系统:

CentOS 7.1

IP:192.168.2.220

域名:mail.test.com

----------------------------------------------------------------------------------------

——安装前的准备工作

1)关闭Selinux

[root@node1 ~]# vi /etc/selinux/configSELINUX=disabled

2)安装程序依赖包

[root@node1 ~]# yum install db4-devel ntpdate cyrus-sasl-md5 perl-GD perl-DBD-MySQL perl-GD perl-CPAN perl-CGI perl-CGI-Session cyrus-sasl-lib cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel libtool-ltdl-devel telnet mail -y

3) 由于CentOS7默认安装的是MariaDB,所以要添加MySQL的yum源,有些编译需要的devel包只有epel有,所以我们把epel源也一并添加

yum install -y wgetwget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpmrpm -ivh mysql-community-release-el7-5.noarch.rpm wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -ivh epel-release-latest-7.noarch.rpm

4)安装Unix-Syslog补丁

[root@node1 soft]# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz[root@node1 soft]# tar fzvx Unix-Syslog-1.1.tar.gz[root@node1 soft]# cd Unix-Syslog-1.1[root@node1 Unix-Syslog-1.1]# perl Makefile.PL[root@node1 Unix-Syslog-1.1]# make && make install

注意:不安装此补丁的话使用extmail会报如下错误:

Unix::Syslog not found, please install it first! (in cleanup) Undefined subroutine &Ext::Logger::do_closelog called at /var/www/extsuite/extmail/libs/Ext/Logger.pm line 86.

----------------------------------------------------------------------------------------

6)为Extman创建临时目录并给予权限

[root@node1 docs]# mkdir /tmp/extman[root@node1 docs]# chown postfix.postfix -R /tmp/extman/

——重启postfix、dovecot、saslauthd、nginx

[root@node1 docs]# service postfix restart[root@node1 docs]# service dovecot restart[root@node1 docs]# service saslauthd restart

——测试虚拟用户实现结果

1)测试Postfix 支持虚拟用户

[root@node1 docs]# /usr/local/courier-authlib/sbin/authtest -s login postmaster@test.com extmail
Authentication succeeded.         
//  表示成功
      
Authenticated: postmaster@test.com   (uid

2)测试虚拟用户SMPT发信认证

[root@node1 docs]# printf   "postmaster@test.com" | openssl base64cG9zdG1hc3RlckBleHRtYWlsLm9yZw==[root@node1 docs]# printf   "extmail" | openssl base64ZXh0bWFpbA==[root@node1 docs]#[root@node1 docs]# telnet localhost 25Trying 127.0.0.1...Connected to localhost.localdomain (127.0.0.1).Escape character is '^]'.220 mail.benet.com ESMTP Postfixauth login334 VXNlcm5hbWU6cG9zdG1hc3RlckBleHRtYWlsLm9yZw==334 UGFzc3dvcmQ6ZXh0bWFpbA==235 2.0.0 Authentication successful       //  表示成功quit221 2.0.0 ByeConnection closed by foreign host.

——启动extmail和extman的相关程序

1)修改dispatch-initSU_UID和SU_GID

[root@node1 docs]# vi /var/www/extsuite/extmail/dispatch-initSU_UID=postfixSU_GID=postfix

2)启动dispatch-init并添加到/etc/rc.local [不启动dispatch-init]

[root@node1 docs]# /var/www/extsuite/extmail/dispatch-init start[root@node1 docs]# echo "/var/www/extsuite/extmail/dispatch-init start" >> /etc/rc.local

注意:不启动dispatch-init 连接extmail时候会报502错误。

3)启动cmdserver并添加到/etc/rc.local

[root@node1 docs]# /data/www/extman/daemon/cmdserver -v -d[root@node1 docs]# echo "/var/www/extsuite/extman/daemon/cmdserver -v -d " >> /etc/rc.local

注意:不启动cmdserver的话,extmail登录管理后台,系统信息里会报Connection refused错误

如果出现如下错误:Undefined subroutine &Ext::Utils::sort2name called at /var/www/extsuite/extmail/libs/Ext/App/Folders.pm line 387.

