Liblua error: relocation R_X86_64_32 against `luaO_nilobject_’

The full error will be like as below:

/usr/bin/ld: /usr/local/lib/liblua.a(lapi.o): relocation R_X86_64_32 against `luaO_nilobject_’ can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/liblua.a: could not read symbols: Bad value

I got the above error in between easyapache. It’s pretty sure lua is present in server but something went unoticed or bad while its installation. The missing part was nothing but I compiled 32 bit lua in 64 bit server, so the above error was showing mismatch class error for liblua.

I tried to recompile lua as follows:

Download lua source archive from their official site

# cd /usr/src
# curl -R -O
# tar zxf lua-5.2.3.tar.gz

Now you need to make sure that you will compile this time for 64 bit class.

For compilation in 64 bit arch server, you should make the following changes in lua source file before proceeding with installation.

# cd lua-5.2.3
# vi src/Makefile





Save and exit from file.

Now do the installlation.

# make linux test

# make

# make install

you are done 🙂 now the job left is to finish the easyapache process.

Error while loading shared libraries:

I got this liblua error while apache,php recompilation.

At first I tried to find the dependencies of lua

# ldd `which lua` => (0x00007fff1dd7d000) => not found => /lib64/ (0x0000003b68800000) => /lib64/ (0x0000003b68400000) => /lib64/ (0x0000003b68000000) => /lib64/ (0x0000003b67800000) => /lib64/ (0x0000003b67400000) => /lib64/ (0x0000003b6a400000)
/lib64/ (0x0000003b67000000)

Then I tried to search for liblua in “/” using find command.

# find / -iname liblua*

The made a symlink like as follows:

# ln -s /opt/lua/lib/ /opt/lua/lib/

# ll /opt/lua/lib/
lrwxrwxrwx 1 root root 13 Aug 18 11:08 /opt/lua/lib/ ->*

Now do recompile again and finish the process successfully 🙂

In case if lua is completely missing, you can install using yum or do manual compilation.

# yum install lua lua-devel

for manual compilation, download lua source from and install it.

Red5 Media Server: Installation And Configuration (Centos/Fedora/RHEL)

Red5 Media Server delivers a powerful video streaming and multi-user solution to the ©Adobe ©Flash Player and other exciting client technologies. It works based on Java and some of the most powerful open source frameworks, Red5 stands as a solid solution for business of all sizes including the enterprise.

Streaming Video (FLV, F4V, MP4, 3GP)
Streaming Audio (MP3, F4A, M4A, AAC)
Recording Client Streams (FLV and AVC+AAC in FLV container)
Shared Objects
Live Stream Publishing
Protocols: RTMP, RTMPT, RTMPS, and RTMPE

Lets look at the installation and configuration part:

1) First you need to install Java since red5 is a Java server. Use yum to install it.
If you are not sure about the version or proper package to be installed from yum repo, then search it.

# yum search java | grep openjdk
java-1.6.0-openjdk-devel.i686 : OpenJDK Development Environment
java-1.6.0-openjdk.i686 : OpenJDK Runtime Environment
java-1.6.0-openjdk-demo.i686 : OpenJDK Demos
java-1.6.0-openjdk-javadoc.i686 : OpenJDK API Documentation
java-1.6.0-openjdk-plugin.i686 : OpenJDK Web Browser Plugin
java-1.6.0-openjdk-src.i686 : OpenJDK Source Bundle

I am gonna install java-1.6.0-openjdk.i686 and java-1.6.0-openjdk-devel.i686 from it.

#yum install java-1.6.0-openjdk.i686 java-1.6.0-openjdk-devel.i686

2) Now we need to install SVN to retrieve new red5 release from Google SVN repositary.

#yum install subversion

3) Install Ant and Ivy in support for Java
Apache Ant is a Java library and command-line tool that help building software. Ivy is a dependency manager, it manages and controls the JAR files that your project depends on. If you don’t have the JARs, it works by default by taking from the Maven repository directly, which can make project setup a lot easier.

Download binary form of apache-ant(NOT THE SOURCE CODE)

# cd /usr/src
# wget (:::You can download latest from
# tar xvf apache-ant-1.9.4-bin.tar.gz
# mv apache-ant-1.9.4 /usr/local/ant

Make a symlink for ant binary to /usr/bin for the shortcut and easiness to access it.

#ln -s /usr/local/ant/bin/ant /usr/bin/ant

Download Ivy from Apache repositary

# cd /usr/src
# svn co ivy
# cd ivy
# ant jar

Wait for few minutes for process to be over. Once it is success, you will see the Build Complete Message.

