安MariaDB

sudo apt-get install apt-transport-https curl

sudo curl -o /etc/apt/trusted.gpg.d/mariadb_release_signing_key.asc 'https://mariadb.org/mariadb_release_signing_key.asc'

sudo sh -c "echo 'deb https://mirrors.aliyun.com/mariadb/repo/10.10/debian buster main' >>/etc/apt/sources.list"

sudo apt-get update
sudo apt-get install mariadb-server

systemctl start mariadb

#如果你的MariaDB是10.4.6以下的版本,输入如下命令
mysql_secure_installation
#如果你的MariaDB是10.5.2以上的版本,输入如下命令
mariadb-secure-installation

#重启数据库
systemctl restart mariadb

#重新授权root用户：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' with grant option;
FLUSH PRIVILEGES;
 
#删除host为localhost的root用户：----->删除后必须刷新表的权限才生效
delete from mysql.user where host='localhost';
FLUSH PRIVILEGES;

安装配置Zabbix

a. 添加zabbix仓库

wget https://repo.zabbix.com/zabbix/6.0/debian/pool/main/z/zabbix-release/zabbix-release_6.0-4+debian10_all.deb

#官方源很慢，这里使用阿里云镜像
wget https://https://mirrors.aliyun.com/zabbix/6.0/debian/pool/main/z/zabbix-release/zabbix-release_6.0-4+debian10_all.deb
dpkg -i zabbix-release_6.0-4+debian10_all.deb

#修改zabbix镜像源
sed -i  "s/repo\.zabbix\.com/mirrors\.aliyun\.com\/zabbix/g" /etc/apt/sources.list.d/zabbix.list
sed -i  "s/repo\.zabbix\.com/mirrors\.aliyun\.com\/zabbix/g" /etc/apt/sources.list.d/zabbix-agent2-plugins.list

apt update

b. 安装 Zabbix server, frontend, agent

apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent

c. 创建数据库

使用root登录

create database zabbix_proxy character set utf8mb4 collate utf8mb4_bin; 

create user zabbix@localhost identified by 'password'; 

grant all privileges on zabbix.* to zabbix@localhost; 

set global log_bin_trust_function_creators = 1;

quit

将Zabbix server初始化数据导入数据库，这里使用的是上面创建的zabbix用户，需要输入zabbix的登录密码

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix_proxy

Disable log_bin_trust_function_creators option after importing database schema,使用root登录.

 set global log_bin_trust_function_creators = 0; 
 quit;

d. Configure the database for Zabbix server

#修改或者添加以下几项，其它按需处理
vi /etc/zabbix/zabbix_server.conf

ListenPort=10051
#ip改为本机ip
SourceIP=172.17.165.75
#密码为mariadb创建的zabbix用户密码
DBPassword=password
DBPort=3306

e. 开启Zabbix server 和agent服务（进程）

systemctl restart zabbix-server zabbix-agent apache2
systemctl enable zabbix-server zabbix-agent apache2

f. 开放防火墙打开浏览器访问输入本机ip/zabbix进行访问

如http://172.17.165.75/zabbix

iptables -I INPUT -p tcp --dport 80 -j ACCEPT
iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
iptables -I INPUT -p tcp --dport 10050 -j ACCEPT
#或者
firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --add-port=3306/tcp --permanent
firewall-cmd --add-port=10050/tcp --permanent
firewall-cmd --reload

配置Agent

1、安装Zabbix Agent

apt install zabbix-agent

2、配置 Zabbix Agent

vi /etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
DenyKey=system.run[*]
Server=172.17.165.80
ListenPort=10050
Hostname=prod server
Include=/etc/zabbix/zabbix_agentd.d/*.conf

3、启动 Zabbix Agetn

sudo systemctl start zabbix-agent.service

4、页面添加监控

http://172.17.165.80/zabbix

5、添加监控主机配置

6、添加监控项目，选择选择系统资源模板，也可以自行添加
