Rohitt Vashishtha 95ba947f13 setup-cerbot: Allow issuing certificates for multiple domains.
This commit allows specifying Subject Alternative Names to issue certs
for multiple domains using certbot. The first name passed to certbot-auto
becomes the common name for the certificate; common name and the other
names are then added to the SAN field. All of these arguments are now
positional. Also read the following for the certbot syntax reference:

Fixes #10674.

Tim Abbott 453c35d0f7 install: Provide a suggestive error message when missing Universe.
By far the dominant cause of errors when installing apt packages is
not having the Universe repository enabled in Ubuntu bionic (this
seems to have started happening a lot recently; I wonder if Ubuntu
changed the defaults for new server installs or something?).

In any case, providing that suggestion in the error output should help
reduce these a lot.

Tim Abbott e7bb833a37 install: Improve some error output for common errors.
This uses `set +x` to hide the `echo` output, and then sets the font
color to red.

Tim Abbott a7d7d181ea install: Ensure that sudo is installed.
We use it to drop privileges from root to other users in the installer
process (which ideally, we would remove, but it will take some
annoying refactoring).

This should generally be safe to do, since the default sudo
permissions only allow root to use it anyway.

See https://github.com/zulip/zulip/issues/10036 for the follow-up
issue of removing the need to do this.

Tim Abbott 9054ce278f locale: Fix incorrect use of locale-gen to generate locales.
Previously, we were having issues installing on Debian Stretch with
non-English locales, because `locale-gen` actually doesn't take a
locale as an argument (and thus `locale-gen en_US.UTF-8` did nothing).
We should instead be calling localedef directly.

Thanks to Tom Daff for debugging this.

Fixes #10629.

xificurC 9e053c74cf scripts: Allow configuring a custom CA bundle for build process.
For building Zulip in an environment where a custom CA certificate is
required to access the public Internet, one needs to be able to
specify that CA certificate for all network access done by the Zulip
installer/build process.  This change allows configuring that via the
environment.

Tim Abbott ee0f4ca330 locale: Set LANG/LANGUAGE to match LC_ALL.
Apparently, perl at least expects LANG, LANGUAGE, and LC_ALL to be
consistent, and thus apt spits out a bunch of warnings if these are
different.  So if we're forcing LC_ALL in these installer/upgrade
script blocks, we should force the rest too.

I believe this fixes the remaining locale part of #9946.

Tim Abbott f228eabd90 install: Make sure the en_US.UTF-8 locale is available.
We need to make sure the en_US.UTF-8 locale has been generated before
setting the locale via the environment.

Joshua Schmidlkofer b1a57d144f thumbor: Add production installer/puppet support.
This commits adds the necessary puppet configuration and
installer/upgrade code for installing and managing the thumbor service
in production.  This configuration is gated by the 'thumbor.pp'
manifest being enabled (which is not yet the default), and so this
commit should have no effect in a default Zulip production environment
(or in the long term, in any Zulip production server that isn't using
thumbor).

Credit for this effort is shared by @TigorC (who initiated the work on
this project), @joshland (who did a great deal of work on this and got
it working during PyCon 2017) and @adnrs96, who completed the work.

Tim Abbott 61ee01359e install: Update list of supported distros for installation.
This only changes the install script, not the docs, so it's pretty
low-profile; we'll update the docs after a bit more testing.

Tim Abbott 8a66b0b9a9 docker: Set has_appserver=0 correctly.
The docker installer configuration incorrectly had has_appserver set
to 0; this meant that (A) the docker-zulip code needed to copy the
block of code in the installer for the `has_appserver` case into the
Dockerfile (unnecessarily), and (B) one couldn't use `install` from a
Git ref (because the static asset compiler didn't end up in the right
place).

It appears that docker-zulip tried to set this flag in their `install`
command line, but the construction inside `install` meant that didn't
work.

Tim Abbott 1b3b298fa8 install: Allow installing with Debian 9.

Greg Price e8be968250 install: Expand error message for missing SSL cert slightly.
It wasn't obvious reading this message that you can perfectly well
bring your own SSL/TLS certificate; unless you read quite a bit
between the lines where we say "could not find", or followed the link
to the detailed docs, the message sounded like you had to either use
--certbot or --self-signed-cert.

