== Software ==

=== mcrypt ===

Use one of the following:

<pre>yum search mcrypt
yum install libmcrypt-devel
yum install libmcrypt.x86_64
yum install php-mcrypt.x86_64</pre>

You may need to enable the EPEL repository first, which can be done using [[CentOS#Additional_Resources.2FRepository | this]].

=== suphp on CentOS 6 ===

<pre>wget http://www.suphp.org/download/suphp-0.7.1.tar.gz ; tar -zxf suphp-0.7.1.tar.gz
cd suphp-0.7.1

yum install gcc gcc-c++ httpd-devel
yum install make

./configure --with-apr=/usr/bin/apr-1-config --with-apache-user=apache --prefix=/usr
make
make install</pre>

That should have installed it correctly now you need to edit the conf files.

vim /etc/httpd/conf/httpd.conf #(modifications)

=== MySQL Support in PHP5 ===

To get MySQL support in PHP, install the php-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for applications. You can search for available PHP5 modules like this:

<pre>yum search php</pre>

Pick the ones you need and install them like this:

<pre>yum install php-mysql php-gd php-imap php-ldap php-mbstring php-odbc php-pear php-xml php-xmlrpc
*Then restart Apache2*
/etc/init.d/httpd restart</pre>

[http://www.php.net/manual/en/mysqli.installation.php mysqli]

Alternatively you can use:

<pre>yum install php-soap.x86_64</pre>

=== [http://thebitstream.co.uk/helpful-stuff/install-mssql-on-centos-6 Install MSSQL PHP Extension on CentOS 6] ===

=== phpMyAdmin ===

phpMyAdmin is a web interface through which you can manage your MySQL databases. First [http://wiki.centos.org/AdditionalResources/Repositories/RPMForge enable the RPMforge repository] on your CentOS system as phpMyAdmin is not available in the official CentOS 6.1 repositories:

Import the RPMforge GPG key:

<pre>rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt</pre>

On x86_64 systems:

<pre>yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm</pre>

On i386 systems:

<pre>yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm</pre>

phpMyAdmin can now be installed as follows:

<pre>yum install phpmyadmin</pre>

Now configure phpMyAdmin by changing the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> section):

<pre>vi /etc/httpd/conf.d/phpmyadmin.conf

#
# Web application to manage MySQL
#

#<Directory "/usr/share/phpmyadmin">
# Order Deny,Allow
# Deny from all
# Allow from 127.0.0.1
#</Directory>

Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin</pre>

Next we change the authentication in phpMyAdmin from cookie to http:

<pre>vi /usr/share/phpmyadmin/config.inc.php

[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]</pre>

Restart Apache:

<pre>/etc/init.d/httpd restart</pre>

Afterwards, you can access phpMyAdmin under IPAddress/phpmyadmin/ in your browser.

=== OS Ticket ===

If you get the below error on Cent OS when going to:

* Admin Panel
* Emails tab
* click the email account
* set it to Enabled and to use IMAP
* then click Save Changes

"'''IMAP doesn't exist. PHP must be compiled with IMAP enabled.'''"

Do the following in SSH:

<pre>yum install php-imap
/etc/init.d/httpd restart</pre>

You may also need php-imap.x86_64

The filename above (/usr/local/etc/playlist-filename.txt) that you specify needs to match the file you specified in the ezstream_mp3.xml file. The find command above is an example.

I use the below syntax so I do not have a random order and sort alphabetically by Artist and order by Track Order:

<pre>find /usr/local/etc/mu -name *mp3 -type f | sort -g > /usr/local/etc/playlist-icecast.txt

vim ezstream_mp3.xml
#specify the full filepath to your playlist.txt file</pre>

Ensure you have:

- In ezstream_mp3.xml the URL in the form http://0.0.0.0:port/mountpoint and the filename as the full filepath of your playlist .txt, .m3u or .ogg

- In icecast.xml the accesslog and errorlog should just be /access.log and /error.log and the logdir should just be /var/log/icecast

<pre>su icecast
icecast -c /usr/local/etc/icecast.xml
#Close the SSH session but do not CTRL + C the operating. Open another SSH session

ezstream -c /usr/local/etc/ezstream_mp3.xml
#Close the SSH session but do not CTRL + C the operating.</pre>

Open another SSH session to do any further work on the server and the processes will continue to run in the background. Add the following command to /etc/rc.local to have it start on boot:

<pre>icecast -c /usr/local/etc/icecast.xml -b</pre>

phpize ; ./configure ; make ; make install</pre>

It will then show something like ''Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-00000000/'' . So then do:

<pre>vim /usr/local/lib/php.ini
/extension_dir

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-00000000"
extension="ffmpeg.so"

php -i | grep ffmpeg</pre>

It should then show:

