选择最新版amd64（网速差，可以先下载到本地，再上传到服务器）
wget https://github.com/prometheus/prometheus/releases/tag/v2.35.0/prometheus-2.35.0.linux-amd64.tar.gz --no-check-certificate
解压修改配置文件，默认localhost替换为具体地址

参数说明：
nohup “xxxx” & ：后端启动prometheus ：执行命令文件–config.file ：指定配置文件–web.enable-lifecycle：支持通过http请求重载配置（热加载）🥈登录验证prometheus.log 2>&1：>-覆盖写入日志、prometheus.log-日志名称、2>&1-写入全部日志，不管对错
查看日志，对应监听端口为9090

默认情况下prometheus会将采集的数据存放到本地磁盘data下面（二进制文件），为了方便查看和扩展，接下来使用influxdb来存储数据。
创建部署用户，赋予sudo权限
[root@host1 ~]# useradd influx
[root@host1 ~]# passwd influx
更改用户 influx 的密码 。
新的 密码：
无效的密码： 密码少于 8 个字符
重新输入新的 密码：

🥉初始化用户信息，全都是必填项
添加如下配置
# set db
remote_write:
- url: "http://192.168.56.10:8086/api/v1/prom/write?db=prometheus&u=prometheus&p=prometheus"
remote_read:
- url: "http://192.168.56.10:8086/api/v1/prom/read?db=prometheus&u=prometheus&p=prometheus"
直接刷新页面没反应，需执行如下命令
curl -X POST http://192.168.56.10:9090/-/reload
直接在prometheus用户下面建立exporter目录

配置java变量
[prometheus@host1 flume]$ cd conf/

[prometheus@host1 conf]$ cp flume-env.sh.template flume-env.sh
[prometheus@host1 conf]$ cp flume-conf.properties.template flume-conf.properties
[prometheus@host1 conf]$ vi flume-env.sh
定义相关参数
[prometheus@host1 conf]$ vi flume-conf.properties
[prometheus@host1 conf]$ cat flume-conf.properties
#Agent: 名称定义为 a1
#Source:可以理解为输入端，定义名称为 r1
#channel：传输频道，定义为 c1，设置为内存模式
#sinks：可以理解为输出端，定义为 s1
＃命名此代理上的组件别名
a1.sources = r1
a1.channels = c1
a1.sinks = s1
＃描述配置源
a1.sources.r1.type = netcat
a1.sources.r1.bind = 192.168.56.10

＃描述接收器
#设置 Sink 为 logger 模式

#设置 channel 信息
a1.channels.c1.type = memory
#内存模式
a1.channels.c1.capacity = 1000
#通道中最大的缓冲事件,要大于或等于batchSize的数
a1.channels.c1.transactionCapacity = 100
＃将源和接收器绑定到通道

监控目标
数据并未写入influxdb,看页面，还需要创建telegraf,而且上面配置的api应该也不对，里面有v1,实际上安装的是v2
下载
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.22.3_linux_amd64.tar.gz
登录influxdb,拷贝前面定义的telegrafs的内容，添加到telegraf.conf配置文件，同时配置环境变量
export INFLUX_TOKEN=-jExfGZAinmMYdY98xQLuKK3xtuJdjvFasLBq_X8wb_gtnkgdHozcb0ph-gW-8C8xFtx3JFIM7irEwKe2kjkxw==

paths = ["/receive"]
data_format = "influx"
[influx@host1 telegraf]$
启动telegraf
nohup /home/influx/telegraf-1.22.3/usr/bin/telegraf --config /home/influx/telegraf-1.22.3/etc/telegraf/telegraf.conf &
修改为remote_write
remote_write:
- url: "http://192.168.56.10:8087/receive"
重新加载
[prometheus@host1 prometheus]$ curl -X POST http://192.168.56.10:9090/-/reload
注意：[[inputs.prometheus]]对应下面targets,配置几个采集几个！！！

看2.0API官网说明不用好像也行，问题是不知道prometheus该怎么配。Java开发、curl模拟都ok
