RHEL5+postfix+mysql+extmai(源代码)
配置一个postfix邮件系统,远比我先前的想象复杂。这次共配置2个postfix系统,花了不少精力,其间也经历不少麻烦,还好,最后都做成了!在配置过程中,参考了《postfix权威指南》和网上其他人写的文章,但在实际的配置中,完全按照这些文档还是不易顺利完成。现在此行文披露我做这个事情的全部过程,(在这还要多感谢老朱同志帮助经过我们半个月的努力才搞定的)希望对大家的工作有所帮助。还希望大家多多提宝贵意见!!
 *运行环境RHEL5
  本机IP为:172.16.17.86/16 自己为DNS服务器 邮件服务器为本机名称为:mail.test.com

一、(1)配置rhel5yum服务以方便安装常用软件

#service iptables stop

#chkconfig iptables off

#mkdir /media/cdrom

#mount /dev/cdrom /media/cdrom

#vim /etc/yum.repos.d/rhel-debuginfo.repo

修改为以下内容:

[rhel-debuginfo]

name=Red Hat Enterprise Linux $releasever - $basearch - Debug

baseurl=file:///media/cdrom/Server

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

2)安装开发工具

       #yum install gcc*

二、      安装配置dnsbind)服务器

#yum install bind caching-nameserver bind-chroot

#cp -a /etc/named.caching-nameserver.conf /etc/named.conf

# vim /etc/named.conf

直接分别执行下面两个末行模式命令:

:%s/127.0.0.1/any/g

:%s/localhost/any/g

保存退出

# vim /etc/named.rfc1912.zones

文件末尾加入以下内容:

 

zone "test.com" IN {

        type master;

        file "test.com.zone";

};

 

zone "16.172.in-addr.arpa" IN {

        type master;

        file "16.172";

};

保存退出

# cp -a /var/named/chroot/var/named/localhost.zone /var/named/chroot/var/named/test.com.zone

#vim /var/named/chroot/var/named/test.com.zone

删除最下面两行写入下面两行:

@                   IN MX 5        mail.test.com.

mail                IN A                     172.16.17.86

保存退出

#cp -a /var/named/chroot/var/named/named.local /var/named/chroot/var/named/16.172

#vim /var/named/chroot/var/named/16.172

删除最下面一行,写入下面内容:

86.17   IN      PTR     mail.test.com.

保存退出

#service named restart

#chkconfig named on

#echo 'nameserver 172.16.17.86' > /etc/resolv.conf

验证解析

# nslookup

> 172.16.17.86

Server:         172.16.17.86

Address:        172.16.17.86#53

 

86.17.16.172.in-addr.arpa       name = mail.test.com.

> mail.test.com

Server:         172.16.17.86

Address:        172.16.17.86#53

 

Name:   mail.test.com

Address: 172.16.17.86

> set type=mx

> test.com

Server:         172.16.17.86

Address:        172.16.17.86#53

 

test.com        mail exchanger = 5 mail.test.com.

>exit

三、

四、安装mysql服务器(用数据库存储用户信息

        http://downloads.mysql.com

#groupadd mysql

#useradd –g mysql –s /bin/false –M mysql

#tar -zxvf mysql-5.0.22.tar.gz -C /usr/local/src/

#cd /usr/local/src/mysql-5.0.22/

#yum install ncurses-devel

#./configure --prefix=/usr/local/mysql --enable-thread-safe-client --enable-local-infile --with-charset=gbk --with-extra-charset=all --with-low-memory

#make

#make install

#cp /usr/local/src/mysql-5.0.22/support-files/my-medium.cnf /etc/my.cnf

#cd /usr/local/mysql
#chown -R mysql:mysql .
#bin/mysql_install_db --user=mysql
#chown -R root .
#chown -R mysql var
#bin/mysqld_safe --user=mysql &

#cd /usr/local/src/mysql-5.0.22/

#cp support-files/mysql.server /etc/rc.d/init.d/mysqld

#chmod 700 /etc/rc.d/init.d/mysqld

#chkconfig --add mysqld

#chkconfig mysqld on

#/usr/local/mysql/bin/mysqladmin ping

mysqld is alive

# /usr/local/mysql/bin/mysqladmin version

配置库文件搜索路径

# echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
# ldconfig -v
添加/usr/local/mysql/bin到环境变量PATH
#export PATH=$PATH:/usr/local/mysql/bin
#ln -sv /usr/local/mysql/bin/* /usr/bin/
#service mysqld restart


 [f1]使用root用户连接mysql数据库默认密码为空

 [f2]本地root密码

 [f3]root用户通过3066端口连到数据库让root用户通过3066端口连到数据库

 

 

五、安装openssl基于密码学的安全开发包

www.openssl.org

#tar -zxvf openssl-0.9.8h.tar.tar -C /usr/local/src/

#cd /usr/local/src/openssl-0.9.8h/

# ln -sv /usr/local/ssl/include/openssl /usr/include/openssl
# ln -sv /usr/local/ssl/lib/libssl.so.0.9.8 /usr/lib/libssl.so

# echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
# ldconfig
# ldconfig -v
检测安装结果
# openssl version

openSSL 0.9.8h 28 May 2008

 

六、安装ssl(安全套接层协议)

     http://www.oracle.com/database/berkeley-db.html

#tar -zxvf cyrus-sasl-2.1.22.tar.tar -C /usr/local/src/

#cd /usr/local/src/cyrus-sasl-2.1.22/

#./configure --prefix=/usr/local/sasl2 --disable-gssapi --disable-anon --disable-sample --disable-digest --enable-plain --enable-login --enable-sql --with-mysql=/usr/local/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket

#cp /usr/local/src/cyrus-sasl-2.1.22/mac/libdes/public/des.h ./

#make

#make install

# mv /usr/lib/libsasl2.so.2.0.22 /usr/lib/libsasl2.so.2.0.22.OFF
# mv /usr/lib/sasl2 /usr/lib/sasl2.OFF

#rm –rf /usr/lib/libsasl2.so.2

#rm -rf /usr/sbin/pluginviewer
# rm -rf /usr/sbin/saslauthd
# rm -rf /usr/sbin/sasldblistusers2
# rm -rf /usr/sbin/saslpasswd2
# rm -rf /usr/sbin/testsaslauthd

# ln -sv /usr/local/sasl2/lib/* /usr/lib

# ln -sv /usr/local/sasl2/lib/* /usr/local/lib
# ln -sv /usr/local/sasl2/include/sasl/* /usr/local/include
# ln -sv /usr/local/sasl2/sbin/* /usr/sbin
# ln -sv /usr/local/sasl2/sbin/* /usr/local/sbin/

# mkdir -pv /var/state/saslauthd

启动测试

# /usr/local/sbin/saslauthd -a shadow pam

# /usr/local/sbin/testsaslauthd -u root -p password[f1] 

0: OK "Success."

配置库文件搜索路径

# echo "/usr/local/sasl2/lib" >> /etc/ld.so.conf
# echo "/usr/local/sasl2/lib/sasl2" >> /etc/ld.so.conf
# ldconfig
# ldconfig -v

配置开机启动

#echo "/usr/local/sbin/saslauthd -a shadow pam">>/etc/rc.local


 [f1]本地root密码

 

七、安装db库(嵌入式数据库系统

http://www.oracle.com/technology/products/berkeley-db/db/index.html

#tar -zxvf db-4.7.25.tar.gz -C /usr/local/src/

#cd /usr/local/src/db-4.7.25/build_unix/

#../dist/configure --prefix=/usr/local/BerkeleyDB
#make
#make install

修改相应文件指向

# ln -sv /usr/local/BerkeleyDB/include /usr/include/db4
# ln -sv /usr/local/BerkeleyDB/include/db.h /usr/include/db.h
# ln -sv /usr/local/BerkeleyDB/include/db_cxx.h /usr/include/db_cxx.h

配置库文件搜索路径

# echo "/usr/local/BerkeleyDB/lib" >> /etc/ld.so.conf
# ldconfig
# ldconfig -v

八、安装httpdWeb方式管理邮件

      http://archive.apache.org/dist/httpd/binaries

#tar jxvf httpd-2.2.4.tar.bz2 -C /usr/local/src/

#cd /usr/local/src/httpd-2.2.4/

#./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-cgi --enable-so --enable-ssl --with-ssl=/usr/local/ssl --enable-track-vars --enable-rewrite --with-zlib --enable-mods-shared=most --enable-suexec --with-suexec-caller=daemon --with-suexec-docroot=/var/www/extsuite/
#make

#make install
#echo "/usr/local/apache/bin/apachectl start" >> /etc/rc.local

 

九、安装phpPhp 解释器,与apache一起使用

        http://www.php.net

 

#tar jxvf php-5.2.5.tar.bz2 –C /usr/local/src

# mkdir -p /usr/local/php
# cd /usr/local/src/php-5.2.5
#./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-zlib
#make
#make install
#cp php.ini-dist /usr/local/php/lib/php.ini

#vim /etc/httpd/httpd.conf

修改以下内容(大约351行,添加后面两行,针对php支持)

AddType application/x-compress .Z

AddType application/x-gzip .gz .tgz

AddType application/x-httpd-php .php

AddType application/x-httpd-source .phps

209行,将index.html改为index.php

     DirectoryIndex index.php

147行,修改默认网站目录)

DocumentRoot "/var/www"

174行,修改默认目录)

#mkdir –p /var/www

#echo "" > /var/www/index.php

# /usr/local/apache/bin/apachectl restart

httpd: Syntax error on line 99 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied[f1] 

#chcon -t texrel_shlib_t /usr/local/apache/modules/libphp5.so

客户端直接使用浏览器输入地址浏览即可(http://172.16.17.86

 


 [f1]selinux有关,需要下面命令修改库文件类型

十、安装postfix邮件帐号后台web管理工具

   ftp://postfix.cn99.com/postfix/index.html

#groupadd -g 2525 postfix
#useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
#groupadd -g 2526 postdrop
#useradd -g postdrop -u 2526 -s /bin/false -M postdrop