<pre>ffmpeg
ffmpeg-php version => 0.6.0-svn
ffmpeg-php built on => Jul 19 2012 15:07:59
ffmpeg-php gd support => disabled
ffmpeg libavcodec version => Lavc52.123.0
ffmpeg libavformat version => Lavf52.111.0
ffmpeg swscaler version => SwS0.14.1
ffmpeg.allow_persistent => 0 => 0
ffmpeg.show_warnings => 0 => 0</pre>

Following are the file system paths of tools that you installed:

<pre>ffmpeg: /usr/bin/ffmpeg
mplayer: /usr/bin/mplayer
mencoder: /usr/bin/mencoder
flvtool2: /usr/bin/flvtool2
MP4Box: /usr/bin/MP4Box</pre>

<pre>vim /etc/yum.conf</pre>

Take out ruby* from exclude= line and save the file

<pre>yum -y install flvtool2.noarch</pre>

<pre>vim /etc/yum.conf</pre>

Take out apache2* and httpd* from exclude= line and save the file. From [http://pkgs.org/centos-6-rhel-6/epel-x86_64/mod_flvx-0-0.1.20100525git.el6.x86_64.rpm.html#files this link] you get:

<pre>wget http://dl.fedoraproject.org/pub/epel/6/x86_64/mod_flvx-0-0.1.20100525git.el6.x86_64.rpm
rpm -ivh mod_flvx-0-0.1.20100525git.el6.x86_64.rpm --nodeps</pre>

Do not configure these manually, especially don't fiddle with glibc, can of worms and fail ahoy:

<pre>config(mod_flvx) = 0-0.1.20100525git.el6
httpd-mmn = 20051115
libc.so.6()(64bit)
libc.so.6(GLIBC_2.2.5)(64bit)</pre>
[http://www.linuxquestions.org/questions/linux-software-2/which-rpm-contains-rtld-gnu_hash-627020 rtld(GNU_HASH)], part of glibc

Doing yum install mod_flvx.x86_64 will ask you to downgrade httpd/apache from 2.2.22 to 2.2.15-15 ( 2.2.15-15.el6.centos.1 ) so be careful with this or do not do this.

Alternate mod_flvx guides: [http://www.mosalov.com/wiki/Flash_streaming_with_mod_flvx 1], [http://24x7servermanagement.com/blog/?p=803 2], [http://www.gnutoolbox.com/mod_flvx 3] and [http://journal.paul.querna.org/articles/2006/07/11/mod_flvx 4]

Then follow [http://wiki.phpmotion.com/PHPShield53 these] instructions to install PHP Shield. You may need 757, 775 or 777 for the following folders: addons, classes, logs, pictures, setup, temp and uploads.

Run through the installer either via your domain name or on a cPanel server do serverip/~ftpuser . Then after it has all been completed do:

<pre>cd /documentroot
#e.g. cd /home/DomainWithoutSuffix/public_html
rm -y setup/ -R</pre>
/etc/init.d/httpd restart
==== CentOS 5 ====

These instructions will install ffmpeg + ffmpeg-devel + ffmpeg-php, mplayer, mencoder, flv2tool and LAME MP3 encoder.

<pre>uname -i

rpm -Uvh http://mirrors.coreix.net/fedora-epel/5/x86_64/epel-release-5-4.noarch.rpm

yum -y install gpac gpac-libs
yum -y install ffmpeg-devel
wget http://downloads.sourceforge.net/ffmpeg-php/ffmpeg-php-0.6.0.tbz2
cd to the directory, potentially /usr/src

== Unable to find packages/software ==

Check /etc/yum.conf and remove the software* exclude entry. By default a cPanel CentOS server may have the following within that file:

exclude=apache* bind-chroot courier* dovecot* exim* filesystem httpd* mod_ssl* mydns* mysql* nsd* perl* php* proftpd* pure-ftpd* ruby* spamassassin* squirrelmail*

== Uninstall Postfix on psa (Plesk) ==

You can do this either via:

* [[SSH]] using the command /usr/local/psa/admin/bin/autoinstaller then selecting Qmail instead of Postix (normally option 13 instead of 14) or
* via the GUI interface for the control panel:

Server Management - Tools & Utilities/Settings > Panel - Updates and Upgrades > Add Components - Untick "Show only not installed components" > Different mailservers - Qmail Mailserver

When searching for software or loading any program, you will get: "the permission of the setuid helper is not correct". To fix this do cd /etc/lib64/dbus-1 and run chmod 4750 dbus-daemon-launch-helper (default is 750).

When running /sbin/service vncserver start if it says:

<pre>Warning: hostname:1 is taken because of /tmp/.X1-lock
Remove this file if there is no X server hostname:1
A VNC server is already running as :1
[FAILED]</pre>

to kill the process, run vncserver -kill :X (X being the number of the one it believes is running, e.g :1). If this fails with:

<pre>Can't find file /root/.vnc/hostname:1.pid
You'll have to kill the Xvnc process manually</pre>

Do:

<pre>cd /tmp
rm .X1-lock
cd /tmp/.X11-unix/
rm X1
/sbin/service vncserver start</pre>
