linux下rabbitmq 安装

安装

sudo yum -y install erlang  #安装erlang
sudo yum -y install rabbitmq-server
sudo systemctl enable rabbitmq-server
sudo systemctl start rabbitmq-server #启动服务

启动web管理系统

这一步不是必须的，命令行也可以

//生效管理插件
$ sudo rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.
//查看生效的插件,前面有e的就是已经生效的
$ sudo rabbitmq-plugins list

// 重启服务生效配置
$sudo systemctl restart rabbitmq-server 

管理界面配置

访问 127.0.0.1:15672
账号密码都是guest
登入后先需改下密码，可以直接用这个新账号，添加管理员标签后可以登陆

配置vhost

// 添加虚拟机rabbitmqctl add_vhost vhost_name
$sudo rabbitmqctl add_vhost rmq

// 创建一个用户rabbitmqctl add_user username password
$sudo rabbitmqctl add_user rmq 123456

// 为用户分配角色rabbitmqctl set_user_tags username administrator/monitoring/management
$sudo rabbitmqctl set_user_tags rmq administrator

// 设置访问权限rabbitmqctl set_permissions -p vhostname username ".*" ".*" ".*"
$sudo rabbitmqctl set_permissions -p rmq rmq  ".*" ".*" ".*"

当时又遇到一个异常，处理方法如下

重启rabbitmq很慢并报错如下：

rabbitmq-server[2528]: ERROR: epmd error for host iZ25jvky68fZ: timeout (timed out)

hostname的问题，尤其是老的阿里云主机切换过网络会出这种问提，修改/etc/hosts文件里的host指向的ip为本地即可，然后重启

如果遇到什么问题需要重新安装需卸载后删除

rm -rf /var/lib/rabbitmq/
