单体安装 open-falcon

下载

https://github.com/open-falcon/falcon-plus/releases/download/v0.3/open-falcon-v0.3.tar.gz

https://github.com/open-falcon/falcon-plus/releases/download/v0.2.1/open-falcon-v0.2.1.tar.gz

一、创建工作目录

export FALCON_HOME=/data/work

export WORKSPACE=$FALCON_HOME/open-falcon

mkdir -p $WORKSPACE

二、解压二进制包

cd /data/software

tar -xzvf open-falcon-v0.3.tar.gz -C $WORKSPACE

三、配置数据库账号和密码

cd $WORKSPACE

grep -Ilr 3306 ./ | xargs -n1 -- sed -i 's/root:/root:root12/g'
grep -Ilr 6379 ./ | xargs -n1 -- sed -i 's/127.0.0.1:6379/127.0.0.1:6491/g'

四、启动

查看目录下包括Open-Falcon的所有组件，我们先默认全部启动，之后我们一个一个讲解如何分布式部署以及启动

[root@master open-falcon]# ls
agent  aggregator  alarm  api  gateway  graph  hbs  judge  nodata  open-falcon  plugin  public  transfer

./open-falcon start

./open-falcon start
[falcon-graph] 15489
[falcon-hbs] 15494
[falcon-judge] 15521
[falcon-transfer] 15531
[falcon-nodata] 15534
[falcon-aggregator] 15551
[falcon-agent] 15554
[falcon-gateway] 15569
[falcon-api] 15576
[falcon-alarm] 15586

• 检查所有模块的启动状况

./open-falcon check

./open-falcon check
        falcon-graph       DOWN               - 
          falcon-hbs       DOWN               - 
        falcon-judge         UP           15521 
     falcon-transfer         UP           15531 
       falcon-nodata       DOWN               - 
   falcon-aggregator       DOWN               - 
        falcon-agent         UP           15554 
      falcon-gateway         UP           15569
