CentOS6 安装Sendmail + Dovecot + Roundcubemail

前言 

  本文是继CentOS6 安装Sendmail + Dovecot + Squirrelmail 关于邮箱服务器配置的第二篇文章,因为关于使用Sendmail进行相关配置的文章、资料等太老,而且资料也不全,而使用Postfix的比较容易找到完备的资料,此处不讨论Sendmail和Postfix的优劣,仅仅是记录配置过程,希望对你有帮助。

  此外,这里只是演示一个搭建本地邮箱环境,如果要投入真正使用,还需要搭建一个DNS,还得要有一个域名。这里会演示搭建本地环境的完整的一个过程,就不包括安装虚拟机了,这篇文章跟前一篇在安装Sendmail和Dovecot基本上是重复的,仅演示必要过程,不做过多解释。

准备阶段

1、基本命令使用

[lz@mail ~]$ sudo -i          【获取系统root权限】
[root@mail ~]# cat /etc/issue     【查看系统发行版本】
CentOS release 6.9 (Final)
Kernel \r on an \m
[root@mail ~]# cat /etc/sysconfig/network      
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=mail.roundcubemail.com    【修改下主机名,重启生效,不过不急于重启】
[root@mail ~]# hostname
mail.roundcubemail.com         【改成你的主机名】
[root@mail lz]# cat /etc/hosts
127.0.0.1 mail.roundcubemail.com localhost          【将主机名和域名添加到hosts文件中】
127.0.0.1 roundcubemail.com localhost
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
[root@mail lz]# ping -c 1 mail.roundcubemail.com           【这样就会自动解析成本地地址,这样就能使用这个名字啦】
PING mail.roundcubemail.com (127.0.0.1) 56(84) bytes of data.
64 bytes from mail.roundcubemail.com (127.0.0.1): icmp_seq=1 ttl=64 time=0.073 ms
[root@mail lz]# ping -c 1 roundcubemail.com
PING roundcubemail.com (127.0.0.1) 56(84) bytes of data.
64 bytes from mail.roundcubemail.com (127.0.0.1): icmp_seq=1 ttl=64 time=0.015 ms

2、系统更新

[root@mail lz]# yum update
Loaded plugins: fastestmirror, refresh-packagekit
Setting up Update Process
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.nju.edu.cn
* updates: mirrors.aliyun.com
No Packages marked for Update

关于系统更新就不演示过程,会比较耗时,只需一条命令即可更新。

3、关于root权限获取

如果你在使用sudo -i获取root权限失败,显示没有sudo权限,可以通过如下方式获取root权限

[lz@mail ~]$ su root
Password:                     【输入lz的用户密码】
[root@mail lz]# vim /etc/sudoers

CentOS6 安装Sendmail + Dovecot + Roundcubemail

将你的用户名添加到root后面,此处为lz, 保存文件之后就能正常使用sudo -i命令了。

安装LAMP环境

1、安装apache2

[root@mail lz]# yum install httpd
Loaded plugins: fastestmirror, refresh-packagekit
Setting up Install Process
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.nju.edu.cn
* updates: mirrors.aliyun.com
Package httpd-2.2.15-60.el6.centos.4.x86_64 already installed and latest version
Nothing to do
[root@mail lz]# service httpd status        【apache2默认应该是安装好了的,但并没有启动】
httpd is stopped
[root@mail lz]# service httpd start         【启动】
Starting httpd: [ OK ]
[root@mail lz]# chkconfig httpd on         【设置为开机自动启动】

这个时候访问虚拟机ip地址,应该就可以看到如下页面

CentOS6 安装Sendmail + Dovecot + Roundcubemail

2、安装PHP

因为Roundcubemail要求php > 5.3.7, 我们需要使用一个更新的源。原文参考:Centos 6.x/7.x yum安装php5.6.X(最新版)

a) 检查当前安装的php包

[root@mail lz]# yum list installed | grep php

如果之前安装过旧版本的php可以使用如下命令删除

yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64 

b) 配置yum源

追加CentOS 6.5的epel及remi源:

rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

CentOS 7.0的源:

yum install epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

查看可安装的包:

yum list --enablerepo=remi --enablerepo=remi-php56 | grep php

c) 安装php5.6

yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof

d) 查看php版本

[root@mail lz]# php --version
PHP 5.6.31 (cli) (built: Jul 6 2017 08:16:47)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
with Xdebug v2.5.5, Copyright (c) 2002-2017, by Derick Rethans

e) 测试

[root@mail lz]# cd /var/www/html/
[root@mail html]# ls
[root@mail html]# vim info.php
[root@mail html]# cat info.php
<?php
phpinfo();
?>

好像需要重启一下apache

[root@mail html]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]

CentOS6 安装Sendmail + Dovecot + Roundcubemail

3、安装Mysql

一坨安装,参考CentOS6.4+LAMP+Postfix+Dovecot+Postfixadmin+Roundcubemail 打造企业级邮件服务器 (1)  中第五步:五、安装并配置LAMP环境

会显示有一些错误,不过没有关系...