# cp build/artifact/jars/ivy.jar /usr/local/ant/lib/   (::: Since you are in path cd /usr/src/ivy)

4) Export Variables for Ant and Java:

Java and Ant is in place now, now we need to make sure we set Environment Variables. They are global variables with paths specified to different binaries or applications. ANT and JAVA will need those.

# export ANT_HOME=/usr/local/ant
# export JAVA_HOME=/usr/lib/jvm/java
# export PATH=$PATH:/usr/local/ant/bin

5) Actual Installation of Red5 Server begins

We need to fetch the Red5 source from Google SVN repositary.

# cd /usr/src
# svn co red5
# mv red5 /usr/local/
# cd /usr/local/red5

(This is the folder where all the source files reside. From here on, we prepare and build the red5 source)

# ant prepare
# ant dist

Wait for sometime for the process to be completed. Once it is over, you will see message “BUILD SUCCESSFUL” at the end.

Copy the conf directory from the dist folder to the current directory and test the red5 installation.

# cp -r dist/conf .             (::: Since you are in path /usr/local/red5)
# ./

You will see a lot of process going on in screen and it starts the Red5 server.

Check whether the ports 5080 and 1935 are listening or not in a second/duplicate shell

# netstat -plan | grep -E ‘:5080|:1935’
tcp 0 0 :::1935 :::* LISTEN 1309/java
tcp 0 0 :::5080 :::* LISTEN 1309/java

Test if server works by checking the url http://yourserverIP:5080

Make sure you enable incoming connections to ports 5080 and 1935 in server.

# iptables -A INPUT -p tcp -m tcp –dport 5080 -j ACCEPT
# iptables -A INPUT -p tcp -m tcp –dport 1935 -j ACCEPT
[[[NOTE::: The red5 runs only as long as you keep the terminal window open since you started running the script in it. It will stop running if you close shell which is not an efficient way to run red5 server like that way. You need to make sure it can run by its own initiative]]]

You may need to set the script starts running while server boots up, do the following for it.

#vi /root/

Enter the following commands in it.

cd /usr/local/red5/

#chmod +x /root/

Set this script in file /etc/rc.local so that it will start running along with start up scripts in server.
So the rc.local would like as shown below:
# cat /etc/rc.local
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don’t
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
sh /root/ &

((In above the “&” at the tail end of command “sh /root/” is run the process in background))
6) Setup an Init script for Red5 server

# vi /etc/init.d/red5

Then enter the following script in it.

# For RedHat and cousins:
# chkconfig: 2345 85 85
# description: Red5 flash streaming server
# processname: red5
# Source function library
. /etc/rc.d/init.d/functions
[ -r /etc/sysconfig/red5 ] && . /etc/sysconfig/red5
case “$1” in
echo -n $”Starting $PROG: ”
$DAEMON >/dev/null 2>/dev/null &
if [ $RETVAL -eq 0 ]; then
echo $! > $PIDFILE
touch /var/lock/subsys/$PROG
[ $RETVAL -eq 0 ] && success $”$PROG startup” || failure $”$PROG startup”
echo -n $”Shutting down $PROG: ”
killproc -p $PIDFILE
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$PROG
$0 stop
$0 start
status $PROG -p $PIDFILE
echo $”Usage: $0 {start|stop|restart|status}”
exit $RETVAL

Assign execute permission to red5 script

# chmod +x /etc/init.d/red5

Now start the service

# service red5 start OR /etc/init.d/red5 start

Set Red5 to start along with start up programs while server booting

# chkconfig –add red5
# chkconfig red5 on

To install some RED5 demos

# cd /usr/local/red5/webapps/root
# svn checkout

To install some demo apps


Then install Admin demo and Ofla Demo from the page

Access Demo Apps in Red5


Test ofla demo


Then correct rtmp url like rtmp://yourserverip/oflaDemo and hit connect. Choose any of the demos from the list and play it.


Test Publisher to live stream, record videos etc.

You will see three tabs on left side server, video, audio

In server tab, change the location to rtmp://yourserverip/oflaDemo and on the video tab, select your cam from Device scroll list.


All the above would work fine if you follow the instructions correctly 🙂


Some error you may encounter while the installation time

1) During the step ant prepare and ant dist , you may sometime reach at the following error.

[ivy:resolve] ::::::::::::::::::::::::::::::::::::::::::::::
[ivy:resolve] :: org.apache.commons#commons-modeler;2.0.1: not found
[ivy:resolve] :: red5#xmlrpc;2.0.1: not found
[ivy:resolve] ::::::::::::::::::::::::::::::::::::::::::::::

For this change the following path in file ivysettings.xml in directory /usr/local/red5/

replace the
<artifact pattern=”[organisation]/[artifact]-[revision].[ext]”/>
<artifact pattern=”[artifact]/[artifact]/[revision]/[artifact]-[revision].[ext]”/>

CHECK_NRPE: Error – Could not complete SSL handshake

If you find this error in nagios for a particular server, this means nothing but the nrpe check from nagios server cannot able to complete the service check to client server.

