2022-01-24 22:25:42

这里使用的的yum安装的

先关闭selinux和防火墙，然后重启服务器。

安装zabbix

#下载yum源
wget http://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

#安装源码库
rpm -ivh zabbix-release-4.4-1.el7.noarch.rpm

#安装Zabbix部署包
yum -y install zabbix-agent zabbix-get zabbix-server-mysql zabbix-sender zabbix-web zabbix-web-mysql

安装数据库

#下载mysql源码包
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

#安装mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm -y

#安装MySQL5.7
yum install mysql-community-server -y

#启动服务
systemctl  enable --now mysqld

#修改root本地登录密码
#mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码.
[root@localhost ~]# grep 'password' /var/log/mysqld.log
2021-11-19T17:21:41.433493Z 1 [Note] A temporary password is generated for root@localhost: QjEg/pll6N(c

#登录mysql修改密码
#mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位
[root@localhost ~]# mysql -uroot -p
Enter password:

+----------------------------------------+-----------------+
validate_password_policy：密码策略，默认为MEDIUM策略 
validate_password_dictionary_file：密码策略文件，策略为STRONG才需要 
validate_password_length：密码最少长度 
validate_password_mixed_case_count：大小写字符长度，至少1个 
validate_password_number_count ：数字至少1个 
validate_password_special_char_count：特殊字符至少1个 

#修改密码策略
在/etc/my.cnf文件添加validate_password_policy配置，指定密码策略
选择0（LOW），1（MEDIUM），2（STRONG）其中一种，选择2需要提供密码字典文件
validate_password_policy=0
如果不需要密码策略，添加my.cnf文件中添加如下配置禁用即可
validate_password = off
重新启动mysql服务使配置生效

修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置

vim /etc/my.cnf
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'

#重启服务，查看数据库默认编码
systemctl restart mysqld

[root@localhost ~]# mysql -uroot -pPasswd123! -e "show variables like '%character%'"

导入zabbix建库脚本

cd /usr/share/doc/zabbix-server-mysql-4.4.10/

zcat create.sql.gz| mysql -uzabbix -pzabbix zabbix

启动Zabbix Server

在zabbix_server.conf中编辑数据库配置

vim /etc/zabbix/zabbix_server.conf
#添加配置
DBHost=192.168.248.135
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

#启动服务
systemctl  enable --now zabbix-server

配置web GUI

#Zabbix前端的Apache配置文件位于/etc/httpd/conf.d/zabbix.conf 
vim /etc/httpd/conf.d/zabbix.conf

        php_value date.timezone Asia/Shanghai #修改时区
        </IfModule>

#启动服务
systemctl  enable --now httpd

安装grafana

官方：https://grafana.com/grafana/download

#下载包
 wget https://dl.grafana.com/enterprise/release/grafana-enterprise-7.1.1-1.x86_64.rpm

#安装
yum -y install grafana-enterprise-7.1.1-1.x86_64.rpm 
#启动服务
systemctl  enable --now grafana-server

测试访问 ip:300

默认用户和密码：admin admin

安装garfana-zabbix插件

#过滤出zabbix插件
[root@localhost ~]# grafana-cli plugins list-remote|grep zabbix
id: alexanderzobnin-zabbix-app version: 4.0.2

#安装zabbix插件
grafana-cli plugins install alexanderzobnin-zabbix-app

下载地址https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app/

[root@localhost ~]# ls /var/lib/grafana/plugins/
alexanderzobnin-zabbix-app-4.0.2.zip

#解压缩
cd /var/lib/grafana/plugins/
unzip alexanderzobnin-zabbix-app-4.0.2.zip

#重启grafana服务
 systemctl  restart grafana-server

登录到grafana上，启用插件

添加新数据源

添加数据源时，会发现找不到zabbix 修改grafana的配置，将zabbix插件配置允许找到 “;allow_loading_unsigned_plugins =“ 项，删掉 “;“ ，加上 “alexanderzobnin-zabbix-datasource“

vim /etc/grafana/grafana.ini
[plugins]
..........
allow_loading_unsigned_plugins = alexanderzobnin-zabbix-datasource

#重启服务
systemctl  restart grafana-server

再次添加就行

Name自定义，Type选择Zabbix,Url填写访问zabbix-web的url（http://10.0.11.133/zabbix/api_jsonrpc.php），加上zabbix-api的php文件，Zabbix API details用户名密码需要在Zabbix-web页面中设置，也可以使用Zabbix的初始用户
