1、Open-Falcon介紹

一、監控系統，能夠從運營級別（基本配置便可），以及應用級別（二次開發，經過端口進行日誌上報），對服務器、操做系統、中間件、應用進行全面的監控，及報警，對咱們的系統正常運行的做用很是重要。前端

二、基礎監控java

CPU、Load、內存、磁盤、IO、網絡相關、內核參數、ss 統計輸出、端口採集、核心服務的進程存活信息採集、關鍵業務進程資源消耗、NTP offset採集、DNS解析採集，這些指標，都是open-falcon的agent組件直接支持的。python

Linux運維基礎採集項：http://book.open-falcon.org/zh/faq/linux-metrics.htmlmysql

對於這些基礎監控選項所有理解透徹的時刻，也就是對Linux運行原理及命令進階的時刻。linux

三、第三方監控ios

術業有專攻，運行在OS上的應用甚多，Open-Falcon的開發團隊不可能把全部的第三方應用的監控所有作完，這個就須要開源社區提供更多的插件，當前對於不少經常使用的第三方應用都有相關插件了。git

四、JVM監控github

對於Java做爲主要開發語言的大多數公司，對於JVM的監控不可或缺。golang

每一個JVM應用的參數，好比GC、類加載、JVM內存、進程、線程，均可以上報給Falcon，而這些參數的得到，均可以經過MxBeans實現。

使用 Java 平臺管理 bean：http://www.ibm.com/developerworks/cn/java/j-mxbeans/

五、業務應用監控

對於業務須要監控的接口，好比響應時間等。能夠根據業務的須要，上報相關數據到Falcon，並經過Falcon查看結果。

2、Zabbix、Nagios、Open-Falcon這3大開源運維監控工具的比較

 

3、Open-Falcon編寫的整個腦洞歷程

說明：Open-Falcon部署分爲前端（客戶端）和後端（服務端）

4、後端部署（服務端）

參考官方文檔：https://book.open-falcon.org/zh_0_2/quick_install/prepare.html

一、系統環境

[root@ open -falcon-server ~] # cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

二、系統優化

#安裝下載軟件
yum install  wget -y
 
#更換aliyun源
mv  /etc/yum .repos.d /CentOS-Base .repo /etc/yum .repos.d /CentOS-Base .repo.backup
wget -O /etc/yum .repos.d /CentOS-Base .repo http: //mirrors .aliyun.com /repo/Centos-7 .repo
 
#下載epel源
yum install  epel-release.noarch -y
rpm -Uvh http: //mirrors .aliyun.com /epel/epel-release-latest-7 .noarch.rpm
yum clean all
yum makecache
 
#下載經常使用軟件
yum install  git telnet net-tools tree nmap sysstat lrzsz dos2unix tcpdump ntpdate -y
 
#配置時間同步
ntpdate cn.pool.ntp.org
 
#更改主機名
hostnamectl set - hostname  open -falcon-server
hostname  open -falcon-server
 
#開啓緩存
sed  -i 's#keepcache=0#keepcache=1#g'  /etc/yum .conf
grep  keepcache /etc/yum .conf
 
#關閉selinux
sed  -i 's/SELINUX=enforcing/SELINUX=disabled/g'  /etc/selinux/config
setenforce 0
 
#關閉防火牆
systemctl stop firewalld.service
systemctl disable firewalld.service

三、軟件環境準備

#安裝 redis

1
yum  install  redis -y

#redis經常使用命令

redis-server     redis 服務端
 
redis-cli　　　　redis 命令行客戶端
 
redis-benchmark  redis 性能測試工具
 
redis-check-aof 　　AOF文件修復工具
 
redis-check-dump  RDB文件修復工具
 
redis-sentinel 　　  Sentinel 服務端

四、初始化MySQL表結構（備註：導入表結構後，注意檢查）

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/

#設置數據庫密碼 (備註：用戶名：root ,密碼: password )

[root@ open -falcon-server open -falcon] # mysqladmin -uroot password "password"
Warning: Using a password on the command  line interface can be insecure.

#檢查導入的數據庫表

[root@ open -falcon-server open -falcon] # mysql -uroot -p
Enter password:

五、配置Go語言開發環境

#安裝go語言開發包（備註：安裝須要epel源）

1
yum  install  golang -y

#檢查版本

[root@ open -falcon-server ~] # go version
  go version go1.8.3 linux /amd64

#查看go的安裝路徑

[root@ open -falcon-server ~] # find / -name go
/etc/alternatives/go
/var/lib/alternatives/go
/usr/bin/go
/usr/lib/golang/src/cmd/go   #須要的是這個路徑
/usr/lib/golang/src/go
/usr/lib/golang/bin/go
/usr/lib/golang/pkg/linux_amd64/go

#設置環境變量GOROOT和GOPATH

export  GOROOT= /usr/lib/golang
export  GOPATH= /home

六、下載編譯好的二進制版本

https://github.com/open-falcon/falcon-plus/releases

直接下載官方編譯好的二進制版本(x86 64位平臺)。

drwxrwxr-x. 5 501 501      40 Aug 15 19:16 transfer

七、修改配置文件cfg.json

坑：

部分模塊依賴鏈接數據庫，由於若是不修改配置文件，aggregator模塊會出現沒法啓動，graph、hbs、nodata、api、alarm模塊會出現開啓不報錯可是狀態爲開啓失敗的狀況。

