RabbitMQ安装：
1、下载rabbitmq安装包：
[root@localhost tools]# wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.0/rabbitmq-server-3.6.0-1.noarch.rpm
2、因为rabbitmq是基于erlang环境的，所以要先安装erlang环境：
输入网址下载otp_src_19.1.tar.gz：http://www.erlang.org/downloads/
3、安装erlang环境:
[root@localhost tools]# tar xf otp_src_19.1.tar.gz
[root@localhost tools]# cd otp_src_19.1
[root@localhost otp_src_19.1]#
在配置erlang之前先安装所需的依赖：
[root@localhost otp_src_19.1]# yum -y install ncurses-devel gcc gcc-c++ unixODBC unixODBC-devel openssl openssl-devel java* ##如果没安装java的话要一起安装
开始配置erlang：
[root@localhost otp_src_19.1]# ./configure --prefix=/usr/local/erlang --enable-smp-support --enable-threads --enable-sctp --enable-kernel-poll --enable-hipe --with-ssl
[root@localhost otp_src_19.1]# make &&make install
4、配置环境变量：
[root@localhost otp_src_19.1]# vim /etc/profile ##在文件的最下面加上如下内容
ERL_HOME=/usr/local/erlang
PATH=$ERL_HOME/bin:$PATH
export ERL_HOME PATH
5、配置完成后测试：
[root@localhost ]# cd /usr/local/erlang/bin/
[root@localhost bin]# ./erl
Erlang/OTP 19 [erts-8.1] [source] [64-bit] [smp:24:24] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V8.1 (abort with ^G)
1>
1> ##进入这个模式算成功，输入halt().退出；
6、安装rabbitmq：
[root@localhost tools]# rpm -ivh --nodeps rabbitmq-server-3.6.0-1.noarch.rpm ##忽略依赖安装rabbitmq的rpm包；
warning: rabbitmq-server-3.6.0-1.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID 056e8e56: NOKEY
Preparing... ########################################### [100%]
1:rabbitmq-server ########################################### [100%]
安装成功；
[root@localhost tools]# /etc/init.d/rabbitmq-server start ##这样直接启动的话会报下面的错；
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
可以的话可以用chkconfig rabbitmq-server on 这条命令加入到开机自启动中去；
[root@localhost tools]# ln -s /usr/local/erlang/bin/erl /usr/bin/erl ##输入这条命令解决上面的错误；
[root@localhost tools]# /etc/init.d/rabbitmq-server start ##在启动一次；
Starting rabbitmq-server: SUCCESS
rabbitmq-server.
检查端口：
[root@localhost tools]# netstat -utpln|grep beam.smp ##出现下面三个算正确；
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 6352/beam.smp
tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 6352/beam.smp
tcp 0 0 :::5672 :::* LISTEN 6352/beam.smp
7、启用维护插件：
[root@localhost tools]# rabbitmq-plugins enable rabbitmq_management ##出现下面的情况就算正确了；
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Applying plugin configuration to rabbit@localhost... started 6 plugins.
8、采用浏览器登录：
http://x.x.x.x:15672/ ##ip加端口的方式；
如果登录成功就算大功告成，如果输入用户名密码不能登录则执行如下操作：
[root@localhost ~]# vim /etc/rabbitmq/rabbitmq.config ##创建一个配置文件，写入下面的内容；
[{rabbit, [{loopback_users, []}]}].
9、基本的用户管理：
新建用户：rabbitmqctl add_user username password
删除用户: rabbitmqctl delete_user username
改密码: rabbimqctl change_password {username} {newpassword}
设置用户角色：rabbitmqctl set_user_tags {username} {tag ...}
遇到的问题：
生产中rabbitmq重启不了，能关闭，但不能启动，解决办法：
[root@localhost rabbitmq]# ps -ef|grep rabbitmq ##查看rabbitmq的所有进程；

通过一系列的kill杀死，总之是全部干掉一个不留；
[root@localhost rabbitmq]# pkill rabbitmq
[root@localhost rabbitmq]# kill -9 4776
[root@localhost rabbitmq]# kill -9 6352
[root@localhost rabbitmq]# netstat -utpln ##端口没有了；
