# To prevent DoSattacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).
MaxInstances 30
# Set the user and group under which the server will run.

进入mysql数据库命令状态:
# mysql –p
提示输入密码
建立数据库FTP(注意大小写和每句话后面的“;”)
CREATE DATABASE FTP;
然后在这个数据库中建立一个用户表FTPUSERS,这个表是必须的:
use FTP;
create table FTPUSERS (
userid TEXT NOT NULL,
passwd TEXT NOT NULL,
uid INT NOT NULL,
gid INT NOT NULL,
homedir TEXT,
shell TEXT
);
此表格是为了用户认证所需要的,其中userid、passwd是必不可少的,userid是用做FTP服务的用户名;passwd是指此用户的密码; uid是系统用户的ID,也就是所映射的系统用户;gid是所属系统组的ID;homedir是该用户所在的HOME目录;shell可以为该用户指定相 应的shell。当然你可以建立更多的字段,例如:用来记录用户登录次数的count,或者是日期的date,如果你对配置熟悉了之后,你可以根据自己的 喜欢添加更多的功能。在此就不多讲。
为了提供更多的功能,我们添加另外一个需要的表:FTPGRPS,也就是确定组的表格,这里是它的格式:
create table FTPGRPS (
groupname TEXT NOT NULL,
gid SMALLINT NOT NULL,
members TEXT NOT NULL
);
其中groupname是组的名称,gid是系统组的ID,members是组的成员。注意:多成员,他们之间要用逗号隔开,不能使用空格。
