Can't Connect To MySQL Server On 'localhost' (10055)
Jun 24, 2009
Do you guys know anything about this?
My server works perfectly with INSERT, UPDATE, DELETE for mysql.
but after like 12 hours later, my application crashes and I get this
"Can't connect to MySQL server on 'localhost' (10055)" and I would have to restart my applications and everything will be working perfectly.
Do you guys have any idea why this happen?
I do have a lot of connections coming in and out of my server. Would that mean anything?
I am stuck in re-installing mysql server..... Everything I have removed even mysql service give reboot the machine but still not able to complete the installation.
At the end I receive error " Can't connect to Mysql server with LocalHost (10061)
By the way if port 3306 is not enabled in firewall can this issue be occurred because of this?
I am using localhost as mysql server name on my config file. then, when I enter [url], the address will automatically change to[url]that obviously getting error. when I change the mysql server name from localhost to the server public IP, everything seems ok.
My sql is 4.1.x with php 4.4.7, is that any way I may use localhost instead of IP?
After the upgrade of our Plesk installation from 9.5x to 11.5.30Everything works ok (sites,sites with databases, Plesk etc)but when I go to Home>Tools & Settings> Backup Manager.I see errors on every daily backup I have on schedule:
The backup Plesk_Daily_Full_Backup_1407060112.tar has completed with warnings. (View the details) Close this message

I have a few users that have a hosting account with me and are trying to connect to their own MySQL servers elsewhere. Both said that they are able to connect to the MySQL server with other hosting accounts but not the ones hosted with me. I asked if they had setup permissions to allow remote connections from my server and they confirmed that they did.
What am I missing? Do I need to configure my firewall somehow? I figured the connection is just using port 80 since it's from an PHP script right?

I've been using Dreamhost for years and they're very good, but their MySql databases are quite slow. Then I moved to ServInt with a VPS, and my MySql is on localhost instead of on a different server. WOW! It's so fast!
However, now I'm trying to find a shared hosting package that has fast MySQL service.
I'm not sure if the requirement is that it's on localhost but it sure doesn't hurt.
Is there anyone who is familiar of a good solid shared hosting package with fast MySQL service?
I have windows server 2012 and Plesk v12.0.18 #30 - I noticed speed problem.
When I try to connect to mySQL with:
$conn = new mysqli('localhost', 'joomla_***', '*****', 'joomla_test');
Connection takes 1 second!!!When I try to connect with '127.0.0.1' instead of 'localhost' connection takes 0,009 seconds.
1. I tried solution to add line '127.0.0.1 localhost' to c:windowssystem32driversetshosts - but no luck.
2. I tried to edit C:Program Files (x86)ParallelsPleskMySQLDatamy.ini - adding lines bind-address=127.0.0.1 skip-name-resolve then restarted mySql but 1 second lag time on connection was still there.
3. I even tried to disable IPv6 but still no luck
I guess all users windows windows server 2012 has the same problem??!?!...
I started getting small periods of intermittent connection errors about once every hour, lasting for about 1 to 5 minutes each time: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'
I enabled the error log and did some other monitoring and established 2 things: - the server doesn't crash/restart, it keeps running throughout the errors - the errors do not match the load on the website, as sometimes when 500 users are online there are no errors, but when 300 are online they may by prolific
I checked many forums and then made 5 changes: - changed the directory containing the mysql.sock file so only file owners or superusers can delete files from it - I changed the default socket file setting in both my.cnf and php.ini - I read about SELinux causing such a problem, so I disabled SELinux completely, rebooted the server and double-checked that it is indeed disabled. - I changed the maximum amount of open files allowed by the operating system from 1024 to 30000.
Despite all these changes, I still get the errors. I then read that there is a workaround by using TCP/IP instead of the sock file. I tried that, but I still get the error intermittently in the form of: Can't connect to MySQL server on 127.0.0.1
MySQL server 4.1.20, PHP 4.3.9, client API 4.1.20, CentOS 4.3, Intel P4 2.8GHz 1GB RAM
I am using cPanel 11 (stable release) on a CentOS 5 server and would like to make it so that a certain database can only be connected to from the cPanel user that it is under (ie. user1_db can only be connected to from the user "user1" on the same server).
I saw following error in some of my site in my server.
Coppermine critical error: Unable to connect to database !
MySQL said: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)
or following error :
Invalid mysql server connection
Please help me how can I resolve this error !

I got this weird problem with my VPS which has MySQL 4.1.22 running on it. Everything works fine for sometime and then out of a sudden, it stop recognizing the mysql users and refused to allow my PHP scripts to access the database.
It seems that I needed to restart mySQL server to resolve the issue. Then out of the blues, the same problem occurs.
I am running Cpanel on a VPS and there isn't any overloading as the database access is pretty light on my 512mb VPS.
I contacted my web host about the issue and it seems like all they do is to restart the mySQL. This cannot be a solution as it happens at least once or twice a day depending on how soon I could catch the problem.
All the time this problem occurs, the MYSQL Server is still active and working. I can even access it through PHPMyAdmin but not through the scripts.
I just added an hourly crontab so as to restart the MySQL server as a stop gap.
I have a set up where server 1 holds a mysql DB and a virtual host. server 2 holds many virtual hosts in apache (16) connecting to this DB.
The virtual hosts all hold the same script, but the single VH on server 1 receives about the same amount of visits as all the VHs of server 2.
server 1 is very busy at times, like 100% CPU and a load around 10 for long period of times. server 2 is not very busy, around 30% CPU usage and 0.6 CPU load.
Yet, users on server 2 experience *much slower* response times than the ones on server 1.
The obvious reason could be the network between the two, but I'm not convinced (6 seconds for a query run from server 2 when it brings back 1 row and takes 0.01 second from server 1).
Why so many sleeping processes from server 2, and none or almost none from server 1 ? Is it normal that every query from server 2 is open on a different port ? Should they be grouped by virtual host, or is there one different port for each script running concurrently?
What could be a reason for server 2 having problems to open connections on server 1, and how to solve it?
Right now I'm about to deport more users from server 1 to new virtual hosts on server 2, hoping it will lower the load on the first machine and overall accelerate the response times. I just thought I'd post here first because this all seems very weird to me and i thought someone with an external look might tell me what I'm doing wrong. And also if network would be the problem maybe that's not the clever thing to do to make more users remote.
i then used a MD5 generator to input the hash in the password field of the roundcube user in mysql, with no luck...I even tried to delete roundcube user from mysql, then remove psa-roundcube, then go through the plesk update manager and install roundcube again, did not change nothing, it didn't even create the roundcube user.
Is there anyway i can reinstall roundcube from scratch?PPP 11.5 up to date on ubuntu 12.04
