【IT168 服务器学院】INN安装步骤小结
    1、用vipw修改/etc/passwd文件，改为news:*:8:8:News   Subsystem:/usr/local/news:/bin/sh

    2、 $tar zxvf inn-2.4.0.tar.gz
    $cd inn-2.4.0
    $./configure
    $make && make install
    缺省安装在/usr/local/news下

    3、修改 etc/inn.conf

    hiscachesize: 256
    artcutoff: 60
    maxartsize: 100000
    localmaxartsize: 100000
    enableoverview: true
    ovmethod: tradindexed
    spoolfirst: false
    执行inncheck,检查inn.conf,没有错误提示

    4、文章过期策略设置
    修改expire.ctl 如下：
    ##This entry uses the syntax appropriate when groupbaseexpiry is true in inn.conf.
    ##This is an entry based on storage class, used when groupbaseexpiry is flase.
    #0:10:never:never

    5、初始化history文件
    $cd /usr/local/news/db
    $touch history
    $../bin/makedbz -i
    $for i in history.n*; do i=${i#history.n.};mv history.n.$i history.$i ;done
    有的shell执行不了，也可以手工改正
    (起的作用是把history.n.*改名为history.*)
    $chown news:news history*
    $chmod 644 history*

    6、建立新的新闻组
    ctlinnd newgroup test1
    ctlinnd newgroup test2

    7、用mkuserdb.pl建立userpass文件，userpass文件一般存放在/usr/local/news/db下

    8、修改storage.conf文件，加入
    method tradspool {
    newsgroups: *
    class: 1
    }

    9、修改readers.conf,格式如下
    auth admin {
    hosts: *
    auth: "ckpasswd -f /usr/local/news/db/userpass"
    default: <FAIL>
    default-domain: <UNKNOWN>
    }

    auth "localhost" {
    hosts: "localhost, 127.0.0.1, stdin"
    default: "<localhost>"
    }
    .
    .
    .

    access user1 {
    users: "zhenhua@<UNKNOWN>, !<FAIL>@<UNKNOWN>"
    newsgroups: "test2,!control.*,!junk,!control"
    access: RP
    }

    access user2 {
    users: "yingjia@<UNKNOWN>, !<FAIL>@<UNKNOWN>"
    newsgroups: "test1,test2,!control.*,!junk,!control"
    access: RP
    }

    access "localhost" {
    users: "<localhost>"
    newsgroups: "*"
    access: RPA
    }

    access fail {
    users: "<FAIL>@*"
    newsgroups: !*
    }

    <
    配置 syslog，记录日志

    $ touch /usr/local/news/log/news.crit
    $ touch /usr/local/news/log/news.err
    $ touch /usr/local/news/log/news.notice
    $ chown news /usr/local/news/log/news.*
    $ chgrp news /usr/local/news/log/news.*
    $ cat >> /etc/syslog.conf << END
    news.crit /usr/local/news/log/news.crit
    news.err /usr/local/news/log/news.err
    news.notice /usr/local/news/log/news.notice
    END

    $ kill -1 `cat /var/run/syslog.pid`

    >

    10、启动news服务:
    $su - news
    $rc.news
    用netstat -an | grep LISTEN 命令查看119端口是否起来

    11、用outlookexpress测试新闻组
    yingjia可以订阅test1,test2
    zhenhua只能订阅test2

    12.系统启动时，自动启动新闻组服务器 
    确定/etc/rc中有执行rc.local的部分，然后在rc.local（如没有，则新建）中加入：
    su news -c /usr/local/news/bin/rc.news
