I am learning MySQL and stumbled upon a problem after installation of MySQL. I switched to sql mode and from there I tried to connect to root#localhost but after I inputted the password, it says there is no such Host. I tried other host names, but the same results show where it says
ERROR: 2005: No such host is known 'hostname'
I even tried to make a simple table, but when I enter it, I get the error that says ERROR: Not Connected, which was expected. How exactly do I get through this, I am a bit lost despite having everything installed.
I use commands such as:
mysql-sql> \connect 127.0.01;
From there enter a password and no success.
Check the list of hosts names inside this file
C:\Windows\System32\drivers\etc\hosts
If you can't see this 127.0.0.1 localhost add it on new line on bottom.
If it's there but the line start with # remove this symbol.
You can try "127.0.01" instead localhost.
I think, Felipe meant \connect root#127.0.0.1 instead of 127.0.01

I just created my first SQL database using MAMP. (It is simple- just a list of pets.) I would like to load it into R. Here is what I wrote:
install.packages("dbConnect")
library(dbConnect)
mypets=dbConnect(MySQL(),user="root",
host="localhost1234/DatabaseGrace")
This error is returned:
Error in mysqlNewConnection(drv, ...) :
RS-DBI driver: (Failed to connect to database: Error: Unknown MySQL server host 'localhost1234/DatabaseGrace' (2))
Any idea what this means or how I can solve it?
Thank you #duffymo and #Lorenz.
Summary:
The database is stored on my computer, so host did need to be localhost as you suggested.
Here is what ended up working.
install.packages("RMySQL")
install.packages("dbConnect")
library(dbConnect)
dbGrace=dbConnect(MySQL(),user="root",
host="localhost",
dbname="DatabaseGrace",
password="root",
unix.sock="/Applications/MAMP/tmp/mysql/mysql.sock")
Thanks, all!
I think the host name should be "localhost", without the 1234.
If you intended that to mean the port, I'd check to make sure that MySQL is indeed listening on that port. The default value is 3306; the admin would have to make a conscious decision to change that.
The usual notation is "localhost:3306" in Java. If you must include the port number, try separating it from the host name with a colon.
Can you connect to MySQL using the admin shell?
Have you GRANTed permission to localhost to connect to database named DatabaseGrace? If not, MySQL won't allow you to connect.
http://dev.mysql.com/doc/refman/5.1/en/grant.html
localhost suggests to me that the database is running on your local machine. Is that true? If not, localhost isn't the right host name. It might also mean that you have a firewall between your machine and the database which prevents you from connecting.
I get a lot of mileage out of cutting & pasting any errors I get into Google to see if anyone else has ever experienced my problem. Here's the first hit.
The host is the computer name. So put simply localhost.
Select the correct database in a second step.
this works for me with XAMPP on MAC:
library(RMySQL)
con=dbConnect(MySQL(),
host='localhost',
unix.sock='/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock',
user='root',
password='...'
)
df=dbGetQuery(con,'SHOW DATABASES')
print(df)
I keep getting the error 1045(28000) when trying the mysql -u user -p command. The same password works in the MySQL Command Line Client and the server is running according to Workbench and Notifier. Not sure if this is related, but the only odd thing is that Notifier shows that I have two things running, both named "MySQL56_1" and when I try to stop the one where I don't have the option to "Configure Instance" or open the "SQL Editor", I get the error saying that it was "not found in the Windows Services".
EDIT: still have not solved this, all of the commands mentioned here yield error 1045 with the variations of mentioning either 'user'#'localhost' or 'ODBC'#'localhost'
The error 1045(28000) denoted for Access Denied to the user..
You are using different connection parameters in sql editor and cmd..
Cross check your username, password, socket file path, hostname and reconnect via cmd.
Thanks
Ok, if anyone is interested, here what worked for me. In Workbench, on the bottom left hand corner, there will be all these "schemas" listed, click on any one (they all show the same parameters in my case at least) and, using all the relevant parameters specified under Information>Session, play around with the commands listed in this chapter . Basically what user Aman Aggarwal was talking about, just took me a while to understand how this cross checking is done exactly.
I'm trying to try my hand out with Kamailio and Freeswitch.
I'm following the article listed here:
http://nil.uniza.sk/sip/kamailio-33-and-freeswitch-122-interconnection-voicemail-and-conference-services-debian-squeeze-60-64bit-tutorial
After adding the #!define statements, the article says to try to restart kamailio. When I do that, it fails with the error:
driver error: Access denied for user 'kamailio'#'localhost' (using password: YES)
I'm not sure which configuration file would contain the name of the default user that's used to log in to mysql. I did make the recommended changes to kamctlrc where you define the dbhost, dbname and the read write user etc. But none of those settings made reference to this user "kamailio". Not sure where to check.
