为了确保数据的安全,我们往往要对数据进行备份。但是为了减少我们的工作量,我写了一个简单的数据备份工具,实现定时备份数据库。
其实程序很简单,数据备份的工作就是几个mysql的命令而已。
先看看程序的运行界面
可以看到界面是十分的简单的
我们使用的是命令行来进行数据备份,所以我们的程序需要一个能够执行命令行的函数
/// <summary> /// 执行Cmd命令 /// </summary> /// <param name="workingDirectory">要启动的进程的目录 /// <param name="command">要执行的命令 public static void StartCmd(String workingDirectory, String command) { Process p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.WorkingDirectory = workingDirectory; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.Start(); p.StandardInput.WriteLine(command); p.StandardInput.WriteLine("exit"); }
public void bakup_db() { try { //String command = "mysqldump --quick --host=localhost --default-character-set=gb2312 --lock-tables --verbose --force --port=端口号 --user=用户名 --password=密码 数据库名 -r 备份到的地址"; //构建执行的命令 StringBuilder sbcommand = new StringBuilder(); StringBuilder sbfileName = new StringBuilder(); sbfileName.AppendFormat("{0}", DateTime.Now.ToShortDateString()).Replace("-", "").Replace(":", "").Replace(" ", "").Replace("/", ""); String fileName = sbfileName.ToString(); String directory = bakpath + fileName+".bak"; sbcommand.AppendFormat("mysqldump --quick --host=localhost --default-character-set=utf8 --lock-tables --verbose --force --port=3306 --user={0} --password={1} {2} -r \"{3}\"", uname, upass, dbname, directory); String command = sbcommand.ToString(); //获取mysqldump.exe所在路径 //String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\"; StartCmd(appDirecroty, command); } catch (Exception ex) { } }
public void recovery_db() { //string s = "mysql --port=端口号 --user=用户名 --password=密码 数据库名<br> 为了实现定时备份,我们使用的是一个Timer组件,来实现定时的数据备份 <pre class="brush:php;toolbar:false">private void timer1_Tick(object sender, EventArgs e) { int h = DateTime.Now.Hour; if (h == hour) { bakup_db(); } }
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Diagnostics; namespace MysqlBak { public partial class Form1 : Form { //备份文件的路径 public String bakpath="d:\\db_bak\\"; public String appDirecroty = @"C:\Program Files (x86)\MySQL\MySQL Server 6.0\bin"; public String uname = "root"; public String upass = "root"; public String dbname = "losscar_db"; public int hour=18; public Form1() { InitializeComponent(); timer1.Interval=1000*10; timer1.Start(); txt_uname.Text = uname; txt_upass.Text = upass; txt_dbname.Text = dbname; txt_bakpath.Text = bakpath; txt_mysql.Text = appDirecroty; txt_hour.Text = hour.ToString(); } /// <summary> /// 执行Cmd命令 /// </summary> /// <param name="workingDirectory">要启动的进程的目录 /// <param name="command">要执行的命令 public static void StartCmd(String workingDirectory, String command) { Process p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.WorkingDirectory = workingDirectory; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.Start(); p.StandardInput.WriteLine(command); p.StandardInput.WriteLine("exit"); } private void btn_bak_Click(object sender, EventArgs e) { try { //String command = "mysqldump --quick --host=localhost --default-character-set=gb2312 --lock-tables --verbose --force --port=端口号 --user=用户名 --password=密码 数据库名 -r 备份到的地址"; //构建执行的命令 StringBuilder sbcommand = new StringBuilder(); StringBuilder sbfileName = new StringBuilder(); sbfileName.AppendFormat("{0}", DateTime.Now.ToShortDateString()).Replace("-", "").Replace(":", "").Replace(" ", "").Replace("/", ""); String fileName = sbfileName.ToString(); String directory = bakpath + fileName + ".bak"; sbcommand.AppendFormat("mysqldump --quick --host=localhost --default-character-set=utf8 --lock-tables --verbose --force --port=3306 --user={0} --password={1} {2} -r \"{3}\"", uname, upass, dbname, directory); String command = sbcommand.ToString(); //获取mysqldump.exe所在路径 //String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\"; StartCmd(appDirecroty, command); MessageBox.Show(@"数据库已成功备份到 " + directory + " 文件中", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show("数据库备份失败!"); } } public void bakup_db() { try { //String command = "mysqldump --quick --host=localhost --default-character-set=gb2312 --lock-tables --verbose --force --port=端口号 --user=用户名 --password=密码 数据库名 -r 备份到的地址"; //构建执行的命令 StringBuilder sbcommand = new StringBuilder(); StringBuilder sbfileName = new StringBuilder(); sbfileName.AppendFormat("{0}", DateTime.Now.ToShortDateString()).Replace("-", "").Replace(":", "").Replace(" ", "").Replace("/", ""); String fileName = sbfileName.ToString(); String directory = bakpath + fileName+".bak"; sbcommand.AppendFormat("mysqldump --quick --host=localhost --default-character-set=utf8 --lock-tables --verbose --force --port=3306 --user={0} --password={1} {2} -r \"{3}\"", uname, upass, dbname, directory); String command = sbcommand.ToString(); //获取mysqldump.exe所在路径 //String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\"; StartCmd(appDirecroty, command); } catch (Exception ex) { } } private void btn_recovery_Click(object sender, EventArgs e) { recovery_db(); } public void recovery_db() { //string s = "mysql --port=端口号 --user=用户名 --password=密码 数据库名