So, explicitly mention the BYO option.  Because the "complete chain"
requirement is a bit tricky, don't try to give instructions for it
in this message; just refer the reader to the docs.

Also, drop the logic to identify which of the files is missing; it
certainly makes the code more complex, and I think even the error
message is actually clearer when it just gives the complete list of
required files -- it's much more likely that the reader doesn't know
what's required than that they do and have missed one, and even then
it's easy for them to look for themselves.

Tim Abbott 0d35bbc464 install: Install the wget package.
We depend on it for installing node, and it's a standard package, not
a required one, so we do need to explicitly declare the dependency.

Greg Price 678fcef5bd install: Fix up success message in `--no-init-db` case.
The installation isn't really complete here, and wasn't even when this
was the only success case; the instructions we're giving are for the
next step in the installation.

These instructions don't say what to do in an actual use case for this
option, but decent instructions there will require having a concrete
use case in front of us and designing the flow for it.  At this stage,
just say where we are in the normal flow, and an admin who's chosen to
go off that flow can figure out how they want to vary it from there.

Greg Price f22712e8e8 install: Go straight through by default.
This flips the experimental `--express` option to be the default.

We retain the old behavior, where the script exits before
`initialize-database`, as an option `--no-init-db`; it might be useful
in e.g. a migration scenario (from a Zulip install elsewhere, or
another chat system) where the admin wants to set up the database
separately.

The install instructions are adjusted to match, getting shorter by two
steps and a bunch of words.  I think this opens up opportunities to
refactor the text to simplify things further, too, but leaving that
for another commit.

Also tweak the "production" test suite to match.

Greg Price b1ad4e88d4 install: Switch some more uses of `sudo` to `su`.
Kind of unfortunate because the `sudo` interface for running a command
is objectively better -- a list of arguments, rather than a string to
be re-parsed by the shell.  But some bare-bones machine images lack
`sudo`, so this makes things a bit more portable.

Greg Price eb7eef02e8 install: Suppress initialize-database instructions when redundant.

Greg Price 6e633f8e2f install: Use readlink -f rather than realpath.
It does exactly the same thing, though the name is less transparent; and

Greg Price 218b653930 install: Clean up organization of option parsing.

Greg Price 70d203c1c8 install: Add experimental option to go straight through more install steps.
We'll make this the normal behavior soon, once we're satisfied with
our arrangements for sending the admin straight to realm creation and
using the app without configuring email.  The instructions in the docs
will also have to change accordingly, of course.
2018-02-05 12:59:12 -08:00
Greg Price 0ba3fc3c2f install: Slightly tighten up CLI parsing.
This causes us to give an error if you pass the installer any
positional arguments, e.g. with `--`.  There's no reason you'd want
to do this, but I accidentally did it by passing an extra `--` to
the `test-install/install` wrapper and spent a few minutes on
confused debugging.

Greg Price f26b34405e install --self-signed-cert: Generate our own, rather than use system's.
This gives us just one way of adopting a self-signed cert, rather than
one script which would generate a new one and an option to another
which would symlink to the system's snakeoil cert.  Now those two
codepaths converge, and do the same thing.

The small advantage of generating our own over the alternative is that
it lets us set the name in the cert to EXTERNAL_HOST, rather than the
system's hostname as embedded in the system snakeoil certs.  Not a big
deal, but might make things go slightly smoother if some browsers are
lenient (in a way that they probably shouldn't be.)

Greg Price d76c2d77f4 install: Tighten an SSL-cert help message.

Greg Price 841a5f3152 install: Say --self-signed-cert instead of --snakeoil-cert.

Greg Price 2a59b2d2ac install: Work around a bug in the (our) Debian package for camo.
Before this fix, the installer has an extremely annoying bug where
when run inside a container with `lxc-attach`, when the installer
finishes, the `lxc-attach` just hangs and doesn't respond even to
C-c or C-z.  The only way to get the terminal back is to root around
from some other terminal to find the PID and kill it; then run
something like `stty sane` to fix the messed-up terminal settings
left behind.

