I have setup LiteSpeed and I have got a problem with php and mysql.
It seems php can't connect to mysql. At every script which use mysql(like phpbb3, phpbb2 etc) I getting errors
SQL ERROR [ mysql4 ] Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) [2002]
phpBB : Critical Error
Could not connect to the database
I have a database server – mysql.xx.com which is the main MySQL server in H-Sphere.
I've created a database from mysqladmin interface.
I can use the database without a problem but when I’m trying to access the database from another server that I’ve just installed, the PHP application says that it can not connect to the database.
Another thing is that if I move the php app with the same configuration file under a shared account under another H-Sphere server, it's working perfectly.
I’ve read the H-Sphere documentation about an option to enable remote access to the mysql server which I can’t find anymore under our H-Sphere 2.5 Patch 8.
I’ve done a lot of searching to see how can I make that PHP application to connect to mysql.xx.com but it seems that although I’ve run the command grant all …. Command for that database, it still doesn’t work.
One final thing – from that new server if I run "mysql –h mysql.xx.com –u user –p" I can connect to the database and do a use database, show tables etc.
From iptables on mysql.xx.com I see that it accepts connections from outside.
This issue of not getting that PHP application to connect to mysql.xx.com can be related to the fact that H-Sphere is using the server or what should I try further?
I'm trying to diagnose where my problem is coming from.
I have a site hosted with Integra Telecom. The site is connecting remotely to a MySQL database hosted on Media Temple.
My problem is that the site's connection to the MySQL database seems to be fluctuating throughout the day. Sometimes the site is up, sometimes it's down.
When it was down, I got the error: "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)"
So is the problem with Integra Telecom or is my problem with Media Temple?
Currently mysql.max_persistent and mysql.max_links are set to -1 which means unlimited
to optimize mysql, should i keep this unlimited or is it good to limit this? If i have to limit it, what is the best value that I can put there?
I have win2003 server and running plesk 8.4, there is a website on it and it gives me error with mysql max_connection even I set the limit 1 million or 10000 no matters.
View 3 Replies View RelatedWe have a front end server for the website Zymic.com (a free web hosting community), a mysql server and a main server for hosted websites. The problem lies between establishing a connection from the Zymic.com server to the database server - to sum it up, the connection just "hangs". We have never had this problem before, never edited anything which would cause a problem, its completely spontaneous.
My administrator has spent endless hours trying to debug the problem, here are some notes he gave me:
1. Ping to the mysql machine works fine.
2. Telnet to port 3306 of the mysql machine works great too – meaning NOT a network issue.
3. Strace on the connection shows it hangs when it calls the server and waits endlessly for response.
4. The mysql machine listens to the IP and port 3306 and connects great to the hosting server via SSH.
5. It's NOT a max connection issue but something to do with the mysql socket itself.
Here is a test from another site on the server to the mysql server:

Code:
<?php
mysql_connect('75.126.138.74', 'wkscript', 'PASSWORD') or die(mysql_error());
mysql_select_db('domains_data') or die('SELECT ERROR : ' . mysql_error());
?>

What is the standard number on maximum mysql connection on most shared host providers and which one give the highest number.
View 11 Replies View RelatedI bought a VPS to run a part of a application I have and it needs to connect to my database in cpanel. I have set everything up properly and allowed the remote server to connect to my server, I updated the DB connect file with the correct mysql server username and password. But when I try and run the script I get this error.

