postfix安装记录四-防病毒

十六、安装clamav

1、安装clamav的支持

从早期的clamav-0.96 就需要zlib-1.2.2以上的版本的支持，我们用的版本是clamav-0.98而centos5上的版本为zlib-1.2.3因此不需要升级，但是为了确保，最好还是确认下：

[root@mail sourcepack]# rpm -qa |grep zlib

zlib-devel-1.2.3-4.el5

zlib-1.2.3-4.el5

如果不是最新的，请使用yum update zlib进行升级。

2、安装clamav ，添加clamav 运行所需的组和用户

[root@mail sourcepack]# groupadd clamav

[root@mail sourcepack]# useradd -g clamav-s /sbin/nologin -M clamav

添加配合amavisd-new使用的用户amavis

[root@mail sourcepack]# groupadd amavis

[root@mail sourcepack]# useradd -g amavis-s /sbin/nologin -M amavis

[root@mail clamav-0.98]# tar -zxvfclamav/clamav-0.98.tar.gz -C ../installpack/

[root@mail installpack]# cd clamav-0.98/

./configure --prefix=/usr/local/clamav--with-dbdir=/usr/local/clamav/share

--sysconfdir=/etc/clamav

[root@mail clamav-0.98]# make

[root@mail clamav-0.98]# make check

[root@mail clamav-0.98]# make install

3、配置Clam AntiVirus 配置文件和更新文件

[root@mail clamav-0.98]# cd /etc/clamav/

[root@mail clamav]# ll

total 64

-rw-r--r-- 1 root root 17348 Oct3 19:35 clamd.conf

-rw-r--r-- 1 root root 17348 Oct3 19:35 clamd.conf.sample

-rw-r--r-- 1 root root8627 Oct3 19:35 freshclam.conf

-rw-r--r-- 1 root root8627 Oct3 19:35 freshclam.conf.sample

（1）、编辑主配置文件：

#vi /etc/clamav/clamd.conf

注释掉第八行的Example,如下：

# Example

找到如下行

#LogFile /tmp/clamd.log

#PidFile /var/run/clamd.pid

LocalSocket /tmp/clamd.socket

#DatabaseDirectory /var/lib/clamav

#User clamav

修改为：

LogFile /var/log/clamav/clamd.log

PidFile /var/run/clamav/clamd.pid

LocalSocket/var/run/clamav/clamd.socket

DatabaseDirectory/usr/local/clamav/share

User amavis

启用以下选项

LogSyslog yes

LogFacility LOG_MAIL

LogVerbose yes

StreamMaxLength 20M(后面的数值应该与邮件服务器允许的最大附件值相一致)

root@mailclamav]# cat clamd.conf |grep -v '^#'|grep -v '^$'

LogFile/var/log/clamav/clamd.log

LogSyslogyes

LogFacilityLOG_MAIL

LogVerboseyes

PidFile/var/run/clamav/clamd.pid

DatabaseDirectory/usr/local/clamav/share

LocalSocket/var/run/clamav/clamd.socket

StreamMaxLength20M

Useramavis

(2)、编辑更新进程的配置文件freshclam.conf

注释掉Example，如下:

#Example

找到如下行

#DatabaseDirectory /var/lib/clamav

#UpdateLogFile /var/log/freshclam.log

分别修改为：

DatabaseDirectory/usr/local/clamav/share

UpdateLogFile/var/log/clamav/freshclam.log

启用以下选项：

DatabaseMirrordb.CN.clamav.net

DatabaseMirrordb.XY.clamav.net

LogSyslogyes

LogFacilityLOG_MAIL

LogVerboseyes

[root@mailclamav]# cat freshclam.conf |grep -v '^#'|grep -v '^$'

