There are several possibilities to install ZNC on your machine. The latest version is always available using the source tarball from http://znc.in/releases.
- Which way should I choose for installing ZNC?
- If you don't have root access, the only way is to use source tarball. You'll need to use
./configure --prefix="$HOME/.local"as described.
- If you have root access, you can use either source tarball or the convenient way for your distro. Check section about your distro for details, but be aware that these may contain old versions of ZNC!
Once you have installed ZNC, you can create a config file with
- 1 Development Versions
- 2 Source Tarball
- 3 Linux
- 3.1 Debian
- 3.2 Fedora/CentOS/Red Hat Enterprise Linux
- 3.3 Ubuntu
- 3.4 (open)SUSE
- 3.5 Gentoo
- 3.6 Slackware
- 3.7 Alpine Linux
- 3.8 Archlinux
- 4 FreeBSD
- 5 Mac OS X
- 6 Microsoft Windows
Read the git page if you want to get the current development version. Beware that this might have more bugs, more features, be a little unstable and eat your first born. You have been warned!
Official source tarballs can be found here.
If you want to compile ZNC with OpenSSL support, you need the OpenSSL development package. On Debian/Ubuntu this is called libssl-dev, on CentOS/Fedora/Red Hat it's openssl-devel, and on openSUSE it's libopenssl-devel.
A good way to install this and other dependencies is the build dependency feature of package managers (
apt-get build-dep /
zypper source-install --build-deps-only).
- Download the latest source tarball
tar -xzvf znc-1.6.4.tar.gz
--prefix="$HOME/.local"if you don't want a system wide installation or simply don't have root access; use
--with-openssl=/path/to/opensslif you have a non-standard SSL path)
--helpto see other configure options)
(if you are on a dedicated server and your CPU has more than one core, you can use
make -jXwhere X is the number of CPU cores to speed up compilation)
Please note that compiling can take 5-10 minutes or more.
Once you have installed znc, you can use
znc --makeconf to make a configuration file for ZNC. This config is stored in ~/.znc under the user you run it as. You should create a dedicated non root user to run znc under.
ZNC is run by just executing
znc under the dedicated znc user, at which stage it goes to background. It does automatically not make an init.d service for itself (which can be done by following the instructions to running ZNC as a system daemon) nor does it need to be run in screen or something similar.
- See the FAQ page if you encounter problems.
|Prior to Debian Sid (Unstable) including Wheezy, Squeeze, and Lenny, the ZNC packages included in the repositories for those older releases are extremely old. There could be security issues and even bugs in the code. If you are having issues with ZNC from your Debian package manager (prior to Sid), it is recommended to uninstall that package and build from source, or use the third-party repository (noted below).|
|There is a third-party repository provided by Thomas W. which has updated Debian packages for Debian Wheezy and later. They are based directly off of the latest Debian packages in Debian's unstable or experimental repositories, and are built in a similar way to the PPAs. Details on the repository, and how to use it.|
Debian provides ZNC packages which may be installed using:
aptitude install znc
If you want to build znc from source to get a newer version than Debian provides, you may need the following packages:
build-essential libssl-dev libperl-dev pkg-config libicu-dev
You can use the command
aptitude build-dep znc
to install build dependencies automatically. Note that sometimes these build-depedencies are outdated and won't work with the current version of ZNC.
Fedora/CentOS/Red Hat Enterprise Linux
Fedora has znc packaged in it's main repository and their Extra Packages for Enterprise Linux (EPEL) repository provides them for CentOS/RHEL.
If using RHEL install the EPEL repository by downloading the appropriate package linked on EPEL's website.
Once you have EPEL installed (or are on Fedora), execute:
sudo yum install znc
Once installed you can configure znc by running:
sudo -u znc znc --makeconf # this creates /var/lib/znc/.znc
Then finally to start it you can run:
sudo systemctl start znc # or enable if you want it to autostart
You can either build ZNC from source, or use a PPA that was made by a community member to contain pre-built ZNC packages for all supported Ubuntu releases. Note that the PPA does not contain packages for every Ubuntu release, and the support dates for various Ubuntu versions is detailed here. If the release of Ubuntu you are on is not supported on the PPA, you will have to compile it from source yourself.
Build From Source
If you want to build znc from source to get a newer version than Ubuntu provides, you may need to determine capability of your system to build ZNC 1.6.0 (and newer) based on the version of Ubuntu.
Building from Git Master
|If you are building from a source tarball for a stable release, skip this section. It is only needed for those building the development release (the master branch) on Git.|
If you are trying to use the Git master version of the source code, then you will also need to ensure the following packages are also installed. You will not need to install these if you are using a stable release tarball, only if you are using Git master:
aclocal pkg-config automake autoconf
After you have installed these packages, then continue onward for the additional dependencies you will need.
After installing dependencies, you will have to run autogen.sh to generate the configure script.
Add Build Dependency Sources
Older than Ubuntu 12.04
If you have any version of Ubuntu older than 12.04, you are incapable of building ZNC 1.6 or newer, due to the inability to install or build the ZNC build dependencies.
