This is my first time using Mongodb, It connect normally using the IDE from Mongodb university basics m001 course but when I tried to connect from cmd it won't connect and gives me this error
*** You have failed to connect to a MongoDB Atlas cluster. Please ensure that your IP whitelist allows connections from your network.
Error: Authentication failed. :
connect#src/mongo/shell/mongo.js:374:17 #(connect):2:6 exception:
connect failed exiting with code 1
I added the path to my environment & checked the network access from my Atlas and I can connect to it from anywhere
Can anyone help me with this please??
I'm trying to create a jdbc-connection-pool using payara on the console. Using ./asadmin on Payara_Server/bin/
It is Running on Linux and the credentials for the database are user=jc and password=hola123 (dummies), It is for sure this credentials work. I tried them on Mariadb.
I create a connection pool using ./asadmin on Payara, it looks like this:
./asadmin create-jdbc-connection-pool --datasourceclassname org.mariadb.jdbc.MariaDbDataSource
--restype javax.sql.DataSource --property user=jc:password=hola123:DatabaseName=cinev2:ServerName=localhost:port=3306 cinePool
Now, when I try:
./asadmin ping-connection-pool
I get an error like this:
remote failure: Ping Connection Pool failed for cinePool.
Connection could not be allocated because:
Access denied for user 'jc'#'localhost' to database 'cinev2' Please check the server.log for more details.
Command ping-connection-pool failed.
What would be the causes of this Issue other than Credentials? I have checked if the credentials are right and they are, So I've no clue on the issue.
Since it works when locally connecting to the DB it probably really is an access issue.
Please check if you did all steps outlined here: Access denied for user 'root'#'localhost' (using password: YES) after new installation on Ubuntu
I have a Laravel application running on Google Compute Engine instance. I have configured it to connect to a Cloud SQL database Instance, when I SSH to the VM and run php artisan migrate everything runs smoothly. But when I open the application in a browser I get this Error SQLSTATE[HY000] [2002] Permission denied I cant figure out what is going wrong here, I have tried cloud sql proxy but still the application cant establish a DB connection when accessed from a browser. Can anyone figure out the cause of this weird behavior.
I solved this by enabling httpd_can_network_connect_db flag in selinux by running this command.
sudo setsebool -P httpd_can_network_connect_db=1
I also faced another issue with SELinux with redis and solved it by running this command.
sudo semanage port -m -t http_port_t -p tcp 6379
I have a Play 2.3 app in Java. For this app, I am able to connect to local Postgres server.
But I am unable to connect to Heroku Postgres server.
I have following settings in my application.conf:
db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://ec2test.amazonaws.com:5432/rwerwerwer"
db.default.user=eerwerwerer
db.default.password="5345fdwfdsvfvsdfsdfds"
I am getting following error:
Caused by: org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for ho
st "172.56.17.147", user "eerwerwerer", database "rwerwerwer", SSL off
From PgAdim III, I am able to successful connect to Heroku database.
While adding heroku config, I got:
**! No app specified.**
Follow these steps.
Things to remember:
Use Heroku commands from inside your main directory.
Use database connection as:
db.default.driver=org.postgresql.Driver
db.default.url=${?DATABASE_URL}
No need for username and password.
No need for Procfile.
I'm trying to perform a relatively trivial task: I want to connect to a Heroku database. I have created the database and have been issued credentials from the Heroku site. However, when I try to connect to this database using anything besides the terminal 'heroku' command line client, I get fatal errors or cannot connect errors.
The two tools that I tried to connect with outside of the Heroku terminal application are: Navicat and IntelliJ.
The error that I receive in Navicat when trying to connect to the database is:
could not connect to server: Host is down
Is the server running on host "ec2-107-21-112-215.compute-1.amazonaws.com" and accepting
TCP/IP connections on port 5432?
My connection settings are as follows:
Connection Name Heroku Dev Test
Host Name/IP Address ec2-107-21-112-215.compute-1.amazonaws.com
Port 5432
Navicat doesn't even seem to be making an attempt to connect to that hostname.
When I try to connect with IntelliJ, using the full credentials, I get the following error:
java.sql.SQLException: FATAL: no pg_hba.conf entry for host "75.168.4.146", user "rphbqggxeokuxl", database "dc008iqk0rq4j5", SSL off
Again, I'm using the credentials that the Heroku application provides me with when accessing my database on their website.
Has anyone ran into this Heroku connection issue before?
I also had the issue with the FATAL: no pg_hba.conf entry for host error message.
