# RabbitMQ 安装 #

## 安装 Erlang ##

> 因为RabbitMQ是由Erlang语言编写的，所以，需要安装Erlang，Erlang安装方式有很多种，此处仅介绍使用源码包安装的方式。

首先前往Erlang官网[http://www.erlang.org/downloads/][http_www.erlang.org_downloads]，选择`OTP 21.0 Source File`进行下载。

将安装文件拷贝至linux系统中，当然你也可以在linux系统中直接使用`wget`命令下载软件包，接着执行以下命令即可：

[root@localhost home]# wget http://erlang.org/download/otp_src_21.0.tar.gz
    [root@localhost home]# tar -zxvf otp_src_21.0.tar.gz
    [root@localhost home]# cd otp_src_21.0
    [root@localhost otp_src_21.0]# ./configure --prefix=/opt/erlang

因为erlang要依赖`ncurses`，所以此时可能会报如下错误：

No curses library functions found

这是安装一下`ncurses`即可：

[root@localhost otp_src_21.0]# yum install ncurses-devel
    [root@localhost otp_src_21.0]# make
    [root@localhost otp_src_21.0]# make install

当然安装过程中，可能还会出现其他包找不到的情况，此时只要根据提示安装相应的包即可。

**注：**  
如果你是`Windows`，请选择对于的软件包进行下载，然后执行exe文件即可。

## 安装RabbitMQ ##

> RabbitMQ安装方式较为简单，本文主要介绍源码安装方式

首先访问官网下载源码包：[http://www.rabbitmq.com/releases/rabbitmq-server/][http_www.rabbitmq.com_releases_rabbitmq-server]

[root@localhost home]# wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/rabbitmq-server-generic-unix-3.6.15.tar.xz
    [root@localhost home]# xz -d rabbitmq-server-generic-unix-3.6.15.tar.xz
    [root@localhost home]# tar -xvf rabbitmq-server-generic-unix-3.6.15.tar

配置环境变量

[root@localhost home]# vim /etc/profile
    
    export RABBITMQ_HOME=/usr/local/rabbitmq_server-3.6.15
    export PATH=$PATH:$RABBITMQ_HOME/sbin
    
    [root@localhost home]# source /etc/profile

启动RabbitMQ:

rabbitmq-server -detached

\-detached 的主要作用是为了能够让RabbitMQ服务以守护进程的方式在后台运行。

使用rabbitmqctl status，如果看见一下内容，则说明启动成功：

[root@rabbitmq ~]# rabbitmqctl status
    Status of node rabbit@rabbitmq
    [{pid,3556},
     {running_applications,
         [{rabbitmq_management,"RabbitMQ Management Console","3.6.15"},

## RabbitMQ 启动问题 ##

第一次安装RabbitMQ后，不论是用rabbitmqctl status命令，还是使用rabbitmqctl add 命令都会出现如下错误：

rabbitmq Error: unable to connect to node XXX@XXX: nodedown

针对这个问题。网上有很多解决办法。但是基本都说是Erlang的cookie，但是这是windows下的问题。其解决办法为：

检查C:\\Windows.erlang.cookie 及 C:\\用户\\你的用户名.erlang.cookie。检查两个文件内容是否一致，不一致用其中一个替换另一个即可。

最后在网上找到一篇关于linux的解决办法。其源地址为:\[[https://blog.csdn.net/luckytanggu/article/details/78542700(https://blog.csdn.net/luckytanggu/article/details/78542700)][https_blog.csdn.net_luckytanggu_article_details_78542700_https_blog.csdn.net_luckytanggu_article_details_78542700]

内容如下：

#先把rabbitmq进程杀掉
    [root@localhost home] ps -ef | grep rabbitmq | grep -v grep | awk '{print $2}' | xargs kill -9
    
    #设置hostname(假设主机ip为：192.168.1.1，主机名设为：mq)
    [root@localhost home] echo 192.168.1.1 mq > /etc/hosts
    [root@localhost home] echo rabbitmq > /etc/hostname
    [root@localhost home] export HOSTNAME=mq

重启电脑后，RabbitMQ访问正常

## 添加管理员 ##

> 默认情况下，访问RabbitMQ服务的用户名和密码都是guest，但是这个账户只能通过本地网络(localhost)进行访问，远程访问受限，所以需要添加为其添加一个用户。

首先启动RabbitMQ，然后添加用户

[root@localhost home]# rabbitmqctl add user root root
    Creating user "root"...
    #为root 用户设置所有权限:
    [root@localhost home]# rabbitmqctl set_permissions -p / root ".*" ".*" ".*"
    Setting permissions for user "root" in vhost "/"...
    #设置rott为管理员
    [root@localhost home] rabbitmqctl set user_tags root administrator
    Setting tags for user "root" to [administrator] ...

## 开放网页控制台 ##

执行`rabbitmq-plugins enable rabbitmq_management`开启web管理界面
