repo_gpgcheck=0
enabled=1

刷新缓存

yum clean all

yum makecache

安装erlang

解决方案:

删除旧的erlang其他依赖

yum remove erlang-erts-R16B-03.18.el7.x86_64

安装rabbitmq

vim /etc/yum.repos.d/rabbitmq.repo

[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.8.x/el/7/
gpgcheck=0
repo_gpgcheck=0
enabled=1

刷新缓存

yum clean all

yum makecache

安装rabbitmq命令

yum install rabbitmq-server

查询rabbitmq状态

systemctl status rabbitmq-server

创建开机自启动

systemctl enable rabbitmq-server

启动rabbitmq的web管理后台界面命令

rabbitmq-plugins enable rabbitmq_management

服务地址:

http://{node-hostname}:15672/

默认账号:guest 密码:guest

只能 localhost，修改配置允许远程访问:

没有配置文件创建配置文件：

vim /etc/rabbitmq/rabbitmq.config

经典格式

# DANGER ZONE!
#
# allowing remote connections for default user is highly discouraged
# as it dramatically decreases the security of the system. Delete the user
# instead and create a new one with generated secure credentials.
loopback_users = none

新格式

%% DANGER ZONE!
%%
%% Allowing remote connections for default user is highly discouraged
%% as it dramatically decreases the security of the system. Delete the user
%% instead and create a new one with generated secure credentials.
[{rabbit, [{loopback_users, []}]}].

也可以修改下面文件:

vim /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.3/ebin/rabbit.app

找到{loopback_users, [<<"guest">>]},

修改为{loopback_users, []},

新增用户 账号:admin 密码:

rabbitmqctl add_user admin pwd

分配角色 超级管理员

rabbitmqctl set_user_tags admin administrator

更改密码

rabbitmqctl change_password admin 123456

重启

systemctl restart rabbitmq-server

springBoot 启动找不到挂载点,进入web后台设置挂载点

我遇到的服务起不来，配置被我玩坏了，解决方案

Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

服务起不来:

有一种解决版本是将“/var/lib/rabbitmq/mnesia/”目录下的所有内容删掉（rm -rf *），然后重新启动再配置。