After bisecting pieces of the install script to locate which step
was causing the issue, it comes down to the `service camo restart`.
The comment here indicates that we knew about an annoying bug here
years ago, and just swept it under the rug by skipping this step
when in Travis. >_<

The issue can be reproduced by running simply `service camo restart`
under `lxc-attach` instead of the installer; or `service camo start`,
following a `service camo stop`.  If `lxc-attach` is used to get an
interactive shell, these commands appear to work fine; but then when
that shell exits, the same hang appears.  So, when we start camo
we're evidently leaving some kind of mess that entangles the daemon
with our shell.

Looking at the camo initscript where it starts the daemon, there's
not much code, and one flag jumps out as suspicious:

  start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
    --exec $DAEMON --no-close -c nobody --test > /dev/null 2>&1 \
    || return 1
  start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
    --no-close -c nobody --exec $DAEMON -- \
    $DAEMON_ARGS >> /var/log/camo/camo.log 2>&1 \
    || return 2

What does `--no-close` do?

 -C, --no-close
     Do not close any file descriptor when forcing the daemon
     into  the  background  (since version 1.16.5).  Used for
     debugging purposes to see  the  process  output,  or  to
     redirect  file  descriptors  to  log the process output.

And in fact, looking in /proc/PID/fd while a hang is happening finds
that fd 0 on the camo daemon process, aka stdin, is connected to our
terminal.

So, stop that by denying the initscript our stdin in the first place.
This fixes the problem.

The Debian maintainer turns out to be "Zulip Debian Packaging Team",
at debian@zulip.com; so this package and its bugs are basically ours.

Greg Price cef8549ec6 install: Add --snakeoil-cert option.
This provides a major simplification for non-production installs,
including our own testing (it's already in both the test-install
harness script and the "production" test suite) as well as potential
admins evaluating Zulip.

Ultimately this should probably be the default behavior, with perhaps
something shown to admins on the web as a reminder and link to help on
installing a better certificate.  For now, pending working through
that, just get the behavior in and leave it opt-in.

Greg Price 525b136f10 install: Install curl.
The third-party `install-yarn.sh` script uses `curl`, and we invoke it
in `install-node`.  So we need to install it as a dependency.

We've mostly gotten away with this because it's common for `curl` to
already be installed; but it isn't always.
2018-01-22 18:55:46 -08:00
Greg Price 64c608a51a install: Clarify how we set locale during install, and why.
This updates commit 11ab545f3 "install: Set the locale ..."
to be somewhat cleaner, and to explain more in the commit message.

In some environments, either pip itself fails or some packages fail to
install, and setting the locale to en_US.UTF-8 resolves the issue.

We heard reports of this kind of behavior with at least two different
sets of symptoms, with 1.7.0 or its release candidates:
  https://chat.zulip.org/#narrow/stream/general/subject/Trusty.201.2E7.20Upgrade/near/302214
  https://chat.zulip.org/#narrow/stream/production.20help/subject/1.2E6.20to.201.2E7/near/306250

In all reported cases, commit 11ab545f3 or equivalent fixed the issue.

Setting LC_CTYPE is redundant when also setting LC_ALL, because LC_ALL
overrides all `LC_*` environment variables; so skip that.  Also move
the line in `install` to a more appropriate spot, and adjust the
comments.

Greg Price 8f387ba4d4 setup-certbot: Add option to choose verification method.
This allows the installer to continue using this script for the
`standalone` method, while the no-argument form now uses the same
`webroot` method as the renewal cron job, suitable for running
by hand to adopt Certbot after initial install.

Greg Price ae901309fc certbot: Control auto-renew with a zulip.conf setting.
This causes the cron job to run only when a Zulip-managed certbot
install is actually set up.

Inside `install`, zulip.conf doesn't yet exist when we run
setup-certbot, so we write the setting later.  But we also give
setup-certbot the ability to write the setting itself, so that we
can recommend it in instructions for adopting certbot in an
existing Zulip installation.

Tim Abbott 304bd86173 install: Support installing a Zulip server from a Git checkout.
Historically, one has needed to build a release tarball in order to
use/test the Zulip installer, but you could upgrade a Zulip server
from Git.  However, the only reason for that requirement was that we
didn't run `tools/update-prod-static` as part of the install script if
it's required.  A good test for that case is whether we're in a Git
repository, but a better one is to check whether the prod-static
content exists in the tarball paths.

Tim Abbott 2424819749 install: Move upstart checks a bit earlier.
This should make it much more likely that users see this before

since this requires `lsb_release` to be installed.
