問(wèn)題一：

/usr/local/bin/mysqlbinlog --start-datetime="2018-08-24 16:33:57" --stop-datetime="2018-08-24 16:34:36" mysql-bin.000037 > abc.sql

mysql-bin.000037文件不帶時(shí)間直接使用mysqlbinlog導(dǎo)出，數(shù)據(jù)為

那么問(wèn)題來(lái)了

開(kāi)始時(shí)間為2018-08-24 16:33:57,那abc.sql文件中為啥有180824 16:24:46這個(gè)時(shí)間點(diǎn)的

結(jié)束時(shí)間為2018-08-24 16:34:36,那abc.sql文件中為啥沒(méi)有180824 16:34:36這個(gè)時(shí)間點(diǎn)的

問(wèn)題二

mac os下關(guān)于date時(shí)間函數(shù)問(wèn)題

我寫了一個(gè)腳本，用作，輸入時(shí)間點(diǎn)進(jìn)行binlog回滾點(diǎn)，時(shí)間點(diǎn)使用參數(shù)形式傳進(jìn)去后，是一個(gè)字符串的形式，我想把這個(gè)字符串轉(zhuǎn)為時(shí)間類型，不知要如何轉(zhuǎn)，試了幾種方式，不得其法。

我的大概腳本內(nèi)容

incre_recov(){

echo '增量回滾數(shù)據(jù)，需要三個(gè)參數(shù)，binlog 文件，start-datetime，stop-datetime'

echo 'start-datetime 格式為："2018-08-23 14:01:00"，此處為雙引號(hào)'

echo $#

if [ $# != 6 ];then

echo "參數(shù)數(shù)量不對(duì)"

else

echo '$1' + 'is' + $1

echo '$2' + 'is' + "$2"

echo '$3' + 'is' + "$3"

echo '$4' + 'is' + "$4"

echo '$5' + 'is' + "$5"

echo '$6' + 'is' + "$6"

start_time=`date -j -f "%Y-%m-%d %H:%M:%S" "$3 $4" "+%s"`

end_time=`date -j -f "%Y-%m-%d %H:%M:%S" "$5 $6" "+%s"`

${MysqlPath}/mysqlbinlog --start-datetime="$start_time" --stop-datetime=="$end_time" $2 > abc.sql

echo "${MysqlPath}/mysqlbinlog --start-datetime="$start_time" --stop-datetime="$end_time" $2 > abc.sql"

fi

case "$1" in

incre_recov)

incre_recov $*

;;

*)

echo "$0 [incre_recov]"

exit 0

esac

}

腳本運(yùn)行結(jié)果

sos:work_shell apple$ sh MysqlFullBack.sh incre_recov /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037 "2018-08-24 16:33:57" "2018-08-24 16:34:36"

增量回滾數(shù)據(jù)，需要三個(gè)參數(shù)，binlog 文件全路徑，start-datetime，stop-datetime

start-datetime 格式為："2018-08-23 14:01:00"，此處為雙引號(hào)

$1 + is + incre_recov

$2 + is + /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037

$3 + is + 2018-08-24

$4 + is + 16:33:57

$5 + is + 2018-08-24

$6 + is + 16:34:36

ERROR: Incorrect date and time argument: 1535099637

/usr/local/bin/mysqlbinlog --start-datetime=1535099637 --stop-datetime=1535099676 /Users/apple/work_shell/incre_backup/20180824/mysql-bin.000037 > abc.sql

按照mysqlbin --help這里--start-datetime和--stop-datetime=，格式要為DATETIME and TIMESTAMP才行

那么我這個(gè)傳進(jìn)去的起止時(shí)間要怎么處理？
