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/，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/

[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

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.youkuaiyun.com/luckytanggu/article/details/78542700(https://blog.youkuaiyun.com/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] ...
