 快速物理备份并压缩

#!/bin/bash
mysql_port="3308"
host_name=$(hostname)
# 设置保留的备份数量
retain_days=5
# 定义备份目录
backup_dir="/data/backup/mysql_backup/${host_name}_${mysql_port}"
mkdir -p $backup_dir

# 定义备份文件名
backup_file="mysql_backup_$(date +%Y%m%d%H%M%S).tar.gz"

# 使用innobackupex进行全量备份，并将备份文件压缩为.tar.gz格式
/data/glc/soft/percona-xtrabackup-2.4.27-Linux-x86_64.glibc2.12/bin/innobackupex --defaults-file=/data/glc/mysql_3306/conf/my.cnf   --login-path=backup_3306 --no-timestamp --slave-info --stream=xbstream  ${backup_dir} |gzip  > ${backup_dir}/${backup_file}

# 删除旧的备份文件，只保留最近5天的备份文件
find $backup_dir -maxdepth 1 -name "mysql_backup_*" -type f -mtime +$retain_days -delete

 快速生成32位密码：

[root@xxx scripts]# cat password_new.sh 
#!/bin/bash 
username=$1
user_password=$(date +%s |sha256sum|base64|head -c 32)
new_time=$(date '+%Y%m%d%H%M%S')
mysql_user='root'
mysql_passwd='root'
mysql_port=3306
mysql_host==''

echo "username: $username"
echo "password: $user_password"
echo "time: $new_time" >> log.password_new
echo "username: $username" >>log.password_new
echo "password: $user_password" >>log.password_new
