ~]# restorecon -RFv /etc/updatedb.conf
restorecon reset /etc/updatedb.conf context unconfined_u:object_r:user_tmp_t:s0->system_u:object_r:etc_t:s0
