Open-Falcon部署以及配置

Open-Falcon是做什么的这里就不多描述了，可以参考一下官方的解释，（http://book.open-falcon.org/zh_0_2/intro/）这里是2.0的版本，本人在本地做了一些测试，单价安装和分布式安装的区别在这里说一下，单机安装只是把所有组件安装在一台机器上，分布式安装时组件分别安装在不同的机器上，这里不建议一个组件安装在一台机器上，如果想选择高可用，可以进行交叉安装，只是在组件的端口需要自己修改一下，记得一定要在做之前规划好，组件多端口也多，不然容易混淆。下面是我的单机安装实验：

环境准备

[root@localhost ~]# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@localhost ~]# rpm -ivh epel-release-latest-7.noarch.rpm 
[root@localhost ~]# yum install -y redis
[root@localhost ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
[root@localhost ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

[root@open-falcon-server ~]# yum install -y mysql-server
[root@open-falcon-server ~]# cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git 
[root@open-falcon-server tmp]# cd /tmp/falcon-plus/scripts/mysql/db_schema/

安装后一定要启动，！！！！！

默认mysql是没有密码的，所以需要给mysql的管理员设置一个密码，让后把open-falcon的数据导入到mysql中。

[root@open-falcon-server db_schema]# mysql -uroot -p

重启一下mysql，然后从新使用密码登录进去，并把需要使用的mysql导入进去，这里应用和mysql使用的是一台机器，就不设置mysql客户端授权，如果不同需要设置授权连接账号和密码。

导入的库已经完成，这里要记住如果是从v0.1.0升级到v0.2.0只需要到入5_alarms-db-schema.sql即可，因为其他库已经存在了。

安装依赖go

因为open-falcon依赖go进行编译，所以需要使用go环境，下面是安装go的方法：

下载源码包

[root@open-falcon-server ~]# wget https://dl.google.com/go/go1.13.5.linux-amd64.tar.gz
[root@open-falcon-server ~]# tar -zxf go1.13.5.linux-amd64.tar.gz 
[root@open-falcon-server ~]# mv go /usr/local/
[root@open-falcon-server ~]# mkdir /opt/go

设置环境变量

[root@open-falcon-server ~]# vim /etc/profile
...........................................
export GOROOT=/usr/local/go 
export GOBIN=$GOROOT/bin
export GOPKG=$GOROOT/pkg/tool/linux_amd64 
export GOARCH=amd64
export GOOS=linux
export GOPATH=/opt/go
export PATH=$PATH:$GOBIN:$GOPKG:$GOPATH/bin
[root@open-falcon-server ~]# source /etc/profile

测试一下

[root@open-falcon-server ~]# go version
go version go1.13.3 linux/amd64

下载open-falcon源码包，然后进行编译

[root@open-falcon-server ~]# mkdir -p $GOPATH/src/github.com/open-falcon
[root@open-falcon-server ~]# cd $GOPATH/src/github.com/open-falcon
[root@open-falcon-server open-falcon]# git clone https://github.com/open-falcon/falcon-plus.git

安装前端

设置一下基本环境

[root@open-falcon-server alarm]# export HOME=/home/work
[root@open-falcon-server alarm]# export WORKSPACE=$HOME/open-falcon
[root@open-falcon-server alarm]# mkdir -p $WORKSPACE
[root@open-falcon-server alarm]# cd $WORKSPACE
[root@open-falcon-server open-falcon]# cd $WORKSPACE
[root@open-falcon-server open-falcon]# git clone https://github.com/open-falcon/dashboard.git

安装依赖包

安装前端服务器之前先安装一下依赖包，因为是python开发的，所以需要安装pip的模块。

[root@open-falcon-server open-falcon]# yum install -y python-virtualenv
[root@open-falcon-server open-falcon]# yum install -y python-devel
[root@open-falcon-server open-falcon]# yum install -y openldap-devel
[root@open-falcon-server open-falcon]# yum install -y mysql-devel
[root@open-falcon-server open-falcon]# yum groupinstall "Development tools"
[root@open-falcon-server open-falcon]# cd $WORKSPACE/dashboard/
[root@open-falcon-server dashboard]# virtualenv ./env
New python executable in /home/work/open-falcon/dashboard/env/bin/python
Installing setuptools, pip, wheel...done.
[root@open-falcon-server dashboard]# ./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple

