Lepus天兔数据库监控系统(5.1)部署

一、介绍

Lepus是一套开源的数据库监控平台，目前已经支持MySQL、Oracle、PostgresQL、GreatSQL、MongoDB、Redis等数据库的基本监控和告警。Lepus无需在每台数据库服务器部署脚本或Agent，只需要在数据库创建授权帐号后，即可进行远程监控，适合监控数据库服务器较多的公司和监控云中数据库，这将为企业大大减化监控部署流程，同时Lepus系统内置了丰富的性能监控指标，让企业能够在数据库宕机前发现潜在性能问题进行处理，减少企业因为数据库问题导致的直接损失。

二、部署要求(基于Centos7.9搭建)

软件名称

推荐版本

必须

备注

Golang

1.4-1.8

否

源码编译运行必须安装/使用二进制方式无需安装

MySQL

5.6

是

用于存储基础数据和事件数据

InfluxDB

1.x

否

事件数据默认存储MySQL，支持存储到InfluxDB,如有使用InfluxDB需求则必须需要部署

Redis

5.x

是

用于报警系统限流

NSQ

1.2.x

是

基于gaolang的高性能消息队列，用于事件消息传输

三、部署mysql、redis、nsq

1、部署redis

1.下载reids
wget https://download.redis.io/releases/redis-6.2.6.tar.gz

2.解压并安装redis
tar xf redis-6.2.6.tar.gz -C /data/
cd redis-6.2.6
cd /data/redis-6.2.6/src/
make

启动redis

bind 0.0.0.0
protected-mode no
修改redis.conf这两个地方，然后启动
./redis-server /data/redis-6.2.6/redis.conf

2、部署NSQ

下载go，配置环境变量

wget https://studygolang.com/dl/golang/go1.18.3.linux-amd64.tar.gz
tar xvf go1.18.3.linux-amd64.tar.gz -C /usr/local/
vim /etc/profile
export PATH=$PATH:/usr/local/go/bin
export GOPATH=/data/gopath
source /etc/profile
go version

部署NSQ，并启动

wget https://s3.amazonaws.com/bitly-downloads/nsq/nsq-1.2.1.linux-amd64.go1.16.6.tar.gz
tar xvf nsq-1.2.1.linux-amd64.go1.16.6.tar.gz -C /data/
mkdir /data/nsqlog
cd /data/nsq-1.2.1.linux-amd64.go1.16.6/bin/
/data/nsq-1.2.1.linux-amd64.go1.16.6/bin/nsqd > /data/nsqlog/nsqd.log & 
#（守护进程；接收，缓存和投递消息给客户端）  如：nsqd -config=/home/nsq/bin/nsqd.cfg
/data/nsq-1.2.1.linux-amd64.go1.16.6/bin/nsqlookupd > /data/nsqlog/nsqlookupd.log &
#（守护进程；为消费者提供运行时发现服务，来查找指定话题（topic）的生产者 nsqd） 
/data/nsq-1.2.1.linux-amd64.go1.16.6/bin/nsqadmin --lookupd-http-address localhost:4160 > /data/nsqlog/nsqadmin.log &
#（提供 Web 页面用来实时的管理你的 NSQ 集群。它通过和 nsqlookupd 实例交流，来确定生产者）

3、部署mysql

脚本部署，需要开放外网，脚本和mysql安装包需要放到root目录执行

sh mysql_auto_install_5.7.sh 36
注：36是mysqlgilbc的版本号，其他版本号比如37版本就写37以此类推。


#!/bin/bash

#1.mysql官网下载二进制版本的mysql5.7.X安装包(mysql-5.7.X-linux-glibc2.12-x86_64.tar.gz)和mysql_auto_install.sh脚本放至/root目录
###### 二进制自动安装数据库脚本root默认密码为空, 将脚本和安装包放在/root目录即可.###############
######数据库目录/usr/local/mysql############
######数据目录/data/mysql############
######端口号默认3306其余参数按需自行修改############

四、下载二进制版本Lepus

进入官网下载页面，根据操作系统选择Linux或者Windows对应的二进制包，下载lepus二进制包，下载地址： Lepus数据库监控系统官方下载 – Lepus天兔开源企业级数据库监控系统 

Linux环境二进制包文件名为 ：lepus.5.x.linux-amd64.tar.gz Windows

环境二进制包文件名为：lepus.5.x.windows-amd64.zip

五、Linux环境二进制安装Lepus

1、安装包上传到/data目录，解压

2、进入lepus二进制目录，并导入数据库初始化表结构和数据

需要提前创建lepus库和账号授权
CREATE database lepus_db CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
create user 'lepus'@'%' identified by 'HkLjYQt4J8C%';
FLUSH PRIVILEGES;
grant all privileges on lepus_db.* to lepus@'%';
FLUSH PRIVILEGES;
cd /data/lepus.5.1.linux-amd64/sql/
mysql -uroot -p lepus_db < init_table.sql
mysql -uroot -p lepus_db < init_data.sql

3、修改配置文件

cd /data/lepus.5.1.linux-amd64/etc/
cp proxy.example.ini proxy.ini
cp alarm.example.ini alarm.ini
cp config.example.ini config.ini

proxy.ini

[main]
port = 8800
log = /tmp/lepus_proxy.log
debug=1
enable_influxdb=0

[nsq]
nsq_server = 127.0.0.1:4150

[mysql]
mysql_host = 127.0.0.1
mysql_port = 3306
mysql_user = lepus
mysql_password = HkLjYQt4J8C%
mysql_database = lepus_db

[influxdb]
influx_host = 127.0.0.1
influx_port = 8086
influx_user = lepus
influx_password =
influx_database = lepus_db

alarm.ini

[main]
debug=1
log = /tmp/lepus_alarm.log

[nsq]
nsq_server = 127.0.0.1:4150

[mysql]
mysql_host = 127.0.0.1
mysql_port = 3306
mysql_user = lepus
mysql_password = HkLjYQt4J8C%
mysql_database = lepus_db

[redis]
redis_host = 127.0.0.1
redis_port = 6379
redis_pass =

[mail]
mail_host = smtp.163.com
mail_port = 465
mail_user = [email protected]
mail_pass = password
mail_from = [email protected]

config.ini

[main]
log_dir = /tmp/
debug = 1
interval = 10
proxy = http://127.0.0.1:8800
db_pass_key = L1e2p3u4s5Abc321

[mysql]
mysql_host = 127.0.0.1
mysql_port = 3306
mysql_user = lepus
mysql_password = HkLjYQt4J8C%
mysql_database = lepus_db

4、启动服务组件

cd /data/lepus.5.1.linux-amd64/bin/
./lepus_proxy --config=../etc/proxy.ini &
./lepus_task --config=../etc/config.ini &
./lepus_alarm --config=../etc/alarm.ini &

启动后可以查看进程

查看运行日志，没有Error则运行正常

tail -f /tmp/lepus_proxy.log
tail -f /tmp/lepus_task.log
tail -f /tmp/lepus_alarm.log

六、二进制部署lepus-console

1、进入lepus-console-linux-amd64目录修改配置文件

tar xvf lepus-console.5.1.linux-amd64.tar.gz -C /data/
cd /data/lepus-console.5.1.linux-amd64/
cp setting.example.yml setting.yml

2、修改配置文件

setting.yml

log:
