修改权限

chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
chmod 400 .erlang.cookie

再次运行，成功。

系统环境

操作系统：CentOS6.9

erlang：OTP 19.3

安装步骤

安装erlang

1，安装预环境

通过yum安装以下组件，运行命令：

[root@rabbitmqserver erlang]# yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel

2，下载erlang的源代码文件并解压缩

运行如下命令解压。

[root@rabbitmqserver softwares]# tar -xvf otp_src_19.3.tar.gz

然后，运行如下命令重命名文件夹为erlang。

[root@rabbitmqserver softwares]# mv otp_src_19.3 ./erlang

3，配置安装

首先是./configure，检查编译环境并配置安装路径，运行如下命令：

[root@rabbitmqserver erlang]# ./configure --prefix=/usr/erlang --without-javac

然后，make，对源代码进行编译，运行如下命令：

[root@rabbitmqserver erlang]# make

最后，make install，开始安装，运行如下命令：

[root@rabbitmqserver erlang]# make install

4，设置环境变量

运行以下命令编辑/etc/profile文件。

[root@rabbitmqserver erlang]# vim /etc/profile

在末尾追加以下内容。

保存，然后运行以下命令使环境变量立即生效。

[root@rabbitmqserver erlang]# source /etc/profile

5，验证是否安装成功

运行如下命令，验证erlang是否安装成功。

[root@rabbitmqserver erlang]# erl

安装rabbitmq-server

1，下载rpm包并安装

运行如下命令开始安装rpm包。

[root@rabbitmqserver softwares]# rpm -ivh rabbitmq-server-3.6.12-1.el6.noarch.rpm

可能碰到以下问题：

解决办法：

2，设置环境变量

运行以下命令编辑/etc/profile文件。

[root@rabbitmqserver softwares]# vim /etc/profile

在末尾追加以下内容。

保存，然后运行以下命令使环境变量立即生效。

[root@rabbitmqserver erlang]# source /etc/profile

3，开启Web监控

首先，运行以下命令，开启rabbitmq

[root@rabbitmqserver rabbitmq]# rabbitmq-server

ctrl+c取消进程后，运行以下命令，开启web监控。

[root@rabbitmqserver rabbitmq]# rabbitmq-plugins enable rabbitmq_management

4，启动

开启web监控之后，我们就可以正式启动rabbitmq了。

启动rabbitmq有以下两种方法。

第一种方法是，直接运行rabbitmq-server命令。

但是这种方式，一旦终端退出后，rabbitmq服务就停止了，所以不推荐这么做。

第二种方法是，运行service rabbitmq-server xxx命令。

service rabbitmq-server start #启动

service rabbitmq-server stop #停止

service rabbitmq-server restart #重启

service rabbitmq-server status #查看状态

service rabbitmq-server etc #查看有哪些命令可以使用

同时将rabbitmq-server加入到开机自启动服务中，运行以下命令：

[root@rabbitmqserver bin]# chkconfig rabbitmq-server on

最佳实践是第二种方法。
