open-falcon v0.1升级v0.2
v0.1环境变量：
export HOME=/home/neo
export WORKSPACE=$HOME/open-falcon
export GOPATH=$HOME/workspace
#export GOROOT=$HOME/go
#export PATH=$GOROOT/bin:$GOPATH/bin:$PATH
v0.2 准备新的数据库
数据库脚本地址：https://github.com/open-falcon/falcon-plus/blob/master/scripts/mysql/db_schema/5_alarms-db-schema.sql
mysql -u root < 5_alarms-db-schema.sql
下载v0.2版本的二进制程序
cd ~ && wget https://github.com/open-falcon/falcon-plus/releases/download/v0.2.0/open-falcon-v0.2.0.tar.gz
mkdir open-falcon-v0.2 && tar xf open-falcon-v0.2.0.tar.gz -C open-falcon-v0.2
升级思路：
官方文档提示只需要替换二进制文件即可，在实际的测试环境下，不可以。
比方说：agent v0.1版本目录下，无config和bin目录，而agent v0.2版本是需要在agent/config目录下查找配置文件，
且v0.2版本，在启动agent时，需要调用agent/bin/falcon-agent 此二进制文件运行。
操作简单的升级思路是：直接将各个组件目录先备份，重命名，将v0.2版本的目录重命名正常，且先修改配置文件即可。
升级agent

cd ~/open-falcon && mv agent agent-v0.1

# 启动服务，v0.2版本，可以由open-falcon统一管理服务，
cd ~/open-falcon
./open-falcon [ check | help | monitor | reload | restart | start | stop ]

~/open-falcon/open-falcon check

falcon-nodata DOWN -
falcon-aggregator DOWN -
falcon-agent UP 24014
falcon-gateway DOWN -

升级transfer(同样的，目录结构变化，升级思路与agent一致)
# transfer的配置文件无需改变
mv ~/open-falcon/transfer ~/open-falcon/transfer-v0.1
cp ~/open-falcon-v0.2/transfer ~/open-falcon/transfer
~/open-falcon/open-falcon stop transfer
~/open-falcon/open-falcon start transfer
升级graph
# 配置文件无需改变，直接用graph的v0.2版本替换
cd ~/open-falcon && mv graph graph-v0.1
cp -r ../open-falcon-v0.2/graph ./
./open-falcon stop graph
./open-falcon start graph
./open-falcon check
升级query模块(api模块替换)
v2版本是将api模块，代替query模块
cd ~/open-falcon && ./query/control stop #停止query服务
mv query query-v0.1
cp -r ../open-falcon-v0.2/api ./
./open-falcon start api
./open-falcon check
升级hbs模块
cd ~/open-falcon && mv hbs hbs-v0.1
cp -r ../open-falcon-v0.2/hbs ./
./open-falcon stop hbs
./open-falcon start hbs
升级judge
cd ~/open-falcon && mv judge judge-v0.1
cp -r ../open-falcon-v0.2/judge ./
./open-falcon stop judge
./open-falcon start judge
./open-falcon check
升级alarm
# alarm的配置文件：alarm/config/cfg.json

升级gateway
升级dashboard (全新安装)
# 全新安装

yum install -y python-virtualenv
yum install -y python-devel
yum install -y openldap-devel

virtualenv ./env
./env/bin/pip install -r pip_requirements.txt -i http://mirrors.aliyun.com/pypi/simple # -i 指定pip的源
# 配置，图形展示工具grafana拉去open-falcon数据源的API地址：
vim rrd/config.py
API_ADDR = "http://127.0.0.1:8080/api/v1" # 默认接口地址
# 修改配置信息，如数据库密码等信息
