OpenStack集群安装-04_RabbitMQ-cluster集群

安装配置RabbitMQ

安装软件

for HOST in controller{1..3}; do
    echo "--------------- $HOST ---------------"
    ssh -T $HOST <<'EOF'
    # 安装 rabbitmq
    yum -y install rabbitmq-server erlang socat

    # 跟随系统启动
    systemctl enable rabbitmq-server

    # 启用web插件(端口15672)
    rabbitmq-plugins enable rabbitmq_management
EOF
done

controller1启动服务

systemctl start rabbitmq-server

同步认证 Cookie 文件到其他节点

scp /var/lib/rabbitmq/.erlang.cookie controller2:/var/lib/rabbitmq/
scp /var/lib/rabbitmq/.erlang.cookie controller3:/var/lib/rabbitmq/

controller2,3启动服务

ssh controller2 "systemctl restart rabbitmq-server"
ssh controller3 "systemctl restart rabbitmq-server"

配置集群

使用Disk模式

systemctl stop rabbitmq-server
pkill beam.smp
rabbitmqctl stop
rabbitmq-server -detached 
rabbitmqctl cluster_status     #查看状态

加入节点controller1

for HOST in  controller{1..3}; do
    ssh -T $HOST <<EOF
    systemctl stop rabbitmq-server
    pkill beam.smp
    rabbitmq-server -detached 
    rabbitmqctl stop_app
    rabbitmqctl join_cluster rabbit@controller1
    rabbitmqctl start_app
    rabbitmqctl cluster_status
    sleep 2
EOF
done

rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'  # 设置镜像队列
rabbitmqctl set_cluster_name RabbitMQ-Cluster          # 更改群集名称
rabbitmqctl cluster_status                             # 查看群集状态

验证

# 查看群集状态(验证有3台节点)
rabbitmqctl cluster_status

#[root@controller1 ~]# rabbitmqctl cluster_status               
#Cluster status of node rabbit@controller1 ...
#[{nodes,[{disc,    [rabbit@controller1,rabbit@controller2,rabbit@controller3]}]},
# {running_nodes,[rabbit@controller3,rabbit@controller2,rabbit@controller1]},
# {cluster_name,<<"RabbitMQ-Cluster">>},
# {partitions,[]},
# {alarms,[{rabbit@controller3,[]},
#          {rabbit@controller2,[]},
#          {rabbit@controller1,[]}]}]

创建RabbitMQ用户及密码

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl add_user openstack openstack
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmqctl set_user_tags openstack administrator

Haproxy 配置

添加 RabbitMQ 代理

cat <<EOF >>/etc/haproxy/haproxy.cfg

########## RabbitMQ ##########
listen RabbitMQ-Server
  bind controller:5673
  mode tcp
  balance roundrobin
  option tcpka
  timeout client 3h
  timeout server 3h
  option clitcpka
  server controller1 controller1:5672 check inter 5s rise 2 fall 3
  server controller2 controller2:5672 check inter 5s rise 2 fall 3
  server controller3 controller3:5672 check inter 5s rise 2 fall 3

listen RabbitMQ-Web
  bind controller:15673
  mode tcp
  balance roundrobin
  option tcpka
  server controller1 controller1:15672 check inter 5s rise 2 fall 3
  server controller2 controller2:15672 check inter 5s rise 2 fall 3
  server controller3 controller3:15672 check inter 5s rise 2 fall 3
EOF

同步 haproxy 配置文件

scp /etc/haproxy/haproxy.cfg controller2:/etc/haproxy/haproxy.cfg
scp /etc/haproxy/haproxy.cfg controller3:/etc/haproxy/haproxy.cfg

重启服务

systemctl restart haproxy
ssh controller2 "systemctl restart haproxy"
ssh controller3 "systemctl restart haproxy"

验证

浏览器打开 http://192.168.0.11:1080/admin 查看RabbitMQ-Server,RabbitMQ-Web 状态

浏览器打开 http://10.0.0.10:15673 登录WebUI管理页面,查看服务状态 用户名:密码 / admin:admin

命令行执行查看集群节点：
rabbitmqctl cluster_status

使用脚本

site='http://home.onlycloud.xin'
wget $site/code/openstack-04_rabbitmq-cluster.sh -O openstack-rabbitmq.sh
sh openstack-rabbitmq.sh
