How to Install and Configure Icecast 2 Streaming Audio Server on CentOS 8

Icecast is a high-performance, open-source streaming media audio server capable of broadcasting MP3, Ogg Vorbis, and Opus audio streams. Because prebuilt Icecast packages were initially omitted from CentOS 8 and EPEL 8 repositories, compiling from source with Vorbis and Theora audio support is required.

Environment: CentOS 8 / RHEL 8 • Icecast 2.4.x • Ogg / Vorbis / Theora Codecs

1. Install Build Tools and Codec Dependencies

yum groupinstall "Development Tools" -y
yum install curl-devel libtheora-devel libvorbis-devel libxslt-devel speex-devel libshout-devel -y

2. Download and Build Icecast

cd /usr/src
wget http://downloads.xiph.org/releases/icecast/icecast-2.4.4.tar.gz
tar -zxf icecast-2.4.4.tar.gz
cd icecast-2.4.4

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make && make install

3. Create Service User and Start Daemon

useradd -r -s /sbin/nologin icecast
chown -R icecast:icecast /var/log/icecast

# Launch Icecast as a background daemon
icecast -b -c /etc/icecast.xml

How to Rebuild Apache httpd to Change suexec AP_DOC_ROOT from /var/www to /home (CentOS & RHEL)

Standard RPM packages of Apache httpd in CentOS and RHEL compile suexec with a hardcoded document root of /var/www (--with-suexec-docroot=/var/www). However, web control panels like Virtualmin host customer accounts under /home. When suexec executes a user script under /home, it aborts with "command not in docroot". Here is how to rebuild the official upstream httpd SRPM with AP_DOC_ROOT set to /home.

Compilation Flag: --with-suexec-docroot=/home

Rebuilding the RPM

# 1. Install build tools and dependencies
yum install rpm-build redhat-rpm-config gcc make -y
yum-builddep httpd -y

# 2. Download and unpack httpd SRPM
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
cd ~/rpmbuild/SRPMS
yumdownloader --source httpd
rpm -ivh httpd-*.src.rpm

# 3. Edit SPECS/httpd.spec and modify suexec docroot
cd ~/rpmbuild/SPECS
sed -i 's|--with-suexec-docroot=/var/www|--with-suexec-docroot=/home|g' httpd.spec

# 4. Rebuild binary RPM
rpmbuild -bb httpd.spec

# 5. Install the custom suexec binary
rpm -Uvh --force ~/rpmbuild/RPMS/x86_64/httpd-*.rpm

Confirm the new docroot:

suexec -V | grep AP_DOC_ROOT
