rabbitmq集羣搭建

mq集羣:

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（全部節點執行）

yum -y install vim bash-completion rabbitmq-server

 

2.設置selinux和防火牆（全部節點執行）

# 重啓生效
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

# 臨時生效
setenforce 0

systemctl stop firewalld
systemctl disable firewalld
systemctl mask firewalld

 

3.設置主機名
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
各個節點：

systemctl start rabbitmq-server
systemctl enable rabbitmq-server

 

192.168.6.61（以第1臺節點爲master節點）：

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加入集羣:

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用戶和許可（192.168.6.61執行）

rabbitmqctl add_user 用戶名 密碼
rabbitmqctl set_user_tags 用戶名 administrator
rabbitmqctl set_permissions -p / 用戶名 '.*' '.*' '.*'

 

# 配置鏡像隊列（messages自動同步）

rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all","ha-sync-mode":"automatic"}'

 

# 修改本節點爲ram模式

rabbitmqctl stop_app
rabbitmqctl change_cluster_node_type ram
rabbitmqctl start_app