解决办法:

[root@node1 Ext]# cd /var/www/extsuite/extmail/libs/Ext[root@node1 Ext]# cp Utils.pm /var/www/extsuite/extman/libs/[root@node1 Ext]# cd /var/www/extsuite/extman/libs/Ext[root@node1 Ext]# mv Utils.pm ManUtils.pm[root@node1 Ext]# /var/www/extsuite/extmail/dispatch-init stop[root@node1 Ext]# /var/www/extsuite/extmail/dispatch-init start

——Extmail虚拟主机配置 [这里用的是nginx]

1)配置extmail虚拟主机

[root@node1 ~]# vi /usr/local/nginx/conf/conf.d/extmail.conf
server {
   
listen       
8080
;
   
server_name  mail.test.com;
   
index index.html index.htm index.php index.cgi;
   
root  /
var
/www/extsuite/extmail/html/;
   
location /extmail/cgi/ {
             
fastcgi_pass          
127.0
.
0.1
:
8888
;
             
fastcgi_index         index.cgi;
             
fastcgi_param  SCRIPT_FILENAME   /
var
/www/extsuite/extmail/cgi/$fastcgi_script_name;
             
include               
fcgi.conf;
        
}
        
location  /extmail/  {
             
alias  /
var
/www/extsuite/extmail/html/;
        
}
        
location /extman/cgi/ {
             
fastcgi_pass          
127.0
.
0.1
:
8888
;
             
fastcgi_index         index.cgi;
             
fastcgi_param  SCRIPT_FILENAME   /
var
/www/extsuite/extman/cgi/$fastcgi_script_name;
             
include            
fcgi.conf;
        
}
        
location /extman/ {
             
alias  /
var
/www/extsuite/extman/html/;
        
}
      
access_log  /usr/local/nginx/logs/extmail_access.log;
}

2)创建fcgi.conf

[root@node1 ~]# vi /usr/local/nginx/conf/fcgi.conffastcgi_param  GATEWAY_INTERFACE  CGI/1.1;fastcgi_param  SERVER_SOFTWARE    nginx;fastcgi_param  QUERY_STRING       $query_string;fastcgi_param  REQUEST_METHOD     $request_method;fastcgi_param  CONTENT_TYPE       $content_type;fastcgi_param  CONTENT_LENGTH     $content_length;fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;fastcgi_param  REQUEST_URI        $request_uri;fastcgi_param  DOCUMENT_ROOT      $document_root;fastcgi_param  SERVER_PROTOCOL    $server_protocol;fastcgi_param  REMOTE_ADDR        $remote_addr;fastcgi_param  REMOTE_PORT        $remote_port;fastcgi_param  SERVER_ADDR        $server_addr;fastcgi_param  SERVER_PORT        $server_port;fastcgi_param  SERVER_NAME        $server_name;

3)重启nginx

[root@node1 ~]# service nginx restart

——Extmail测试

  管理后台  用户名:root@test.com  初始密码:extmail*123*

 extmail用户登录界面

注册账号后登陆报错:

Can't chdir to /var/mailbox/test.com/fei.xiao/Maildir/, No such file or directory

解决方案:

目录权限属性问题:

查看extman的:
SYS_MAILDIR_BASE = /var/mailbox
配置是否正确,删除域名再重建,在新建用户的时候会自动在/var/mailbox/下创建该用户的域名和邮件目录

Nginx相关问题:系统启动后,登陆界面报错:502 Bad Gateway

查看nginx的erro日志:

(13: Permission denied) while connecting to upstream:[nginx]

解决方法:

setsebool httpd_can_network_connect on

open() "/var/www/extsuite/extmail/html/favicon.ico" failed (2: No such file or directory)

解决方法:

setenforce 0

服务启动脚本:

[root@extmail ~]# cat start_extmail.sh systemctl stop firewalldsetenforce 0/var/www/extsuite/extmail/dispatch-init start/var/www/extsuite/extman/daemon/cmdserver -v -dservice courier-authlib restartservice nginx restartcd /usr/sbin/ && ./postfix start ./dovecot -F

nginx 413 client intended to send too large body

解决方法:
