Mac OSX 10.13.6
ejabberd 19.05
我使用安装程序安装ejabberd,并在出现提示时输入以下信息:
ejabberd server domain: localhost
administrator username: 7stud
administrator password: blahblah
我正在学习本教程:How to Build One to One Chat App Using Ejabberd & Erlang from Scratch?。
如果我通过单击start
目录中的ejabberd-19.05/bin
可执行文件来启动ejabberd,则ejabberd将启动,并在浏览器中打开一个网页。然后,我可以登录到管理Web界面。
但是,本教程指导我将以下内容添加到ejabberd.yml:
auth_method: sql
sql_type: mysql
sql_server: "localhost"
sql_database: "chat"
sql_username: "root"
sql_password: ""
(对于我的mysql设置,root用户没有密码-我只是在提示输入密码时按回车键)
这样做之后,如果我停止ejabberd,然后再次启动ejabberd,我将无法再登录到管理页面。
我有两个问题:
为什么将数据库配置添加到ejabberd.yml会阻止我登录到管理Web界面?
为什么还要配置mysql db?根据{{3}}:ejabberd default backend is Mnesia internal database
。我非常乐于使用健忘症(不必触摸ejabberd.yml)。
我用ejabberd.yml中的mysql db config东西完成了本教程的其余部分,但没有,但是User1和User2都没有收到其他用户发送的消息,因此由于某种原因,我的ejabberd设置无法正常工作。我还尝试通过遵循ejabberd docs来配置另一个mysql数据库:
auth_method: sql
sql_type: mysql
sql_server: "localhost"
sql_database: "ejabberd"
sql_username: "ejabberd"
sql_password: "12345"
仍然没有运气。
如果有人可以推荐,我愿意尝试使用ejabberd中继消息的其他任何简单教程。

为什么将数据库配置添加到ejabberd.yml会阻止我登录到管理Web界面?
正如Pouriya所说,您首先在Mnesia数据库中创建了一个帐户。然后,您切换到该帐户不存在的MySQL数据库...因此,再次创建它,或使用 export2sql 将Mnesia内容导出到SQL文件并将其导入SQL数据库中。 / p>
为什么还要配置mysql db?根据ejabberd的文档:ejabberd的默认后端是Mnesia内部数据库。我非常乐于使用健忘症(不必触摸ejabberd.yml)。
内部Mnesia数据库足以容纳小型服务器(数百个并发用户)。如果您有一台小型服务器,那可能就足够了。但是,如果您计划使用大型服务器(成千上万的并发用户),则最好使用SQL数据库。现在有可能开始使用Mnesia几个月,一旦有很多用户,就可以将内容和配置切换到SQL。
答案 1 :(得分:1)
我需要在ebjabberd.yml中配置默认的Mnesia数据库吗?我该怎么办?
安装ejabberd,在配置文件中进行任何更改,然后使用Mnesia。
我实际上是否需要能够登录到管理Web界面才能使本教程正常工作?
“上班”是一个模棱两可的句子,所以我无法回答。
我在哪里创建帐户?在Mysql中?在埃贾伯德?
在ejabberd中,就像您存储在Mnesia中的第一个帐户一样。
我有两个用户想要在他们之间传递一条消息,即“ hi”。
对于两个用户...。只需安装ejabberd,在ejabberd中注册两个帐户即可。
