**安装：**
**安装全部组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t all
```
**仅安装 server 相关组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t server
```
**仅安装 exporter 相关组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t exporter
```
**安装自定义组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t 组件名称（名单见上方说明）
```
示例：安装 server 和 node exporter、cadvisor、blackbox exporter、promtail
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t server,node,docker,blackbox,promtail
```
**仅安装 Docker 服务：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=install -t dockerce
```
**卸载：**
**卸载全部组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t all
```
**仅卸载 server 相关组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t server
```
**仅卸载 exporter 相关组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t exporter
```
**卸载自定义组件：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t 组件名称（名单见上方说明）
```
示例：卸载 server 和 node exporter、cadvisor、blackbox exporter、promtail
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t server,node,docker,blackbox,promtail
```
**卸载 Docker 服务：**
```shell
ansible-playbook /etc/ansible/roles/role.yml -e @/etc/ansible/roles/conf/extend.yml -e cmd=remove -t dockerce
```
**注意：**
1. 当前仅测试部署 Server 相关、Node Exporter、cAdvisor
2. Prometheus Alert、Prometheus Mongodb Exporter、Prometheus Rocketmq Exporter、Prometheus JMX Exporter、Prometheus Zookeeper Exporter 仅支持 x86_64 架构处理器，故当服务器 CPU 架构不为 x86_64 时，对应的服务不会安装，tag 也无效。
3. 当主机已经安装 Docker 服务时，需要先创建对应的 Docker 网络，然后再执行脚本
```bash
docker network create Docker网络名称 --subnet Docker网络网段
```
示例如下：
```bash
docker network create --driver bridge --opt encrypted:'true' --subnet 10.21.22.0/24 prometheus
```