DatabaseDirectory/usr/local/clamav/share

UpdateLogFile/var/log/clamav/freshclam.log

LogVerboseyes

LogSyslogyes

LogFacilityLOG_MAIL

DatabaseMirrordb.CN.clamav.net

DatabaseMirrordatabase.clamav.net

4、建立日志所在的目录、进程与socket所在的目录，并让它属于clamav用户：

# mkdir -v /var/log/clamav

# chown -R amavis.amavis /var/log/clamav

# mkdir -v /var/run/clamav

# chmod 700 /var/run/clamav

# chown -R amavis.amavis /var/run/clamav

建立日志文件

#touch/var/log/clamav/freshclam.log

#chownclamav.clamav/var/log/clamav/freshclam.log

5、配置crontab，让ClamAntiVirus每天凌晨更新新的病毒库：

# crontab -e

添加：

0 0 * * * /usr/local/clamav/bin/freshclam

6、配置库文件搜索路径：

# echo “/usr/local/clamav/lib”>>/etc/ld.so.conf

# ldconfig

7、配置clamav开机自动启动

# echo"/usr/local/clamav/sbin/clamd" >>/etc/rc.local

8、启动

[root@mail bin]# /usr/local/clamav/sbin/clamd

如果出现在启动clamav时如下错误，则是clamav对应的库share文件没有clamav权限所致

root@mail local]# /usr/local/clamav/sbin/clamd

LibClamAV Error: cli_loaddb(): No supported database files found in/usr/local/clamav/share

十七、安装SpamAssassin-3.3.1

1、依赖关系的解决，安装Spamassassin需要很多perl模块的支持，以下是所需模块列表及安装方法；必须的软件包：

Digest::SHA1

HTML::Parser

Net::DNS

LWP (akalibwww-perl)

HTTP::Date

IO::Zlib

Archive::Tar

安装完毕最好在检查一下

cpan>install Digest::SHA1

Digest::SHA1is up to date.

cpan>install HTML::Parser

HTML::Parseris up to date.

cpan>install Net::DNS

Net::DNS isup to date.

cpan>install LWP

LWP is up todate.

cpan>install HTTP::Date

HTTP::Dateis up to date.

cpan>install IO::Zlib

IO::Zlib isup to date.

cpan> installArchive::Tar

Archive::Taris up to date.

说明都已经安装完毕了

可选的软件包，其中有些后面的amavisd也有可能会用到:

MIME::Base64

DB_File

Net::SMTP

Mail::SPF

//安装不成功要手动安装

Cannot chdir() back to/root/.cpan/build/Mail-SPF-v2.9.0: No such file or directory at Makefile.PLline 26.

Running make test

Make had someproblems, maybe interrupted? Won't test

Running make install

Make had someproblems, maybe interrupted? Won't install

IP::Country::Fast

Net::Ident

IO::Socket::INET6

IO::Socket::SSL

Compress::Zlib

Time::HiRes

Mail::DKIM

Mail::DomainKeys

DBI *and* DBD driver/modules

Encode::Detect

Apache::Test

Razor2

推荐使用CPAN自动安装（你的主机要能连上Internet），它能够自动下载安装，并能解决安装过程中的依赖关系。您可以使用类同的以下的命令来进行安装:

#perl -MCPAN-e shell

cpan>install Digest::SHA1

………………

如果您的主机无法直接连接到Internet，您也可以到http://search.cpan.org上搜索下载所需要的软件包，而后使用类同的下列命令安装：

#tar zxvf 软件包.tar.gz

#cd 软件包

#perlMakefile.PL

#make

#make test

#makeinstall

说明：某些软件包安装的过程中可能需要已经列出的其它软件包的支持（可以先尝试安装Spamassassin,然后按提示补充所需软件包），请安照提示自行调整安装顺序。另外，其中有个软件包安装过程中可能要求声明环境变量LC_ALL，此时，可输入如下命令，并重新进行软件包的编译安装即可。

#exportLC_ALL=C

[[email protected]]# tar jxvf

3、测试spamassassin，进入到原代码包

[root@mail Mail-SpamAssassin-3.3.1]# pwd

/usr/local/src/installpack/Mail-SpamAssassin-3.3.1

[root@mail Mail-SpamAssassin-3.3.1]#spamassassin -t < sample-nonspam.txt > nonspam.out

config: no rules were found!Do you need to run 'sa-update'? at/usr/bin/spamassassin line 403

如果出现：

config:!?no rules were found Do you need to run 'sa-update' at / usr / bin /spamassassin line 403.

