CentOS7 安装RabbitMQ 亲测
使用
yum install erlang命令安装了erlang，然后再RabbitMQ下载了rabbitmq-server-3.7.4-1.el7.noarch.rpm在执行rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm命令时，报错
warning: rabbitmq-server-3.7.4-1.el7.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch
socat is needed by rabbitmq-server-3.7.4-1.el7.noarch
这儿存在两个问题： 问题一、
erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch问题二、socat is needed by rabbitmq-server-3.7.4-1.el7.noarch接下来围绕这两个问题。
准备
RabbitMQ：rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm 下载请戳这儿； erlang：下载请戳这儿
问题二、socat is needed by rabbitmq-server-3.7.4-1.el7.noarch
解决方案：使用命令
yum -y install socat进行安装即可，我看有些博主在这步的时候 会遇到另一个问题会报错没有socat包或是找不到socat包，解决方法安装centos的epel的扩展源，这个问题解决方案：yum -y install epel-release执行这个命令后再执行之前的 socat安装命令
问题一、erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch
由于我们使用
yum install erlang命令安装了erlang，它的版本不支持rabbitmq-server-3.7.4-1.el7.noarch所以我们重新安装提示给的 19.3的版本。
准备安装Erlang
首先我们需要准备安装环境
依赖环境的安装-如果需要用编译安装erlang语言环境，需要安装C++编译
yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC unixODBC-devel httpd python-simplejson我将这些东西重新用yum命令安装一下后 在进行编译，然后编译就没有报错。再次执行安装命令。
获取Erlang(上面提示19.3的版本就可以，但是我安装了不行 所以下了个不是最新的版本试试)

解压erlang安装包，会有很多的东西
# tar -xzvf otp_src_20.2.tar.gz
然后我们在进入解压后的目录
# cd otp_src_20.2
编译安装erlang语言环境 prefix=/usr/local/erlang 为安装目录
./configure --prefix=/usr/local/erlang --enable-smp-support --enable-threads --enable-sctp --enable-kernel-poll --enable-hipe --with-ssl --without-javac
若是安装环境没准备好 这儿编译会报错
configure: error: No curses library functions found
configure: error: /bin/sh '/usr/local/tool/otp_src_19.3/erts/configure' failed for erts
开始安装编译：
make && make install
配置erlang环境变量:
vim /etc/profile
export PATH=$PATH:/usr/local/erlang/bin
//执行下面命令修改配置文件立即生效
source /etc/profil
验证是否安装成功：
//注释：输入erl Erlang/OTP 17 [erts-6.2] [source] [smp:2:2] [async-threads:10] [kernel-poll:false]，会输出版本号信息
# erl Erlang/OTP 17 [erts-6.2] [source] [smp:2:2] [async-threads:10] [kernel-poll:false]
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V5.10.4 (abort with ^G)

开始安装rabbitmq rpm包
需要回到 rabbitmq 安装包目录
执行rpm安装命令
# rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm
安装了前面准备的东西 但是还是报错
[root@ tool]# rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm
warning: rabbitmq-server-3.7.4-1.el7.noarch.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
erlang >= 19.3 is needed by rabbitmq-server-3.7.4-1.el7.noarch
这种方式会提示版本需大于R13，加上 -nodeps 就ok了
[root@izbp1e0h5tks006vnlaro4z tool]# rpm -ivh --nodeps --force rabbitmq-server-3.7.4-1.el7.noarch.rpm

上面的错误是因为配置文件 我修改了没有立即生效， PS： 需要在配置文件
/etc/profile,中添加export PATH=$PATH:/usr/rabbitmq/sbin，保存并使文件生效： source /erc/profile；在重新安装一遍
[root@izbp1e0h5tks006vnlaro4z tool]# rpm -ivh --nodeps --force rabbitmq-server-3.7.4-1.el7.noarch.rpm
