RabbitMQ高可用集群安装部署文档
架构图
1)RabbitMQ集群元数据的同步
RabbitMQ集群会始终同步四种类型的内部元数据(类似索引):
a.队列元数据:队列名称和它的属性;
b.交换器元数据:交换器名称、类型和属性;
c.绑定元数据:一张简单的表格展示了如何将消息路由到队列;
d.vhost元数据:为vhost内的队列、交换器和绑定提供命名空间和安全属性;
2)集群配置方式
cluster:不支持跨网段,用于同一个网段内的局域网;可以随意的动态增加或者减少;节点之间需要运行相同版本的 RabbitMQ 和 Erlang。
节点类型
RAM node:内存节点将所有的队列、交换机、绑定、用户、权限和 vhost 的元数据定义存储在内存中,好处是可以使得像交换机和队列声明等操作更加的快速。
Disk node:将元数据存储在磁盘中,单节点系统只允许磁盘类型的节点,防止重启 RabbitMQ 的时候,丢失系统的配置信息。
解决方案:设置两个磁盘节点,至少有一个是可用的,可以保存元数据的更改。
Erlang Cookie
erlang Cookie 是保证不同节点可以相互通信的密钥,要保证集群中的不同节点相互通信必须共享相同的 Erlang Cookie
3)搭建RabbitMQ集群所需要安装的组件
a.Jdk 1.8
b.Erlang运行时环境
c.RabbitMq的Server组件
1、安装yum源文件
# rpm -Uvh https://download.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
2、安装Erlang
# yum -y install erlang
3、配置java环境 /etc/profile
JAVA_HOME=/usr/local/java/jdk1.8.0_151
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
4、安装配置rabbitmq
# tar -xf rabbitmq-server-generic-unix-3.6.15.tar -C /usr/local/
# mv /usr/local/rabbitmq_server-3.6.15/ /usr/local/rabbitmq
5、配置RabbitMQ环境变量/etc/profile
RABBITMQ_HOME=/usr/local/rabbitmq
PATH=$PATH:$ERL_HOME/bin:/usr/local/rabbitmq/sbin
# source /etc/profile
6、修改主机配置文件/etc/hosts
192.168.2.208 rabbitmq-node1
192.168.2.41 rabbitmq-node2
192.168.2.40 rabbitmq-node3
各个主机修改配置文件保持一致
# /root/.erlang.cookie
7、后台启动rabbitmq
# /usr/local/rabbitmq/sbin/rabbitmq-server -detached
添加用户
# rabbitmqctl add_user admin admin
给用户授权
# rabbitmqctl set_user_tags admin administrator
# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
启用插件,可以使用rabbitmq管理界面
# rabbitmq-plugins enable rabbitmq_management
查看用户列表
# rabbitmqctl list_users
查看节点状态
# rabbitmqctl status
查看集群状态
# rabbitmqctl cluster_status
查看插件
# rabbitmq-plugins list
添加防火墙规则/etc/sysconfig/iptables
-A
INPUT -m state --state NEW -m tcp -p tcp --dport 27017 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 28017 -j ACCEPT
-A
INPUT -m state --state NEW -m tcp -p tcp --dport 15672 -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 25672 -j ACCEPT
8、添加集群node节点,从节点执行(目前配置2个节点)
# rabbitmqctl stop_app
# rabbitmqctl join_cluster --ram rabbit@rabbitmq-node2
或者
# rabbitmqctl join_cluster rabbit@rabbitmq-node2
# rabbitmqctl change_cluster_node_type ram
启动节点
#rabbitmqctl start_app
9、删除集群node 节点删除
1. rabbitmq-server -detached
2. rabbitmqctl stop_app
3. rabbitmqctl reset
4. rabbitmqctl start_app
登陆管理界面查看集群状态http://IP:15672/
设置镜像队列策略
在web界面,登陆后,点击“Admin--Virtual Hosts(页面右侧)”,在打开的页面上的下方的“Add a new virtual host”处增加一个虚拟主机,同时给用户“admin”和“guest”均加上权限
1、
2、
# rabbitmqctl set_policy -p hasystem ha-allqueue "^" '{"ha-mode":"all"}' -n rabbit
"hasystem" vhost名称, "^"匹配所有的队列, ha-allqueue 策略名称为ha-all, '{"ha-mode":"all"}' 策略模式为 all 即复制到所有节点,包含新增节点,则此时镜像队列设置成功.
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:表示在集群中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:进行队列中消息的同步方式,有效值为automatic和manual
priority:可选参数,policy的优先级
注以上集群配置完成
高可用HA配置
Haproxy 负载均衡,keepalived实现健康检查HA服务安装配置
解压文件
# tar -zxf haproxy-1.8.17.tar.gz
查看内核版本
# uname –r
# yum -y install gcc gcc-c++ make
切换到解压目录执行安装
# make TARGET=3100 PREFIX=/usr/local/haproxy
# make install PREFIX=/usr/local/haproxy
创建配置文件相关目录
# mkdir /usr/local/haproxy/conf
# mkdir /var/lib/haproxy/
# touch /usr/local/haproxy/haproxy.cfg
# groupadd haproxy