解决方法：

yum-y install gnupg

或者

wgetftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.10.tar.gz

#tarxvfz gnupg-1.4.10.tar.gz

#cdgnupg-1.4.10

#./configure&& make

#sudomake install

#sudosa-update

我这里已经安装了gnupg 使用下面的命令即可

[[email protected]]# sa-update

[[email protected]]# spamassassin -t < sample-nonspam.txt >nonspam.out

Oct4 14:39:10.292 [13606] warn: config: created user preferences file:

/root/.spamassassin/user_prefs

[root@mail Mail-SpamAssassin-3.3.1]#spamassassin -t < sample-spam.txt > spam.out

4、查看测试结果：

#less nonspam.out

#less spam.out

5、检查配置文件

#spamassassin -d --lint

如果出现下面的问题[root@mail spamassassin]# spamassassin-d --lint

Oct4 14:57:06.388 [13662] warn: config: failedto parse line, skipping, in

"/etc/mail/spamassassin/local.cf":rewrite_subject 1

把上面的rewrite_subject 1注释掉

正常时无任何信息输出

# spamassassin -d --lint

6、启动进程，并将其加入到自动启动队列

#/usr/bin/spamd -d

#echo "/usr/bin/spamd -d">> /etc/rc.local

7、启动进程，并将其加入到自动启动队列

#/usr/bin/spamd -d

#echo "/usr/bin/spamd -d">> /etc/rc.loca

十八、安装amavisd-newhttp://www.amavis.org/下载

1、依赖关系的解决

以下为官方声明所必须的软件包列表，使用perl -MCPAN -e shell进行安装

Archive::Zip

Compress::Zlib

Convert::TNEF

Convert::UUlib

MIME::Base64

MIME::Parser

Mail::Internet

Net::Server

Digest::MD5

IO::Stringy

Time::HiRes

Unix::Syslog

BerkeleyDB

有些可能在上面已经安装，但是为了保险起见，还是建议逐个验证一遍。

如果有安装不上的可以手动下载安装：

发现只有一个Net::Server安装不了

[root@mail model]# tar zxvf Net-Server-2.007.tar.gz-C ../../installpack/

[root@mail model]# cd ../../installpack/

[root@mail installpack]# cdNet-Server-2.007/

[root@mail Net-Server-2.007]# make

[root@mail Net-Server-2.007]# make install

cpan> install Net::Server

Net::Server is up to date.

所有的模块都安装完毕

2、创建运行时目录，并赋予amavis用户（前文中所建）

# mkdir -pv /var/amavis/{tmp,var,db,home}

# chown -R amavis:amavis /var/amavis

#chmod -R 750 /var/amavis

3、安装amavisd-new-2.6.6

[root@mail sourcepack]# tar -zxvfamavisd-new-2.6.6.tar.gz -C ../installpack/

[root@mail sourcepack]# cd ../installpack/

[root@mail installpack]# cdamavisd-new-2.6.6/

拷贝服务端至$PATH中指定的目录，推荐拷贝至/usr/local/sbin：

[root@mail amavisd-new-2.6.6]# cp amavisd/usr/local/sbin/

[root@mail amavisd-new-2.6.6]# chown root/usr/local/sbin/amavisd

[root@mail amavisd-new-2.6.6]# chmod 755/usr/local/sbin/amavisd

拷贝主配置文件至/etc，并修改相应的权限：

# cp amavisd.conf /etc/

# chown root /etc/amavisd.conf

# chmod 644 /etc/amavisd.conf

创建amavisd运行中所需要的隔离区域：

# mkdir /var/virusmails

# chown amavis:amavis /var/virusmails

# chmod 750 /var/virusmails

4、编辑主配置文件

#vi /etc/amavisd.conf

确保您的如下选项的值如下文所示：

$daemon_user= 'amavis';

$daemon_group = 'amavis';

$mydomain = 'test.com'; (此处可更改为自己的DNS域)

$virus_admin="postmaster/@$mydomain";

$mailfrom_notify_admin= "postmaster/@$mydomain";

$mailfrom_notify_recip= "postmaster/@$mydomain";

$mailfrom_notify_spamadmin ="postmaster/@$mydomain";

$mailfrom_to_quarantine = '';

virus_admin_maps =>["postmaster/@$mydomain"] (指定报告病毒和垃圾邮件时发送系统邮件的用户身份)

spam_admin_maps=> ["postmaster/@$mydomain"]

启用ClamAV,(大概在第363行)去掉如下行前的注释符:

