Solution:

First need to remove the particular domain name from

/etc/remotedomains

and add the domain name in

/etc/localdomains

That is all fixed my issue

can not use due to limits - cpanel package

For cpanel new package create you will throw out some error like
"can not use due to limits"

This is mainly when you are trying to add some unlimited package.

So please note that for unlimited package add do not use "unlimited" instead of that use "99999" like that. This fixed my issue.

Softaculous error (Solved) - vtiger

memcache installation

Installing Memcache in Cpanel server/ Linux Servers

Memcache is a memory caching system to get the memory for where you required more and it used your system memory to a better way

First we need to install the libeven. This API will helps to execute a callback functon when a specific event accure. This is useful when there is a timeout is occured for a particular process.

Installtion is covered in three steps

Step 1: Libevent
#cd usr/src/
#wget http://monkey.org/~provos/libevent-2.0.12-stable.tar.gz
#tar -xvf libevent-2.0.12-stable.tar.gz
#cd libevent-2.0.12-stable
#./configure
#make
#make install
: You have to note down the libeven installation location from the above installation. In most cases this will be on /usr/local/lib
Then you need to update the libeven shared libraries for that we want to edit the /etc/ld.so.conf.d
#vi /etc/ld.so.conf.d/libevent.conf --> /usr/local/lib
write and quit from this file
and execute the command
#ldconfig
# ldconfig -v |grep libevent
ibevent_pthreads-2.0.so.5 -> libevent_pthreads.so
libevent_openssl-2.0.so.5 -> libevent_openssl.so
libevent_core-2.0.so.5 -> libevent_core.so
libevent_extra-2.0.so.5 -> libevent_extra.so
libevent-2.0.so.5 -> libevent.so

Step 2 : memcache

Now we can install memcache
#cd /usr/src
#wget http://memcached.googlecode.com/files/memcached-1.4.6.tar.gz
#tar -xvf memcached-1.4.6.tar.gz
#cd memcached-1.4.6
#./configure
#make
#make install
You can confirm the memcache is stalled on your server using the command
#which memcached

Step3: Memcache for php module

#cd /usr/src
#wget http://pecl.php.net/get/memcache-2.2.6.tgz
#tar -xvf memcache-2.2.6.tgz
#cd memcache-2.2.6
#phpize
#./configure
#make
#make install
Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/
Now we need to edit the php.ini for the memcache exention. Please confirm the above locaton is your default extension extension_dir. For my this is the same location in my php.ini
So I have added the line [ extension = "memcache.so" ] without the [ ] symbols.
write and quite the php.ini file and restarted the apache server
#/scripts/restartsrv_httpd
Now we can confirm memcache php module has been installed or now using the command
#php -m | grep memcache
and aso touch a info.php file and check the memcache module is listed or now

Thats it you have finished ...
