Ubuntu之Gitlab、Gerrit、Jenkins协调工作配置之部分一：邮箱配置

前提

系统为 Ubuntu , 版本为14.04, 其他版本问题应该不大

系统 hostname 为 zjc - 详见设置linux主机名 —– 此步非必须

$ sudo su

# echo zjc > /etc/hostname

# exit

系统IP地址为

10.1.6.49

一些地址映射 要加入/etc/hosts文件或者DNS

$ sudo apt-get install vim

$ sudo vim /etc/hosts

#自然，也可以用其他文本编辑器

#新添加的项
10.1.6.49      zjc zjc.com vzjc.com  mail.vzjc.com

修改完毕后最好重启一下机器

$ sudo shutdown -r now

安装依赖包

$ sudo apt-get install openssl telnet libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql1

安装mysql

$ sudo apt-get install mysql-client mysql-server

首次安装后会提示输入mysql密码，输入确认并记住，以后还需要用到

设置MySQL数据库

其中的

mail_admin

和

password-for-mail_admin

为生成的数据库mail的用户名和密码，可以修改成自己的，但是一旦修改，后文中出现的地方都要修改。

$ mysql -u root -p
Enter password: input your password
mysql> CREATE DATABASE mail;
mysql> USE mail;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mail.* TO 'mail_admin'@'localhost' IDENTIFIED BY 'password-for-mail_admin';
mysql> GRANT SELECT, INSERT, UPDATE, DELETE ON mail.* TO 'mail_admin'@'127.0.0.1' IDENTIFIED BY 'password-for-mail_admin';
mysql> FLUSH PRIVILEGES;
mysql> CREATE TABLE domains (domain varchar(50) NOT NULL, PRIMARY KEY (domain) );
mysql> CREATE TABLE forwardings (source varchar(80) NOT NULL, destination TEXT NOT NULL, PRIMARY KEY (source) );
mysql> CREATE TABLE users (email varchar(80) NOT NULL, password varchar(20) NOT NULL, PRIMARY KEY (email) );
mysql> CREATE TABLE transport ( domain varchar(128) NOT NULL default '', transport varchar(128) NOT NULL default '', UNIQUE KEY domain (domain) );
mysql> quit

安装Postfit及相关

$ sudo apt-get install postfix postfix-mysql postfix-doc mailutils

如果postfit弹出设置界面，那么General type of mail configuration 选择 Internet Site
System Mail Name 选择 vzjc.com

配置Postfit

虚拟domain配置文件

$ sudo vim /etc/postfix/mysql-virtual_domains.cf

user = mail_admin
password = password-for-mail_admin
dbname = mail
query = SELECT domain AS virtual FROM domains WHERE domain='%s'hosts = 127.0.0.112345

虚拟forwarding配置文件

$ sudo vim /etc/postfix/mysql-virtual_forwardings.cf

user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT destination FROM forwardings WHERE source='%s'hosts = 127.0.0.112345

虚拟mailbox配置文件

$ sudo vim /etc/postfix/mysql-virtual_mailboxes.cf

user = mail_admin
password = password-for-mail_admin
dbname = mail
query = SELECT CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') FROM users WHERE email='%s'hosts = 127.0.0.112345

虚拟email2email配置文件

$ sudo vim /etc/postfix/mysql-virtual_email2email.cf

user = mail_adminpassword = password-for-mail_admindbname = mailquery = SELECT email FROM users WHERE email='%s'hosts = 127.0.0.112345

设置权限

$ sudo chmod o= /etc/postfix/mysql-virtual_*.cf
$ sudo chgrp postfix /etc/postfix/mysql-virtual_*.cf12

建立用户

$ sudo groupadd -g 5000 vmail
$ sudo useradd -c 'VMail' -g vmail -u 5000 vmail -d /home/vmail -m12

使用postconf配置

此处有个需要注意的地方mynetworks应该包含本机的所有IP地址,例如我这里只有一个10.1.6.197,不然会导致发给自己的域的邮件接收不到。如果还是接收不到，那么重启机器看看

postconf -e 'myhostname = vzjc.com'postconf -e 'mydestination = vzjc.com, localhost, localhost.localdomain'postconf -e 'mynetworks = 127.0.0.0/8, 10.1.6.197'postconf -e 'message_size_limit = 30720000'postconf -e 'virtual_alias_domains ='postconf -e 'virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf'postconf -e 'virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf'postconf -e 'virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf'postconf -e 'virtual_mailbox_base = /home/vmail'postconf -e 'virtual_uid_maps = static:5000'postconf -e 'virtual_gid_maps = static:5000'postconf -e 'smtpd_sasl_auth_enable = yes'postconf -e 'broken_sasl_auth_clients = yes'postconf -e 'smtpd_sasl_authenticated_header = yes'postconf -e 'smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination'postconf -e 'smtpd_use_tls = yes'postconf -e 'smtpd_tls_cert_file = /etc/postfix/smtpd.cert'postconf -e 'smtpd_tls_key_file = /etc/postfix/smtpd.key'postconf -e 'proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps'postconf -e 'virtual_transport = dovecot'postconf -e 'local_transport = dovecot'123456789101112131415161718192021

