Nightingale夜莺监控部署安装和使用

1.0 背景介绍

最近在对开源的新型监控做调研，发现Nightingale功能强大，使用效果还不错,并对，并对目前监控做了一个对比

夜莺监控（ Nightingale ）是一款国产、开源云原生监控分析系统，采用 All-In-One 的设计，集数据采集、可视化、监控告警、数据分析于一体。于 2020 年 3 月 20 日，在 github 上发布 v1 版本，已累计迭代 60 多个版本。从 v5 版本开始与 Prometheus、VictoriaMetrics、Grafana、Telegraf、Datadog 等生态紧密协同集成，提供开箱即用的企业级监控分析和告警能力，已有众多企业选择将 Prometheus + AlertManager + Grafana 的组合方案升级为使用夜莺监控。

2.0 安装部署

2.1 安装依赖组件

# 安装 mysql 数据库
yum -y install mariadb*
systemctl enable mariadb
systemctl restart mariadb
systemctl status mariadb


mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('1234');"


# 安装 redis
yum install -y redis
systemctl enable redis
systemctl restart redis
systemctl status redis

2.2安装prometheus,并配置服务启动参数

prometheus官网下载
https://prometheus.io/download/


下载不下来用下面的
链接：https://pan.baidu.com/s/1KSwB0YTWYvnTGH_98dfC6g 
提取码：4xpo

mkdir -p /opt/prometheus
wget https://github.com/prometheus/prometheus/releases/download/v2.28.0/prometheus-2.28.0.linux-amd64.tar.gz -O prometheus-2.28.0.linux-amd64.tar.gz
或者
wget https://s3-gz01.didistatic.com/n9e-pub/prome/prometheus-2.28.0.linux-amd64.tar.gz -O prometheus-2.28.0.linux-amd64.tar.gz
下载不下来 用上面的网盘下载 后 
上传至服务器后解压缩


tar xf prometheus-2.28.0.linux-amd64.tar.gz
cp -far prometheus-2.28.0.linux-amd64/*  /opt/prometheus/

2.3prometheus服务设置

vim /etc/systemd/system/prometheus.service
如下


[Unit]
Description="prometheus"
Documentation=https://prometheus.io/
After=network.target


[Service]
Type=simple


ExecStart=/opt/prometheus/prometheus  --config.file=/opt/prometheus/prometheus.yml --storage.tsdb.path=/opt/prometheus/data --web.enable-lifecycle --enable-feature=remote-write-receiver --query.lookback-delta=2m 


Restart=on-failure
SuccessExitStatus=0
LimitNOFILE=65536
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=prometheus




[Install]
WantedBy=multi-user.target

2.4prometheus开启服务及开机启动设置

systemctl daemon-reload
systemctl enable prometheus
systemctl restart prometheus
systemctl status prometheus

3.0安装夜莺并配置启动（二进制方式）

mkdir -p /opt/n9e && cd /opt/n9e


# 去 https://github.com/didi/nightingale/releases 
我下载的n9e-v6.6.1-linux-amd64.tar.gz


 tar zxvf n9e-v6.6.1-linux-amd64.tar.gz 


mysql -uroot -p1234 < docker/initsql/a-n9e.sql


cd /opt/n9e
nohup ./n9e server &> server.log &
nohup ./n9e webapi &> webapi.log &
查看进程
ps -ef | grep n9e server
ps -ef | grep n9e webapi

配置启动

vim /opt/n9e/etc/config.toml

下面更改mysql的信息的真实地址 更改为你的信息 我的是本机部署 不改动 root密码1234 和上面一样 我也不改


[DB]
# postgres: host=%s port=%s user=%s dbname=%s password=%s sslmode=%s
# postgres: DSN="host=127.0.0.1 port=5432 user=root dbname=n9e_v6 password=1234 sslmode=disable"
DSN="root:1234@tcp(127.0.0.1:3306)/n9e_v6?charset=utf8mb4&parseTime=True&loc=Local&allowNativePasswords=true"
# enable debug mode or not
Debug = false
# mysql postgres
DBType = "mysql"
# unit: s

更改redis的地址的真实地址  我是本机部署   我不需要需要更改


[Redis]
# address, ip:port or ip1:port,ip2:port for cluster and sentinel(SentinelAddrs)
Address = "127.0.0.1:6379"
# Username = ""
# Password = ""
# DB = 0
# UseTLS = false
# TLSMinVersion = "1.2"
# standalone cluster sentinel
RedisType = "standalone"
# Mastername for sentinel type
# MasterName = "mymaster"
# SentinelUsername = ""
# SentinelPassword = ""

更改prometheus的真实地址 我是本机部署 不更改


[[Pushgw.Writers]]
# Url = "http://127.0.0.1:8480/insert/0/prometheus/api/v1/write"
Url = "http://127.0.0.1:9090/api/v1/write"
# Basic auth username
BasicAuthUser = ""
# Basic auth password
BasicAuthPass = ""
# timeout settings, unit: ms
Headers = ["X-From", "n9e"]
Timeout = 10000
DialTimeout = 3000
TLSHandshakeTimeout = 30000
ExpectContinueTimeout = 1000
IdleConnTimeout = 90000

其他配置保持默认即可,如果启动成功，server 默认会监听在 19000 端口，webapi 会监听在 18000 端口默认用户是root，密码是root.2020

http://10.10.201.222:17000/
netstat  -tlnp | grep 17000

3.2配置采集器categraf

github地址

https://github.com/flashcatcloud/categraf/releases/tag/v0.2.35

下载二进制包

wge  https://github.com/flashcatcloud/categraf/releases/download/v0.2.35/categraf-v0.2.35-linux-amd64.tar.gz


tar zxvf categraf-0.2.35.tar.gz
mv categraf-0.2.35 categraf
vim /opt/n9e/categraf/conf/config.toml

我这里配置的是本机所以是127.0.0.1/其他机器请配置真实ip

[[writers]]
url = "http://127.0.0.1:17000/prometheus/v1/write"

[heartbeat]
enable = true


# report os version cpu.util mem.util metadata
url = "http://127.0.0.1:17000/v1/n9e/heartbeat"

配置systemd 启动管理

vim /etc/systemd/system/categraf.service
如下




[Unit]
Description="Categraf"
After=network.target


[Service]
Type=simple


ExecStart=/opt/n9e/categraf/categraf
WorkingDirectory=/opt/n9e/categraf/


Restart=on-failure
SuccessExitStatus=0
LimitNOFILE=65536
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=categraf




[Install]
WantedBy=multi-user.target

systemctl daemon-reload
systemctl enable categraf
systemctl enable categraf
systemctl restart categraf
systemctl status categraf
