私のLinuxシステムにprftpdとproftpd-mysql rpmをインストールしました。目的は、ネットワーク経由でftpusersのユーザー管理を実行することです。
だからproftpadminをインストールしました。ここ
/etc/proftpd.conf ファイルに次の行を追加すると、
SQLConnectInfo proftpd@localhost root root
SQLAuthenticate users groups
SQLAuthTypes Crypt Backend
SQLUserInfo users userid passwd uid gid homedir shell
SQLGroupInfo groups groupid gid members
SQLLog PASS logincount
SQLNamedQuery logincount UPDATE "login_count=login_count+1 WHERE userid='%u'" users
SQLLog PASS lastlogin
SQLNamedQuery lastlogin UPDATE "last_login=now() WHERE userid='%u'" users
SQLLog RETR dlbytescount
SQLNamedQuery dlbytescount UPDATE "dl_bytes=dl_bytes+%b WHERE userid='%u'" users
SQLLog RETR dlcount
SQLNamedQuery dlcount UPDATE "dl_count=dl_count+1 WHERE userid='%u'" users
SQLLog STOR ulbytescount
SQLNamedQuery ulbytescount UPDATE "ul_bytes=ul_bytes+%b WHERE userid='%u'" users
SQLLog STOR ulcount
SQLNamedQuery ulcount UPDATE "ul_count=ul_count+1 WHERE userid='%u'" users
SQLUserWhereClause "disabled!=1"
サービスproftpdの起動に失敗しました。
サービスの開始行を削除すると、上記の行は必須であるため、mysqlを介してユーザーを管理することはできません。
誰が私がどこに間違っているかを提案できますか？
以下で、/etc/proftpd.conf ファイルを探します。

すでに識別できるいくつかの問題は次のとおりです。
#AuthOrder does not mention mod_sql.c so it will never use mysql to identify your users.
AuthOrder mod_sql.c mod_auth_pam.c mod_auth_unix.c
#this code shouldn't be commented in your config file and should look like this or you will never enable sql_mod
<IfModule mod_dso.c>
LoadModule mod_sql.c
LoadModule mod_sql_mysql.c
# LoadModule mod_sql_postgres.c
</IfModule>
#Mysql is not used without a port, you should verify this parameter (also the password is weak but lets keep that for another moment)
SQLConnectInfo proftpd@localhost:PORT root root
#are you sure to use the correct password encryption (but that would be a problem to deal with later)

また、この仮想ユーザーは正しい権限を持つ実際のユーザーと関連付ける必要があることを覚えておいてください。
最後に、デーモンをデバッグする必要がある場合は、次の2つのガイドラインを追加します。上に構成ファイル：
