邮件系统简介
邮件系统组成部分: MTA MSA ,MUA,MDA,MAA
1 MUA ：是Mial User Agent 的简称 ，是邮件系统的客户端程序，它提供了阅读，发送和接受电子邮件的用户接口，如：linux中的Mail ，Windowns中的Foxmail，Outlook 等
2 MSA ：是Mail Submmission Agent的简称。是邮件提交代理，负责消息有MTA发送之前必须完成所有准备工作和错误检测，MSA是在MUA和MTA之间插入了一个头脑清醒的检测员，对所有的主机名，从MUA 得到的头信息等信息进行检测
3 MTA：是Mail Transfer Agent 的简称，邮件转发代理，负责邮件的存储和转发；监视用户的代理请求，根据电子邮件的目标地址找出对应的电子邮件服务器，并将信件在服务器之间传输并且将接受到的邮件进行缓冲。Linux 下有sendmail .Postfix,qmail 等
4 MDA ：是Mail Ddlivery Agent 的简称。邮件投递代理，从MTA接受邮件并进行适当的本地投递，可以投递一个本地用户，一个邮件列表，一个文件或者是一个程序
5 MAA ：是Mail Access Agent。邮件访问代理，用于将用户连接到系统邮件库，使用POP或者Imap协议收取邮件。Linux 下常用的MAA有，Cyrus-IMAP,COURIER-IMAP等邮件中继，当邮件的目的传输是一旦源地址和目的地址都不是本地系统，那么本地系统就是邮件中继站(即是中转站)
注意：在安装postfix或多或少遇到一些error，我在文档
记录了一部分
或许记录的不完全，再遇到error时，可以多查找一些资料文件
第一：安装cmake工具
安装步骤一点点的来，先从LAMP平台来安装，先安装mysql，我这是一台新安装的linux系统，所以遇到的问题可能会比较多一点
因为mysql自5.5版本以后都是需要借助工具cmake，所以先从安装cmake工具开始
解压cmake的包，之后编译安装即可
[root@server250 cmake-2.8.4]# ./configure && make && make install
中间过程
[ 56%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_enum.o
[ 56%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_int.o

[ 57%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_regex.o
Linking C static library libcmForm.a
第二安装mysql
Ok，之后开始安装mysql，先建立mysql的用户名，组名
[root@server250 ~]# groupadd mysql
[root@server250 ~]# useradd -g mysql -s /sbin/nologin -M mysql
[root@server250 postfix]# tar zxvf mysql-5.5.19.tar.gz
[root@server250 mysql-5.5.19]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/data/mysql -DMYSQL_TCP_PORT=3306
make && make install
cp support-files/my-medium.cnf /etc/my.cnf
[root@server250 mysql]# chown -R mysql:mysql /usr/local/mysql/
[root@server250 mysql]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/
Installing MySQL system tables...
OK
Filling help tables...
OK
[root@server250 ~]# echo "/usr/local/mysql/lib/" >> /etc/ld.so.conf
[root@server250 ~]# ldconfig -v
[root@server250 ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
cp：是否覆盖“/etc/init.d/mysqld”? y
[root@server250 ~]# chmod 755 /etc/init.d/mysqld
[root@server250 ~]#
[root@server250 ~]#
[root@server250 ~]# service mysqld start
[root@server250 ~]# netstat -anpt | grep 3306
tcp 0 0 :::3306 :::* LISTEN 27783/mysqld
设置mysql的密码
[root@server250 ~]# mysqladmin -u root password "biao_123"
第三安装cyrus-sasl
[root@server250 postfix]# tar zxvf cyrus-sasl-2.1.22.tar.gz
[root@server250 cyrus-sasl-2.1.22]# ./configure --prefix=/usr/local/sasl2 --disable-gssapi --disable-anon --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 --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket
config.status: creating Makefile
config.status: creating saslauthd.h
config.status: executing depfiles commands
Configuration Complete. Type 'make' to build.
