    摘要: 今天教大家利用镜像快熟部署使用RabbitMQ。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,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。

    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。
     
    部署方式
    在阿里云服务器下部署 RabbitMQ提供两种部署方式:
    • RabbitMQ镜像部署
    • 手动部署(源码编译安装/YUM安装)
    一般推荐镜像部署适合新手使用更加快捷方便,安装包部署以及手动部署适合对Linux命令有基本了解的用户,可以满足用户个性化部署的要求。本教程主要介绍镜像和手工部署的方式。
     
    镜像部署
    1. 单击 JAVA环境(CentOS7.2 Nginx Tomcat8 JDK)进入镜像详情页。
    JAVA环境(CentOS7.3 Nginx Tomcat8 JDK)
    镜像集成CentOS7.3+Nginx+MySQL5.7+Tomcat8,Nginx动静分离,Tomcat以apr模式运行处理动态资源,大幅度的提高性能,Let's Encrypt一键设置虚拟主机

    2. 单击 **立即购买**,按提示步骤购买 ECS 实例。
    3. 登录 ECS 管理控制台:https://ecs.console.aliyun.com/#/home
    4. 在左边导航栏里,单击 **实例**,进入 ECS 实例列表页。
    5. 选择所购 ECS 实例所在的地域,并找到所购 ECS 实例,在 **IP 地址** 列获取该实例的公网 IP 地址。
    6. 在浏览器地址栏中输入公网 IP 地址,下载操作文档。

    7. 使用putty登录Linux服务器,参考《连接Linux实例》;忘记root密码参考《重置实例密码》。
    8. 使用winscp工具将Java代码放入/data/wwwroot/default中。

    9. 默认tomcat是以一般www用户运行,将网站代码权限改为www,执行下面命令:
    chown -R www.www /data/wwwroot

    手工部署
    系统平台:CentOS 7.3
    rabbitmq版本:rabbitmq-server -3.6.9
    erlang版本:erlang19.3
    JDK版本:JDK1.8.0_121
    • 前提准备
    创建一般用户rabbitmq,运行rabbitmq
    useradd rabbitmq
    设置Linux主机名
    centos7修改/etc/hostname,centos6修改/etc/sysconfig/network,下面以centos7为例
    echo rabbit1 > /etc/hostname
    hostname rabbit1
    exit  #退出重新登录

    安装依赖包
    yum -y install make gcc gcc-c++ m4 ncurses-devel openssl-devel unixODBC-devel
    快速部署rabbitMQ教程
    • 源代码下载
    wget http://erlang.org/download/otp_src_19.3.tar.gz
    wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.9/rabbitmq-server-generic-unix-3.6.9.tar.xz
    • 安装Erlang
    tar xzf otp_src_19.3.tar.gz  #解压
    cd otp_src_19.3
    ./configure --prefix=/usr/local/erlang --enable-shared-zlib --with-ssl --enable-threads --enable-smp-support --enable-kernel-poll --enable-hipe --without-javac
    make && make install
    • 解压RabbitMQ
    1. 解压rabbitmq-server-generic-unix-3.6.9.tar.xz
    tar xvJf rabbitmq-server-generic-unix-3.6.9.tar.xz
    mv rabbitmq_server-3.6.9  /usr/local/rabbitmq
    2. rabbitmq环境变量配置
    sed -i 's@^ERL_DIR=.*@ERL_DIR=/usr/local/erlang/bin/@' /usr/local/rabbitmq/sbin/rabbitmq-defaults
    sed -i 's@^LOG_BASE=.*@LOG_BASE=/usr/local/rabbitmq/var/log/rabbitmq@' /usr/local/rabbitmq/sbin/rabbitmq-defaults
    mkdir -p /usr/local/rabbitmq/var/{lib,log}/rabbitmq
    3. 一般用户(rabbitmq)运行RabbitMQ
    wget http://pkgs.fedoraproject.org/cgit/rpms/rabbitmq-server.git/plain/rabbitmq-script-wrapper
    sed -i 's@cd /var/lib/rabbitmq@cd /usr/local/rabbitmq/var/lib/rabbitmq@g' rabbitmq-script-wrapper  #更改rabbitmq数据存储目录
    sed -i 's@/usr/lib/rabbitmq/bin/@/usr/local/rabbitmq/sbin/@g' rabbitmq-script-wrapper
    chmod +x rabbitmq-script-wrapper
    cp rabbitmq-script-wrapper /usr/sbin/rabbitmqctl
    cp rabbitmq-script-wrapper /usr/sbin/rabbitmq-server
    cp rabbitmq-script-wrapper /usr/sbin/rabbitmq-plugins
    chown -R rabbitmq.rabbitmq /usr/local/rabbitmq/var
    4. rabbitmq日志割接
    cat >> /etc/logrotate.d/rabbitmq-server << EOF
    /usr/local/rabbitmq/var/log/rabbitmq/*.log {
      weekly
      missingok
      rotate 20
      compress
      delaycompress
      notifempty
      sharedscripts
      postrotate
        /sbin/service rabbitmq-server rotate-logs > /dev/null
      endscript
    }
    EOF
    5. rabbitmq启动脚本
    vi /etc/init.d/rabbitmq-server
    #!/bin/sh

    保存后,添加执行权限,并设置自启动
    chmod +x /etc/init.d/rabbitmq-server
    chkconfig --add rabbitmq-server
    chkconfig rabbitmq-server on
    6. 修改rabbitmq.config
    特别注意默认用户名密码,请自行修改default_user,default_pass,loopback_users
    cat > /usr/local/rabbitmq/etc/rabbitmq/rabbitmq.config << EOF
    [
      {rabbit, [
        {tcp_listeners,[{"0.0.0.0",5672}]},
        {tcp_listen_options, [binary, {packet,raw},
                                      {reuseaddr,true},
                                      {backlog,128},
                                      {nodelay,true},
                                      {exit_on_close,false},
                                      {keepalive,true}]},
        {default_vhost,       <<"/">>},
        {default_user,        <<"guest">>},
        {default_pass,        <<"guest">>},
        {loopback_users, ["guest"]},
        {default_permissions, [<<".*">>, <<".*">>, <<".*">>]}
      ]}  
    ]. 
    EOF
    7. 开启rabbitmq manager
    cat > /usr/local/rabbitmq/etc/rabbitmq/enabled_plugins << EOF
    [rabbitmq_management].
    EOF
    8. 启动rabbitmq
    service rabbitmq-server start
    9. 进入管理页面
    浏览器访问http://公网IP:15672
