摘要:上面是备份的结果,注意,备份完了之后是压缩包的形式,所以请你先安装压缩工具,不会的还是麻烦百度下,实在简单成狗了。
前几篇博客已经相继公开了去转盘网的所有技术细节,如下:
百度网盘爬虫
中文分词算法

js分页部分代码
这篇博客我将继续公开数据库自动备份的代码。可以这么说,没有数据库,一切就是个蛋,没有数据库备份,一切还是个蛋,你可以想象数据库备份多么重要。不会linux,不会写shell的朋友麻烦先去补补。不过你说我牛逼,不补也能看懂,那没问题,哈哈,废话不说了。老规矩,上代码:
#!/bin/bash time=$(date +"%d-%m-%Y") pre=/home/ubuntu #想放到那里麻烦自己配置下哈 if [ ! -d "$pre/data_backup/$time" ] then mkdir -p $pre/data_backup/$time echo "create $pre/data_backup/$time" else echo "exist $pre/data_backup/$time" fi if [ -d "$pre/data_backup/$time" ] then mysqldump -h10.66.102.75 -uroot -p123456 --opt winrun user > $pre/data_backup/$time/user.sql mysqldump -h10.66.102.75 -uroot -p123456--opt winrun CategoryInfo > $pre/data_backup/$time/CategoryInfo.sql mysqldump -h10.66.102.75 -uroot -p123456 --opt winrun admin_info > $pre/data_backup/$time/admin_info.sql mysqldump -h10.66.102.75 -uroot -p123456 --opt winrun admin_loginfo > $pre/data_backup/$time/admin_loginfo.sql mysqldump -h10.66.102.75 -uroot -p123456 --opt winrun admin_notice_info > $pre/data_backup/$time/admin_notice_info.sql mysqldump -h10.66.102.75 -uroot -p123456--opt winrun advertising_info > $pre/data_backup/$time/advertising_info.sql mysqldump -h10.66.102.75 -uroot -p123456--opt winrun ajax_request_info > $pre/data_backup/$time/ajax_request_info.sql mysqldump -h10.66.102.75 -uroot -p123456 --opt winrun bt_file_info > $pre/data_backup/$time/bt_file_info.sql echo "backup finished" cd $pre/data_backup #enter dir zip -r $time.zip $time/ rm -fr $time #delete cd - echo "zip backup database finished" else echo "can not find backup file" fi
注意,我的密码我已经改了,这个不能告诉你们,所以喜欢copy的孩子麻烦自己该密码。下面我教大家玩下crotab,代码如下:
# Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use "*" in these fields (for "any").# # Notice that tasks will be started based on the cron"s system # daemon"s notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command 10 1 * * 1,3,5 /home/backup.sh >> /home/backup.log
有用的是最下面的这一句,看到没有,备份完了还得有个log,不然谁知道备份成什么样子了,一点都不懂crontab麻烦自己百度下,我也一时给你讲不明白。
上面是备份的结果,注意,备份完了之后是压缩包的形式,所以请你先安装压缩工具,apt-get install XXXX 不会的还是麻烦百度下,实在简单成狗了。
