用于生产环境的几个备份shell脚本

用于生产环境的四个shell备份脚本，分别是批量备份多个数据库、备份网站目录、目录rsync同步、nginx日志切割。

生产环境中的备份shell脚本，共四个，供大家学习参考。

1，批量备份多个数据库

复制代码代码示例:

#!/bin/bash
BACKUP_HOST="localhost"
BACKUP_USER="root"
BACKUP_PASS="123456"
BACKUP_DIR="/backup/mysql"
BACKUP_DBNAME="one two three"

COPIES=10

MYSQLDUMP="mysqldump"
TIMEPOINT=$(date +%Y-%m-%d)
MYSQLDUMP_OPTS="-h $BACKUP_HOST -u$BACKUP_USER -p$BACKUP_PASS"

umask 0077

test ! -d "$BACKUP_DIR" && mkdir -p "$BACKUP_DIR"
test ! -w $BACKUP_DIR && echo "Error: $BACKUP_DIR is un-writeable." && exit 0

for dbname in $BACKUP_DBNAME
do
test ! -d "$BACKUP_DIR/$dbname" && mkdir -p "$BACKUP_DIR/$dbname"
$MYSQLDUMP $MYSQLDUMP_OPTS $dbname | gzip > $BACKUP_DIR/$dbname/$dbname.$TIMEPOINT.sql.gz
done

find $BACKUP_DIR -type f -mtime +$COPIES -delete

2，网站目录备份

复制代码代码示例:

#!/bin/bash
#edit www.jbxue.com
BACKUP_DIR=/backup/website
WEBSITE_DIR=/www
TIMEPOINT=$(date +%Y-%m-%d)
COPIES=10

test ! -d "$BACKUP_DIR" && mkdir -p "$BACKUP_DIR"
test ! -w $BACKUP_DIR && echo "Error: $BACKUP_DIR is un-writeable." && exit 0

umask 0077

tar -zcf $BACKUP_DIR/www.$TIMEPOINT.tar.gz $WEBSITE_DIR

find $BACKUP_DIR -type f -mtime +$COPIES -delete

3，目录rsync同步(需先安装配置rsync)

复制代码代码示例:

#!/bin/sh
srcdir1=/www/example1.com
srcdir2=/www/example2.com

dstdir3=jszb@111.111.111.111::example1
dstdir4=jszb@222.222.222.222::example2

rsync -avz --delete --progress --password-file=/backup/bash/rsync.pas $srcdir1 $dstdir3 &
rsync -avz --delete --progress --password-file=/backup/bash/rsync.pas $srcdir2 $dstdir4 &

4，nginx日志切割

复制代码代码示例:

	#!/bin/bash

	#edit www.jbxue.com

	logs_path="/usr/local/webserver/nginx/logs/"

	mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/

	mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log

	kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
