Installing ZNC 1.0 on Fedora 8Edit

Created 7/7/2013, updated 5/18/2017

Installation

# yum install gcc-c++ # prereq
# sudo -i -u builder # build as unprivileged user
$ wget http://znc.in/releases/znc-1.0.tar.gz
$ tar xzvf znc-1.0.tar.gz
$ cd znc-1.0
$ ./configure
$ make
$ exit # back to root
# cd /home/builder/znc-1.0
# make install

Preparing an unprivileged user to run the daemon

At the very least, we want to run as an unprivileged user. For bonus points, we could run the daemon inside a chroot.

# useradd -r -m -d /var/lib/znc -c "ZNC IRC bouncer" znc

Configuring

If using an existing SSL certificate, concatenate the relevant bits (private key, certificate, CA certificate) at $HOME/.znc/znc.pem, then configure:

# chown znc:znc /var/lib/znc/.znc/znc.pem
# chmod 400 !$
# sudo -i -u znc
$ /usr/local/bin/znc --makeconf

Additionally, as I am running this on EC2, I needed to add a port to the security group to allow connections through to ZNC.

Running as a daemon

The docs (suprisingly) recommend using cron to make sure the daemon is running every ten minutes:

# crontab -u znc edit

The crontab should have an entry like:

*/10 * * * *   /usr/local/bin/znc > /dev/null 2>&1
