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 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:

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

  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]# erl
Erlang/OTP [erts-7.3] [source] [-bit] [smp::] [async-threads:] [hipe] [kernel-poll:false] Eshell V7. (abort with ^G)
>

  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..tar.xz
[root@iZ25e3bt9a6Z rabbitmq]# tar -xvf rabbitmq-server-generic-unix-3.6..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:

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

  查看服务状态:

[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl status
Status of node rabbit@iZ25e3bt9a6Z ...
[{pid,},
{running_applications,

{memory,

{connection_readers,},

{connection_channels,},

{total_used,},
{sockets_limit,},
{sockets_used,}]},
{processes,[{limit,},{used,}]},
{run_queue,},
{uptime,},
{kernel,{net_ticktime,}}]

  关闭服务:

[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl stop
Stopping 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

  RabbitMQ服务安装配置

  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。