到这里就可以了
Make && make install
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I../lib -I../sasldb -I../include -I/usr/local/mysql//include/mysql -Wall -W -g -O2 -MT sql.lo -MD -MP -MF .deps/sql.Tpo -c sql.c -fPIC -DPIC -o sql.lo
sql.c:65:19: error: mysql.h: No such file or directory
解决办法：
在你的路径：I/usr/local/mysql//include/mysql 下面看看有没有 .h的文件，没有的话，在mysql是上一层目录中，有这些文件，拷贝一份到mysql下
[root@server250 include]# cp *.sh mysql
Make && make install
这个安装好后，要关掉系统自带的sasl2
mv /usr/lib/libsasl2.a /usr/lib/libsasl2.a.bak
mv /usr/lib/libsasl2.so.2.0.22 /usr/lib/libsasl2.so.2.0.22.OFF、
mv /usr/lib/sasl2 /usr/lib/sasl2.OFF
重新创建新编译的sasl库文件
[root@server250 ~]# ln -sv /usr/local/sasl2/lib/* /usr/lib/
创建指向“/usr/local/sasl2/lib/libsasl2.la”的符号链接“/usr/lib/libsasl2.la”

创建指向“/usr/local/sasl2/include/sasl/sasl.h”的符号链接“/usr/local/include/sasl.h”
创建指向“/usr/local/sasl2/include/sasl/saslplug.h”的符号链接“/usr/local/include/saslplug.h”
创建指向“/usr/local/sasl2/include/sasl/saslutil.h”的符号链接“/usr/local/include/saslutil.h”
启动
/usr/local/sasl2/sbin/saslauthd -a shadow pam
添加到库文件
[root@server250 local]# echo "/usr/local/sasl2/lib" >>/etc/ld.so.conf
[root@server250 local]# echo "/usr/local/sasl2/lib/sasl2/" >> /etc/ld.so.conf
[root@server250 local]#
[root@server250 local]#
[root@server250 local]#
[root@server250 local]# ldconfig -v
Ok
第四编译安装apache
完成以上后，开始安装apache
[root@server250 postfix]# tar jxvf httpd-2.2.21.tar.bz2
[root@server250 postfix]# ./configure --prefix=/usr/local/apache --enable-so --enable-track-vars --enable-rewrite --with-zlib --enable-mods-shared=most --enable-suexec --with-suexec-caller=daemon
Make makeinstall
第五编译安装php
[root@server250 postfix]# tar zxvf php-5.3.6.tar.gz
[root@server250 php-5.3.6]# ./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-libxml-dir --with-png-dir --with-jpeg-dir --with-zlib --with-freetype-dir --with-gd-dir --enable-mbstring=all
[root@server250 ~]# ln -sv /usr/local/mysql/include/* /usr/local/mysql/include/mysql

[root@server250 ~]# ln -sv /usr/local/mysql/include/* /usr/local/mysql/include/mysql
[root@server250 php-5.3.6]# ./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-libxml-dir --with-png-dir --with-jpeg-dir --with-zlib --with-freetype-dir --with-gd-dir --enable-mbstring=all
Make && make install
第六，php+apache+mysql的整合
Ok，安装php之后，则是可以进行修改http的文件，即是php+apache的整合
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
[root@localhost htdocs]# vi test.php
<?php
phpinfo();
?>
在directory 目录处添加index。Php和index.html在一起
之后测试
如下所示是正确的
第七：安装postfix
Ok，之上都已经完全安装了，下面就开始安装postfix
增加用户名
[root@server250 ~]# groupadd -g 503 postfix
[root@server250 ~]# useradd -g postfix -u 503 postfix
[root@server250 ~]#
[root@server250 ~]# groupadd -g 504 postdrop
[root@server250 ~]# useradd -g postdrop -u 504 -s /sbin/nologin -M postdrop
[root@server250 postfix]# tar zxvf postfix-2.8.7.tar.gz
root@localhost postfix-2.8.7]# make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -DUSE_TLS -I/usr/local/ssl/include/openssl ' 'AUXLIBS=-L/usr/local/mysql/lib -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/ssl/lib -lssl -lcrypto'
daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec
data_directory: [/var/lib/postfix] /usr/local/postfix/lib
html_directory: [no] /var/www/postfix_html
manpage_directory: [/usr/local/man] /usr/local/postfix/man
修改配置文件
/etc/postfix/main.cf
[root@server250 ~]# /usr/sbin/postfix start
postfix/postfix-script: starting the Postfix mail system
[root@server250 postfix-2.8.7]# netstat -anpt | grep 25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 3455/master
修改防火墙的配置文件，添加25端口
[root@server250 ~]# vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
重启防火墙
接下来是验证postfix是否安装成功
[root@server250 ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 mail.ku888.in ESMTP Postfix

.
