# Let's Encrypt证书申请
sudo certbot certonly --standalone -d example.com -d www.example.com
sudo ln -s /etc/letsencrypt/live/example.com/fullchain.pem /etc/ssl/certs/ssl-cert-snakeoil.pem
sudo ln -s /etc/letsencrypt/live/example.com/privkey.pem /etc/ssl/private/ssl-cert-snakeoil.key

2 Web应用防火墙配置

# WAF规则示例(ModSecurity)
SecRuleEngine On
SecAction "id:200101, phase:2, variable:HTTP_X_FORWARDED_PROTO, action:Block,Found true"

3 漏洞扫描与修复

# OpenVAS扫描命令
sudo openVAS --batch --xml --output report.xml
# 自动化修复脚本(基于Ansible)
---

  become: yes

性能优化方案(约800字)

1 响应时间监控

# Prometheus监控配置
 metric_relabelings:
- source labels: [job_name]
  target labels: [service_name]
 alerting:
  alert: High_Latency
  expr: rate(nginx响应时间5m) > 2000
  for: 5m
  labels:
    severity: critical

2 缓存策略优化

# HTTP缓存配置
location /static/ {
    cache_max_age 302d;
    proxy_cache_path /var/cache/nginx level=1:2 keys_zone=static:10m;
    proxy_pass http://static-server;
}
# Redis缓存连接池
Redis连接池配置:
max连接数 20
min空闲连接数 5
连接超时 5秒

3CDN加速配置

# Cloudflare配置步骤
1. 创建 Workers脚本:
   ```javascript
   addEventListener('fetch', event => {
     event.respondWith(handleRequest(event.request));
   });
   async function handleRequest(request) {
     const url = new URL(request.url);
     url.hostname = 'cdn.example.com';
     const newRequest = new Request(url, request);
     return fetch(newRequest);
   }
  1. 启用HTTP/3协议
  2. 配置DNS记录为CNAME

高可用架构设计(约600字)

1 负载均衡集群

# HAProxy配置示例
global
    log /dev/log local0
    maxconn 4096
mode http
    balance roundrobin
listen http-in 0.0.0.0:80
    server app1 192.168.1.100:80 check
    server app2 192.168.1.101:80 check
listen https-in 0.0.0.0:443
    ssl certificate /etc/letsencrypt/live/example.com/fullchain.pem
    ssl key /etc/letsencrypt/live/example.com/privkey.pem
    server app1 192.168.1.100:443 check
    server app2 192.168.1.101:443 check

2 数据库主从同步

# MySQL主从同步配置
[mysqld]
log_bin = /var/log/mysql binlog.000001
binlog_format = row
server_id = 1
[client]
port = 3306
# 从节点配置
[mysqld]
log_bin = /var/log/mysql binlog.000001
binlog_format = row
replication_type = synchronous
replication源 = 192.168.1.100

运维管理工具(约500字)

1 智能监控平台

# Zabbix监控配置
- Template: Web Server (Nginx)
  Items:
    - Nginx进程状态 (Process count)
    - 平均响应时间 (Average response time)
    - 错误日志计数 (Error log count)
  Triggers:
    - If Average response time > 2000ms for 5 minutes, send alert

2 自动化运维工具

# Ansible Playbook示例
---
- name: Install PHP extensions
  package:
    name: 
      - php-mbstring
      - php-gd
      - php-xml
    state: present
- name: Configure Nginx
  template:
    src: nginx.conf.j2
    dest: /etc/nginx/conf.d/app.conf
  notify: restart nginx
 handlers:
  - name: restart nginx
    service:
      name: nginx
      state: restarted

常见问题解决方案(约400字)

1 常见报错处理

# 502 Bad Gateway
检查:
1. 负载均衡健康检查配置
2. 后端服务器端口监听状态
3. 证书过期时间
修复:
sudo systemctl restart ha-proxy
# 403 Forbidden
配置:
location / {
    allow all;
    deny all;
    access_log off;
}

2 性能瓶颈排查

# 性能分析命令
sudo mpstat 1 5
sudo vmstat 1 5
sudo iostat -x 1 5
sudo ngrep -d eth0 'tcp and (port 80 or port 443)'
# 典型优化方向:
1. 连接数限制(max_connections=1000)
2. 缓存命中率提升(目标>90%)
3. 启用HTTP/2(Nginx+SSL配置)
