准备信息

官方资料：https://www.isc.org/kea/
安装版本：
- kea - DHCP主程序：v1.9.10
- stork - 仪表盘：v0.19.0
安装环境：Debian 11 x64
项目仓库：
- kea:
  - GitHub: https://github.com/isc-projects/kea
  - GitLab: https://gitlab.isc.org/isc-projects/kea
- stork:
  - GitHub: https://github.com/isc-projects/stork
安装目标：
- 1、使用kea实现DHCP
- 2、使用stork用作Web仪表盘（只能看不能操作）
安装依赖：

简易安装项
- gcc
- g++
- curl
- make
- autoconf
- libtool
- libmysql+±dev
- libboost-system-dev
需要配置安装项
- mysql/mariadb
- PostgreSQL
源码编译安装
- log4cplus

安装kea步骤

注意：本次安装过程所用操作使用root账户进行

1、初始化环境

安装依赖项

apt install gcc g++ curl make libtool autoconf libmysql++-dev libboost-system-dev

安装log4cplus
仓库缺少ThreadPool，需要手动下载：

下载链接：Github
附件：文末

mkdir ~/src/log4cplus
cd ~/src/log4cplus
wget https://github.com/log4cplus/log4cplus/archive/refs/tags/REL_2_0_7.tar.gz
tar zxvf REL_2_0_7.tar.gz
cd log4cplus-REL_2_0_7/
# 此处需要将下载的ThreadPool.h头文件放到 threadpool/目录
./configure
make
make install

2、安装并配置数据库（此处安装mariadb-server）

# apt安装
apt install mariadb-server

# 初始化mariadb
mysql_secure_installation
# 输入原来的root密码，没有密码直接回车就可以了
# Enter current password for root (enter for none): 
# 更改root密码？
# Change the root password?
# 删除匿名用户？
# Remove anonymous users?
# 禁用root远程登录？
# Disallow root login remotely?
# 是否删除test测试数据库？
# Remove test database and access to it?
# 重新加载权限数据表
# Reload privilege tables now?

# 若需要更改远程访问
# 更改数据库配置，绑定IP设置为0.0.0.0
vim /etc/mysql/mariadb.conf.d/50-server.cnf
# 更改 bind-address 字段

# 创建数据库与用户
mysql -u root
MariaDB [mysql]> use mysql;
MariaDB [mysql]> select host,user from user;
+-----------+-------------+
| Host      | User        |
+-----------+-------------+
| localhost | mariadb.sys |
| localhost | mysql       |
| localhost | root        |
+-----------+-------------+
3 rows in set (0.002 sec)
# 创建数据库 CREATE DATABASE <database>;
MariaDB [mysql]> CREATE DATABASE w21DHCP;

# 创建数据库用户 CREATE USER '<user>'@'localhost' IDENTIFIED BY '<password>';
MariaDB [mysql]> CREATE USER 'w21dhcp'@'localhost' IDENTIFIED BY 'w21@dhcp';
MariaDB [mysql]> flush privileges;

# 授权数据库给对应用户所有权 GRANT ALL ON <database>.* to '<user>'@'localhost' IDENTIFIED BY '<password>';
MariaDB [mysql]> GRANT ALL ON w21DHCP.* to 'w21dhcp'@'localhost' IDENTIFIED BY 'w21@dhcp';
MariaDB [mysql]> flush privileges;

3、编译安装kea

mkdir ~/src/kea
cd ~/src/kea
wget https://github.com/isc-projects/kea/archive/refs/tags/Kea-1.9.10.tar.gz
tar zxvf Kea-1.9.10.tar.gz
cd kea-Kea-1.9.10/
autoreconf --install
./configure --with-mysql
make
make install

4、初始化kea数据库
此处提供两种初始化方法

方法1：通过kea-admin自动初始化

# kea-admin db-init mysql -u <user> -p <password> -n <database>
kea-admin db-init mysql -u w21dhcp -p w21@dhcp -n w21DHCP

方法2：手动导入Mysql数据表

# CONNECT <database>;
# SOURCE path-to-kea/share/kea/scripts/mysql/dhcpdb_create.mysql
mysql> CONNECT w21DHCP;
mysql> SOURCE path-to-kea/share/kea/scripts/mysql/dhcpdb_create.mysql

安装stork仪表盘

参考链接：Installing the Stork Server

1、安装stork

Ubuntu/Debian

curl -1sLf 'https://dl.cloudsmith.io/public/isc/stork/cfg/setup/bash.deb.sh' | sudo bash
sudo apt install isc-stork-server

CentOS/RHEL/Fedora

curl -1sLf 'https://dl.cloudsmith.io/public/isc/stork/cfg/setup/bash.rpm.sh' | sudo bash
sudo dnf install isc-stork-server

2、安装PostgreSQL并配置数据库

apt-get install postgresql
su postgresql
createdb storkdb
psql
postgres=# CREATE USER stork WITH PASSWORD 'w21@stork';
postgres=# GRANT ALL PRIVILEGES ON DATABASE storkdb TO stork;

2、配置数据库
编辑配置文件：/etc/stork/server.env

STORK_DATABASE_HOST - PostgreSQL 数据库的地址；默认是本地主机
STORK_DATABASE_PORT - PostgreSQL 数据库的端口；默认值为5432
STORK_DATABASE_NAME - 数据库名称；默认是stork
STORK_DATABASE_USER_NAME - 连接数据库的用户名；默认是stork
STORK_DATABASE_PASSWORD - 连接到数据库的用户名的密码

3、启动stork

# 启动
systemctl start isc-stork-server

# 添加开机自启动
systemctl enable isc-stork-server
