Linux服务器制定mysql数据库备份的计划任务

首先，创建一个shell脚本：

Shell

#!/bin/bash
mysql_pwd="1234567890"
mysql_dump="/usr/local/mysql/bin/mysqldump"
cur_year=$(date +"%Y")
cur_month=$(date +"%m")
cur_day=$(date +"%d")
#dump_path="/data0/mysql_backup/$cur_year-$cur_month/$cur_day"
arr_databases=(
"db1"
"db2"
"db3"
"db4"
)

for cur_database in ${arr_databases[*]}; do
#mkdir backup path
dump_path="/data0/mysql_backup/$cur_database"
if [ ! -d "$dump_path" ]; then
mkdir -p "$dump_path"
fi
#backup database
$mysql_dump -uroot -p$mysql_pwd $cur_database | gzip > $dump_path/$cur_database-$cur_year-$cur_month-$cur_day.sql.gz
#Delete backup files 10 days ago
cd $dump_path
rm -rf `find . -name '*.sql.gz' -mtime 20`
done

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#!/bin/bash mysql_pwd="1234567890" mysql_dump="/usr/local/mysql/bin/mysqldump" cur_year=$(date +"%Y") cur_month=$(date +"%m") cur_day=$(date +"%d") #dump_path="/data0/mysql_backup/$cur_year-$cur_month/$cur_day" arr_databases=( "db1" "db2" "db3" "db4" )   for cur_database in ${arr_databases[*]}; do #mkdir backup path dump_path="/data0/mysql_backup/$cur_database" if [ ! -d "$dump_path" ]; then mkdir -p "$dump_path" fi #backup database $mysql_dump -uroot -p$mysql_pwd $cur_database | gzip > $dump_path/$cur_database-$cur_year-$cur_month-$cur_day.sql.gz #Delete backup files 10 days ago cd  $dump_path rm -rf `find . -name '*.sql.gz' -mtime 20` done

可以保存到路径：/data0/scripts/backup_database.sh

#设置可执行权限
cd /data0/scripts/
chmod +x *

1 2 3

#设置可执行权限 cd /data0/scripts/ chmod +x *

添加计划任务

vi /etc/crontab
#添加命令：
01 1 * * * root /data0/scripts/backup_database.sh #每天的01点01分执行
20 2 * * 0 root /data0/scripts/backup_database.sh #每周星期天的02点20分执行
#重启服务
/sbin/service crond restart

1 2 3 4 5 6

vi /etc/crontab #添加命令： 01 1 * * * root /data0/scripts/backup_database.sh  #每天的01点01分执行 20 2 * * 0 root /data0/scripts/backup_database.sh  #每周星期天的02点20分执行 #重启服务 /sbin/service crond restart

完事大吉！
