一、简介:
本文以最简单,最方便的方法在centos 5.2 上安装一个全功能的邮件系统,此文适合REDHAT所有系列,在文中,能用RPM 安装的,我们将采用rpm 安装,如果rpm没有的,我们将创建自己的rpm。部分软件简介:
1、AMP ---apache(web服务) 、mysql(数据库)、php(非必需) 的简称
2、postfix --mta 邮件系统核心
3、courier-authlib--一个为courier-imap,maildrop,sasl2 提供用户信息的后台进程序
4、courier-imap --提供pop3,pop3s,imap,imaps 服务的程序
5、amavisd-new --提供内容过滤
6、clamav -- 著名的杀毒软件
7、extmail --一个著名的webmail程序
8、extman --与extmail集成的后台管理程序
9、slockd --一个基于smtp阶段的反垃圾邮件程序
10、vhmgr --由本文作者编写,用于管理apache,ftp,mysql 的虚拟主机管理程序。
安装环境:
centos 5.2
域名机器名:mail.yiyou.org mail.icaot.com
域名:yiyou.org icaot.com
二、安装系统
安装系统时,选择“customize software selection”(自定义安装),在package group selection 对话框里选择:
其它不选择。
在setup agnet(或进入系统后运行setup) 里选择firewall configuration
将security level 与SELinux
改为disabled,目的是为了避免在安装调试时产生不必要的麻烦,在系统安装完成后,可以自己去调试安全部分,在这里将不作详细介绍。
配置yum,在本文中使用的是网通线路,所以选择了 作为安装镜像。
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# wget CentOS-Base.repo.ta139
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@localhost yum.repos.d]# mv CentOS-Base.repo.ta139 CentOS-Base.repo
三、安装软件
1、安装AMP
[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql
修改启动配置并启动
[root@localhost ~]# chkconfig --level 345 mysqld on
[root@localhost ~]# chkconfig --level 345 httpd on
[root@localhost ~]# service mysqld start
[root@localhost ~]# service httpd start
2、安装phpmyadmin
注意:可以选择自己需要的版本 我没有安装phpmyadmin
[root@localhost ~]# wget
[root@localhost ~]# tar xjf phpMyAdmin-2.11.9-all-languages-utf-8-only.tar.bz2
[root@localhost ~]# mv phpMyAdmin-2.11.9-all-languages-utf-8-only /var/www/html/phpmyadmin
[root@localhost phpmyadmin]# cp config.sample.inc.php config.inc.php
编辑config.inc.php 改为下面,字符串是任意的。 $cfg['blowfish_secret'] = 'skssiwksksie'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
进入phpmyadmin 请马上修改mysql root 用户的密码。
3、导入extman 后台数据库
将extmail/extman/slockd 上传到服务器,可以使用ftp/winscp 上传
[root@localhost ~]# tar zxf extman-0.2.5b1.tar.gz
[root@localhost ~]# cd extman-0.2.5b1/docs/
[root@localhost docs]# mysql -uroot -p
如何使用了phpmyadmin改了root 密码,记得输入密码,如果密码为空,请按回车。
4、RPM 简介
下面我们将采用rpm 的方式安装软件
/usr/src/redhat/SPEC spec 文件夹,通常是rpm文件夹
/usr/src/redhat/RPMS 是生成rpm 的文件,下面还有i368,i486 等子文件夹,一般我们用i386 架构
/usr/src/redhat/SOURCE 源文件文件夹
为了安装时切换目录的方便,我们将目录存放到一个shell变量里。
[root@localhost ~]# export RPMS=/usr/src/redhat/RPMS
[root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES
[root@localhost ~]# export SPEC=/usr/src/redhat/SPECS
在下面安装过程中,大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的,只是shell变量的替换。
5、安装authlib
A、安装依懒的包[root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel
[root@localhost ~]# wget
[root@localhost ~]# tar xjf courier-authlib-0.61.0.tar.bz2
[root@localhost ~]# cd courier-authlib-0.61.0
[root@localhost courier-authlib-0.61.0]# cp courier-authlib.spec $SPEC
[root@localhost courier-authlib-0.61.0]# cd ..
