MySQL open files limit

Upgrade Migration – Kaltura CE 4.0 to 5.0

I was migrating Kaltura from CE 4.0 to 5.0 but following MySQL error made me unhappy 🙁

One or more prerequisites required to install Kaltura failed:
Please set ‘open_files_limit >= 20000’ in my.cnf and restart MySQL (current value is 1024)

# ulimit -a | grep “open files”

# ulimit -n (get and set user limit on resources)

mysql> show variables like ‘open_file%’;

The open file limit is an important variable for performance when MySQL server has to open several files at once. If open_files_limit is set to a lower value then MySQL query might fail causing other problems or might take too long to execute.

Then I have changed /etc/my.cnf

I had put the open_files_limit line in the [mysqld_safe] section, but it seems that section is no longer used. So, I have Moved all config options to [mysqld]

You could try using –skip-broken to work around the problem
You could try running: package-cleanup –problems
package-cleanup –dupes
rpm -Va –nofiles –nodigest
The program package-cleanup is found in the yum-utils package.

…….

# rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
# yum –enablerepo=webtatic install php php-mysql

OR

# yum –enablerepo=webtatic update php php-mysql
# php -v

Get Remote Host Client IP Behind Load Balancers (ELB)


Hits: 20314  

I was working on “Private AWS Cloudfront Distribution” for AWS Elastic Load Balancer (ELB), allowing our application servers private access to our AWS cloudfront.

But PHP Server Environment Variable $_SERVER[“REMOTE_ADDR”] is displaying suspicious results, it really tedious to get remote host client IP behind ELB 🙁

Now we have 2 options…

1. mod_rpaf and Amazon ELB
http://tech.superhappykittymeow.com/?p=281
http://giantdorks.org/alain/easily-get-the-correct-client-ip-with-mod_rpaf/

if ($_SERVER[“HTTP_X_FORWARDED_FOR”]) {
$realclientip = $_SERVER[“HTTP_X_FORWARDED_FOR”];
} else {
$realclientip = $_SERVER[“REMOTE_ADDR”];
}

2. %{X-Forwarded-For}i from Apache Log (Time Consuming)
http://blog.kenweiner.com/2009/09/amazon-elb-capturing-client-ip-address.html
https://forums.aws.amazon.com/message.jspa?messageID=216977

You Apache log format would then look something like this:
LogFormat “\”%{X-Forwarded-For}i\” %l %u %t \”%r\” %>s %b \”%{Referer}i\” \”%{User-agent}i\”” combined-elb
CustomLog log/acces_log combined-elb

Apache Module mod_remoteip

PHP: $_SERVER[“HTTP_X_FORWARDED_FOR”]
PHP: $_SERVER[“HTTP_X_CLUSTER_CLIENT_IP”]

$_SERVER[‘REMOTE_ADDR’]; Apache Enviromental Variable is not working on your server 🙂