[root@mail html]# yum -y install httpd mysql mysql-devel mysql-server php php-pecl-Fileinfo php-mcrypt php-devel php-mysql php-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc pcre pcre-devel

创建数据库:roundcubemail

[root@mail html]# service mysqld start          【启动mysql】
[root@mail html]# chkconfig mysqld on           【设置mysql开机启动】
[root@mail html]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2

Query OK, 0 rows affected (0.00 sec) mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec) mysql> quit
Bye

到这里LAMP安装完成。

Sendmail 安装和配置

1、安装mail相关工具包

[root@mail html]# yum install m4 telnet mailx

2、Sendmail安装

[root@mail html]# yum install sendmail sendmail-cf

3、Sendmail配置

a) 下面将使用m4这个工具来创建sendmail.cf这个文件

[root@mail html]# netstat -an | grep :25 | grep tcp
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN
[root@mail html]# cd /etc/mail
[root@mail mail]# pwd
/etc/mail
[root@mail mail]# ls
access aliasesdb-stamp domaintable.db local-host-names mailertable.db Makefile sendmail.cf.bak submit.cf trusted-users virtusertable.db
access.db domaintable helpfile mailertable make sendmail.cf sendmail.mc submit.mc virtusertable
[root@mail mail]# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

b) 配置相关域名

在local-host-names增加域名项,表示的是可以用来发送/接收邮件的域名。

[root@mail mail]# vim /etc/mail/local-host-names
[root@mail mail]# cat /etc/mail/local-host-names
# local-host-names - include all aliases for your machine here.
roundcubemail.com
mail.roundcubemail.com
[root@mail mail]# service sendmail restart  
Shutting down sm-client: [ OK ]
Shutting down sendmail: [ OK ]
Starting sendmail: [ OK ]
Starting sm-client: [ OK ]
[root@mail mail]# chkconfig sendmail on            [设置开机启动]

4、Sendmail 发信测试:mail命令测试

先新建两个用户

[root@mail mail]# useradd user1
[root@mail mail]# useradd user2
[root@mail mail]# passwd user1
Changing password for user user1.
New password:                   【输入密码】
BAD PASSWORD: it does not contain enough DIFFERENT characters
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
[root@mail mail]# passwd user2           【输入密码
Changing password for user user2.
New password:
BAD PASSWORD: it does not contain enough DIFFERENT characters
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
[root@mail mail]# gpasswd -a user1 mail     【加入mail用户组】
Adding user user1 to group mail
[root@mail mail]# gpasswd -a user2 mail
Adding user user2 to group mail

用其中一个账户登陆,给另一个用户发送邮件:

[root@mail mail]# su user1              【切换到user1】
[user1@mail mail]$ mail -s "hello user2" user2
This is test a mail from user1.
.                             【.表示结束】     
EOT
[user1@mail mail]$ cat /var/mail/user2
From user1@mail.roundcube.com Mon Aug 14 22:28:15 2017

5、Sendmail 发信测试: telnet方式测试

CentOS6 安装Sendmail + Dovecot + Roundcubemail

Sendmail安装测试成功。

Dovecot安装和配置

1、安装相关工具包

[root@mail mail]# yum install telnet mailx mutt

2、Dovecot安装

[root@mail mail]# yum install dovecot

3、Dovecot配置

[root@mail mail]# ls /etc/dovecot/
conf.d dovecot.conf
[root@mail mail]# vim /etc/dovecot/dovecot.conf

CentOS6 安装Sendmail + Dovecot + Roundcubemail

[root@mail mail]# ls /etc/dovecot/conf.d/
10-auth.conf 10-master.conf 20-lmtp.conf 90-quota.conf auth-master.conf.ext auth-system.conf.ext
10-director.conf 10-ssl.conf 20-pop3.conf auth-checkpassword.conf.ext auth-passwdfile.conf.ext auth-vpopmail.conf.ext
10-logging.conf 15-lda.conf 90-acl.conf auth-deny.conf.ext auth-sql.conf.ext
10-mail.conf 20-imap.conf 90-plugin.conf auth-ldap.conf.ext auth-static.conf.ext
[root@mail mail]# vim /etc/dovecot/conf.d/10-mail.conf

设置:mail_location = mbox:~/mail:INBOX=/var/mail/%u

CentOS6 安装Sendmail + Dovecot + Roundcubemail

[root@mail mail]# service dovecot start          【启动】
Starting Dovecot Imap: [ OK ]
[root@mail mail]# chkconfig dovecot on           【设置开机dovecot启动】

