CentOS 7 安装 RabbitMQ

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
