I have tried everyting to connect my Chainlink node up to my postgresql database with no luck. I have scoured the interwebs for answers to no avail...
Here is the error message I am receiving:
[ERROR] failed to initialize database, got error failed to connect to `host=/tmp user=root database=`: dial error (dial unix /tmp/.s.PGSQL.5432: connect: no such file or directory)
Here is my .env file:
ROOT=/chainlink
LOG_LEVEL=debug
ETH_CHAIN_ID=42
MIN_OUTGOING_CONFIRMATIONS=2
LINK_CONTRACT_ADDRESS=0xa36085F69e2889c224210F603D836748e7dC0088
CHAINLINK_TLS_PORT=0
SECURE_COOKIES=false
GAS_UPDATER_ENABLED=true
ALLOW_ORIGINS=*
ETH_URL=wss://kovan.infura.io/ws/v3/id...
DATABASE_URL=https://chainlink-db-url://postgres:Password#chainlink-kovan:5432
I have tried every configuration of the connection string. Also I am able to connect to the db via pgAdmin no problem and the dbs are publicaly accessible.
The postgresql database is on AWS.
Please change the syntax of your DATABASE_URL to:
DATABASE_URL=postgresql://"username":"password"#"public-ip-pg-server":5432/"database-name"
just change:
"username" : you need to configure a new user, because the default/admin user postgres will not work for it.
"password" : password of the user
"public-ip-pg-server" : the public ip address of your postgresql-server
"database-name" : the name of your database
PS: delete all " in your syntax (;
Here is the link to the official documentation: https://docs.chain.link/docs/connecting-to-a-remote-database/

I tried to connect with
*mongo "mongodb+srv://cluster0.mi3o1.mongodb.net/test" --username cristian* in the shell.
But instead, it looks like it's trying to connect with:
*mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb*
I am getting the error
*Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: No connection could be made because the target machine actively refused it. :

exception: connect failed
exiting with code 1
bash: mongodb+srv://cluster0.mi3o1.mongodb.net/test: No such file or directory*
I have created the cluster, database access with admin role user cristian, whitelisted both my IP and all IPs 0.0.0.0/0, created a new database, loaded sample databases, opened ports 27015,27016,27017 and tested on portquiz.net.
I added a PRTSCN.
Please help!
terminal prtscn
Thank you very much D. SM for your help, it looks like it was a problem with my .bash_profile. When i did the copy and paste for the 2 paths i dont know why the terminal writed the last " on another row and got some spaces between. I rewrited the 2 rows with no space like this:
alias mongod="/c/Program\ files/MongoDB/Server/4.4/bin/mongod.exe"
alias mongo="/c/Program\ Files/MongoDB/Server/4.4/bin/mongo.exe"
and it worked.
I'm trying to use the new gorm v2 implementation with Postgresql (I use Docker for the Golang app and for Postgres). I tried to do it as shown in the gorm documentation.
That gave me the following error:
web_1 | 2020/09/19 19:25:57 /go/src/caiqueservice/main.go:36 failed
to connect to host=/tmp user=admin database=caique: dial error (dial
unix /tmp/.s.PGSQL.5432: connect: no such file or directory)
So since the documentation didn't specify host, but the error message set that to /tmp I set that value.
dsn := fmt.Sprintf("host=%v user=%v password=%v dbname=%v port=%v sslmode=disable",
os.Getenv("DB_HOST"),
os.Getenv("DB_USERNAME"),
os.Getenv("DB_PASSWORD"),
os.Getenv("DB_DATABASE"),
os.Getenv("DB_PORT"),
)
db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
.env
DB_HOST=localhost
DB_PORT=5432
DB_DATABASE=caique
DB_USERNAME=admin
DB_PASSWORD=password
Doing so gives me the following error message:
web_1 | 2020/09/19 19:36:47 /go/src/caiqueservice/main.go:36 failed
to connect to host=localhost user=admin database=caique: dial error
(dial tcp [::1]:5432: connect: cannot assign requested address)
The postgres db is reachable by pgadmin.
I don't know what to do next and help would be very much appreciated.
Inside a container, localhost refers to the container itself, not to the host machine. If you are using docker-compose, you should be able to connect to the postgres container (from the app container) using the postgres container name as the host name. If you are running both containers separately, you will need to connect them to the same docker network or link them.
I have installed mongodb in different server. I have modified my old code
db: 'mongodb://localhost/dev',
to new code
my username : proUseAdd
password : mongodb#23
ip : 169.213.64.127
I modified like this
db: 'mongodb://proUseAdd:mongodb#23#169.213.64.127:27017/dav',
I am getting this error
Could not connect to MongoDB!
Error: failed to connect to
[23#169.213.64.127:27017]
UPDATE
i have tried changed my password:mongodb23
query strin:
db: 'mongodb://proUseAdd:mongodb23#169.213.64.127:27017/dav',
still i'm getting error
Could not connect to MongoDB!
Error: failed to connect to
[169.213.64.127:27017]
Change your password to something which doesn't contain #.
While parsing your connection string, MongoDB driver looks for the # character to separate your credentials and the host name. Since your password has an # in it, it recognizes your credentials as proUseAdd:mongodb and your host name as 23#169.213.64.127:27017.
I am trying to use mongoDB MMS backup functionality. I am getting the following error when trying to connect in the "Add Host" part of the wizard.
Unable to detect host within check interval.
I have MongoDB 2.6.4 on a my Windows 7 laptop. I've created an admin user with the following privileges:
> db.createUser(
... {
... user: "admin",
... pwd: "xxx"
... roles: [
... "clusterAdmin",
... "readAnyDatabase",
... "dbAdminAnyDatabase",
... "userAdminAnyDatabase"
... ]
... }
... );
I run mongod --auth.
Now I try to connect via MMS using MONGODB-CR Auth mechanism and get the error I described above.
In the log I get many errors like the following:
[2014/10/21 09:13:59] [monitoring.info] [monitoring-agent/components/agent.go:551]

