定时备份mysql, 定时切割nginx access log的方法，需要的朋友可以参考下。
定时备份mysql放入 /etc/cron.hourly/
代码如下:
#!/bin/bash
DUMP=/usr/local/webserver/mysql/bin/mysqldump
OUT_DIR=/data1/backup/
DB_NAME=数据库名
DB_USER=数据库用户
DB_PASS=数据库密码
#How much days backup most
DAYS=3
#12 hours ago
MINS=720
#Core of script
cd $OUT_DIR
DATE=`date +%Y-%m-%d-%H`
OUT_SQL="$DATE.sql"
TAR_SQL="db-$DATE.tar.gz"
$DUMP --default-character-set=utf8 --opt -u$DB_USER -p$DB_PASS $DB_NAME > $OUT_SQL
tar -czf $TAR_SQL ./$OUT_SQL
rm -f $OUT_SQL
find ./ -name "db*" -type f -mmin +$MINS -exec rm {} \;
#find ./ -name "db*" -type f -mtime +$DAYS -exec rm {} \;
exit 0;
定时切割nginx access.log，只保留3天前的记录
放入 /etc/cron.hourly/
代码如下:
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
#logs_path="/usr/local/webserver/nginx/logs/"
logs_path="/data1/logs/"
#How much days backup most
DAYS=3
#Core of script
cd $logs_path
DATE=`date +%Y-%m-%d-%H`
SRC_FILE="access.log"
TAR_FILE="access-$DATE.tar.gz"
tar -czf $TAR_FILE $SRC_FILE
rm -f $SRC_FILE
find ./ -name "access-*" -type f -mtime +$DAYS -exec rm {} \;
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
exit 0;
