RabbitMQ是一个开源的消息代理和队列服务器，通过Erlang编写，用来通过普通协议在完全不同的应用之间共享数据。并且RabbitMQ是基于高级消息队列（AMQP）协议的。
当前以Centos7系统为例，部署RabbitMQ3.7.x，由于RabbitMQ需要Erlang支持，所以这里先安装Erlang，你可以通过epel源来安装（epel提供的版本过旧），也可以通过配置yum源来安装，我这里以yum源来安装。
安装Erlang {#title-0}
1、配置Erlang源
cat > /etc/yum.repos.d/rabbitmq-erlang.repo << EOF [rabbitmq-erlang] name=rabbitmq-erlang baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/22/el/7 gpgcheck=1 gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc repo_gpgcheck=0 enabled=1 EOF
|-------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 | cat > /etc/yum.repos.d/rabbitmq-erlang.repo << EOF [rabbitmq-erlang] name=rabbitmq-erlang baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/22/el/7 gpgcheck=1 gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc repo_gpgcheck=0 enabled=1 EOF |
2、安装erlang和socat
yum install erlang socat -y
|---|-----------------------------| | 1 | yum install erlang socat -y |
3、查看erlang版本
erl -version Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 10.7.2
|-----|-----------------------------------------------------------------------------| | 1 2 | erl -version Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 10.7.2 |
可以直接运行erl命令切换到Erlang shell
erl Erlang/OTP 22 [erts-10.7.2] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe] Eshell V10.7.2 (abort with ^G) 1> 按ctrl+c两次退出
|-----------|----------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 | erl Erlang/OTP 22 [erts-10.7.2] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe] Eshell V10.7.2 (abort with ^G) 1> 按ctrl+c两次退出 |
安装RabbitMQ {#title-1}
1、配置rabbitmq源
cat > /etc/yum.repos.d/rabbitmq.repo << EOF [bintray-rabbitmq-server] name=bintray-rabbitmq-rpm baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/ gpgcheck=0 repo_gpgcheck=0 enabled=1 EOF
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 | cat > /etc/yum.repos.d/rabbitmq.repo << EOF [bintray-rabbitmq-server] name=bintray-rabbitmq-rpm baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/ gpgcheck=0 repo_gpgcheck=0 enabled=1 EOF |
2、安装rabbitmq
yum install rabbitmq-server -y
|---|--------------------------------| | 1 | yum install rabbitmq-server -y |
3、启动RabbitMQ
注意：rabbitmq默认以系统用户rabbitmq身份运行，如果更改节点数据或日志的位置，确保文件权限是rabbitmq（并且还要更新环境变量）
systemctl start rabbitmq-server
|---|---------------------------------| | 1 | systemctl start rabbitmq-server |
4、设置开机自启
systemctl enable rabbitmq-server
|---|----------------------------------| | 1 | systemctl enable rabbitmq-server |
5、启用rabbitmq的web控制台
rabbitmq-plugins enable rabbitmq_management Enabling plugins on node rabbit@whsir6: rabbitmq_management The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch Applying plugin configuration to rabbit@whsir6... The following plugins have been enabled: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch started 3 plugins.
|----------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | rabbitmq-plugins enable rabbitmq_management Enabling plugins on node rabbit@whsir6: rabbitmq_management The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch Applying plugin configuration to rabbit@whsir6... The following plugins have been enabled: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch started 3 plugins. |
6、刷新文件权限
chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
|---|-----------------------------------------------| | 1 | chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/ |
注：rabbitmq默认账号密码为guest，但是guest用户只能通过localhost登录使用，所以我这里建议修改guest用户的密码及新建账号来管理rabbitmq
用户标签 {#title-2}
在该版本的rabbitmq中默认有六种标签设置，默认新建的用户标签为none
administrator（超级管理员）：无需解释，至高权限
monitoring（监控者）：可以查看节点相关信息、内存、集群、统计等情况
policymaker（策略制定者）：可以查看，创建和删除策略和参数，无法查看节点信息
management（普通管理者）：可以查看队列、交换和绑定，无法查看节点信息，也无法对策略进行管理
impersonator（模拟者）：允许应用程序伪造用户ID
none（无）：无法访问管理插件
权限控制 {#title-3}
rabbitmqctl set_permissions [-p <vhost>] <user> <conf> <write> <read>
vhost被授予权限的主机
user被授予权限的用户
conf正则匹配用户在哪些资源具有配置权限
write正则匹配用户在哪些资源具有写权限
read正则匹配用户在哪些资源具有读权限
配置用户 {#title-4}
添加rabbitmqWeb控制台管理用户（wuhao是你要添加的用户名，thisispw是该用户的密码）
rabbitmqctl add_user wuhao thisispw
|---|-------------------------------------| | 1 | rabbitmqctl add_user wuhao thisispw |
查看当前用户列表
rabbitmqctl list_users
|---|------------------------| | 1 | rabbitmqctl list_users |
用户标签分配，我这里为了演示，将administrator分配给用户wuhao
rabbitmqctl set_user_tags wuhao administrator
|---|-----------------------------------------------| | 1 | rabbitmqctl set_user_tags wuhao administrator |
设置wuhao用户在主机所有资源上可配置、可写、可读的权限
rabbitmqctl set_permissions -p / wuhao ".*" ".*" ".*"
|---|----------------------------------------------------------| | 1 | rabbitmqctl set_permissions -p / wuhao ".*" ".*" ".*" |
访问http://IP:15672/，用户wuhao，密码thisispw，登录RabbitMQ