I solved the connection issue to my Heroku Postgres database by adding the following to my JDBC string: &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory.
Example
jdbc:postgresql://host:port/database?user=username&password=secret&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
You will need the SSL option only if SSL is enabled for your Postgres database (which is the default).
Hint
If you want to check your database connection properties, then just run the following command with the Heroku Toolbelt: heroku pg:info --app your-heroko-appname (make sure that you have Postgres insalled to run this command in your terminal)
The pg:info command will also tell you that sslmode is set to require.
To test the database connection I recommend SQL Power Architect as it is the tool which I was using to check my solution.
Heroku provides this information for connecting from external sources:
https://devcenter.heroku.com/articles/heroku-postgresql#external-connections-ingress
The second error message indicates PostgreSQL is not configured to accept the connection you're trying to make. Given the information Heroku provides, a good guess is that you're not connecting with SSL. Try to enable that on your connection.
Here are instructions for using SSL with Navicat: http://mirror.navicat.com/manual/online_manual/en/navicat/rv_manual/ClientCert.html.
This may be helpful in configuring Intellij to use SSL: https://devcenter.heroku.com/articles/connecting-to-relational-databases-on-heroku-with-java#connecting-to-a-database-remotely.
IntelliJ -> Datasources and Drivers
After you've configured the host, database and user details under the General tab switch to the Advanced tab and ensure that you've added the following:
ssl = true
sslfactory = org.postgresql.ssl.NonValidatingFactory
sslmode = require
You may consider setting a ENVIRONMENT CONFIG VARIABLE 'PGSSLMODE' to 'require' via Heroku's web interface or CLI.
Case: Postgres dB set up as a Heroku add-on and attached to app on a Heroku Dyno.
Heroku's instructions unfortunately leave out any mention of how to activate SSL, even though it is required for any dB tier starting with Standard-0 by default.
Follow all of the pg-copy or pg-upgrade steps (preferred approach depends on your version of Postgres) in Heroku instructions; however, before decommissioning the old database (if relevant) -- add the PGSSLMODE environment variable.
The instructions sufficiently cover how to promote the new database (and, consequently set the DATABASE_URL), so no changes/modifications to them should be required.
Wanted to help others who might run into this.
If you're supplying the Username and Password in seperate fields rather than on the command line, you need to use a ? between the database name and ssl=true and discard the first &
jdbc:postgresql://host:port/database?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
That's the command line that finally allowed me to connect to a PostgreSQL database using SQL Power Architect
For those who might be using Spring Boot and having the configuration provided through the DATABASE_URL environment property (not system property), the suffix can be added to the property:
?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
and passed through with a slight modification to the config bean:
#Bean
public BasicDataSource dataSource() throws URISyntaxException {
URI dbUri = new URI(System.getenv("DATABASE_URL"));
String username = dbUri.getUserInfo().split(":")[0];
String password = dbUri.getUserInfo().split(":")[1];
StringBuilder dbUrl = new StringBuilder(128);
dbUrl.append("jdbc:postgresql://")
.append(dbUri.getHost()).append(":")
.append(dbUri.getPort())
.append(dbUri.getPath());
String query = dbUri.getQuery();
if (null != query && !query.isEmpty()) {
dbUrl.append("?").append(query);
}
BasicDataSource basicDataSource = new BasicDataSource();
basicDataSource.setUrl(dbUrl.toString());
basicDataSource.setUsername(username);
basicDataSource.setPassword(password);
return basicDataSource;
}
I'm using node.js and was trying to run my knex migrations for my Heroku app. I tried appending ?sslmode=require to the connection URL but it didn't work. I added ?ssl=true instead and now it works perfectly.
Here's an example Heroku PostgreSQL connection URL that works:
postgres://user:password#ec2-12-34-56-78.compute-99.amazonaws.com:port/databasename?ssl=true
Add or edit the following line in your postgresql.conf file :
listen_addresses = '*'
Add the following line as the first line of pg_hba.conf. It allows access to all databases for all users with an encrypted password:
TYPE DATABASE USER CIDR-ADDRESS METHOD
host all all 0.0.0.0/0 md5
Restart postgresql service:
net stop postgresql-9.0 & net start postgresql-9.0
(version should be based on your installation) -- On windows (run cmd as an administrator).
sudo service start postgresql -- On linux (or according to your linux distribution.)
const pool = new Pool({
connectionString: process.env.DATABASE_URL,
ssl: {
rejectUnauthorized: false
}
});
