RHEL5+postfix+mysql+extmai（源代碼）

RHEL5+postfix+mysql+extmai（源代碼）配置一個postfix郵件系統，遠比我先前的想象複雜。這次共配置2個postfix系統，花了不少精力，其間也經歷不少麻煩，還好，最後都做成了！在配置過程中，參考了《postfix權威指南》和網上其他人寫的文章，但在實際的配置中，完全按照這些文檔還是不易順利完成。現在此行文披露我做這個事情的全部過程，（在這還要多感謝老朱同志幫助經過我們半個月的努力才搞定的）希望對大家的工作有所幫助。還希望大家多多提寶貴意見！！ *運行環境RHEL5 本機IP爲：172.16.17.86/16 自己爲DNS服務器郵件服務器爲本機名稱爲：mail.test.com

一、（1）配置rhel5的yum服務以方便安裝常用軟件

#service iptables stop

#chkconfig iptables off

#mkdir /media/cdrom

#mount /dev/cdrom /media/cdrom

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

修改爲以下內容：

[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）安裝開發工具

#yum install gcc*

二、安裝配置dns（bind）服務器

#yum install bind caching-nameserver bind-chroot

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

# vim /etc/named.conf

直接分別執行下面兩個末行模式命令：

:%s/127.0.0.1/any/g

:%s/localhost/any/g

保存退出

# vim /etc/named.rfc1912.zones

文件末尾加入以下內容：

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

刪除最下面兩行寫入下面兩行：

@ 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

刪除最下面一行，寫入下面內容：

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

驗證解析

# 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

四、安裝mysql服務器（用數據庫存儲用戶信息）

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

mysql>quit

配置庫文件搜索路徑

# echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
# ldconfig -v
添加/usr/local/mysql/bin到環境變量PATH中
#export PATH=$PATH:/usr/local/mysql/bin
#ln -sv /usr/local/mysql/bin/* /usr/bin/
#service mysqld restart

[f1]使用root用戶連接mysql數據庫默認密碼爲空

[f2]本地root密碼

[f3]讓root用戶通過3066端口連到數據庫讓root用戶通過3066端口連到數據庫

五、安裝openssl（基於密碼學的安全開發包）

www.openssl.org

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

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

#yum install zlib-devel

#./config shared zlib

#make

# 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
檢測安裝結果
# openssl version

openSSL 0.9.8h 28 May 2008

六、安裝ssl（安全套接層協議）

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

啓動測試

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

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

0: OK "Success."

配置庫文件搜索路徑

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

配置開機啓動

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

[f1]本地root密碼

七、安裝db庫（嵌入式數據庫系統）

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

修改相應文件指向

# 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

配置庫文件搜索路徑

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

八、安裝httpd（Web方式管理郵件）

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、安裝php（Php 解釋器，與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

修改以下內容（大約351行，添加後面兩行，針對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，將index.html改爲index.php）

DirectoryIndex index.php

</IfModule>

（147行，修改默認網站目錄）

DocumentRoot "/var/www"

（174行，修改默認目錄）

#mkdir –p /var/www

#echo "<? phpinfo(); ?>" > /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

客戶端直接使用瀏覽器輸入地址瀏覽即可（http://172.16.17.86）

[f1]和selinux有關，需要下面命令修改庫文件類型

十、安裝postfix（郵件帳號後臺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]

生成別名二進制文件，這個步驟如果忽略，會造成postfix效率極低：
# mv /etc/aliases /etc/aliases.OFF
#ln -sv /etc/postfix/aliases /etc/aliases
#newaliases

#vim /etc/postfix/main.cf
修改以下幾項爲您需要的配置
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

說明:
myorigin參數用來指明發件人所在的域名；
mydestination參數指定postfix接收郵件時收件人的域名，即您的postfix系統要接收到哪個域名的郵件；
myhostname 參數指定運行postfix郵件系統的主機的主機名，默認情況下，其值被設定爲本地機器名；
mydomain參數指定您的域名，默認情況下，postfix將myhostname的第一部分刪除而作爲mydomain的值；
mynetworks 參數指定你所在的網絡的網絡地址，postfix系統根據其值來區別用戶是遠程的還是本地的，如果是本地網絡用戶則允許其訪問；
inet_interfaces 參數指定postfix系統監聽的網絡接口；
注意：
1、在postfix的配置文件中，參數行和註釋行是不能處在同一行中的；
2、任何一個參數的值都不需要加引號，否則，引號將會被當作參數值的一部分來使用；
3、每修改參數及其值後執行 postfix reload 即可令其生效；但若修改了inet_interfaces，則需重新啓動postfix；
4、如果一個參數的值有多個，可以將它們放在不同的行中，只需要在其後的每個行前多置一個空格即可；postfix會把第一個字符爲空格或tab的文本行視爲上一行的延續；

啓動postfix

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

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

#useradd test

# telnet localhost 25

Trying 127.0.0.1...

十一、爲postfix開啓基於cyrus-sasl的認證

使用以下命令驗正postfix是否支持cyrus風格的sasl認證，如果您的輸出爲以下結果，則是支持的

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

cyrus

dovecot

#vim /etc/postfix/main.cf
最下面添加以下內容：

############################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
添加如下內容：
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN

讓postfix重新加載配置文件

# /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-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN

[f1] 250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

[f1]有這兩行輸出即可

十二、讓postfix支持虛擬域和虛擬用戶

#vim /etc/postfix/main.cf

文件最後添加以下內容：

########################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

寫入以下內容：

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

#vim /etc/postfix/mysql_virtual_domains_maps.cf

添加以下內容：
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

寫入以下內容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username

#vim /etc/postfix/mysql_virtual_mailbox_maps.cf

寫入以下內容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username

這裏用到的數據庫及用戶的建立可以後文中的extmail說明部分來實現，您可以參照那一部分來理解這裏指定的數據庫及其用戶名等

十三、安裝courier-authlib（用於sasl用戶密碼的認證）

www.courier-mta.org/authlib/

#yum install gdbm-devel

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