#tar zxvf postfix-2.6-20080824.tar.gz -C /usr/local/src/

#cd /usr/local/src/postfix-2.6-20080824/

#make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -I/usr/local/BerkeleyDB/include-DUSE_TLS -I/usr/local/ssl/include/openssl ' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/BerkeleyDB/lib -L/usr/local/ssl/lib -lssl -lcrypto'

#make

#cp /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/lib[f1] 

#make install

install_root: [/]
tempdir: [/soft// postfix-2.4.5]
/tmp
config_directory: [/etc/postfix]

command_directory: [/usr/sbin]
/usr/local/postfix/sbin
daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec
data_directory: [/var/lib/postfix]
  
html_directory: [no]
/var/www/postfix_html  

mail_owner: [postfix]

mailq_path: [/usr/bin/mailq]

manpages: [/usr/local/man] /usr/local/postfix/man

newaliases_path: [/usr/bin/newaliases]

queue_directory: [/var/spool/postfix]

readme_directory: [no]
sendmail_path: [/usr/sbin/sendmail]
setgid_group: [postdrop]

生成别名二进制文件,这个步骤如果忽略,会造成postfix效率极低:
# mv /etc/aliases /etc/aliases.OFF
#ln -sv /etc/postfix/aliases /etc/aliases
#newaliases


#vim /etc/postfix/main.cf

修改以下几项为您需要的配置
myhostname = mail.test.com

myorigin = test.com
mydomain = test.com
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 172.16.0.0/16, 127.0.0.0/8

说明:
myorigin
参数用来指明发件人所在的域名;
mydestination
参数指定postfix接收邮件时收件人的域名,即您的postfix系统要接收到哪个域名的邮件;
myhostname
参数指定运行postfix邮件系统的主机的主机名,默认情况下,其值被设定为本地机器名;
mydomain
参数指定您的域名,默认情况下,postfixmyhostname的第一部分删除而作为mydomain的值;
mynetworks
参数指定你所在的网络的网络地址,postfix系统根据其值来区别用户是远程的还是本地的,如果是本地网络用户则允许其访问;
inet_interfaces
参数指定postfix系统监听的网络接口;
注意:
1
、在postfix的配置文件中,参数行和注释行是不能处在同一行中的;
2
、任何一个参数的值都不需要加引号,否则,引号将会被当作参数值的一部分来使用;
3
、每修改参数及其值后执行 postfix reload 即可令其生效;但若修改了inet_interfaces,则需重新启动postfix
4
、如果一个参数的值有多个,可以将它们放在不同的行中,只需要在其后的每个行前多置一个空格即可;postfix会把第一个字符为空格或tab的文本行视为上一行的延续;

 

启动postfix

# /usr/local/postfix/sbin/postfix start

#echo  '/usr/local/postfix/sbin/postfix start' >> /etc/rc.local

#useradd test

# telnet localhost 25

 [f1]如果配置没有提示需要拷贝该库文件到指定位置

 

十一、为postfix开启基于cyrus-sasl的认证

 

使用以下命令验正postfix是否支持cyrus风格的sasl认证,如果您的输出为以下结果,则是支持的

# /usr/local/postfix/sbin/postconf -a

cyrus

dovecot

#vim /etc/postfix/main.cf
最下面添加以下内容:

############################CYRUS-SASL############################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_sasl_application_name = smtpd
smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!


#vim /usr/local/lib/sasl2/smtpd.conf
添加如下内容:
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN

postfix重新加载配置文件

# /usr/local/postfix/sbin/postfix reload

# telnet localhost 25

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

220 Welcome to our mail.test.com ESMTP,Warning: Version not Available!

250-mail.test.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN

[f1] 250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN


 [f1]有这两行输出即可

十二、postfix支持虚拟域和虚拟用户

 

#vim /etc/postfix/main.cf

文件最后添加以下内容:

########################Virtual Mailbox Settings########################
virtual_mailbox_base = /var/mailbox/
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_uid_maps = static:2525
virtual_gid_maps = static:2525
virtual_transport = virtual
maildrop_destination_recipient_limit = 1
maildrop_destination_concurrency_limit = 1
##########################QUOTA Settings########################
message_size_limit = 14336000
virtual_mailbox_limit = 20971520
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please Tidy your mailbox and try again later.
virtual_overquota_bounce = yes

# vim /etc/postfix/mysql_virtual_alias_maps.cf

 

写入以下内容:

user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address

 

#vim /etc/postfix/mysql_virtual_domains_maps.cf

添加以下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain

 

#vim /etc/postfix/mysql_virtual_mailbox_limit_maps.cf

写入以下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username


#vim /etc/postfix/mysql_virtual_mailbox_maps.cf

写入以下内容:
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username

这里用到的数据库及用户的建立可以后文中的extmail说明部分来实现,您可以参照那一部分来理解这里指定的数据库及其用户名等

 

十三、安装courier-authlib用于sasl用户密码的认证

      www.courier-mta.org/authlib/

#yum install gdbm-devel

#tar zxvf courier-authlib_0.61.0.orig.tar.gz -C /usr/local/src/
