# 简介 #

RabbitMQ是一个开源的遵循AMQP协议实现的基于Erlang语言编写，支持多种客户端语言，用于在分布式系统中存储消息，转发消息，具有高可用，高扩展性，易用性等特征。

## 安装RabbitMQ ##

### 在虚拟机上二进制安装 ###

1.  下载地址：[https://www.rabbitmq.com/download.html][https_www.rabbitmq.com_download.html].
2.  环境准备：Centos7.x+Erlang

> RabiitMQ是采用Erlang语言开发的，所以系统环境必须依赖Erlang环境，第一步就是安装Erlang。  
> 查看eralng和RabbitMQ版本对比：[https://www.rabbitmq.com/which-erlang.html][https_www.rabbitmq.com_which-erlang.html].

1.  安装Erlang环境可参考[https://www.cnblogs.com/jimlau/p/12029985.html][https_www.cnblogs.com_jimlau_p_12029985.html].  
    1.安装类库（按照顺序）
    
        yum -y install gcc-c++
        yum -y install ncurses-devel
        yum -y install openssl-devel
        yum -y install unixODBC-devel
        #有可以不用执行安装
        yum install xz
    
    2.安装Erlang环境
    
        tar xvfz otp_src_18.2.1.tar.gz 
        ./configure 
        make install
    
    3.测试
    
        erl -v
2.  安装RabbitMQ  
    1.通过官网下载RabbitMQ最新rpm包,使用以下命令进行安装
    
        rpm -Uvh rabbitmq-server-3.8.14-1.el7.noarch.rpm
    
    2.若安装报错信息如下：
    
        警告：rabbitmq-server-3.8.14-1.el7.noarch.rpm: 头V4    RSA/SHA256 Signature, 密钥 ID 6026dfca: NOKEY
        错误：依赖检测失败：
        erlang >= 21.3 被 rabbitmq-server-3.8.14-1.el7.noarch 需要
    
    3.若安装出现2的问题使用以下命令安装
    
        rpm -ivh --nodeps rabbitmq-server-3.8.14-1.el7.noarch.rpm
    
    4.安装WEB管理界面插件及执行添加用户授权操作即可。
    
        #添加web管理界面插件
        	rabbitmq-plugins enable rabbitmq_management
        	# 重启RbbitMQ
        	systemctl restart rabbitmq-server
        	# 添加用户名、密码
        	rabbitmqctl add_user admin admin
        	# 给用户添加权限
        	rabbitmqctl set_user_tags admin administrator
3.  启动rabbitMq服务命令
    
        #启动服务
        	systemctl start rabbitmq-server
        	#停止服务
        	systemctl stop rabbitmq-server
        	#重启服务
        	systemctl restart  rabbitmq-server
        	#开机自启动服务
        	systemctl enable rabbitmq-server

至此手动安装RbbitMQ完成。

### docker镜像安装 ###

安装命令

docker run -di --name myrabbit -v /home/rabbitmq/data:/var/lib/rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management

http://192.168.204.110:15672/\#/ 访问即可

## RabbitMQ新增授权账号和密码 ##

RabbitMQ默认只有一个来宾用户guest/guest，这个账号密码只适合本机访问，对于虚拟机及远程使用只能新增。

1.  新增用户

> rabbitmqctl add\_user admin admin

1.  设置用户分配操作权限

> rabbitmqctl set\_user\_tags admin administrator

用户级别：
    1、administrator 可以登陆控制台，查看所有信息，可以对Rabbitmq进行管理。
    2、monitoring 监控者 登陆控制台，查看所有信息
    3、policymaker 策略制定者 登陆控制台，指定策略
    4、managment 普通管理员 登陆控制台
    5、none 不能访问management plugin
    6、management 查看自己相关节点信息

1.  为用户添加资源权限

> rabbitmqctl set\_permissions -p /admin “.*" ".*” “.\*”

1.  小结

rabbitmqctl add_user 账号 密码
    rabbitmqctl set_user_tags 账号 权限角色
    rabbitmqctl change_password 用户名 新密码   ---修改密码
    rabbitmqctl delete_user username ---删除用户
    rabbitmqctl list_users 查看用户清单
    rabbitmqctl.bat set_permissions -p / 用户名".*" ".*" ".*" ----为用户设置administrator角色。
    rabbitmqctl.bat set_permissions -p / root  ".*" ".*" ".*"

