yum update -y

yum install socat logrotate -y

yum install erlang rabbitmq-server -y

编译安装rabbitmq

https://github.com/rabbitmq/rabbitmq-server/tags #历史版本

在安装RabbitMQ中需要注意：
1、RabbitMQ依赖于Erlang，需要先安装Erlang
2、Erlang和RabbitMQ版本有对应关系
https://www.rabbitmq.com/which-erlang.html

安装Erlang

1.先安装一些需要的依赖：

yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget

2.下载对应版本的Erlang

wget http://erlang.org/download/otp_src_24.0.tar.gz

3.解压编译安装配置环境变量

tar -zxvf otp_src_24.0.tar.gz
cd otp_src_24.0/
./configure --prefix=/usr/local/erlang


make && make install   



vim /etc/profile
export PATH=$PATH:/usr/local/erlang/bin     #注意路径的改变
source /etc/profile

下载rabbitmq二进制包

https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.8.16

解压

tar -xvf rabbitmq-server-generic-unix-3.8.16.tar.xz

.配置环境变量

vim /etc/profile

export PATH=$PATH:/usr/local/rabbitmq_server-3.8.16/sbin   #注意路径的改变

source /etc/profile

启动RabbitMQ

进入/usr/local/rabbitmq_server-3.8.16/sbin目录 #注意路径

cd /usr/local/rabbitmq_server-3.8.16/sbin
./rabbitmq-server start

启动成功了如下：

或者后台启动rabbitmq服务

./rabbitmq-server -detached

添加其他用户

因为guest用户只能在本机访问，添加一个admin用户，密码也是admin

rabbitmqctl add_user admin admin     
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

启用管理插件

./rabbitmq-plugins enable rabbitmq_management

访问：http://虚拟机IP:15672 (记得配置防火墙开通端口或者关掉防火墙)

用户权限操作

创建用户

rabbitmqctl add_user {用户名} {密码}

// 设置权限
rabbitmqctl set_user_tags {用户名} {权限}

例：创建一个超级用户

rabbitmqctl add_user admin1 admin1
rabbitmqctl set_user_tags admin1 administrator

查看用户列表

rabbitmqctl list_users

为用户赋权

// 使用户user1具有vhost1这个virtual host中所有资源的配置、写、读权限以便管理其中的资源
rabbitmqctl  set_permissions -p vhost1 user1 '.*' '.*' '.*' 

// 查看权限
rabbitmqctl list_user_permissions user1

rabbitmqctl list_permissions -p vhost1

// 清除权限
rabbitmqctl clear_permissions [-p VHostPath] User

删除用户

rabbitmqctl delete_user Username

修改用户的密码

rabbitmqctl change_password Username Newpassword

修改内存，硬盘限制

rabbitmqctl set_vm_memory_high_watermark 0.6     命令临时修改，重启失效 
rabbitmqctl set_disk_free_limit 5GB

写在配置文件里边，/etc/rabbitmq/rabbitmq.conf   文件默认不存在，需要手动创建   ps:二进制安装在目录里边的 /etc/ 下
vm_memory_high_watermark.relative = 0.6    
vm_memory_high_watermark.absolute = 2GB

rabbitmq集群

集群角色：

内存节点：只将数据保存到内存

磁盘节点：保存数据到内存和磁盘

内存节点虽然不写入磁盘，但是它执行比磁盘节点要好，集群中，只需要一个磁盘节点来保存数据就足够了，如果集群中只有内存结点，那么不能全部停止他们，否则所有数据消息在服务器全部停机之后都会丢失
