Open-Falcon部署分为前端（客户端）和后端（服务端）
参考官方文档：https://book.open-falcon.org/zh_0_2/quick_install/prepare.html
一 后端（服务端）部署
1、系统环境
[root@open-falcon-server ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
2、软件环境准备
2.1 安装 redis
#安装
yum install redis -y
#redis常用命令
redis-server redis 服务端
redis-cli redis 命令行客户端
redis-benchmark redis 性能测试工具
redis-check-aof AOF文件修复工具
redis-check-dump RDB文件修复工具
redis-sentinel Sentinel 服务端
#启动redis
[root@open-falcon-server ~]# redis-server
2.2 安装mysql
#安装mysql
[root@open-falcon-server ~]#wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
[root@open-falcon-server ~]# ll
[root@open-falcon-server ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
[root@open-falcon-server ~]# ll /etc/yum.repos.d/
[root@open-falcon-server ~]#yum install -y mysql-serve
#启动mysql并设置开机自启动
[root@open-falcon-server ~]# systemctl start mysqld.service
[root@open-falcon-server ~]# systemctl enable mysqld.service
[root@open-falcon-server ~]# mysql -uroot -p
（没有密码）
mysql> exit
#检查服务
netstat -lntup
#初始化MySQL表结构（备注：导入表结构后，注意检查）
cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git
cd /tmp/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
rm -rf /tmp/falcon-plus/
#设置数据库密码 (备注：用户名：root ,密码: password )
[root@open-falcon-server open-falcon]# mysqladmin -uroot password "password"
#检查导入的数据库表
[root@open-falcon-server open-falcon]# mysql -uroot -p
mysql> show databases;
information_schema | | alarms | | dashboard | | falcon_portal | | graph | | mysql | | performance_schema | | uicmysql> exit
2.3配置Go语言开发环境
#安装go语言开发包（备注：安装需要epel源）
yum install golang -y
补充：epel源
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
ll
rpm -ivh epel-release-latest-7.noarch.rpm
#检查版本
[root@open-falcon-server ~]# go version
#查看go的安装路径
[root@open-falcon-server ~]# find / -name go
/etc/alternatives/go
/var/lib/alternatives/go
/usr/bin/go
/usr/lib/golang/src/cmd/go #需要的是这个路径
/usr/lib/golang/src/go
/usr/lib/golang/bin/go
/usr/lib/golang/pkg/linux_amd64/go
#设置环境变量GOROOT和GOPATH
vi /etc/profile
export GOROOT=/usr/lib/golang
export GOPATH=/home
source /etc/profile
3.下载编译好的二进制版本
直接下载官方编译好的二进制版本(x86 64位平台)。
https://github.com/open-falcon/falcon-plus/releases
#开始安装open-falcon
[root@open-falcon-server ~]# export FALCON_HOME=/home/work
[root@open-falcon-server ~]# export WORKSPACE=$FALCON_HOME/open-falcon
[root@open-falcon-server ~]# mkdir -p $WORKSPACE
#上传软件
[root@open-falcon-server ~]# ll
-rw-r--r--. 1 root root 40031472 Oct 29 2017 open-falcon-v0.2.1.tar.gz
#解压
[root@open-falcon-server ~]# tar -xf open-falcon-v0.2.1.tar.gz -C $WORKSPACE
[root@open-falcon-server ~]# cd $WORKSPACE
#查看解压结果
[root@open-falcon-server open-falcon]# ll

drwxrwxr-x. 5 501 501 40 Aug 15 19:16 transfer
4.修改配置文件cfg.json
部分模块依赖连接数据库，因为如果不修改配置文件，aggregator模块会出现无法启动，graph、hbs、nodata、api、alarm模块会出现开启不报错但是状态为开启失败的情况。
如果需要每个模块都能正常启动，需要将上面模块的cfg.json的数据库信息进行修改。需要修改配置文件所在的目录：
1）修改aggregator的配置文件
vim /home/work/aggregator/config/cfg.json
2）修改graph的配置文件
vim /home/work/graph/config/cfg.json
3）修改hbs的配置文件
vim /home/work/hbs/config/cfg.json
4）修改nodata的配置文件
vim /home/work/nodata/config/cfg.json
5）修改api的配置文件
vim /home/work/api/config/cfg.json
6）修改alarm的配置文件
vim /home/work/alarm/config/cfg.json
5.启动后端模块
[root@open-falcon-server open-falcon]# cd /home/work/open-falcon
#启动服务
[root@open-falcon-server open-falcon]# ./open-falcon start
#检查服务启动状态
[root@open-falcon-server open-falcon]# ./open-falcon check
#更多的命令行工具用法
# ./open-falcon [start|stop|restart|check|monitor|reload] module
./open-falcon start agent
#For debugging , You can check $WorkDir/$moduleName/log/logs/xxx.log
6.其它用法
#重载配置（备注：修改vi cfg.json配置文件后，可以用下面命令重载配置）
curl 127.0.0.1:1988/config/reload
二 前端部署 （备注：在另外一台服务器上面操作）
1、创建工作目录
export HOME=/home/work
export WORKSPACE=$HOME/open-falcon
mkdir -p $WORKSPACE
cd $WORKSPACE
2、克隆前端组件代码
git clone https://github.com/open-falcon/dashboard.git
3、安装依赖包
yum install -y python-virtualenv
yum install -y python-devel
yum install -y openldap-devel
yum install -y mysql-devel
yum groupinstall "Development tools" -y
cd $WORKSPACE/dashboard/
virtualenv ./env
./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple
#配置说明：
dashboard的配置文件为： 'rrd/config.py'，请根据实际情况修改
## API_ADDR 表示后端api组件的地址
API_ADDR = "http://127.0.0.1:8080/api/v1"
## 根据实际情况，修改PORTAL_DB_*, 默认用户名为root，默认密码为""
## 根据实际情况，修改ALARM_DB_*, 默认用户名为root，默认密码为""
#修改方法
[root@Open-Falcon-client]#cd /home/work/open-falcon/dashboard/rrd
[root@Open-Falcon-client rrd]# cp config.py config.py.bak
(env)[root@Open-Falcon-client rrd]# vi config.py
