RabbitMQ集群安装

rpm -Uvh *.rpm --nodeps --force

安装依赖(一步步来)
rpm -ivh erlang-22.2.1-1.el7.x86_64.rpm

rpm -ivh socat-1.7.3.2-2.el7.x86_64.rpm --nodeps --force

rpm -ivh rabbitmq-server-3.8.3-1.el7.noarch.rpm

启动RabbitMQ
systemctl start rabbitmq-server
systemctl restart rabbitmq-server
systemctl status rabbitmq-server

设置RabbitMQ开机自启动
systemctl enable rabbitmq-server
#开启网页插件
rabbitmq-plugins enable rabbitmq_management
# 添加用户
rabbitmqctl add_user cnmc cnmc20230630
 
# 设置用户角色,分配操作权限
rabbitmqctl set_user_tags cnmc administrator
 
# 为用户添加资源权限(授予访问虚拟机根节点的所有权限)
rabbitmqctl set_permissions -p "/" cnmc ".*" ".*" ".*"

保证每个服务器上erlang.cookie内容一致
chmod 777 /var/lib/rabbitmq/.erlang.cookie
CRAZQSVYQHZKJJFORKFE
chmod 400 /var/lib/rabbitmq/.erlang.cookie
vim /var/lib/rabbitmq/.erlang.cookie

注意修改本地节点名称
vim /etc/rabbitmq/rabbitmq-env.conf
export RABBITMQ_NODENAME=rabbit@rabbitmq3

注意防火墙开启4369和25672端口访问权限

firewall-cmd --add-rich-rule="rule family="ipv4" source address="127.0.0.1" port protocol="tcp" port="4369" accept" --permanent
firewall-cmd --add-rich-rule="rule family="ipv4" source address="127.0.0.1" port protocol="tcp" port="25672" accept" --permanent
firewall-cmd --reload


修改hosts
vim /etc/hosts

10.2.1.199 rabbit-node1
10.2.1.200 rabbit-node2
10.2.1.201 rabbit-node3

设置服务器hostname
hostnamectl set-hostname rabbit-node1

# 在rabbit2 节点执行命令 停止并且链接到rabbit1节点
#停止节点
rabbitmqctl stop_app 
# 清空节点状态
rabbitmqctl reset 
# rabbit2和rabbit1构成集群,rabbit2必须能通过rabbit1的主机名ping通
rabbitmqctl join_cluster rabbit@ecs-5167-0615539
# 开启rabbitmq服务
rabbitmqctl start_app

固定服务名
rabbitmq-env.conf
echo 'NODENAME=rabbit@ecs-c775-0615708' >> /etc/rabbitmq/rabbitmq-env.conf

firewall-cmd --zone=public --add-port=5672/tcp --permanent
firewall-cmd --zone=public --add-port=15672/tcp --permanent

卸载erlang
yum remove erlang-erts-R16B-03.18.el7.x86_64
