创建账号、vhost、开启管理插件、删除guest账号
rabbitmqctl list_users -n rabbit@mq01
rabbitmq-plugins enable rabbitmq_management -n rabbit@mq1
rabbitmqctl add_user gadmin 123456 -n rabbit@mq01
rabbitmqctl add_user dev 123456 -n rabbit@mq1
rabbitmqctl add_user cloud 123456 -n rabbit@mq1

#分配用户标签
rabbitmqctl set_user_tags gadmin administr服务器托管网ator
rabbitmqctl set_user_tags dev administrator
rabbitmqctl set_user_tags cloud administrator
rabbitmqctl set_user_tags test administrator
添加vhost
rabbitmqctl add_vhost /dev -n rabbit@mq1
rabbitmqctl add_vhost /cloud -n rabbit@mq1
rabbitmqctl add_vhost /test -n rabbit@mq1
授权账号vhost权限
rabbitmqctl set_permissions -p / gadmin '.*' '.*' '.*' -n rabbit@mq01
rabbitmqctl set_permissions -p /dev dev '.*' '.*' '.*' -n rabbit@mq1
rabbitmqctl set_permissions -p /cloud cloud '.*' '.*' '.*' -n rabbit@mq1
rabbitmqctl set_permissions -p /test test '.*' '.*' '.*' -n rabbit@mq1
查看集群状态
rabbitmqctl cluster_status -n rabbit@mq1
# 设置权限
rabbitmqctl set_permissions -p / gadmin '.*' '.*' '.*'
rabbitmqctl delete_user guest -n rabbit@mq1
新节点加入集群
注意:
所有节点的.erlang.cookie的值要一致
如果需要root账号也能执行rabbitmqctl命令,需要把.erlang.cookie拷贝到/root/路径下
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@mq1
rabbitmqctl start_app

摘要: 冒泡排序是一种简单且常见的排序算法,通过重复遍历待排序序列,比较相邻元素并交换它们的位置,从而使较大(或较小)的元素逐渐从序列的前端移动到后端。本文将详细介绍如何用C语言实现冒泡排序,并通过代码示例进行解读。 正文: 一、冒泡排序的原理与步骤 冒泡排序…
