【rabbitmq】Centos7 下安装rabbitmq

rabbitmq安装

rabbitmq的安装依赖erlang，首先应该先安装erlang，而后安装rabbitmq；

Step1：安装erlang

erlang-rpm安装教程
选择在Centos7 上安装：

To use Erlang 20.x on CentOS 7:

# In /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/20/el/7
gpgcheck=1
gpgkey=https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

而后执行：

yum install erlang

Step2: 安装rabbitmq

参考连接

下载rpm

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_6_12/rabbitmq-server-3.6.12-1.el7.noarch.rpm

安装rpm

rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
yum install rabbitmq-server-3.6.12-1.el7.noarch.rpm

Step3: 设置开机自启动+开启服务

chkconfig rabbitmq-server on
/sbin/service rabbitmq-server stop/start/

Step4： Rabbit管理（非必须）

开启Web管理插件

rabbitmq-plugins enable rabbitmq_management

output:
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management
Applying plugin configuration to rabbit@PC-201602152056... started 6 plugins.

浏览器访问：
http://localhost:15672，
默认用户名和密码： guest/guest;
须要注意的是：guest用户仅仅提供localhost做为ip登陆；
若是远程登陆，如：http://192.168.35.129:15672/, 则会提示错误，登陆不了：

# 以下是日志输出
=WARNING REPORT==== 21-Oct-2017::23:31:33 ===
 HTTP access denied: user 'guest' - User can only log in via localhost

访问控制可参考：
Access Control (Authentication, Authorisation) in RabbitMQ
为了让guest可远程访问，须要修改rabbitmq.config中的loopback_users参数，设置为

[{rabbit, [{loopback_users, []}]}].

官网文档描述以下,可参考官方文档：RabbitMQ Configuration：

loopback_users参数：
List of users which are only permitted to connect to the broker via a loopback interface (i.e. localhost).
If you wish to allow the default guest user to connect remotely, you need to change this to [].

Default:  [<<"guest">>]

默认安装时，rabbitmq.config配置文件可能不存在，有两种方式能够设置配置文件；

• 方式1： 配置文件默认路径： /etc/rabbitmq/rabbitmq.config
• 方式2： 使用环境变量RABBITMQ_CONFIG_FILE指定 rabbitmq.config文件位置；
  说明以下：

If rabbitmq.config doesn't exist, it can be created manually. Set the RABBITMQ_CONFIG_FILE environment variable if you change the location. The Erlang runtime automatically appends the .config extension to the value of this variable.

修改完配置文件后，重启，就能够使用guest用户远程访问了；
