excel一些数据统计公式

平常时不时需要核对各种数据,比如两张表记录有何差异,多了哪个少了哪个,或者是一张小表需要从一张大表中提取信息,需要及时定位和统计出来。

1、双条件统计个数countif
=COUNTIFS(D$2:D$11,A16,B$2:B$11,”男”)
跨表查询如下:
=COUNTIFS(我的表1!D$2:D$11,A23,我的表1!B$2:B$11,”男”) 继续阅读“excel一些数据统计公式”

CentOS 7.6安装ELK 7.0.0(elasticsearch+kibana+logstash)

1、安装elk:elasticsearch+kibana+logstash

方法一:
使用elk官方的yum源,直接yum在线安装,缺点是网速很慢要等很久。

新增yum源elasticsearch
cat >>/etc/yum.repos.d/elasticsearch.repo <<EOF
[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=0
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

CentOS 7.6安装Cobbler 2.8.4

操作系统: CentOS7.6
cobbler:cobbler-2.8.4-4,IP地址为192.168.1.108

先关闭selinux和防火墙: firewalld selinux 关闭

1、安装

rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum install -y tftp-server httpd dhcp yum-utils cobbler cobbler-web cman debmirror xinetd rsync pykickstart fence-agents createrepo

解决web访问cobbler报错
yum install -y python2-pip
pip install Django==1.8.9

2、设置开机自启动

sed -i ‘/disable/c\\tdisable\t\t\t= no’ /etc/xinetd.d/tftp
sed -i -e ‘s/\=\ yes/\=\ no/g’ /etc/xinetd.d/rsync
systemctl enable cobblerd.service
systemctl enable dhcpd.service
systemctl enable httpd.service
systemctl enable xinetd.service
systemctl enable rsyncd.service 继续阅读“CentOS 7.6安装Cobbler 2.8.4”

VMware ESXI6批量配置snmp和snmptrap

需要对一大批esxi主机进行snmp监控,数量级在300+以上,纯手工一台台来配置snmp开启不现实,故用到vmware powercli进行批量开通。

团体名:mysnmpcomu123
snmptrap服务器地址:10.10.20.123
vcenter用户名密码:admin123@my.vmware/ zzzxxx123
vcenter地址:10.10.10.4
目的:设置snmp后,执行snmpwalk -v 2c -c mysnmpcomu123 10.10.10.119 system会有反馈。设置snmptrap后,snmptrap服务器可以收到esxi反馈的数据。 继续阅读“VMware ESXI6批量配置snmp和snmptrap”
