安装RabbitMq

安装参考：

参考：https://www.jianshu.com/p/ed07a5a913c6 （简书:erlang版本过低啊，安装失败）

参考：https://jingyan.baidu.com/article/456c463b16f3820a583144a1.html （百度：No package rabbitmq-server-3.6.8-1.el7.noarch.rpm available）

安装过程：

1，yum安装基本依赖

yum -y update
yum install gcc gcc-c++ glibc-devel make epel-release ncurses-devel openssl-devel autoconf java-1.8.0-openjdk-devel git wget wxBase.x86_64 socat

2，安装erlang依赖

#一般安装：貌似版本偏低
yum install -y erlang
//验证是否成功
erl #进入erlang执行环境

#安装新版本的erlang
wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
yum install -y erlang
erl -version

3，安装rabbitmq

//方法1：百度的(失败)
//导入RabbitMQ源

rpm -Uvh https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.8/rabbitmq-server-3.6.8-1.el7.noarch.rpm

//安装RabbitMQ公共库秘钥

rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

//安装RabbitMQ：结果是 no package available

yum install rabbitmq-server-3.6.8-1.el7.noarch.rpm


//方法2：（知乎的：配合安装新版本的erlang成功了）
//安装rabbitmq
wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.15/rabbitmq-server-3.7.15-1.el7.noarch.rpm

//导入秘钥
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

//安装
yum install rabbitmq-server-3.7.15-1.el7.noarch.rpm

4,操作和管理

#安装成功后需要启动
systemctl start rabbitmq-server
systemctl enable rabbitmq-server


# 启用web管理界面
rabbitmq-plugins enable rabbitmq_management

# guest用户只能用于localhost访问
# 添加新用户及授权

rabbitmqctl add_user fort fort #账号：fort 密码：fort

rabbitmqctl set_user_tags fort administrator

rabbitmqctl set_permissions -p / fort '.*' '.*' '.*'

rabbitmqctl list_permissions

# 访问ip:15672即可进入管理界面 #需要开启防火墙

安装遇到问题

1，yum源问题：参考: https://www.runoob.com/linux/linux-yum.html

//备份默认的yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

//配置国内163源
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
mv CentOS7-Base-163.repo CentOS-Base.repo

//生成缓存
yum clean all
yum makecache

//配置rpm包
rpm -uvh XXXX
//使用rpm包安装
yun intall XXXX

2，安装RabbitMQ报错

rpm -ivh rabbitmq-server-3.6.15-1.el7.noarch.rpm 

warning: rabbitmq-server-3.6.15-1.el7.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
    socat is needed by rabbitmq-server-3.6.15-1.el7.noarch

//解决：
yum install socat
