Ubuntu下安装open-falcon-v0.2.1

tonglin0325

在Ubuntu下安装open-falcon和Centos下安装的方法有点区别，因为Ubuntu使用的包管理器是apt-get，而Centos下使用的是Yum，建议不要再Ubuntu下使用yum

建议自己下载源码打包二进制包来安装，因为官方给出的二进制包应该是再centos下打包的，再Ubuntu下运行可能会出现问题

1.安装Go，首先去官网下载，需要fq

1
2
https://golang.org

顺便安装Goland，注册服务器 http://idea.youbbs.org

2.在/etc/profile中添加，后source /etc/profile

5
#Go
export GOROOT=/home/lintong/software/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
export GOPATH=/home/lintong/software/gopath

验证是否安装成功

1
2
3
go version
go version go1.10.2 linux/amd64

接下来参考

Ubuntu 16.04 部署 open-falcon

运维监控系统之Open-Falcon

Open-falcon的官方README

 3.安装redis和mysql

1
2
3
sudo apt-get install redis-server
sudo apt-get install mysql-server

 确保两个服务已经启动

1
2
systemctl status mysql redis-server

 

4.下载open-falcon源码，地址

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

 初始化MySQL表结构

mkdir -p $GOPATH/src/github.com/open-falcon
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

  1. 编译二进制包

cd $GOPATH/src/github.com/open-falcon/falcon-plus/
# make all modules
make all
# make specified module
make agent
# pack all modules
make pack

 打包成功，在目录下多了文件open-falcon-v0.2.1.tar.gz

go build -ldflags "-X main.GitCommit=`git rev-parse --short HEAD` -X main.Version=0.2.1" -o open-falcon
tar -C out -zcf open-falcon-v0.2.1.tar.gz .

 6.解压到安装目录

1
2
3
mkdir ~/software/open-falcon-v0.2.1
tar -zxvf open-falcon-v0.2.1.tar.gz -C ~/software/open-falcon-v0.2.1/

 7.安装open-falcon的前端框架dashboard

1
2
3
cd ~/software/open-falcon-v0.2.1
git clone https://github.com/open-falcon/dashboard.git

8.修改数据库密码，因为open-falcon需要操作数据库，这一步是官方教程中没有提到的

如果没有进行修改的话，在open-falcon-v0.2.1目录下使用./open-falcon start命令进行启动之后，使用./open-falcon check检查组件的状态，有些使用mysql的组件的状态是down

下面列出了使用mysql的组件，总共有6个：aggregator，graph、hbs、nodata、api、alarm模块

需要对这些组件的配置文件进行修改：

1
2
vim ~/software/open-falcon-v0.2.1/aggregator/config/cfg.json

修改成

 

其他配置文件的修改方式类似

1
2
vim graph/config/cfg.json

1
2
vim hbs/config/cfg.json

1
2
vim nodata/config/cfg.json

 

1
2
vim api/config/cfg.json # 5处全部修改

1
2
vim alarm/config/cfg.json

接下来需要在前端组件中，配置数据库密码

1
2
3
cd ~/software/open-falcon-v0.2.1/dashboard/rrd
vim config.py

 

9.安装Python的依赖，在Ubuntu下不要使用Yum

1
2
3
4
5
sudo apt-get install python-pip python-virtualenv
sudo apt-get install python-dev
sudo apt-get install ldap-utils
sudo apt-get install libmysqld-dev

10.安装virtualenv的运行环境，在服务器上是不建议直接pip安装的，因为Python包的冲突可能会影响到别人的服务

1
2
3
4
~/software/open-falcon-v0.2.1/dashboard
virtualenv ./env
./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple

 如果出现 Failed building wheel for python-ldap 的问题
请参考      Installing python-ldap in Ubuntu 

1
2
3
4
5
6
sudo apt-get install python-dev
sudo apt-get install libldap2-dev
sudo apt-get install libsasl2-dev
# 然后再
./env/bin/pip install python-ldap

请确保每个Python包都安装到位，成功如下

11.启动open-falcon的后端，注意check的时候，每个组件需要都是up状态，down状态说明出了问题

 以开发者模式启动前端组件
