开放防火墙端口
$ firewall-cmd --zone=public --add-port=5672/tcp --permanent
$ firewall-cmd --zone=public --add-port=15672/tcp --permanent
$ firewall-cmd --zone=public --add-port=25672/tcp --permanent
$ firewall-cmd --zone=public --add-port=4369/tcp --permanent
$ sudo firewall-cmd --reload
方法一：步骤安装
1、创建目录
$ mkdir -p /usr/java
$ cd /usr/java
2、安装erlang
erlang在安装前需要先安装下它的依赖工具:
$ sudo yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC-devel
官网下载 erlang源码包，或者用wget获取：
$ wget http://erlang.org/download/otp_src_21.2.tar.gz
$ tar -xvzf otp_src_21.2.tar.gz
$ cd otp_src_21.2
$ ./configure --prefix=/usr/java/erlang --without-javac
--prefix=/usr/erlang 是说明将当前的安装放在usr/erlang文件夹下。
$ make
$ make install
安装 make install 。安装完成后会有一个erlang文件夹。otp_src_21.2和otp_src_21.2.tar.gz都可以删除了。
测试：$ ./bin/erl
3、配置环境变量
$ sudo vi /etc/profile
# erlang env
export ERLANG_HOME=/usr/java/erlang/
export PATH=$ERLANG_HOME/bin:$PATH
$ source /etc/profile
4、使用编译过的包安装rabbitmq
$ wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.11/rabbitmq-server-generic-unix-3.7.11.tar.xz
$ xz -d rabbitmq-server-generic-unix-3.7.11.tar.xz
$ tar -xvf rabbitmq-server-generic-unix-3.7.11.tar
$ mv rabbitmq_server-3.7.11/ rabbitmq
- 设置环境变量
$ vi /etc/profile
# Rabbitmq Env
export RABBITMQ_HOME=/usr/java/rabbitmq
export PATH=$PATH:${RABBITMQ_HOME}/sbin
$ source /etc/profile
- 配置
在./sbin/rabbitmq-defaults 文件中，CONFIG_FILE变量指定了配置文件的位置，CONF_ENV_FILE指定了rabbitmq-env.conf文件的位置
CONFIG_FILE=/usr/java/rabbitmq/etc/rabbitmq/rabbitmq
CONF_ENV_FILE=/usr/java/rabbitmq/etc/rabbitmq/rabbitmq-env.conf
按照位置创建配置文件：$ touch /usr/java/rabbitmq/etc/rabbitmq/rabbitmq.config
rabbitmq.config内容范例
按照位置创建配置文件：$ touch /usr/java/rabbitmq/etc/rabbitmq/rabbitmq-env.conf
rabbitmq-env.conf内容：
RABBITMQ_MNESIA_BASE=/usr/java/rabbitmq/data
RABBITMQ_LOG_BASE=/usr/java/rabbitmq/logs
$ mkdir -p /usr/java/rabbitmq/data
$ mkdir -p /usr/java/rabbitmq/logs
启动：$ rabbitmq-server
开启web管理插件：$ rabbitmq-plugins enable rabbitmq_management
登录遇到问题：User can only log in via localhost
找到rabbit.app vi /usr/rabbitmq/ebin/rabbit.app
将：{loopback_users, [<<”guest”>>]}，
改为：{loopback_users, []}，
- 添加到服务
脚本见末尾 或 参考
出现问题服务启动不了
$ cat /var/log/rabbitmq/startup_err
[root@centos-100 panqt]# cat /var/log/rabbitmq/startup_err
/usr/java/rabbitmq/sbin/rabbitmq-server:行187: erl: 未找到命令
因为脚本中没有导入erlang环境变量，导入即可
方法二：配置yum源式安装
$ vi /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/21/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1
$ vi /etc/yum.repos.d/rabbitmq-server.repo
[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/
gpgcheck=0
repo_gpgcheck=0
enabled=1
显示可安装的程序包：
$ yum list available rabbitmq-server
$ yum list available erlang
安装：$ yum install -y rabbitmq-server
一个命令就可以把erlang和rabbitmq都安装好
yum源式安装配置：
$ cd /etc/rabbitmq
$ vi rabbitmq-env.conf
RABBITMQ_MNESIA_BASE=/usr/rabbitmq/rabbitmq-server/data
RABBITMQ_LOG_BASE=/usr/rabbitmq/rabbitmq-server/logs
$ mkdir -p /usr/rabbitmq/rabbitmq-server/data
$ mkdir -p /usr/rabbitmq/rabbitmq-server/logs
$ chmod -R 777 /usr/rabbitmq
对于rabbitmq.config配置文件的样本可以在/usr/share/doc/rabbitmq-server/ 或者 /usr/share/doc/rabbitmq-server-3.7.13/里找到，就是一个rabbitmq.config.example的文件，去掉.example即可使用，RabbitMQ平时使用默认配置即可
$ cp /usr/share/doc/rabbitmq-server-3.7.13/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config
然后保存安装下RabbitMQ服务
$ rabbitmq-server install
启动RabbitMQ服务可以通过命令：$ rabbitmq-server start
添加rabbitmq到启动项可以通过命令：$ chkconfig rabbitmq-server on
还有就是开启管理界面可以通过命令：$ rabbitmq-plugins enable rabbitmq_management
访问管理服务：http://192.168.200.100:15672/
出现错误：User can only log in via localhost
