centos7安装rabbitMq教程

一、安装前的准备

在开始安装RabbitMQ之前，我们需要做一些准备工作，我们需要确保我们的系统满足RabbitMQ的安装要求，我们需要下载并解压RabbitMQ的安装包，我们需要配置RabbitMQ的环境变量。

1、系统要求

RabbitMQ支持多种操作系统，包括Linux、Windows和Mac OS，在CentOS 7上安装RabbitMQ，我们需要确保系统满足以下要求：

操作系统：CentOS 7

内存：至少1GB

硬盘空间：至少5GB

网络：支持TCP/IP协议

2、下载RabbitMQ安装包

我们可以从RabbitMQ的官方网站下载最新的安装包，在CentOS 7上，我们可以选择下载适用于x86_64系统的安装包，下载完成后，我们将安装包解压到我们想要安装RabbitMQ的目录。

3、配置环境变量

为了方便我们在任何地方都能使用RabbitMQ，我们需要配置环境变量，我们可以将RabbitMQ的bin目录添加到PATH环境变量中。

二、安装RabbitMQ

在完成安装前的准备后，我们就可以开始安装RabbitMQ了，我们可以使用以下步骤来安装RabbitMQ：

1、创建Erlang用户和组

RabbitMQ是基于Erlang开发的，所以我们需要创建一个Erlang用户和组，我们可以使用以下命令来创建Erlang用户和组：

“`bash

sudo groupadd otp

sudo useradd g otp m rabbitmq

sudo passwd rabbitmq

“`

2、下载Erlang

我们需要下载Erlang的最新版本，并将其解压到/usr/local/erlang目录，我们可以使用以下命令来下载Erlang：

“`bash

wget http://erlang.org/download/otp_src_23.0.tar.gz

tar zxvf otp_src_23.0.tar.gz C /usr/local/erlang

cd /usr/local/erlang/otp_src_23.0/

“`

3、编译和安装Erlang

我们可以使用以下命令来编译和安装Erlang：

“`bash

./configure prefix=/usr/local/erlang enablesmpsupport enablethreads enablekernelpoll enablehipe enablewx withssl=/usr/local/ssl withsslinclude=/usr/local/ssl/include withssllib=/usr/local/ssl/lib withkerlhome=/usr/local/erlang withbootroot=/usr/local/erlang withtermcap=linux disablemanuallyinstallederts prefix=/usr/local/erlang withoutjavac withoutjava withoutsnmp withoutinets withoutodbc withouttools withoutgraphics withoutwebtool withoutreltool withoutsyntaxtools withoutmegaco withoutamqp withoutreltool withoutopenssl withoutnativelibs disabledynamicssllib

make && make install

“`

4、添加Erlang用户到rabbitmq用户组

我们需要将Erlang用户添加到rabbitmq用户组，以便rabbitmq用户可以运行Erlang程序，我们可以使用以下命令来添加Erlang用户到rabbitmq用户组：

“`bash

sudo gpasswd a rabbitmq otp

“`

5、设置环境变量

我们需要设置ERLANG_HOME和PATH环境变量，以便系统能找到Erlang和RabbitMQ的可执行文件，我们可以使用以下命令来设置环境变量：

“`bash

echo ‘export ERLANG_HOME=/usr/local/erlang’ >> ~rabbitmq/.bashrc

echo ‘export PATH=$ERLANG_HOME/bin:$PATH’ >> ~rabbitmq/.bashrc

source ~rabbitmq/.bashrc

“`

6、安装RabbitMQ

我们可以使用以下命令来安装RabbitMQ：

“`bash

sudo yum install y rabbitmqserver rabbitmqserverplugins rabbitmqclients rabbitmqdevel epelrelease python2pip python34 python34pip python34devel openssl openssldevel wget socat postgresql
