依赖关系：
版本依赖一定要提前看清楚。
RabbitMQ相关版本依赖关系查看
https://www.rabbitmq.com/which-erlang.html
可以看到要求版本Erlang21.3.X或22.X
而Erlang则依赖于wxwidgets
所以我们应该先安装wxwidgets再安装erlang最后再安装RabbitMQ
（1）推荐安装方式：
yum包安装
erlang安装包下载地址：选择合适自己系统的版本
https://www.erlang-solutions.com/resources/download.html
rabbitmq安装包下载地址：
https://www.rabbitmq.com/install-rpm.html#downloads
直接执行yum install 加包名直接安装即可。注意先安装erlang
（2）编译安装：（后来又试了一次，有报错，服务无法启动。。。）
我也不知道这个属于哪种安装方式。目前我是用来做测试的，所以不讲究这个。
简单一点地说，我这个教程使用的方法相当于Windows系统下的免安装绿色版
具体步骤：
一. 安装wxwidgets
[root@localhost ~]# yum install gcc-c++ ncurses-devel fop unixODBC-devel mesa-libGLU-devel gtk3* -y #提前安装好相关依赖
[root@localhost ~]# wget https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.3/wxWidgets-3.1.3.tar.bz2
[root@localhost ~]# yum install bzip2 -y
[root@localhost ~]# bzip2 -d wxWidgets-3.1.3.tar.bz2
[root@localhost ~]# tar -xvf wxWidgets-3.1.3.tar
[root@localhost ~]# cd wxWidgets-3.1.3
[root@localhost wxWidgets-3.1.3]# ./configure
[root@localhost wxWidgets-3.1.3]# make
[root@localhost wxWidgets-3.1.3]# make install
[root@localhost wxWidgets-3.1.3]# ldconfig
二. 安装Erlang
建议从官方网站下www.erlang.org，最近一次安装发现下载的包不能正常编译安装，使用原来的就可以，不知道是不是官方的包出问题了还是怎么回事
[root@localhost ~]# wget https://erlang.org/download/otp_src_22.1.tar.gz #下载erlang
[root@localhost ~]# tar -zxvf otp_src_22.1.tar.gz #解压erlang压缩包
[root@localhost ~]# cd otp_src_22.1
[root@localhost otp_src_22.1]# grep -A 11 "### Compiling from source" README.md #查看README.MD文档，可以看到有相关的安装说明。grep -A可以查看相关上下文的下文指定行数
### Compiling from source
To compile Erlang from source, run the following commands. The complete building and installation instructions [can be found here](HOWTO/INSTALL.md).
```
git clone https://github.com/erlang/otp.git
cd otp
./otp_build autoconf
./configure
make
make install
```
Alternatively, you can use [Kerl](https://github.com/kerl/kerl), a script that lets you easily build Erlang with a few commands.
[root@localhost otp_src_22.1]# ./configure --prefix=/usr/local/erlang --without-javac #使用--prefix指定安装目录。wx: Can not link the wx driver, wx will NOT be useable可忽略
[root@localhost otp_src_22.1]# make
[root@localhost otp_src_22.1]# make install
[root@localhost otp_src_22.1]# echo 'export PATH=$PATH:/usr/local/erlang/bin'>> /etc/profile #修改系统环境变量
[root@localhost otp_src_22.1]# source /etc/profile #使系统环境变量生效
[root@localhost otp_src_22.1]# erl #测试erl是否安装成功，如下显示说明成功
Erlang/OTP 22 [erts-10.5] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe]
Eshell V10.5 (abort with ^G)

三. 运行RabbitMQ
[root@localhost ~]# xz -d rabbitmq-server-generic-unix-3.8.2-rc.1.tar.xz
[root@localhost ~]# cd rabbitmq_server-3.8.2-rc.1/
[root@localhost rabbitmq_server-3.8.2-rc.1]# ls

四. rabbitmq常用命令
./rabbitmq-server #启动RabbitMQ rabbitmq-plugins enable rabbitmq_management #启用web端，会启动15672端口 rabbitmqctl add_user admin 123456 #添加admin用户，密码为123456 rabbitmqctl set_user_tags admin administrator #设置admin为administrator rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*" #允许admin远程登录 ./rabbitmqctl list_users #查看admin是否是administrator
