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

MIN_OUTGOING_CONFIRMATIONS=2
LINK_CONTRACT_ADDRESS=0xa36085F69e2889c224210F603D836748e7dC0088

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 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.
