小米系统基础架构（搭建小米的监控系统）

一、环境准备1、配置防火墙，今天小编就来说说关于小米系统基础架构?下面更多详细答案一起来看看吧!

小米系统基础架构

open-falcon的目标是做最开放、最好用的互联网企业级监控产品。

一、环境准备

1、配置防火墙

开放端口6030、8433、8081，允许任意IP访问

firewall-cmd --add-port=6030/tcp --permanent firewall-cmd --add-port=8433/tcp --permanent firewall-cmd --add-port=8081/tcp --permanent firewall-cmd --reload

2、安装wget、vim、git

yum install -y wget vim git

3、安装golang、redis

yum install -y epel-release yum install -y golang yum install -y redis #启动开机启动redis systemctl start redis systemctl enable redis

4、安装mysql 5.6

#获取repo wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm #安装rpm包 rpm -ivh mysql-community-release-el7-5.noarch.rpm #安装MySQL yum install -y mysql-server #启动Mysql systemctl start mysql

5、设置临时位置变量

export GOROOT=/usr/lib/golang export GOPATH=/opt/git

6、在github下载后端

# 创建存放源码文件的目录 mkdir -p $GOPATH/src/github.com/open-falcon cd $GOPATH/src/github.com/open-falcon #克隆源码 git clone http://github.com/open-falcon/falcon-plus.git

7、初始化数据库

cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema # 执行5个脚本初始化数据库，提示“Enter password”，如果mysql的root没有设置密码，回车即可 mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql

8、编译后端源码

cd $GOPATH/src/github.com/open-falcon/falcon-plus #编译 make all #打包 make pack

二、部署后端

1、设置临时位置变量

export backSPACE=/opt/open-falcon/back

2、创建工作目录

mkdir -p $BACKSPACE

3、解压缩包

cd $GOPATH/src/github.com/open-falcon/falcon-plus tar -xzvf open-falcon-v0.2.1.tar.gz -C $BACKSPACE

4、修改各模块配置文件cfg.json

①、vim /opt/open-falcon/back/aggregator/config/cfg.json "database": { "addr": "root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true", "idle": 10, "ids": [1, -1], "interval": 55 ②、vim /opt/open-falcon/back/graph/config/cfg.json "db": { "dsn": "root:passwd@tcp(127.0.0.1:3306)/graph?loc=Local&parseTime=true", "maxIdle": 4 }, ③、vim /opt/open-falcon/back/hbs/config/cfg.json { "debug": true, "database": "root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true", "hosts": "", "maxConns": 20, "maxIdle": 15, "listen": ":6030", "trustable": [""], "http": { "enabled": true, "listen": "0.0.0.0:6031" } } ④、vim /opt/open-falcon/back/nodata/config/cfg.json "config": { "enabled": true, "dsn": "root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true&wait_timeout=604800", "maxIdle": 4 }, ⑤、vim /opt/open-falcon/back/api/config/cfg.json { "log_level": "debug", "db": { "falcon_portal": "root:passwd@tcp(127.0.0.1:3306)/falcon_portal?charset=utf8&parseTime=True&loc=Local", "graph": "root:passwd@tcp(127.0.0.1:3306)/graph?charset=utf8&parseTime=True&loc=Local", "uic": "root:passwd@tcp(127.0.0.1:3306)/uic?charset=utf8&parseTime=True&loc=Local", "dashboard": "root:passwd@tcp(127.0.0.1:3306)/dashboard?charset=utf8&parseTime=True&loc=Local", "alarms": "root:passwd@tcp(127.0.0.1:3306)/alarms?charset=utf8&parseTime=True&loc=Local", "db_bug": true }, ⑥、vim /opt/open-falcon/back/alarm/config/cfg.json "falcon_portal": { "addr": "root:passwd@tcp(127.0.0.1:3306)/alarms?charset=utf8&loc=Local", "idle": 10, "max": 100 },

5、启动后端

cd /opt/open-falcon/back /open-falcon start

三、部署前端

1、设置临时位置变量

export FRONTSPACE=/opt/open-falcon/front

2、创建工作目录

mkdir -p $FRONTSPACE

3、从github上克隆前端源码

cd $FRONTSPACE git clone http://github.com/open-falcon/dashboard.git

4、安装依赖

yum install -y python-virtualenv yum install -y python-devel yum install -y openldap-devel yum install -y mysql-devel yum groupinstall -y "Development tools" # 通过virtualenv创建目录env作为独立的运行环境 cd $FRONTSPACE/dashboard virtualenv /env # 生成 requirements.txt 并安装依赖 /env/bin/pip install -r pip_requirements.txt

5、编辑dashboard配置文件config.py

29 # portal database 30 # TODO: read from api instead of db 31 PORTAL_DB_HOST = os.environ.get("PORTAL_DB_HOST","127.0.0.1") 32 PORTAL_DB_PORT = int(os.environ.get("PORTAL_DB_PORT",3306)) 33 PORTAL_DB_USER = os.environ.get("PORTAL_DB_USER","root") 34 PORTAL_DB_PASS = os.environ.get("PORTAL_DB_PASS","passwd") 35 PORTAL_DB_NAME = os.environ.get("PORTAL_DB_NAME","falcon_portal")

6、启动前端

cd $FRONTSPACE/dashboard bash control start

四、使用openfalcon

1、访问openfalcon页面

浏览器访问http://服务器IP地址:8081

PS：具体的监控项添加参考官方文档：http://book.open-falcon.org/zh/
