这两天一直在研究AS3，初次使用，由RH73跨越到AS3，确实有很多东西不适应，配置方法也不太一样，下面就我在安装配置时出现的一些问题在这里说明一下

我的系统挂了MYSQL、PHP、APACHE2，做了SQUID和NAT、SAMBA、DHCP、SENDMAIL+SMTP认证、PROFTPD

1、安装MYSQL4.0.18
下了MYSQL以后，解压缩
引用:

./configure --prefix=/usr/local/mysql
make
make install
useradd mysql
chown -R mysql /usr/local/mysql/var

启动MYSQL，/usr/local/mysql/bin/mysqld_safe --user=mysql

2、安装APACHE 2.0.48
解压缩
引用:

./configure
make
make install


3、安装PHP 4.3.4
解压缩
引用:

./configure --with-mysql --with-apxs2=/usr/local/apache2/bin/apxs --enable-versioning --disable-debug --enable-track-vars
make
make install


修改/usr/local/apache2/conf/httpd.conf
看有没有以下两行
引用:

LoadModule php4_module modules/libphp4.so
AddType application/x-httpd-php .php

默认应该有第一行，第二行要自己添加

增加默认页面index.php
引用:

DirectoryIndex index.html index.php index.htm index.html.var


4、配置SENDMAIL
vi /etc/mail/sendmail.mc
将
引用:

dnl # TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
dnl # define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

修改为，以便支持SMTP发信认证
引用:

TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl


将
引用:

DAEMON_OPTIONS(`Port=smtp,127.0.0.1,Name=MTA')dnl

修改为，支持远程访问
引用:

DAEMON_OPTIONS(`Port=smtp,Name=MTA')dnl


将
引用:

dnl # MASQUERADE_AS(`platinum.3322.org')dnl

改为
引用:

MASQUERADE_AS(`platinum.3322.org')dnl


m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
vi /etc/mail/sendmail.cf
修改
引用:

Cwlocalhost

为
引用:

Cwlocalhost platinum.3322.org


vi /etc/mail/access 添加0.0.0.0 RELAY

vi /etc/mail/local-host-names
添加
引用:

localhost
platinum.3322.org


启动服务：
/etc/rc.d/init.d/sendmail start
/etc/rc.d/init.d/saslauthd start
setup，启用ipop3服务
/etc/rc.d/init.d/xinetd restart

测试：
adduser test
passwd test
用OUTLOOK测试

5、做ADSL拨号上网
adsl-setup
一步一步接着下一步
然后修改生成的配置文件/etc/sysconfig/network-scripts/ifcfg-ppp0
将里面的
引用:

PPPOE_TIMEOUT=60

改为
引用:

PPPOE_TIMEOUT=0

这样就不会因为没有数据传输而自动断线了

6、做NAT
vi /etc/sysctl.conf
修改
引用:

net.ipv4.ip_forward = 0

为
引用:

net.ipv4.ip_forward = 1

这样把默认允许转发打开，不用每次还有修改/proc/net/ipv4/ip_forward了
在防火墙里添加控制，允许NAT出去
引用:

/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE


7、做SQUID
我沿用的RH73的SQUID配置，但在AS3里却遇到了问题
后来仔细看提示才发现，说找不到一个DNS SERVER，奇怪，我的ADSL拨号能PING通www.163.com啊
后来发现/etc/resvol.conf为空，我添加了一个DNS SERVER就行了
我的SQUID做了1000M容量，保存HTTP的1M大小以下的文件，这里就不细说如何配置SQUID了
另外别忘了在iptables里将80端口指向SQUID的端口，我的是默认的3128

8、DHCP
我仍然沿用RH73的dhcpd.conf，结果提示错误，服务无法启动，后来发现需要加个参数
引用:

ddns-update-style ad-hoc;

我的配置文件如下
代码:

ddns-update-style ad-hoc;
max-lease-time -1;
default-lease-time -1;
option subnet-mask 255.255.255.0;
option broadcast-address 255.255.255.255;
option routers 192.168.0.1;
option domain-name-servers 192.168.0.1,202.106.196.152;
option domain-name "platinum.3322.org";
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.2 192.168.0.100;

host platinum {
hardware ethernet 00:0a:e6:a9:64:a2;
fixed-address 192.168.0.2;
}

host bchyi {
hardware ethernet 00:80:c8:e4:c1:e4;
fixed-address 192.168.0.3;
filename "/tftpboot/pxelinux.0";
}
}


