[操作系统]RabbitMQ服务安装配置


  RabbitMQ是流行的开源消息队列系统,是AMQP(Advanced Message Queuing Protocol高级消息队列协议)的标准实现,用erlang语言开发。RabbitMQ据说具有良好的性能和时效性,同时还能够非常好的支持集群和负载部署,非常适合在较大规模的分布式系统中使用,具体特性还在验证中,待检验。由于项目需要,安装并配置了RabbitMQ,服务器操作系统是CentOS7,服务器是阿里云主机。具体步骤如下:

  安装依赖文件:

  yum install gcc glibc-devel make ncurses-devel openssl-devel

  1.Erlang安装配置

  下载安装包,地址http://www.erlang.org/downloads,我选择的是otp_src_18.3.tar.gz。

  然后解压文件:

[root@iZ25e3bt9a6Z rabbitmq]# tar -xzvf otp_src_18.3.tar.gz[root@iZ25e3bt9a6Z rabbitmq]# cd otp_src_18.3/

  配置安装路径编译代码:

[root@iZ25e3bt9a6Z otp_src_18.3]# ./configure --prefix=/opt/erlang

  执行编译结果:

[root@iZ25e3bt9a6Z otp_src_18.3]# make && make install

  完成后进入/opt/erlang查看执行结果

[root@iZ25e3bt9a6Z rabbitmq]# cd /opt/erlang/[root@iZ25e3bt9a6Z erlang]# erlErlang/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> 

  当出现以上信息时表示安装完成。然后输入’halt().’退出即可。

  然后在配置Erlang环境变量,vi /etc/profile文件,增加下面的环境变量:

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

  source  /etc/profile使得文件生效

  在安装Erlang过程中,可能会遇到以下问题,一般都是因为系统中缺少相应的包引起的,缺少什么包直接yum安装即可。

  2.下载安装RabbitMq

[root@iZ25e3bt9a6Z rabbitmq]# weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz

  解压文件

[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

  解压后进入文件夹/opt发现多了个文件夹rabbitmq-server-generic-unix-3.6.1 ,重命名为rabbitmq以便记忆。

  然后在配置rabbitmq环境变量,vi /etc/profile文件,增加下面的环境变量:

#set rabbitmq environmentexport PATH=$PATH:/opt/rabbitmq/sbin

  source  /etc/profile使得文件生效

  3.RabbitMQ服务启动关闭

  以上就已经完成了RabbitMq的安装,怎么启动服务呢?

  启动服务:

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

  查看服务状态:

[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl statusStatus 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,"","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}}]

  关闭服务:

[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl stopStopping and halting node rabbit@iZ25e3bt9a6Z ...

  4. 配置网页插件

  首先创建目录,否则可能报错:

mkdir /etc/rabbitmq 

  然后启用插件:

./rabbitmq-plugins enable rabbitmq_management 

  配置linux 端口 15672 网页管理  5672 AMQP端口
  然后访问http://localhost:15672即可 

  默认用户guest 密码guest

  

  5. 远程访问配置

  默认网页是不允许访问的,需要增加一个用户修改一下权限,代码如下:

  添加用户:rabbitmqctl add_user hxb hxb

  添加权限:rabbitmqctl set_permissions -p "/" hxb ".*" ".*" ".*"

      修改用户角色rabbitmqctl set_user_tags hxb administrator

  然后就可以远程访问了,然后可直接配置用户权限等信息。

  

  6. rabbitmq常用命令

  change_password <UserName> <NewPassword>
