RabbitMQ安装
1 安装erlang
下载地址:http://www.erlang.org/downloads
博主这里采用的是otp_src_19.1.tar.gz (200MB+)
[root@hidden util]# tar zxvf otp_src_19.1.tar.gz
[root@hidden util]# cd otp_src_19.1
[root@hidden otp_src_19.1]# ./configure --prefix=/opt/erlang
[root@hidden otp_src_19.1]# make
[root@hidden otp_src_19.1]# make install

修改/etc/profile文件,添加下面的环境变量:
ERLANG_HOME=/opt/erlang
export PATH=$PATH:$ERLANG_HOME/bin
export ERLANG_HOME

最后执行source /etc/profile让文件生效。
2 安装simpleJson
下载地址:https://pypi.python.org/pypi/simplejson/
博主这里采用的是simplejson-3.10.0.tar.gz
[root@hidden util]# tar zxvf simplejson-3.10.0.tar.gz
[root@hidden util]# cd simplejson-3.10.0
[root@hidden simplejson-3.10.0]# python setup.py install

3 安装rabbitmq
下载地址:http://www.rabbitmq.com/releases/rabbitmq-server/
博主这里用的版本就有很多了,比如2.7.0, 3.4.0, 3.4.1, 3.4.2, 3.4.3, 3.5.7, 3.6.0等等,不过都是用的rabbitmq-server-generic-unix-..*.tar.gz的版本。
这里以3.5.7举例:
[root@hidden util]# tar zvxf rabbitmq-server-generic-unix-3.5.7.tar.gz -C /opt
[root@hidden util]# cd /opt
[root@hidden util]# mv rabbitmq_server-3.5.7 rabbitmq

修改/etc/profile文件,添加下面的环境变量:
export PATH=$PATH:/opt/rabbitmq/sbin
- 1
最后执行source /etc/profile让文件生效。
运行:rabbitmq-server -detached
之后运行rabbitmqctl status查看rabbitmq是否正常启动:
[root@zhuzhonghua2-fqawb rabbitmq]# rabbitmqctl status
Status of node 'rabbit@zhuzhonghua2-fqawb' ...

RabbitMQ集群搭建方法
这里展示的是多机集群的部署,如果机器受限,可以选择单机集群部署,详细可以参考《RabbitMQ单机多实例配置》。
这里选用三台主机,主机名分别是hidden1, hidden2, hidden3
1 在这三台机器中安装rabbitmq-server, 参考上面。
2 读取其中一个节点的cookie, 并复制到其他节点(节点之间通过cookie确定相互是否可通信)。
cookie存放在/var/lib/rabbitmq/.erlang.cookie或者$HOME/.erlang.cookie中。
3 逐个启动节点 rabbitmq-server -detached
4 查看各节点的状态: rabbitmqctl status, rabbitmqctl cluster_status
5 配置各节点的hosts文件( vim /etc/hosts)
xxx.xxx.xxx.xxx hidden1
xxx.xxx.xxx.xxx hidden2
xxx.xxx.xxx.xxx hidden3
6 建立集群
以hidden1为主节点,在hidden2上:
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@hidden1
rabbitmqctl start_app
hidden3上的操作与hidden2的雷同。
最后通过rabbitmqctl cluster_status查看集群的状态信息:
[{nodes,[{disc,[rabbit@hidden1,'rabbit@hidden2','rabbit@hidden3']}]},
{running_nodes,[rabbit@hidden1,'rabbit@hidden2','rabbit@hidden3']},
{cluster_name,<<"rabbit@hidden1">>},
{partitions,[]}]

7 在访问web(http://xxx.xxx.xxx.xxx:15672)时, 如果在Overview中的Nodes部分看到“Node statistics not available”的信息,说明在该节点上web管理插件还未启用。直接运行rabbitmq-plugins enable rabbitmq_management即可。
