一、Zabbix介绍
Zabbix是一个监控系统，它可以帮助我们实时检查设备的状态，比如服务器、网络设备等。当设备出现问题时，它会及时通知我们，让我们可以采取措施来解决。同时，它还可以把收集到的数据转化成图表和报告，让我们更直观地了解设备的运行情况
1、监控的作用
任何你所想要监控的数据, 如cpu负载,cpu的idle时间,内存使用量,内存利用率,io,network等等。
现在很多开源监控方案已经把常见的监控做成了模板，我们可以直接套用
大型公司会有更多的监控需求, 那么就需要专业的开发人员来做监控开发(运维人员也可以开发）
2、zabbix特性
数据采集
Zabbix Agent方式会定期收集设备的各种指标数据，比如CPU使用率、内存占用、网络流量等。这些数据会被Zabbix Server主动获取。
触发检测告警
Zabbix会根据我们事先设定的阈值和触发条件，对采集到的数据进行检测。如果某个指标超过了阈值或满足了触发条件，Zabbix会触发一个告警。Zabbix会根据事先设置的通知方式，比如邮件、短信等，通知相关的人员或团队。这样我们可以及时知道设备出现了问题。
数据存储
Zabbix将采集到的数据存储在数据库中
数据展示
Zabbix提供了丰富的可视化功能，可以将采集到的数据转化成各种图表和报表。这样我们可以直观地了解设备的运行状态和趋势。
3、zabbix结构
Zabbix-server：收集监控数据，计算是否满足触发条件，向用户发送通知
Zabbix-database：所有配置信息和Zabbix收集到的数据都被存储在数据库中
Zabbix-Web：为了在任何地方和任何平台都能轻松地访问Zabbix，Zabbix提供了基于Web的界面。该界面是Zabbix Server的一部分，通常跟Zabbix Server运行在同一台物理机器上。
Zabbix-proxy：Zabbix Proxy可以替Zabbix Server收集性能和可用性数据。Proxy代理服务器是Zabbix 软件可选择部署的一部分。当然，Proxy代理服务器可以帮助单台Zabbix Server分担负载压力。
Zabbix-agent：Zabbix Agents监控代理部署在监控目标上，主动监控本地资源和应用(硬件驱动，内存等)
4、主流的开源监控平台介绍
mrtg (Multi Router Traffic Grapher)

二、安装zabbix
环境：rocky Linux 9虚拟机一台，selinux与firewalld均已关闭，使用Xshell连接
1、安装工具包
[root@zabbix ~]# yum -y install lrzsz tar net-tools chrony
//时钟同步
[root@zabbix ~]# systemctl restart chronyd
[root@zabbix ~]# systemctl enable chronyd
[root@zabbix ~]# hwclock -w
2、配置zabbix源
//将包文件直接拖进来
[root@zabbix ~]# rz -E
rz waiting to receive.
[root@zabbix ~]# ls
anaconda-ks.cfg zabbix-release-7.0-2.el9.noarch.rpm
[root@zabbix ~]# rpm -Uvh zabbix-release-7.0-2.el9.noarch.rpm
warning: zabbix-release-7.0-2.el9.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID b5333005: NOKEY

1:zabbix-release-7.0-2.el9 ################################# [100%]
将zabbix的源换成阿里源
[root@zabbix ~]# vim /etc/yum.repos.d/zabbix.repo
//将该文件内容替换为以下内容
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/7.0/rocky/9/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-B5333005
[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/non-supported/rhel/9/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-08EFA7DD

