Zabbix备份数据文件
mysql自带的工具mysqldump，当数据量大了之后进行全备所花的时间比较长，这样将会造成数据库的锁读、从而zabbix服务的监控告警不断，想着做下配置文件的备份、刚好有这么个脚本、满足了需求。
后续会使用xtrabckup来进行完成备份，执行这个脚本所花时间不过几秒

执行步骤如下
[root@Zabbix-Server /]# sh zabbix-datafile-bak.sh mysqldump [root@Zabbix-Server /]# ls bin dev home lib64 mnt proc run srv tmp var zabbix-datafile-backup boot etc lib media opt root sbin sys usr zabbix-data-backup zabbix-datafile-bak.sh [root@Zabbix-Server /]# cd zabbix-datafile-backup/ [root@Zabbix-Server zabbix-datafile-backup]# ls 20180109 logs [root@Zabbix-Server zabbix-datafile-backup]# cd 20180109/ [root@Zabbix-Server 20180109]# ls actions.sql graphs.sql interface_discovery.sql opinventory.sql slideshow_usrgrp.sql application_discovery.sql graph_theme.sql interface.sql opmessage_grp.sql slides.sql application_prototype.sql group_discovery.sql item_application_prototype.sql opmessage.sql sysmap_element_url.sql applications.sql group_prototype.sql item_condition.sql opmessage_usr.sql sysmaps_elements.sql application_template.sql groups.sql item_discovery.sql optemplate.sql sysmaps_links.sql autoreg_host.sql host_discovery.sql items_applications.sql profiles.sql sysmaps_link_triggers.sql conditions.sql host_inventory.sql items.sql proxy_autoreg_host.sql sysmaps.sql config.sql hostmacro.sql maintenances_groups.sql regexps.sql sysmap_url.sql dbversion.sql hosts_groups.sql maintenances_hosts.sql rights.sql sysmap_user.sql dchecks.sql hosts.sql maintenances.sql screens_items.sql sysmap_usrgrp.sql dhosts.sql hosts_templates.sql maintenances_windows.sql screens.sql timeperiods.sql drules.sql housekeeper.sql mappings.sql screen_user.sql trigger_depends.sql dservices.sql httpstepitem.sql media.sql screen_usrgrp.sql trigger_discovery.sql escalations.sql httpstep.sql media_type.sql scripts.sql triggers.sql expressions.sql httptestitem.sql opcommand_grp.sql services_links.sql users_groups.sql functions.sql httptest.sql opcommand_hst.sql services.sql users.sql globalmacro.sql icon_mapping.sql opcommand.sql services_times.sql usrgrp.sql globalvars.sql icon_map.sql opconditions.sql sessions.sql valuemaps.sql graph_discovery.sql ids.sql operations.sql slideshows.sql graphs_items.sql images.sql opgroup.sql slideshow_user.sql
加入计划任务、每天可以执行一次
[root@Zabbix-Server zabbix]# crontab -l|tail -2 #Q-2018-1/9 00 6 * * * /etc/zabbix/zabbix-datafile-bak.sh mysqldump
重启下计划任务服务
/sbin/service crond restart
