Be sure to :ref:`create an admin user` before starting CouchDB! .. _install/unix/binary: Installation using the Apache CouchDB convenience binary packages ================================================================= If you are running one of the following operating systems, the easiest way to install CouchDB is to use the convenience binary packages: * CentOS/RHEL 7 * CentOS/RHEL 8 * CentOS/RHEL 9 (with caveats) * Debian 10 (buster) * Debian 11 (bullseye) * Debian 12 (bookworm) * Ubuntu 18.04 (bionic) * Ubuntu 20.04 (focal) * Ubuntu 22.04 (jammy) These RedHat-style rpm packages and Debian-style deb packages will install CouchDB at ``/opt/couchdb`` and ensure CouchDB is run at system startup by the appropriate init subsystem (SysV-style initd or systemd). The Debian-style deb packages *also* pre-configure CouchDB as a standalone or clustered node, prompt for the address to which it will bind, and a password for the admin user. Responses to these prompts may be pre-seeded using standard ``debconf`` tools. Further details are in the `README.Debian`_ file. .. _README.Debian: https://github.com/apache/couchdb-pkg/blob/main/debian/README.Debian For distributions lacking a compatible SpiderMonkey library, Apache CouchDB also provides packages for the 1.8.5 version. Enabling the Apache CouchDB package repository ---------------------------------------------- .. highlight:: sh **Debian or Ubuntu**: Run the following commands:: sudo apt update && sudo apt install -y curl apt-transport-https gnupg curl https://couchdb.apache.org/repo/keys.asc | gpg --dearmor | sudo tee /usr/share/keyrings/couchdb-archive-keyring.gpg >/dev/null 2>&1 source /etc/os-release echo "deb [signed-by=/usr/share/keyrings/couchdb-archive-keyring.gpg] https://apache.jfrog.io/artifactory/couchdb-deb/ ${VERSION_CODENAME} main" \ | sudo tee /etc/apt/sources.list.d/couchdb.list >/dev/null **RedHat(<9) or CentOS**: Run the following commands:: sudo yum install -y yum-utils sudo yum-config-manager --add-repo https://couchdb.apache.org/repo/couchdb.repo **RedHat(>=9)**: Run the following commands:: sudo yum install -y yum-utils sudo yum-config-manager --add-repo https://couchdb.apache.org/repo/couchdb.repo # Enable EPEL for the SpiderMonkey dependency sudo dnf config-manager --set-enabled crb sudo dnf install epel-release epel-next-release Installing the Apache CouchDB packages -------------------------------------- .. highlight:: sh **Debian or Ubuntu**: Run the following commands:: sudo apt update sudo apt install -y couchdb Debian/Ubuntu installs from binaries can be pre-configured for single node or clustered installations. For clusters, multiple nodes will still need to be joined together and configured consistently across all machines; **follow the** :ref:`Cluster Setup ` **walkthrough** to complete the process. **RedHat(<9)/CentOS**: Run the command:: sudo yum install -y couchdb **RedHat(>=9)**: Run the following commands:: sudo yum install -y mozjs78 sudo yum install -y couchdb Once installed, :ref:`create an admin user` by hand before starting CouchDB, if your installer didn't do this for you already. You can now start the service. **Your installation is not complete. Be sure to complete the** :ref:`Setup ` **steps for a single node or clustered installation.** **Relax!** CouchDB is installed and running. GPG keys used for signing the CouchDB repositories -------------------------------------------------- As of 2021.04.25, the *repository* signing key for both types of supported packages is:: pub rsa8192 2015-01-19 [SC] 390EF70BB1EA12B2773962950EE62FB37A00258D uid The Apache Software Foundation (Package repository signing key) As of 2021.04.25, the *package* signing key (only used for ``rpm`` packages) is:: pub rsa4096 2017-07-28 [SC] [expires: 2022-07-27] 2EC788AE3F239FA13E82D215CDE711289384AE37 uid Joan Touzet (Apache Code Signing Key) As of 2021.11.13, the *package* signing key (only used for ``rpm`` packages) is:: pub rsa4096 2019-09-05 [SC] [expires: 2039-01-02] 0BD7A98499C4AB41C910EE65FC04DFBC9657A78E uid Nicolae Vatamaniuc uid default All are available from most popular GPG key servers. The ``rpm`` signing keys should be listed in the `KEYS `_ list as well. Installation from source ======================== The remainder of this document describes the steps required to install CouchDB directly from source code. This guide, as well as the INSTALL.Unix document in the official tarball release are the canonical sources of installation information. However, many systems have gotchas that you need to be aware of. In addition, dependencies