由于rabbitmq是基于erlang语言开发的，所以必须先安装erlang。

安装依赖

yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget gtk2-devel binutils-devel
erlang官网

wget https://ghproxy.com/github.com/erlang/otp/releases/download/OTP-24.2.1/otp_src_24.2.1.tar.gz
tar -zxvf /root/opt_src_24.2.1.tar.gz
mv otp_src_24.2.1 /usr/local/
cd /usr/local/otp_src_24.2.1/
mkdir ../erlang/
./configure --prefix=/usr/local/erlang
make install
echo 'export PATH=$PATH:/usr/local/erlang/bin' >> /etc/profile
source /etc/profile

中间可能会出现这个警告，直接忽略

测试

halt().

安装rabbitmq

wget https://ghproxy.com/github.com/rabbitmq/rabbitmq-server/releases/download/v3.9.13/rabbitmq-server-generic-unix-3.9.13.tar.xz
yum install -y xz
xz -d rabbitmq-server-generic-unix-3.9.13.tar.xz 
tar -xvf rabbitmq-server-generic-unix-3.9.13.tar 
mv rabbitmq_server-3.9.13/ /usr/local/
cd /usr/local/
mv rabbitmq_server-3.9.13/ rabbitmq
echo 'export PATH=$PATH:/usr/local/rabbitmq/sbin' >> /etc/profile
source /etc/profile
