ubuntu intrepid下安装proftpd配置postgresql后端

因为在另外一台机器上已经配置过，本以为很简单，复制过来就可以，没想到还是出问题，检查了半天，发现是group table没有设置的原因。
安装：
sudo aptitude install proftpd proftp-pgsql
配置：
在/etc/proftpd/proftpd.conf里把

＃Include /etc/proftpd/sql.conf

这行的注释去掉，然后修改/etc/proftpd/sql.conf文件，修改为：

SQLBackend postgres
SQLEngine on
SQLAuthenticate users
SQLAuthTypes Crypt Plaintext
SQLConnectInfo db@server_name_or_ip user password

RequireValidShell off

SQLUserInfo ftp.users userid passwd uid gid homedir shell
SQLGroupInfo ftp.groups groupname gid members
SQLDefaultUID 108 # CHANGE FOR YOUR FTP USERS UID FOUND IN /etc/passwd
SQLDefaultGID 1002 # CHANGE FOR YOUR FTP USERS GID, FOUND IN /etc/groups
SQLDefaultHomedir /home/ftp
RequireValidShell off

SQLNegativeCache off
# 调试时打开
#SQLLogFile /var/log/proftpd-sql

SQLNamedQuery updatecount UPDATE “count=count+1 WHERE userid=’%u’” ftp.users
SQLLOG PASS updatecount

SQLNamedQuery count SELECT “count from ftp.users where userid=’%u’”
SQLShowInfo PASS “230″ “You’ve logged on %{count} times, %u”

SQLLog STOR newfile
SQLNamedQuery newfile FREEFORM “INSERT INTO ftp.logs(userid,action,file,abs_path,bytes) VALUES (‘%U’,'upload’,'%J’,'%f’, ‘%b’)”

SQLLog RETR insertfileinfo
SQLNamedQuery insertfileinfo FREEFORM “INSERT INTO ftp.logs(userid,action,file,abs_path,bytes) VALUES (‘%U’,'download’,'%J’,'%f’, ‘%b’)”
