CentOS 上 DOPRA 自动化管理落地方案
一 适用前提与名词澄清
二 配置管理与批量编排
sudo yum install -y epel-release && sudo yum install -y ansible- hosts: webservers
become: yes
vars:
dopra_version: "1.2.3"
dopra_conf: /etc/dopra/dopra.conf
tasks:
- name: 安装 DOPRA 软件包
yum:
name: "dopra-{{ dopra_version }}"
state: present
- name: 渲染主配置(Jinja2 模板)
template:
src: templates/dopra.conf.j2
dest: "{{ dopra_conf }}"
owner: root
group: root
mode: 0644
notify: restart dopra
- name: 确保服务开机自启并运行
service:
name: dopra
state: started
enabled: yes
handlers:
- name: restart dopra
service:
name: dopra
state: restarted
ansible-playbook -i inventory dopra.yml三 监控告警与日志采集
四 高可用与自动故障切换
sudo yum install -y pacemaker corosync pcspcs cluster init <node1_ip> ...、pcs cluster join <node1_ip>pcs resource create dopra systemd:dopra \
op start timeout=60s op stop timeout=60s op monitor timeout=30s interval=30s
pcs resource create vip ocf:heartbeat:IPaddr2 \
ip=192.168.1.200 cidr_netmask=24 op monitor interval=10s
pcs constraint colocation add vip with dopra INFINITY
pcs constraint order vip then dopra
pcs status、pcs resource cleanup、pcs cluster verify五 快速落地路线图
