1.主服务器需要反代到mini，但mini为动态IP，之前已经写了动态更新dns，但是时间太大了，修改为60s再测试一下；

location /compare_similarity {
# 其他配置
resolver 114.114.114.114 8.8.8.8 valid=60s;
}

2.mini上的nginx总是出现端口复用绑定失败的提醒，排查了一下似乎是因为macos的启动项设置造成的，关闭了开机启动nginx的plist配置，直接通过手动启动，问题解决。
报错信息如下：

通过launchctl关掉nginx，改为下面的手动命令管理nginx，报错就消失了

sudo /opt/homebrew/Cellar/nginx/sbin/nginx

3.mini上发现error.log已经有2G多了，用AI弄了一个手动切割脚本，再打开快多了.
新建clear.bash，增加执行权限，编辑内容

touch clear.sh
chmod u+x,g+x clear.sh
vi clear.sh

脚本内容如下

!/bin/bash
LOG_PATH="/usr/local/nginx/logs" # 你的日志路径

#YESTERDAY=$(date -v-1d +%Y-%m-%d)    # macOS 写法
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)   # linux 写法
# 1. 移动并重命名文件
mv ${LOG_PATH}/access.log ${LOG_PATH}/access_${YESTERDAY}.log
mv ${LOG_PATH}/error.log ${LOG_PATH}/error_${YESTERDAY}.log
# 2. 向 Nginx 发送信号重新创建 access.log
# 这是 Nginx 的特性：收到 USR1 信号后会关闭当前日志并重新打开（不重启服务）
kill -USR1 $(ps aux | grep "nginx: master process" | grep -v grep | awk '{print $2}')

4.blog新建文章总是链接跳转失败，后端报错如下，Gemini判断是localhost写法会导致ipv6问题，都建议改为127.0.0.1，问题解决