#['ClamAV-clamd',

#/&ask_daemon, ["CONTSCAN {}/n", "/var/run/clamav/clamd"],

# qr//bOK$/, qr//bFOUND$/,

#qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

#['Mail::ClamAV', /&ask_clamav, "*", [0], [1],qr/^INFECTED: (.+)/],---在375行

并将如上行中的/var/run/clamav/clamd修改为:/var/run/clamav/clamd.socket

5、测试启动

[root@mail amavisd-new-2.6.6]#/usr/local/sbin/amavisd

遇到错误

fetch_modules:error loading optional module MIME/Decoder/BinHex.pm:

Can't locate Convert/BinHex.pm in @INC (@INCcontains:

[root@mail installpack]# cdConvert-BinHex-1.119/

#perl Makefile.PL

#make

#make install

[root@mail Convert-BinHex-1.119]#/usr/local/sbin/amavisd

The amavisd daemon is already running, PID:[16590]

十九、配置postfix，让它能调用amavisd，以实现病毒及垃圾邮件的过滤

1、配置/etc/postfix/master.cf

#vi /etc/postfix/master.cf

在文末添加如下内容：

#==========================================================================

# service typeprivate unprivchrootwakeupmaxproc command + args

#(yes) (yes) (yes) (never) (100)

# ==========================================================================

#

amavisfeed unix --n-2smtp

-o smtp_data_done_timeout=1200

-o smtp_send_xforward_command=yes

-o disable_dns_lookups=yes

-o max_use=20

#

-o content_filter=

-o smtpd_delay_reject=no

-osmtpd_client_restrictions=permit_mynetworks,reject

-o smtpd_helo_restrictions=

-o smtpd_sender_restrictions=

-osmtpd_recipient_restrictions=permit_mynetworks,reject

-o smtpd_data_restrictions=reject_unauth_pipelining

-o smtpd_end_of_data_restrictions=

-o smtpd_restriction_classes=

-o mynetworks=127.0.0.0/8,192.168.0.0/16

-o smtpd_error_sleep_time=0

-o smtpd_soft_error_limit=1001

-o smtpd_hard_error_limit=1000

-o smtpd_client_connection_count_limit=0

-o smtpd_client_connection_rate_limit=0

-oeceive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_milters

-o local_header_rewrite_clients=

说明：注意每行“-o”前的空格；

2、修改/etc/postfix/main.cf

#vi /etc/postfix/main.cf

在文末添加如下行：

content_filter=amavisfeed:[127.0.0.1]:10024

3、让postfix重新加载主配置文件，并查看启动情况

# postfix reload && tail -f/var/log/maillog

Oct4 16:42:59 mail postfix/postfix-script[16730]: refreshing the Postfixmail system

Oct4 16:42:59 mail postfix/master[3106]: reload -- version 2.8.15,configuration /etc/postfix

4、查看amavisd是否在监听10024端口，并测试服务启动情况：

[root@mail etc]# netstat -anlt |grep10024

tcp00 127.0.0.1:100240.0.0.0:*LISTEN

[root@mail etc]# telnet localhost 10024

Trying 127.0.0.1...

Connected to localhost.localdomain(127.0.0.1).

Escape character is '^]'.

220 [127.0.0.1] ESMTP amavisd-new serviceready

ehlo localhost

250 XFORWARD NAME ADDR PORT PROTO HELOSOURCE

quit

221 2.0.0 [127.0.0.1] amavisd-new closingtransmission channel

Connection closed by foreign host.

5、postfix重新加载配置文件后将授权并激活"127.0.0.1:10025"端口，一个正常的服务连接应该类同下面所示：

[root@mail etc]# telnet localhost 10025

Trying 127.0.0.1...

Connected to localhost.localdomain(127.0.0.1).

Escape character is '^]'.

220 mail.beijihu.com ESMTP Postfix (2.8.15)

ehlo localhost

250-AUTH=PLAIN LOGIN

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

quit

221 2.0.0 Bye

Connection closed by foreign host

6、通过amavisd测试发信

[root@mail ~]# telnet localhost 10024

Trying 127.0.0.1...

Connected to localhost.localdomain(127.0.0.1).

Escape character is '^]'.

220 [127.0.0.1] ESMTP amavisd-new serviceready
