CentOS7下RabbitMQ服務安裝配置

RabbitMQ是流行的開源訊息佇列系統，是AMQP（Advanced Message Queuing Protocol高階訊息佇列協議）的標準實現，用erlang語言開發。RabbitMQ據說具有良好的效能和時效性，同時還能夠非常好的支援叢集和負載部署，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。由於專案需要，安裝並配置了RabbitMQ，伺服器作業系統是CentOS7。具體步驟如下：

安裝依賴檔案：

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。

然後解壓檔案：

[root@vm_os rabbitmq]# tar -xzvf otp_src_18.3.tar.gz
[root@vm_os rabbitmq]# cd otp_src_18.3/

配置安裝路徑編譯程式碼：

[root@vm_os otp_src_18.3]# ./configure --prefix=/opt/erlang

執行編譯結果：

[root@vm_os otp_src_18.3]# make && make install

完成後進入/opt/erlang檢視執行結果

[root@vm_os rabbitmq]# cd /opt/erlang/
[root@vm_os 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>

當出現以上資訊時表示安裝完成。然後輸入’halt().’退出即可。

然後在配置Erlang環境變數,vi /etc/profile檔案，增加下面的環境變數:

#set erlang environment
export PATH=$PATH:/opt/erlang/bin

source /etc/profile #使得檔案生效

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@vm_os rabbitmq]# weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz

解壓檔案

[root@vm_os rabbitmq]# xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz
[root@vm_os rabbitmq]# tar -xvf rabbitmq-server-generic-unix-3.6.1.tar　　-C /opt

解壓後進入資料夾/opt發現多了個資料夾rabbitmq-server-generic-unix-3.6.1 ，重新命名為rabbitmq以便記憶。

然後在配置rabbitmq環境變數,vi /etc/profile檔案，增加下面的環境變數:

#set rabbitmq environment
export PATH=$PATH:/opt/rabbitmq/sbin

source /etc/profile使得檔案生效

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@vm_os rabbitmq]# cd sbin/
[root@vm_os sbin]# ./rabbitmq-server -detached

檢視服務狀態：

[root@vm_os sbin]# ./rabbitmqctl status

 {kernel,{net_ticktime,60}}]

關閉服務：

[root@vm_os sbin]# ./rabbitmqctl stop
Stopping and halting node rabbit@vm_os ...

4. 配置網頁外掛

首先建立目錄，否則可能報錯：

mkdir /etc/rabbitmq

然後啟用外掛：

./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

預設使用者guest 密碼guest

5. 遠端訪問配置

預設網頁是不允許訪問的，需要增加一個使用者修改一下許可權，程式碼如下：

新增使用者:rabbitmqctl add_user adminwu 123456

新增許可權:rabbitmqctl set_permissions -p "/" adminwu ".*" ".*" ".*"

修改使用者角色:rabbitmqctl set_user_tags adminwu administrator

然後就可以遠端訪問了，然後可直接配置使用者許可權等資訊。