If you are on Ubuntu 12.04, you will need to add three PPAs to your system, with the following commands:
sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test sudo add-apt-repository -y ppa:teward/swig3.0 sudo add-apt-repository -y ppa:teward/icu-backports
If you are on Ubuntu 14.04, you will need to add one PPA to your system, with the following command:
sudo add-apt-repository -y ppa:teward/swig3.0
Newer than Ubuntu 14.04
You will not need any additional PPAs or sources for build dependencies.
Other Build Dependencies
After verifying you have the required build dependency sources, you will need to install the following packages:
build-essential libssl-dev libperl-dev pkg-config swig3.0 libicu-dev
If you are on Ubuntu 12.04, you will also need to install the following package:
After you have done this, you can follow the instructions on this page for compiling from the source tarball.
Install via PPA
|Debian users: do not use this PPA or you will risk forfeiting all support from Debian or breaking your system! Use the Debian repository described on the Debian section instead.|
A Personal Package Archive (PPA) has been created by Thomas W., and contains the latest stable ZNC release as exists in Debian. It contains packages for all releases of Ubuntu that are currently supported. It does not contain packages for versions of Ubuntu that are past their end of life dates. Click here if you wish to see the details of the packages in the PPA. NOTE: This PPA contains packages for only certain Ubuntu releases, as detailed here.
The versions of ZNC currently available in the PPA are detailed on this page.
First, make sure you have the python-software-properties package installed:
sudo apt-get install python-software-properties software-properties-common
Then, add the PPA to your sources, and update the apt information:
sudo add-apt-repository ppa:teward/znc sudo apt-get update
Then, install the znc packages:
sudo apt-get install znc znc-dbg znc-dev znc-perl znc-python znc-tcl
ZNC is now installed. You can create the configuration normally with this, when run on the user that you want to run ZNC as:
ZNC is part of the official repositories. To install, use the YaST GUI or install via commandline by typing
zypper install znc
Gentoo provides ZNC packages which may be installed using:
emerge -av net-irc/znc
Several USE Flags can be used for znc:
- daemon (local): (not offically supported) Allow znc to run as a system-wide service. Installs an init script and creates a znc user:group.
- debug (global): enable debug
- ipv6 (global): adds support for ipv6
- perl (global): adds support for writing perl modules
- python (global): adds support for writing python 3 modules
- ssl (global): enable secure socket layer connections
- sasl (global): sasl support
- tcl (global): adds support for writing tcl modules
equery uses znc -aWill print you a list of USE flags that will be used for znc
To install znc from the package manager, enter the following command:
sudo apk add znc znc-extra znc-modperl znc-modpython znc-modtcl ca-certificates
If you want to build znc from source to get a newer version than Alpine provides, you need to install packages with the following command:
sudo apk add autoconf automake gettext-dev g++ make openssl-dev pkgconfig zlib-dev
sudo apk add git gdb perl-dev python3-dev swig tcl-dev cyrus-sasl-dev
ZNC is part of the archlinux package repository, and can be installed with the following:
pacman -S znc
Additionally you can install the following optional dependencies to add support for additional modules.
- cyrus-sasl - saslauth module
- perl - modperl module
- python - modpython module
- tcl - modtcl module
rc.d scripts (deprecated)
You may also be interested in rc.d scripts for znc which can be installed with:
You can read more about these scripts here. As of November 2012, initscripts support is being phased-out and expected to be totally deprecated in early 2013. Systemd scripts are already distributed in the package. The Archlinux wiki has some helpful information for new users who are getting started with znc.
You can install the latest git snapshot from the Arch User Repository.
ZNC is in FreeBSD ports, just do:
cd /usr/ports/irc/znc make config make install clean
pkg_add -r znc
Mac OS X
There are two ways to install ZNC on OS X, either using a package manager such as Homebrew or installing it yourself from source. See this blog post for a tutorial on how to compile ZNC from source.
- NOTE: If you are running on PPC architecture and cannot make the ./configure && make && sudo make install dance work, you'll want to do the following:
- Make sure that you're using the --disable-perl switch for configure. Hence: ./configure --prefix=/usr/local --disable-perl
For more information about Homebrew see here. The following command will install Homebrew to /usr/local
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Homebrew requires Xcode and Mac OS X >= 10.5
Installing znc with Homebrew
brew install znc
Installing znc with MacPorts
port install znc
Warning: If you're going to install ZNC on your local Windows machine, it will probably be useless. You should run it on some machine (Windows or not), which is connected to internet 24/7.
ZNC is available in list of cygwin packages.
Download Cygwin, install it. When choosing list of packages to install, search for "znc".
If you don't want to use the provided packages, you can compile ZNC from source; for that you'll need the following packages installed: automake, gcc-g++, libicu-devel, make, mpfr, pkg-config, openssl-devel, zlib-devel. After installing these packages proceed to source tarball section (or git)
