一、安装部署

1. 配置和拷贝解析文件

cs 复制代码

[root@rabbitmq01 ~]# vim /etc/hosts
[root@rabbitmq01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.159.129 rabbitmq01
192.168.159.230 rabbitmq02
192.168.159.239 rabbitmq03
[root@rabbitmq01 ~]# scp /etc/hosts rabbitmq02:/etc/hosts

[root@rabbitmq01 ~]# scp /etc/hosts rabbitmq03:/etc/hosts

2. 配置官方YUM源

cs 复制代码

[root@rabbitmq01 ~]# vim  /etc/yum.repos.d/rabbitmq.repo 
# In /etc/yum.repos.d/rabbitmq.repo

##
## Zero dependency Erlang

metadata_expire=300

3. 安装和启动

cs 复制代码

[root@rabbitmq01 ~]# yum clean all

[root@rabbitmq01 ~]# yum install rabbitmq-server -y

# 设置启动并开机自启
[root@rabbitmq01 ~]# systemctl start rabbitmq-server.service
[root@rabbitmq01 ~]# systemctl enable rabbitmq-server.service

二、账号配置

cs 复制代码

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl add_user  user_monitoring  passwd_monitor
rabbitmqctl set_user_tags user_monitoring monitoring
rabbitmqctl set_user_tags user_monitoring management
rabbitmqctl list_users
rabbitmq-plugins enable rabbitmq_management
systemctl restart rabbitmq-server

浏览器访问：

可选：新建用户并配置权限【部署集群过程中不是必须的】

cs 复制代码

[root@rabbitmq01 ~]# rabbitmqctl add_user superrd superrd
Adding user "superrd" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.
[root@rabbitmq01 ~]# rabbitmqctl  set_permissions -p /  admin '.*' '.*' '.*'  
Setting permissions for user "admin" in vhost "/" ...
[root@rabbitmq01 ~]# rabbitmqctl set_permissions -p / superrd ".*" ".*" ".*"
Setting permissions for user "superrd" in vhost "/" ...
[root@rabbitmq01 ~]#  rabbitmqctl list_user_permissions admin
Listing permissions for user "admin" ...
vhost	configure	write	read
/	.*	.*	.*
[root@rabbitmq01 ~]#  rabbitmqctl list_permissions -p /
Listing permissions for vhost "/" ...
user	configure	write	read
admin	.*	.*	.*
guest	.*	.*	.*
superrd	.*	.*	.*

三、搭建 rabbitmq 的一般模式集群

cs 复制代码

[root@rabbitmq01 ~]# chmod 600 /var/lib/rabbitmq/.erlang.cookie

[root@rabbitmq01 ~]# scp /var/lib/rabbitmq/.erlang.cookie 

[root@rabbitmq01 ~]# scp /var/lib/rabbitmq/.erlang.cookie 

# 查看服务器单节点状态
[root@rabbitmq01 ~]#  rabbitmqctl status

# 查看集群状态
[root@rabbitmq01 ~]# rabbitmqctl cluster_status

2. Rabbitmq 集群添加节点

rabbitmq01重启，rabbitmq02，rabbitmq03执行以下服务

cs 复制代码

# rabbitmq01上重启rabbitmq
[root@rabbitmq01 ~]# systemctl restart rabbitmq-server.service

# rabbitmq02和rabbitmq03操作一致，以rabbitmq02为例
[root@rabbitmq02 ~]# chmod 600 /var/lib/rabbitmq/.erlang.cookie

[root@rabbitmq02 ~]# systemctl restart rabbitmq-server.service

[root@rabbitmq02 ~]# rabbitmqctl stop_app

[root@rabbitmq02 ~]# rabbitmqctl join_cluster --ram rabbit@rabbitmq01 

[root@rabbitmq02 ~]# rabbitmqctl start_app

[root@rabbitmq02 ~]# rabbitmq-plugins enable rabbitmq_management


# 如果上面的操作有误：执行 rabbitmqctl reset

四、搭建 rabbitmq 的镜像高可用模式集群

在一般模式集群基础上继续：

$root@rabbitmq01 \~$ # rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
