In order to connect via the mongo shell, the docs says to download a *.tgz file.
So I downloaded the shell file mongodb-osx-x86_64-3.2.9, unzipped it, clicked on the /bin/mongo icon in the mac finder, which opened a shell but with error:
~$/Users/abcdef/Downloads/mongodb-osx-x86_64-3.2.9/bin/mongo ; exit;
MongoDB shell version: 3.2.9

$meteor mongo reports MongoDB shell version 3.2.6
$mongo --version reports MongoDB shell version 3.0.12
The reason for this question is to run MongoDB 3.2.6 with TLS/SSL support. Any idea? Thanks

After the recursive chmod suggested in the comments which fixed on problem. Now the second problem which is, I am not able to log in to The Atlas cluster.
/$mongo "mongodb://cluster0-shard...shard-0" --ssl --username *** --password ***
Error parsing command line: unknown option ssl
But when I use the file downloaded from mongo as stated at the start of this post. it opens a mongo shell fine. How to login to my Atlas cluster?
Do I type the command suggested by mongo Atlas on the bash terminal or the mongo shell?
Run this command and then try to run mongod which will start mongodb server
sudo chown -R $USER /data/db
Once mongo server is up then connect to shell using mongo.
And if you want the directory to be owned by particular user or group you can do this using
sudo chown -R username:groupname /data/db
for e.g sudo chown -R mongod:mongod /data/db
the specified user should be present other wise it will give you below error
chown: invalid user: 'mongodb:mongodb'
error:NETWORK [ReplicaSetMonitor-TaskExecutor-0] Successfully connected to cluster
The problem is your mongo client version.
You have to updade to Mongo 3.4 with suport SSL

Having trouble installing postgres 10 on my Mac, version 10.12.5.
I've tried installing 2 ways:
(1) Downloading Postgres.app
(2) `brew install postgresql`
and tried to manually run a bunch of variations of these commands for initdb:
$ initdb /Applications/Postgres.app/Contents/Versions/latest/bin/ver-10
$ initdb /usr/local/var/postgres -E utf8
All yield the same error FATAL: could not create semaphores: Invalid argument.
Full trace:
The files belonging to this database system will be owned by user "foo".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

I'm not sure what FATAL: could not create semaphores: Invalid argument means. I've seen a lot of other answers related to insufficient space, but not this one.
Thanks in advance!
I had to remove Postgres which I install via Brew, and then I reinstalled Postgres.app, and then restarted my computer, and then opening the app and clicking 'initialize' fixed it.
My application uses the blazer gem for visualizing DB queries.
During the setup I've encountered the following error:
FATAL: no pg_hba.conf entry for host "111.22.33.44", user "blazer", database "my_db", SSL off
My application is hosted on EngineYard and uses PostgreSQL.
How can I find and modify the pg_hba.conf on EngineYard?
upd
I do have SSH access to EngineYard cloud.
Instance: General Purpose (M3) Large.
OS: EngineYard's Gentoo.
You can try the following steps. I've assumed that your DB name is my_db.
Connect to the instance via SSH (the link can be found on the EngineYard environment page)
Connect to the
database as superuser psql -U postgres -h localhost -d
my_db. If you don't have the password, check your database secrets here /data/my_db/current/config/database.yml
After connecting to DB identify location of hba file by typing SHOW
hba_file;
Quit psql by typing \q
Use previously identified path to open the hba_file file and add the missing user. E.g via vim sudo vim /db/postgresql/9.5/data/pg_hba.conf. Note the sudo command
The use should be added under # IPv4 postgres
user for 10.x with md5:
Connect to the database again
Reload the configuration via select pg_reload_conf(); command
After all steps are performed, Blazer queries should be accessible.
I just updated my mac OS X to Yosemite, version 10.10.4, and postgresql to: psql (PostgreSQL) 9.4.4.
After running rake db:migrate on my Rails 4.2.1 application, my terminal session is responding with:
rake aborted!
PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
Simply entering psql in my terminal session also appears a bit off:
$ psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
After printing out the logs from, cat /usr/local/var/postgres/server.log, I read:
DETAIL: The data directory was initialized by PostgreSQL version 9.3, which is not compatible with this version 9.4.4.
LOG: skipping missing configuration file "/usr/local/var/postgres/postgresql.auto.conf"
FATAL: database files are incompatible with server
I found this answer on SO, but I a hesitant to just start creating a bunch of directories unless that's really what I am suppose to do. I also found an older answer but am not too sure if it's the one to follow.
This SO answer suggests that I remove a, /usr/local/var/postgres/postmaster.pid, but I do not have one, I have a, /usr/local/var/postgres/postmaster.opts -- should I remove the postmaster.opts?
There appears to be lots of advice, but I am not too sure what to follow. Can someone offer some advice in getting my postgresql database running on my rails application?
You could upgrade the database by following an official guide:
brew switch postgres 9.3 # presuming you already installed 9.4.4
pg_dumpall > outputfile
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
mv /usr/local/var/postgres /usr/local/var/postgres.old
brew switch postgres 9.4.4
initdb -D /usr/local/var/postgres
psql -d postgres -f outputfile
PostgreSQL upgrade
Basically, I had to drop and recreate my own database and re-seed it with remote staging data. What I did not understand is that the problem with updating a database is that the data itself also needs to be 'updated' in a way. The data was compatible with a different version
I would like to use the same MongoDB database I use on windows 7 as I do on Ubuntu.
On Ubuntu, I went into the file: /etc/mongodb.conf
and changed dbpath=/var/lib/mongodb to dbpath=/media/meaniostack/OS/data/db which is the database on the windows partition.
When I tried starting up mongod & mongo, I got the following error:
MongoDB shell version: 2.6.7
connecting to: test
2015-01-30T14:19:11.027-0500 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-01-30T14:19:11.028-0500 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed
However, when I go back to dbpath=/var/lib/mongodb, it works like normal. Keep in mind, that I have mounted media/meaniostack/OS
How do I make this work, and is it possible? Does mongodb, use a different type of storage compared to the one in Ubuntu?
After a bit of messing around I found the solution to be:
Alter permissions to the folders that the database is in.
Change the mongodb.conf path variable
Use mongod --dbpath /media/meaniostack/OS/data/db instead of: service mongod start
Hope this helped anyone with a similar issue.
The error in its entirety reads:
psql: could not connect to server: No such file or directory. Is the
server running locally and accepting connections on Unix domain socket
"/tmp/.s.PGSQL.5432"?
This is my second time setting up Postgresql via Homebrew on my Mac, and I have no clue what is going on. Previously, it had been working. At some point, I must've entered a command that messed things up. I'm not sure. Now, whenever I enter a SQL command from the command line, I receive the above message. I've run a command to check whether the server is running, and it apparently is not. If I attempt to start the server using
$ postgres -D /usr/local/pgsql/data
I receive the following error:
postgres cannot access the server configuration file
"/usr/local/pgsql/data/postgresql.conf": No such file or directory
I've uninstalled and reinstalled Postgresql via Homebrew, but the problem persists. I'm completely at a loss as to how to get this working. Any help would be appreciated.
your data directory is most likely wrong.
issue a "sudo find / -name "postgresql.conf" " on your terminal to see where your postgres file resides. Then, do an ls in the data directory. Use that in the -D option when starting postgres.
