Grafana安装
上传Grafana安装包或者下载rpm安装包到服务器,执行如下命令安装:
配置yum源
[root@localhost ~]# vim /etc/yum.repos.d/grafana.repo
[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm-beta
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packages.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
[root@localhost ~]# yum -y install grafana
启动grafana-server
systemctl start grafana-server
systemctl status grafana-server
systemctl enable grafana-server.service
定义环境变量文件:/etc/sysconfig/grafana-server
/etc/sysconfig/grafana-server文件内容:不用修改
配置文件:/etc/grafana/grafana.ini 不用修改
Paths配置段
#################################### Paths ####################################
[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
;data = /var/lib/grafana # 默认存放数据位置
# Temporary files in `data` directory older than given duration will be removed
;temp_data_lifetime = 24h
# 删除 'data'目录给定时间前的临时文件,使用0则不删除临时文件,时间格式h,m。如168h,30m,10h30m
# Directory where grafana can store logs
;logs = /var/log/grafana # grafana存储日志的目录
# Directory where grafana will automatically scan and look for plugins
;plugins = /var/lib/grafana/plugins # grafana存放插件的目录
# folder that contains provisioning config files that grafana will apply on startup and while running.
;provisioning = conf/provisioning
Server配置段
[server]
# Protocol (http, https, h2, socket)
;protocol = http #支持的协议
# The ip address to bind to, empty will bind to all interfaces
;http_addr = #服务监听的地址
# The http port to use
;http_port = 3000 #监听的端口
# The public facing domain name used to access grafana from a browser
;domain = localhost #使用域名访问服务
# Redirect to correct domain if host header does not match domain
# Prevents DNS rebinding attacks
;enforce_domain = false #是否 强制使用域名访问服务
# The full public facing url you use in browser, used for redirects and emails
# If you use reverse proxy and sub path specify full url (with sub path)
;root_url = %(protocol)s://%(domain)s:%(http_port)s/ #定义访问服务的路径
# Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons.
;serve_from_sub_path = false
# Log web requests #是否记录web请求
;router_logging = false
# the path relative working path #定义静态文件的访问路径
;static_root_path = public
# enable gzip #是否开启压缩
;enable_gzip = false
# https certs & key file #证书文件
;cert_file =
;cert_key =
# Unix socket path #定义socket路径
;socket =
grafana默认存储数据采用的是sqlite3数据库,当然我们也可以使用mysql,这个需要在grafana配置文件中更改Database相关的配置即可
grafana的UI管理页面默认监听端口是3000,也可以通过修改配置文件server的相关配置即可
grafana默认登录的管理员账号密码都是:admin
改变默认登录 密码!,然后进入系统
安装zabbix 插件点击如图所示
复制图中代码在xshell中执行命令
grafana-cli plugins install alexanderzobnin-zabbix-app
这表示zabbix插件安装成功
重启grafana
systemctl restart grafana-server.service
回到主页,开启zabbix app
再次添加zabbix作为数据源zabbix的用户名:admin
zabbix的密码:zabbix
这里会有添加的三个仪表盘
创建一个仪表盘
可以看到效果
注意:务必要保证zabbix-server 和grafana server 这两台服务器的时间保持同步,否则 grafana server 是不会出图的!
时间同步
[root@localhost ~]# yum -y install ntpdate
[root@localhost ~]# ntpdate 2.cn.pool.ntp.org