Using Robomongo 0.8.4 client I was able to log-in using the user and pass.
I want to be able for MMS to connect to my local machine and initialize a backup of the databases on my machine.
Thanks in advance.
I had this error while configuring my mongodb-mms. On my Ops Manager server I had configured my TLS connections correctly, but on the mongo server being monitored I had the incorrect TLS certificate. The log /var/log/mongodb-mms-automation/monitoring-agent.log on the agent I was trying to monitor helped me out:
[2020/04/26 02:05:47.363] [discovery.collector-mongo2:27017.error] [components/discovery.go:contexts:580] Discovery commands requiring authentication will be skipped.
Failed to get connectionStatus. Err: `auth error: round trip error: (UserNotFound) Could not find user "CN=mms,OU=TestClientCertificateOrgUnit,O=TestClientCertificateOrg,L=TestClientCertificateLocality,ST=TestClientCertificateState,C=US" for db "$external"`

See this page to add in your mms user so that the user can authenticate correctly (or fix your certs if it's just a mixup).
I've installed propel bundle for symfony2.
my database configuration is:
propel:
dbal:
driver: pgsql
user: postgres
password: postgres
dsn: pgsql:host=localhost;port=5432;dbname=test_database
options: {}
attributes: {}
When i wan to create this database from console (console propel: database:create) i have got strange error : Unable to open PDO connection [wrapped: SQLSTATE[08006] [7] FATAL: database "pgsql" does not exist.
i created pgsql database on my localhost and everything was good. Database "test_database" was succesfull created. Can somebody explain me why i got this previous error? On mysql i've created database without any problems.
This issue was a bug in the PropelBundle, it has been fixed by the following commit (even if the commit message is about MySQL, it fixes other RDBMS): https://github.com/propelorm/PropelBundle/commit/b4475d27fb1eb846d10cc2d2e2bd164f037508e3
I 've installed new PropelBundle via Composer and everything is ok now. I think maybe it was a problem with 1.0 bundle , now I have 1.1