[root@localhost ~]# cp courier-authlib-0.61.0.tar.bz2 $SOURCE
[root@localhost ~]# cd $SPEC
[root@localhost SPECS]# rpmbuild -bb courier-authlib.spec (创建rpm文件)
B、安装生成的rpm[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh courier-authlib-0.61.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-devel-0.61.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-mysql-0.61.0-1.i386.rpm
C、配置authlibdaemon[root@localhost i386]# cd /etc/authlib/
[root@localhost authlib]# mv authdaemonrc authdaemonrc.bak
[root@localhost authlib]# vim authdaemonrc
输入下面的内容: authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
authdaemonvar=/var/spool/authdaemon
DEBUG_LOGIN=2
DEFAULTOPTIONS="wbnodsn=1"
LOGGEROPTS=""
D、配置authmysqlrc [root@localhost authlib]# mv authmysqlrc authmysqlrc.bak
[root@localhost authlib]# vim authmysqlrc
输入下面的内容: MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_PORT 0
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\
CONCAT('/home/data/domains/',homedir), \
CONCAT('/home/data/domains/',maildir), \
quota, \
name \
FROM mailbox \
WHERE username = '$(local_part)@$(domain)'
E、启动authlib[root@localhost ~]# service courier-authlib start
Starting Courier authentication services: authdaemond
[root@localhost ~]# chmod 777 /var/spool/authdaemon/
6、安装courier-imap
由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户,并创建一个rpm环境
[root@localhost ~]# useradd yiyou 在这里添加自己的用户
软件包依懒需要安装openldap-server,rpm创建完成后可以删除
[root@localhost ~]# yum -y install openldap-servers
[root@localhost ~]# su - yiyou [yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
[yiyou@localhost ~]$ vim ~/.rpmmacros
输入内容: %_topdir /home/yiyou/rpm
[yiyou@localhost ~]$ wget
[yiyou@localhost ~]$ cp courier-imap-4.4.1.tar.bz2 rpm/SOURCES/
[yiyou@localhost ~]$ tar xjf courier-imap-4.4.1.tar.bz2
[yiyou@localhost ~]$ cd courier-imap-4.4.1
[yiyou@localhost courier-imap-4.4.1]$ cp courier-imap.spec ../rpm/SPECS/
[yiyou@localhost courier-imap-4.4.1]$ cd ../rpm/SPECS/
编辑courier-imap.spec 将下面的内容: %if %suse_version
BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)
%else
BuildPreReq: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers
%endif
改为:
%if %suse_version 在这里好像提示没有安装openldap-server yum install openldap* 还真没装
BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel
%else
BuildPreReq: rpm >= 4.0.2 sed openldap-devel openldap-servers
%endif
创建rpm [yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec
完成rpm后,输入exit退出当前用户。
[root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.4.1-1.i386.rpm
[root@localhost ~]# service courier-imap start
7、安装cyrus-sasl
A、安装SRPM[root@localhost ~]# wget ftp://194.199.20.114/linux/fedora/updates/8/SRPMS/cyrus-sasl-2.1.22-8.fc8.src.rpm
[root@localhost ~]# rpm -ivh cyrus-sasl-2.1.22-8.fc8.src.rpm
[root@localhost ~]# cd $SPEC
编辑cyrus-sasl.spec 将下面:
# Bundling copy of Berkeley DB, for sasldb support.
topdir=`pwd`
pushd db-%{db_version}/build_unix
../dist/configure \
--with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic \
--with-uniquename=_cyrus_sasl_sasldb_rh \
--prefix=${topdir}/db-instroot \
--includedir=${topdir}/db-instroot/include \
--libdir=${topdir}/db-instroot/lib
改为:
