部署Zabbix4.0和Grafana

一、Zabbix

1、安装

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum clean all

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent

2、安装数据库

推荐直接使用centos的mariaDB，先进行数据库初始化

# 后面的yes/no自己甄别，推荐先不创建root密码
mysql_secure_installation
...

3、初始化数据库

# 进入数据库【password】为自定义密码
mysql
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by '【password】';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit;

# 导入初始架构和数据，系统将提示您输入新创建的密码。
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p【password】 zabbix

# 为Zabbix server配置数据库
vim /etc/zabbix/zabbix_server.conf
...
DBPassword=【password】
...

4、初始化zabbix-server

# 设置自己的时区
vim /etc/httpd/conf.d/zabbix.conf
...
php_value date.timezone Asia/Shanghai
...

# 启动Zabbix server和agent进程，并为它们设置开机自启
systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd

# 连接到新安装的Zabbix前端： http://server_ip_or_name/zabbix
# 然后按照网页上的提示进入zabbix
# 默认用户密码为：Admin/zabbix

5、创建一个zabbix-agent

# 这里使用yum安装
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum clean all
yum install -y zabbix-agent

# 修改agent配置文件中对应的server地址
vim /etc/zabbix/zabbix_agentd.conf 
...
# Mandatory: yes, if StartAgents is not explicitly set to 0
# Default:
# Server=

Server=对应的zabbix-server的ip
...

# 启动agent
systemctl start zabbix-agent
systemctl enable zabbix-agent

6、在server端添加zabbix-agent

到此zabbix-server和zabbix-agent已经安装好了

二、Grafana

1、安装

wget https://dl.grafana.com/oss/release/grafana-7.5.5-1.x86_64.rpm
yum install grafana-7.5.5-1.x86_64.rpm
systemctl enable grafana-server.service
systemctl start grafana-server.service

浏览器打开3000端口，默认账户密码是admin/admin

2、安装zabbix插件

grafana-cli plugins install alexanderzobnin-zabbix-app
systemctl restart grafana-server.service

插件中就会出现

3、添加zabbix数据源

添加后即可

4、查看dashboard
