遇到的一些问题

大文件无法上传

server{
    client_max_body_size   30m;  # 默认是1m
    ...
}

常用配置

server {
    listen 80;
    server_name hostname.com;
    location / {
        if ($request_method = GET) {
            rewrite  ^ https://$host$request_uri? permanent;  # http强制跳转
        }
        return 405;
    }
    access_log /var/log/nginx/hostname/hostname.log main;
}
server {
    listen 443;
    server_name hostname.com;
    client_max_body_size   10m;
    ssl on;
    ssl_certificate      /etc/nginx/ssl/hostname.com.crt;  # ssl证书
    ssl_certificate_key  /etc/nginx/ssl/hostname.com.key;
    proxy_set_header   Host                 $http_host;
    proxy_set_header   X-Forwarded-Proto    $scheme;
    proxy_set_header   X-Forwarded-For      $remote_addr;
    proxy_redirect     off;
    # keepalive + raven.js is a disaster
    keepalive_timeout 0;
    location / {
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        proxy_pass http://localhost:8000;
        add_header Strict-Transport-Security "max-age=31536000";
    }
    access_log /var/log/nginx/hostname/hostname_ssl.log main;
    error_log /var/log/nginx/hostname/hostname_ssl_error.log;
}

正则配置

等号（=）:表示完全匹配规则才执行操作

1	location = / {}

波浪号（~）:表示执行正则匹配，但区分大小写

1	location ~ /page/\d{1,3} {}

波浪号与星号（~*）:表示执行正则匹配，但不区分大小写

1	location ~* /\.(jpg\|jpeg\|gif) {}

脱字符与波浪号（^~）:表示普通字符匹配，前缀匹配有效，配置生效

1	location ^~ /images/ {} # http://{hostname}/images/test

@ :定义一个location，用于处理内部重定向

location @error {
    proxy_pass http://error;
}
error_page 404 @error;
