5.4、RabbitMQ安装部署

5.4.1、简介

RabbitMQ是一款知名的开源消息列队系统，为企业提供消息的发布、订阅、点对点传输等消息服务。

RabbitMQ在企业开发中十分常见，课程为大家演示快速搭建RabbitMQ环境。

5.4.2、安装

RabbitMQ在yum仓库中的版本比较老，所以我们需要手动构建yum仓库。

1、准备yum仓库
① 准备gpgkey密钥

# root执行
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
rpm --import https://packagecloud.io/rabbitmq/erlang/gpgkey
rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey

② 准备仓库文件

# root执行
vim /etc/yum.repos.d/rabbitmq.repo

③ 在rabbitmq.repo中填入如下内容

##
## Zero dependency Erlang
##

[rabbitmq_erlang]
name=rabbitmq_erlang
baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[rabbitmq_erlang-source]
name=rabbitmq_erlang-source
baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

##
## RabbitMQ server
##

[rabbitmq_server]
name=rabbitmq_server
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/$basearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[rabbitmq_server-source]
name=rabbitmq_server-source
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

2、安装RabbitMQ

# root执行
yum -y install erlang rabbitmq-server

3、启动

# root执行
# 使用systemctl管控，服务名：rabbitmq-server
systemctl enable rabbitmq-server         # 开机自启
systemctl disable rabbitmq-server        # 关闭开机自启
systemctl start rabbitmq-server          # 启动
systemctl stop rabbitmq-server           # 关闭
systemctl status rabbitmq-server         # 查看状态

4、放行防火墙，RabbitMQ使用5672、15672、25672的3个端口

# 以下操作2选1即可
# 方式1：关闭防火墙
systemctl stop firewalld     #关闭防火墙
systemctl disable firewalld  #停止防火墙开机自启

# 方式2：放行5672、15672、25672端口的外部访问
firewall-cmd --add-port=5672/tcp --permanent		# 放行tcp规则下的5672端口，永久生效
firewall-cmd --add-port=15672/tcp --permanent		# 放行tcp规则下的15672端口，永久生效
firewall-cmd --add-port=25672/tcp --permanent		# 放行tcp规则下的25672端口，永久生效
firewall-cmd --reload								# 重新加载防火墙规则

5、启动RabbitMQ的WEB管理控制台

rabbitmq-plugins enable rabbitmq_management

6、添加admin用户，并赋予权限

rabbitmqctl add_user admin 'admin'     # rabbitmqctl add_user admin 'admin用户的密码'
rabbitmqctl set_permissions -p "/" "admin" ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator

7、浏览器打开管理控制台
