nginx配置「锦上添花」的小修小补 1. 统一 SSL 配置块（可维护性）把重复的 ssl_* 指令抽成一个独立文件，主配置里 include 即可，例如：# /etc/nginx/ssl/ssl_best.conf ssl_certificate /etc/nginx/ssl/_baidu.com.crt; ssl_certificate_key /etc/nginx/ssl/_baidu.com.key; ssl_trusted_certificate /etc/nginx/ssl/_baidu.com.crt; ssl_session_timeout 1d; ssl_session_cache shared:SSL:10m; ssl_session_tickets off; ssl_protocols TLSv1.2 TLSv1.3; ssl_prefer_server_ciphers on; ssl_ciphers ECDHE-ECDSA^...............:ECDHE-RSA-AE^.............-GCM-SHA384;然后在每个 443 段里写一句：include ssl_best.conf; 配上路径，容器运行注意！ 比如include /etc/nginx/ssl/ssl_best.conf;以后换证书/调加密套件只改一行。2. 补充安全响应头（看情况用吧）新建 /etc/nginx/conf.d/security_headers.conf：add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Content-Type-Options "nosniff" always; add_header Referrer-Policy "strict-origin-when-cross-origin" always; # 如需上传或外链，按需调整 CSP add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';" always; add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;在 所有 443 段 的 location / 里加：include security_headers.conf; 配上路径，容器运行注意！ 比如include /etc/nginx/conf.d/security_headers.conf;（Tomcat 已自带 X-Frame-Options，nginx 再统一一次无冲突。）3. 代理头统一模板把 proxy 头也抽成 /etc/nginx/conf.d/proxy_headers.conf：proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header REMOTE-HOST $remote_addr; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";以后 location / 里只要写：proxy_pass http://backend_5800; include proxy_headers.conf; 比如include /etc/nginx/conf.d/proxy_headers.conf;Tomcat 路径同理。4. 小优化：正则 location 加 breaklocation ~ ^/(test|oa|ob|oc) { proxy_pass http://tomcat; include proxy_headers.conf; }• 正则 ~ 会顺序匹配，保持放在「普通 location /」前面即可。• 若担心性能，可改为：location /oa { ... } location /ob { ... }5. 可选：Tomcat 真实 IP 日志Tomcat 要记录访客真实 IP，在 server.xml 里加：<Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" />nginx 已传头，直接可用。{lamp/}附配置：{collapse}{collapse-item label="一、nginx的default.conf的配置"}# ---------- upstream ---------- upstream tomcat { server tomcat:8080;
