mysql root密码遗忘问题
# /etc/init.d/mysql stop
# mysqld_safe --skip-grant-tables&
mysql -u root -p
> UPDATE user SET password=PASSWORD('123456') WHERE user='root';
> flush privileges;
2.Zabbix alerter processes more than 75% busy
解决办法：
修改zabbix_server.conf配置文件
# vim /usr/local/zabbix/etc/zabbix_server.conf
将其默认值修改为：
StartPollers=20
# /etc/init.d/zabbix_server restart
3. 报错：Undefined index: lastfailedstep [dashboard.php:158 → make_webmon_overview() in /usr/local/nginx/html/zabbix/include/blocks.inc.php:1115]
问题原因：数据库删除历史数据导致
解决方案：删除所有web监控项，重新添加