9、SAMBA
这个是最头疼的，因为这个困惑了我半天的时间
最开始，我沿用RH73的配置文档，发现网上邻居能看见，却无法访问
我的配置文档如下
代码:

[global]
client code page = 936
workgroup = HOME
server string = Samba Server
security = USER
encrypt passwords = Yes
update encrypted = Yes
obey pam restrictions = Yes
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*password* %n *Retype*new*password* %n *passwd:*all*authentication*tokens*updated*successfully*
unix password sync = Yes
log file = /var/log/samba/%m.log
max log size = 0
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
wins proxy = Yes
wins support = Yes
remote announce = 192.168.0.255
remote browse sync = 192.168.0.255
create mask = 0777
directory mask = 0777
printing = lprng

[数据中心]
comment = DATACENTER
path = /share/DATACENTER
read only = No

于是我将security = DOMAIN改成了security = USER
结果发现能出来了，但是进去以后，英文目录名没问题，中文全是乱码（大方框）
在RH73和RH9里百试百灵的，怎么在AS3里不行了？
于是我ssh，直接进入我的硬盘ls了一下，结果傻了，原来RH73看到的都是中文名字，现在变成了???等东西
……
经好好先生提醒，我想起来了，可能是和字符集有关系，于是补装ttfonts-zh_CN库，结果发现少装了好多东西，关联东西太多，无奈，又重新装系统……

现在好了，ls，发现仍然是???，无奈，选择默认字符集为GB2312，ls，没事了！
/etc/rc.d/init.d/smb restart
回到网上邻居，进入，发现仍然事乱码！
看来和字符集没关系，和SAMBA的配置有关系
testparm发现，client code page = 936这句话在AS3里并不好使，提示这句话错误
难道没办法显示中文了？？？
找了N多资料，在一个老外的论坛了找到了正确配置方法（显示中文的东西竟然在老外论坛里），用这句话替代：unix charset=GB2312
现在SAMBA能用了，正确的配置文档如下
代码:

[global]
unix charset=GB2312
workgroup = HOME
server string = Samba Server
security = USER
encrypt passwords = Yes
update encrypted = Yes
obey pam restrictions = Yes
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*password* %n *Retype*new*password* %n *passwd:*all*authentication*tokens*updated*successfully*
unix password sync = Yes
log file = /var/log/samba/%m.log
max log size = 0
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
wins proxy = Yes
wins support = Yes
remote announce = 192.168.0.255
remote browse sync = 192.168.0.255
create mask = 0777
directory mask = 0777
printing = lprng

[数据中心]
comment = DATACENTER
path = /share/DATACENTER
read only = No


10、PROFTPD
这个对我来说是轻车熟路了，装了个1.2.9（最高版本，目前没漏洞），编译好
直接把配置文档贴出来吧
代码:

# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use. It establishes a single server
# and a single anonymous login. It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

ServerType standalone
DefaultServer on
AllowRetrieveRestart on
AllowOverwrite on
AllowStoreRestart on
ServerIdent on "Welcome to PLATINUM's FTP !"
DefaultRoot ~
DisplayLogin .welcome
DisplayFirstChdir .message
UseReverseDNS off
IdentLookups off
SystemLog /var/log/ftp.syslog
TransferLog /var/log/ftp.transferlog
TransferRate RETR 20 group hMovie


# MaxClientsPerUser 10 "已超过最大上限 10 个guest用户，请少后再试！"
# MaxClientsPerHost 4

# Port 21 is the standard FTP port.
Port 21

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask 002

# To prevent DoS attacks, 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.
User nobody
Group nobody

# Normally, we want files to be overwriteable.
<Directory />
AllowOverwrite on
</Directory>

<Directory /share/DATACENTER/电影>
<Limit RNFR DELE WRITE>
DenyGroup hMovie
</Limit>
</Directory>

11、网络安全问题
服务架好了，网络安全不容忽视
这是我的“反弹式”防火墙

终于写完了，不容易，这17小时没白费！
