rabbitmq在centos7上面的安装与使用

1.环境介绍

    系统：Centos7.0

    依赖软件：socat、erlang(有版本限制，到以下地址下载对应的版本：http://www.rabbitmq.com/releases/erlang/)

2.安装介绍

    首先我在http://www.rabbitmq.com/install-rpm.html这个地址下载了一个版本的rabbitmq安装包，通过以下命令安装：    

rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm

    然后告诉我缺少依赖库erlang（http://www.rabbitmq.com/releases/erlang/）和 socat（http://www.rpmfind.net/linux/rpm2html/search.php?query=socat(x86-64)），我在上面对应的地址上下载了软件按安装包，在下载erlang的时候有个小插曲，比较坑，在的官网上面我找了下对应的安装包，结果没有对应的linux的版本，上网查了下说是没有linux的直接的安装包，我就直接下来的otp源码，在linux中编译，下一篇我介绍一下源码的编译方式和安装方式，放在这篇的话就跑题了。

    输入下面的命令开始安装上面的安装包：

rpm -ivh erlang-19.0.4-1.el7.centos.x86_64.rpm

yum install socat

   上面的依赖环境安装好之后就开始安装rabbitmq了

rpm -ivh rabbitmq-server-3.7.4-1.el7.noarch.rpm

    安装很顺利！！

    开始启动rabbitmq服务

systemctl start rabbitmq-server//启动服务
systemctl status rabbitmq-server//查看服务状态

    启动完成后我通过localhost:15672访问rabbit的管理界面是不能访问的。用下面的命令看了下rabbit的状态

    看下面的listeners没有监听15672端口，我判断我的rabbitmq的服务没有开启网页的服务，输入下面的命令安装

rabbitmq-plugins enable rabbitmq_management

rabbitmqctl start_app

systemctl restart rabbitmq-server//重启服务

       查看rabbit的状态，已经开始监听15672端口了，然后我通过下面的地址访问：localhost:15672就可以访问rabbit的图形管理界面了，然后我通过远程主机链接rabbit的图形管理界面，通过guest账户链接，拒绝访问，说是guest只能在本机访问，这个也有道理，所有的rabbit的guest都是默认账户，如果可以通过远程主机连接，这样不太安全。但是我还是想通过远程主机用guest账户访问，从网上查了下，一次按照下面的操作就可以了。

cd /etc/rabbitmq/

vim rabbitmq.config//在这个文件中输入下面的内容保存

[{rabbit, [{loopback_users, []}]}].

rabbitmqctl start_app

systemctl restart rabbitmq-server//重启服务

    好啦，可以用了！！！！！

    然后就可以开始使用了。

附录：管理命令

1.启动服务

systemctl start rabbitmq-server
service rabbitmq-server start//这两个都行

2.用户管理

      新建用户：rabbitmqctl add_user xxxpwd

      删除用户:   rabbitmqctl delete_user xxx

      改密码: rabbimqctl change_password {username} {newpassword}

      设置用户角色：rabbitmqctl set_user_tags {username} {tag ...}

              Tag可以为 administrator,monitoring, management

3.获取服务器状态

服务器状态：rabbitmqctl status

       队列信息：rabbitmqctl list_queues[-p vhostpath] [queueinfoitem ...]

                Queueinfoitem可以为：name，durable，auto_delete，arguments，messages_ready，

                messages_unacknowledged，messages，consumers，memory

       Exchange信息：rabbitmqctllist_exchanges[-p vhostpath] [exchangeinfoitem ...]

                 Exchangeinfoitem有：name，type，durable，auto_delete，internal，arguments.

       Binding信息：rabbitmqctllist_bindings[-p vhostpath] [bindinginfoitem ...]       

                 Bindinginfoitem有：source_name，source_kind，destination_name，destination_kind，routing_key，arguments

       Connection信息：rabbitmqctllist_connections [connectioninfoitem ...]

       Connectioninfoitem有：recv_oct，recv_cnt，send_oct，send_cnt，send_pend等。

       Channel信息：rabbitmqctl  list_channels[channelinfoitem ...]

      Channelinfoitem有consumer_count，messages_unacknowledged，messages_uncommitted，acks_uncommitted，messages_unconfirmed，prefetch_count，client_flow_blocked

好啦，介绍完了，下篇我写下erlang
