因为rabbitmq是用erlang语言写的，所以装rabbitmq前必须先装好erlang。
我们到erlang官网https://www.erlang.org/downloads下载安装包，最新版本是22.0，下载时又被windows禁掉了，退而求其次，下21.3版本吧：
下完后通过rz上传至wlf用户soft目录下，执行解压：
$ tar xvf otp_src_21.3.tar配置下目录前缀，通过make命令开始编译、安装，貌似编译时间有点久：
$ cd otp_src_21.3
$ make
结束后通过bin/erl命令确认安装成功：
$ erl Erlang/OTP 21 [erts-10.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] Eshell V10.3 (abort with ^G) 1> halt() 1> .
halt是退出系统的方法，别忘了下面的点。
配置Erlang环境变量：
$ cd ~
$ vi .bash_profile在bash_profile最后加入export PATH=$PATH:/home/wlf/erlang/bin这一行：
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/.local/bin:$HOME/bin export PATH # Java_Home JAVA_HOME=/home/wlf/jdk1.8.0_221 CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin export PATH CLASSPATH JaVA_HOME # erlang export PATH=$PATH:/home/wlf/otp_src_21.3/bin
保存后让它生效：
$ source .bash_profile
注意普通用户没法通过yum安装ncurses-devel、openssl-devel等依赖，也没法执行make install，所以上面并没有这些操作。
搞定了erlang，再开始搞rabbitmq。同理，先去官网http://www.rabbitmq.com/download.html下载安装包，我们选通过git下载linux二进制版本的：
会有点慢，压缩包rabbitmq-server-generic-unix-3.7.18.tar.xz下好了通过rz上传到wlf的soft目录下，在soft目录下开始解压，需要分两步走，先解压xz，再解压tar：
$ xz -d rabbitmq-server-generic-unix-3.7.18.tar.xz $ cd .. $ tar xvf soft/rabbitmq-server-generic-unix-3.7.18.tar
rabbitmq是解压即可用的，但我们可以通过在配置文件来指定一些自定义设置，先进入配置目录：
cd rabbitmq_server-3.7.18/etc/rabbitmq/
再通过vi新增rabbitmq.env.conf指定数据节点名称和路径
#node name NODENAME=rabbit #data dir MNESIA_BASE=/home/wlf/rabbitmq_server-3.7.18/data
同理，新增rabbitmq.conf指定端口等设置：
#listen port listeners.tcp.default = 5673 #log dir log.dir = /home/wlf/rabbitmq_server-3.7.18/logs #open remote request loopback_users = none
配置完后记得手动创建日志目录logs。最后我们再次使用vi打开bash_profile配置下环境变量：
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/.local/bin:$HOME/bin export PATH # Java_Home JAVA_HOME=/home/wlf/jdk1.8.0_221 CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin export PATH CLASSPATH JaVA_HOME # erlang export PATH=$PATH:/home/wlf/otp_src_21.3/bin # rabbitmq export PATH=$PATH:/home/wlf/rabbitmq_server-3.7.18/sbin
加上最后一行指定rabbitmq的执行目录之后，保存并用source命令让我们的配置生效。我们以后台进行方式启动rabbitmq：
$ rabbitmq-server -detatched ## ## ## ## RabbitMQ 3.7.18. Copyright (C) 2007-2019 Pivotal Software, Inc. ########## Licensed under the MPL. See https://www.rabbitmq.com/ ###### ## ########## Logs: /home/wlf/rabbitmq_server-3.7.18/var/log/rabbitmq/rabbit.log /home/wlf/rabbitmq_server-3.7.18/var/log/rabbitmq/rabbit_upgrade.log Starting broker... completed with 0 plugins.
克隆会话登陆wlf，查看启动状态：

可以看到启动成功，使用端口5673.
