rabbitmq集群搭建

防火墙添加并重启

-A INPUT -p tcp -m multiport --dports 4369,25672,5672,15672  -j ACCEPT

安装

cd /usr/local/src/; wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.16/rabbitmq-server-3.7.16-1.el7.noarch.rpm
curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash
yum install erlang -y
yum install rabbitmq-server-3.7.16-1.el7.noarch.rpm -y 

四台服务器的/etc/hosts配置统一

192.168.1.1 node1 
192.168.1.1 node2 
192.168.1.1 node3 
192.168.1.1 node4 

确认每一台的.erlang.cookie的配置统一

chmod 700 /var/lib/rabbitmq/.erlang.cookie
echo -n "SECBJUFBZFRQWNETDDDU" > /var/lib/rabbitmq/.erlang.cookie
cat /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie

其他节点添加到磁盘节点

rabbitmqctl join_cluster rabbit@node01

其他节点添加为内存节点

rabbitmqctl stop_app ;rabbitmqctl change_cluster_node_type ram ;rabbitmqctl start_app

开机自启

systemctl enable rabbitmq-server
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl cluster_status

镜像模式

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

设置用户

rabbitmqctl add_user wwdd yesdx#EDC
rabbitmqctl set_permissions -p / wwdd ".*" ".*" ".*"

**访问:**http://IP:15672

haproxy 到rabbitmq

yum install -y haproxy cd /etc/haproxy haproxy -f /etc/haproxy/haproxy.cfg 配置文件示例

    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    #    local2.*                       /var/log/haproxy.log
    #
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
