================== Bootstrapping Salt ================== Before `Salt`_ can be used for provisioning on the desired machine, the binaries need to be installed. Since `Salt`_ supports many different distributions and versions of operating systems, the `Salt`_ installation process is handled by this shell script ``bootstrap-salt.sh``. This script runs through a series of checks to determine operating system type and version to then install the `Salt`_ binaries using the appropriate methods. .. Note:: This ``README`` file is not the absolute truth to what the bootstrap script is capable to do, for that, please read the generated help by passing ``-h`` to the script or even better, `read the source`_. .. _`read the source`: https://github.com/saltstack/salt-bootstrap/blob/develop/bootstrap-salt.sh **In case you found a bug, please read** `I found a bug`_ **first before submitting a new issue.** Bootstrap --------- If you're looking for the *one-liner* to install salt, please scroll to the bottom and use the instructions for *Installing via an Insecure One-Liner*. .. Attention:: The following examples are provided as an helpful and short way to install Salt. The URL used is just an HTTP redirect and as such it **will**, most likely, make either ``curl`` or ``wget`` or ``fetch`` (in FreeBSD >= 10), to complain about certificate issues. If this worries you, you **should not** use this URL. Use instead:: https://github.com/saltstack/salt-bootstrap/raw/develop/bootstrap-salt.sh Examples ~~~~~~~~ .. Note:: In every two-step example, you would be well-served to examine the downloaded file and examine it to ensure that it does what you expect. Using ``curl`` to install latest git: .. code:: console curl -L http://bootstrap.saltstack.org -o install_salt.sh sudo sh install_salt.sh git develop If you have certificate issues using ``curl``, try the following: .. code:: console curl --insecure -L http://bootstrap.saltstack.org -o install_salt.sh sudo sh install_salt.sh git develop .. Note:: The above method redirects to the raw file on Github and thus bypasses certificate checks. If you wish not to bypass certificate identification, you may use the following to download the installation script with curl: .. code:: console curl -L https://raw.github.com/saltstack/salt-bootstrap/stable/bootstrap-salt.sh -o install_salt.sh Using ``wget`` to install your distribution's stable packages: .. code:: console wget -O install_salt.sh http://bootstrap.saltstack.org sudo sh install_salt.sh If you have certificate issues using ``wget`` try the following: .. code:: console wget --no-check-certificate -O install_salt.sh http://bootstrap.saltstack.org sudo sh install_salt.sh Alternatively, if you wish not to bypass the certification verification step you may download the script without a redirect: wget -O install_salt.sh https://raw.github.com/saltstack/salt-bootstrap/stable/bootstrap-salt.sh sudo sh install_salt.sh Install a specific version from git using ``wget``: .. code:: console wget -O install_salt.sh http://bootstrap.saltstack.org sudo sh install_salt.sh -P git v0.16.4 If you already have python installed, ``python 2.6``, then it's as easy as: .. code:: console python -m urllib "http://bootstrap.saltstack.org" > install_salt.sh sudo sh install_salt.sh git develop All python versions should support the following one liner: .. code:: console python -c 'import urllib; print urllib.urlopen("http://bootstrap.saltstack.org").read()' > install_salt.sh sudo sh install_salt.sh git develop On a FreeBSD base system you usually don't have either of the above binaries available. You **do** have ``fetch`` available though: .. code:: console fetch -o install_salt.sh http://bootstrap.saltstack.org sudo sh install_salt.sh For FreeBSD >= 10 you might need to make fetch ignore the certificate issue: .. code:: console fetch --no-verify-peer -o install_salt.sh http://bootstrap.saltstack.org sudo sh install_salt.sh .. Note:: The above method redirects to the raw file on Github and thus bypasses certificate checks. If you wish not to bypass certificate identification, you may use the following to download the installation script with curl: .. code:: console fetch -o install_salt.sh install_salt.sh https://raw.github.com/saltstack/salt-bootstrap/stable/bootstrap-salt.sh sudo sh install_salt.sh If all you want is to install a ``salt-master`` using latest