1.2、Linux CE 版 (centos7 )

系统:CentOS Linux release 7.4.1708
地址:192.168.2.113

1.2.1 安装Erlang环境
http://www.rabbitmq.com/install-rpm.html
https://www.erlang-solutions.com/resources/download.html

> wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm

1.2.4 卸载

> yum erase rabbitmq-server -y
> rm -rf /var/lib/rabbitmq/
> rm -rf /etc/rabbitmq

二、RabbitMQ 集群

https://www.rabbitmq.com/clustering.html

系统:CentOS Linux release 7.4.1708
192.168.2.113 hostname host01 存储方式是Disk 硬盘
192.168.2.114 hostname host02 存储方式是RAM 内存
192.168.2.115 hostname host03 存储方式是Disk 硬盘

2.1、安装

三台服务器同时安装Linux CE版,同单机方式

2.2、配置

2.2.1 设置hosts

> vi /etc/hosts

192.168.2.113 host01
192.168.2.114 host02
192.168.2.115 host03

如下图:
RabbitMQ-linux-hosts.png

2.2.2 统一使用erlang.cookie

> scp -r /var/lib/rabbitmq/.erlang.cookie  rabbitmq02:/var/lib/rabbitmq/.erlang.cookie
> scp -r /var/lib/rabbitmq/.erlang.cookie  rabbitmq03:/var/lib/rabbitmq/.erlang.cookie

2.2.3 重启三个rabbitmq-server

> systemctl restart rabbitmq-server

查看日志:

RabbitMQ-linux-logs.png

2.2.4 创建集群

将rabbit@host02和rabbit@host03节点加入rabbit@host01

#在host02执行:
> rabbitmqctl stop_app
> rabbitmqctl join_cluster --ram rabbit@host01
> rabbitmqctl start app

RabbitMQ-linux-host02.png

#在host03执行:
> rabbitmqctl stop_app
> rabbitmqctl join_cluster --ram rabbit@host01
> rabbitmqctl start app

RabbitMQ-linux-host03.png

#然后在host01上查看集群:
> rabbitmqctl cluster_status

RabbitMQ-linux-cluster-status.png

#设置镜像策略:
> rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'

2.2.4 设置管理员

# 在host01上面设置管理员:
> sudo rabbitmqctl add_user root 123456
> sudo rabbitmqctl set_user_tags root administrator
> sudo rabbitmqctl set_permissions -p / root ".*" ".*" ".*"

打开一下任意地址:
http://192.168.2.113:15672
http://192.168.2.114:15672
http://192.168.2.115:15672

都可以登录

2.3、常见命令

2.3.1 服务启动关闭
启动:systemctl start rabbitmq-server
重启:systemctl restart rabbitmq-server
关闭:systemctl stop rabbitmq-server
2.3.2 集群配置相关命令
停止节点:rabbitmqctl stop_app 
重置节点:rabbitmqctl reset 
将当前节点加入集群:rabbitmqctl join_cluster {rabbit_node_name}
集群状态:rabbitmqctl cluster_status 
从当前节点剔除节点:rabbitmqctl forget_cluster_node {rabbit_node_name}

2.3.3 插件管理
查看插件列表: rabbitmq-plugins list
开启某个插件: rabbitmq-plugins enable {插件名} 
关闭某个插件: rabbitmq-plugins disable {插件名}

2.3.4 用户管理


添加用户:rabbitmqctl add_user {username} {password} 
删除用户:rabbitmqctl delete_user {username} 
修改密码:rabbitmqctl change_password {username} {newpassword} 
设置用户角色:rabbitmqctl set_user_tags {username} {tag} 
tag可以为administrator, monitoring, management 
举例: 
rabbitmqctl add_user root 123456
rabbitmqctl set_user_tags root administrator 
rabbitmqctl list_users

2.3.5 权限管理


权限设置:rabbitmqctl set_permissions [-p vhostpath] {user} {conf} {write} {read} 
    conf:一个正则表达式match哪些配置资源能够被该用户访问。 
    write:一个正则表达式match哪些配置资源能够被该用户读。 
    read:一个正则表达式match哪些配置资源能够被该用户访问。
查看(指定vhost)所有用户的权限信息:rabbitmqctl list_permissions [-p vhostPath] 
查看指定用户的权限信息:rabbitmqctl list_user_permissions {username} 
清除用户的权限信息: rabbitmqctl clear_permissions [-p vhostPath] {username}
举例: 
rabbitmqctl set_permissions -p / root “.*” “.*” “.*”

2.3.6 获取服务器状态信息

服务器状态:rabbitmqctl status 
队列信息: rabbitmqctl list_queues [-p vhostpath] [queueinfoitem …] 
queueinfoitem可以为: name, durable, auto_delete, arguments, messages_ready, messages_unacknowled, messages, consumers, memory.
Exchange信息: rabbitmqctl list_exchanges [-p vhostpath] [exchangeinfoitem …] 
exchangeinfoitem有:name, type, durable, auto_delete, internal, arguments.
Binding信息:rabbitmqctl list_bindings [-p vhostpath] [bindinginfoitem …] 
bindinginfoitem有:source_name, source_kind, destination_name, destination_kind, routing_key, arguments.等
connection信息:rabbitmqctl list_connections [connectioninfoitem …] 
connectioninfoitem有:recv_oct,recv_cnt,send_oct,send_cnt,send_pend等。
channel信息:rabbitmqctl list_channels [channelinfoitem …] 
channelinfoitem有:consumer_count,messages_unacknowledged,messages_uncommitted,acks_uncommitted,messages_unconfirmed,prefetch_count,client_flow_blocked
举例: 
rabbitmqctl list_queues name messages_ready pid slave_pids

2.3.7 更改节点类型

rabbitmqctl stop_app 
rabbitmqctl change_cluster_node_type disc 
或 
rabbitmqctl change_cluster_node_type ram 
rabbitmqctl start_app

2.3.8 vhost管理

添加vhost: rabbitmqctl add vhost {name} 
删除vhost: rabbitmqctl delete vhost {name}
2.3.9 镜像队列的设置

镜像队列的配置通过添加policy完成,policy添加的命令为: 
rabbitmqctl set_policy [-p Vhost] Name Pattern Definition [Priority] 
-p Vhost: 可选参数,针对指定vhost下的queue进行设置 
Name: policy的名称 
Pattern: queue的匹配模式(正则表达式) 
Definition: 镜像定义,包括三个部分 ha-mode,ha-params,ha-sync-mode 
    ha-mode: 指明镜像队列的模式,有效值为 all/exactly/nodes 
        all表示在集群所有的节点上进行镜像 
        exactly表示在指定个数的节点上进行镜像,节点的个数由ha-params指定 
        nodes表示在指定的节点上进行镜像,节点名称通过ha-params指定 
    ha-params: ha-mode模式需要用到的参数 
    ha-sync-mode: 镜像队列中消息的同步方式,有效值为automatic,manually 
Priority: 可选参数, policy的优先级
例如,对队列名称以hello开头的所有队列进行镜像,并在集群的两个节点上完成镜像,policy的设置命令为: 
rabbitmqctl set_policy hello-ha “^hello” ‘{“ha-mode”:”exactly”,”ha-params”:2,”ha-sync-mode”:”automatic”}’
