VPS如何设置才能保持24小时不间断运行？

VPS 24小时稳定运行配置指南

一、基础设置步骤

1. 系统配置优化

• 禁用自动休眠功能：

     sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
     

• 设置定时任务保持活跃：

     echo "  *   root echo 1 > /proc/sys/vm/dropcaches" | sudo tee -a /etc/crontab
     

     # /etc/netplan/01-netcfg.yaml
     network:
       version: 2
       renderer: networkd
       ethernets:
         enp0s3:
           addresses: [192.168.1.100/24]
           gateway4: 192.168.1.1
           nameservers:
             addresses: [8.8.8.8, 1.1.1.1]
     

     http {
         upstream backend {
             server backend1.example.com;
             server backend2.example.com;
         }
         server {
             listen 80;
             location / {
                 proxypass http://backend;
             }
         }
     }
     

1. 自动化运维方案

• 配置Ansible批量管理：

     # playbook.yml

hosts: vps_servers

       tasks:

name: Ensure services running

           systemd:
             name: "{{ item }}"
             state: started
             enabled: yes
           loop:

sshd
nginx
mysql
