首先看看hostname輸出，注意是contoso.com而不是contoso，所以服務才無法啟動
[[email protected] ~]# hostname
contoso.com

通過以下命令可以進一步證明rabbitmq-server啟動過程需要連線主機名contoso,但是contoso的主機名在此係統上沒有設定
[[email protected] ~]# rabbitmqctl status
Status of node [email protected] ...
Error: unable to perform an operation on node '[email protected]'. Please see diagnostics information and suggestions below.

Most common reasons for this are:

 * Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
 * CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
 * Target node is not running

In addition to the diagnostics info below:

 * See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node [email protected]

DIAGNOSTICS
===========

attempted to contact: [[email protected]]

[email protected]:
  * unable to connect to epmd (port 4369) on contoso: address (cannot connect to host/port)


Current node details:
 * node name: [email protected]
 * effective user's home directory: /var/lib/rabbitmq
 * Erlang cookie hash: p5tKqEzeEvxH0+WQ75PYkA==

我們可以通過設定以下格式的/etc/hosts檔案對映格式，自己新增2條本來就不存在的對映關係
contoso 127.0.0.1
contoso 192.168.10.13
其中192.168.10.13是本機真實的IP地址，這樣就能解決rabbitmq-server無法啟動的問題啦

[[email protected] ~]# cat /etc/hosts
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 contoso contoso.com

一個是配置資訊的配置檔案 rabbitmq.config；
注意，這兩個檔案預設是沒有的，如果需要必須自己建立。

rabbitmq-env.conf
這個檔案的位置是確定和不能改變的，位於：/etc/rabbitmq目錄下（這個目錄需要自己建立）。
檔案的內容包括了RabbitMQ的一些環境變數，常用的有：

RabbitMQ Management HTTP API
Introduction

Apart from this help page, all URIs will serve only resources of type application/json, and will require HTTP basic authentication (using the standard RabbitMQ user database). The default user is guest/guest.

Many URIs require the name of a virtual host as part of the path, since names only uniquely identify objects within a virtual host. As the default virtual host is called "/", this will need to be encoded as "%2f".

PUTing a resource creates it. The JSON object you upload must have certain mandatory keys (documented below) and may have optional keys. Other keys are ignored. Missing mandatory keys constitute an error.

Since bindings do not have names or IDs in AMQP we synthesise one based on all its properties. Since predicting this name is hard in the general case, you can also create bindings by POSTing to a factory URI. See the example below.

Many URIs return lists. Such URIs can have the query string parameters sort and sort_reverse added. sort allows you to select a primary field to sort by, and sort_reverse will reverse the sort order if set to true. The sort parameter can contain subfields separated by dots. This allows you to sort by a nested component of the listed items; it does not allow you to sort by more than one field. See the example below.

You can also restrict what information is returned per item with the columns parameter. This is a comma-separated list of subfields separated by dots. See the example below.

Most of the GET queries return many fields per object. See the separate stats documentation.
Examples

A few quick examples for Windows and Unix, using the command line tool curl:

    Get a list of vhosts:

    :: Windows
    C:\> curl -i -u guest:guest http://localhost:15672/api/vhosts
    # Unix
    $ curl -i -u guest:guest http://localhost:15672/api/vhosts
    HTTP/1.1 200 OK
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:00:02 GMT
    Content-Type: application/json
    Content-Length: 30

    [{"name":"/","tracing":false}]

    Get a list of channels, fast publishers first, restricting the info items we get back:

    :: Windows
    C:\> curl -i -u guest:guest "http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate"

    # Unix
    $ curl -i -u guest:guest 'http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate'

    HTTP/1.1 200 OK
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:01:17 GMT
    Content-Type: application/json
    Content-Length: 219
    Cache-Control: no-cache

    [{"message_stats":{"publish_details":{"rate" ... (remainder elided)

    Create a new vhost:

    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
          -XPUT http://localhost:15672/api/vhosts/foo

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
       -XPUT http://localhost:15672/api/vhosts/foo

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:03:00 GMT
    Content-Type: application/json
    Content-Length: 0

    Note: you must specify application/json as the mime type.

    Note: the name of the object is not needed in the JSON object uploaded, since it is in the URI. As a virtual host has no properties apart from its name, this means you do not need to specify a body at all!
    Create a new exchange in the default virtual host:

    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
           -XPUT -d"{""type"":""direct"",""durable"":true}" ^
           http://localhost:15672/api/exchanges/%2f/my-new-exchange

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
        -XPUT -d'{"type":"direct","durable":true}' \
        http://localhost:15672/api/exchanges/%2f/my-new-exchange

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:04:00 GMT
    Content-Type: application/json
    Content-Length: 0

    Note: we never return a body in response to a PUT or DELETE, unless it fails.
    And delete it again:

    :: Windows
    C:\> curl -i -u guest:guest -H "content-type:application/json" ^
           -XDELETE http://localhost:15672/api/exchanges/%2f/my-new-exchange

    # Unix
    $ curl -i -u guest:guest -H "content-type:application/json" \
        -XDELETE http://localhost:15672/api/exchanges/%2f/my-new-exchange

    HTTP/1.1 204 No Content
    Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
    Date: Mon, 16 Sep 2013 12:05:30 GMT
    Content-Type: application/json
    Content-Length: 0

[[email protected] ~]# python -V
Python 2.7.5

1. 安裝 gcc
首先確保你已經安裝了gcc包在你的系統上，如果你還沒有安裝gcc,可以使用下面的命令來安裝：
[[email protected] ~]# yum install -y gcc openssl-devel bzip2-devel

2. 下載 python 2.7.15
[[email protected] ~]# cd /usr/src
[[email protected] src]# wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz
[[email protected] src]# ls
debug  kernels  Python-2.7.15.tgz
[[email protected] src]# tar xzf Python-2.7.15.tgz

3. 安裝 python 2.7.15
[[email protected] src]# cd Python-2.7.15
[[email protected] Python-2.7.15]# ./configure --enable-optimizations
make altinstall命令用來防止把預設的2.7.5版本可執行程式/usr/bin/python覆蓋掉，意思是保留預設版本的python

4. 檢視python版本，python-2.7.15和python-2.7.5兩個版本都是全域性命令
[[email protected] ~]# /usr/bin/python -V
Python 2.7.5
[[email protected] ~]# python -V
Python 2.7.5
[[email protected] ~]# /usr/local/bin/python2.7 -V
Python 2.7.15
[[email protected] ~]# python2.7 -V
Python 2.7.15

警告：不要重寫或連結預設版Python二進位制可執行程式/usr/bin/python，這可能會損壞系統，因為預設版已經與CentOS系統深度整合啦。

5. 安裝python-2.7.15版模組管理工具
PIP是安裝和管理python模組的有用工具。讓我們安裝python版的PIP工具。

[[email protected] Python-2.7.15]# curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
[[email protected] Python-2.7.15]# python2.7 get-pip.py
