[feat] readme
基于 Apollo 的 SmartDNS 配置管理工具
go version >= 1.22
./build.sh
会生成 aarch64 x86 等平台的二进制程序
运行目录 /opt/cmclient
将对应平台的程序拷贝到运行目录，命名为 cmclient
拷贝 cmclient.yaml.demo 到运行目录，命名为 cmclient.yaml
拷贝 cmclient.service 到 /etc/systemd/system/
sudo systemctl daemon-reload
下面是 cmclient.yaml 的配置说明
configServer: http://192.168.74.40:8080 #Apollo Config Server 地址
appId: smartdns # Apollo Appid
cluster: beijing # Apollo 集群名称
accessKey: xxxx # Apollo 鉴权 AppKey
targetConfig: /etc/smartdns/conf.d/ # 将生成的配置存在哪里？
reloadCmd: /usr/bin/systemctl restart smartdns # 重启服务的命令
namespaces:
- service
- nameservers.txt
- rules.txt
- domains
根据 SmartDNS 文档进行安装
创建 /etc/smartdns/conf.d/ 目录
创建 smartdns.conf 内容如下
conf-file conf.d/*.conf