git: .. code:: console curl -o salt_install.sh -L http://bootstrap.saltstack.org sudo sh salt_install.sh -M -N git develop If you want to install a specific release version (based on the git tags): .. code:: console curl -o salt_install.sh -L http://bootstrap.saltstack.org sudo sh salt_install.sh git v0.16.4 To install a specific branch from a git fork: .. code:: console curl -o salt_install.sh -L http://bootstrap.saltstack.org sudo sh salt_install.sh -g https://github.com/myuser/salt.git git mybranch Installing via an Insecure One-Liner ------------------------------------ The following examples illustrate how to install Salt via a one-liner. .. Note:: Warning! These methods do not involve a verification step and assume that the delivered file is trustworthy. Examples ~~~~~~~~ Installing the latest develop branch of Salt: .. code:: console curl -L http://bootstrap.saltstack.org | sudo sh -s -- git develop Any of the example above which use two-lines can be made to run in a single-line configuration with minor modifications. Adding support for other operating systems ------------------------------------------ In order to install salt for a distribution you need to define: 1. To Install Dependencies, which is required, one of: .. code:: bash install____deps install_____deps install___deps install____deps install___deps install__deps 2. Optionally, define a minion configuration function, which will be called if the ``-c|config-dir`` option is passed. One of: .. code:: bash config____salt config_____salt config___salt config____salt config___salt config__salt config_salt [THIS ONE IS ALREADY DEFINED AS THE DEFAULT] 3. Optionally, define a salt master pre-seed function, which will be called if the -k (pre-seed master keys) option is passed. One of: .. code:: bash pressed____master pressed_____master pressed___master pressed____master pressed___master pressed__master pressed_master [THIS ONE IS ALREADY DEFINED AS THE DEFAULT] 4. To install salt, which, of course, is required, one of: .. code:: bash install___ install____ install__ 5. Optionally, define a post install function, one of: .. code:: bash install____post install_____post install___post install____post install___post install__post 6. Optionally, define a start daemons function, one of: .. code:: bash install____restart_daemons install_____restart_daemons install___restart_daemons install____restart_daemons install___restart_daemons install__restart_daemons .. admonition:: Attention! The start daemons function should be able to restart any daemons which are running, or start if they're not running. ---- Below is an example for Ubuntu Oneiric(the example may not be up to date with the script): .. code:: bash install_ubuntu_11_10_deps() { apt-get update apt-get -y install python-software-properties add-apt-repository -y 'deb http://us.archive.ubuntu.com/ubuntu/ oneiric universe' add-apt-repository -y ppa:saltstack/salt } install_ubuntu_11_10_post() { add-apt-repository -y --remove 'deb http://us.archive.ubuntu.com/ubuntu/ oneiric universe' } install_ubuntu_stable() { apt-get -y install salt-minion } install_ubuntu_restart_daemons() { for fname in minion master syndic; do # Skip if not meant to be installed [ $fname = "minion" ] && [ $INSTALL_MINION -eq $BS_FALSE ] && continue [ $fname = "master" ] && [ $INSTALL_MASTER -eq $BS_FALSE ] && continue [ $fname = "syndic" ] && [ $INSTALL_SYNDIC -eq $BS_FALSE ] && continue if [ -f /sbin/initctl ]; then # We have upstart support /sbin/initctl status salt-$fname > /dev/null 2>&1 if [ $? -eq 0 ]; then # upstart knows about this service, let's stop and start it. # We could restart but earlier versions of the upstart script # did not support restart, so, it's safer this way /sbin/initctl stop salt-$fname > /dev/null 2>&1 /sbin/initctl start salt-$fname > /dev/null 2>&1 [ $? -eq 0 ] && continue # We failed to start the service, let's test the SysV code bellow fi fi /etc/init.d/salt-$fname stop > /dev/null 2>&1 /etc/init.d/salt-$fname start done } Since there is no ``install_ubuntu_11_10_stable()`` it defaults to the unspecified version script. The bootstrapping script must be plain POSIX sh only, **not** bash or another shell script. By design the targeting for each operating system and version is very specific. Assumptions of supported versions or variants should not be made, to avoid failed or broken installations.
