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.
If you're looking for the one-liner to install salt...
For example, using curl to install latest git:
curl -L http://bootstrap.saltstack.org | sudo sh -s -- git developIf you have certificate issues using curl, try the following:
curl --insecure -L http://bootstrap.saltstack.org | sudo sh -s -- git developUsing wget to install your distribution's stable packages:
wget -O - http://bootstrap.saltstack.org | sudo shIf you have certificate issues using wget try the following:
wget --no-check-certificate -O - http://bootstrap.saltstack.org | sudo shIf you already have python installed, python 2.6, then it's as easy as:
python -m urllib "http://bootstrap.saltstack.org" | sudo sh -s -- git developAll python versions should support the following one liner:
python -c 'import urllib; print urllib.urlopen("http://bootstrap.saltstack.org").read()' | \
sudo sh -s -- git developOn a FreeBSD base system you usually don't have either of the above binaries available. You do
have fetch available though:
fetch -o - http://bootstrap.saltstack.org | sudo shIf all you want is to install a salt-master using latest git:
curl -L http://bootstrap.saltstack.org | sudo sh -s -- -M -N git developIn order to install salt for a distribution you need to define:
- To Install Dependencies, which is required, one of:
install_<distro>_<major_version>_<install_type>_deps
install_<distro>_<major_version>_<minor_version>_<install_type>_deps
install_<distro>_<major_version>_deps
install_<distro>_<major_version>_<minor_version>_deps
install_<distro>_<install_type>_deps
install_<distro>_deps- Optionally, define a minion configuration function, which will be called if the
-c|config-diroption is passed. One of:
config_<distro>_<major_version>_<install_type>_salt
config_<distro>_<major_version>_<minor_version>_<install_type>_salt
config_<distro>_<major_version>_salt
config_<distro>_<major_version>_<minor_version>_salt
config_<distro>_<install_type>_salt
config_<distro>_salt
config_salt [THIS ONE IS ALREADY DEFINED AS THE DEFAULT]- To install salt, which, of course, is required, one of:
install_<distro>_<major_version>_<install_type>
install_<distro>_<major_version>_<minor_version>_<install_type>
install_<distro>_<install_type>- Optionally, define a post install function, one of:
install_<distro>_<major_version>_<install_type>_post
install_<distro>_<major_version>_<minor_version>_<install_type>_post
install_<distro>_<major_version>_post
install_<distro>_<major_version>_<minor_version>_post
install_<distro>_<install_type>_post
install_<distro>_post- Optionally, define a start daemons function, one of:
install_<distro>_<major_version>_<install_type>_restart_daemons
install_<distro>_<major_version>_<minor_version>_<install_type>_restart_daemons
install_<distro>_<major_version>_restart_daemons
install_<distro>_<major_version>_<minor_version>_restart_daemons
install_<distro>_<install_type>_restart_daemons
install_<distro>_restart_daemonsAttention!
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:
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.
