#更新yum源 yum makecache
1、安装prometheus-2.16.0
#prometheus官网 https://prometheus.io/download/ #通过wget下载prometheus wget https://github.com/prometheus/prometheus/releases/download/v2.16.0/prometheus-2.16.0.linux-amd64.tar.gz #同步时间 yum install -y ntpdate && ntpdate time.windows.com
#解压-安装 ll #解压至/usr/local/ tar -zxvf prometheus-2.16.0.linux-amd64.tar.gz -C /usr/local/ #将prometheus-2.16.0.linux-amd64改名为prometheus mv /usr/local/prometheus-2.16.0.linux-amd64/ /usr/local/prometheus cd /usr/local/prometheus ll #启动Prometheus—使用默认配置文件启动 /usr/local/prometheus/prometheus --config.file="/usr/local/prometheus/prometheus.yml" &
#查看9090端口是否开启 ss -anlt | grep 9090
#通过浏览器进入页面 IP:9090 #数据展示 IP:9090/metrics
说明有数据
2、安装grafana-7.2.0
Grafana是一款用Go语言开发的开源数据可视化工具，可以做数据监控和数据统计，带有告警功能，支持Graphite、elasticsearch、zabbix、InfluxDB、Prometheus和OpenTSDB作为数据源。Grafana主要特性：灵活丰富的图形化选项；可以混合多种风格；支持白天和夜间模式；多个数据源
#安装go语言环境 yum -y install go
#下载grafana-7.2.0-1.x86_64.rpm wget https://dl.grafana.com/oss/release/grafana-7.2.0-1.x86_64.rpm #安装 yum -y install grafana-7.2.0-1.x86_64.rpm
#开机自启grafana-server systemctl enable grafana-server #开启grafana-server systemctl start grafana-server #浏览器输入IP:3000 账号密码默认admin/admin 设置新密码
或docker安装Grafana
#yum安装docker yum -y install docker #或一键用docker安装grafana docker run -d --name=grafana -p 3000:3000 grafana/grafana-enterprise #分解步骤 # 在docker库中查找grafana镜像 docker search grafana # 从docker库拉取grafana镜像 docker pull grafana/grafana # 查看docker镜像 docker images #启动Grafana镜像 docker run -d -p 3000:3000 --name grafana grafana/grafana -d: deamon, 后台启动 -p: port, 端口映射，宿主机端口:容器内端口, 3000为grafana的web界面端口 --name grafana: 启动的程序名，此处为grafana grafana/grafana: 程序启动依赖的docker镜像 docker ps -a
3、安装mysql8.0数据库
#查看是否安装有数据库，避免mariadb和mysql数据库冲突 rpm -qa | grep -i mariadb rpm -qa | grep -i mysql yum -y remove mariadb-connector-c-3.0.6-7.oe1.x86_64 #查看可安装的mysql数据库 yum list mysql yum clean all yum makecache #安装数据库，启动数据库，并开机自启 yum -y install mysql mysql-libs mysql-devel mysql-server systemctl enable mysqld.service systemctl start mysqld.service #初始化 mariadb 并配置 root 密码 mysql_secure_installation #直接回车，空 是否设置密码：y 输入设置密码： 再次输入密码： 是否移除anonymous用户：y 是否不允许root远程登录：n 是否移除test数据库：y 是否更新：y
4、配置prometheus-2.16.0+grafana-7.2.0
/etc/hosts文件（添加路由），配置完路由后，服务器相互ping通即可 vi /etc/hosts
#Prometheus可以查看到监控的数据
#Grafana主界面配置prometheus数据源，服务器收集到的数据作为数据源添加到Grafana，这样Grafana就能把Prometheus的数据进行可视化。
#上传安装mysqld_exporter组件，改名 tar xf mysqld_exporter-0.11.0.linux-amd64.tar.gz -C /usr/local/ mv /usr/local/mysqld_exporter-0.11.0.linux-amd64/ /usr/local/mysqld_exporter ls /usr/local/mysqld_exporter #进入数据库，授权 mysql -u root -p mysql> grant select,replication client,process ON *.* to 'mysql_monitor'@'localhost' identified by '111111'; Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> quit 创建mysql配置文件 vi /usr/local/mysqld_exporter/.my.cnf [client] user=mysql_monitor password=111111 #启动mysqld_exporter nohup /usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf & #确认端口 ss -anlt | grep 9104
#添加Prometheus服务器配置，在最后添加如下内容（配置格式要注意，不然开启prometheus服务会报错） vi /usr/local/prometheus/prometheus.yml - job_name: mysqld static_configs: - targets: ['IP:9104']
#重启prometheus服务 pkill prometheus /usr/local/prometheus/prometheus --config.file="/usr/local/prometheus/prometheus.yml" &
#上传至/var/lib/grafana/ unzip grafana-dashboards-master.zip cp -R /var/lib/grafana/grafana-dashboards-master/dashboards/ /var/lib/grafana/
#更改grafana配置文件 vi /etc/grafana/grafana.ini [dashboards.json] enabled = true path = /var/lib/grafana/dashboards #重启Grafana服务 systemctl restart grafana-server
