I did all this: http://dev.mysql.com/doc/refman/5.6/en/resetting-permissions.html
The mysqld is running in the command prompt and I can connect with the new password. But, the database is gone.
Luckily i found my root password again, and tried to login (with workbench) when the service is running normally with the "networkservice" user. Now I wonder why I can't change the password for the networkservice instance. It seems that the database is hooked up to that windows user.
I installed the mysql with the installation wizard.I have tried a lot of things, I cant reset the password for the MySQL 5.6 service running on Windows 8. I have tried running the reset as administrator in cmd, and it starts an instance in the command prompt, I can connect with the new password, but it's not the same as the MySql56 service...
I have tried to run start paramters in the service options, but it seems that windows are ignoring it when starting the services.
Any suggestions why?
I needed to change the defaults-file destination to the hidden folder: C:\ProgramData\MySQL\MySQL Server 5.6\my.ini

i am facing an issue while using the mac. I need to use that PowerShell command on my mac to run application as domain user
runas /netonly /user:user_name "C:\Users\fwa\AppData\Local\Programs\Azure Data Studio\azuredatastudio.exe"
I have tried
sudo -u user_name /Applications/AzureDataStudio.app
it asks password for local user. but in my case user is on External domain
To run Azure Data Studio (ADS) on your mac and login to SQL Server using Windows authentication instead of a username/password, you use the kinit command. I've had best luck using the kinit command through the built-in command window in ADS (you'll be prompted to do so if/when your login fails). Note that your computer needs network access to a kerberos server.
There's some further information about setting this up HERE and HERE.
I have just install Postgres 9.3 on Windows 7. The installation completed successfully. It has never asked me to provide the password for postgres user.
The service postgresql-x64-9.3 is up and running. However, I cannot connect: I do not not know the password. I've found the following answer, but it did not help:
similar question on Ubuntu
[LINUX]
might work for windows too
After installing postgres follow following steps in order to setup password for default system account of Linux execute following in terminal:
user:~$ sudo -i -u postgres
postgres#user:~$ psql
after executing above two commands you will get into postgres shell
Execute this query in postgres shell:
postgres=# ALTER USER postgres PASSWORD 'mynewpassword';
your new password is 'mynewpassword' without quotes and now you can connect with external GUI tools like DBeaver
WARNING: trust means exactly that. Anyone who can connect to the PostgreSQL server can control it. If you set trust mode that allows superusers like user postgres (or all users) to connect, they get total control of your PostgreSQL and can probably run shell commands too. You should usually only use it to change the password then restore the configuration back to the auth mode you were using before.
If you used an unattended installer script, the password will be in the script or associated config file.
Otherwise, treat it the same as if you lost/forgot the password rather than never knowing it:
Edit pg_hba.conf, setting the auth mode to trust instead of the default md5
In the Services control panel restart the PostgreSQL service
Connect with psql or PgAdmin or whatever
ALTER USER postgres PASSWORD 'mynewpassword';
Edit pg_hba.conf again and set the auth mode back to md5
Restart PostgreSQL again
pg_hba.conf is in your data directory. By default it'll be %PROGRAMFILES%\PostgreSQL\9.3\data.
To edit it you'll have to use the security tab to give yourself read/write permissions (via a UAC prompt). This might require you to set yourself as the owner of the file.
On unix systems it's more secure to prepend a
local all all peer
line to pg_hba.conf and then sudo -u postgres psql (assuming your PostgreSQL server runs as user postgres) to get an interactive psql session without using a password. That way you don't have to use trust.
On initialisation you can access the DB as:
Username: postgres
Password: postgres
By default user postgres does not have a password
Start psql and create a password:
sudo -u postgres psql
\password postgres - It will ask you enter a password for user postgres
Through trial and error I found that the password for Postgre SQL 10 for the username postgres is "admin". I kept typing in different password until I reached that password. I am using pgAdmin 4 to test out my SQL Statements, POSTGRE SQL 10 is the first server connection set up using localhost.
It seems there was no default password, but psql wouldn't accept a lack of a password (fe_sendauth: no password supplied). To get around this, I opened pgAdmin, then in the left sidebar:
Servers
Login/Group Roles
Right click postgres and click Properties,
Go to Definition tab
Set the password in the Password field
After saving, psql accepted that password. There may have been a switch I could have supplied to have it accept a lack of a password (--no-password?), but the user should probably have a password anyways, so this seemed reasonable.
go to control >> computer management >> Locaol users and group >> users >>
right click on openpgsvc >> set password.
after that now you can access with this password on openpgsvc
The simplest solution I've found is just to install PgAdmin and connect to the local server with the current Windows credentials (username + password). Then you can change the password to the postgres user.
step1: Go to control panel
Step2: Click on Administrative Tools
Step3: Click on Computer Management
Step4: There under "Local Users and Groups" Double click on user
Step:5: then right click on postgres and you can set password

Win7. Postgres 9.3.