Thanks.
Upon closer examination, I found that not only do I have an /etc/kamailio/kamailio.cfg file but /etc/kamailio/kamailio-advanced.cfg.
I made the changes the article suggested for kamailio.cfg in kamailio-advanced.cfg instead... and all is well. I was able to start the service again. I'm not sure if the database will work but at least I'm one step closer and now authentication is working.
I has had two days searching and exploring solutions regarding the error 2003.
Can't connect to mysql server on 'Server name'.
The firewall is off and I had added the port 3306, the one that mysql uses.
Any recommendation?
Please refer this FAQ which describes how to solve this issue: http://faq.webyog.com/content/23/15/en/error-no-2003-can_t-connect.html
Error No. 2003: Can't connect to MySQL server on 'localhost' (or some other host)
simply means that connection is not possible for one of the following (or similar) reasons:
There is no MySQL server running at the specified host
Connection to the MySQL server is not allowed using TCP-IP. Check the 'skip-networking' setting in the MySQL configuration file (my.ini on Windows, my.cnf on Unix/Linux). It shall be commented out like '#skip-networking'. If it is not commented out, then do it and restart the MySQL server for the change to take effect. SQLyog needs to connect using TCP-IP.
Some networking issue prevents connection. It could be a network malconfiguration or a firewall issue.
When trying to connect to a MySQL server at an ISP this error message often indicates that direct connection to MySQL has been blocked. You must then use HTTP-tunneling or SSH-tunneling to connect.
It worked for me.controll pannel->administrative tools->services->mysql and start mysql.Some times simple solution saves lot of time.
normally means that there is no MySQL server running on the system .
check your server running
this could be due to firewalls of the system try below command and check
service iptables stop
i have the same issue but i fix it.
my hostname is DEBIAN, i just modify the file my.cnf ( for mysql) and set bindaddress : 0.0.0.0
this option say to mysql to listen all interfaces. restart your server and finish
if your question refer to can't connect to mysql on hosting (cpanel), i also had same problem.
I also turn off firewall, but it doesn't solve my problem.
Rather than using server name or domain name on Mysql Host Address, i using ip address given by hosting provider.
And it works.
Going to services and starting MYSQL service doesn't work for me.
Finally, I hit the following commands inside the MYSQL command-line client:
ALTER USER 'username'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
There is a high chance that you are making one of the two mistakes.
First :
You are inputting the wrong password. check your password or change it with
this command
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'very_strong_password';
In place of 'very_strong_password' give a strong password of your choice.
Second:
You are using '#' in the password which can be confused with the other with #localhost.
The SQL Sever might not be installed.
Please refer this to install:
MySQL
The solution worked for me
Go to services and start MySql services
window: press the start button and search services. Then star MySql services
I was using mysql 5.6.11,it usually turned down and show me this:
2005 - Unknown MySQL server host 'localhost'(11001).
Currently my resolution is to turn off the network,than it return to normal.I had searched a lot,but no answer is revalent to it.So,does anyone knows the reason?
ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)
modify list of host names for your system:
C:\Windows\System32\drivers\etc\hosts
Make sure that you have the following entry:
127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem
(you may need to change modify permission to modify this file)
This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.
I have passed through that error today and did everything described above but didn't work for me. So I decided to view the core problem and logged onto the MySQL root folder in Windows 7 and did this solution:
Go to folder:
C:\AppServ\MySQL
Right click and Run as Administrator these files:
mysql_servicefix.bat
mysql_serviceinstall.bat
mysql_servicestart.bat
Then close the entire explorer window and reopen it or clear cache then login to phpMyAdmin again.
The case is like :
mysql connects will localhost when network is not up.
mysql cannot connect when network is up.
You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):
Disconnect the network.
Stop mysql service (if windows, try from services.msc window)
Connect to network.
Try to start the mysql and see if it starts correctly.
Check for system logs anyways to be sure that there is no error in starting mysql service.
If all goes well try connecting.
If fails, try to do a telnet localhost 3306 and see what output it shows.
Try changing the port on which mysql is hosted, default 3306, you can change to some other port which is ununsed.
This should ideally resolve the issue you are facing.
Follow these steps to fix this error
Use \connect root#127.0.0.1 instead of \connect root#localhost
if it doesn't work then go to C:\Windows\System32\drivers\etc\hosts and check the IP address attached to host name.
use that IP, so it will be.
\connect root#the_ip_address_you_found
