prometheus安装

1. 首先去prometheus官网下载了安装包

　https://prometheus.io/download/

2. 上传安装包到服务器,然后解压 

解压之后的文件如上图所示

./prometheus --help   #查看命令

./prometheus  # 启动prometheus服务

3. 浏览器访问prometheus提供的UI界面 

    http://192.168.79.132:9090/graph

4. 将prometheus注册成系统服务(centos7)

cd /lib/systemd/system

创建文件prometheus.service

vim prometheus.service

在prometheus.service中添加如下内容:

[Unit]
Description=prometheus

[Service]
Restart=on-failure
ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml

然后加载配置

systemctl daemon-reload

测试promethues.service安装是否成功

systemctl status prometheus.service  # 查看服务状态
systemctl start prometheus.service  # 启动prometheus服务

至此prometheus服务安装算是完成!
