    - Centos查看端口是否被占用：netstat -tunlp | grep 8086

    一、安装JDK

    1.查看JDK可安装版本
    yum search java|grep jdk

    [root@iZwz9ga2spyeb5u9tdq8t5Z /]# yum search java|grep jdk

    2.查安装JDK，这里安装的是open jdk，默认安装路径：/usr/lib/jvm/
    yum install -y java-1.8.0-openjdk-devel.x86_64

    3.配置JDK环境变量
    1）进入配置文件：vim /etc/profile
    2）在结尾处添加， G 快速移至最后一行：

    export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64
export CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

    3）重新加载profile文件：source /etc/profile
    4）验证JDK安装和配置成功：java -version

    二、安装JMeter

    1.官网下载到本地：http://jmeter.apache.org/download_jmeter.cgi

    Jmeter

    2.服务器创建安装目录

    [root@iZwz9ga2spyeb5u9tdq8t5Z local]   cd /usr/local
[root@iZwz9ga2spyeb5u9tdq8t5Z local]   mkdir jmeter

    3.上传并解压
    1）上传方式很多，自行百度。上传到jmeter目录下
    2）解压：unzip apache-jmeter-5.4.1.zip

    [root@iZwz9ga2spyeb5u9tdq8t5Z jmeter]# unzip apache-jmeter-5.4.1.zip 
[root@iZwz9ga2spyeb5u9tdq8t5Z jmeter]# ls
apache-jmeter-5.4.1  apache-jmeter-5.4.1.zip

    4.配置JMeter环境变量
    1）进入配置文件：vim /etc/profile
    2）在结尾处添加， G 快速移至最后一行：

    export JMETER_HOME=/usr/local/jmeter/apache-jmeter-5.4.1
export PATH=${JMETER_HOME}/bin:$PATH

    3）重新加载profile文件：source /etc/profile
    4）验证安装配置成功：jmeter -v

    [root@iZwz9ga2spyeb5u9tdq8t5Z jmeter]# jmeter -v
OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N

    二、安装InfluxDB

    1.指定目录下下载InfluxDB，由于之前安装2.x的兼容不了，这里学习记录的是1.x：
    - 1.0 wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.4.x86_64.rpm
    - 2.0 wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.0.4.x86_64.rpm
    2.安装InfluxDB：yum localinstall influxdb-1.8.4.x86_64.rpm，两个主要文件位置

    influxdb.service: /usr/lib/influxdb/scripts/influxdb.service
influxdb.conf: /etc/influxdb/influxdb.conf

    3.更改服务启动配置：vim influxdb.service
    1）将User和Group值改成root

    [Service]
User=root
Group=root
LimitNOFILE=65536
EnvironmentFile=-/etc/default/influxdb
ExecStart=/usr/bin/influxd -config /etc/influxdb/influxdb.conf $INFLUXD_OPTS
KillMode=control-group
Restart=on-failure

[Install]
WantedBy=multi-user.target
Alias=influxd.service

    2）重新生效服务：systemctl daemon-reload

    4.查看Influxdb安装成功：influx -version

    [root@iZwz9ga2spyeb5u9tdq8t5Z scripts]# influx -version
InfluxDB shell version: 1.8.4

    5.启动Influxdb服务
    1）临时启动：systemctl start influxdb
    2）开机启动：systemctl enable influxdb
    3）查看运行状态：ps -ef | grep -i "influx"或者service influxdb status

    [root@iZwz9ga2spyeb5u9tdq8t5Z /]# ps -ef | grep -i "influx"
influxdb 18955     1  0 19:21 ?        00:00:00 /usr/bin/influxd -config /etc/influxdb/influxdb.conf
root     22749 18221  0 19:24 pts/0    00:00:00 grep --color=auto -i influx

[root@iZwz9ga2spyeb5u9tdq8t5Z /]# service influxdb status
Redirecting to /bin/systemctl status influxdb.service
● influxdb.service - InfluxDB is an open-source, distributed, time series database
   Loaded: loaded (/usr/lib/systemd/system/influxdb.service; enabled; vendor preset: disabled)
   Active: active (running) since 一 2021-05-03 19:21:06 CST; 4min 22s ago
     Docs: https://docs.influxdata.com/influxdb/
 Main PID: 18955 (influxd)
   CGroup: /system.slice/influxdb.service
           └─18955 /usr/bin/influxd -config /etc/influxdb/influxdb.conf

    6.创建Influxdb数据库
    1） 进入influx命令：influx

    [root@iZwz9ga2spyeb5u9tdq8t5Z /]# influx
Connected to http://localhost:8086 version 1.8.4
InfluxDB shell version: 1.8.4

