ProFTPd MySQL設置

Question

我試圖在Ubuntu服務器11.10 64位上安裝ProFTPd與MySQL。但我無法登錄，總是顯示「登錄不正確」

這是我sql.conf文件：

# add the following lines to the file (don't need to remove comments from it) 

DefaultRoot ~ 

# The passwords in MySQL are encrypted using CRYPT 
SQLBackend  mysql 
SQLEngine on 
SQLAuthTypes   Plaintext Crypt 
SQLAuthenticate   users* groups* 

# used to connect to the database 
# databasename@host database_user user_password 
SQLConnectInfo ftp@localhost proftpd password 

# Here we tell ProFTPd the names of the database columns in the "usertable" 
# we want it to interact with. Match the names with those in the db 
SQLUserInfo  ftpuser userid passwd uid gid homedir shell 

# Here we tell ProFTPd the names of the database columns in the "grouptable" 
# we want it to interact with. Again the names match with those in the db 
SQLGroupInfo ftpgroup groupname gid members 

# set min UID and GID - otherwise these are 999 each 
SQLMinID  500 

# create a user's home directory on demand if it doesn't exist 
SQLHomedirOnDemand on 

# Update count every time user logs in 
SQLLog PASS updatecount 
SQLNamedQuery updatecount UPDATE "count=count+1, accessed=now() WHERE userid='%u'" ftpuser 

# Update modified everytime user uploads or deletes a file 
SQLLog STOR,DELE modified 
SQLNamedQuery modified UPDATE "modified=now() WHERE userid='%u'" ftpuser 

# User quotas 
# =========== 
QuotaEngine on 
QuotaDirectoryTally on 
QuotaDisplayUnits Mb 
QuotaShowQuotas on 

SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avail, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM ftpquotalimits WHERE name = '%{0}' AND quota_type = '%{1}'" 

SQLNamedQuery get-quota-tally SELECT "name, quota_type, bytes_in_used, bytes_out_used, bytes_xfer_used, files_in_used, files_out_used, files_xfer_used FROM ftpquotatallies WHERE name = '%{0}' AND quota_type = '%{1}'" 

SQLNamedQuery update-quota-tally UPDATE "bytes_in_used = bytes_in_used + %{0}, bytes_out_used = bytes_out_used + %{1}, bytes_xfer_used = bytes_xfer_used + %{2}, files_in_used = files_in_used + %{3}, files_out_used = files_out_used + %{4}, files_xfer_used = files_xfer_used + %{5} WHERE name = '%{6}' AND quota_type = '%{7}'" ftpquotatallies 

SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" ftpquotatallies 

QuotaLimitTable sql:/get-quota-limit 
QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally 

RootLogin off 
RequireValidShell off 
SQLNamedQuery userquota SELECT "IF ((SELECT (@availmbytes:=ROUND((`bytes_in_avail`/1048576),2)) FROM `ftpquotalimits` WHERE `name`='%u') = 0, \"No user quota applies.\", CONCAT(\"User quota: Used \", (SELECT (@usedmbytes:=ROUND((`bytes_in_used`/1048576),2)) FROM `ftpquotatallies` WHERE `name`='%u'), \"MB from \", @availmbytes, \"MB. You have \", ROUND(@availmbytes-@usedmbytes,2), \"MB available space.\"))" 

SQLShowInfo LIST "226" "%{userquota}" 
PassivePorts 60000 65000 

有什麼不對這些代碼？ SQLConnectInfo用戶名和密碼是否需要引用？
