RabbitMQ服務安裝配置

silent發表於2016-03-28

  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,伺服器是阿里雲主機。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@iZ25e3bt9a6Z rabbitmq]# tar -xzvf otp_src_18.3.tar.gz
[root@iZ25e3bt9a6Z rabbitmq]# cd otp_src_18.3/

  配置安裝路徑編譯程式碼:

[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檢視執行結果

[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@iZ25e3bt9a6Z 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@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@iZ25e3bt9a6Z rabbitmq]# cd sbin/
[root@iZ25e3bt9a6Z sbin]# ./rabbitmq-server -detached

  檢視服務狀態:

[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl status

      {sasl,"SASL  CXC 138 11","2.7"},
      {stdlib,"ERTS  CXC 138 10","2.8"},
      {kernel,"ERTS  CXC 138 10","4.2"}]},
 {os,{unix,linux}},

      {connection_channels,0},
      {connection_other,2808},
      {queue_procs,2808},

      {msg_index,47120},
      {other_ets,1372440},
      {binary,128216},
      {code,27368230},

 {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 hxb hxb

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

      修改使用者角色rabbitmqctl set_user_tags hxb 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。

  

  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>

  list_vhostsset_permissions   [-p <VHostPath>] <UserName> <Regexp> <Regexp> <Regexp>

  clear_permissions [-p <VHostPath>] <UserName>

  list_permissions  [-p <VHostPath>]

  list_user_permissions <UserName>

  list_queues    [-p <VHostPath>] [<QueueInfoItem> ...]

  list_exchanges [-p <VHostPath>] [<ExchangeInfoItem> ...]

  list_bindings  [-p <VHostPath>]

  list_connections [<ConnectionInfoItem> ...]
