prometheus + influxdb + grafana + mysql

前言

本文介紹使用influxdb 做爲prometheus持久化存儲和使用mysql 做爲grafana 持久化存儲的安裝方法

一 安裝go環境

若是本身有go環境能夠自主編譯remote_storage_adapter插件，安裝go環境目的就是爲了得到此插件，若是沒有go環境能夠使用我分享的鏈接下載。

連接: https://pan.baidu.com/s/1DJpoYDOIfCeAFC6UGY22Xg 提取碼: uj42

1 下載  

wget https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz

2 安裝

tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz 添加環境變量 vim /etc/profile export GOROOT=/usr/local/go export GOBIN=$GOROOT/bin export GOPKG=$GOROOT/pkg/tool/linux_amd64 export GOARCH=amd64 export GOOS=linux export GOPATH=/go export PATH=$PATH:$GOBIN:$GOPKG:$GOPATH/bin vim /etc/profile go get -d -v 

二  安裝  influxdb  

1 下載並安裝

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.5.2.x86_64.rpm sudo yum localinstall influxdb-1.5.2.x86_64.rpm

2 啓動influxdb  

systemctl start influxdb systemctl enable influxdb 以非服務方式啓動 influxd 須要指定配置文件的話，能夠使用 --config 選項，具體能夠help下看看

3 查看相關配置

安裝後， 在/usr/bin下面有以下文件

influxd influxdb服務器 influx influxdb命令行客戶端 influx_inspect 查看工具 influx_stress 壓力測試工具 influx_tsm 數據庫轉換工具（將數據庫從b1或bz1格式轉換爲tsm1格式） 

在 /var/lib/influxdb/下面會有以下文件夾

data 存放最終存儲的數據，文件以.tsm結尾 meta 存放數據庫元數據 wal 存放預寫日誌文件

配置文件路徑 ：/etc/influxdb/influxdb.conf

4 建立http接口用於普羅米修斯

如何進入到db中

influx

如何建立一個prometheus庫http 接口

curl -XPOST http://localhost:8086/query --data-urlencode "q=CREATE DATABASE prometheus" 

三 安裝prometheus

1 下載 

https://prometheus.io/download/

2 解壓安裝

tar xf prometheus-2.8.0.linux-amd64.tar.gz

mv prometheus-2.8.0.linux-amd64 /usr/local/prometheus cd /usr/local/prometheus ./prometheus --version

四 準備remote_storage_adapter

在github上準備一個 remote_storage_adapter 的可執行文件，而後啓動它，若是想獲取相應的幫助能夠使用:./remote_storage_adapter -h來獲取相應幫助(修改綁定的端口，influxdb的設置等..)，如今咱們啓動一個remote_storage_adapter來對接influxdb和prometheus：
./remote_storage_adapter -influxdb-url=http://localhost:8086/ -influxdb.database=prometheus -influxdb.retention-policy=autogen，influxdb默認綁定的端口爲9201

1 build 插件

/usr/local/go/bin/go get github.com/prometheus/documentation/examples/remote_storage/remote_storage_adapter/

2 使用插件

./remote_storage_adapter --influxdb-url=http://127.0.0.1:8086/ --influxdb.database="prometheus" --influxdb.retention-policy=autogen

3 修改prometheus文件

vim prometheus.yml 
添加：
 #Remote write configuration (for Graphite, OpenTSDB, or InfluxDB). remote_write: - url: "http://localhost:9201/write"  # Remote read configuration (for InfluxDB only at the moment). remote_read: - url: "http://localhost:9201/read" 

4 啓動 prometheus

./prometheus

5 查看有無數據上報

此時只監控了server自己

6 查看 influxdb 數據庫內容

7 向添加一個node節點

下載
wget https://github.com/prometheus/node_exporter/releases/download/v0.17.0/node_exporter-0.17.0.linux-amd64.tar.gz 安裝agent tar xf node_exporter-0.17.0.linux-amd64.tar.gz cd node_exporter-0.17.0.linux-amd64 ./node_exporter 向prometheus 註冊節點 vim prometheus.yml scrape_configs下添加 - job_name: 'linux-node' static_configs: - targets: ['10.10.25.149:9100'] labels: instance: node1 重啓 prometheus 

