一、实现本地自动备份数据库很简单:
1.以root身份登陆
2.计划任务(每天的3:30自动执行 /usr/bin/mysqlbackup)
crontab
0 3:30 * * * /usr/bin/mysqlbackup
3.写一个自动备份数据库脚本
vi /usr/bin/mysqlbackup
#!/bin/bash
mv /home/.../db_bak5.tgz /home/.../db_bak6.tgz
mv /home/.../db_bak4.tgz /home/.../db_bak5.tgz
mv /home/.../db_bak3.tgz /home/.../db_bak4.tgz
mv /home/.../db_bak2.tgz /home/.../db_bak3.tgz
mv /home/.../db_bak1.tgz /home/.../db_bak2.tgz
rm -rf /home/.../db_bak.txt
/usr/bin/mysqldump -uroot -ppassword dbname
> /home/.../db_bak.txt
cd /home/.../
tar czvf db_bak1.tgz db_bak.txt
二、这样每天的3:30就会在本地目录/home/.../下生成相应的数据库备份,开始由于/home/.../目录下缺少数据系统会提示错误,这是正常的
三、至于远程备份可以配合使用ftp或scp命令实现,方法很简单,查一下相关命令的使用,然后再改动一下mysqlbackup脚本就可以了

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
