声明:本人也是个linux新手,是按照网上的文档安装成功的,现在就结合网上文档加上自己的实践贴一下安装配置过程
1.安装httpd-manual httpd system-config-httpd php-mysql mysqllibdbi-dbd-mysql mysql-connector-odbc mysql-server mysql-devel php-cli php-ldapphp-pdo php php-common
2.开启apache、mysql
#servicehttpd start
#service mysqld start
3.测试php环境和mysql
测试php
vi /var/www/html/test.php
内容如下:
<?php
phpinfo();
?>
在浏览器里输入http://yourip/test.php成功运行将会出现PHP的logo图标和配置信息。
测试PHP与MySQL数据库的协同工作
编写一个PHP测试网页，添加简单的数据库操作命令，用于验证与MySQL服务器的连接情况
# vi /var/www/html/testdb.php
代码如下：
<?php
$link=mysql_connect('localhost','root','');
if(!$link) echo"Fail!!!";
else echo"Success!!";
mysql_close();
?>
使用浏览器访问http://yourip/testdb.php进行测试。如果可以正常连接数据库
会显示“Success!!”，否则显示“Fail!!”
4.创建数据库
解压Extman到/var/www/html/
#tar zxvf extman-1.1.tar.gz -C /var/www/html
#cd /var/www/html
#mv extman-1.1 extman
#chown -R vmail:vmail extman/cgi
#mkdir /tmp/extman
#chown -R vmail:vmail /tmp/extman
导入mysql数据库结构及初始化数据，root密码默认为空提示输入密码直接回车即可
#mysql -u root -p < /var/www/html/extman/docs/extmail.sql
#mysql -u root -p </var/www/html/extman/docs/init.sql
5.设置DNS 要有MX记录
如果没有可用的DNS服务器就要自己安装并配置新的DNS服务器,这里就不再介绍了
6.源码编译安装postfix+dovecot邮件系统
1).创建安装postfix、dovecot以及运行webmail的用户
#groupadd -g 1200 postdrop
#groupadd -g 1000 postfix
#useradd -M -u 1000 -s /sbin/nologinpostfix -g postfix -G postdrop
#groupadd dovenull
#useradd -M dovenull -s /sbin/nologin -g dovenull
#groupadd dovecot
#useradd -M dovecot -s /sbin/nologin -g dovecot
#groupadd -g 1010 vmail
#useradd vmail -u 1010 -g vmail -d/mailbox -s /sbin/nologin
2)安装postfix
因为系统中已存在Sendmail这个MTA程序,我们需要用Postfix替换它，只要切换到Postfix就可以了，先不要卸载sendmail安装完postfix 切换系统默认的MTA之后再卸载sendmail
关闭sendmail服务
#service sendmail stop
#chkconfig --level 2345 sendmail off
安装postfix并选择Dovecot作为sasl发信认证模块
#tar zxvf postfix-2.8-20101217.tar.gz -C/usr/local/src/
# cd /usr/local/src/postfix-2.8-20101217/
生成Makefile文件，编译Postfix支持SMTP AUTH和TLS,CentOS5.5已包含了Openssl,头文件(例如ssl.h)在/usr/include/openssl中,如果自我编译Openssl请注意文件路径。
#make CCARGS='-DHAS_MYSQL -I/usr/include/mysql \
-DUSE_SASL_AUTH -DDEF_SERVER_SASL_TYPE=\"dovecot\" \
-DUSE_TLS -I/usr/include/openssl' \
AUXLIBS='-L/usr/lib/mysql -lmysqlclient -lz-lm \
-L/usr/lib -lssl -lcrypto'
#make install
编译完后会进入交互式的问答，选择默认值即可，可参照如下设置：
install_root: [/]
config_directory: [/etc/postfix]
tempdir: [/tmp]
command_directory: [/usr/sbin]
daemon_directory: [/usr/libexec/postfix]
data_directory: [/var/lib/postfix]
html_directory: [no]
mail_owner: [postfix]
mailq_path: [/usr/bin/mailq]
manpage_directory: [/usr/local/man]
newaliases_path: [/usr/bin/newaliases]
