centos7.8环境安装rabbitmq3.8.5最新版并设置集群
一、编译安装,单机设置#1.增加用户groupadd rabbitmquseradd rabbitmq -g rabbitmq -s /sbin/nologin#2.安装必须编译基础包yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel#3.安装socatyum install socat -yyum install wxWidgets* -yyum install gtk+.x86_64 -y#4.环境变量，否则编译erlang可能会有问题PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/libexec/wxGTK3#5.下载ERLANG源码包wget http://erlang.org/download/otp_src_19.0.tar.gz（可不下载）wget https://erlang.org/download/otp_src_22.1.tar.gzwget https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.3/wxWidgets-3.1.3.tar.bz2（可不下载）#6.解压并安装（低版本）mkdir -p /usr/local/erlangtar xvf otp_src_19.0.tar.gzcd otp_src_19.0./configure --prefix=/usr/local/erlang --with-ssl --enable-threads --enable-smmp-support -enable-kernel-poll --enable-hipe --without-javacmake && make install#6.解压并安装（高版本）mkdir -p /usr/local/erlangtar xvf otp_src_22.1.tar.gzcd otp_src_22.1./configure --prefix=/usr/local/erlang --with-ssl=/usr/local/lab/openssl --enable-threads --enable-smmp-support -enable-kernel-poll --enable-hipe --without-javacmake && make install#7.解压并安装(由于是通过yum安装，无需执行，如果是编译安装可以按照下面方法)bzip2 -d wxWidgets-3.1.3.tar.bz2 tar xvf wxWidgets-3.1.3.tarcd wxWidgets-3.1.3./configure --with-opengl --enable-debug --enable-unicode#8.修改环境变量vi /etc/profileERLANG_HOME=/usr/local/erlangPATH=$ERLANG_HOME/bin:$PATHexport ERLANG_HOMEexport PATH#9.生效环境变量source /etc/profile#10.测试是否支持ERLANG语言,输入erl后会弹出提示 按CTRL+C 退出erl#11. 安装simpleJson wget https://github.com/simplejson/simplejson/releases/download/v3.16.1/simplejson-3.16.1.tar.gztar zxvf simplejson-3.16.1.tar.gzcd simplejson-3.16.1python setup.py install#12.下载rabbitmq二进制免编译包（最新版本）cd /usr/local/srcwget wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.5/rabbitmq-server-generic-unix-3.8.5.tar.xz#12.下载rabbitmq二进制免编译包cd /usr/local/srcwget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.10/rabbitmq-server-generic-unix-3.6.10.tar.xz#13.解压并安装xz -d rabbitmq-server-generic-unix-3.8.5.tar.xztar xvf rabbitmq-server-generic-unix-3.8.5.tarmv rabbitmq_server-3.8.5 /usr/localcd /usr/local/ln -s rrabbitmq_server-3.8.5 rabbitmqcd ./rabbitmq/sbin/#14.修改/etc/profile文件，添加下面的环境变量：export PATH=$PATH:/usr/local/rabbitmq/sbin执行source /etc/profile让文件生效。#15.设置开启自启脚本chown -R rabbitmq.rabbitmq rabbitmq_server-3.8.5添加 source /etc/profile 否则可能提示erl无法找到vi /usr/local/rabbitmq/sbin/rabbitmq-envsource /etc/profile/usr/local/rabbitmq/var/log/rabbitmq/rabbit@eus-video-compose02.log# cat ~/.erlang.cookie QBISJBZGKYVFNASJQWDQ注意 .erlang.cookie 文件在/home/rabbitmq 下，因通过rabbitmq账户去启动，并且/root/下的 .erlang.cookie值要和/home/rabbitmq 下的文件值保持一致，否则集群无法启动# 启动管理程序