配置客户端连接数据库信息：

[root@open-falcon-server dashboard]# vim rrd/config.py
.....................................................
# portal database
# TODO: read from api instead of db
PORTAL_DB_HOST = os.environ.get("PORTAL_DB_HOST","127.0.0.1")
PORTAL_DB_PORT = int(os.environ.get("PORTAL_DB_PORT",3306))
PORTAL_DB_USER = os.environ.get("PORTAL_DB_USER","root")
PORTAL_DB_PASS = os.environ.get("PORTAL_DB_PASS","root")
PORTAL_DB_NAME = os.environ.get("PORTAL_DB_NAME","falcon_portal")

# alarm database
# TODO: read from api instead of db
ALARM_DB_HOST = os.environ.get("ALARM_DB_HOST","127.0.0.1")
ALARM_DB_PORT = int(os.environ.get("ALARM_DB_PORT",3306))
ALARM_DB_USER = os.environ.get("ALARM_DB_USER","root")
ALARM_DB_PASS = os.environ.get("ALARM_DB_PASS","root")
ALARM_DB_NAME = os.environ.get("ALARM_DB_NAME","alarms")
............................................................

启动前端服务

以开发者模式启动

./env/bin/python wsgi.py

生产环境启动

bash control start
bash control stop
bash control tail #查看日志

客户端部署

open-falcon服务端已经安装完成，下面我们安装客户端，这里提示一下服务端安装之后已经自带了客户端，为了方便，我们把客户端的agent拷贝到其他机器上即可，然后配置一下指定到服务端启动一下即可。

[root@open-falcon-server open-falcon]# pwd
/home/work/open-falcon
[root@open-falcon-server open-falcon]# cp open-falcon agent/
[root@open-falcon-server open-falcon]# scp -r agent root@10.211.55.140:/home/work

首先需要把启动的文件copy到客户端目录下，方便客户端启动，然后在把数据传输到客户端上了，我们在客户端上配置一下，指向server，然后启动。

[root@open-falcon-agent config]# pwd
/home/work/agent/config
[root@open-falcon-agent config]# vim cfg.json 
{
	"debug": true,
	"hostname": "",
	"ip": "",
	"plugin": {
		"enabled": false,
		"dir": "./plugin",
		"git": "https://github.com/open-falcon/plugin.git",
		"logs": "./logs"
	},
	"heartbeat": {
		"enabled": true,
		"addr": "10.211.55.141:6030",
		"interval": 60,
		"timeout": 1000
	},
	"transfer": {
		"enabled": true,
		"addrs": [
			"10.211.55.141:8433"
		],
		"interval": 60,
		"timeout": 1000
	},
	"http": {
		"enabled": true,
		"listen": ":1988",
		"backdoor": false
	},
	"collector": {
		"ifacePrefix": ["eth", "em"],
		"mountPoint": []
	},
	"default_tags": {
	},
	"ignore": {
		"cpu.busy": true,
		"df.bytes.free": true,
		"df.bytes.total": true,
		"df.bytes.used": true,
		"df.bytes.used.percent": true,
		"df.inodes.total": true,
		"df.inodes.free": true,
		"df.inodes.used": true,
		"df.inodes.used.percent": true,
		"mem.memtotal": true,
		"mem.memused": true,
		"mem.memused.percent": true,
		"mem.memfree": true,
		"mem.swaptotal": true,
		"mem.swapused": true,
		"mem.swapfree": true
	}
}

[root@open-falcon-agent config]# cd ../..
[root@open-falcon-agent work]# ./agent/open-falcon start agent

启动成功，下面看一下前端是否有接受到新的客户端。到此，Open-Falcon的部署已经完成，下一章就是前端报警的设置了。