[zabbix-sources]
name=Zabbix Official Repository source code - $basearch
baseurl=https://repo.zabbix.com/zabbix/7.0/rocky/9/SRPMS
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-B5333005
gpgcheck=1
在epel源后面添加一行
[root@zabbix ~]# vim /etc/yum.repos.d/epel.repo
//在[epel]这个标签的末尾加上一行信息，否则安装会报错
[epel]
......
excludepkgs=zabbix*
3、安装zabbix、web前端、agent、数据库包文件
[root@zabbix ~]# yum install zabbix-server-mysql zabbix-web-mysql zabbix-nginx-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent mariadb-server mariadb -y
4、启动并初始化数据库
//启动数据库
[root@zabbix ~]# systemctl restart mariadb
[root@zabbix ~]# systemctl enable mariadb
//初始化数据库
[root@zabbix ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
You already have your root account protected, so you can safely answer 'n'.
Switch to unix_socket authentication [Y/n] y
Enabled successfully!
Reloading privilege tables..
... Success!
You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] y
New password: 输入密码
Re-enter new password: 再次输入密码
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
5、配置数据库并导入zabbix表数据
[root@zabbix ~]# mysql -uroot -predhat
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 12
Server version: 10.5.22-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> create database zabbix character set utf8mb4 collate utf8mb4_bin;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> create user zabbix@localhost identified by 'redhat';
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global log_bin_trust_function_creators = 1;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> exit
Bye
[root@zabbix ~]# zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix
Enter password: //这里输入数据库密码
6、导入数据库架构后禁用log_bin_trust_function_creators选项
[root@zabbix ~]# myaql -uroot -predhat
bash: myaql: command not found
[root@zabbix ~]# mysql -uroot -predhat
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 14
Server version: 10.5.22-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> set global log_bin_trust_function_creators = 0;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> exit
Bye
7、配置zabbix并启动服务
[root@zabbix ~]# vim /etc/zabbix/zabbix_server.conf
//找到并修改以下内容，内容一样的去掉#
//内容不一样就修改并去掉#
ListenPort=10051
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=redhat
DBSocket=/var/lib/mysql/mysql.sock
ListenIP=0.0.0.0
8、zabbix配置启动服务—浏览器访问
//编辑配置文件 /etc/nginx/conf.d/zabbix.conf 取消注释并设置“listen”和“server_name”指令
[root@zabbix ~]# vim /etc/nginx/conf.d/zabbix.conf
listen 8080;
server_name example.com;
//启动以下服务并enable
[root@zabbix ~]# systemctl restart zabbix-server zabbix-agent nginx php-fpm
[root@zabbix ~]# systemctl enable zabbix-server zabbix-agent nginx php-fpm
//浏览器访问http://192.168.100.115:8080/setup.php
注：ip换成自己的
9、解决支持中文
[root@zabbix ~]# yum -y install langpacks-zh_CN.noarch glibc-common
[root@zabbix ~]# locale -a | grep zh_CN
zh_CN
zh_CN.gb18030
zh_CN.gbk
zh_CN.utf8
然后刷新浏览器
10、设置浏览器界面
下一步再接完成就配置好了，就可以进入登陆界面了
默认账号为Admin，密码为zabbix
11、解决中午乱码问题
找到windows下的简体 楷体 常规字体
C:\Windows\Fonts
将简体 楷体 常规字体文件复制出来上传到Linux系统中的/usr/share/zabbix/assets/fonts
替换原先的字体文件即可
[root@zabbix ~]# cd /usr/share/zabbix/assets/fonts/
[root@zabbix fonts]# rz -E
rz waiting to receive.
[root@zabbix fonts]# ls
graphfont.ttf SIMKAI.TTF zabbix-icons.svg zabbix-icons.ttf zabbix-icons.woff zabbix-icons.woff2
[root@zabbix fonts]# mv SIMKAI.TTF graphfont.ttf
mv: overwrite 'graphfont.ttf'? y
12、监控远程主机
//新开一台虚拟机
[root@node6 ~]# rz -E
rz waiting to receive. //将包文件拖进来
[root@node6 ~]# rpm -Uvh zabbix-release-7.0-2.el9.noarch.rpm
warning: zabbix-release-7.0-2.el9.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID b5333005: NOKEY

Server=192.168.100.40 zabbix服务器的IP，agent被动监控(默认模式)
ServerActive=192.168.100.40 zabbix服务器的IP，agent主动监控
Hostname=zabbix-agent zabbix服务器的主机名
[root@node6 ~]# systemctl restart zabbix-agent
[root@node6 ~]# systemctl enable zabbix-agent
完成
