Install suphp on directadmin using custombuild

While managing DirectAdmin server  you might sometime want to change the php handler to suphp instead of default mod_php. Because suphp provides better protection to server than mod_php because it runs the php scripts under the user account instead of default user apache. DirectAdmin custombuild provides a very easy way to do it.

cd /usr/local/directadmin/custombuild/
./build set php5_cgi yes
./build set php5_cli no
./build set ioncube yes
./build all d
./build rewrite_confs

Note: If you just want to upgrade PHP
./build set php5_ver 5.5
./build update
./build php n

service httpd restart

Note: If you just want to build ioncube
cd /usr/local/directadmin/custombuild
./build update
./build ioncube
./build php-ini
service httpd restart

Now after suphp is installed on the server. You will need to fix phpMyAdmin, Roundcube and squirrelmail

./build roundcube
./build squirrelmail
./build phpmyadmin

No you can fix the permissions of all the files and folders of the users.

for i in `/bin/ls /usr/local/directadmin/data/users/` ; do chown -R $i.$i /home/$i/domains/* ; echo $i ;done
for i in `/bin/ls /usr/local/directadmin/data/users/` ; do find /home/$i/domains/ -type f -exec chmod 644 {} \; ; echo $i ;done
for i in `/bin/ls /usr/local/directadmin/data/users/` ; do find /home/$i/domains/ -type d -exec chmod 755 {} \; ; echo $i ;done

OpenVZ quota recalculate

vzctl stop 1100

vzquota drop 1100

vzctl start 1100

While starting VE with VEID 200 quota will be recalculated


In our base CentOS 6.3 image it uses a few endpoints in the EPEL repos that are set by default that use SSL 3.0. Due to this you will receive the error noted below when attempting to use yum update from the instance. This article will show you how to remedy that while we work on deploying an updated CentOS 6.x image.


Loaded plugins: fastestmirror, security
Determining fastest mirrors
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again.


We will update this knowledge base article once we have an updated and fixed CentOS 6.x image.

The CentOS 5.8 and CentOS 7 images available to use don’t have this issue.

Walkthrough Steps

Running this command will update the repo to use HTTP rather than HTTPS:

sudo sed -i "s/mirrorlist=https/mirrorlist=http/" /etc/yum.repos.d/epel.repo

You should then be able to update with this command:
yum -y update

How can I determine what is taking up so much space?

1. Use linux command
du -hscx *

2. Write shell script

if [ "$1" == "-b" ] ;then
    export units=(b K M G T P)
    export duargs="-xbs"
    export minsize=${2:-$((256*1024**2))}
    export units=(K M G T P)
    export duargs="-xks"
    export minsize=${2:-$((256*1024))}

humansize() {
    local _c=$1 _i=0
    while [ ${#_c} -gt 3 ] ;do
    _c=$(( ( $1*1000 ) >> ( 10*_i ) ))
    printf ${2+-v} $2 "%.2f%s" ${_c:0:${#_c}-3}.${_c:${#_c}-3} ${units[_i]}

export device=$(stat -c %d "${1:-.}")

rdu() {
    local _dir="$1" _spc="$2" _crt _siz _str
    while read _siz _crt;do
        if [ $_siz -gt $minsize ];then
        humansize $_siz _str
        printf "%s%12s%14s_%s\n" "$_spc" "$_str" \\ "${_crt##*/}"
        [ -d "$_crt" ] &&
