基于SMB、NFS 类的共享存储，对持久话文件的锁定作为Master。

 

 

安装RabbitMQ

https://rabbitmq.com/install-rpm.html

本次安装操作系统：CentOS7.9 

安装方式： yum安装

其他系统或版本请参考官方：https://rabbitmq.com/install-rpm.html 配置yum源

配置yum源

# 单机安装RabbitMQ 可以直接通过yum安装
# 这里一定确认自己需要安装的RabbitMQ版本
# 以下是本次安装配置的yum源
# vi /etc/yum.repos.d/rabbitmq.repo

 安装RabbitMQ 

# 如果yum源安装正确，RabbitMQ安装将会非常方便
# RabbitMQ 依赖socat、logrotate、erlang
# 以下命令会自动安装
 yum install erlang rabbitmq-server -y  

# 单机启动
  service rabbitmq-server start

 

集群配置

hosts配置

# RabbitMQ集群需要配置/etc/hosts满足节点直接相互访问
# /etc/hosts 配置如下（最后一列有时可以不要）
192.168.1.101  RabbitMQ01       rabbit@RabbitMQ01
192.168.1.102  RabbitMQ02       rabbit@RabbitMQ02
192.168.1.103  RabbitMQ03       rabbit@RabbitMQ03

 

同步erlang.cookie文件

# 拷贝RabbitMQ01的 /var/lib/rabbitmq/.erlang.cookie 到RabbitMQ02、RabbitMQ03节点
# 注：.erlang.cookie文件的权限应为400，属主rabbitmq
scp /var/lib/rabbitmq/.erlang.cookie 192.168.1.102:/var/lib/rabbitmq/
scp /var/lib/rabbitmq/.erlang.cookie 192.168.1.103:/var/lib/rabbitmq/

 停止服务

# 停止3个节点的服务
# 注：这里不要用service rabbitmq-server stop
rabbitmqctl stop

 启动并加入集群

# 所有节点以detached方式启动
# 启动集群也使用此命令

rabbitmq-server -detached

# 分别在RabbitMQ02、RabbitMQ03执行如下命令加入集群
# 注： 确保/etc/hosts 已经配置

rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@rabbitmq01   
rabbitmqctl start_app
  
# 如果需要移除节点，需要在另外两个节点操作如下
rabbitmqctl forget_cluster_node rabbit@rabbitmq01

 修改集群名称

# 修改集群名称（默认是第一个节点node名称）
rabbitmqctl set_cluster_name rabbitmq_cluster01

• 返回: Setting cluster name to rabbitmq_cluster01 ...

 

查看集群状态

# 查看集群状态
rabbitmqctl cluster_status    

• 返回如下：

Cluster status of node rabbit@RabbitMQ01 ...
Basics

Cluster name: RabbitMQ_cluster01

配置RabbitMQ WEB管理界面

• 在linux上运行，输入 /usr/sbin/rabbitmq-plugins enable rabbitmq_management 启动可视化插件；
• 默认guest用户（密码guest）只能本机(localhost或127.0.0.1)访问，所以需要配置添加一个其他的用户名，对该用户进行授权，才可以用web 访问；
• 在web浏览器中，输入自己的ip地址和端口号访问,如：http://192.168.x.x:15672
• 可以登录查看rabbitmq里的资源信息
• 集群部署需要每个节点都启动管理界面服务，用户只需添加一次；

以下：添加admin用户，对admin用户进行登录授权。

#启动管理界面服务
/usr/sbin/rabbitmq-plugins enable rabbitmq_management
#创建用户admin及密码password
rabbitmqctl add_user admin password
#设置管理员角色权限
rabbitmqctl set_user_tags admin administrator
#授权登陆
rabbitmqctl set_permissions -p / admin '.*' '.*' '.*'
#list 所有用户及权限
rabbitmqctl list_permissions

 

 

添加用户并授权后,就可以用ip的形式进行访问了。
