rabbitmq notes

安装

系统:CentOS 6 环境: rabbitmq 依赖的Erlang环境包

wget https://www.rabbitmq.com/releases/erlang/erlang-18.1-1.el6.x86_64.rpm

Server:rabbitmq-server安装包

wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.5.7/rabbitmq-server-3.5.7-1.noarch.rpm

配置

插件:启用web管理界面插件:

rabbitmq-plugins enable rabbitmq_management

添加用户,设置用户为管理员以登录web管理界面:

rabbitmqctl add_user {username} {password}

设置用户为管理员:

rabbitmqctl set_user_tags {username} administrator

添加vhost:

rabbitmqctl add_vhost test //rabbitmq 设置的vhost名称不用带斜杠/

设置用户对vhost的权限:

rabbitmqctl set_permissions -p myvhost tonyg "^tonyg-.*" ".*" ".*"

rabbitmqctl参考:rabbitmqctl Doc

运行时辅助命令

查看端口占用情况

netstat -a |grep 15672

查看哪个应用占用了该端口

lsof -i:15672

防火墙开通指定端口

/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/etc/rc.d/init.d/iptables save

关闭防火墙

service iptables stop

windows服务作为消费端

创建服务的命令

sc create ServiceA displayname= "ServiceA_DisplayName" binPath= "/path/to/exe" start= auto
sc start ServiceA

rabbitmq配置格式

amqp://gqc:gqc@10.16.35.92/gqc_host

CentOS辅助相关

centos 添加epel库

yum install epel-release
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

centos 安装python pip

yum install python-pip

rabbitmq 配置集群

主节点所在服务器开放4369端口,开放25672端口

从节点添加hosts解析主节点的计算机名

vim /etc/hosts
+10.16.35.92 rabbitmqServer

从节点执行

rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@rabbitmqServer
rabbitmqctl start_app

rabbitmq 集群特性

  1. 除队列外,其他元素全部自动镜像,队列默认持久化但不镜像(所在节点挂了则该队列内数据就下线了,节点恢复则原数据重新恢复上线),需要配置policy
  2. 当队列需要高可用时,需要配置policy,启用队列的镜像和自动同步,可设置ha-sync-batch-size以提高队列性能,可设置queue-master-locator策略

policy设置范例(gqc_host中所有队列启用高可用,自动在所有节点上镜像并自动同步)

Virtual Host    :   gqc_host
Name            :   ha-all
Pattern         :   .*
Apply to        :   queues
Definition      :   ha-mode:all  ha-sync-mode:automatic
Priority        :   0

追记CentOS7安装步骤

  • wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.9/rabbitmq-server-3.6.9-1.el7.noarch.rpm
  • yum install erlang
  • rpm –import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
  • yum install rabbitmq-server-3.6.9-1.el7.noarch.rpm
  • systemctl enable rabbitmq-server.service
  • systemctl start rabbitmq-server
  • rabbitmq 配置web管理界面插件、添加用户、添加vhost等
  • systemctl edit rabbitmq-server 配置LimitNOFILE放开文件描述符限制

systemctl edit rabbitmq-server 输入范例:

[Service]
LimitNOFILE=32768

CentOS7防火墙firewalld管理

firewall-cmd --zone=public --add-port=15672/tcp --permanent
firewall-cmd --zone=public --add-port=5672/tcp --permanent
firewall-cmd --reload

CentOS7服务管理

systemctl list-unit-files|grep rabbitmq
systemctl enable rabbitmq-server.service
systemctl edit rabbitmq-server 服务配置(放开文件描述符限制)
