I am doing a mongodump, and want to store it in a specific location. So, from reading online, I can do this using the following command:
sudo mongodump -d mydbs -u user -p password -o /myfolder/mongoBackups
I am using an EC2 instance, and when I run this command from my centos home folder, this is the output I get from mongodump:
2017-01-07T16:01:42.053+0000 writing mydbs.users to
2017-01-07T16:01:42.055+0000 done dumping mydbs.users (2 documents)
However, when I cannot find the folder myfolder/mongoBackups anywhere in the specific home/centos location where I run it. Any idea why?
It's not within home/centos
It's in /myfolder/mongoBackups
Specifying an output directory of /myfolder/mongoBackups is basically putting it in a folder called myfolder on the root of the hard drive.
If you truly want the folder to be within home/centos try
sudo mongodump -d mydbs -u user -p password -o /home/centos/myfolder/mongoBackups

Problem
when in tried run sql file in psql shell...
give "No such file or directory" error!
$ ls
config.sql config.yaml
$ sudo -i -u postgres psql
postgres=# \i config.sql
config.sql: No such file or directory
thanks for your reply!
Quick solution:
-i => goes to user's home directory!
as result ./config.sql address is incorrect!
just use
$ psql -U <user_name>
postgres=# \i config.sql
man sudo tells you:
-i, --login
Run the shell specified by the target user's password database entry as a login shell. This means that login-specific
resource files such as .profile, .bash_profile or .login will be read by the shell. If a command is specified, it is passed
to the shell for execution via the shell's -c option.
In particular, that will set your current working directory to the home directory of user postgres.
If you want to avoid that, don't use '-i'.
Im writing a shell to automate a process this shell will be run as root or as another user but not as the postgres user (meaning the user will just run the script)
What i did as a postgres user while testing was
touch /var/lib/postgresql/10/main/recovery.conf
sudo nano recovery.conf (wrote some content )
ctrl +O
However whenever I try to do this by using the following lines in my shell as as another user (including root)
sudo -H -u postgres bash -c "touch /var/lib/postgresql/10/main/recovery.conf"
The file is created as postgres user which is what i intended, and then i run
sudo -H -u postgres bash -c echo "content" > /var/lib/postgresql/10/main/recovery.conf
and get a
-bash: /var/lib/postgresql/10/main/recovery.conf: Permission denied
How come I can create the file but not put content on it?
I already tried giving 775 and 777 permisions using chmod
chmod 775 recovery.conf
as the psotgres user and i get
-rwxrwxr-x 1 postgres postgres 133 May 11 22:11 recovery.conf
to this file as a postgres user and still the error persists so im confused about whats going on
At the second line where you try to put the "echo" command, please use:
/var/lib/postgresql/10/main/recovery.conf
With a / at the beginning
I need to export a database I created to get the code for creating the database and inserting rows.
I understand there is a method of using pg_dump, but all the walkthroughs of using it I can find seem to be on Linux.
Can anyone tell me how to do this on Windows?
You have to execute pg_dump located in the bin folder of your PostgreSQL install.
Ex : C:\Program Files\PostgreSQL\9.4\bin.
The command is pg_dump -U *username* -p *port* -d *database* -W -f *filename*
All the parameters are case sensitive ! (Check your username !)
U is for specifying the user that will connect to the DB.
If you don't specify it, pg_dump will use the login you're logged on with.
p for the port. (Default is 5432)
d for the database name
W to force pg_dump to ask for password
f the name of the file where the export should be stored. If you don't specify this, the dump will be displayed in the console.
Example :
pg_dump -U postgres -p 5432 -d postgres -W -f c:\vm\dump.sql
You may need special permissions to export the file to some folders.
(i.e. : C:\program files\ requires administrative rights for writing.)
I was just following this tutorial HERE, its about, pgrouting, When I run the following command:
psql -U user -d postgres -f ~/Desktop/pgrouting-workshop/data/sampledata_routing.sql
I get an error saying the following:
/var/lib/postgresql/Desktop/pgrouting-workshop/data/sampledata_routing.sql: No such file or directory
On my desktop I do have a folder pgrouting-workshop, which does contain the folder data and the sql dump file.
So why am I getting this error?
Because your Desktop isn't in the postgres user's home directory, located at /var/lib/postgresql, but is instead located at /home/myusername/Desktop?
Presumably the psql command you're running is under a sudo -u postgres -i shell, so ~/ means the postgres user's home directory.
Use ~myusername/Desktop/blahblah. Note that the postgres user may not have permission to access it; you can chmod go+x ~ ~/Desktop (run as your user, not postgres) to change that.
For a while i have my db running on a command window because im not figuring out how to run it as a windows service.
Since i have the zip file version downloaded. how can i register the pg_ctl command as a windows service?
By the way, im using the following line to start the server:
"D:/Program Files/PostgreSQL/9.0.4/bin/pg_ctl.exe" -D "D:/Program Files/PostgreSQL/9.0.4/db_data" -l logfile start
Thanks in advance.
Use the register parameter for the pg_ctl program.
The data directory should not be stored in Program Files, the location of %ProgramData% is e.g. a good choice.
pg_ctl.exe register -N PostgreSQL -U some_windows_username -P windows_password -D "%ProgramData%/db_data" ...
In newer versions of Postgres, a separate Windows account is no longer necessary, so the following is also sufficient
pg_ctl.exe register -N PostgreSQL -D "%ProgramData%/db_data" ...
Details are in the manual: http://www.postgresql.org/docs/current/static/app-pg-ctl.html
You need to make sure the directory D:/Program Files/PostgreSQL/9.0.4/db_data has the correct privileges for the windows user you specify with the -U flag.
Btw: it is a bad idea to store program data in Program Files. You should move the data directory somewhere outside of Program Files because Program Files is usually highly restricted for regular users - with a very good reason.
Just run 'Command Prompt' as windows administrator and run the below command:
pg_ctl.exe register -N PostgreSQL -D "D:/Program Files/PostgreSQL/9.0.4/db_data"
You don't need to specify a User and Password, as previous answers have suggested.
