放弃用Lighttpd-mod-webdav的方法,一直不成功

opkg update 
opkg install lighttpd lighttpd-mod-cgi  lighttpd-mod-alias lighttpd-mod-webdav
opkg install php7 php7-cgi --nodeps

opkg 在安装时如果报依赖错误,加--nodeps 参数可以解决

修改 /etc/lighttpd/conf.d/30-cgi.conf

server.modules += ( "mod_cgi" )

## Plain old CGI handling
##
## For PHP don't forget to set cgi.fix_pathinfo = 1 in the php.ini.
#
cgi.assign                 = ( ".php"  => "/usr/bin/php-cgi",
                               ".pl"  => "/usr/bin/perl",

修改 /etc/lighttpd/lighttpd.conf

server.document-root        = "/mnt/sda3/www"
server.upload-dirs          = ( "/tmp" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "http"
server.groupname            = "www-data"

index-file.names            = ( "index.php", "index.html",
                                "index.htm", "default.htm",
                              )

static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

### Options that are useful but not always necessary:
#server.chroot               = "/"
server.port                 = 81
#server.bind                 = "localhost"
#server.tag                  = "lighttpd"
#server.errorlog-use-syslog  = "enable"
#server.network-backend      = "writev"

### Use IPv6 if available
#include_shell "/usr/share/lighttpd/use-ipv6.pl"

#dir-listing.encoding        = "utf-8"
server.dir-listing          = "enable"

#server.modules = (
#    "mod_cgi",
#    "mod_webdav"
#)

include "/etc/lighttpd/mime.conf"
include "/etc/lighttpd/conf.d/*.conf"

修改/etc/php.ini 中的
doc_root = "/mnt/sda3/www"

然后用OWNCLOUD来解决WEBDAV问题
