在切诺基反向代理后面运行 buildbot

Question

我正在尝试在 cherokee 反向代理后面运行我的 buildbot 主服务器，并将 buildbot 实例作为循环反向代理布局中 cherokee 的信息源。

这是 buildbot master.cfg 配置文件：-

# -*- python -*-
# ex: set syntax=python:

# This is a sample buildmaster config file. It must be installed as
# 'master.cfg' in your buildmaster's base directory.

# This is the dictionary that the buildmaster pays attention to. We also use
# a shorter alias to save typing.
c = BuildmasterConfig = {}

####### BUILDSLAVES

# The 'slaves' list defines the set of recognized buildslaves. Each element is
# a BuildSlave object, specifying a unique slave name and password.  The same
# slave name and password must be configured on the slave.
from buildbot.buildslave import BuildSlave
c['slaves'] = [BuildSlave("example-slave", "pass")]

# 'slavePortnum' defines the TCP port to listen on for connections from slaves.
# This must match the value configured into the buildslaves (with their
# --master option)
c['slavePortnum'] = 9989

####### CHANGESOURCES

# the 'change_source' setting tells the buildmaster how it should find out
# about source code changes.  Here we point to the buildbot clone of pyflakes.

from buildbot.changes.gitpoller import GitPoller
c['change_source'] = []
c['change_source'].append(GitPoller(
        'git://github.com/buildbot/pyflakes.git',
        workdir='gitpoller-workdir', branch='master',
        pollinterval=300))

####### SCHEDULERS

# Configure the Schedulers, which decide how to react to incoming changes.  In this
# case, just kick off a 'runtests' build

from buildbot.schedulers.basic import SingleBranchScheduler
from buildbot.schedulers.forcesched import ForceScheduler
from buildbot.changes import filter
c['schedulers'] = []
c['schedulers'].append(SingleBranchScheduler(
                            name="all",
                            change_filter=filter.ChangeFilter(branch='master'),
                            treeStableTimer=None,
                            builderNames=["runtests"]))
c['schedulers'].append(ForceScheduler(
                            name="force",
                            builderNames=["runtests"]))

####### BUILDERS

# The 'builders' list defines the Builders, which tell Buildbot how to perform a build:
# what steps, and which slaves can execute them.  Note that any particular build will
# only take place on one slave.

from buildbot.process.factory import BuildFactory
from buildbot.steps.source import Git
from buildbot.steps.shell import ShellCommand

factory = BuildFactory()
# check out the source
factory.addStep(Git(repourl='git://github.com/buildbot/pyflakes.git', mode='copy'))
# run the tests (note that this will require that 'trial' is installed)
factory.addStep(ShellCommand(command=["trial", "pyflakes"]))

from buildbot.config import BuilderConfig

c['builders'] = []
c['builders'].append(
    BuilderConfig(name="runtests",
      slavenames=["example-slave"],
      factory=factory))

####### STATUS TARGETS

# 'status' is a list of Status Targets. The results of each build will be
# pushed to these targets. buildbot/status/*.py has a variety to choose from,
# including web pages, email senders, and IRC bots.

c['status'] = []

from buildbot.status import html
from buildbot.status.web import authz, auth

authz_cfg=authz.Authz(
    # change any of these to True to enable; see the manual for more
    # options
    auth=auth.BasicAuth([("pyflakes","pyflakes")]),
    gracefulShutdown = False,
    forceBuild = 'auth', # use this to test your slave once it is set up
    forceAllBuilds = False,
    pingBuilder = False,
    stopBuild = False,
    stopAllBuilds = False,
    cancelPendingBuild = False,
)
c['status'].append(html.WebStatus(http_port=8010, authz=authz_cfg))

####### PROJECT IDENTITY

# the 'title' string will appear at the top of this buildbot
# installation's html.WebStatus home page (linked to the
# 'titleURL') and is embedded in the title of the waterfall HTML page.

c['title'] = "Pyflakes"
c['titleURL'] = "http://divmod.org/trac/wiki/DivmodPyflakes"

# the 'buildbotURL' string should point to the location where the buildbot's
# internal web server (usually the html.WebStatus page) is visible. This
# typically uses the port number set in the Waterfall 'status' entry, but
# with an externally-visible host name which the buildbot cannot figure out
# without some help.

c['buildbotURL'] = "http://localhost:8010/"

####### DB URL

c['db'] = {
    # This specifies what database buildbot uses to store its state.  You can leave
    # this at its default for all but the largest installations.
    'db_url' : "sqlite:///state.sqlite",
}
    # change any of these to True to enable; see the manual for more
    # options
    auth=auth.BasicAuth([("pyflakes","pyflakes")]),

这是切诺基配置：-

不幸的是，当我转到我的网页网址时，我得到了502 Bad gateway，但另一方面，我知道我的 buildbot 主服务器实例工作正常，因为转到相同的网页网址并在网页网址后面附加 :8010给了我“欢迎来到 Buildbot ...”页面。

Answer 1

您的代理与 buildbot 是否在同一台机器上？如果没有，您需要调整 cherokee 中的 URL，以指向运行 buildbot 的机器（localhost 指向运行 cherokee 的机器）。

在任何情况下，c['buildbotURL'] 都应更改为指向 buildbot 可用的公共 URL（即 cherokee 公开的内容，而不是被代理的 URL）。
