实验前提

该实验基于VMwareworkstation 17.0。
使用发行版本为centos7，最小化安装。
环境中使用两台虚拟机，双网卡配置。
密码规划：本实验所有密码皆使用redhat
本实验基于模板机搭建，如果有基础的朋友，可以选择自己创建
实验使用远程连接软件MobaXterm

实验规划

主机名	IP-外网	IP-内网	角色	配置
control	192.168.96.20	192.168.113.20	控制节点	8G+4核
compute	192.168.96.21	192.168.113.21	计算节点	8G+4核

创建模板机

时区选择上海

磁盘分区采用自动分区

安装选用最小化安装

关闭防火墙

关闭selinux

[root@localhost ~]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disbaled #将此行修改为disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

清除machine-id

[root@localhost ~]# echo "" > /etc/machine-id

Bash

清除网卡配置文件

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# vi ifcfg-ens32

BOOTPROTO="dhcp"
DEFROUTE="yes"

关机并克隆

[root@localhost network-scripts]# init 0

建议在关机后拍个快照，以免以后误触

关机后，将模板机克隆成control和compute机器

系统环境配置

给虚拟机添加第二张网卡后开机，并且将网络适配器2设置为仅主机模式

修改用户名

GATEWAY=192.168.96.2

Bash

进入/etc/sysconfig/network-scripts后

如果遇到没有新添加网卡的配置文件的情况，直接将原本网卡复制并修改为新网卡名即可，可以手动修改参数

[root@control network-scripts]# cp ifcfg-ens32 ifcfg-ens33
[root@control network-scripts]# vi ifcfg-ens33

此处网关可以不配。

如果你是在远程连接上修改的ip，在重启network服务后，远程连接需要重新连接

当两台主机的网络都通了，接下来如何做？

关机，拍快照

为什么要拍快照？

当你后续操作有问题，但你自己不会修改怎么办？重新配一台虚拟机，显然不可能，所以直接快照回返，从网络互通开始，更加省时省力。

配置yum仓库

由于centos7的源已经过期了，那么怎么办？

使用阿里云的源

初始化数据库

[root@control ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
 SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 这里直接回车即可
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y 是否设置数据库的 root 密码 Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y 是否删除匿名用户 Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n 是否禁用 root 的远程登录
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y 是否现在刷新表权限 Y
 ... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

安装消息队列【仅控制节点】

[root@control ~]# yum install rabbitmq-server -y

text

启动服务，并开机自启

[root@control ~]# systemctl enable --now rabbitmq-server.service
Created symlink from /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to /usr/lib/systemd/system/rabbitmq-server.service.

Bash

添加一个用户“example01” 密码是redhat

[root@control ~]# rabbitmqctl add_user example01 redhat
Creating user "example01"

text

为rabbitmq用户授予对消息队列中所有资源的权限

[root@control ~]# rabbitmqctl set_permissions example01 ".*" ".*" ".*"
Setting permissions for user "example01" in vhost "/"

".*"：第一个".*"表示该用户对所有虚拟主机（vhost）拥有权限。如果只想授予特定虚拟主机的权限，可以替换为具体的虚拟主机名称，如 myvhost。

".*"：第二个".*"表示该用户对所有配置（如交换机和队列绑定）拥有权限。配置权限允许用户创建、删除和查询交换机和队列。

".*"：第三个".*"表示该用户对所有消息操作（如发送和接收消息）拥有权限。消息权限允许用户在队列上执行读写操作

Bash

RabbitMQ 是一个开源的消息代理软件，用于实现消息队列，使用 AMQP（高级消息队列协议）来进行消息的交换和传输，RabbitMQ 默认情况下使用两个端口号：25672和15672。默认仅开启 25672 端口，该端口通常用于内部节点通信，而不是作为客户端连接的端口。而 15672 端口是 RabbitMQ 的 Web 管理界面的默认端口。通过浏览器访问http://<RabbitMQ服务器IP地址>:15672，可以打开RabbitMQ 的管理控制台。管理员可以使用这个界面来监视、管理和配置 RabbitMQ 实例，包括管理队列、交换机、绑定、用户、权限等。

开启15672端口

Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service.
[root@control ~]# ss -tunlp | grep 11211
