Ubuntu：RabbitMq安装与踩雷

使用rabbitmq的库安装erlang，脚本如下:

#!/bin/sh

sudo apt-get install curl gnupg debian-keyring debian-archive-keyring apt-transport-https -y

## Team RabbitMQ's main signing key
sudo apt-key adv --keyserver "hkps://keys.openpgp.org" --recv-keys "0x0A9AF2115F4687BD29803A206B73A36E6026DFCA"
## Cloudsmith: modern Erlang repository
curl -1sLf https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/gpg.E495BB49CC4BBE5B.key | sudo apt-key add -
## Cloudsmith: RabbitMQ repository
curl -1sLf https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/gpg.9F4587F226208342.key | sudo apt-key add -

## Add apt repositories maintained by Team RabbitMQ
sudo tee /etc/apt/sources.list.d/rabbitmq.list <<EOF
## Provides modern Erlang/OTP releases
##
deb https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/deb/ubuntu bionic main
deb-src https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/deb/ubuntu bionic main

## Provides RabbitMQ
##
deb https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu bionic main
deb-src https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu bionic main
EOF

## Update package indices
sudo apt-get update -y

## Install Erlang packages
sudo apt-get install -y erlang-base \
                        erlang-asn1 erlang-crypto erlang-eldap erlang-ftp erlang-inets \
                        erlang-mnesia erlang-os-mon erlang-parsetools erlang-public-key \
                        erlang-runtime-tools erlang-snmp erlang-ssl \
                        erlang-syntax-tools erlang-tftp erlang-tools erlang-xmerl

安装完erl，一定要测试一下erl好不好用，如报以下错误

$ erl
/usr/lib/erlang/erts-12.0.2/bin/beam.smp: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

安装 $ sudo apt-get install libncurses5

$ erl                             
Erlang/OTP 24 [erts-12.0.2] [source] [64-bit] [smp:6:6] [ds:6:6:10] [async-threads:1] [jit]

Eshell V12.0.2  (abort with ^G)
1>

然后安装rabbitmq

## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

查询rabbitmq状态

$ service rabbitmq-server status
● rabbitmq-server.service - RabbitMQ broker
     Loaded: loaded (/lib/systemd/system/rabbitmq-server.service; enabled; vendor preset: enabled)

             └─97358 inet_gethost 4

关闭rabbitmq $ service rabbitmq-server stop

安装rabbitmq管理界面

$ sudo rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node [email protected]:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to [email protected]...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

set 3 plugins.
Offline change; changes will take effect at broker restart.

$ service rabbitmq-server start

然后访问15672端口，就可以看到rabbitmq的后台界面啦
http://localhost:15672/
初始账户、密码 都是guest

远程服务器

如果访问不了，可能是你的服务器开启了防火墙，可以选择开放端口，或者关闭防火墙

systemctl stop firewalld

远程服务器也不能使用默认的账户密码登陆后台，需要在控制台新创建用户

##创建账号，admin，密码123
rabbitmqctl add_user admin 123
##设置用户角色
rabbitmqctl set_user_tags admin administrator
##设置用户权限
##rabbitmqctl set_permissions [-p <vhostpath>] <user> <conf> <write> <read>
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
##当前用户和角色
rabbitmqctl list_users