frequently change as distributions update their archives. .. _install/unix/dependencies: Dependencies ============ You should have the following installed: * `Erlang OTP (24.x, 25.x) `_ * `ICU `_ * `OpenSSL `_ * `Mozilla SpiderMonkey (1.8.5, 60, 68, 78, 91) `_ * `GNU Make `_ * `GNU Compiler Collection `_ * `help2man `_ * `Python (>=3.6) for docs and tests `_ * Java (required for `nouveau`, minimum version 11, recommended version 19 or 20) help2man is only need if you plan on installing the CouchDB man pages. Documentation build can be disabled by adding the ``--disable-docs`` flag to the ``configure`` script. Debian-based Systems -------------------- You can install the dependencies by running:: sudo apt-get --no-install-recommends -y install \ build-essential pkg-config erlang \ libicu-dev libmozjs185-dev Be sure to update the version numbers to match your system's available packages. RedHat-based (Fedora, CentOS, RHEL) Systems ------------------------------------------- You can install the dependencies by running:: sudo yum install autoconf autoconf-archive automake \ erlang-asn1 erlang-erts erlang-eunit gcc-c++ \ erlang-os_mon erlang-xmerl erlang-erl_interface help2man \ libicu-devel libtool perl-Test-Harness Warning: To build a release for CouchDB the erlang-reltool package is required, yet on CentOS/RHEL this package depends on erlang-wx which pulls in wxGTK and several X11 libraries. If CouchDB is being built on a console only server it might be a good idea to install this in a separate step to the rest of the dependencies, so that the package and all its dependencies can be removed using the ``yum history`` tool after the release is built. (reltool is needed only during release build but not for CouchDB functioning) The package can be installed by running:: sudo yum install erlang-reltool Fedora 36 --------- On Fedora 36, you may need these packages in addition to the ones listed above: * `mozjs91-devel` * `erlang-rebar` If the system contains dangling links to Erlang chunk files, the compiler will abort. They can be deleted with the following command:: find -L /usr/lib64/erlang/lib/ -type l -name chunks | xargs rm -f Fauxton is not built on the Node.js version (v16) shipped by the system. The installation of v12.22.12 can be done via:: wget https://nodejs.org/download/release/v12.22.12/node-v12.22.12-linux-x64.tar.gz mkdir -p /usr/local/lib/nodejs tar -xvf node-v12.22.12-linux-x64.tar.gz -C /usr/local/lib/nodejs export PATH=/usr/local/lib/nodejs/node-v12.22.12-linux-x64/bin:$PATH Note that due to a problem with the Python package sphinx-build, it is not possible to compile the documentation on Fedora 36. You can skip compiling the documentation via:: ./configure --disable-docs --spidermonkey-version 91 Mac OS X -------- Follow :ref:`install/mac/homebrew` reference for Mac App installation. If you are installing from source, you will need to install the Command Line Tools:: xcode-select --install You can then install the other dependencies by running:: brew install autoconf autoconf-archive automake libtool \ erlang icu4c spidermonkey pkg-config You will need `Homebrew` installed to use the ``brew`` command. Some versions of Mac OS X ship a problematic OpenSSL library. If you're experiencing troubles with CouchDB crashing intermittently with a segmentation fault or a bus error, you will need to install your own version of OpenSSL. See the wiki, mentioned above, for more information. .. seealso:: * `Homebrew `_ FreeBSD ------- FreeBSD requires the use of GNU Make. Where ``make`` is specified in this documentation, substitute ``gmake``. You can install this by running:: pkg install gmake Installing ========== Once you have satisfied the dependencies you should run:: ./configure If you wish to customize the installation, pass ``--help`` to this script. If everything was successful you should see the following message:: You have configured Apache CouchDB, time to relax. Relax. To build CouchDB you should run:: make release Try ``gmake`` if ``make`` is giving you any problems. If include paths or other compiler options must be specified, they can be passed to rebar, which compiles CouchDB, with the ERL_CFLAGS environment variable. Likewise, options may be passed to the linker with the ERL_LDFLAGS environment variable:: make release ERL_CFLAGS="-I/usr/local/include/js -I/usr/local/lib/erlang/usr/include" If everything was successful you should see the following message:: ... done You can now copy the rel/couchdb directory anywhere on your system. Start CouchDB with ./bin/couchdb from within that