Every time I type "postgres" in cmd I get this error.
Created a new account without any admin rights and with "Log on as" rights and with correct directory access rights to postgres/data, then I set this account as the "Log on as" in the services menu, but I still get the same error.
update2017: I never found a solution to this.
For windows do this:
Start cmd.exe (administrator as you are)
Add postgres user:
net user postgres your_password /add
Start a cmd.exe using your new postgres account:
runas /user:postgres cmd.exe
You can validate you are login correctly using" whoami
Run postgres normally.
It is not clear from your question whether you are trying to start the Postgres service or "manually" start Postgres without having a Windows service registered.
Since 9.x Postgres does not require it's own Windows user account to run the service. It defaults to use the built-in "Network" account.
To start the Postgres service (if it has been correctly installed), simply use use
net start postgresql-9.3
(the actual name might be different)
If you did not register a Windows service you should start Postgres through pg_ctl.exe not through postgres.exe. pg_ctl.exe will drop any administrative privileges from the process when starting the server.
To start Postgres manually from the commandline use:
pg_ctl -w -D c:\Path\To\The\DataDirectory
assuming that the access rights to the data directory are setup correctly so that the current user has full access to the directory.
If you want to install/create the Windows service manually, you can also do this through the pg_ctl program:
pg_ctl register -N "postgresql-9.3" -D c:\Path\To\The\DataDirectory
Again the access rights to the data directory must be setup correctly.
I got my new lion machine. Ran the PostgreSQL installer from the PostgreSQL site for Mac and i have no multiple apps installed. One of them is "pgAdmin III.app". When I open it there is already one server connection available. localhost:5432
Whenever I try to connect to the server with a doubleclick the programm asks me for a password. I have no idea what to enter. It's not my admin password, it's not "postgres", it's not "localhost", it's not empty.
I just can't seem to connect to the server. Even when I check the properties of the localhost server the password field seems empty. However I'm not allowed to leave the password field empty.
Any idea what to do? I really need to setup postgres?
On my Mac OSX Lion, PostgreSQL configuration files are stored under /Library/PostgreSQL/9.0/data/
Haven't tried it on OSX, but on Ubuntu you can login as the system user 'postgres' to the default database 'postgres' without a password with
su postgres -c psql
You can then (re)set the password of the database superuser 'postgres'.
You can also edit the configuration file pg_hba.conf (don't know where it is located on a default OSX installation, on Ubuntu it is /etc/postgresql/8.4/main/pg_hba.conf) and grant access to the default database without authentication
# TYPE DATABASE USER CIDR-ADDRESS METHOD
host postgres postgres 127.0.0.1/32 trust
After editing pg_hba.conf you must reload the configuration with
pg_ctlcluster 8.4 main reload
You can then connect with pgAdmin and (re)set the password, but don't forget to change the authentication method back to md5 again...
here's a better answer (works in OSX HighSierra): the account used is the one you're logged onto OSX with, therefore, the password is your password!
A similar question has been asked a short time ago. The steps described there should be appropriate for Lion also.
Postgresql: password authentication failed for user "postgres"
I had installed IBM DB2 Content Manager 8.4.1 months ago and now I wanted to access it to continue some more work.
But when I try to log in using System Administration Client, it tells me the password is expired. The error is:
DGL0394A: Error in ::DriverManager.getConnection;[jcc][t4][2012][11248][3.50.152]
Connection authorization failure occurred. Reason: Password expired.
ERRORCODE=-4214,SQLSTATE=28000 (STATE) : ;
[SERVER = icmnsldb, USERID = icmadmin, SQL RC = -4214, SQL STATE = 28000]
I've tried looking thru the config files, using the java update command line.. and I can't find a way to change or reset the password. I can't use System Administration Client to change the passwords, since it won't log me in to begin with. Any other method I can use to reset/change the password for a DB2 CM user?
DB2 uses the operating system to authenticate users, so you need to use the OS tools to reset the icmadmin user's password. Your post is tagged as Windows, so look for the icmadmin user in either the local machine or in the domain if your server belongs to a domain.
Just use the Client for Windows on a desktop machine and not the eClient to login. It will directly notify about a expired password and you can set the new password immediately.
I faced the same issue. I logged in as root and chaged the password for db2 user by passwd . and changed in the WAS console. It worked.
In Windows, click on start > Control Panel > User Accounts > User Accounts > Manage User Accounts.
Here, select the DB2 username and click on Reset Password.
If you are on Docker, you need to perform a docker exec into the DB2 container (Linux) and then change the password for the local user that you are trying to log in to DB2 with. In my case, the name of the user was "myuser". I changed the password by executing
passwd myuser
Note that you are root by default when you exec into the container. Else use
docker exec -u root <containerName> /bin/sh