8 將prometheus寫成系統服務

cat>/lib/systemd/system/prometheus.service<<EOF
[Service]
Restart=on-failure
WorkingDirectory=/usr/local/prometheus/
ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml
[Install]
WantedBy=multi-user.target
EOF


chown 644 /lib/systemd/system/prometheus.service
systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus
systemctl status prometheus

9 將agent寫成系統服務

cat>/lib/systemd/system/node_exporter.service<<EOF
[Service]
Restart=on-failure
WorkingDirectory=/root/node_exporter-0.17.0.linux-amd64
ExecStart=/root/node_exporter-0.17.0.linux-amd64/node_exporter
[Install]
WantedBy=multi-user.target
EOF


chown 644 /lib/systemd/system/node_exporter.service
systemctl daemon-reload
systemctl enable node_exporter
systemctl start node_exporter
systemctl status node_exporter

10 將remote_storage_adapter註冊爲系統服務

cat>/lib/systemd/system/remote_storage_adapter.service<<EOF
[Service]
Restart=on-failure
WorkingDirectory=/root/
ExecStart=/root/remote_storage_adapter --influxdb-url=http://127.0.0.1:8086/ --influxdb.database="prometheus" --influxdb.retention-policy=autogen [Install] WantedBy=multi-user.target EOF chown 644 /lib/systemd/system/remote_storage_adapter.service systemctl daemon-reload systemctl enable remote_storage_adapter systemctl start remote_storage_adapter systemctl status remote_storage_adapter

五 安裝 grafana

1 下載 

wget https://dl.grafana.com/oss/release/grafana-6.0.2-1.x86_64.rpm

2 安裝

yum install grafana-6.0.2-1.x86_64.rpm systemctl start grafana-server systemctl enable grafana-server grafana-server -v grafana-server 監聽端口爲 3000

3 訪問 grafana-server 

http://ServerIP:3000 默認用戶名密碼爲： admin admin

六 安裝 mysql

1 添加源

rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm yum repolist enabled | grep "mysql.*-community.*"

2 安裝 mysql-5.6

yum -y install mysql-community-server

3 啓動mysql並簡單安全設置

systemctl enable mysqld
systemctl start mysqld systemctl status mysqld mysql_secure_installation 設置密碼一路Y 

4 建立grafana 數據庫

create database grafana; create user grafana@'%' IDENTIFIED by 'grafana'; grant all on grafana.* to grafana@'%'; flush privileges;

七 修改grafana默認數據庫並配置grafana

1 修改配置文件鏈接mysql

vim /etc/grafana/grafana.ini

[database]
type = mysql
host = 127.0.0.1:3306
name = grafana
user = grafana
password =grafana
url = mysql://grafana:grafana@localhost:3306/grafana

[session]
provider = mysql
provider_config = `grafana:grafana@tcp(127.0.0.1:3306)/grafana`

2 重啓grafana

systemctl restart grafana-server 

3 訪問grafana

http://serverip:3000

4 查看數據庫

mysql> show databases;
+--------------------+
| Database | +--------------------+ | information_schema | | grafana | | mysql | | performance_schema | +--------------------+ mysql> use grafana Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +--------------------------+ | Tables_in_grafana | +--------------------------+ | alert | | alert_notification | | alert_notification_state | | annotation | | annotation_tag | | api_key | | dashboard | | dashboard_acl | | dashboard_provisioning | | dashboard_snapshot | | dashboard_tag | | dashboard_version | | data_source | | login_attempt | | migration_log | | org | | org_user | | playlist | | playlist_item | | plugin_setting | | preferences | | quota | | server_lock | | session | | star | | tag | | team | | team_member | | temp_user | | test_data | | user | | user_auth | | user_auth_token | +--------------------------+ 33 rows in set (0.00 sec) 

5 配置 grafana 添加數據源

因爲使用influxDB做爲prometheus的持久化存儲，因此添加的influxDB數據源，因爲influxDB未設置密碼因此此處沒有填寫密碼
