redis-server8.4编译安装

2025-11-22 Linux YY.K Permalink

debian源的版本比较老，而且redis-redisearch更老。

安装新版本ReJSON和RediSearch啥都有, 就是启动服务的时候官方service加载search就会卡住。

编译太麻烦了从docker镜像直接拉现成的

MariaDB找出占用CPU的sql查询

2025-11-19 Linux YY.K Permalink

#!/bin/bash
TOP_N=${2:-10}
PID=$(pgrep -o -x mysqld) 
[ -z "$PID" ] && PID=$(pgrep -o -x mariadbd)
TID=`top -H -p $PID -b -n 1 | tail -n +8 | awk -v pid="$PID" '$1 != pid {printf "%s\t%s\n",$1,$9}' | sort -k2 -nr | head -n $TOP_N|awk '{ print $1 }'|paste -sd ',' -`
mariadb -h'127.0.0.1' -P'3306' -u'root' -p'密码'  -e "SELECT * FROM information_schema.processlist WHERE tid IN ($TID) ORDER BY time DESC;"

根据MariaDB的PID查询出PID，再根据TID去information_schema.processlist里面找出对应的sql查询。

KasmVNC的kasmweb项目

2025-11-19 Linux YY.K Permalink

最近需遍历查看几十万个图片文件，虽然能通过http进行遍历，但涉及到操作文件要另外写代码。

kasmweb的ubuntu-jammy-desktop镜像帮我省掉了很多事，直接进去操作，整体很流畅。

podman run -d \
  --restart=unless-stopped \
  --name ubuntu-desktop \
  --hostname ubuntu-desktop \
  --shm-size=5120m \
  -p 6901:6901 \
  -e VNC_PW=password \
  -e LANG=zh_CN.UTF-8 \
  -e LANGUAGE=zh_CN:zh \
  -e LC_ALL=zh_CN.UTF-8 \
  -v /www:/www \
  --user 0:0 \
  docker.io/kasmweb/ubuntu-jammy-desktop:1.18.0

使用 --user 0:0 提权为root

-p是端口映射

容器启动后访问 https://IP:6901 有条件的做个反向代理

默认访问用户名是kasm-user密码则是 -e VNC_PW参数

进入root方法

podman exec -it -u root ubuntu-desktop bash
sudo -i

出现401验证错误解决办法

podman exec -it -u root ubuntu-desktop bash
#进入容器后重置密码
VNC_PW=密码
echo -e "${VNC_PW}\n${VNC_PW}\n" | kasmvncpasswd -u kasm_user -wo
echo -e "${VNC_PW}\n${VNC_PW}\n" | kasmvncpasswd -u kasm_viewer -r

备份vscode TG数据办法

mkdir  /data/opt -p
podman cp ubuntu-desktop :/opt /data/opt
 
#重新创建容器加上参数
-v /data/opt:/opt \

重启容器

podman restart ubuntu-desktop

停止和删除容器

podman stop ubuntu-desktop
podman rm ubuntu-desktop

thinkphp file cache文具数量疑似无限增长问题

2025-11-11 Linux YY.K Permalink

发现缓存数量无限增多，好像是没有自动清除过期缓存，如果是SSD硬盘要注意大量文件读写问题导致过度消耗硬盘寿命。

最好还是redis缓存为好。

AlmaLinux出现libutilkeybd.so报错

2025-11-05 Linux YY.K Permalink

最近接了几个运维的活，更新内核的时候 dracut生成 initrd失败，大量出现关键词libutilkeybd.so

追溯文件日期是9月21日，起初还以为是AlmaLinux的问题。

除了dracut，用ldd和losf也能看到被注入。

清空ld.so.preload和删除文件后系统正常了。