250 2.0.0 Ok: queued as 048B45CF00A3
quit
221 2.0.0 Bye
Connection closed by foreign host.
第八，配置postfix的虚拟用户邮箱
验证ok后，下面开始部署安装postfix的虚拟用户和邮箱设置
先确认下你的postfix是否支持 cyrus-sasl的认证
[root@mail2 ~]# postconf -a
cyrus
Dovecot
Ok，支持的
下面进行设置
[root@mail2 ~]# vi /etc/postfix/main.cf
编辑她的配置文件
在末尾处添加
############################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!
############################END-CYRUS-SASL############################
在sasl2的库文件中，添加认证
[root@mail2 sasl2]# vi smtpd.conf
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
~
重新加载postfix的配置文件，
重新telnet ，验证下是否有加载上SASL认证
[root@mail2 ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to mail2.51coolbar.com (127.0.0.1).
Escape character is '^]'.
220 Welcome to our mail2.51coolbar.com ESMTP,Warning: Version not Available!
ehlo localhost
250-mail2.51coolbar.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN 确保这两行的输出，否则都是有问题的
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
Ok，发现是加载上了
配置虚拟用户和虚拟域
编辑postfix的主配置文件
########################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_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
##############END--############################################
添加支持虚拟域和虚拟用户所需要的配置文件
[root@mail2 postfix]# vi mysql_virtual_domains_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain
~
[root@mail2 postfix]# vi mysql_virtual_mailbox_limit_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username
[root@mail2 postfix]# vi mysql_virtual_mailbox_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username
[root@mail2 postfix]# vi mysql_virtual_alias_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address
~
四个配置文件
第九，安装courier-authlib
Ok了，下面开始安装
courier-authlib
[root@mail2 courier-authlib-0.63.0]# ./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --without-authpam -without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql -with-mysql-includes=/usr/local/mysql/inculde/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc CFLAGS="-march=x86-64 -O2 -fexpensive-optimizations" CXXFLAGS="-march=x86-64 -O2 -fexpensive-optimizations"
其中有一个error，
提示找不到expect not found - will not be able to change passwds 导致configure: error: --with-authmysql specified but no mysqlclient.so
解决办法：
[root@mail2 lib]# cp /usr/local/mysql/lib/libmysqlclient.so /usr/lib/libmysqlclient.so
之后重新编译即可过去
./configure 过后，执行make提示authmysql.h:8:19: 错误：mysql.h：没有那个文件或目录
authmysql.h:9:20: 错误：errmsg.h：没有那个文件或目录
make[2]: *** [authmysql.lo] 错误 1
Vi authmysql.h的文件
Mysql/mysql.h
保存即可
[root@mail2 var]# chmod -R 755 /usr/local/courier-authlib/var/spool/authdaemon/
进入到目录/etc/
[root@mail2 etc]# cp authdaemonrc.dist authdaemonrc
[root@mail2 etc]# cp authmysqlrc.dist authmysqlrc
编辑文件authdaemonrc
authmodulelistorig="authmysql"
daemons=10
authmodulelist="authmysql"
编辑文件authmysql
MYSQL_SERVER 127.0.0.1
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /data/mysql/mysql.sock 数据库的监听文件