# Bundling copy of Berkeley DB, for sasldb support.
topdir=`pwd`
pushd db-%{db_version}/build_unix
../dist/configure \
--with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic \
--with-uniquename=_cyrus_sasl_sasldb_rh \
--prefix=${topdir}/db-instroot \
--includedir=${topdir}/db-instroot/include \
--libdir=${topdir}/db-instroot/lib \
--with-authdaemond=/var/spool/authdaemon提示下面的故障的请看上面--with-authdaemond=/var/spool/authdaemon: No such file or directory 少了各斜杠所以看不到这个选项Cannot enable LDAPDB plugin: Could not locate OpenLDAP因为没有安装oepnldap 客户端什么的。装上就行了
B、生成rpm[root@localhost SPECS]# rpmbuild -bb cyrus-sasl.spec
[root@localhost RPMS]# cd $RPMS/i386
[root@localhost i386]# rpm -e --nodeps cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib (如果这些包存在)
[root@localhost i386]# rpm -ihv cyrus-sasl-lib-2.1.22-8.i386.rpm
[root@localhost i386]# rpm -ihv cyrus-sasl-2.1.22-8.i386.rpm
[root@localhost i386]# rpm -ihv cyrus-sasl-plain-2.1.22-8.i386.rpm
C、配置sasl2
创建/usr/lib/sasl2/smtpd.conf 文件,输入下面的内容: pwcheck_method:authdaemond
log_level:3
mech_list:PLAIN LOGIN
authdaemond_path:/var/spool/authdaemon/socket
8、安装postfix
A、下载软件包[root@localhost i386]# cd
[root@localhost ~]# wget
[root@localhost ~]# rpm -ivh postfix-2.5.4-2.src.rpm
[root@localhost ~]# cd $SPEC
编辑postfix.spec 修改下面的选项 %define distribution rhel-5.0
%define with_mysql_redhat 1
%define with_sasl 2
%define with_vda 1
B、创建rpm [root@localhost SPECS]# rpmbuild -bb postfix.spec
[root@localhost RPMS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh postfix-2.5.4-2.rhel4.i386.rpm
C、切换mta [root@localhost i386]# alternatives --config mta (选择2,postfix)
[root@localhost i386]# rpm -e sendmail
[root@localhost i386]# cd /usr/sbin/
[root@localhost sbin]# mv sendmail sendmail.bak
[root@localhost sbin]# newaliases
[root@localhost sbin]# ln -s sendmail.postfix sendmail
D、配置postfix [root@localhost ~]# cd /etc/postfix/
[root@localhost postfix]# mv main.cf main.cf.bak
[root@localhost postfix]# vim main.cf
输入下面的内容: queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
unknown_local_recipient_reject_code = 550
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = /usr/share/doc/postfix-2.5.2-documentation/html
manpage_directory = /usr/share/man
sample_directory = /etc/postfix
readme_directory = /usr/share/doc/postfix-2.5.2-documentation/readme
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
myhostname = mail.yiyou.org
mydomain = yiyou.org
mydestination = $myhostname
smtpd_banner = yiyou.org ESMTP Mail System
message_size_limit = 14680064
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_base = /home/data/domains
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf
virtual_transport = maildrop:
maildrop_destination_recipient_limit = 1
#sasl
smtpd_sasl_auth_enable = yes

broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
reject_unauth_pipelining,
reject_invalid_hostname
复制extman/docs 目录的cf 文件到/etc/postfix [root@localhost postfix]# cp /root/extman-0.2.5b1/docs/mysql_virtual_* .
因为配置文件的用户、密码与数据库时一样,所以不用修改。 [root@localhost postfix]# service postfix start
9、安装maildrop
A、下载生成RPM[root@localhost postfix]# cd
[root@localhost ~]# wget
[root@localhost ~]# cp maildrop-2.0.4.tar.bz2 $SOURCE
[root@localhost ~]# tar xjf maildrop-2.0.4.tar.bz2
[root@localhost ~]# cd maildrop-2.0.4
[root@localhost maildrop-2.0.4]# cp maildrop.spec $SPEC
[root@localhost maildrop-2.0.4]# cd $SPEC
编辑maildrop.spec 把下面: BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel
改为: BuildRequires: gdbm-devel pcre-devel
把下面: %configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 \
--enable-sendmail=/usr/sbin/sendmail
改为: %configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \
--enable-authlib
B、创建安装maildrop rpm [root@localhost SPECS]# yum -y install pcre-devel
[root@localhost SPECS]# rpmbuild -bb maildrop.spec
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh maildrop-2.0.4-1.i386.rpm
C、添加虚似用户及创建目录 [root@localhost i386]# cd 在这里提示已经添加了用户 应该是安装postfix的时候创建的用户
[root@localhost ~]# groupadd -g 1000 vgroup
[root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser
编辑/etc/postfix/master.cf ,加入下面的内容: maildrop unix - n n - - pipe
flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
D、创建邮件存储目录 [root@localhost ~]# mkdir -p /home/data/domains/extmail.org/postmaster
[root@localhost ~]# maildirmake /home/data/domains/extmail.org/postmaster/Maildir
[root@localhost ~]# chown -R vuser:vgroup /home/data/domains/
E、测试maildrop [root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@extmail.org
maildrop: authlib: groupid=1000
maildrop: authlib: userid=1000 这里改成自己相应的
maildrop: authlib:
[email=logname=postmaster@extmail.org]logname=postmaster@extmail.org[/email]
,home=/home/data/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/
maildrop: Changing to /home/data/domains/extmail.org/postmaster
Message start at 0 bytes, envelope sender=postmaster@extmail.org
maildrop: Attempting .mailfilter
maildrop: Delivery complete.
出现上以信息说明authlib,maildrop 工作正常
F、测试pop3[root@localhost ~]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Hello there.

