# Nginx静态文件服务器怎么配置
Nginx作为高性能的Web服务器和反向代理服务器,常被用于搭建静态资源服务器。本文将详细介绍如何从零开始配置Nginx静态文件服务器,包括基础配置、优化技巧和常见问题解决方案。
## 一、环境准备与安装
### 1. 安装Nginx
在主流Linux发行版上安装Nginx:
```bash
# Ubuntu/Debian
sudo apt update
sudo apt install nginx
# CentOS/RHEL
sudo yum install epel-release
sudo yum install nginx
# 验证安装
nginx -v
建议的静态资源目录结构:
/var/www/
└── static.example.com
├── images
├── css
├── js
└── downloads
创建目录并设置权限:
sudo mkdir -p /var/www/static.example.com
sudo chown -R $USER:$USER /var/www/static.example.com
chmod -R 755 /var/www
编辑Nginx主配置文件(通常位于/etc/nginx/nginx.conf
),确保包含以下基础参数:
user www-data;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
# 包含独立站点配置
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
创建站点配置文件/etc/nginx/conf.d/static.conf
:
server {
listen 80;
server_name static.example.com;
root /var/www/static.example.com;
index index.html;
location / {
try_files $uri $uri/ =404;
autoindex off; # 默认关闭目录列表
}
access_log /var/log/nginx/static.access.log;
error_log /var/log/nginx/static.error.log;
}
# 测试配置语法
sudo nginx -t
# 重载配置
sudo systemctl reload nginx
在http
块中添加:
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
gzip_min_length 1024;
gzip_comp_level 6;
添加缓存头设置:
location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
expires 30d;
add_header Cache-Control "public, no-transform";
}
location ~* \.(jpg|jpeg|png|gif)$ {
valid_referers none blocked static.example.com *.example.com;
if ($invalid_referer) {
return 403;
}
}
location /downloads/ {
sendfile on;
tcp_nopush on;
aio on;
directio 8m;
output_buffers 4 128k;
}
server_tokens off;
if ($request_method !~ ^(GET|HEAD)$ ) {
return 405;
}
location ~ /\. {
deny all;
access_log off;
log_not_found off;
}
location /share/ {
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
}
error_page 404 /404.html;
location = /404.html {
root /var/www/static.example.com/errors;
internal;
}
log_format static_log '$remote_addr - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent '
'"$http_referer" "$http_user_agent"';
access_log /var/log/nginx/static.access.log static_log;
使用Let’s Encrypt免费证书:
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d static.example.com
server {
listen 443 ssl http2;
server_name static.example.com;
ssl_certificate /etc/letsencrypt/live/static.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/static.example.com/privkey.pem;
# 其他配置与HTTP版本相同
}
worker_processes auto; # 自动匹配CPU核心数
worker_rlimit_nofile 65535; # 每个worker能打开的文件描述符数量
events {
worker_connections 4096;
multi_accept on;
use epoll;
}
编辑/etc/sysctl.conf
:
net.core.somaxconn = 65535
net.ipv4.tcp_max_syn_backlog = 65535
fs.file-max = 2097152
执行sysctl -p
生效
可能原因: - 目录权限不足 - SELinux限制 - root路径配置错误
解决方案:
chmod -R 755 /var/www
chown -R nginx:nginx /var/www
setsebool -P httpd_read_user_content 1 # CentOS SELinux
检查: - MIME类型是否正确 - 文件路径大小写是否匹配 - 浏览器缓存是否干扰
使用工具分析:
top -H -p $(pgrep nginx) # 查看进程负载
iftop -i eth0 # 网络流量监控
goaccess /var/log/nginx/access.log --log-format=COMBINED # 访问日志分析
# 启动/停止/重启
sudo systemctl start nginx
sudo systemctl stop nginx
sudo systemctl restart nginx
# 查看状态
systemctl status nginx
nginx -T # 查看完整配置
默认已配置logrotate,配置文件位于/etc/logrotate.d/nginx
通过本文的详细指导,您应该已经能够配置一个高性能的Nginx静态文件服务器。实际部署时,请根据业务需求调整各项参数,并定期进行安全检查和性能优化。Nginx的强大功能远不止于此,建议继续探索其作为反向代理、负载均衡器等更多应用场景。 “`