MYSQL_PORT 3306 数据库的端口
MYSQL_DATABASE extmail 数据库
MYSQL_USER_TABLE mailbox 数据库的表
MYSQL_CRYPT_PWFIELD password 加密的字段
MYSQL_UID_FIELD 503 邮件服务的属主和属组
MYSQL_GID_FIELD 503
MYSQL_HOME_FIELD concat('/var/mailbox/',maildir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)
ourier-authlib 的库文件搜索路径，并启动courier-authlib
[root@mail2 postfix]# /usr/local/courier-authlib/sbin/authdaemond start
[root@mail2 postfix]# echo "/usr/local/courier-authlib/lib/courier-authlib/lib" >> /etc/ld.so.conf
[root@mail2 postfix]# ldconfig -v
第十安装IMAP服务，
安装imap服务
[root@mail2 postfix]# tar jxvf courier-imap-4.8.0.tar.bz2
[root@mail2 ~]# ./configure --prefix=/usr/local/courier-imap --with-redhat --enable-unicode --disable-root-check --with-openssl --with-trashquota --without-ipv6 CPPFLAGS='-I/usr/local/courier-authlib/include' LDFLAGS='-L/usr/local/courier-authlib/lib/courier-authlib' COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig'
Make && make install
进入到/usr/local/courier-imap/etc下面，去复制imap启动需要的配置文件
[root@mail2 etc]# cp imapd-ssl.dist imapd-ssl
[root@mail2 etc]# cp imapd.dist imapd
[root@mail2 etc]# cp pop3d.dist pop3d
[root@mail2 etc]# cp pop3d-ssl.dist pop3d-ssl
配置courier-imap ,为用户提供服务的类型，该处为用户提供的是pop3d 服务，如果为用户提供IMAP 服务，只需要修改对应的选项
IMAPDSTART=YES
[root@mail2 etc]# vi pop3d
POP3DSTART=YES
将NO改为YES
为虚拟用户创建邮箱所在目录,并修改权限.把其所属主改为postfix
[root@localhost mail]# mkdir -pv /var/mailbox/
[root@localhost mail]# chown -R postfix:postfix /var/mailbox/
配置SMTP 认证，同样需要修改在前面创建的/usr/local/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path: /usr/local/courier-authlib/var/spool/authdaemon/socket
手动启动imap的服务
[root@localhost mail]# /usr/local/courier-imap/libexec/pop3d.rc start
[root@localhost mail]# /usr/local/courier-imap/libexec/imapd.rc start
查看是否启动ok，两个端口，110和143
[root@localhost mail]# netstat -anpt | grep 110
tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 3822/couriertcpd
tcp 0 20 192.168.225.180:110 89.137.252.99:21639 ESTABLISHED 30768/pop3login
[root@localhost mail]# netstat -anpt | grep 143
tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 3816/couriertcpd
[root@localhost mail]# vi /etc/sysconfig/iptables
开放110和143端口
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 143 -j ACCEPT
[root@mail2 ~]# service iptables restart
清除防火墙规则：[确定]
把 chains 设置为 ACCEPT 策略：filter [确定]
正在卸载 Iiptables 模块：[确定]
应用 iptables 防火墙规则：[确定]
载入额外 iptables 模块：ip_conntrack_netbios_ns [确定]
第十一安装extmail
Ok，安装完imap后，开始安装网页上的extmail软件
[root@mail2 postfix]# tar zxvf 51CTO下载-extmail-1.2.tar.gz
因为extmail相当于web 版的outlook，因此将其放到了apache下面的
Mv extmail-1.2 /usr/local/apache/htdocs/extmail
进入到/usr/local/apache/htdocs/extmail下面
复制一份主配置文件
[root@mail2 extmail]# cp webmail.cf.default webmail.cf
之后修改主配置文件（根据你的实际路径进行更改）
SYS_CONFIG = /usr/local/apache/htdocs/extmail/
SYS_LANGDIR = /usr/local/apache/htdocs/extmail/lang
SYS_TEMPLDIR = /usr/local/apache/htdocs/extmail/html