baseurl=
gpgcheck=1
enabled=1
gpgkey=
[root@localhost ~]# yum -y install clamav clamav-db clamd clamav-devel amavisd-new
编辑/etc/amavisd.conf,修改下面的内容 这个源超级慢啊。以前很快的 ,不知道为何现在很慢呢$mydomain = 'yiyou.org'; # a convenient default for other settings
把下面内容去掉注释,并修改为下面
['ClamAV-clamd',
\&ask_daemon, ["CONTSCAN {}\n", "/tmp/clamd.socket"],
qr/\bOK$/, qr/\bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
$final_virus_destiny = D_DISCARD;
$final_banned_destiny = D_BOUNCE;
$final_spam_destiny = D_PASS;/这里原来是bounce直接拒绝,我说我从163发信直接收不到,,分提高到7.多都不行改成pass
$final_bad_header_destiny = D_PASS;
[root@localhost ~]# usermod -G amavis clamav
[root@localhost ~]# service clamd start
在/etc/postfix/master.cf 增加下面的内容: smtp-amavis unix - - n - 4 smtp 这里不知道是什么意思。。改天问问键盘
-o smtp_data_done_timeout=1200
-o smtp_send_xforward_command=yes

-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o receive_override_options=no_header_body_checks
在/etc/postfix/main.cf 加入下面的内容 content_filter = smtp-amavis:[localhost]:10024
[root@localhost ~]# service postfix reload
11、安装extman/extmail
A、配置apache
修改/etc/httpd/conf/httpd.conf,将下面的选项改为: User vuser
Group vgroup
[root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim extmail.conf
输入下面的内容: Alias /extman/cgi/ /var/www/extsuite/extman/cgi/
Alias /extman /var/www/extsuite/extman/html/
SetHandler cgi-script
Options +ExecCGI
# config for ExtMail
Alias /extmail/cgi/ /var/www/extsuite/extmail/cgi/
Alias /extmail /var/www/extsuite/extmail/html/
SetHandler cgi-script
Options +ExecCGI
[root@localhost ~]# mkdir /var/www/extsuite
[root@localhost ~]# tar zxf extmail-1.0.5b1.tar.gz
[root@localhost ~]# cp -r extmail-1.0.5b1 /var/www/extsuite/extmail
[root@localhost ~]# cp -r extman-0.2.5b1 /var/www/extsuite/extman
B、配置extmail参数 [root@localhost ~]# cd /var/www/extsuite/extmail/
[root@localhost extmail]# cp webmail.cf.default webmail.cf
修改webmail.cf 下面的选项 SYS_SESS_DIR = /tmp/extmail
SYS_MAILDIR_BASE = /home/data/domains
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
C、配置extman参数 [root@localhost extmail]# cd /var/www/extsuite/extman/
修改webman.cf 下面的选项: SYS_MAILDIR_BASE = /home/data/domains
D、创建session 目录 [root@localhost extman]# mkdir /tmp/{extman,extmail}
[root@localhost extman]# chown vuser:vgroup /tmp/ext*
E、配置后台日志分析工具 [root@localhost addon]# cd /var/www/extsuite/extman/addon/
[root@localhost addon]# cp -r mailgraph_ext /usr/local/
将下面的内容加入/etc/rc.local /usr/local/mailgraph_ext/mailgraph-init start
/usr/local/mailgraph_ext/qmonitor-init start
安装所依懒的软件包 [root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail
F、启动后台进程 [root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/qmonitor-init start
Starting queue statistics grapher: qmonitor
[root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start
Starting mail statistics grapher: mailgraph_ext
G、访问extmail/extman
打开浏览器,输入 注意:your_ip_address 为你实际的ip
第一个测试用户为:postmaster 密码:extmail 域:extmail
打开浏览器,输入
extman root 用户为:root@extmail.org 密码为:extmail*123*
注意:进入系统后要修改密码及找回密码的提示问题、答案。
12、安装slockd 这里我还没装准备试试dspam
slockd 是一个基于策略的垃圾邮件软件,很多用户反映使用后,反垃圾效果非常明显,但是有部分用户由于对该软件的使用,特性不了解,而产生了很多麻烦。
所在在此建议,如果你对该软件不了解,或者系统里的垃圾邮件少,可以暂时不安装。 [root@localhost ~]# tar zxf slockd-0.2beta1.tar.gz
[root@localhost ~]# cp -r slockd-0.2beta1 /usr/local/slockd
[root@localhost ~]# cd /usr/local/slockd
将下面的内容加入/etc/rc.local /usr/local/slockd/slockd-init start
[root@localhost slockd]# vim config/main.cf (编辑slockd/config/main.cf)修改下面的内容 setsid 1 (去掉注释,让程序成为后台进程)
修改/etc/postfix/main.cf 将原先的内容: smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,< div>
