想把 api.example.com 解析到 123.123.123.123:8080/api 下

nginx 我已经配置了 api.example.com 123.123.123.123:8080

那个 /api 应该在哪里配置

upstream api__upstream {
    server 127.0.0.1:8080;
    keepalive 64;
}
server {
    listen 443 ssl;
    ssl_certificate "/etc/nginx/cert/api.pem";
    ssl_certificate_key "/etc/nginx/cert/api.key";
    ssl_protocols SSLv2 SSLv3 TLSv1;
    ssl_session_timeout 5m;
    ssl_prefer_server_ciphers on;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    server_name api.xxx.com;
    access_log /root/nginx.log;
    location / {
        proxy_pass http://api__upstream;
        proxy_set_header   X-Real-IP            $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-NginX-Proxy    true;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
}
server {
   listen 80;
   server_name api.xxxx.com;
   return 301 https://$server_name$request_uri;
}

去网上搜不知道应该按什么关键字搜这个问题 →_→

proxy_pass http://api__upstream/api;

靠，你在逗我
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
不应该是
ssl_protocols TLSv1.2 TLSv1.1 TLSv1;
然后删
ssl_prefer_server_ciphers on;
还有
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
吗
现在都 2017 年了，还有人用 SSLv2 SSLv3
那个做教程的人也不应该把什么加密协议 /套件写死

@zzq4343 我是在阿里云申请的免费 HTTPS 证书，二级域名的那个确实给的是 SSLv2 SSLv3 TLSv1 ，根域名是 TLSv1.2 TLSv1.1 TLSv1 。不安全？

@gqkkk 试了一下，可以的， api 后边再加个“/”。棒棒哒！

@Sirormy 不建议使用 SSLv2 SSLv3 印象中好像是著名的心血漏洞什么的~

像我这种小白，用这个生成 nginx 配置文件 https://mozilla.github.io/server-side-tls/ssl-config-generator/

安利给楼主试试

不懂乱说光速逃跑 : )

rewrite ^(.*)$ http://api.example.com/api$1 permanent;

@Sirormy 当然不安全
用 SSLv2 就是找死，参考 DROWN 攻击 ( https://drownattack.com/ )，不仅是开启 SSLv2 的机器本身会泄密，别的机器，只要使用一样的 RSA 密钥，就算你用 TLSv1.2 一样泄密。
SSLv3 是 POODLE 攻击 ( https://censys.io/blog/poodle )，没有 SSLv2 严重，但是与任何 CBC 模式的块加密算法 (比如 AES-CBC, 3DES-EDE-CBC) 使用就会泄密，除非使用 RC4 ，问题是 RC4 也不安全( https://www.rc4nomore.com/ )，一个 cookie 在一个普通电脑上 75 小时破解
@neroxps 不是什么 Heartbleed ，那个漏洞由于大家都很重视，基本上不存在了
