Centos 7 下安装RabbitMQ，并通过web访问_failed to start socat error:enoent

一、安装Erlang

1、下载esl-erlang_21.0-1~centos~7_amd64.rpm

wget https://packages.erlang-solutions.com/erlang/esl-erlang/FLAVOUR_1_general/esl-erlang_21.0-1~centos~7_amd64.rpm

2、安装

rpm -ivh esl-erlang_21.0-1~centos~7_amd64.rpm --force --nodeps

3、查看安装

  [root@localhost opt]# yum list|grep erlang
  esl-erlang.x86_64                           21.0-1                     installed

二、安装RabbitMQ

1、下载rabbitmq-server-3.7.7-1

wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.7/rabbitmq-server-3.7.7-1.el7.noarch.rpm

2、安装

rpm -ivh rabbitmq-server-3.7.7-1.el7.noarch.rpm --force --nodeps

3、查看安装

  [root@localhost opt]# yum list|grep rabbit
  rabbitmq-server.noarch                      3.7.7-1.el7                installed
  librabbitmq.i686                            0.8.0-2.el7                base     
  librabbitmq.x86_64                          0.8.0-2.el7                base     
  librabbitmq-devel.i686                      0.8.0-2.el7                base     
  librabbitmq-devel.x86_64                    0.8.0-2.el7                base     
  librabbitmq-examples.x86_64                 0.8.0-2.el7                base                            21.0-1                     installed

3、配置远程用户访问

1、新建配置文件

 vi /etc/rabbitmq/rabbitmq.conf

  #默认用户名
  default_user = guest
  #默认密码
  default_pass = guest
  #远程用户访问
  loopback_users = none

2、启动rabbitmq服务

/sbin/service rabbitmq-server start

3、查看运行

  [root@localhost opt]# /sbin/service rabbitmq-server status
  Redirecting to /bin/systemctl status rabbitmq-server.service
  ● rabbitmq-server.service - RabbitMQ broker

4、开启RabbitMQ web访问

  rabbitmq-plugins enable rabbitmq_management
  /sbin/service rabbitmq-server stop
  /sbin/service rabbitmq-server start

5、开启端口15672，5672

  [root@localhost opt]# firewall-cmd --permanent --add-port=15672/tcp
  success
  [root@localhost opt]# firewall-cmd --permanent --add-port=5672/tcp 
  success
  [root@localhost opt]# service network restart
  Restarting network (via systemctl):                        [  OK  ]
  [root@localhost opt]# 

6、设置开机启动

chkconfig rabbitmq-server on

7、添加admin，并赋予administrator权限

添加admin用户，密码设置为admin。

sudo rabbitmqctl add_user  admin  admin  

赋予权限

sudo rabbitmqctl set_user_tags admin administrator

赋予virtual host中所有资源的配置、写、读权限以便管理其中的资源

sudo rabbitmqctl  set_permissions -p / admin '.*' '.*' '.*'

安装完毕web访问

浏览器输入