I'm not 100% sure what to do. I don't understand why it wouldn't work because it works perfectly on the main server with my scripts. But I get that error message on the remote server.
I have developed a desktop system that uses MySQL data.
I want to use a host to access the data but my current provider only allows access to MySQL data via a web server.
Can anyone suggest a host that would provide direct connection to a MySQL database?
how to allow user to remote mysql connection from his localhost ( in linux server with WHM )
my user wants to connect to the mysql from his localhost
some vBulletin customers facing to that error message, with session table with attachment only. Other just work fine. It's not because of server load. The load is just around 0 - 0.1
I have increased wait_timeout to 200 and max_allowed_packet to 64MB. Each attachment file in those vBulletin is just around 1-3MB.
Is there any idea why and how to fix?
A have set up a cpanel with remote mysql server.
My demo config:
cpanel:
centos VPS with cpanel WHM (demo)
mysql:
debian VPS
the configuration is OK, it works.
We have got 200 customers, and we will to change to cpanel.
The MYSQL server is on a solaris zone. It is possible to make the remote connecting with it. I will import the 200 users MYSQL databases to cpanel, with privileges (user settings). The mail/web dir a will import manuali to cpanel server(copy-paste-setuser:group).
I just got a new server and discoverd very strange problem. It happends 2-3 times every hour. When I try to access some webpage which connects to MySQL, I get page header and then page hangs for some 1 minute. After some 1 minute everything is back to normal. I can open several windows with different websites hosted on my server and the same problem is in all windows. At the same time I can access al websites without MySQL connections.
I have Fedora Core5
MySQL version 5.0.27
I have 2 identical Fedora8 boxes with Apache 2.2.8, MySQL 5.0.45 and PhP 5.2.4. I use one as the Web+DB server (say box A), and the other (box B) just as the Web server connecting to the DB server on box A. I use this 2 machine configuration to test a LAMP based-Web application. I have a client program on other machines that can emulate a massive web workload to these 2 servers; it can emulate hundreds to thousands of users using the application simultaneously.
Before running the test, the connection to the DB server from both boxes seem fine. Using the mysql client program on either box A or B trying to connect to the DB, the connection goes through instantly. In the /etc/my.cnf file, I have max_connections=4096 and max_user_connections=4096. Note that the web app uses one single db user to connect to the db. To allow remote connection, I inserted one record into the user table of the mysql db whose the host field's value is '%' (allow connection from all remote hosts).
After running the test (which I found out that many requests sent to box B failed), mysql client program on box A is still able to connect to the db instantly; but the one on box B has a problem: it takes extremely long (5 - 10 minutes or even more) to establish the connection, it doesn't time out, just takes that long. I believe that's the cause for the failure of requests to box B.
The main function of my dedicated server is the vBulletin forum that we run.
Ever since I had bastille firewall installed and configured on my server we have been getting regular vBulletin errors.
Everything runs pretty smoothly most of the time, we can carry lots of connections without any issues, server has plenty of free RAM and CPU is never overloaded even during peak hours. I have been told bastille firewall (iptables) is configured correctly, all ports that need to be open are open.
But about twice per day we have a MySQL "disconnect" that lasts about 30-60 seconds per incident. For example we will start getting the following message via e-mail, and it will amount to 20-30 e-mails like this during the 30-60 second incident. After that, the e-mails and problems will go away, until next time.
vBulletin Database Error!

The server is running CentOS 4.6, PHP 4.4.7, MySQL 5.0.45. The vBulletin software has been patched to the latest version. The vBulletin people are not sure why this could be happening.
Well we never believed that the firewall was causing the issue BUT it only started happening on the day the new firewall was installed. So we tried stopping the firewall for a full week and the MySQL database errors stopped happening, completely. So I'm convinced the problem is the firewall blocking MySQL connections but I can't figure out why?
There are no entries in the MySQL .err logs pertaining to this. Can't figure this out, any help or ideas is appreciated since the people who installed the firewall are not sure either.
I freshly installed Plesk 12.0 on Ubuntu 14.04. Everything works accept the MySQL database creation.
When I try to create one, i get this error :
error: the test connection to the database server has failed because of network problems: connection refused...
I have ftp server (pure-ftp). with firewall.
i allowed 20 and 21 port in "CSF" firewall
now when i or our client connect to the server connection done.
and the they fire dir or ls command they will receive error
"425 Could not open data connection to port 2535: Connection timed out"
what is the problem.i have already allowed passive port 2500:3500 then why i received this types of error

