autoindex on;

改为off后，显示出文件的大概大小，单位是kB或者MB或者GB
autoindex_localtime on;
默认为off，显示的文件时间为GMT时间。
改为on后，显示的文件时间为文件的服务器时间

[root@linux-node1 ~]# htpasswd --help
Usage:
htpasswd [-cimBdpsDv] [-C cost] passwordfile username
htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password
htpasswd -n[imBdps] [-C cost] username
htpasswd -nb[mBdps] [-C cost] username password
-c Create a new file.
-n Don't update file; display results on stdout.
-b Use the password from the command line rather than prompting for it.
-i Read password from stdin without verification (for script usage).
-m Force MD5 encryption of the password (default).
-B Force bcrypt encryption of the password (very secure).
-C Set the computing time used for the bcrypt algorithm
(higher is more secure but slower, default: 5, valid: 4 to 31).
-d Force CRYPT encryption of the password (8 chars max, insecure).
-s Force SHA encryption of the password (insecure).
-p Do not encrypt the password (plaintext, insecure).
-D Delete the specified user.
-v Verify password for the specified user.
On other systems than Windows and NetWare the '-p' flag will probably not work.
The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