queue_directory: [/var/spool/postfix]
readme_directory: [no]
sendmail_path: [/usr/sbin/sendmail]
setgid_group: [postdrop]
安装完毕。
检查postfix支持的SASL验证类型,参数-a查询服务器端类型，用来验证登录用户，-A查询客户端类型，Postfix用来和别的服务器通讯。
#postconf -a
显示：dovecot
说明现在已经支持dovecot认证了
查看是否支持mysql
#postconf –m
显示内容如果有mysql说明支持mysql
创建邮箱目录,假定虚拟用户邮件全部在/mailbox中。
#mkdir /mailbox
#chown -R vmail:vmail /mailbox/
附相关配置文件,请根据实际情况修改。邮箱采用Maildir格式，用户的邮箱目录格式是/mailbox/domain/username/Maildir
先备份main.cf配置文件
#cp /etc/postfix/main.cf/etc/postfix/main.cf.bak
然后编辑
#vi /etc/postfix/main.cf
清空内容添加以下内容：

注意smtpd_recipient_restrictions 后面的内容要放在一行如果想放在多行，每行结尾需要“，”隔开并且每行首要有空格
启动postfix
#postfix start
停止postfix
#postfix stop
重新加载postfix
#postfix reload
3).安装Dovecot
下载地址http://www.dovecot.org/
安装dovecot
#tar zxvf dovecot-2.0.8.tar.gz-C /usr/local/src/
#cd /usr/local/src/dovecot-2.0.8/
配置参数使Dovecot支持Mysql数据库生成Makefile文件。
#CPPFLAGS='-I/usr/include-I/usr/include/openssl' \
LDFLAGS='-L/usr/lib' ./configure --prefix=/usr/local/dovecot \
--sysconfdir=/etc--localstatedir=/var --with-sql --with-mysql --with-ssl=openssl
#make
#make install
默认配置文件在/etc/dovecot目录:
#cd/usr/local/dovecot/share/doc/dovecot/example-config/
#cp dovecot.confdovecot-sql.conf.ext /etc/dovecot/
#cd /etc/dovecot/
#mvdovecot-sql.conf.ext dovecot-mysql.conf
#vi/etc/dovecot/dovecot.conf
清空并添加内容如下：
protocols = imap pop3
listen = *
base_dir =/usr/local/dovecot/
auth_debug = yes
auth_default_realm =test.com
default_login_user =dovecot
default_internal_user =dovecot
disable_plaintext_auth =no
ssl = no
mail_uid = 1010
mail_gid = 1010
first_valid_uid = 1010
last_valid_uid = 1010
log_path =/var/log/dovecot.log
mail_location =maildir:/mailbox/%d/%n/Maildir
pop3_uidl_format=%08Xu%08Xv
auth default {
mechanisms = plain login
passdb sql {
args = /etc/dovecot/dovecot-mysql.conf
}
userdb sql {
args = /etc/dovecot/dovecot-mysql.conf
}
socket listen {
client {
path =/var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}
注意：
邮箱格式，在dovecot中%d代表域名(domain)，
%n代表用户名称(user)，%u代表user@domain。
编辑dovecot-mysql.conf
#vi /etc/dovecot/dovecot-mysql.conf
清空并添加内容如下：
driver = mysql
connect = host=localhostdbname=extmail user=extmail password=extmail
default_pass_scheme =MD5-CRYPT
password_query = SELECTpassword, maildir as userdb_home FROM mailbox WHERE username = '%u'
user_query = select 1010as uid ,1010 as gid from mailbox where username='%u' And active='1'
注意：default_pass_scheme为密码加密方式如果设置错误会导致outlook等邮件客户端不能收信
启动dovecot服务
#/usr/local/dovecot/sbin/dovecot-c /etc/dovecot/dovecot.conf