    2）展示数据库，和mysql类似：show databases

    > show databases
name: databases
name
----
_internal

    3）创建/删除数据库： create/drop(删除) jmeter(库名)

    > create database jmeter
> show databases
name: databases
name
----
_internal
jmeter

    4）切换数据库：use jmeter(库名)；展示表：show measurements

    > use jmeter
Using database jmeter
> show measurements
>

    5）创建measurements：influxdb中没有创建表的语句，是直接通过insert语句实现measurement
    insert语法：insert measurementName,tag1=value1[,tag2=value2] field1=value1[,field2=value2] <时间戳>

    • insert
    > insert aliyun,name="lily",age=18 favourite="melon",job=800
> insert aliyun,name="harry",age=22 favourite="magic",job=666
> show measurements
name: measurements
name
----
aliyun
>
    • 查询该表aliyun
    > select * from aliyun
name: aliyun
time                age favourite job name
----                --- --------- --- ----
1620047056397676385 18  melon     800 "lily"
1620047100232010422 22  magic     666 "harry"
>

    ※会发现查询出来的时间是时间戳，解决办法是：influx -precision rfc3339启动数据库

    • 查询所有tag的key和value：age name 
    keys：
> show tag keys from aliyun
name: aliyun
tagKey
------
age
name
> 

values：
> show tag values from aliyun with key="name"
name: aliyun
key  value
---  -----
name "harry"
name "lily"
>
    • ※疑问：
      a） 如何修改端口？2.x怎么安装？小二还没摸索明白~~
      b）官网说的yum安装，还有密钥认证，小二也没成功

    三、安装Chronograf

    由于InfluxDB1.x以后就没有了webUI界面，所以需要Chronograf来实现可视化构建

    1.下载安装Chronograf
    wget https://dl.influxdata.com/chronograf/releases/chronograf-1.8.10.x86_64.rpm
    sudo yum localinstall chronograf-1.8.10.x86_64.rpm

    2.启动Chronograf：systemctl start chronograf，同样可以设置开机启动
    3.访问webUI界面，配置influxdb数据库：http://ip:8888
    一路点到底，因为小二也不知道那些字段干什么的？/(ㄒoㄒ)/~~

    新增数据库连接 配置数据库

    四、安装Grafana

    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:https://grafana.com/grafana/download

    1.切换到指定目录下rpm方式下载
    wget https://dl.grafana.com/oss/release/grafana-7.4.3-1.x86_64.rpm

    2.安装：sudo yum install grafana-7.4.3-1.x86_64.rpm，配置文件grafana.ini位置

    [root@iZwz9ga2spyeb5u9tdq8t5Z grafana]# ls
grafana.ini  ldap.toml  provisioning
[root@iZwz9ga2spyeb5u9tdq8t5Z grafana]# pwd
/etc/grafana

    3.启动grafana
    1）开机启动
    启动服务：systemctl start grafana-server
    开机启动：systemctl enable grafana-server
    重新启动：systemctl restart grafana-server

    2）查看启动状态

    [root@iZwz9ga2spyeb5u9tdq8t5Z grafana]# service grafana-server status
● grafana-server.service - Grafana instance
   Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2021-05-05 17:56:30 CST; 1min 56s ago
     Docs: http://docs.grafana.org
 Main PID: 18383 (grafana-server)
   CGroup: /system.slice/grafana-server.service

    4.配置grafana：默认监听端口3000，账号admin/admin
    1）添加数据源
    Configration –>Data Sources –> Add data source 选择InfluxDB

    配置InfluxDB image.png

    点击 Save&Test 后出现绿色提示代表添加成功

    保存

    2）寻找仪表盘Dashboard模板：https://grafana.com/dashboards?dataSource=influxdb

    输入jmeter 复制ID

    3）添加仪表盘Dashboard：Create→Import

    第一步Import 第二步Load 第三步确认

    ※这里的measurement name要和jmeter里的一致~

    五、安装Prometheus

    1.官网下载：https://prometheus.io/docs/introduction/first_steps/，以二进制方式安装

    下载地址

    2.安装Prometheus和node_exporter

    • 创建目录：mkdir prometheus
    • 上传压缩包
    • 解压文件：tar -zxvf prometheus.tar.gz
    • 修改解压文件夹名称：mv prometheus-2.26.0.linux-amd64 prometheus
    • 进入prometheus目录下：cd prometheus

    3.启动服务：./prometheus --config.file=prometheus.yml &

    level=info ts=2021-05-11T05:39:39.559Z caller=main.go:815 fs_type=EXT4_SUPER_MAGIC
level=info ts=2021-05-11T05:39:39.559Z caller=main.go:818 msg="TSDB started"
level=info ts=2021-05-11T05:39:39.559Z caller=main.go:944 msg="Loading configuration file" filename=prometheus.yml
level=info ts=2021-05-11T05:39:39.560Z caller=main.go:975 msg="Completed loading of configuration file" filename=prometheus.yml totalDuration=906.425µs remote_storage=7.891µs web_handler=543ns query_engine=1.073µs scrape=346.046µs scrape_sd=81.428µs notify=54.125µs notify_sd=30.896µs rules=4.826µs
level=info ts=2021-05-11T05:39:39.560Z caller=main.go:767 msg="Server is ready to receive web requests."

