[root@contoso ~]# systemctl enable rabbitmq-server
[root@contoso ~]# systemctl restart rabbitmq-server
在CentOS-8-x86_64-1905-dvd1.iso镜像系统上安装更高版本的RabbitMQ,
我们依然使用erlang-solutions-1.0-1.noarch.rpm，亲自试过erlang-solutions-2.0-1.noarch.rpm但没有成功
[root@contoso ~]# wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.8.1/rabbitmq-server-3.8.1-1.el8.noarch.rpm
[root@contoso ~]# yum install -y rabbitmq-server-3.8.1-1.el8.noarch.rpm
[root@contoso ~]# systemctl enable rabbitmq-server
[root@contoso ~]# systemctl start rabbitmq-server
[root@contoso ~]# systemctl status rabbitmq-server
首先看看hostname输出，注意是contoso.com而不是contoso，所以服务才无法启动
[root@contoso ~]# hostname
contoso.com
通过以下命令可以进一步证明rabbitmq-server启动过程需要连接主机名contoso,但是contoso的主机名在此系统上没有设置
[root@contoso ~]# rabbitmqctl status
Status of node rabbit@contoso ...
Error: unable to perform an operation on node 'rabbit@contoso'. 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 rabbit@contoso
DIAGNOSTICS
===========
attempted to contact: [rabbit@contoso]
rabbit@contoso:
* unable to connect to epmd (port 4369) on contoso: address (cannot connect to host/port)
Current node details:
* node name: rabbitmqcli66@contoso
* effective user's home directory: /var/lib/rabbitmq
* Erlang cookie hash: p5tKqEzeEvxH0+WQ75PYkA==
我们可以通过设置以下格式的/etc/hosts文件映射格式，自己添加2条本来就不存在的映射关系
contoso 127.0.0.1
contoso 192.168.10.13
其中192.168.10.13是本机真实的IP地址，这样就能解决rabbitmq-server无法启动的问题啦
[root@contoso ~]# cat /etc/hosts
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 contoso contoso.com
192.168.10.13 contoso contoso.com
如果还是发现启动rabbitmq-server服务失败,那么就直接执行reboot指令重新启动系统解决！

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

在CentOS8系统上，默认集成的Python版本就是2.7.15，所以下面与安装Python2.7.15这个版本的步骤全部跳过，我们直接使用
如下方式直接安装get-pip.py
[root@contoso ~]# python -V
Python 2.7.15
[root@contoso ~]# curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
[root@contoso ~]# python get-pip.py
[root@contoso ~]# python -V
Python 2.7.5
1. 安装 gcc
首先确保你已经安装了gcc包在你的系统上，如果你还没有安装gcc,可以使用下面的命令来安装：
[root@contoso ~]# yum install -y gcc openssl-devel bzip2-devel
2. 下载 python 2.7.15
[root@contoso ~]# cd /usr/src
[root@contoso src]# wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz
[root@contoso src]# ls
debug kernels Python-2.7.15.tgz
[root@contoso src]# tar xzf Python-2.7.15.tgz
3. 安装 python 2.7.15
[root@contoso src]# cd Python-2.7.15
[root@contoso Python-2.7.15]# ./configure --enable-optimizations
make altinstall命令用来防止把默认的2.7.5版本可执行程序/usr/bin/python覆盖掉，意思是保留默认版本的python
4. 查看python版本，python-2.7.15和python-2.7.5两个版本都是全局命令
[root@contoso ~]# /usr/bin/python -V
Python 2.7.5
[root@contoso ~]# python -V
Python 2.7.5
[root@contoso ~]# /usr/local/bin/python2.7 -V
Python 2.7.15
[root@contoso ~]# python2.7 -V
Python 2.7.15
警告：不要重写或链接默认版Python二进制可执行程序/usr/bin/python，这可能会损坏系统，因为默认版已经与CentOS系统深度集成啦。
5. 安装python-2.7.15版模块管理工具
PIP是安装和管理python模块的有用工具。让我们安装python版的PIP工具。
[root@contoso Python-2.7.15]# curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
[root@contoso Python-2.7.15]# python2.7 get-pip.py
Alternatively, you can download the version of rabbitmqadmin which corresponds with the management plugin version 3.8.1 from GitHub.
