Centos7安装zabbix4.4.1和grafana7.1.1
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:

#通过msyql环境变量可以查看密码策略的相关信息

+----------------------------------------+-----------------+
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%'" mysql: [Warning] Using a password on the command line interface can be insecure. +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ #创建zabbix数据库及其用户 mysql -uroot -pPasswd123! -e "create database zabbix default character set utf8 collate utf8_bin" mysql -uroot -pPasswd123! -e "grant all on zabbix.* to 'zabbix'@'%' identified by 'zabbix'" #测试zabbix用户是否能够连接 [root@localhost ~]# mysql -uzabbix -pzabbix mysql: [Warning] Using a password on the command line interface can be insecure.

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

#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:3000
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://ip/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
#启动zabbix
systemctl enable --now zabbix-server
访问地址ip/zabbix
导入模板
可以通过访问 https://grafana.com/dashboards 来查看已有仪表盘模板，选取合适的使用
我这边已经导入了所以会有报错
应用导入的模板
安装mysql可能碰到的问题
