如何在单独的主机中配置Rocket Chat和MongoDB

Question

我正在尝试在单独的主机中安装和配置rocketchat和mongodb。一个用于应用程序，另一个用于mongodb。我遵循本教程https://rocket.chat/docs/installation/manual-installation/ubuntu/

我分别完成了每个部分的所有步骤(mongodb和rocketchat(

当我运行main.js命令时：

MONGO_URL=mongodb://<mongodb-ip-host>:27017/rocketchat?replicaSet=rs01 MONGO_OPLOG_URL=mongodb://<mongodb-ip-host>:27017/local?replicaSet=rs01 ROOT_URL=http://0.0.0.0:3000 PORT=3000 node /var/Rocket.Chat/main.js

我在下面得到了这个错误：

throw(ex);

}

PS.：我将RocketChat设置为/var/Rocket.Chat文件夹

我想了解为什么应用程序的某些部分试图在mongodb中本地连接：127.0.0.1:27017

Answer 1

我认为问题出在mongodb服务器中的副本集中。它被错误地配置为mongodb服务器的127.0.0.1 IP地址。

您可以在mongodb服务器的外壳中获取此信息。mongo或mongosh，具体取决于您的mongodb版本。我在这里使用mongo，但您可能需要使用mongosh

$ mongo
> rs.conf()

mongojsrs.conf()函数调用的结果应该类似于以下内容：

{
"_id" : "rs01",
"version" : 2,
"protocolVersion" : NumberLong(1),
"writeConcernMajorityJournalDefault" : true,
"members" : [
{
"_id" : 0,
"host" : "127.0.0.1:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"catchUpTimeoutMillis" : -1,
"catchUpTakeoverDelayMillis" : 30000,
"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("<<masked>>")
}
}

请注意，副本集的主机已配置为127.0.0.1:27017

这可以通过在副本集所在的mongo服务器上的mongo shell中执行以下命令来解决。

> cfg = rs.conf()
> cfg.members[0].host = "mongodb-server-ip:27017"
> rs.reconfig(cfg)
