CentOS 7部署DHCP服务.docx
要在CentOS 7上使用Docker部署DHCP服务,需要执行以下步骤:
1. 安装Docker和docker-compose:
```bash
sudo yum install -y docker docker-compose
sudo systemctl start docker
sudo systemctl enable docker
```
2. 创建一个Dockerfile文件,内容如下:
```Dockerfile
FROM centos:7
RUN yum -y update && \
yum -y install dhcp && \
yum -y clean all
COPY dhcpd.conf /etc/dhcp/dhcpd.conf
ENTRYPOINT ["dhcpd", "-f", "-d", "-cf", "/etc/dhcp/dhcpd.conf", "-lf", "/var/lib/dhcpd/dhcpd.leases", "--no-pid"]
```
3. 创建一个dhcpd.conf文件,内容如下:
```conf
option domain-name "example.com";
option domain-name-servers 8.8.8.8, 8.8.4.4;
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
option routers 192.168.1.1;
}
```
4. 创建一个docker-compose.yml文件,内容如下:
```yaml
version: '3'
services:
dhcpd:
build: .
ports:
- "67:67/udp"
volumes:
- ./dhcpd.conf:/etc/dhcp/dhcpd.conf
- /var/lib/dhcpd:/var/lib/dhcpd
network_mode: "host"
restart: always
```
5. 在包含Dockerfile,dhcpd.conf和docker-compose.yml文件的目录中运行以下命令来启动DHCP服务:
```bash
sudo docker-compose up -d
```
6. 确认DHCP服务是否已成功启动:
```bash
sudo docker-compose ps
```
现在,您可以使用该DHCP服务器提供IP地址和其他DHCP选项了。