为postfix创建证书

$ cd /etc/postfix
$ sudo openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout smtpd.key -keyform PEM -days 3650 -x50912

更改证书权限

$ sudo chmod o= /etc/postfix/smtpd.key

配置saslauthd

$ sudo mkdir -p /var/spool/postfix/var/run/saslauthd
$ sudo cp -a /etc/default/saslauthd /etc/default/saslauthd.bak12

$ sudo vim /etc/default/saslauthd

设置权限

$ sudo chmod o= /etc/pam.d/smtp
$ sudo chmod o= /etc/postfix/sasl/smtpd.conf12

重启服务

$ sudo adduser postfix sasl
$ sudo service postfix restart
$ sudo service saslauthd restart123

安装dovecot及相关

安装dovecot

$ sudo apt-get install dovecot-common dovecot-imapd dovecot-pop3d dovecot-mysql

弹出的选项中选择生成根证书，并且生成的证书dovecot.pem应该在/etc/dovecot/下面，key在/etc/dovecot/private下面。请确认这一点
hostname 填写 vzjc.com

配置dovecot

$ sudo vim /etc/postfix/master.cf

取消submission配置的注释：

submission inet n       -       -       -       -       smtpd
-o syslog_name=postfix/submission  -o smtpd_tls_security_level=encrypt  -o smtpd_sasl_auth_enable=yes  -o smtpd_client_restrictions=$mua_client_restrictions  -o milter_macro_daemon_name=ORIGINATING123456

文件末尾增加

dovecot   unix  -       n       n       -       -       pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

$ sudo cp -a /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf.bak

清空文件/etc/dovecot/dovecot.conf，加入如下

$ sudo vim /etc/dovecot/dovecot.conf

: 1,$d

注意

ssl_cert

,

ssl_key

指向的证书和私钥必须存在

log_timestamp = "%Y-%m-%d %H:%M:%S "mail_location = maildir:/home/vmail/%d/%n/Maildir

dovecot-sql.conf

$ sudo cp -a /etc/dovecot/dovecot-sql.conf /etc/dovecot/dovecot-sql.conf.bak

$ sudo vim /etc/dovecot/dovecot-sql.conf

driver = mysql
connect = host=127.0.0.1 dbname=mail user=mail_admin password=password-for-mail_admin
default_pass_scheme = CRYPT
password_query = SELECT email as user, password FROM users WHERE email='%u';1234

$ sudo service dovecot restart

$ sudo chgrp vmail /etc/dovecot/dovecot.conf

$ sudo chmod g+r /etc/dovecot/dovecot.conf

设置mail aliases - 详见aliases配置文件 – 这个是给sendmail程序用的吧，反正我是没看出来为啥要配置它

$ sudo vim /etc/aliases

postmaster: root
root:admin@vzjc.com

测试

添加邮件账户

$ mysql -u root -p
Enter password: input your password
mysql> USE mail;
mysql> INSERT INTO domains (domain) VALUES ('vzjc.com');
mysql> INSERT INTO users (email, password) VALUES ('test1@vzjc.com', ENCRYPT('password-for-test1'));
mysql> INSERT INTO users (email, password) VALUES ('test2@vzjc.com', ENCRYPT('password-for-test2'));
mysql> INSERT INTO users (email, password) VALUES ('admin@vzjc.com', ENCRYPT('111111'));
mysql> quit

本来以为用户名可以用 test1 形式， 而不用 test1@vzjc.com 形式呢，结果如果不加@时候收发邮件是时灵时不灵的。。。不测试了，用户名直接加域名得了

重启机器

做完上面操作后如果用

telnet vzjc.com 587

，则显示不能连接，机器重启后就可以了 – 原因待查

$ sudo shutdown -r now

用telnet测试

$ telnet vzjc.com 587

用客户端测试

可以用ubuntu的thunderbird或者其他系统的outlook，foxmail等客户端测试，如果是其他机器上，注意一系列端口号一定要被服务器开放
