一、Centos中安装erlang
1、下载最新erlang19 http://erlang.org/download/otp_src_19.0.tar.gz
2、用winscp工具上传至/usr/local/src目录下，进入目录下
# cd /usr/local/src
# tar -zxvf otp_src_19.0.tar.gz -C ../ 解压至上级目录
# cd ../otp_src_19.0
3、安装依赖
# yum install ncurses ncurses-base ncurses-devel ncurses-libs ncurses-static ncurses-term ocaml-curses ocaml-curses-devel -y
# yum install openssl-devel zlib-devel -y
# yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel perl
# yum -y install ncurses-devel
# yum install ncurses-devel
# yum list|grep ncurses
# yum -y install ncurses-devel
# yum install ncurses-devel
4、编译
# ./configure -h #执行帮助
# ./configure --prefix=/usr/local/erlang --with-ssl -enable-threads -enable-smmp-support -enable-kernel-poll --enable-hipe --without-javac #不用java编译，故去掉java避免错误
5、安装
# make & make install
6、修改环境变量
# vim /etc/profile
# export ERLANG_HOME=/usr/local/erlang
# export PATH=$ERLANG_HOME/bin:$PATH
# source /etc/profile
7、测试是否安装成功
# erl #如果成功会返回erl的版本号18
二、Centos中安装rabbitmq3.6.5
1、下载RabbitMQ3.6.5
# cd /usr/local/src
#wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.5/rabbitmq-server-generic-unix-3.6.5.tar.xz
# tar xvJf rabbitmq-server-generic-unix-3.6.5.tar.xz
# mv rabbitmq_server-3.6.5 ../
# cd /usr/local/rabbitmq_server-3.6.5/sbin
# ./rabbitmq_server -detached 后台启动rabbitmq_server
# ./rabbitmq-plugins enable rabbitmq_management 开启插件管理页面，需要重启rabbitmq
# ./rabbitmqctl stop 停止服务
# ./rabbitmq_server -detached
默认rabbitmq是禁止远程用户访问的，需要开启(可以网上查询)
# ./rabbitmqctl add_user admin admin
# ./rabbitmqctl list_users
# ./rabbitmqctl set_user_tags admin administrator
# ./rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
安装完成之后，需要开启5672 15672端口供客户端访问
# vi /etc/sysconfig/iptables
# -A INPUT -m state –state NEW -m tcp -p tcp –dport 5672 -j ACCEPT
# -A INPUT -m state –state NEW -m tcp -p tcp –dport 15672 -j ACCEPT
# service iptables restart
可以输入http://ip:15672 输入用户名admin密码为admin，进行访问

问题：
安装完rabbitmq-server，重启时间很长，并且报错ERROR: epmd error for host "yourhostname": timeout 原因是：主机名和ip不匹配，需要更改hostname或者/etc/hosts文件 修改主机名：#hostname yourhostname 要跟/etc/hosts /etc/sysconfig/network 文件中一致。
