Nginx是一款高性能的Web服务器和反向代理服务器,广泛应用于互联网领域。作为一名前端同学,了解并掌握Nginx的配置是非常有必要的。
安装Nginx
sudo apt-get update
sudo apt-get install nginx
查看Nginx版本
nginx -v
启动、停止、重启Nginx服务
sudo service nginx start # 启动Nginx服务
sudo service nginx stop # 停止Nginx服务
sudo service nginx restart # 重启Nginx服务
Nginx配置文件结构
Nginx的主配置文件位于/etc/nginx/nginx.conf,其他配置文件位于/etc/nginx/sites-available目录下。每个站点的配置文件以站点名命名,如default、example.com等。
server {
listen 80; # 监听端口号
server_name example.com; # 域名或IP地址
root /var/www/html; # 网站根目录
index index.html; # 默认首页文件名
}
创建站点配置文件
在/etc/nginx/sites-available目录下创建一个名为example.com的文件,并将上述配置内容复制到该文件中。然后创建一个符号链接到/etc/nginx/sites-enabled目录下:
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/example.com
重启Nginx服务使配置生效
sudo service nginx restart
至此,你已经成功配置了一个基本的Nginx站点。当然,Nginx还有很多高级功能,如负载均衡、缓存、SSL等,可以根据需要进行配置。
Nginx配置示例
基础配置:
user root;
worker_processes 1;
events {
worker_connections 10240;
}
http {
log_format '$remote_addr - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent ' '"$http_referer" "$http_user_agent"';
include mime.types;
default_type application/octet-stream;
sendfile on;
#autoindex on;
#autoindex_exact_size off;
autoindex_localtime on;
keepalive_timeout 65;
gzip on;
gzip_disable "msie6";
gzip_min_length 100;
gzip_buffers 4 16k;
gzip_comp_level 1;
gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
gzip_types "*";
gzip_vary off;
server_tokens off;
client_max_body_size 200m;
server {
listen 80 default_server;
server_name _;
return 403 /www/403/index.html;
}
include ../serve/*.conf;
}
隐藏 Nginx 版本信息:
http {
server_tokens off;
}
禁止ip直接访问80端口
server {
listen 80 default;
server_name _;
return 500;
}
启动 web 服务 (vue 项目为例)
server {
# 项目启动端口
listen 80;
# 域名(localhost)
server_name _;
# 禁止 iframe 嵌套
add_header X-Frame-Options SAMEORIGIN;
# 访问地址 根路径配置
location / {
# 项目目录
root html;
# 默认读取文件
index index.html;
# 配置 history 模式的刷新空白
try_files $uri $uri/ /index.html;
}
# 后缀匹配,解决静态资源找不到问题
location ~* \.(gif|jpg|jpeg|png|css|js|ico)$ {
root html/static/;
}
# 图片防盗链
location ~/static/.*\.(jpg|jpeg|png|gif|webp)$ {
root html;
valid_referers *.deeruby.com;
if ($invalid_referer) {
return 403;
}
}
# 访问限制
location /static {
root html;
# allow 允许
allow 39.xxx.xxx.xxx;
# deny 拒绝
deny all;
}
}
PC端和移动端使用不同的项目文件映射
server {
......
location / {
root /home/static/pc;
if ($http_user_agent ~* '(mobile|android|iphone|ipad|phone)') {
root /home/static/mobile;
}
index index.html;
}
}
一个web服务,配置多个项目 (location 匹配路由区别)
server {
listen 80;
server_name _;
# 主应用
location / {
root html/main;
index index.html;
try_files $uri $uri/ /index.html;
}
# 子应用一
location ^~ /store/ {
proxy_pass http://localhost:8001;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# 子应用二
location ^~ /school/ {
proxy_pass http://localhost:8002;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# 静态资源读取不到问题处理
rewrite ^/api/profile/(.*)$ /(替换成正确路径的文件的上一层目录)/$1 last;
}
# 子应用一服务
server {
listen 8001;
server_name _;
location / {
root html/store;
index index.html;
try_files $uri $uri/ /index.html;
}
location ^~ /store/ {
alias html/store/;
index index.html index.htm;
try_files $uri /store/index.html;
}
# 接口代理
location /api {
proxy_pass http://localhost:8089;
}
}
# 子应用二服务
server {
listen 8002;
server_name _;
location / {
root html/school;
index index.html;
try_files $uri $uri/ /index.html;
}
location ^~ /school/ {
alias html/school/;
index index.html index.htm;
try_files $uri /school/index.html;
}
# 接口代理
location /api {
proxy_pass http://localhost:10010;
}
}
配置负载均衡
upstream my_upstream {
server http://localhost:9001;
server http://localhost:9002;
server http://localhost:9003;
}
server {
listen 9000;
server_name test.com;
location / {
proxy_pass my_upstream;
proxy_set_header Host $proxy_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
SSL 配置 HTTPS
server {
listen 80;
server_name www.xxx.com;
# 将 http 重定向转移到 https
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
server_name www.xxx.com;
ssl_certificate /etc/nginx/ssl/www.xxx.com.pem;
ssl_certificate_key /etc/nginx/ssl/www.xxx.com.key;
ssl_session_timeout 10m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
root /project/xxx;
index index.html index.htm index.md;
try_files $uri $uri/ /index.html;
}
}
