搭建小米的监控系统：open-falcon
SofM 2020-01-06 15:12:49
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
yuminstall -y wget vim git
3、安装golang、redis
yuminstall-y epel-release
yuminstall-y golang
yuminstall-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
exportGOROOT=/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 https://github.com/open-falcon/falcon-plus.git
7、初始化数据库
cd$GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema
#执行5个脚本初始化数据库，提示“Enterpassword”，如果mysql的root没有设置密码，回车即可
mysql-h127.0.0.1-uroot-p<1_uic-db-schema.sql
mysql-h127.0.0.1-uroot-p<2_portal-db-schema.sql
mysql-h127.0.0.1-uroot-p<3_dashboard-db-schema.sql
mysql-h127.0.0.1-uroot-p<4_graph-db-schema.sql
mysql-h127.0.0.1-uroot-p<5_alarms-db-schema.sql
8、编译后端源码
cd$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
exportBACKSPACE=/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 -xzvfopen-falcon-v0.2.1.tar.gz -C $BACKSPACE
4、修改各模块配置文件cfg.json
①、vim /opt/open-falcon/back/aggregator/config/cfg.json
"database": {
"addr":"root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true",
"idle":10,
"ids": [1, -1],
"interval":55
②、vim /opt/open-falcon/back/graph/config/cfg.json
"db": {
"dsn":"root:passwd@tcp(127.0.0.1:3306)/graph?loc=Local&parseTime=true",
"maxIdle":4
},
③、vim /opt/open-falcon/back/hbs/config/cfg.json
{
"debug": true,
"database":"root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true",
"hosts":"",
"maxConns":20,
"maxIdle":15,
"listen":":6030",
"trustable": [""],
"http": {
"enabled": true,
"listen":"0.0.0.0:6031"
}
}
④、vim /opt/open-falcon/back/nodata/config/cfg.json
"config": {
"enabled": true,
"dsn":"root:passwd@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true&wait_timeout=604800",
"maxIdle":4
},
⑤、vim /opt/open-falcon/back/api/config/cfg.json
{
"log_level":"debug",
"db": {
"falcon_portal":"root:passwd@tcp(127.0.0.1:3306)/falcon_portal?charset=utf8&parseTime=True&loc=Local",
"graph":"root:passwd@tcp(127.0.0.1:3306)/graph?charset=utf8&parseTime=True&loc=Local",
"uic":"root:passwd@tcp(127.0.0.1:3306)/uic?charset=utf8&parseTime=True&loc=Local",
"dashboard":"root:passwd@tcp(127.0.0.1:3306)/dashboard?charset=utf8&parseTime=True&loc=Local",
"alarms":"root:passwd@tcp(127.0.0.1:3306)/alarms?charset=utf8&parseTime=True&loc=Local",
"db_bug": true
},
⑥、vim /opt/open-falcon/back/alarm/config/cfg.json
"falcon_portal": {
"addr":"root:passwd@tcp(127.0.0.1:3306)/alarms?charset=utf8&loc=Local",
"idle":10,
"max":100
},
5、启动后端
cd /opt/open-falcon/back
./open-falcon start
三、部署前端
1、设置临时位置变量
exportFRONTSPACE=/opt/open-falcon/front
2、创建工作目录
mkdir-p$FRONTSPACE
3、从github上克隆前端源码
cd$FRONTSPACE
gitclonehttps://github.com/open-falcon/dashboard.git
4、安装依赖
yuminstall-y python-virtualenv
yuminstall-y python-devel
yuminstall-y openldap-devel
yuminstall-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 $FRONTSPACE/dashboard
virtualenv ./env
# 生成 requirements.txt 并安装依赖
./env/bin/pip install -r pip_requirements.txt
5、编辑dashboard配置文件config.py
29# portal database
30# TODO:readfrom api instead of db
31PORTAL_DB_HOST =os.environ.get("PORTAL_DB_HOST","127.0.0.1")
32PORTAL_DB_PORT = int(os.environ.get("PORTAL_DB_PORT",3306))
33PORTAL_DB_USER =os.environ.get("PORTAL_DB_USER","root")
34PORTAL_DB_PASS =os.environ.get("PORTAL_DB_PASS","passwd")
35PORTAL_DB_NAME =os.environ.get("PORTAL_DB_NAME","falcon_portal")
6、启动前端
cd$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：
