帮帮忙看一眼上面三段有啥不对劲的地方吗。

[wanghao]

我猜可能是你之前 Bootstrap 过，已经创建了数据库，再次 Bootstrap 的时候，设置数据库相关的动作就会出错。你可以先删除下面这些东西：

/var/discourse/shared/standalone/postgres_backup
/var/discourse/shared/standalone/postgres_data
/var/discourse/shared/standalone/postgres_run

删掉以上三个文件夹后，又执行了一次，没太大区别，而且这三个文件夹又出来了：

[wanghao]

那就删除整个 /var/discourse ，重新再 clone 一下，再配置，然后再执行 bootstrap 。你可以先把配置好的 app.yml 复制到一个地方。

[aaa]

我认为我配置的 app.yml 完全没问题。
我是直接拷贝后，什么都没有动过，以最小心的姿态，修改最少的配置。

##
## After making changes to this file, you MUST rebuild for any changes
## to take effect in your live Discourse instance:
##
## /var/discourse/launcher rebuild app
##
## Make sure to obey YAML syntax! You can use this site to help check:
## http://www.yamllint.com/

## this is the all-in-one, standalone Discourse Docker container template

# You may add rate limiting by uncommenting the web.ratelimited template.
# Out of the box it allows 12 reqs a second per ip, and 100 per minute per ip
# This is configurable by amending the params in this file

templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/web.template.yml"
  - "templates/sshd.template.yml"
  - "templates/web.ratelimited.template.yml"

## which TCP/IP ports should this container expose?
expose:
  - "80:80"   # fwd host port 80   to container port 80 (http)
  - "2222:22" # fwd host port 2222 to container port 22 (ssh)

params:
  db_default_text_search_config: "pg_catalog.english"
  ## Set db_shared_buffers to 1/3 of the memory you wish to allocate to postgres
  ## on 1GB install set to 128MB on a 4GB instance you may raise to 1GB
  #db_shared_buffers: "256MB"
  #
  ## Which Git revision should this container use? (default: tests-passed)
  #version: tests-passed

env:
  LANG: en_US.UTF-8
  # DISCOURSE_DEFAULT_LOCALE: en

  ## TODO: How many concurrent web requests are supported?
  ## With 2GB we recommend 3-4 workers, with 1GB only 2
  #UNICORN_WORKERS: 3

  ## TODO: List of comma delimited emails that will be made admin and developer

  ## The CDN address for this Discourse instance (configured to pull)
  #DISCOURSE_CDN_URL: //discourse-cdn.example.com

## These containers are stateless, all data is stored in /shared
volumes:
  - volume:

      guest: /shared
  - volume:

## The docker manager plugin allows you to one-click upgrade Discourse
## http://discourse.example.com/admin/docker
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git

## Remember, this is YAML syntax - you can only have one block with a name
run:
  - exec: echo "Beginning of custom commands"

  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  ## After getting the first signup email, re-comment the line. It only needs to run once.

  ## If you want to configure password login for root, uncomment and change:
  ## Use only one of the following lines:
  #- exec: /usr/sbin/usermod -p 'PASSWORD_HASH' root
  #- exec: /usr/sbin/usermod -p "$(mkpasswd -m sha-256 'RAW_PASSWORD')" root

  ## If you want to authorized additional users, uncomment and change:
  #- exec: ssh-import-id username
  #- exec: ssh-import-id anotherusername

  - exec: echo "End of custom commands"
  - exec: awk -F\# '{print $1;}' ~/.ssh/authorized_keys | awk 'BEGIN { print "Authorized SSH keys for this container:"; } NF>=2 {print $NF;}'

端口号没填是因为 mailgun 没有明示端口号。

[wanghao]

不是配置文件的问题。

删除整个 /var/discourse ，重新再 clone 一下，再配置，然后再执行 bootstrap 。结果还是如此，大体上没有任何改变。

稍等，我用软件为电脑全局翻墙后再试试。

补充：
还是失败了。

我准备在美国 IP 的网络下从头开始，再装一次：
这次，从电脑开机开始（我重启电脑，一切从头开始。）。
路由器也重启换一下 IP。
vagrant 也重新建。

[wanghao]

我也遇到过这个问题，不过忘了是怎么解决的了。没事，可以先放一放。以后我们学了 Docker 再说。

[aaa]

问题是成功过一次。
要是说一次没成功过，或许我会再深度研究后再尝试。
可是现有的思路，我完全可以做到。所以我准备再次梳理一下，然后开工。

[aaa]

首先，我把 centos.box 拷贝到当前目录，然后

vagrant box add centos centos.box 安装

vagrant box list 看列表。返回了 centos (virtualbox, 0)

vagrant init centos 初始化。当前目录生成一个名为 Vagrantfile 的文件。编辑这个文件的 3 个区域，去掉 # 号使其生效：

config.vm.synced_folder "discourse", "/var/discourse"

   config.vm.network "private_network", ip: "192.168.33.10"

   config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
     vb.memory = "1024"
   end

