【监控】open-falcon v0.2 部署、小米开源监控部署

所依赖其他服务

• memcached

• redis

yum安装即可

go环境配置

• 下载go

cd /usr/local/src
wget https://golang.org/doc/install?download=go1.5.2.linux-amd64.tar.gz

• 解包

cd /usr/local/src
tar -C /usr/local -xzf go1.5.2.linux-amd64.tar.gz

• 新建gopath

mkdir /usr/local/gopkg

• 配置go环境变量

vim /etc/profile

• 添加如下信息

export GOROOT=/usr/local/go
export GOPATH=/usr/local/gopkg
export PATH=$GOROOT/bin:$PATH

• 刷新配置文件：

source /etc/profile

• 查看go版本：

[root@codis01 ~]#go version
go version go1.5.2 linux/amd64

编译open-falcon

cd $GOPATH/src/github.com/open-falcon/
git clone https://github.com/open-falcon/falcon-plus.git

make all

make pack

这时候，你会在当前目录下面，得到open-falcon-v0.2.0.tar.gz的压缩包，就表示已经编译和打包成功了。

安装open-falcon

cp $GOPATH/src/github.com/open-falcon/falcon-plus/open-falcon-v0.2.0.tar.gz /usr/local/src

cd /usr/local/src/
tar zxvf open-falcon-v0.2.0.tar.gz -C /usr/local/open-falcon

修改配置文件

open-falcon每个组件的配置文件都存放在该目录下的config下，修改相应地址与数据库信息即可

导入数据库

cd /usr/local/src/ && git clone https://github.com/open-falcon/falcon-plus.git 
cd /usr/local/src/falcon-plus/scripts/mysql/db_schema/

mysql -h 127.0.0.1 -uroot -p < 1_uic-db-schema.sql
mysql -h 127.0.0.1 -uroot -p < 2_portal-db-schema.sql
mysql -h 127.0.0.1 -uroot -p < 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -uroot -p < 4_graph-db-schema.sql
mysql -h 127.0.0.1 -uroot -p < 5_alarms-db-schema.sql
