# 114.66.54.70 Nginx 配置 (服务器2)
#
# 部署步骤:
# 1. 上传配置: scp nginx-114.66.54.70.conf root@114.66.54.70:/tmp/
# 2. 复制配置: sudo cp /tmp/nginx-114.66.54.70.conf /etc/nginx/sites-available/api.conf
# 3. 启用配置: sudo ln -s /etc/nginx/sites-available/api.conf /etc/nginx/sites-enabled/
# 4. 从服务器1复制SSL证书:
#    scp -r root@110.42.32.207:/etc/nginx/ssl /etc/nginx/
# 5. 测试重载: sudo nginx -t && sudo systemctl reload nginx
