如何开始鸽舍？

Question

我正在构建一个 Web 服务器来托管多个网站。除了邮件服务器，我一切正常。我正在使用 linode 来托管我的 vps，并且我一直在关注他们的教程。仅供参考，我使用的是 Ubuntu 11.10。

这是我一直关注的链接，http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid。我到了告诉我重新启动 dovecot 的部分，所以我尝试了“service dovecot restart”。但后来我得到这个“重启：未知实例：”。我以 root 身份登录，所以我没有使用 sudo。

由于这不起作用，我尝试了“/etc/init.d/dovecot restart”并得到“dovecot 启动/运行，进程 4760”。所以我尝试“/etc/init.d/dovecot status”并得到“dovecot stop/waiting”。

所以我尝试了“service dovecot start”并得到“dovecot start/running, process 4781”。所以我试图获得状态，所以我厌倦了“服务鸽子状态”并得到“鸽子停止/等待”

然后我厌倦了“/etc/init.d/dovecot start”并得到“dovecot start/running, process 4794”。所以我厌倦了获取状态，所以我厌倦了“/etc/init.d/dovecot status”并得到了“dovecot stop/waiting”

只是为了踢球和咯咯笑，我厌倦了杀死进程，我使用了我在执行“service dovecot start”时得到的PID，这是命令“kill -9 4444”，我得到了这个“bash：kill： (4805) - 没有这样的过程”

我做错了吗？

以下是 /var/log/mail.log 中的内容

Answer 1

作为一般提示，请尝试直接在前台运行 dovecot：

鸽舍-F

原因是前台经常会直接将加载错误消息输出到控制台，这通常可以让您快速跟踪通常不记录的错误（例如配置解析错误）。

Answer 2

这意味着它启动，尝试解析配置并失败。在 /var/log 中查找累积 dovecot 日志的日志以确定问题所在。它是哪个日志，取决于您使用的 Linux 发行版。

-- 编辑--

状态 89 表示配置中有错误，与解析器有关。请先查看您是否已终止所有 {} 花括号。这是我的第一个预感。

Answer 3

本教程从 2010 年 5 月 9 日开始。
查看 dovecots 更新日志，您会看到...
v1.2.6 2009-10-05 该日期之前的最后一个 dovecot 版本
v2.0.rc1 2010-07-02 该日期之后的下一个 dovecot 版本

所以本教程可能会使用 1.x 配置，而现在我们将使用 dovecot 2.x。

现在我找到了这个http://wiki2.dovecot.org/Upgrading/2.0
在其他一些信息旁边，它提供了一种将配置从 1.2 转换为 2.0 的方法。

这里有更多关于升级http://wiki2.dovecot.org/Upgrading

虽然（还）我没有解决办法

编辑：（解决方案）

首先，你还需要安装：

apt-get install dovecot-sieve  
apt-get install dovecot-managesieved  
apt-get install dovecot-mysql

如果您愿意，请阅读有关升级旧 1.x 配置的提示 http://wiki2.dovecot.org/Upgrading

我的 dovecot.conf：

log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/home/vmail/%d/%n/Maildir
namespace {
  inbox = yes
  location = 
  prefix = INBOX.
  separator = .
  type = private
}
passdb {
  args = /etc/dovecot/dovecot-sql.conf.ext
  driver = sql
}
protocols = imap pop3
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-master {
    mode = 0600
    user = vmail
  }
  user = root
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
#userdb {
#  args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
#  driver = static
#}
userdb {
  args = /etc/dovecot/dovecot-sql.conf.ext
  driver = sql
}
protocol lda {
  auth_socket_path = /var/run/dovecot/auth-master
  log_path = /home/vmail/dovecot-deliver.log
  mail_plugins = sieve
  postmaster_address = postmaster@example.com
  plugin {
    sieve_global_path = /var/vmail/globalsieverc
    # The include extension fetches the :personal scripts from this 
    # directory. When ManageSieve is used, this is also where scripts 
    # are uploaded.

    sieve_dir = ~/sieve

    # The location of the user's active script:

    sieve = ~/.dovecot.sieve

    # Directory for :global include scripts (for v1.1 include extension)

    sieve_global_dir = /var/vmail/sieve

    sieve_maxscriptsize = 128
  }
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
}

我的 dovecot-db.conf.ext

driver = mysql
connect = host=127.0.0.1 dbname=mail user=mail_admin password=your_password
default_pass_scheme = PLAIN-MD5
#password_query = SELECT email as user, password FROM users WHERE email='%u';
#user_query = SELECT email as user, password, 5000 as uid, 5000 as gid, '/var/vmail/%d/%n' as home FROM view_users WHERE email='%u';
password_query = SELECT email AS user, password, 5000 AS userdb_uid, 5000 AS userdb_gid, '/var/vmail/%d/%n' AS userdb_home FROM users WHERE email = '%u';
user_query = SELECT email AS user, password, 5000 AS uid, 5000 AS gid, '/var/vmail/%d/%n' AS home FROM users WHERE email = '%u';

同时编辑您的/etc/postfix/master.cf，使其包含 smtps（在 465 上使用 SSL/TLS 的 smtp）。我必须激活它才能从我家访问 smtp，因为我的 isp 阻止了端口 25（这很常见）。此外，我更喜欢具有传输层安全性的 smtp。

smtps     inet  n       -       -       -       -       smtpd

然后运行service postfix restart

我通过谷歌搜索收集了有关此的所有信息，但不知道我在哪里，但最后一个问题

2013-01-03 16:43:27 lda: Error: userdb lookup(info@example.com): Disconnected unexpectedly
2013-01-03 16:43:27 lda: Fatal: Internal error occurred. Refer to server log for more information.

我解决了阅读一些http://workaround.org/ispmail/lenny/configure-dovecot
基本上，我发现当你用谷歌搜索你在这里得到的任何错误输出时，你会得到很好的结果：

/home/vmail/dovecot-deliver.log
/var/log/mail.log
/var/log/mail.err
/var/log/syslog

Answer 4

如果 syslog 中没有出现相关消息，并且 dovecot 在 Upstart 下运行，则可能在 /var/log/upstart/dovecot.log 中发现配置错误。

Answer 5

尝试删除 dovecot-postfix 包和 /etc/dovecot/conf.d/99-*.conf 文件 对我有帮助
