If you receive the above error while compiling any package , it means  that the /tmp partition is mounted in “noexec” mode and that you do not have permissions to execute anything under /tmp partition.

Execute the “mount” command and you will see something like:

root@server [~]# mount
/dev/sdax on /tmp type ext3 (rw,noexec,nosuid)

To mount the /tmp partition in rw mode, execute:

root@server [~]# mount -o remount rw /tmp

Now, you can execute the “pecl” command to install the package you like. Once done, you can remount /tmp with noexec mode again:

root@server [~]# mount -o remount rw,noexec,nosuid /tmp

If you are facing issues with keyboard mapping in ubuntu which is the most common error currently you can use the below solution,

Find your start up script

find / -name xstartup

in file xstartup

You have to add the line export XKL_XMODMAP_DISABLE=1 before /etc/X11/Xsession or gnome-session (in case you use GNOME)

export XKL_XMODMAP_DISABLE=1

restart your vnc and all is fixed

now all is done and  ffmpeg is installed .

Make sure you add  extension=ffmpeg.so in php.ini

Check the mount permissions on your /tmp directory in your server.

You will  need to remount /tmp as executable.

# mount | grep /tmp
/dev/sda1 on /tmp type ext3 (rw)
/tmp on /var/tmp type none (rw,noexec,nosuid,bind)

$ mount -o remount,exec,suid /tmp

do your compiling, then

# mount -o remount,noexec,nosuid /tmp

Done now you can compile  

Check the below module on your hardware node

# modprobe ppp_async
# modprobe ppp_deflate

The below command will show the modules if installed.

# lsmod | grep ppp
ppp_deflate            39168  0
zlib_deflate           52760  1 ppp_deflate
ppp_async              45184  0
crc_ccitt               6337  1 ppp_async
ppp_generic            20165  6 ppp_deflate,ppp_async
slhc                   30561  1 ppp_generic

Now, set ppp module  on your vps from the hardware node.

# vzctl set VEID –devices c:108:0:rw –save
# vzctl exec VEID mknod /dev/ppp c 108 0
# vzctl exec VEID chmod 600 /dev/ppp

Now, restart your  VPS using below command

# vzctl restart VEID

Now

vzctl enter VEID

Check the module in vps using below command

# /usr/sbin/pppd