You can check this through command line itself, run the following in nagios server.

# /usr/local/nagios/libexec/check_nrpe -H hostnameORclientserverIP -c check_load
CHECK_NRPE: Error – Could not complete SSL handshake.

You may need to cover different scenarios for this to troubleshoot.

1) Check if the particular check is available in client server (For example, check_load, 3ware_check, mail_count etc)

2) Check if xinetd or nrpe stopped running,otherwise try to restart it.

# /etc/init.d/xinetd restart
# /etc/init.d/nrpe restart

3) Make sure you allowed the nagios IP in /etc/xinetd.d/nrpe if nrpe is running under xinetd,like as getting in netstat result.

# netstat -plan | grep :5666
tcp 0 0* LISTEN 25022/xinetd

Check the parameter “only_from” in this file whether allowed nagios IP there.

Then restart xinetd

# /etc/init.d/xinetd restart


Make sure you allowed the nagios IP in /etc/nagios/nrpe.cfg if nrpe is not running under xinetd and as nrpe user itself, like as getting in netstat result.

# netstat -plan | grep :5666
tcp 0 0* LISTEN 248184/nrpe

Make changes to value of parameter “allowed_hosts” in /etc/nagios/nrpe.cfg to as shown below


Then restart nrpe

# /etc/init.d/nrpe restart

4) Try to whitelist nagios server IP in firewall.


nload monitoring tool

The tool nload makes it simple for us to check the incoming/outcoming traffic rate in server, it’s pretty nice and handy tool. This is very useful to check traffic stat when a server is under ddos attack.

How to install it?

Download nload source from
# tar xvf nload-0.7.4.tar.gz
# cd nload-0.7.4
# ./configure
# make
# make install

Or you can install it using rpm, download it from here

Basic Commands
$ nload
$ nload eth0
$ nload em0 em2



Once we confirm whether it is inbound or outbound, we can use further methods like iftop, tcpdump, apache status through WHM or httpd fullstatus via shell.

Manually rearrange domains due to disk space warnings

If you see home partition space warnings and you want to move high sized account from it to second home partition, you can either do it from WHM Home » Account Functions » Rearrange an Account. Doing it from WHM interface is good for accounts that have less size. Say if the account has size over 10GB or 15GB or so, go for manual move.

But please note that when moving it manually, you should make the changes in following areas. Otherwise you gonna jeopardize the account.

Suppose if you are moving a high sized account “test” from /home to  /home2

– First step move it from /home to /home2

#mv -f /home/test /home2/

Now the rest of changes in all necessary config files.

#replace /home/ /home2/ — /var/cpanel/userdata/test/*
#replace /home/ /home2/ — /etc/proftpd/test
#replace /home/test /home2/test — /etc/passwd
#replace /home/test /home2/test — /home2/test/etc/*/passwd


#/etc/init.d/httpd restart

#/etc/init.d/pure-ftpd restart

You are done 🙂

cloudlinux: PHP selector NOT working or BROKEN

It was truly devastating and I was dismayed when I noticed the PHP selector in server got broken or stopped working since the last easy-apache. Tones of tickets were popped in when clients lost their custom php versions and its custom settings

I tried to select the php version 5.4 for the domain and set post_max_size and upload_max_filesize to 32MB each







And I checked by putting a phpinfo page in the domain, sadly the changes I made in php selector settings had no effect








Following is the solution that I could finally find out to fix it … tadaa 🙂

PHP configured as suphp in server
# /usr/local/cpanel/bin/rebuild_phpconf –current
Available handlers: suphp dso fcgi cgi none
PHP4 SAPI: none
PHP5 SAPI: suphp
SUEXEC: enabled
RUID2: not installed

We must check if is present in /opt/suphp/sbin/suphp since it is suphp compiled with lve. In this case Cagefs and PHPSelector can’t work properly. You can check this by searching file /opt/suphp/sbin/suphp . Use strings command to read it since it is a binary file.

# strings /opt/suphp/sbin/suphp | grep lve

Output should be as…

# strings /opt/suphp/sbin/suphp |grep lve
Could not resolve path “

If it is not present, then you need to run:

# /usr/sbin/

Then force update cagefsctl to update alt_php.ini of all individual users in server.

# cagefsctl –force-update

Now see my changes 🙂









This should solve your issue
