nacos安装

Wed, 08 Apr 2026 10:42:55 +0800

官方文档： https://nacos.io/docs/latest/quickstart/quick-start/?spm=5238cd80.72a042d5.0.0.5bc0cd36gYSNAV

bin目录下启动命令：

startup.cmd -m standalone

启动报错指南： https://blog.csdn.net/qq_45063782/article/details/119751892 https://blog.csdn.net/weixin_45396074/article/details/135177158

需要在本地mysql手动创建nacos数据库修改配置： secret.key 不得少于32位，不然会报错，直接把官方的注释解开即可

ubuntu数据库备份脚本

Wed, 08 Apr 2026 10:42:52 +0800

创建备份脚本：

创建一个名为mysql_backup.sh的脚本文件，并添加以下内容：

 #!/bin/bash

 # 数据库配置信息
 DB_USER="root"
 DB_PASS="your_password"
 DB_NAME="testdb"
 BACKUP_DIR="/home/backup"

 # 备份文件名
 BACKUP_FILE="$BACKUP_DIR/${DB_NAME}_$(date +%Y%m%d%H%M%S).sql.gz"

 # 执行备份命令
 mysqldump -u $DB_USER -p$DB_PASS $DB_NAME | gzip > $BACKUP_FILE

 # 删除30天前的备份文件
 find $BACKUP_DIR -type f -name "*.gz" -mtime +30 -exec rm {} \;

注意：将your_password替换为实际的数据库密码。
