在 Centos7 上安装 Rabbitmq 与配置

1 安装 Erlang 依赖

创建文件/etc/yum.repos.d/rabbitmq-erlang.repo

vim /etc/yum.repos.d/rabbitmq-erlang.repo

添加如下内容，参考文档erlang-rpm：

[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://dl.bintray.com/rabbitmq/Keys/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://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

安装 Erlang package:

yum install erlang

2 安装 RabbitMQ

官方文档有两种安装方式，官方建议第一种。那我们就采用第一种 Package Cloud 的方式安装。

详细的信息大家参考： package-cloud：

添加软件源

我们使用 Package Cloud-provided script 进行快速安装。

包云使用自己的GPG密钥标记分发的包。截至2018年底，包云正在进行一个关键的迁移。项目将不再依赖于“主键”，而是使用特定于存储库的签名键。在迁移完成之前，为了向前兼容性，新旧键都必须导入:

# import the new PackageCloud key that will be used starting December 1st, 2018 (GMT)
rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey

# import the old PackageCloud key that will be discontinued on December 1st, 2018 (GMT)
rpm --import https://packagecloud.io/gpg.key

导入两个密钥后，执行脚本：

curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh

sudo bash

执行结果如下：

详细的信息见官方资料： rabbitmq server install：

安装 RabbitMQ

检查安装包：

[hongjunjia@centos-linux ~]$ yum list |grep rabbit
librabbitmq.i686                            0.8.0-2.el7                base     
librabbitmq.x86_64                          0.8.0-2.el7                base     
librabbitmq-devel.i686                      0.8.0-2.el7                base     
librabbitmq-devel.x86_64                    0.8.0-2.el7                base     
librabbitmq-examples.x86_64                 0.8.0-2.el7                base     
rabbitmq-server.noarch                      3.8.5-1.el7                rabbitmq_rabbitmq-server

一切准备就绪之后，开始安装 RabbitMQ：

yum install -y rabbitmq-server

生成本地服务

[hongjunjia@centos-linux ~]$ chkconfig rabbitmq-server on
Note: Forwarding request to 'systemctl enable rabbitmq-server.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to /usr/lib/systemd/system/rabbitmq-server.service.

启动

[hongjunjia@centos-linux ~]$ sudo rabbitmq-server start
[sudo] password for hongjunjia:

查看状态

sudo rabbitmqctl status

Rabbitmq 配置

开启防火墙

切换到root用户打开iptables的配置文件：

vi /etc/sysconfig/iptables

添加 -A INPUT -m state –state NEW -m tcp -p tcp –dport 5672 -j ACCEPT -A INPUT -m state –state NEW -m tcp -p tcp –dport 15672 -j ACCEPT

打开对应该端口

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5672 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 15672 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

通过运行以下命令将RabbitMQ文件的所有权提供给RabbitMQ用户。

chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/

开启web管理控制台插件

[hongjunjia@centos-linux ~]$ sudo rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@centos-linux:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@centos-linux...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

started 3 plugins.

创建rabbitmq账号

[hongjunjia@centos-linux ~]$ sudo rabbitmqctl add_user admin admin
Adding user "admin" ...
[hongjunjia@centos-linux ~]$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
[hongjunjia@centos-linux ~]$ 
[hongjunjia@centos-linux ~]$ sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...

进入开启web管理控制台

在浏览器中输入如下地址即可登录rabbitmq管理控制台系统：

http://rabbitmq-server:15672/

比如我这里是： http://10.211.55.5:15672/

系统有一个默认账号用户名是guest，密码也是guest，但是这个账号只能在 rabbitmq-server 所在主机上的浏览器中登录，在其他主机登录，可以用上面创建的账号登录，即用户名admin，密码是admin。
