• Centos7安装RabbitMQ


    安装erlang

    1.配置

    wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
    rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
    rpm --import https://packages.erlang-solutions.com/rpm/erlang_solutions.asc
    如果报错:error: Failed dependencies: epel-release is needed by erlang-solutions-1.0-1.noarch
    缺少依赖:
    yum install epel-release

    内容:

    /etc/yum.repos.d/erlang_solutions.repo
    [erlang-solutions]
    name=Centos $releasever - $basearch - Erlang Solutions
    baseurl=https://packages.erlang-solutions.com/rpm/centos/$releasever/$basearch
    gpgcheck=1
    gpgkey=https://packages.erlang-solutions.com/rpm/erlang_solutions.asc
    enabled=1

    2.安装

    sudo yum install erlang

    sudo yum install esl-erlang

    3.查看

    erl   //Erlang/OTP 22 [erts-10.5.5] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe] .....
    q().

     安装前最好先确认一下源的版本,用阿里云的默认的安装了老版本,不支持最新的MQ

    处理方法:

    yum remove erlang-erts-R16B-03.18.el7.x86_64    //卸载老版本再进行安装

     安装RabbitMQ

    1.配置&安装

    wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.9.5/rabbitmq-server-3.9.5-1.el8.noarch.rpm
    rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
    yum install rabbitmq-server-3.9.5-1.el8.noarch.rpm

    2.启动

    /sbin/service rabbitmq-server start

    遇到一个问题:Protocol 'inet_tcp': register/listen error: etimedout

    防火墙问题: 先关闭防火墙(service iptables stop),就可以启动服务。后面将端口号加入防火墙中,重新打开防火墙。服务正常启动。

    iptables -I INPUT -p tcp --dport 5672 -j ACCEPT
    iptables -I INPUT -p tcp --dport 15672 -j ACCEPT

    3.配置

    rabbitmq-plugins enable rabbitmq_management                   //开启RabbitMQ控制台
    rabbitmqctl add_user admin 123456                             //创建用户
    rabbitmqctl  set_permissions -p "/" admin '.*' '.*' '.*'      //给用户授权
    rabbitmqctl set_user_tags admin administrator                 //给用户赋予administrator角色

     命令:

    rabbitmqctl status     //查看运行状态
    rabbitmqctl stop     //关闭服务
    rabbitmqctl start_app   //启动服务
    service rabbitmq-server start //启动服务
    rabbitmqctl list_users   //列出用户

    访问http://ip:15672  RabbitMQ控制台

    插件:

    yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC-devel

    问题:

    1.unable to perform an operation on node  都说是在hosts文件中加入IP和机器名称,弄了好久都启动不了,后来忙了两天回来再弄的时候竟然可以启动了。多次尝试发现service rabbitmq-server start可以正常启动,用rabbitmqctl start_app会报错,不知是什么原因。

    卸载:

    yum list | grep rabbitmq
    yum -y remove rabbitmq-server.noarch
