[root@centos ~]# vi /etc/clamd.d/scan.conf

# Run as another user (clamd must be started by root for this option to work)
# Default: don't drop privileges
#User clamscan　#注释掉这一行

# Path to a local socket file the daemon will listen on.
# Default: disabled (must be specified by a user)
LocalSocket /run/clamd.scan/clamd.sock　#把这一行前面的#号去掉
