RabbitMQ环境搭建
erlang和RabbitMQ版本对应关系：https://www.rabbitmq.com/which-erlang.html
erlang环境安装
yum方式安装
- yum源配置
[root@iyeed RabbitMQ]# curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash
- yum安装erlang
[root@iyeed RabbitMQ]# yum install erlang
- 校验erlang安装是否成功
-
- 执行erl命令
[root@iyeed ~]# erl
Erlang/OTP 23 [erts-11.1.8] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]
Eshell V11.1.8 (abort with ^G)
1>
上面是输入erl命令后显示的信息。
erlErlang/OPT 23：代表的是erlang版本信息，对应的erlang和RabbitMQ对照表中，查找对应的RabbitMQ安装即可
-
- erlang输出消息
1> io:format("hello, world!~n").
hello, world!
ok
2>
-
- 退出erl命令行
2> halt().
完整操作过程如下：
[root@iyeed ~]# erl
Erlang/OTP 23 [erts-11.1.8] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]
Eshell V11.1.8 (abort with ^G)
1> io:format("hello, world!~n").
hello, world!
ok
2> halt().
RabbitMQ安装
导入key
[root@iyeed RabbitMQ]# rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
[root@iyeed RabbitMQ]# rpm --import https://packagecloud.io/gpg.key
以上执行后，没有任何消息反馈，表明导入key成功
安装RabbitMQ的前置配置
[root@iyeed RabbitMQ]# curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash
下载RabbitMQ
[root@iyeed RabbitMQ]# wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.14/rabbitmq-server-3.8.14-1.el7.noarch.rpm
安装RabbitMQ
[root@iyeed RabbitMQ]# rpm -ivh rabbitmq-server-3.8.14-1.el7.noarch.rpm
warning: rabbitmq-server-3.8.14-1.el7.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
socat is needed by rabbitmq-server-3.8.14-1.el7.noarch
此处安装时产生了一些问题，原因是缺少key，只需要导入key和安装socat即可
- 导入key
[root@iyeed RabbitMQ]# rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
如执行如下命令后，没有任何输出，则表明导入key成功
- 安装socat
[root@iyeed RabbitMQ]# yum -y install epel-release
[root@iyeed RabbitMQ]# yum -y install socat
- 再次执行rabbitmq的安装命令即可
[root@iyeed RabbitMQ]# rpm -ivh rabbitmq-server-3.8.14-1.el7.noarch.rpm

启动 可视化插件 方便管理 rabbitMQ
[root@iyeed RabbitMQ]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@iyeed:
rabbitmq_management
The following plugins have been configured:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch

The following plugins have been enabled:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
set 3 plugins.
Offline change; changes will take effect at broker restart.
启动RabbitMQ
[root@iyeed RabbitMQ]# systemctl start rabbitmq-server
访问控制台页面
输入http：//（服务器地址）：15672（本示例：http://192.168.0.31:15672/），此时会出现如下UI画面
如果没有出现 请检查防火墙 配置 确认是否开启端口5672和15672，如果没有开启 则无法访问
用户登录和vhost配置
账号密码默认是guest，此时登录会：
RabbitMQ3.3以后，guest账号只能在本机登录，可以通过配置修改，但是太麻烦，此处就创建一个新的账号：
创建admin用户
如创建用户名为admin，密码为admin123的用户
[root@iyeed ~]# rabbitmqctl add_user admin admin123
Adding user "admin" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.
设置admin为超级管理员
[root@iyeed ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
授权admin远程访问
[root@iyeed ~]# rabbitmqctl set_permissions -p / admin "." "." ".*"
Setting permissions for user "admin" in vhost "/" ...
创建完成后，重启RabbitMQ
[root@iyeed ~]# systemctl restart rabbitmq-server
此时就完成 rabbitMQ 的安装了 用户的添加 和 权限的配置 也可以在 ui界面中完成
