CentOS7下单机部署RabbltMQ环境的操作记录

　　一、RabbitMQ简单介绍
在日常工作环境中，你是否遇到过两个（多个）系统间需要通过定时任务来同步某些数据？你是否在为异构系统的不同进程间相互调用、通讯的问题而苦恼、挣扎？如果是，那么恭喜你，消息服务让你可以很轻松地解决这些问题。消息服务擅长于解决多系统、异构系统间的数据交换（消息通知/通讯）问题，你也可以把它用于系统间服务的相互调用，即适用于云计算集群的远程调用(RPC)。毫无疑问，RabbitMQ就是当前最主流的消息中间件之一。
　　AMQP（Advanced Message Queuing Protocol）即高级消息队列协议，是应用层协议的一个开放标准，为面向消息的中间件设计。消息中间件主要用于组件之间的解耦，消息的发送者无需知道消息使用者的存在，反之亦然。AMQP的主要特征是面向消息、队列、路由（包括点对点和发布/订阅）、可靠性、安全。RabbitMQ是一个开源的AMQP实现，服务器端用Erlang语言编写，支持多种客户端，如：Python、Ruby、.NET、Java、JMS、C、PHP、ActionScript、XMPP、STOMP等，支持AJAX。用于在分布式系统中存储转发消息，在易用性、扩展性、高可用性等方面表现不俗。
　　二、CentOS7下部署RabbitMQ记录



由于RabbitMQ是通过Erlang来开发的，需要需要安装Erlang，然而在安装Erlang的时候又有一大波依赖需要安装，但是郁闷的是这些依赖不在CentOS默认的yum库中。
1）添加Erlang Solutions key 支持
[iyunv@sh-op-mq01 ~]# rpm --import http://binaries.erlang-solutions.com/debian/erlang_solutions.asc
[iyunv@sh-op-mq01 ~]# wget http://binaries.erlang-solutions.com/rpm/centos/erlang_solutions.repo
2）安装Erlang
[iyunv@sh-op-mq01 ~]# yum install epel-release
[iyunv@sh-op-mq01 ~]# yum install erlang
3）安装RabbitMQ
[iyunv@sh-op-mq01 ~]# rpm -ivh  http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.5/rabbitmq-server-3.6.5-1.noarch.rpm
[iyunv@sh-op-mq01 ~]# wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.5/rabbitmq-server-3.6.5-1.noarch.rpm
[iyunv@sh-op-mq01 ~]# rpm -ivh rabbitmq-server-3.6.5-1.noarch.rpm
4）优化配置
[iyunv@sh-op-mq01 ~]# cat /etc/security/limits.conf
.......
* soft nofile 65535
* hard nofile 65535
[iyunv@sh-op-mq01 ~]# ulimit -n
65535
[iyunv@sh-op-mq01 ~]# vim /etc/sysctl.conf       //添加下面一行
fs.file-max = 100000
[iyunv@sh-op-mq01 ~]# sysctl -p
5）启动RabbitMQ
[iyunv@sh-op-mq01 ~]# systemctl enable rabbitmq-server.service
[iyunv@sh-op-mq01 ~]# systemctl start/restart/stop/status rabbitmq-server.service
RabbitMQ默认监听端口是15672
[iyunv@sh-op-mq01 rabbitmq]# lsof -i:15672
COMMAND    PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
beam.smp 12776 rabbitmq   50u  IPv4 582895      0t0  TCP *:15672 (LISTEN)
默认RabbitMQ的安装目录路径是/var/lib/rabbitmq、默认log路径是/var/log/rabbitmq/
[iyunv@sh-op-mq01 ~]# rabbitmqctl --help
[iyunv@sh-op-mq01 ~]# rabbitmqctl status
[iyunv@sh-op-mq01 ~]# rabbitmqctl environment
6) 可以自定义RabbitMQ配置
[iyunv@sh-op-mq01 ~]# cd /etc/rabbitmq/
[iyunv@sh-op-mq01 rabbitmq]# cat rabbitmq-env.conf
LOG_BASE=/data/log/rabbitmq                            //定义RabbitMQ的日志路径
[iyunv@sh-op-mq01 rabbitmq]# mkdir /data/log/rabbitmq
[iyunv@sh-op-mq01 rabbitmq]# chown -R rabbitmq.rabbitmq /data/log/rabbitmq
重启RabbitMQ
[iyunv@sh-op-mq01 rabbitmq]# systemctl restart rabbitmq-server.service
rabbit-server当前状态
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl status

------------------------------------------------------------------------
可以用下面命令安装更新维护插件：
[iyunv@sh-op-mq01 rabbitmq]# rabbitmq-plugins enable rabbitmq_management
[iyunv@sh-op-mq01 rabbitmq]# systemctl restart rabbitmq-server.service
　　在浏览器里输入http://localhost:15672访问RabbitMQ，默认用户名和密码都是guest，若能正常访问和登陆，即说明正常连接RabbitMQ

　　如果使用默认的guest/guest账号密码登陆不上，解决办法如下：



[iyunv@sh-op-mq01 rabbitmq]# vim /etc/rabbitmq/rabbitmq.config
[{rabbit, [{loopback_users, []}]}].
[iyunv@sh-op-mq01 rabbitmq]# systemctl restart rabbitmq-server.service
然后使用guest/guest登陆即可！
--------------------------------------------------------------------------------
如果还是使用guest/guest登陆不上RabbitMQ，可以自己创建了一个账户，赋予管理员权限
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl  add_user  username  password
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl  set_user_tags  username  administrator
创建完后用以下命令查看创建完的账号
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl list_users
删除用户
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl delete_user username
修改密码
[iyunv@sh-op-mq01 rabbitmq]# rabbitmqctl  oldPassword  Username  newPassword
