Rabbitmq的安装

1.上传资源

注意：rabbitmq的版本必须与erlang编译器的版本适配

2.安装依赖环境

//打开虚拟机
yum install build-essential openssl openssl-devel unixODBC unixODBC-devel make gcc gcc-c++ kernel-devel m4 ncurses-devel tk tc xz

3.安装erlang

rpm -ivh erlang-18.3-1.el7.centos.x86_64.rpm

可能会出现以下的错误信息

说明gblic版本太低了，我们可以查看当前的gblic版本，这里需要2.15的版本，所以要进行更新升级

//查看当前的gblic的版本
strings /lib64/libc.so.6 | grep GLIBC

//更新安装依赖sudo yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y

//更新或安装新的glibc组件。

4.安装rabbitmq

//安装之前需要安装一个socat环境，即前面上传的资源
rpm -ivh socat-1.7.3.2-5.el7.lux.x86_64.rpm

如果出现以下错误，需要下载一个依赖包
tcp_wrappers 被 socat-1.7.3.2-1.1.el7.x86_64 需要

//下载包
yum install tcp_wrappers
//验证是否安装成功
rpm -q tcp_wrappers
//完成后再安装socat

//安装rabbitmq
rpm -ivh rabbitmq-server-3.6.5-1.noarch.rpm

5.rabbitmq的命令

运行mq的时候，出现以下错误

Starting rabbitmq-server (via systemctl): Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.
解决方案：
解决办法：

禁用 SELinux ，修改 /etc/selinux/config
SELINUX=disabled
修改后重启系统，重启系统，reboot

如果还是出现同样的情况的话，继续进行修改

进入文件进行编辑， vi /etc/hosts
按i编辑：
修改为：
主机ip enen enen.com
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6按esc退出编辑，按:wq保存并退出

设置配置文件

cd /usr/share/doc/rabbitmq-server-3.6.5/cp rabbitmq.config.example /etc/rabbitmq/rabbitmq.config

访问rabbitmq页面，RabbitMQ在安装好后，可以访问http://ip地址:15672 ；其自带了guest/guest的用户名和密码，3.以上的版本就必须自己创建用户了；如果需要创建自定义用户；那么也可以登录管理界面后，如下操作

//自创建用户的步骤
rabbitmqctl  add_user  admin  admin //创建用户	
rabbitmqctl  set_user_tags  admin administrator //设置权限 
service rabbitmq-server restart//重启服务
