Enable SWAP in Openvz VPS

Swap memory is now available within openvz containers with RHEL6 series stable kernel. It is a good turn point of openvz containers. The latest kernels starting from 042stab035.1 now support swap within the containers. It is an entirely different memory management model for Openvz containers and this new swap model is called Vswap. Now you only need to take care of the following two parameters for configuring the memory physpages and swappages . These are the primary parameters . All others now become secondary

physpages : This parameter limits the physical memory (RAM) available to processes inside a container. The barrier is ignored, and the limit sets the limit.
swappages : This parameter limits the amount of swap space which can be used for processes inside a container. The barrier is ignored, and the limit sets the limit.

How to set SWAP on Openvz Vps ?
You can use the vzctl command interface to set the swap for the vps.

For example I need to set the swap to 1024 MB for a container 1000 , see below,

# vzctl set 1000 --swappages 0:1024M --save

See the swap result below,

[root@node ~]#  vzctl exec 1000 free -m
             total       used       free     shared    buffers     cached
Mem:          4096       1814       2281          0          0       1814
-/+ buffers/cache:          0       4096
Swap:         1024          2       1021

When physpages limit is reached, memory pages belonging to the container are pushed out to so called virtual swap (vswap). The difference between normal swap and vswap is that with vswap no actual disk I/O usually occurs. Instead, a container is artificially slowed down, to emulate the effect of the real swapping.

How to install php-imap in directadmin

This installation documentation is based on RHEL or Centos based server. If you have debian or BSD , you need to install the proper c-client binary.

# yum install libc-client libc-client-devel krb5-devel krb5-libs

Now edit the file /usr/local/directadmin/custombuild/configure/ap2/configure.php5 and add the following two lines.

--with-imap  \
--with-imap-ssl

Now build the php using the following

# ./build php 5

After the compilation check the phpimap support using a phpinfo page

# php -m | grep imap

It is the easy way to install php-imap in directadmin server

PS: If you  have 64 bit server make sure to enable a soft link as follows

# # ln -s /usr/lib64/libc-client.a /usr/lib/libc-client.a

WHM Nameserver IPs Showing Wrong Info

Sometimes you can see wrong information regarding WHM/cPanel nameserver info. You can see it from Main >> DNS Functions >> Nameserver IPs . To fix this issue you need to edit two files /etc/nameserverips and /var/cpanel/nameserverips.yaml

1) Edit the file /etc/nameserverips .See an example below,

# cat /etc/nameserverips
192.168.1.100=ns1.yourdomain.com
192.168.1.101=ns2.yourdomain.com

2) Edit the file /var/cpanel/nameserverips.yaml , See an example below,

root@it [~]# cat /var/cpanel/nameserverips.yaml
--- 
ns1.yourdomain.com: 
  "192.168.1.100": 1
  count: '1'
  zones: yourdomain.com
ns2.yourdomain.com:
