2007-05-31 by kenthy#qingdaonews.com
##################
系统环境： RHEL4 [ 2.6.9-5.EL ] 主要软件版本： sendmail-8.13.1-2 dovecot-0.99.11-2.EL4.1 squirrelmail-1.4.3a-7.EL4 m4-1.4.1-16 bind-9.2.4-2 httpd-2.0.52-9.ent php-4.3.9-3.1 MailServer：@redhat.com 172.17.17.1/24 ################### 一、软件安装
为简化实验过程，直接使用RHEL4光盘上自带的rpm包安装各软件程序， 过程略
二、配置网络参数
1> # vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=172.17.17.1 NETMASK=255.255.255.0 BROADCAST=172.17.17.255 2> # vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=redhat.com 3> # vi /etc/hosts 127.0.0.1 localhost.localdomain localhost 172.17.17.1 redhat.com mail.redhat.com rhel.net mail.rhel.net mail
4> # vi /etc/resolv.conf nameserver 172.17.17.1 nameserver 202.106.0.20 nameserver 202.106.46.151 5> # service network restart 三、配置DNS服务器
1> # vi /var/named/chroot/etc/named.conf options { directory "/var/named"; forwarders { 202.106.0.20; 202.106.46.151; }; }; zone "redhat.com" IN { type master; file "redhat.com.zone"; }; zone "rhel.net" IN { type master; file "rhel.net.zone"; }; zone "17.17.172.in-addr.arpa" IN { type master; file "172.17.17.arpa"; }; 2> # vi /var/named/chroot/var/named/redhat.com.zone //rhel.net.zone类似
$TTL 86400 @ SOA redhat.com. root.redhat.com. ( 2007053001 3H 15M 1W 1200 ) IN NS mail.redhat.com. IN MX 10 mail.redhat.com. mail IN A 172.17.17.1 www IN CNAME mail 3> # vi /var/named/chroot/var/named/172.17.17.arpa $TTL 86400 @ SOA redhat.com. root.redhat.com. ( 2007053001 3H 15M 1W 1200 ) IN NS mail.redhat.com. IN MX 10 mail.redhat.com. 1 IN PTR mail.redhat.com. 4> # chkconfig --level 2345 named on # service named restart 四、配置sendmail服务器 [smtp]
1> # useradd -M -s /dev/null tom ; passwd tom # useradd -M -s /dev/null jerry ; passwd jerry # useradd -M -s /dev/null kitty ; passwd kitty 2> # vi /etc/mail/sendmail.mc //为测试方便，smtp认证可不作 DAEMON_OPTIONS(`Port=smtp,Addr=172.17.17.1, Name=MTA') dnl
dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf 3> # vi /etc/mail/local-host-names mail.redhat.com redhat.com localhost localhost.localdomain 3> # vi /etc/aliases admin: root,jerry # newaliases 4> # vi /etc/mail/access localhost.localdomain RELAY localhost RELAY 127.0.0.1 RELAY 172.17.17 RELAY redhat.com RELAY rhel.net RELAY # cd /etc/mail ; make access.db 5> # vi /etc/mail/sendmail.cw rhel.net # vi /etc/mail/virtusertable kitty@rhel.net jerry # cd /etc/mail ; make virtusertable.db 6> # chkconfig --level 2345 sendmail on # service sendmail restart 五、配置dovecot服务器 [pop3、imap]
1> # vi /etc/dovecot.conf protocols = pop3 pop3s imap imaps 2> # chkconfig --level 2345 dovecot on # service dovecot restart 六、配置webmail
1> # cp -rf /usr/share/squirrelmail/ /var/www/html/ # mv /var/www/html/squirrelmail /var/www/html/mail # cd /var/www/html/mail/config # rm -rf config.php config_local.php # ln -s /etc/squirrelmail/config.php ./ # ln -s /etc/squirrelmail/config_local.php ./ 2> # vi /etc/httpd/conf/httpd.conf DocumentRoot "/var/www/html/mail" <Directory "/var/www/html/mail"> Options Indexes AllowOverride None Order allow,deny Allow from all </Directory> 3> # chkconfig --level 2345 httpd on # service httpd restart 七、测试邮件服务器
1> 测试账户： tom@redhat.com jerry@redhat.com kitty@redhat.com tom@rhel.net jerry@rhel.net kitty@rhel.net 2> 测试方式： 使用Foxmail等MUA软件配置测试 通过浏览器访问http://mail.redhat.com或 |