若是須要每一個模塊都能正常啓動，須要將上面模塊的cfg.json的數據庫信息進行修改。根據本教程的配置，須要修改配置文件所在的目錄： 

模塊 配置文件所在路徑
aggregator    /home/work/aggregator/config/cfg.json
graph /home/work/graph/config/cfg.json
hbs /home/work/hbs/config/cfg.json
nodata /home/work/nodata/config/cfg.json
api /home/work/api/config/cfg.json
alarm /home/work/alarm/config/cfg.json

1）修改aggregator的配置文件

vim /home/work/aggregator/config/cfg.json

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

 

2）修改graph的配置文件

vim /home/work/graph/config/cfg.json

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

 

3）修改hbs的配置文件

vim /home/work/hbs/config/cfg.json

 

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

 

4）修改nodata的配置文件

vim /home/work/nodata/config/cfg.json

 

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

 

5）修改api的配置文件

vim /home/work/api/config/cfg.json

 

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

 

6）修改alarm的配置文件

vim /home/work/alarm/config/cfg.json

 

mysql的root密碼爲空，則去掉「password」，若不爲空，則用root密碼替換「password」。

#For debugging , You can check $WorkDir/$moduleName/log/logs/xxx.log

至此後端部署完成。

八、其它用法

#重載配置（備註：修改vi cfg.json配置文件後，能夠用下面命令重載配置）

curl 127.0.0.1:1988 /config/reload

5、前端部署 （備註：在另一臺服務器上面操做）

一、建立工做目錄

export  HOME= /home/work
export  WORKSPACE=$HOME /open-falcon
mkdir  -p $WORKSPACE
cd  $WORKSPACE

二、克隆前端組件代碼

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

三、安裝依賴包

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

坑：

#省略下面這三步不操做（備註：因執行virtualenv ./env；安裝的pip版本爲1.4.1，再用pip安裝pip_requirements.txt文件中的軟件。都會出現報錯的狀況，致使沒法安裝成功。主要緣由就是pip版本的問題。）解決這個問題，請參考第4步
#進入目錄
cd  $WORKSPACE /dashboard/
virtualenv . /env
source  env /bin/activate #若是安裝了高版本pip，請先卸載pip uninstall pip   再按兩次y
#指定源安裝包（備註：這步若是安裝不成功，請檢查pip版本是否爲pip-9.0.1）
pip install  -r pip_requirements.txt -i

四、先安裝ez_setup.py,再安裝pip

#下載ez_setup.py
wget --no-check-certificate https: //bootstrap .pypa.io /ez_setup .py
python ez_setup.py --insecure
 
#下載pip
wget https: //pypi .python.org /packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9 .0.1. tar .gz #md5=35f01da33009719497f01a4ba69d63c9
 
#解壓並安裝
tar  xf pip-9.0.1. tar .gz
cd  pip-9.0.1
python setup.py install
cd  ..

#配置環境變量  (備註：這步不須要操做了)

#查看pip路徑
[root@prometheus dashboard] # which pip
/usr/bin/pip
 
#配置pip環境變量
[root@prometheus dashboard] # vi /etc/profile
#pip path
export  PATH= "/usr/bin/pip/bin:$PATH"
#使環境變量生效source /etc/profile
#測試是否可用
[root@prometheus dashboard] # pip

五、修改配置

#配置說明：

dashboard的配置文件爲： 'rrd/config.py' ，請根據實際狀況修改
 
## API_ADDR 表示後端api組件的地址
API_ADDR = "http://127.0.0.1:8080/api/v1"
 
## 根據實際狀況，修改PORTAL_DB_*, 默認用戶名爲root，默認密碼爲""
## 根據實際狀況，修改ALARM_DB_*, 默認用戶名爲root，默認密碼爲""

#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

 #啓動服務

#啓動服務
有兩種方法：
法一：
( env )[root@Open-Falcon-client dashboard] # bash control start
falcon-dashboard started..., pid=40853
 
法二：
( env )[root@Open-Falcon-client dashboard] # ./control start
falcon-dashboard started..., pid=40853
 
#查看日誌
( env )[root@Open-Falcon-client dashboard] # ./control tail

#訪問網站

http://192.168.1.181:8081

#關於登陸帳號的問題或參考FAQ

請自行註冊管理員用戶名和密碼

#登陸界面

六、其它用法

#以開發者模式啓動

. /env/bin/python  wsgi.py
 
open  http: //127 .0.0.1:8081 in  your browser.

#開啓8081端口 （備註：若是關閉了防火牆，則直接忽略這步）

1）防火牆添加8081端口永久開放

firewall-cmd --add-port=8081/tcp --permanent

2）從新載入防火牆配置

firewall-cmd --reload

#中止dashboard運行

1
bash  control stop

#查看dashboard運行狀態

1
bash  control status

 

6、FAQ

  • Q: open-falcon v0.2 有管理員賬號嗎？
  • A: 能夠經過dashboard自行註冊新用戶，第一個用戶名爲root的賬號會被認爲是超級管理員，超級管理員能夠設置其餘用戶爲管理員。
  • Q: open-falcon v0.2 dashboard 能夠禁止用戶本身註冊嗎？
  • A: 能夠的，在api組件的配置文件中，將signup_disable配置項修改成true，重啓api便可。
