open falcon 开源监控环境搭建

写在前面的话

每篇一句

苟有恒，何必三更眠五更起，最无益，莫过一日曝十日寒。

监控部署

go 安装

1
2
3

cd /data/
wget https://storage.googleapis.com/golang/go1.9.1.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.9.1.linux-amd64.tar.gz

/root/.bashrc 文件增加go环境变量配置,针对root用户配置环境变量。如果想所有用户使用可追加在/etc/profile。

1
2
3

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

使环境变量立即生效

1	source /root/.bashrc

验证

1 2	[root@openfalon_zzq_host ~]# go version go version go1.9.1 linux/amd64

查看所有go 环境变量可使用go env

安装redis

[root@openfalon_zzq_host ~]# yum install -y redis