## RabbitMQWeb管理界面操作及授权 ##

1.  默认情况下，rabbitmq是没有安装web端的客户端插件，需要重新安装才可以生效

> rabbitmq-plugins enable rabbitmq\_management

1.  安装完毕之后，重启服务即可

> systemctl restart rabbitmq-server  
> 一定要记住，在对应服务器（阿里云，腾讯云等）安全组件中开放15672的端口。

1.  访问地址：http://ip:15672/

## RabbitMQ集群安装（单机伪集群） ##

第一步：停止单机服务

[root@localhost ~]# clear
    [root@localhost ~]# ps -aux|grep rabbitmq
    [root@localhost ~]# systemctl stop rabbitmq
    [root@localhost ~]# systemctl stop rabbitmq-server
    [root@localhost ~]# systemctl status rabbitmq-server

第二步：启动第一个节点主节点

# 启动第一个节点
    [root@localhost ~]# sudo RABBITMQ_NODE_PORT=5672 RABBITMQ_NODENAME=rabbit-node1 rabbitmq-server start &
    [1] 1735
    [root@localhost ~]# Configuring logger redirection

      Config file(s): (none)
    
      Starting broker... completed with 3 plugins.

至此代表第一个节点启动成功  
第三步：启动从节点

# 启动第二个节点
    [root@localhost ~]# sudo RABBITMQ_NODE_PORT=5673 RABBITMQ_SERVER_START_ARGS="-rabbitmq_management listener [{port,15673}]" RABBITMQ_NODENAME=rabbit-node2 rabbitmq-server start &
    [2] 1982
    [root@localhost ~]# sudo: listener：找不到命令
    #sudo 找不到这个命令的解决方式：请参考后面备注

第四步：验证俩个节点是否启动成功

[root@localhost ~]# ps -ef|grep rabbitmq
    root       1735   1415  0 16:56 pts/0    00:00:00 /usr/bin/sudo RABBITMQ_NODE_PORT=5672 RABBITMQ_NODENAME=rabbit-node1 env LD_LIBRARY_PATH=/opt/rh/devtoolset-9/root/usr/lib64:/opt/rh/devtoolset-9/root/usr/lib:/opt/rh/devtoolset-9/root/usr/lib64/dyninst:/opt/rh/devtoolset-9/root/usr/lib/dyninst:/opt/rh/devtoolset-9/root/usr/lib64:/opt/rh/devtoolset-9/root/usr/lib PATH=/opt/rh/devtoolset-9/root/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/src/java/jdk-11.0.5/bin:/usr/local/src/java/jdk-11.0.5/bin:/usr/local/mongodb/mongodb/bin:/root/bin scl enable devtoolset-9  'rabbitmq-server' 'start'

    root       2515   1415  0 17:09 pts/0    00:00:00 grep --color=auto rabbitmq

第五步：将rabbit-node1节点操作为主节点

#停止应用
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node1 stop_app
    Stopping rabbit application on node rabbit-node1@localhost ...
    #目的是清除节点上面的数据，若不清除，无法将节点加入集群
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node1 reset
    Resetting node rabbit-node1@localhost ...
    #启动应用
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node1 start_app
    Starting node rabbit-node1@localhost ...

第六步：将rabbit-node2节点操作为从节点

[root@localhost ~]# sudo rabbitmqctl -n rabbit-node2 stop_app
    Stopping rabbit application on node rabbit-node2@localhost ...
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node2 reset
    Resetting node rabbit-node2@localhost ...
    #将rabbit-node2节点加入到主节点中，@服务器的主机名
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node2 join_cluster rabbit-node1@localhost
    Clustering node rabbit-node2@localhost with rabbit-node1@localhost
    [root@localhost ~]# sudo rabbitmqctl -n rabbit-node2 start_app
    Starting node rabbit-node2@localhost ...

第七步：验证集群状态

[root@localhost ~]# sudo rabbitmqctl cluster_status -n rabbit-node1
    Cluster status of node rabbit-node1@localhost ...
    Basics
    
    Cluster name: rabbit-node1@localhost
    
    Disk Nodes
    
    rabbit-node1@localhost
    rabbit-node2@localhost
    
    Running Nodes
    
    rabbit-node1@localhost
    rabbit-node2@localhost

**第八步：Web监控**

分别为节点一和节点二添加用户权限

rabbitmqctl -n rabbit-node1 add\_user admin admin  
rabbitmqctl -n rabbit-node1 set\_user\_tags admin administrator  
rabbitmqctl -n rabbit-node1 set\_permissions -p / admin “.*" ".*” “.\*”

--------------------

rabbitmqctl -n rabbit-node2 add\_user admin admin  
rabbitmqctl -n rabbit-node2 set\_user\_tags admin administrator  
rabbitmqctl -n rabbit-node2 set\_permissions -p / admin “.*" ".*” “.\*”
