因為rabbitmq是用erlang語言寫的，所以裝rabbitmq前第一步得先裝erlang。
我們到erlang官網https://www.erlang.org/downloads下載安裝包，最新版本是22.0，下載時又被windows禁掉了，退而求其次，下21.3版本吧：
下完后通過rz上傳至wlf用戶soft目錄下，執行解壓：
$ tar xvf otp_src_21.3.tar
注意編譯前需要借用root用戶通過yum install命令先安裝ncurses-devel和openssl-devel依賴，可以切換到root用戶后執行：
yum install ncurses-devel
yum install openssl-devel
很遺憾，普通用戶這里沒法繞開root用戶，除非你的機器之前已經用root安裝過以上兩個依賴了。通過以下命令可以查看本機是否已經存在這兩個依賴：
$ rpm -qa | grep -E "ncurses-devel*|openssl-devel*" ncurses-devel-5.9-13.20130511.el7.x86_64 openssl-devel-1.0.1e-60.el7.x86_64
可以發現我這里之前已經裝了。
配置下目錄前綴，通過make命令開始編譯、安裝，貌似編譯時間有點久：
$ cd otp_src_21.3
$ ./configure --prefix=/home/wlf/erlang
檢查成功后編譯、安裝一條龍：
$ make && make install
結束后通過bin/erl命令確認安裝成功：
$ cd ~
$ cd erlang/bin
$ ./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是退出系統的方法，別忘了下面的點。
配置Erlang環境變量：
$ cd ~
$ vi .bash_profile
在bash_profile最后加入export PATH=$PATH:/home/wlf/erlang/bin這一行：
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$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/erlang/bin
保存后讓它生效：
$ source .bash_profile
------------------------------------------------------------------------分割線------------------------------------------------------------------------
搞定了erlang，再開始搞rabbitmq。同理，先去官網http://www.rabbitmq.com/download.html下載安裝包，我們選通過git下載linux二進制版本的：
會有點慢，壓縮包rabbitmq-server-generic-unix-3.7.18.tar.xz下好了通過rz上傳到wlf的soft目錄下，在soft目錄下開始解壓，需要分兩步走，先解壓xz，再解壓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是解壓即可用的，但我們可以通過在配置文件來指定一些自定義設置，先進入配置目錄：
cd rabbitmq_server-3.7.18/etc/rabbitmq/
再通過vi新增rabbitmq.env.conf指定數據節點名稱和路徑
#node name NODENAME=rabbit #data dir MNESIA_BASE=/home/wlf/rabbitmq_server-3.7.18/data
同理，新增rabbitmq.conf指定端口等設置：
#listen port listeners.tcp.default = 5673 #log dir log.dir = /home/wlf/rabbitmq_server-3.7.18/logs #open remote request loopback_users = none
配置完后記得手動創建日志目錄logs。最后我們再次使用vi打開bash_profile配置下環境變量：
# .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的執行目錄之后，保存並用source命令讓我們的配置生效。我們以后台進行方式啟動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.
克隆會話登陸wlf，查看啟動狀態：

可以看到啟動成功，使用端口5673.
如果想訪問管理界面，執行下管理插件安裝命令即可：
