]]>/usr/bin/mysqldump --opt -ubatsing -pbatsingpw -hlocalhost timepusher > /mnt/mysqlBackup/db_`date +%F`.sql
注解:
1、执行 /usr/bin/mysqldump
2、--opt是quick,add-drop-table,add-locks,extended-insert,lock-tables几个参数的合称,一般都要使用,具体意思自行搜索
3、-u数据库用户名 -p数据库用户密码 -h数据库地址 数据库名 > 导出的文件路径
4、date +%F
是shell中生成当前日期,格式如2015-11-05,所以成功导出时生成的文件名为 db_2015-11-05.sql
5、下载生成的 sql文件 ,用文本编辑器打开检查,本地导入测试数据库,看是否有问题
#!/bin/sh
# Database info
DB_USER="batsing"
DB_PASS="batsingpw"
DB_HOST="localhost"
DB_NAME="timepusher"
# Others vars
BIN_DIR="/usr/bin" #the mysql bin path
BCK_DIR="/mnt/mysqlBackup" #the backup file directory
DATE=`date +%F`
# TODO
# /usr/bin/mysqldump --opt -ubatsing -pbatsingpw -hlocalhost timepusher > /mnt/mysqlBackup/db_`date +%F`.sql
$BIN_DIR/mysqldump --opt -u$DB_USER -p$DB_PASS -h$DB_HOST $DB_NAME > $BCK_DIR/db_$DATE.sql
#还原数据库
#用mysql-front导入前一天的 *.sql 文件即可恢复数据
保存到文件或上传到 /usr/local/apache/htdocs/timepusher/sqlBak/sqlAutoBak.sh
1、进入到该脚本文件目录 chmod +x sqlAutoBak.sh 添加执行权限,否则会报错 Permission denied
2、./sqlAutoBak.sh ,如果是在windows编写上传的文件可能会报错
/bin/sh^M: bad interpreter: No such file or directory
这是不同系统编码格式引起的:在 windows系统中编辑的 .sh文件可能有不可见字符,所以在 Linux系统下执行会报以上异常信息。可以在Windows上使用Notepad++转换成Unix格式(菜单中选择:编辑>档案格式转换>转换成UNIX)
3、修改后上传继续执行 ./sqlAutoBak.sh ,没有报错。再查看导出的sql文件。
1、查看导出来的sql文件,发现其文件大小非常大,mysqldump也提供了生成gzip压缩文件的参数设置
2、sqlAutoBak.sh修改为如下
#!/bin/sh
# Database info
DB_USER="batsing"
DB_PASS="batsingpw"
DB_HOST="localhost"
DB_NAME="timepusher"
# Others vars
BIN_DIR="/usr/bin" #the mysql bin path
BCK_DIR="/mnt/mysqlBackup" #the backup file directory
DATE=`date +%F`
# TODO
# /usr/bin/mysqldump --opt -ubatsing -pbatsingpw -hlocalhost timepusher > /mnt/mysqlBackup/db_`date +%F`.sql
# $BIN_DIR/mysqldump --opt -u$DB_USER -p$DB_PASS -h$DB_HOST $DB_NAME > $BCK_DIR/db_$DATE.sql
$BIN_DIR/mysqldump --opt -u$DB_USER -p$DB_PASS -h$DB_HOST $DB_NAME | gzip > $BCK_DIR/db_$DATE.sql.zip
# 还原数据库
# 把 *.sql.zip 使用gunzip 或 本地的解压软件 解压为 *.sql 文件
# 用mysql-front导入前一天的 *.sql 文件即可恢复数据
3、修改后上传继续执行 ./sqlAutoBak.sh ,没有报错。如果用文本编辑器查看导出的 *.sql.gz文件,应该是一堆乱码。
4、下载到本地使用解压软件打开,解压就能看到里面真正的 *.sql 文件了。
1、编辑定时任务列表
crontab -e
2、插入下面这一行,因为通常来说5点钟网站的访问量最低
00 05 * * * /bin/sh /usr/local/apache/htdocs/timepusher/sqlBak/sqlAutoBak.sh
#每天早上 5:00am 执行
3、查看任务是否创建成功
crontab -l
如果生成的文件和解压出来查看没有问题,那么这个自动定时备份数据库的脚本就算是完成了。因为生成的文件多了会占用一定的空间,所以建议要定期(比如一个月)清理一下文件。
1、如果该数据库的用户没有分配 锁表 的权限,则备份会报错 when using LOCK TABLES 。那是因为mysqldump命令默认在导出时是要锁定表的,所以解决方式有两个。一个是给该用户开放 锁表 的权限;另一个是在命令中加上 --skip-lock-tables 这个参数。即是:
$BIN_DIR/mysqldump --opt -u$DB_USER -p$DB_PASS -h$DB_HOST $DB_NAME --skip-lock-tables | gzip > $BCK_DIR/db_$DATE.sql.gz
