I have yii2 and yii2-redis installed on a CraftCMS project, but when I fire up the project, I get an error message that reads:
Database Exception – yii\db\Exception
Failed to open redis DB connection (tcp://:, database=): 0 - Failed to parse address ":"
Error Info: Failed to parse address ":"
I'm not quite sure what to do with this error. In my .env file, I put in:
REDIS_HOST=localhost
REDIS_PORT=3306
REDIS_PASSWORD=
REDIS_KEY_PREFIX=craft
But that only yielded a different error:
Database Exception – yii\db\Exception
Failed to open redis DB connection (tcp://:3306, database=): 0 - php_network_getaddresses:
getaddrinfo failed: nodename nor servname provided, or not known
Error Info: php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known
Help?
Additional context: I didn't set up the build for this project, so I more or less inherited this Redis setup.
Update:
I went and dug into the config file for the Redis setup and found a misnaming between the .env variables and what was present in the .env file. Now I'm getting a completely different error:
"Received illegal data from redis: Redis command was: SELECT 0"
Please check that your configuration matches the environment variables you use.
Turns out I'd deleted the Redis database (don't remember how or when), so creating a new one (with the correct .env variables set) fixed the problem immediately.
Whew.
I'm struggling to fix my orientdb database. I'm getting the error:
Error: com.orientechnologies.orient.core.exception.ODatabaseException: Error on retrieving record #58:65894 (cluster: cluster_name_here)
I'm running REPAIR DATABASE --fix-graph and that's when i get this error. Is there any other suggestions in approaching this? This is also the case when running CHECK DATABASE
I tried using this link as a resource: https://orientdb.com/docs/last/Console-Command-Repair-Database.html
I am upgrading my heroku database from a hobby dev to Standard 0 (using the official instructions https://devcenter.heroku.com/articles/upgrading-heroku-postgres-databases#upgrade-with-pg-copy-default).
All went well, until I promoted the new database and restarted the app. I then get the following error:
o.s.boot.SpringApplication : Application startup failed
...
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException: Unable to obtain Jdbc connection from DataSource
...
Caused by: org.flywaydb.core.api.FlywayException: Unable to obtain Jdbc connection from DataSource

Caused by: org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "54.xxx.xx.xxx", user "u94bf9vxxxxxx", database "d2mqk0b6xxxxxx", SSL off
...
If I swap back to the old database again, everything works again. The only thing that I am changing is the promoted database.
Is there a difference between connecting to hobby and standard databases that I need to be aware of?
The relevant part of my application.yml looks as follows:
spring:
datasource:
driverClassName: org.postgresql.Driver
url: ${JDBC_DATABASE_URL}
username: ${JDBC_DATABASE_USERNAME}
password: ${JDBC_DATABASE_PASSWORD}
flyway:
enabled: true
locations: classpath:db/migrations
Any suggestions on how I can debug this would be very welcome too.
Looks like you aren't connecting with SSL where it is required by Heroku PostgreSQL installs.
See Herokus documentation on SSL for PostgreSQL.
See also Herokus documentation for enabling SSL on JDBC connections.
You will need to add something like &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory to your JDBC URL.

I am getting invalid database error while trying to use the ORM Composer from github .
The error is like :
You have specified an invalid database connection group (test) in your config/database.php file.
But in config/database.php i have given it clearly. Please help me on that.
I am trying to get started with the salat plugin in playframework. I have configured the database in application.conf and added all the dependencies to Build.scala and added salat to the play.plugins file. I haven't actually added any code to the project yet, I just followed the instructions on the github page, and then tried to run the project. I am getting the following error message
(Server started, use Ctrl+D to stop and go back to the console...)

I am stumped because I added my password and everything to the conf file. From the log it looks as though whatever is trying to connect to the database for me, is not logging in first, using the info I provided.
As you say, it looks like the root issue is that MongoDB is rejecting the command "listDatabases". This command requires administrator access to the MongoDB process since it reveals information about the other databases hosted there.
Unfortunately, the message it returns, "need to login", is a little misleading. You have logged in! You just don't have permission to list the databases.
Here's a simple experiment you can try yourself with the MongoDB shell. See that "show dbs" fails with the same error message you got in your app, but "show collections", which doesn't require access to any other databases outside your own, succeeds?
% mongo ds031907.mongolab.com:31907/heroku_app4620908 -u heroku_app4620908 -p your_password
MongoDB shell version: 2.0.7
connecting to: ds031907.mongolab.com:31907/heroku_app4620908
> show dbs
Fri Aug 17 13:12:10 uncaught exception: listDatabases failed:{ "errmsg" : "need to login", "ok" : 0 }
> show collections
system.indexes
system.users
(Note: I did this with my own MongoLab account and modified the text when copying and pasting here so you could just copy it into your terminal.)
Is there a way to avoid making the listDatabases call? I'm not familiar with the framework you're using.
I've the problem as well...
it should come with the SalatPlugin's onStart method that is requesting all database names: source._2.connection.getDatabaseNames().
This code is just testing the aliveness of the server...
I'm gonna check with leon how we could this differently! Sadly, you won't be able to connect until this will be fixed!
Stay tuned on this issue https://github.com/leon/play-salat/issues/23
This is fixed in the latest version of play-salat, it now uses getCollectionNames instead
use admin
db.addUser('userName', 'userPassword')
db.auth('userName', 'userPassword')
show dbs
java:
DB db = mongo.getDB("YouDBName") ;
db.authenticate("userName", "userPassword".toCharArray()) ;
System.out.println(mongo.getDatabaseNames()) ;