在当前目录新建文件夹 discourse

vagrant up 开机

[aaa]

下面登录 PuTTY

账号 root
密码 vagrant

[aaa]

打开 软件，审视一下刚才配置 Vagrantfile 文件，内存为 1024MB 是否正确无误。

[aaa]

查询一下当前是否翻墙成功。

确定当前未安装 docker 和 git：

[aaa]

正式开始安装 Dcoker：

  --fixed-cidr=""                        IPv4 subnet for fixed IPs (ex: 10.20.0.0/16)
                                           this subnet must be nested in the bridge subnet (which is defined by -b or --bip)
  -G, --group="docker"                   Group to assign the unix socket specified by -H when running in daemon mode
                                           use '' (the empty string) to disable setting of a group
  -g, --graph="/var/lib/docker"          Path to use as the root of the Docker runtime
  -H, --host=[]                          The socket(s) to bind to in daemon mode or connect to in client mode, specified using one or more tcp://host:port, unix:///path/to/socket, fd://* or fd://socketfd.
  --icc=true                             Enable inter-container communication
  --insecure-registry=[]                 Enable insecure communication with specified registries (no certificate verification for HTTPS and enable HTTP fallback) (e.g., localhost:5000 or 10.20.0.0/16)
  --ip=0.0.0.0                           Default IP address to use when binding container ports
  --ip-forward=true                      Enable net.ipv4.ip_forward
  --ip-masq=true                         Enable IP masquerading for bridge's IP range
  --iptables=true                        Enable Docker's addition of iptables rules
  --mtu=0                                Set the containers network MTU
                                           if no value is provided: default to the default route MTU or 1500 if no default route is available
  -p, --pidfile="/var/run/docker.pid"    Path to use for daemon PID file
  --registry-mirror=[]                   Specify a preferred Docker registry mirror

  --selinux-enabled=false                Enable selinux support. SELinux does not presently support the BTRFS storage driver
  --storage-opt=[]                       Set storage driver options
  --tls=false                            Use TLS; implied by tls-verify flags
  --tlscacert="/root/.docker/ca.pem"     Trust only remotes providing a certificate signed by the CA given here
  --tlscert="/root/.docker/cert.pem"     Path to TLS certificate file
  --tlskey="/root/.docker/key.pem"       Path to TLS key file
  --tlsverify=false                      Use TLS and verify the remote (daemon: verify client, client: verify daemon)
  -v, --version=false                    Print version information and quit

接下来我将检测 Git 是否安装成功。

[root@localhost ~]# git
usage: git [--version] [--help] [-C <path>] [-c name=value]
           [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
           [-p|--paginate|--no-pager] [--no-replace-objects] [--bare]
           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
           <command> [<args>]

The most commonly used git commands are:
   add        Add file contents to the index
   bisect     Find by binary search the change that introduced a bug
   branch     List, create, or delete branches
   checkout   Checkout a branch or paths to the working tree
   clone      Clone a repository into a new directory
   commit     Record changes to the repository
   diff       Show changes between commits, commit and working tree, etc
   fetch      Download objects and refs from another repository
   grep       Print lines matching a pattern

   log        Show commit logs
   merge      Join two or more development histories together
   mv         Move or rename a file, a directory, or a symlink
   pull       Fetch from and integrate with another repository or a local branch
   push       Update remote refs along with associated objects
   rebase     Forward-port local commits to the updated upstream head
   reset      Reset current HEAD to the specified state
   rm         Remove files from the working tree and from the index
   show       Show various types of objects
   status     Show the working tree status

'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
[root@localhost ~]#

至此，Git 就安装完成了。

下载 Discourse

新建文件夹的时候提示已存在，我用可视化窗口看了下，这个文件夹的确存在。应该是启动虚拟机时同步的那个文件夹。

[root@localhost ~]# mkdir /var/discourse
mkdir: cannot create directory ‘/var/discourse’: File exists
[root@localhost ~]#

顺便看下本地：

---

[root@localhost ~]# git clone https://github.com/discourse/discourse_docker.git /var/discourse
Cloning into '/var/discourse'...

[root@localhost ~]#

---

[root@localhost ~]# cd /var/discourse
[root@localhost discourse]#

---

现在，我看下本地服务器上是否已经下载好此文件：

本地同步的文件夹也看下：

---

我再看下 /var/discourse/containers 目录下是不是还没有一会儿要拷贝的文件：

---

接下来我将执行拷贝命令拷贝：

[root@localhost discourse]# cp samples/standalone.yml containers/app.yml
[root@localhost discourse]#

---

现在：

---

稍后编辑 app.yml 文件的时候将用 Notepad++ 编辑器：
