RabbitMQ是流行的開源消息隊列系統，是AMQP（Advanced Message Queuing Protocol高級消息隊列協議）的標準實現，用erlang語言開發。RabbitMQ據說具有良好的性能和時效性，同時還能夠非常好的支持集群和負載部署，非常適合在較大規模的分散式系統中使用，具體特性還在驗證中，待檢驗。由於項目需要，安裝並配置了RabbitMQ，伺服器操作系統是CentOS7，伺服器是阿裡雲主機。具體步驟如下：
安裝依賴文件：
yum install gcc glibc-devel make ncurses-devel openssl-devel xmlto
1.Erlang安裝配置
下載安裝包，地址http://www.erlang.org/downloads，我選擇的是otp_src_18.3.tar.gz。
然後解壓文件：
[root@iZ25e3bt9a6Z rabbitmq]# tar -xzvf otp_src_18.3.tar.gz [root@iZ25e3bt9a6Z rabbitmq]# cd otp_src_18.3/
配置安裝路徑編譯代碼：
[root@iZ25e3bt9a6Z otp_src_18.3]# ./configure --prefix=/opt/erlang
執行編譯結果：
[root@iZ25e3bt9a6Z otp_src_18.3]# make && make install
完成後進入/opt/erlang查看執行結果
[root@iZ25e3bt9a6Z rabbitmq]# cd /opt/erlang/ [root@iZ25e3bt9a6Z erlang]# erl Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] Eshell V7.3 (abort with ^G) 1>
當出現以上信息時表示安裝完成。然後輸入’halt().’退出即可。
然後在配置Erlang環境變數,vi /etc/profile文件，增加下麵的環境變數:
#set erlang environment
export PATH=$PATH:/opt/erlang/bin
source /etc/profile使得文件生效
在安裝Erlang過程中，可能會遇到以下問題，一般都是因為系統中缺少相應的包引起的，缺少什麼包直接yum安裝即可。
2.下載安裝RabbitMq
[root@iZ25e3bt9a6Z rabbitmq]# weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz
解壓文件
[root@iZ25e3bt9a6Z rabbitmq]# xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz [root@iZ25e3bt9a6Z rabbitmq]# tar -xvf rabbitmq-server-generic-unix-3.6.1.tar -C /opt
解壓後進入文件夾/opt發現多了個文件夾rabbitmq-server-generic-unix-3.6.1 ，重命名為rabbitmq以便記憶。
然後在配置rabbitmq環境變數,vi /etc/profile文件，增加下麵的環境變數:
#set rabbitmq environment export PATH=$PATH:/opt/rabbitmq/sbin
source /etc/profile使得文件生效
3.RabbitMQ服務啟動關閉
以上就已經完成了RabbitMq的安裝，怎麼啟動服務呢？
啟動服務：
[root@iZ25e3bt9a6Z rabbitmq]# cd sbin/
[root@iZ25e3bt9a6Z sbin]# ./rabbitmq-server -detached
查看服務狀態：
[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl status Status of node rabbit@iZ25e3bt9a6Z ... [{pid,11849}, {running_applications, [{rabbitmq_management,"RabbitMQ Management Console","3.6.1"}, {rabbitmq_management_agent,"RabbitMQ Management Agent","3.6.1"}, {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.6.1"}, {webmachine,"webmachine","1.10.3"}, {amqp_client,"RabbitMQ AMQP Client","3.6.1"}, {mochiweb,"MochiMedia Web Server","2.13.0"}, {syntax_tools,"Syntax tools","1.7"}, {ssl,"Erlang/OTP SSL application","7.3"}, {public_key,"Public key infrastructure","1.1.1"}, {asn1,"The Erlang ASN1 compiler version 4.0.2","4.0.2"}, {crypto,"CRYPTO","3.6.3"}, {compiler,"ERTS CXC 138 10","6.0.3"}, {inets,"INETS CXC 138 49","6.2"}, {rabbit,"RabbitMQ","3.6.1"}, {mnesia,"MNESIA CXC 138 12","4.13.3"}, {rabbit_common,[],"3.6.1"}, {xmerl,"XML parser","1.3.10"}, {os_mon,"CPO CXC 138 46","2.4"}, {ranch,"Socket acceptor pool for TCP protocols.","1.2.1"}, {sasl,"SASL CXC 138 11","2.7"}, {stdlib,"ERTS CXC 138 10","2.8"}, {kernel,"ERTS CXC 138 10","4.2"}]}, {os,{unix,linux}}, {erlang_version, "Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:8:8] [async-threads:64] [hipe] [kernel-poll:true]\n"}, {memory, [{total,64111264}, {connection_readers,0}, {connection_writers,0}, {connection_channels,0}, {connection_other,2808}, {queue_procs,2808}, {queue_slave_procs,0}, {plugins,367288}, {other_proc,19041296}, {mnesia,61720}, {mgmt_db,158696}, {msg_index,47120}, {other_ets,1372440}, {binary,128216}, {code,27368230}, {atom,992409}, {other_system,14568233}]}, {alarms,[]}, {listeners,[{clustering,25672,"::"},{amqp,5672,"::"}]}, {vm_memory_high_watermark,0.4}, {vm_memory_limit,6556241100}, {disk_free_limit,50000000}, {disk_free,37431123968}, {file_descriptors, [{total_limit,65435}, {total_used,2}, {sockets_limit,58889}, {sockets_used,0}]}, {processes,[{limit,1048576},{used,204}]}, {run_queue,0}, {uptime,412681}, {kernel,{net_ticktime,60}}]
關閉服務：
[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl stop
Stopping and halting node rabbit@iZ25e3bt9a6Z ...
4. 配置網頁插件
首先創建目錄，否則可能報錯：
mkdir /etc/rabbitmq
然後啟用插件：
./rabbitmq-plugins enable rabbitmq_management
配置linux 埠 15672 網頁管理 5672 AMQP埠
然後訪問http://localhost:15672即可
預設用戶guest 密碼guest
5. 遠程訪問配置
預設網頁是不允許訪問的，需要增加一個用戶修改一下許可權，代碼如下：
添加用戶:rabbitmqctl add_user hxb hxb
添加許可權:rabbitmqctl set_permissions -p "/" hxb ".*" ".*" ".*"
修改用戶角色rabbitmqctl set_user_tags hxb administrator
然後就可以遠程訪問了，然後可直接配置用戶許可權等信息。
6. rabbitmq常用命令
add_user <UserName> <Password>
delete_user <UserName>
change_password <UserName> <NewPassword>
list_users
add_vhost <VHostPath>
delete_vhost <VHostPath>
