mq集群:
192.168.6.61 rabbitmq-server1 master 192.168.6.62 rabbitmq-server2 slave 192.168.6.71 rabbitmq-server3 slave
1.配置yum源（所有节点执行）
yum -y install vim bash-completion rabbitmq-server
2.设置selinux和防火墙（所有节点执行）
# 重启生效
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
# 临时生效
setenforce 0
systemctl stop firewalld systemctl disable firewalld systemctl mask firewalld
3.设置主机名
192.168.6.61:
echo rabbitmq-server1 > /etc/hostname hostnamectl set-hostname rabbitmq-server1 echo 192.168.6.61 rabbitmq-server1 >> /etc/hosts echo 192.168.6.62 rabbitmq-server2 >> /etc/hosts echo 192.168.6.71 rabbitmq-server3 >> /etc/hosts
192.168.6.62:
echo rabbitmq-server2 > /etc/hostname hostnamectl set-hostname rabbitmq-server2 echo 192.168.6.61 rabbitmq-server1 >> /etc/hosts echo 192.168.6.62 rabbitmq-server2 >> /etc/hosts echo 192.168.6.71 rabbitmq-server3 >> /etc/hosts
192.168.6.71:
echo rabbitmq-server3 > /etc/hostname hostnamectl set-hostname rabbitmq-server3 echo 192.168.6.61 rabbitmq-server1 >> /etc/hosts echo 192.168.6.62 rabbitmq-server2 >> /etc/hosts echo 192.168.6.71 rabbitmq-server3 >> /etc/hosts
4.配置rabbitmq-server
各个节点：
systemctl start rabbitmq-server
systemctl enable rabbitmq-server
192.168.6.61（以第1台节点为master节点）：
scp /var/lib/rabbitmq/.erlang.cookie 192.168.6.62:/var/lib/rabbitmq/ scp /var/lib/rabbitmq/.erlang.cookie 192.168.6.71:/var/lib/rabbitmq/
192.168.6.62和192.168.6.71加入集群:
chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie chmod 400 /var/lib/rabbitmq/.erlang.cookie systemctl restart rabbitmq-server rabbitmqctl stop_app rabbitmqctl join_cluster rabbit@rabbitmq-server1 rabbitmqctl start_app
# 配置rabbitmq用户和许可（192.168.6.61执行）
rabbitmqctl add_user 用户名 密码 rabbitmqctl set_user_tags 用户名 administrator rabbitmqctl set_permissions -p / 用户名 '.*' '.*' '.*'
# 配置镜像队列（messages自动同步）
rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all","ha-sync-mode":"automatic"}'
# 修改本节点为ram模式
rabbitmqctl stop_app
rabbitmqctl change_cluster_node_type ram
rabbitmqctl start_app
# haproxy配置：
