zabbix自定义监控、钉钉、邮箱报警（五十六）

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
yum install zabbix-server-mysql zabbix-agent
yum install centos-release-scl
vim /etc/yum.repos.d/zabbix.repo
####改这里
[zabbix-frontend]
...
enabled=1
...
 
yum install zabbix-web-mysql-scl zabbix-apache-conf-scl
 
yum -y install mariadb mariadb-server
systemctl start mariadb.service 
##进入MYSQL
mysql
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user "zabbix"@"localhost" identified by '123456';
mysql> grant all privileges on zabbix.* to "zabbix"@"localhost";
mysql> exit;
 
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
 
yum install zabbix-get
 
 
vim /etc/zabbix/zabbix_server.conf
##修改密码
DBPassword=123456
##揭开注释
DBHost=localhost

 
 
vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
php_value[date.timezone] = Asia/Shanghai
 
 
 
systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

zabbix-angent端：

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
yum install zabbix-agent


vim /etc/zabbix/zabbix_agentd.conf
##117行 
Server=192.168.156.148
##163行 
ServerActive=192.168.156.148
##174行 
Hostname=192.168.156.151
 
systemctl start zabbix-agent
systemctl enable zabbix-agent

二、安装

访问192.168.156.148/zabbix

三、添加监控对象

同理添加192.168.156.151

四、添加自定义监控项

在192.168.15.6151上添加自定义的监控项：监控当前登录用户的个数

vim /etc/zabbix/zabbix_agentd.d/user-login.conf
########定义键
########格式:UserParameter=key,shell命令（脚本也可）
UserParameter=user_login,who|wc -l
 
 
vim /etc/zabbix/zabbix_agentd.conf
###解开注释，启用
UnsafeUserParameters=1
 
systemctl restart zabbix-agent

yum -y install zabbix-get

在zabbix-server 上验证，数据采集没有问题了就可以添加监控项了

在web端添加自定义监控项

验证，使用ssh登录192.168.156.151，让登录用户大于3

五、监控mariadb

1、添加模版查看要求

在192.168.156.151上先

查看说明