4、Dovecot 接收邮件测试: mutt命令

之前在测试Sendmail的时候,用user1这个账户向user2发送了一封邮件,通过查看本地文件进行验证。

[root@mail ~]# mutt -f imap://user2:123456@localhost              【用户user2  密码:123456】

Dovecot 安装测试成功。

Roundcubemail安装和配置

1、下载roundcubemail

roundcubemail 官网下载: https://roundcube.net/

下载完整版complete解压到web根目录:/var/www/html

[root@mail html]# pwd
/var/www/html
[root@mail html]# ls
info.php roundcubemail-1.3.0
[root@mail html]# mv roundcubemail-1.3.0/ roundcubemail      【改下名字】

2、配置installer

Step 1:

访问地址: http://192.168.1.103/roundcubemail/installer/      【修改成你的ip】

CentOS6 安装Sendmail + Dovecot + Roundcubemail

CentOS6 安装Sendmail + Dovecot + Roundcubemail

有个小问题: 时区没有设置,我们设置一下看看:

[root@mail html]# vim /etc/php.ini

CentOS6 安装Sendmail + Dovecot + Roundcubemail

apache服务器需要重启一下,再次访问正常:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

但是在重启apache的时候又会出现这样一个问题:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

可以根据提示,进行如下修改:

[root@mail html]# vim /etc/httpd/conf/httpd.conf

CentOS6 安装Sendmail + Dovecot + Roundcubemail

再次重启正常:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

Step2 :

点击下一步,我们进入创建配置文件Create config这一步,内容项有很多,下面仅贴出重要的相关项

基本配置:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

数据库配置:roundcubemail (这个跟之前创建的数据库相关,为了简便,全部设置为roundcubemail)

CentOS6 安装Sendmail + Dovecot + Roundcubemail

IMAP设置: 默认即可

CentOS6 安装Sendmail + Dovecot + Roundcubemail

SMTP设置: 默认即可

CentOS6 安装Sendmail + Dovecot + Roundcubemail

拉到页面底部,点击创建配置文件Create config

CentOS6 安装Sendmail + Dovecot + Roundcubemail

将创建好的配置文件config.inc.php放置在:/var/www/html/roundcubemail/config      【根据自己的实际情况进行相应的修改】

[root@mail html]# pwd
/var/www/html
[root@mail html]# ls
info.php roundcubemail
[root@mail html]# cd roundcubemail/config/
[root@mail config]# ls
config.inc.php.sample defaults.inc.php mimetypes.php
[root@mail config]# cp /home/lz/temp/config.inc.php ./
[root@mail config]# ls
config.inc.php config.inc.php.sample defaults.inc.php mimetypes.php
[root@mail config]# pwd
/var/www/html/roundcubemail/config

确定已经将配置文件放到config目录下之后,点击下一步:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

下面一步步进行展示:

[root@mail html]# pwd
/var/www/html
[root@mail html]# ls
info.php roundcubemail
[root@mail html]# cd roundcubemail/
[root@mail roundcubemail]# ls
bin composer.json-dist index.php installer logs program README.md SQL UPGRADING
CHANGELOG config INSTALL LICENSE plugins public_html skins temp vendor
[root@mail roundcubemail]# chmod a+w temp/       【赋予写权限】
[root@mail roundcubemail]# chmod a+w logs/

点击初始化按钮之后,页面会自动条状成如下,要求已经ok了:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

细心的同学可能会注意到在General configuration中temp_dir

temp_dir: /var/www/html/roundcubemail/temp/

和Logging & Debugging中log_dir

log_dir: /var/www/html/roundcubemail/logs/

测试一:

Sender: user1@mail.roundcubemail.com

Recipient: user2@mail.roundcubemail.com

主要是@后面的部分需要修改成你的配置...可以看到,这里测试ok了

CentOS6 安装Sendmail + Dovecot + Roundcubemail

测试二:

我们用user1:123456登陆测试, 验证成功。

CentOS6 安装Sendmail + Dovecot + Roundcubemail

3、Roundcubemail 登陆测试

Webmail 登陆:

用户名:密码: user1/user2: 123456

CentOS6 安装Sendmail + Dovecot + Roundcubemail

CentOS6 安装Sendmail + Dovecot + Roundcubemail

发信测试:

user2给user1发送邮件:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

切换成user1登陆查看邮件:

CentOS6 安装Sendmail + Dovecot + Roundcubemail

可以看到user1已经成功接收了user2发送的邮件。

至此,Sendmail + Dovecot + Roundcubemail 的环境搭建成功。
