问题描述
我正在尝试设置replicaset，但初始化时遇到问题。
我第一次跑步
id_ = "1294917318405836802"
exp_tweet = api.get_status(id_,tweet_mode = 'extended')
content = exp_tweet._json
然后每次
db_1 | uncaught exception: Error: Couldn't add user: not master
我的设置是：
/ docker-compose.yml
db_1 | {"t":{"$date":"2020-09-16T16:06:05.341+00:00"},"s":"I","c":"ACCESS","id":20249,"ctx":"conn1","msg":"Authentication Failed","attr":{"mechanism":"SCRAM-SHA-256","principalName":"user","authenticationDatabase":"admin","client":"172.18.0.5:37916","result":"UserNotFound: Could not find user \"user\" for db \"admin\""}}
db_1 | {"t":{"$date":"2020-09-16T16:06:05.342+00:00"},"attr":{"mechanism":"SCRAM-SHA-1","result":"UserNotFound: Could not find user \"user\" for db \"admin\""}}

感谢您的帮助！
解决方法
您可以通过在docker-compose中使用基本mongo映像来实现此目的
您的设置应如下所示：
/ docker-compose.yml
version: "3.0"
services:
# Worker 1
mongo1:
image: mongo:latest
volumes:
- ./replicaSetup:/opt/keyfile
- mongodata:/data/db
environment:
MONGO_INITDB_ROOT_USERNAME: user
MONGO_INITDB_ROOT_PASSWORD: xxxx
ports:
- 27017:27017
command: 'mongod --auth --keyFile /opt/keyfile/shared.key --replSet amsdb'
# Worker 2
mongo2:
image: mongo:latest
volumes:
- ./replicaSetup:/opt/keyfile
- mongodata2:/data/db
environment:
MONGO_INITDB_ROOT_USERNAME: user
MONGO_INITDB_ROOT_PASSWORD: xxxx
ports:
- 27018:27017
command: 'mongod --auth --keyFile /opt/keyfile/shared.key --replSet amsdb'
# Worker 3
mongo3:
image: mongo:latest
volumes:
- ./replicaSetup:/opt/keyfile
- mongodata3:/data/db
environment:
MONGO_INITDB_ROOT_USERNAME: user
MONGO_INITDB_ROOT_PASSWORD: xxxx
ports:
- 27019:27017
command: 'mongod --auth --keyFile /opt/keyfile/shared.key --replSet amsdb'
volumes:
mongodata:
mongodata2:
mongodata3:
/ plicateSetup / Dockerfile -保持不变
/plicatorSetup/setup.sh -保持不变
/plicateSetup/replicaSet.js
rsconf = {
_id : "amsdb",members: [
{ _id : 0,host : "172.17.0.1:27017",priority:1 },{ _id : 1,host : "172.17.0.1:27018",{ _id : 2,host : "172.17.0.1:27019",priority:1 }
]
}
rs.initiate(rsconf);
rs.conf();
在撰写本文时，“ mongo：latest”解析为v4.4.1。答案是针对该版本的entrypoint.sh https://github.com/docker-library/mongo/blob/master/4.4/docker-entrypoint.sh
为了处理MONGO_INITDB_ROOT_ *环境变量并将用户添加到数据库，应该以独立模式启动数据库。看来当前的实现不支持.conf文件中的副本集配置，而仅通过命令行参数来支持。
要么在Dockerfile command: "--bind_ip_all --replSet amsdb --port 34000 ... etc"中传递参数，要么为docker-entrypoint.sh创建PR以支持docker.conf