    4.版本查询：./promethues --version

    [root@iZwz9ga2spyeb5u9tdq8t5Z prometheus]  ./prometheus --version
prometheus, version 2.26.0 (branch: HEAD, revision: 3cafc58827d1ebd1a67749f88be4218f0bab3d8d)
  build user:       root@a67cafebe6d0
  build date:       20210331-11:56:23
  go version:       go1.16.2
  platform:         linux/amd64

    4.访问UI界面：IP:9090

    • 打开网页输入以下指令
      rate(promhttp_metric_handler_requests_total{code="200"}[1m])
      输入指令

    5.下载安装node_exporter：https://prometheus.io/download/

    下载地址
    • 创建文件夹：mkdir /etc/default/node_exporter
    • 上传压缩文件
    • 解压文件：tar -zxvf node_exporter.1.1.2.linux-amd64.tar.gz
    • 修改解压文件夹名称：mv node_exporter.1.1.2.linux-amd64 node_exporter
    • 进入目录：cd node_exporter
    • 启动服务：nohup /etc/default/node_exporter/node_exporter/node_exporter &
    • 打开UI：IP:9100，查看端口：lsof -i:9100 
    [root@iZwz9ga2spyeb5u9tdq8t5Z node_exporter]# lsof -i:9100
COMMAND     PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
node_expo 30994 root    3u  IPv6 4015988      0t0  TCP *:jetdirect (LISTEN)
    Node_exporter

    6.编辑Prometheus配置文件:

    • 先杀掉prometheus：pkill prometheus 
    level=info ts=2021-05-11T05:22:10.102Z caller=main.go:668 msg="Stopping scrape discovery manager..."
level=info ts=2021-05-11T05:22:10.102Z caller=main.go:682 msg="Stopping notify discovery manager..."
level=info ts=2021-05-11T05:22:10.102Z caller=main.go:704 msg="Stopping scrape manager..."
level=info ts=2021-05-11T05:22:10.102Z caller=main.go:664 msg="Scrape discovery manager stopped"
level=info ts=2021-05-11T05:22:10.102Z caller=main.go:678 msg="Notify discovery manager stopped"
level=info ts=2021-05-11T05:22:10.102Z caller=manager.go:934 component="rule manager" msg="Stopping rule manager..."
level=info ts=2021-05-11T05:22:10.102Z caller=manager.go:944 component="rule manager" msg="Rule manager stopped"
level=info ts=2021-05-11T05:22:10.103Z caller=main.go:698 msg="Scrape manager stopped"
level=info ts=2021-05-11T05:22:10.110Z caller=notifier.go:601 component=notifier msg="Stopping notification manager..."
level=info ts=2021-05-11T05:22:10.110Z caller=main.go:872 msg="Notifier manager stopped"
level=info ts=2021-05-11T05:22:10.111Z caller=main.go:884 msg="See you next time!"
    • 然后vim prometheus.yml，在最后面添加：
    [root@iZwz9ga2spyeb5u9tdq8t5Z prometheus]# vim prometheus.yml 
# Here it's Prometheus itself.
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: 'xxx.xx.xxx.xxx'
    static_config:
    - targets: ['xxx.xx.xxx.xx:9100']

    参考：https://blog.csdn.net/qq_43417559/article/details/109012296

    7.重启服务：./prometheus --config.file=prometheus.yml &
    8.访问IP:9090，点击导航栏中的status→targets。显示如下图说明配置成功
    ※如果状态位DOWN，需要检查下防火墙是否关闭

    配置结果

    9.在Grafana中配置prometheus

    • 添加prometheus的data sources
    • Import Dashboard，方法跟Influxdb类似，不做过多介绍

    10.Jmeter非GUI命令运行
    jmeter -n -t file.jmx -l result.jtl -e -o reopot

    • -n：非GUI模式运行
    • -t：指定jmx文件位置
    • -l：指定生成jtl的格式结果
    • -e：生成html报告
    • -o：指定html报告文件夹（必须是空目录）
