Roundcube 问题：与存储服务器的连接失败答案

【问题标题】：Roundcube issue : connection to storage server failedRoundcube 问题：与存储服务器的连接失败
【发布时间】：2013-03-13 17:20:41
【问题描述】：

我在 Roundcube 中收到此错误（“连接到存储服务器失败”）行。我已经检查了所有内容，配置和数据库用户名密码，服务器详细信息都是干净的。谁能告诉我可能是什么问题？这里我给出了整个配置文件。

【解决方案1】：

尝试打开所有调试选项并直接与 IMAP 服务器对话，而不涉及 RoundCube，请参阅 this guide。这样您就可以在尝试让 RoundCube 工作之前确定您的 IMAP 服务器正在工作。

【讨论】：

【解决方案2】：

一些 Devcot 配置文件已损坏。所以你需要通过重新创建新的配置文件并删除现有的来修复。通过putty软件SSH登录root

执行这些代码

cd /home
/etc/init.d/dovecot stop
rm -f */imap/*/*/Maildir/dovecot*
rm -f */imap/*/*/Maildir/.*/dovecot*
rm -f */Maildir/dovecot*
rm -f */Maildir/.*/dovecot*
/etc/init.d/dovecot restart

现在您可以登录到您的网络邮件应用程序。不会出现错误。

【讨论】：

我的/etc/init.d/dovecot 不存在。

【解决方案3】：

这意味着鸽舍没有运行。

运行sudo dovecot

这是我在沮丧数小时后得到的解决方案

【讨论】：

这应该是公认的答案。还包括一些关于使用 systemctl status dovecot 检查 dovecot 配置文件中的错误

【解决方案4】：

您应该删除到 dovecot 邮件服务器并使用另一个邮件服务，两个服务可能是冲突的，因此您必须删除一个邮件服务，我已经尝试了 2 天这个错误。

代码：yum remove dovecot

如果您使用此代码 Dovecot 会从您的服务器中删除并且没有冲突

【讨论】：

【解决方案5】：

我在迁移到新服务器后遇到了同样的问题，我彻底检查了配置显示我的 IMAP 和 IMAPS 被禁用，我只是启用了这两个服务并重新启动服务器。

【讨论】：

【解决方案6】：

通过运行编辑 15-mailboxes.conf

nano /etc/dovecot/conf.d/15-mailboxes.conf

在命名空间收件箱 {} 块内添加以下文本：

namespace inbox {
    inbox = yes
...

保存文件并运行：

service dovecot restart

你就完成了..！

【讨论】：

【解决方案7】：

这就是你修复它的方法：

查看日志： tail /var/log/dovecot.log

如果你看到：

致命：未知的数据库驱动程序“mysql”

意思是缺少包！ Dovecot 需要 dovecot-mysql 包来运行 mysql 身份验证。用yum安装就可以解决这个问题：

yum install dovecot-mysql

【讨论】：

【解决方案8】：

一个可能的原因是您的 Dovecot 安装不工作。更改mysql版本后发生在我身上。我必须这样做：

sudo apt-get install dovecot-mysql
sudo service dovecot restart

然后它起作用了。

【讨论】：

【解决方案9】：

我从 Debian Jessie 升级到 Stretch 时遇到了这个问题。我查看了日志：

/var/log/syslog

发现问题是我明确禁用了协议SSLv2，不再支持它。我从协议列表中删除了它，一切正常。

我最近在成功安装roundcube后遇到了同样的问题

首先我尝试了这两个命令行：

netstat -tulpn | grep :143

telnet localhost 143

我收到连接被拒绝错误消息。

所以我必须安装telnet

apt-get install telnetd

安装成功后运行Restarts

/etc/init.d/openbsd-inetd restart

/etc/init.d/dovecot restart

然后再次运行

 netstat -tulpn | grep :143

结果

tcp        0      0 0.0.0.0:143             0.0.0.0:*               LISTEN      13439/dovecot
tcp6       0      0 :::143                  :::*                    LISTEN      13439/dovecot

尝试第二次测试运行

telnet localhost 143

结果

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE START TLS AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready.