SYS_USER_LANG = zh_CN
SYS_MYSQL_USER = extmail 连接mysql数据库使用的数据库名
SYS_MYSQL_PASS = extmail 数据库密码
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /data/mysql/mysql.Sock 数据库的sock文件
# table name
SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password
SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket
更改完成后，修改apache的配置文件，将其与extmail想结合
Vi /usr/local/apache/conf/httpd.Conf
User postfix
Group postfix
<Directory "usr/local/apache/htdocs/extmail/cgi">
Options Indexes FollowSymLinks +ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
安装Unix-Syslog ，因为extmail 会用到DBD：syslog
下载 Unix-Syslog-1.1.tar.gz
下载DBD-mysql-4.020.tar.gz
#tar xvf Unix-Syslog-1.1.tar.gz.gz
#cd Unix-Syslog-1.1
#perl Makefile.PL
# make
#make install
cd DBD-mysql-4.020
#perl Makefile.PL
#make
#make install
Ok.之后测试extmail是否可以访问ok
第十二：安装extman
安装extman和安装extmail的方法是一样的，
解压，mv
Mv extman-1.1 /usr/local/apache/htdocs/extman
复制文件
cp webman.cf.default webman.Cf
编辑文件
extman]# vi webman.Cf
SYS_CONFIG = /usr/local/apache/htdocs/extman/
SYS_LANGDIR = /usr/local/apache/htdocs/extman/lang
SYS_TEMPLDIR = /usr/local/apache/htdocs/extman/html
SYS_MAILDIR_BASE = /var/mailbox/
SYS_SESS_DIR = /var/tmp/extman/
SYS_BACKEND_TYPE = mysql
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = 127.0.0.1
SYS_MYSQL_SOCKET = /data/mysql/mysql.Sock
保存退出，修改apache文件
<Directory "/usr/local/apache/htdocs/extman/cgi">
Options Indexes FollowSymLinks +ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
需重启apache，才能生效
创建数据库，把docs 目录下面的导入到数据库中，但是在导入数据库前需要把extmail.sql 文件中的TYPE=MyISAM 改成ENGINE=MyISA
#mysql –uroot –p <extmail.sql
#mysql –uroot –p <init.sql
修改cgi 目录的属主
#chown –R postfix.Postfix /usr/local/apache/htdocs/extman/cgi/
为extman 授权数据库访问权限
#mysql -uroot –p
mysql> grant all privileges on extmail.* TO extmail@localhost IDENTIFIED BY 'extmail';
mysql> grant all privileges on extmail.* TO extmail@127.0.0.1 IDENTIFIED BY 'extmail';
之后再测试extman是否可以登录，配置文件提到的几个文件都要建立
/var/mailbox/
/var/tmp/extman/
这两个目录要需要提前建立好
第十三：搭建图形日志
之后开始安装postfix图形日志
下载包Time-HiRes-1.9721.tar.gz
下载File-Tail-0.99.3.tar.gz
下载cgilib-0.5.tar.gz
tar zxvf Time-HiRes-1.9721.tar.gz
Time-HiRes-1.9721]# perl Makefile.PL
Time-HiRes-1.9721]# make
Time-HiRes-1.9721]# make test
[root@mail Time-HiRes-1.9721]# make test
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/HiRes....ok
All tests successful.
Time-HiRes-1.9721]# make install
postfix]# tar zxvf File-Tail-0.99.3.tar.gz
[root@mail postfix]# cd File-Tail-0.99.3
[root@mail File-Tail-0.99.3]# perl Makefile.PL
[root@mail File-Tail-0.99.3]# make && make install
[root@mail postfix]# tar zxvf rrdtool-1.4.4.tar.gz
#./configure --prefix=/usr/local/rrdtool
#make
#make install
从目录/usr/local/apache/htdocs/extman/addon下，拷贝目录
Cp -r /usr/local/apache/htdocs/extman/addon/mailgraph_ext /usr/local
启动
[root@mail ~]# /usr/local/mailgraph_ext/mailgraph-init start
之后通过extman管理平台查看是否都ok的
