centos系统下RabbitMQ安装教程

centos系统下RabbitMQ安装教程
我这里的环境用的腾讯云的轻应用环境

RabbitMQ是一个开源的遵循AMQP协议实现的基于Erlang语言编写，即需要先安装部署Erlang环境再安装RabbitMQ环境。需加注意的是，读者若不想跟着我的版本号下载安装，可根据两者版本号的对应表进行下载，安装相应版本的Erlang和RabbitMQ，只需在下文修改命令里面的版本号即可，如下:
一 Erlang下载安装
在确定了RabbitMQ版本号后，先下载安装Erlang环境。

二 RabbitMQ下载安装
下面依旧通过wget命令完成RabbitMQ的下载。

wget --content-disposition https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/7/rabbitmq-server-3.8.13-1.el7.noarch.rpm/download.rpm
1

当你下载完成后，你需要运行下面的命令来将 Key 导入，执行命令：

rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
1

yum安装：

yum localinstall rabbitmq-server-3.8.13-1.el7.noarch.rpm
[root@VM-8-17-centos new]# rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

如此RabbitMQ安装成功就安装成功了，安装完成后，需要启动 rabbitmq 服务器，执行命令：

systemctl start rabbitmq-server
1

设置开机自动启动，执行命令：

systemctl enable rabbitmq-server
1

在目录下启动的命令

/sbin/service rabbitmq-server start  #启动

/sbin/service rabbitmq-server status #状态

/sbin/service rabbitmq-server stop #停止

三 RabbitMQ Web界面管理
默认情况下，是没有安装web端的客户端插件，需要安装才可以生效 。执行命令：

[root@VM-8-17-centos new]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@VM-8-17-centos:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@VM-8-17-centos...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

set 3 plugins.
Offline change; changes will take effect at broker restart.

注意，请在服务器上开放 15672 端口

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

systemctl restart firewalld

新增用户。

[root@VM-8-17-centos new]# rabbitmqctl add_user admin 123456
Adding user "admin" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.

设置用户分配操作权限。

设置 vhost的用户权限

[root@VM-8-17-centos new]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

最后就可以输入IP:15672登录web界面了

总结使用rpm包安装方式是最快捷的一种方式，不过还有源码安装方式，
但是比如 ：erlang环境
wget http://www.erlang.org/download/otp_src_24.0.tar.gz，下载慢如蜗牛
顺便贴下过程，我这里使用otp_src_21.1.tar.gz演示

（1）安装erlang所需要的依赖
1 运行以下命令，安装erlang所需要的依赖

yum install -y make gcc gcc-c++ m4 openssl openssl-devel ncurses-devel unixODBC unixODBC-devel java java-devel
1

2 运行以下命令，下载erlang安装包

wget http://erlang.org/download/otp_src_21.1.tar.gz
1

3 运行以下命令，解压erlang安装包

tar -zxvf otp_src_21.1.tar.gz
1

4 运行以下命令，进入erlang安装包的解压路径，并为erlang创建一个新的目录

cd otp_src_21.1
mkdir -p /usr/local/erlang
1
2

5 依次运行以下命令，编译并安装erlang

./configure --prefix=/usr/local/erlang
make && make install
1
2

6 安装完成后，运行以下命令，为erlang配置环境变量

echo 'export PATH=$PATH:/usr/local/erlang/bin' >> /etc/profile
1

7 运行以下命令，使环境变量立即生效

source /etc/profile
1

8 运行以下命令，返回系统的/root目录，然后查看erlang版本，确认是否安装成功

cd
erl -version
1
2

（2）下载并安装RabbitMQ
RabbitMQ对Erlang的版本具有一定限制，更多信息，请参见RabbitMQ Erlang Version Requirements。本示例使用的Erlang为21.1版本，因此选择下载RabbitMQ 3.7.8版本

1、运行以下命令，下载RabbitMQ安装包

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.8/rabbitmq-server-generic-unix-3.7.8.tar.xz
1

2、运行以下命令，解压RabbitMQ安装包

tar -xvf rabbitmq-server-generic-unix-3.7.8.tar.xz
1

3、解压完成后，运行以下命令，为RabbitMQ配置环境变量

echo 'export PATH=$PATH:/root/rabbitmq_server-3.7.8/sbin' >> /etc/profile
1

4、运行以下命令，使环境变量立即生效

source /etc/profile
1

（3）配置RabbitMQ。
1、运行以下命令，启动RabbitMQ并后台运行

rabbitmq-server -detached
1

注意 该命令只在当前运行的系统环境下启动RabbitMQ，一旦服务器重启，RabbitMQ服务将不会自动启动。因此，建议您通过阿里云的云助手功能，设置RabbitMQ开机自启动。具体操作，请参见通过云助手设置RabbitMQ开机自启动。

2、运行以下命令，启动RabbitMQ监控插件。

rabbitmq-plugins enable rabbitmq_management
1

如果您需要关闭RabbitMQ监控插件，可以运行
rabbitmq-plugins disable rabbitmq_management命令。

3、为保证数据安全，建议您运行以下命令，删除默认用户。

RabbitMQ默认的账号用户名和密码都是guest。

rabbitmqctl delete_user guest
1

4、创建RabbitMQ管理员用户。

a 运行以下命令，创建一个新用户

rabbitmqctl add_user <用户名> <密码>
1

其中，<用户名>和<密码>为您自定义的信息。

b 运行以下命令，将创建的新用户设置为管理员。

rabbitmqctl set_user_tags <用户名> administrator
1

c 运行以下命令，赋予新创建的用户所有权限

rabbitmqctl set_permissions -p / <用户名> ".*" ".*" ".*"
1

（4）配置RabbitMQ的rabbitmq-server文件。

1.1 运行以下命令，编辑rabbitmq-server文件。

vi /root/rabbitmq_server-3.7.8/sbin/rabbitmq-server
1

1.2 按下shift+:组合键，然后输入set nu查看文件的行号。

1.3 按下shift+:组合键，然后输入189跳转至189行。

1.4 按下i键，进入编辑模式

在189行新增以下内容：

export PATH=$PATH:/usr/local/erlang/bin
export HOME=/root/rabbitmq_server-3.7.8/
1
