分享一个Nginx反向代理配置

废话不多，上配置：

server {
listen 80;
listen 443 ssl http2;
server_name cikeblog.com;
ssl_certificate /root/.acme.sh/cikeblog.com/fullchain.cer;
ssl_certificate_key /root/.acme.sh/cikeblog.com/cikeblog.com.key;
ssl_prefer_server_ciphers on;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_session_cache shared:SSL:5m;
ssl_session_timeout 5m;
keepalive_timeout 75s;
keepalive_requests 100;

if ($scheme = http) {
return 301 https://$host$request_uri;
}

gzip on;
gzip_comp_level 6;
gzip_min_length 1k;
gzip_types text/plain text/css text/xml text/javascript text/x-component application/json application/javascript application/x-javascript application/xml application/xhtml+xml application/rss+xml application/atom+xml application/x-font-ttf application/vnd.ms-fontobject image/svg+xml image/x-icon font/opentype;

location / {
proxy_pass http://127.0.0.1:81;
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 Upgrade $http_upgrade;
client_max_body_size 1m;
}
}

需要注意的地方如下：
证书信息，如果不需要ssl，删除以下信息：

ssl_certificate /root/.acme.sh/cikeblog.com/fullchain.cer;
ssl_certificate_key /root/.acme.sh/cikeblog.com/cikeblog.com.key;

以及：

listen 443 ssl http2;

配置反代地址：

proxy_pass http://127.0.0.1:81;
