【滴滴开源运维监控系统】夜莺V5版本部署实践

滴滴开源运维监控系统-夜莺Nightingale

夜莺是新一代国产智能监控系统。对云原生场景、传统物理机虚拟机场景，都有很好的支持，10分钟完成搭建，1小时熟悉使用，经受了滴滴生产环境海量数据的验证，希望打造国产监控的标杆之作

新版Nightingale在2020.3.20发布v1版本，目前是v5.0版本，从这个版本开始，与Prometheus、VictoriaMetrics、Grafana、Telegraf等生态做了协同集成，力争打造国内最好用的开源运维监控系统。

systemctl start mysqld
netstat -anp | grep 3306
systemctl enable mysqld
查看初始密码
grep 'temporary password' /var/log/mysqld.log
修改密码
set password for root@localhost=password('MySQL_2022');
grant all privileges on *.* to root@'%' identified by 'MySQL_2022';
flush privileges;

二、安装prometheus

代码语言：javascript复制

mkdir -p /opt/prometheus
tar xf prometheus-2.33.1.linux-amd64.tar.gz
cp -far prometheus-2.33.1.linux-amd64/*  /opt/prometheus/
cd /opt/prometheus
chown -R root:root *

代码语言：javascript复制

# service 
cat <<EOF >/etc/systemd/system/prometheus.service
[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
EOF

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

代码语言：javascript复制

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install -y redis
systemctl enable redis
vim /etc/redis.conf

代码语言：javascript复制

systemctl restart redis

四、n9e部署

代码语言：javascript复制

mkdir /usr/local/n9e
tar -zxvf n9e-5.3.3.tar.gz -C /usr/local/n9e/

vim /usr/local/n9e/etc/server.conf 
配置文件中MySQL Redis连接密码修改以及对接IP地址修改
vim /usr/local/n9e/etc/webapi.conf 

mysql -uroot -p'MySQL_2022' < /usr/local/n9e/docker/initsql/a-n9e.sql
