4、系统安装

操作系统采用debian 3.1(sarge),下面没有独立安装的gcc,make,db,glibc等基本库和软件，邮件系统需要的全部用　apt-get install 包名称　来安装

　　mail~#apt-get install gcc make

　　mail~#apt-get install libdb4-*

　　mail~#apt-get install curses*

　　mail~#apt-get install termcap*

..............

4.1、mysql

mail~#wget http://dev.mysql.com/get/Downloads/MySQL-4.1/mysql-4.1.12.tar.gz/from/http://mysql.cbn.net.id/

mail~#groupadd mysql

mail~#useradd -g mysql mysql

mail~#tar zxvf /usr/src/mail/mysql-4.1.12.tar.gz -C /tmp

mail~#cd /tmp/mysql-4.1.12

mail~#./configure --prefix=/opt/mysql --localstatedir=/opt/mysql/data --with-unix-socket-path=/tmp/mysql.sock --with-mysql-user=mysql --with-charset=gb2312 --with-extra-charsets=all

mail~#make

mail~#make install

mail~#chown -R mysql:mysql /opt/mysql/data/

　　如果没有/opt/mysql/var/mail.err，就手动创建一个

mail~#mkdir /opt/mysql/var

mail~#touch /opt/mysql/var/mail.err

mail~#/opt/mysql/bin/mysqld_safe --user=mysql & #起动mysql服务

mail~#/opt/mysql/bin/mysql #起动mysql客户端

mail~#vi /etc/ld.so.conf，添加

　　　　　 /opt/mysql/lib/mysql

mail~#ldconfig

mail~#cp /opt/mysql/share/mysql/mysql.server /etc/init.d/mysqld

mail~#chmod 755 /etc/init.d/mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc3.d/S52mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc5.d/S52mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc0.d/K25mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc1.d/K25mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc2.d/K25mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc4.d/K25mysqld

mail~#ln -s /etc/init.d/mysqld /etc/rc6.d/K25mysqld

4.2、apahce

mail~#wget http://apache.justdn.org/httpd/apache_1.3.33.tar.gz

mail~#goupadd www

mail~#useradd -g www -d /dev/null -s /bin/false www

mail~#tar zxvf /usr/src/mail/apache_1.3.33.tar.gz -C /tmp

mail~#cd /tmp/apache_1.3.33

mail~#./configure --prefix=/opt/apache --enable-module=rewrite --enable-shared=rewrite --enable-module=proxy --enable-shared=proxy --enable-module=so --server-uid=www --server-gid=www

mail~#make

mail~#make install

mail~#/opt/mysql/var# /opt/apache/bin/apachectl start #起动apache服务器

mail~#cd /opt/apache/bin/

mail~#cp apachectl /etc/init.d/httpd

mail~#cd /etc/init.d/

mail~#chmod 755 httpd

mail~#ln -s /etc/init.d/httpd /etc/rc3.d/S51httpd

mail~#ln -s /etc/init.d/httpd /etc/rc5.d/S51httpd

mail~#ln -s /etc/init.d/httpd /etc/rc0.d/K15httpd

mail~#ln -s /etc/init.d/httpd /etc/rc1.d/K15httpd

mail~#ln -s /etc/init.d/httpd /etc/rc2.d/K15httpd

mail~#ln -s /etc/init.d/httpd /etc/rc4.d/K15httpd

mail~#ln -s /etc/init.d/httpd /etc/rc6.d/K15httpd

4.3、php4

mail~#wget http://cn2.php.net/get/php-4.3.11.tar.gz/from/cn.php.net/mirror

mail~#tar zxvf /usr/src/mail/php-4.3.11.tar.gz -C /tmp

mail~#cd /tmp/php-4.3.11

mail~#./configure --prefix=/opt/php4 --with-xml --with-mysql=/opt/mysql --with-mysql-sock=/tmp/mysqld.php4.sock --with-apxs=/opt/apache/bin/apxs

mail~#make

mail~#make install

mail~#cp php.ini-dist /opt/php4/lib/php.ini

　　修改/opt/apache/conf/httpd.conf，添加php4支持,添加内容如下:

#php 4

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

另更改

DirectoryIndex index.html

</IfModule>

为

DirectoryIndex index.html index.php

</IfModule>

　　 mail~#vi /opt/apache/htdocs/test.php,内容如下

<?php

phpinfo();

mail~#/opt/mysql/var# /opt/apache/bin/apachectl restart #重启apache服务器

使用lynx或常用的浏览器如IE、firefox,浏览http://ip/test.php，看到了PHP的信息页面，OK

4.4、openssl

mail~#wget http://www.openssl.org/source/openssl-0.9.8.tar.gz

mail~#tar zxvf /usr/src/mail/openssl-0.9.8.tar.gz -C /tmp

mail~#cd /tmp/openssl-0.9.8

mail~#./configure --prefix=/opt/openssl

mail~#make

mail~#make install

mail~#ln -s /opt/openssl/include/openssl /usr/include/openssl

4.5、cyrus-sasl2

mail~#wget http://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.21.tar.gz

mail~#tar zxvf /usr/src/mail/cyrus-sasl-2.1.21.tar.gz -C /tmp

mail~#cd /tmp/cyrus-sasl-2.1.21

mail~#./configure --prefix=/opt/sasl2 --enable-login --enable-plain --enable-sql --enable-pwcheck --disable-anon --disable-digest --with-mysql=/opt/mysql --with-mysql-includes=/opt/mysql/include/mysql --with-mysql-libs=/opt/mysql/lib/mysql --with-saslauthd=/var/run

mail~#make

　　如果出现下面的错误:

auth_getpwent.c:48:20: des.h: No such file or directory

make[3]: *** [auth_getpwent.o] Error 1

make[3]: Leaving directory `/tmp/cyrus-sasl-2.1.21/saslauthd'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/tmp/cyrus-sasl-2.1.21'

make: *** [all] Error 2

　　修改/tmp/cyrus-sasl-2.1.21/saslauthd/Makefiles内的变量CFLAGS添加-I/opt/openssl/include/openssl

或者直接

mail~#cp /tmp/cyrus-sasl-2.1.21/mac/libdes/public/des.h /tmp/cyrus-sasl-2.1.21/

mail~#make

mail~#make install

mail~#vi /etc/ld.so.conf #添加以下内容

mail~#make install #一路回车默认就可以了

mail~#vi /etc/init.d/postfix

#!/bin/sh

start() {

#Start daemons.

echo -n "Starting postfix: "

/usr/sbin/postfix start

/usr/sbin/postfix reload

}

restart(){

stop

start

}

abort(){
