kingbase定时备份脚本

1、备份脚本

数据库定时备份脚本如下：

#cipt: this script is used for kingbase database backup,before you run it,you should set the variables such as
###         kdb_home,kdbback_dest,kdb_user,kdb_pass,kdb_host,kdb_port,kdb_list,keep_time and so on.
###
####################################################################################################################
####################### variable define ##########################
# 数据库安装目录
kdb_home="/opt/Kingbase/ES/V8/Server"
# 数据库备份的目标路径
kdbback_dest="/home/kingbaseback"
# 数据库用户名
kdb_user="SYSTEM"
# 数据库用户密码
kdb_pass="123123"
# 数据库端口号
kdb_port="54321"
# 数据库访问ip
kdb_host="222.74.1.41"
# 数据库的模式，多个模式可用逗号分隔，如"TEST,SAMPLE"
kdb_list="eng20210122"
# 保留时间
keep_time="7"

date=$(date '+%Y%m%d%H')
kdbback_final="${kdbback_dest}/kdbback_final"
LD_LIBRARY_PATH="${kdb_home}/unixodbc/lib:${kdb_home}/lib:${kdb_home}/bin"

####################### kingbase backup dest test ##################

[ -d ${kdbback_dest} ] || mkdir -p ${kdbback_dest}
[ -d ${kdbback_final} ] || mkdir -p ${kdbback_final}


####################### kingbase backup start  #######################

cd ${kdbback_dest}
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH
for db in `echo $kdb_list | sed 's/,/ /g'`; do
	[ -d ${db} ] || mkdir -p ${db}
        cd ${db}
	##### kingbase server check as follows
        ${kdb_home}/bin/ksql -h ${kdb_host} -p ${kdb_port} -U ${kdb_user} -W ${kdb_pass}  -c "select now();" TEMPLATE2 > /dev/null 2>&1
        if [ $? -ne 0 ] ;then
	    echo "${date} sorry, please run the script in a kingbase server" >> backup_${db}_${date}.log 
	    mv backup_${db}_${date}.log ${kdbback_final}
	    exit 1
        else
	    echo "${date} kingbase server is ok,kingbase backup ${db} is beginning ..." >> backup_${db}_${date}.log
        fi
	##### end
        ##### kingbase backup files process as follows
	${kdb_home}/bin/sys_dump -p ${kdb_port} -U ${kdb_user} -W ${kdb_pass} -h ${kdb_host} -f ${db}_${date}.dmp ${db} >> backup_${db}_${date}.log 2>&1
        if [ $? -eq 0 ] ;then
            tar zcvf ${db}_${date}.tar.gz ${db}_${date}.dmp*
            if [ $? -eq 0 ] ;then
               rm -f ${db}_${date}.dmp*
            else
               mv ${db}_${date}.dmp* ${kdbback_final} 
            fi
            find . -mtime +${keep_time} -name ${db}'_*' | xargs -I {} rm {}
        else
	    rm -f ${db}_${date}.dmp*
        fi
        ###### end
        ###### kingbase backup log files process as follows
	tar zcvf backup_log_${db}_${date}.tar.gz backup_${db}_${date}.log
        if [ $? -eq 0 ] ;then
	       rm -f backup_${db}_${date}.log
	else
	       mv backup_${db}_${date}.log ${kdbback_final}
        fi
        find . -mtime +${keep_time} -name backup_log_${db}'_*' | xargs -I {} rm {}
        ###### end
        cd ${kdbback_dest} 
done
exit 0

开启定时任务启动上面的脚本即可运行。

2、还原备份

还原命令如下：

./ksql -U用户名 -W密码 -d数据库名称 -p端口 -f 备份路径

例子如下：

./ksql -USYSTEM -W123456 -dtest -p54321 -f /home/lming/logical_dump_54321.dump

注意：以上脚本使用的是备份无法通过sys_restore命令来恢复。