【解决方案11】：

我遇到了同样的问题，我通过以下方式找到了解决方案。

我已经通过以下命令检查了日志。

tail /var/log/dovecot.log

通过使用上述命令，我在日志中发现了以下错误。

9 月 1 日 10:39:50 imap(mail@yourdomain.com)：错误：用户 mail@yourdomain.com：初始化失败：初始化邮件存储从 mail_location 设置失败： mkdir(/var/vmail/yourdomain.com/mail) 失败：权限被拒绝 (euid=101(vmail) egid=12(mail) missing +w perm: /var/vmail, dirowned 通过 4325:4319 模式=0751)

所以我注意到服务器无法创建名为“yourdomain.com”的目录，它需要“+w”权限。我还注意到“yourdomain.com”目录需要所有权“vmail:mail”。

最后，使用以下命令创建了目录。

cd /var/vmail/;
mkdir yourdomain.com;
chown vmail:mail yourdomain.com -R;
chmod +w yourdomain.com;

就是这样。

我希望这个答案可以帮助你。

【解决方案12】：

删除下面的文件并登录。

/etc/dovecot/conf.d/15-mailboxes.conf

或使用

sudo rm -rf nano /etc/dovecot/conf.d/15-mailboxes.conf

【讨论】：

【解决方案13】：

我可以通过参考 Dovecot Status 解决此问题。

首先，确保您没有使用隐身浏览器窗口，然后通过运行此命令检查 Dovecot 状态

service dovecot status

它会告诉你：

    ● dovecot.service - Dovecot IMAP/POP3 email server
   Loaded: loaded (/lib/systemd/system/dovecot.service; enabled; vendor preset: enabled)
   Active: **inactive** (dead) since Mon 2020-03-30 21:03:32 UTC; 29min ago
     Docs: man:dovecot(1)
           http://wiki2.dovecot.org/
 Main PID: 910 (code=exited, status=0/SUCCESS)

然后运行service dovecot start

【讨论】：

【解决方案14】：

我在 Ubuntu 20.04 上设置 iRedMail dockerized 版本时遇到了类似的问题。

问题是当我使用命令 - service dovecot status 检查时，Dovecot 没有在容器中运行。当我尝试使用命令启动服务时 - service dovecot start 我得到了错误

root@mail:/var/spool/postfix# service dovecot start    
 * Starting IMAP/POP3 mail server dovecot
Error: bind(/var/spool/postfix/private/dovecot-auth) failed: No such file or directory
Fatal: Failed to start listeners

我还运行了以下命令来确认我的鸽舍配置是否正常：

dovecot -n

是的，该命令的输出表明它很好。

这是我修复它的方法：

这个问题是由于 Postfix 没有在我的容器中安装/运行引起的，我在使用 docker logs container-id 检查容器的 docker 日志时发现了这一点。 Dovecot 引用的文件 /var/spool/postfix/private/dovecot-auth 应该由 Postfix 创建，但是，因为安装 Postfix 的脚本失败，因为正确的构建 iRedMail 图像时未选择脚本路径，然后出现此问题，因为 Dovecot 找不到文件 /var/spool/postfix/private/dovecot-auth:

[iRedMail] [Entrypoint] /docker/entrypoints/postfix.sh 
/docker/entrypoints/functions.sh: line 113: /docker/entrypoints/postfix.sh: No such file or directory
[iRedMail] [Entrypoint] /docker/entrypoints/mlmmj.sh 
[iRedMail] [Entrypoint] /docker/entrypoints/mlmmjadmin.sh 
[iRedMail] [Entrypoint] /docker/entrypoints/iredapd.sh 
[iRedMail] [Entrypoint] /docker/entrypoints/antispam.sh 
mail: cannot send message: Process exited with a non-zero status

我所要做的就是使用 git clone -b stable https://github.com/iredmail/dockerized 为 iRedMail 拉取 docker 存储库，使用 docker build . --tag iredmail:latest -f dockerized/Dockerfiles/Dockerfile 在我的本地重建映像，然后运行它。这次选择了我的 Postfix 安装脚本的正确位置，并且 Postfix 安装和设置运行良好。

当我再次使用 Dovecot 服务检查时：

service dovecot start

它告诉我它运行良好。

就是这样
