要是军哥在加一个自动备份网站数据和数据库的命令脚本就更完美了? 求指导
要是军哥在加一个自动备份网站数据和数据库的命令脚本就更完美了? 求指导给个思路和例举一下备份用到的几种方式.
天天手工备份很累. 我自己在用的，挺好的，加入crontab，每天三次可以备份多个数据库
三十天自动删除老的，信息自己修改吧。
#!/bin/sh
# mysql_backup.sh: backup mysql databases and keep newest 5 days backup.
# -----------------------------
db_user="root"
db_passwd="000000"
db_host="localhost"
# the directory for story your backup file.
backup_dir="/root/mysql_backup"
# date format for backup file (dd-mm-yyyy)
time="$(date +"%Y-%m-%d-%H:%M:%S")"
# mysql, mysqldump and some other bin's path
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
MKDIR="$(which mkdir)"
RM="$(which rm)"
MV="$(which mv)"
GZIP="$(which gzip)"
#针对不同系统，如果环境变量都有。可以去掉
# check the directory for store backup is writeable
test ! -w $backup_dir && echo "Error: $backup_dir is un-writeable." && exit 0
# the directory for story the newest backup
test ! -d "$backup_dir" && $MKDIR "$backup_dir"
# get all databases 设置数据库名
for db in abc cba
do
$MYSQLDUMP -u $db_user -h $db_host -p$db_passwd -e $db | $GZIP -9 > "$backup_dir/$time.$db.gz"
done
#delete the oldest backup 30 days ago
find $backup_dir -name "*.gz" -mtime +30 |xargs rm -rf
exit 0; 本来就写过，vpser.net 上搜一下