directory. Relax. Note: a fully-fledged ``./configure`` with the usual GNU Autotools options for package managers and a corresponding ``make install`` are in development, but not part of the 2.0.0 release. .. _install/unix/security: User Registration and Security ============================== For OS X, in the steps below, substitute ``/Users/couchdb`` for ``/home/couchdb``. You should create a special ``couchdb`` user for CouchDB. On many Unix-like systems you can run:: adduser --system \ --shell /bin/bash \ --group --gecos \ "CouchDB Administrator" couchdb On Mac OS X you can use the Workgroup Manager to create users up to version 10.9, and dscl or sysadminctl after version 10.9. Search Apple's support site to find the documentation appropriate for your system. As of recent versions of OS X, this functionality is also included in Server.app, available through the App Store only as part of OS X Server. You must make sure that the user has a working POSIX shell and a writable home directory. You can test this by: * Trying to log in as the ``couchdb`` user * Running ``pwd`` and checking the present working directory As a recommendation, copy the ``rel/couchdb`` directory into ``/home/couchdb`` or ``/Users/couchdb``. Ex: copy the built couchdb release to the new user's home directory:: cp -R /path/to/couchdb/rel/couchdb /home/couchdb Change the ownership of the CouchDB directories by running:: chown -R couchdb:couchdb /home/couchdb Change the permission of the CouchDB directories by running:: find /home/couchdb -type d -exec chmod 0770 {} \; Update the permissions for your ini files:: chmod 0644 /home/couchdb/etc/* First Run ========= .. note:: Be sure to :ref:`create an admin user` before trying to start CouchDB! You can start the CouchDB server by running:: sudo -i -u couchdb /home/couchdb/bin/couchdb This uses the ``sudo`` command to run the ``couchdb`` command as the ``couchdb`` user. When CouchDB starts it should eventually display following messages:: {database_does_not_exist,[{mem3_shards,load_shards_from_db,"_users" ... Don't be afraid, we will fix this in a moment. To check that everything has worked, point your web browser to:: http://127.0.0.1:5984/_utils/index.html From here you should verify your installation by pointing your web browser to:: http://localhost:5984/_utils/index.html#verifyinstall **Your installation is not complete. Be sure to complete the** :ref:`Setup ` **steps for a single node or clustered installation.** Running as a Daemon =================== CouchDB no longer ships with any daemonization scripts. The CouchDB team recommends `runit `_ to run CouchDB persistently and reliably. According to official site: *runit* is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes. It runs on GNU/Linux, \*BSD, MacOSX, Solaris, and can easily be adapted to other Unix operating systems. Configuration of runit is straightforward; if you have questions, contact the CouchDB `user mailing list `_ or `IRC-channel #couchdb `_ in FreeNode network. Let's consider configuring runit on Ubuntu 18.04. The following steps should be considered only as an example. Details will vary by operating system and distribution. Check your system's package management tools for specifics. Install runit:: sudo apt-get install runit Create a directory where logs will be written:: sudo mkdir /var/log/couchdb sudo chown couchdb:couchdb /var/log/couchdb Create directories that will contain runit configuration for CouchDB:: sudo mkdir /etc/sv/couchdb sudo mkdir /etc/sv/couchdb/log Create /etc/sv/couchdb/log/run script:: #!/bin/sh exec svlogd -tt /var/log/couchdb Basically it determines where and how exactly logs will be written. See ``man svlogd`` for more details. Create /etc/sv/couchdb/run:: #!/bin/sh export HOME=/home/couchdb exec 2>&1 exec chpst -u couchdb /home/couchdb/bin/couchdb This script determines how exactly CouchDB will be launched. Feel free to add any additional arguments and environment variables here if necessary. Make scripts executable:: sudo chmod u+x /etc/sv/couchdb/log/run sudo chmod u+x /etc/sv/couchdb/run Then run:: sudo ln -s /etc/sv/couchdb/ /etc/service/couchdb In a few seconds runit will discover a new symlink and start CouchDB. You can control CouchDB service like this:: sudo sv status couchdb sudo sv stop couchdb sudo sv start couchdb Naturally now CouchDB will start automatically shortly after system starts. You can also configure systemd, launchd or SysV-init daemons to launch CouchDB and keep it running using standard configuration files. Consult your system documentation for more information.
