首先准备环境。
由于prometheus是由go语言开发，所以需要先准备一个go语言环境。
下载地址：https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
再准备一个prometheus的tar包
下载地址：https://prometheus.io/download/
开始部署
1.首先将go的tar包解压至/usr/local目录下
[root@localhost ~]# tar -zxvf go1.8.3.linux-amd64.tar.gz -C /usr/local/
2.编辑环境变量配置文件，将export PATH=$PATH:/usr/local/go/bin加入至最后一行，然后source保存
[root@localhost ~]# vim /etc/profile
[root@localhost ~]# source /etc/profile
3.go version查看安装情况，出现结果说明安装成功
[root@localhost ~]# go version go version go1.8.3 linux/amd64
4.解压prometheus tar包至/usr/local目录下
[root@localhost ~]# tar -zxvf prometheus-2.27.1.linux-amd64.tar.gz -C /usr/local/
5.编辑prometheus.yml配置文件，写入以下文本，注意缩进
[root@localhost prometheus-2.27.1.linux-amd64]# vim prometheus.yml
[root@localhost prometheus-2.27.1.linux-amd64]# cat prometheus.yml
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: ‘prometheus‘
# metrics_path defaults to ‘/metrics‘
# scheme defaults to ‘http‘.
static_configs:
- targets: [‘localhost:9090‘]
- job_name: ‘db-1‘
static_configs:
- targets: [‘192.168.66.20:9104‘]
labels:
instance: ‘db-1‘
- job_name: ‘node-1‘
static_configs:
- targets: [‘192.168.66.20:9100‘]
labels:
instance: ‘node-1‘
#红色字体部分为加入配置
6.在被监控主机上安装go语言环境，安装exporter，tar包下载地址：https://prometheus.io/download/
安装步骤还是跟上边一样解压，需要注意的是监控mysql需要创建一个用户并授权，命令如下
mysql> GRANT REPLICATION CLIENT,PROCESS ON *.* TO ‘mysql_monitor‘@‘localhost‘ identified by ‘mysql_monitor‘; mysql> GRANT SELECT ON *.* TO ‘mysql_monitor‘@‘localhost‘;
7.随后在/usr/local/mysql_exporter目录下创建.my.cnf文件，将刚创建的用户名及密码写入，监控node则忽略这两步
[root@zabbix_server ~]# cat /usr/local/mysqld_exporter-0.13.0-rc.0.linux-amd64/.my.cnf [client] user=mysql_monitor password=mysql_monitor
8.prometheus主机开9090端口，mysql的默认监听端口是9104，node端口默认是9100，在被监控主机开启这两个端口，然后在两台主机启动
prometheus主机：
[root@localhost ~]# /usr/local/prometheus-2.27.1.linux-amd64/prometheus --config.file="/usr/local/prometheus-2.27.1.linux-amd64/prometheus.yml" &
被监控主机(mysql和node)：
[root@zabbix_server ~]# nohup /usr/local/node_exporter-1.1.2.linux-amd64/node_exporter & ##启动node
[root@zabbix_server ~]# nohup /usr/local/mysqld_exporter-0.13.0-rc.0.linux-amd64/mysqld_exporter --config.my-cnf="/usr/local/mysqld_exporter-0.13.0-rc.0.linux-amd64/.my.cnf" & ##启动mysql
9.浏览器访问prometheus主机ip:9090/targets
至此prometheus部署完成，接下来安装garfana进行可视化监控
10.下载并安装garfana
[root@zabbix_server ~]# wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.2.3-1.x86_64.rpm
[root@zabbix_server ~]# yum localinstall grafana-5.2.3-1.x86_64.rpm
11.加入系统服务并启动
[root@zabbix_server ~]# sudo /sbin/chkconfig --add grafana-server [root@zabbix_server ~]# sudo service grafana-server start Starting grafana-server (via systemctl): [ 确定 ]
12.防火墙开3000端口，浏览器访问,用户名密码默认admin/admin，第一次登陆会要求改密码
13.配置prometheus
14.完成
