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 xmlto
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：
[[email protected] rabbitmq]# tar -xzvf otp_src_18.3.tar.gz [[email protected] rabbitmq]# cd otp_src_18.3/
配置安装路径编译代码：
[[email protected] otp_src_18.3]# ./configure --prefix=/opt/erlang
执行编译结果：
[[email protected] otp_src_18.3]# make && make install
完成后进入/opt/erlang查看执行结果
[[email protected] rabbitmq]# cd /opt/erlang/ [[email protected] 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>
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=$PATH:/opt/erlang/bin
source /etc/profile使得文件生效
在安装Erlang过程中，可能会遇到以下问题，一般都是因为系统中缺少相应的包引起的，缺少什么包直接yum安装即可。
2.下载安装RabbitMq
[[email protected] rabbitmq]# weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz
解压文件
[[email protected] rabbitmq]# xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz [[email protected] rabbitmq]# tar -xvf rabbitmq-server-generic-unix-3.6.1.tar -C /opt
解压后进入文件夹/opt发现多了个文件夹rabbitmq-server-generic-unix-3.6.1 ，重命名为rabbitmq以便记忆。
然后在配置rabbitmq环境变量,vi /etc/profile文件，增加下面的环境变量:
#set rabbitmq environment export PATH=$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：
[[email protected] rabbitmq]# cd sbin/ [[email protected] sbin]# ./rabbitmq-server -detached
查看服务状态：
[[email protected] sbin]# ./rabbitmqctl status Status of node [email protected] ... [{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}}]
关闭服务：
[[email protected] sbin]# ./rabbitmqctl stop Stopping and halting node [email protected] ...
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

delete_user <UserName>
change_password <UserName> <NewPassword>
list_users
add_vhost <VHostPath>
delete_vhost <VHostPath>
