本篇文章介绍zabbix监控，监控是对我们操作系统进行不间断的监控，这是软件生命周期非常重要的一环，可以做到事前告警，事后根据监控内容排查问题（金丝雀，监控重要指标），有问题的时候，运维需要管理运维债务（在软件开发过程中积累的一些技术债务）
1.监控内容
我们需要监控硬件（磁盘df -h，内存free，磁盘IO，负载CPU，网络），软件服务（端口、进程、状态），业务层面（监控业务数据，订单量，注册用户，充值用户），只要是有值，zabbix都能监控，核心功能就是自定义监控。
2.监控工具
Nagions 网络产品 交换机 路由器 中型大型公司使用
Cacti 流量
Open-Falcon 小米公司自研
prometheus 监控kubernetes docker，比zabbix更好
监控宝等等
3.Zabbix安装
服务端：10.0.0.71（配置与监控数量有关，企业中一般是8G内存，4核或6核）
客户端：10.0.0.7，10.0.0.8
系统版本为CentOS7.9
（1）配置yum源
rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
yum clean all（2）安装zabbix服务
yum -y install zabbix-server-mysql zabbix-agent（3）安装scl源，更好的兼容已经安装的软件包，避免把系统搞烂
yum -y install centos-release-scl（4）开启前端的仓库
[root@Zabbix ~]# cat /etc/yum.repos.d/zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/

baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1（5）安装php和apache前端
yum -y install zabbix-web-mysql-scl zabbix-apache-conf-scl（6）安装mariadb
yum -y install mariadb-server
systemctl start mariadb
systemctl enable mariadb[root@Zabbix ~]# mysql -uroot

4.Zabbix添加监控服务器
（1）安装zabbix-agent客户端，准备一台服务器10.0.0.7
#配置yum仓库
rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-agent-5.0.34-1.el7.x86_64.rpm
#解决软件冲突
yum -y install centos-release-scl
#安装客户端agent
yum -y install zabbix-agent（2）配置zabbix客户端服务器信息，启动服务端
[root@Web01 yum.repos.d]# cat /etc/zabbix/zabbix_agentd.conf
Server=172.16.1.71
[root@Web01 yum.repos.d]# systemctl start zabbix-agent
5.拆分数据库
（1）准备一台数据库服务器10.0.0.51安装mariadb
[root@DB01 ~]# yum -y install mariadb-server
[root@DB01 ~]# systemctl start mariadb
[root@DB01 ~]# systemctl enable mariadb
[root@DB01 ~]# mysql

[root@Zabbix ~]# mysqldump -uroot -B zabbix > zabbix.sql
[root@Zabbix ~]# cat zabbix.sql |mysql -h 172.16.1.51 -uzabbix -pzabbix zabbix（3）配置WEB连接数据库信息并重启服务
[root@Zabbix ~]# cat /etc/zabbix/web/zabbix.conf.php
<?php
// Zabbix GUI configuration file.$DB['TYPE'] = 'MYSQL';
$DB['SERVER'] = '172.16.1.51';
$DB['PORT'] = '3306';
$DB['DATABASE'] = 'zabbix';
$DB['USER'] = 'zabbix';
$DB['PASSWORD'] = 'zabbix';
