open-falcon 是小米開源的運維繫統後臺為golang開發，正常情況下按照官方文件說明就可以搭建成功。

一、後臺程式編譯安裝

1、環境準備

• Git >= 1.7.5
• Go >= 1.6
• yum install  redis
• yum install  mysql

如果redis與mysql環境已經安裝，可在配置檔案配置。

2、下載原始碼（open-falcon有0.1與0.2版本，0.1版本各個模組獨立執行，非常不方便，0.2版本各個模組整合，編譯打包很方便）

# Please make sure that you have set `$GOPATH` and `$GOROOT` correctly.
# If you have not golang in your host, please follow [https://golang.org/doc/install] to install golang.

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

 資料庫初始化 

cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql
 

3、編譯打包

cd $GOPATH/src/github.com/open-falcon/falcon-plus/

# make all modules
make all

# make specified module
make agent

# pack all modules
make pack

說明：直接執行時會提示配置檔案或執行檔案目錄不對，但是打包檔案解壓可正常執行./g/g.go檔案可對執行檔案與配置檔案路徑進行編輯。

4、解壓執行

export WorkDir="$HOME/open-falcon"
mkdir -p $WorkDir
tar -xzvf open-falcon-vx.x.x.tar.gz -C $WorkDir
cd $WorkDir


cd $WorkDir
./open-falcon start

# check modules status
./open-falcon check
 

5、狀態檢視

# ./open-falcon [start|stop|restart|check|monitor|reload] module
./open-falcon start agent

./open-falcon check
        falcon-graph         UP           53007
          falcon-hbs         UP           53014
        falcon-judge         UP           53020
     falcon-transfer         UP           53026
       falcon-nodata         UP           53032
   falcon-aggregator         UP           53038
        falcon-agent         UP           53044
      falcon-gateway         UP           53050
          falcon-api         UP           53056
        falcon-alarm         UP           53063

6、上面執行是所有模組都運行了，一般只有運維伺服器需要執行這些模組，監控端只需要執行agent模組即可。

二、前端安裝

1、open-falcon採用前後端分離，前端dashboard為另外一個專案https://github.com/open-falcon/dashboard，支援docker與i18n，原始碼執行，為python環境

2、下載檔案

export HOME=/home/work/

mkdir -p $HOME/open-falcon/
cd $HOME/open-falcon && git clone https://github.com/open-falcon/dashboard.git
cd dashboard;

3、安裝依賴

CentOS
yum install -y python-virtualenv
yum install -y python-devel
yum install -y openldap-devel
yum install -y mysql-devel
yum groupinstall "Development tools"


cd $HOME/open-falcon/dashboard/
virtualenv ./env

./env/bin/pip install -r pip_requirements.txt
Ubuntu
apt-get install -y python-virtualenv
apt-get install -y slapd ldap-utils
apt-get install -y libmysqld-dev
apt-get install -y build-essential
apt-get install -y python-dev libldap2-dev libsasl2-dev libssl-dev

cd $HOME/open-falcon/dashboard/
virtualenv ./env

./env/bin/pip install -r pip_requirements.txt

4、初始化資料庫，步驟與後臺安裝是一致，若前面已經初始化，此步驟可以省略

5、配置後臺介面rrd/config.py

dashboard config file is 'rrd/config.py', change it if necessary.

## set API_ADDR to your falcon-plus api modules addr, default value as bellow:
API_ADDR = "http://127.0.0.1:8080/api/v1" 

## set PORTAL_DB_* if necessary, default mysql user is root, default passwd is ""
## set ALARM_DB_* if necessary, default mysql user is root, default passwd is ""
## if following error msg occurred, please check DB config in rrd/config.py

Error 'NoneType' object has no attribute 'cursor'

6、執行

 control start

  在瀏覽器中輸入http://ip:8081/能訪問則說明前端執行正常，首次登陸需要自己註冊使用者。

  前面簡單的安裝就成功了， 官方文件非常清晰，但是後面如何使用還要慢慢研究。