IOwait is less than 10% most of the times.
So litespeed told me to go with a 2 CPU core license.
1. So since i going with 2 CPU core license. It will only make 2 cores user litespeed for PHP out of 8 cores? what other cores gonna do? only static content? Or other cores gonna use Apache for php? can you plz explain.
2. Do we have to configure cache like mod_cache, mod_disk_cache, and mod_mem_cache etc with litespeed too? Or it has its own methods of caching?
3. Should use their PHP LiteSpeed SAPI over normal PHP?
Is there any compatibility problems with scripts like Vbulletin, jamroom?
Anyone happen to know the difference between the two and whether or not I'll notice the difference between them?
For example, many, many, many, many moons ago, in a far away land, there used to be a difference between Windows and Linux for perl scripts. In fact, if you couldn't re-write half the script, some of them just didn't work right on a windows host.
Are there any differences like that between lightspeed and apache, or is it all pretty much the same and doesn't really matter?
I'm now running litespeed server to power sites on a VPS. Currently, a site is working without https access normally. However, when you access the site via HTTPS (SSL), I recieve ioncube is not loaded. Comparing the phpinfo, it appears that the https is loading the old configuration of phpinfo, what's worse, is that it's loading PHP 4. Both however, load the same PHP configuration file.
View 1 Replies View Relatedwhen I type "top" into ssh I see 3 proccesses of lshttpd, 2 are running by nobody, 1 by root., lsws is installed as nobody:nobody. Also, I see 2 lsphp5 processes, by nobody both. I have 4 virtual hosts configured. Are those proccesses normal, I think there should be only 1 proccess lshttpd and lsphp5.
Can you check if you are running litespeed how many proccesses of lshttpd you have?
My litespeed is not using httpd.conf
I have a site hosted at steadfast.net - I like it very much especially the speed is Great and the prices are Good. However i am having a lot of connection errors and MySQL Problems.
Is there any other shared hosting that uses Litespeed ? with Good Prices and Good Reviews ?
i am interested to install Litespeed on my vps (with cpanel)
it is good?
I no longer have the funds for a LSWS lic, so I need to move to Apache. I run CPanel and need help in configuring Apache to be able to take 120 requests/sec and no crap out.
I've never worked with Apache since been using LiteSpeed for over 2 years, so I need some advice on how to set it up, compile, configure, ect...
I started a thread last night to get some opinions as I am trying to find a new host & now am coming up with another question... Apache vs Litespeed. A cpanel is important to me, which I am not sure is possible with Litespeed & a highly rated company that offers LS, Medialayer, doesn't offer phone support which is mandatory to me. Can't find many companies that offer Litespeed & everything else that I need.
So as not to repeat, please see the tread I started last night to get the gist of my needs. I also another opinion over there on Liquidweb. See:

I have litespeed enterprise.
Will mod Security work with it? I doubt it, because it says Apache. But just wondering.
Dos anyone know of anything else, besides the security section on litespeed?
Any packages like mod security, that work with Ubuntu and LiteSpeed?
Due to heavy load, our web server get crashed. We have plan to use LiteSpeed web server, is anybody used these server. I like to know performance of these.
View 11 Replies View RelatedI tried searching for it on google but couldn't find any server company offering VPS using Litespeed instead of Apache. Yes, I know that Apache could be optimized, but would like to try a VPS or dedicated server with Litespeed, just for testing and learning to use and troubleshoot Litespeed. Does anybody here know of a supplier? I would need less than 10 gigs, 250+ Ram as well as cPanel.
View 13 Replies View RelatedI installed lsws without apache conf file(httpd.conf). Then I created a new virtual host in "suEXEC" Template. I added a new user via SSH and made home dir for him and chowned his home dir + all his files to hisusername:hisusername. His home dir(/home/user/) is chmoded to 755 and his /public_html to 711. It worked fine but after that I installed phpbb3 forum and when I tried to chmod config.php to 600 I got an error on the forum:
Fatal error: require() [function.require]: Failed opening required './config.php' (include_path='.:/usr/local/lib/php') in /home/username/public_html/common.php on line 127
When I was using lsws with apache conf file and I had configured suEXEC + suPHP for apache I was able to chmod config file to 600 and it worked fine. I have no idea what could be the problem now.
It works fine when I chmod config.php to 755 but for security reasons I would need a way to configure it to 600.
