centos7系統open-falcon安裝流程圖解（單機安裝，docker安裝，分佈式安裝）

open-falcon

open-falcon的目標是做最開放、最好用的互聯網企業級監控產品。

1、單機安裝

1.1、搭建golang語言環境

下載golang

根據操作系統下載golang對應的RPM包：
https://pkgs.org/download/golang

golang-1.13.3-1.el7.x86_64.rpm
golang-bin-1.13.3-1.el7.x86_64.rpm
golang-src-1.13.3-1.el7.noarch.rpm

安裝golang

yum install gcc
yum install git
yum install subversion
yum install mercurial

go version

配置GOPATH和GOROOT環境變量

go env

1.2、搭建運行環境

安裝redis

yum install -y epel-release
yum install -y redis

安裝mysql-server

yum -y install wget
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install -y mysql-server

1.3、安裝Falcon

下載Falcon

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

初始化數據庫

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

編譯

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

# make all modules
make all

# make specified module
make agent

# pack all modules
make pack

執行完畢make pack 會在當前目錄下生成一個open-falcon-vx.x.x.tar.gz

1.4、運行啓動Falcon

將open-falcon-vx.x.x.tar.gz複製到運行目錄下，解壓

啓動

./open-falcon start

檢查狀態

# check modules status
./open-falcon check

1.4、運行啓動Frontend Dashboard

下載Dashboard

cd /root/open-falcon/
git clone https://github.com/open-falcon/dashboard.git
cd dashboard

dashboard config file is ‘rrd/config.py’

安裝運行環境

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 /root/open-falcon/dashboard/
virtualenv ./env

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

在開發者模式下運行

source ./env/bin/python wsgi.py
export FLASK_ENV=development
flask run --host=0.0.0.0 --port=8081

在生產模式下運行

Run with gunicorn in production mode

bash control start

訪問

open http://127.0.0.1:8081 in your browser.
dashbord沒有默認創建任何賬號包括管理賬號，需要通過頁面進行註冊賬號。
想擁有管理全局的超級管理員賬號，需要手動註冊用戶名爲root的賬號（第一個帳號名稱爲root的用戶會被自動設置爲超級管理員）
超級管理員可以給普通用戶分配權限管理。

小提示：註冊賬號能夠被任何打開dashboard頁面的人註冊，所以當給相關的人註冊完賬號後，需要去關閉註冊賬號功能。只需要去修改api組件的配置文件cfg.json，將signup_disable配置項修改爲true，重啓api即可。當需要給人開賬號的時候，再將配置選項改回去，用完再關掉即可。

2、Docker安裝

docker run -itd \
        --name falcon-mysql \
        -v /root/open_falcon/mysql-data:/var/lib/mysql \
        -e MYSQL_ALLOW_EMPTY_PASSWORD=true \
        -p 3306:3306 \
        mysql:5.7

git clone --depth=1 https://github.com/open-falcon/falcon-plus
cd /root/open_falcon/falcon-plus

#!/bin/sh

for x in `ls ./scripts/mysql/db_schema/*.sql`; do
    echo init mysql table $x ...;
    docker exec -i falcon-mysql mysql -uroot < $x;
done

docker run --name falcon-redis -p6379:6379 -d redis:4-alpine3.8

docker run -itd --name falcon-plus \
     --link=falcon-mysql:db.falcon \
     --link=falcon-redis:redis.falcon \
     -p 8433:8433 \
     -p 8080:8080 \
     -e MYSQL_PORT=root@tcp\(db.falcon:3306\) \
     -e REDIS_PORT=redis.falcon:6379  \
     -v /root/open_falcon/open-falcon/data:/open-falcon/data \
     -v /root/open_falcon/open-falcon/logs:/open-falcon/logs \
     openfalcon/falcon-plus:v0.3

docker exec falcon-plus sh ctrl.sh start graph hbs judge transfer nodata aggregator agent gateway api alarm

docker run -itd --name falcon-dashboard \
        -p 8081:8081 \
        --link=falcon-mysql:db.falcon \
        --link=falcon-plus:api.falcon \
        -e API_ADDR=http://api.falcon:8080/api/v1 \
        -e PORTAL_DB_HOST=db.falcon \
