小米监控 open-falcon部署

具体详情请参考官方文档  http://book.open-falcon.org/zh_0_2/quick_install/    centos6.8    建议centos7系统  否则后面按照官方文档来是有很多问题的   需要解决Python依赖问题    Python2.7 版本以上，由于centos6.8  pyhton默认版本是 2.6

环境准备

安装redis

yum install -y redis

安装mysql

yum install -y mysql-server  #可以选择源码编译安装

注意，请确保redis和MySQL已启动。

初始化MySQL表结构

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/

下载版本包

https://github.com/open-falcon/falcon-plus/releases/download/v0.2.0/open-falcon-v0.2.0.tar.gz

启动后端

配置go语言开发环境

yum install golang -y  #需要epel源

 go version

go version go1.9.4 linux/amd64

[root@ db_schema]# find / -name go

/etc/alternatives/go

/var/lib/alternatives/go

/usr/bin/go

/usr/lib/golang/pkg/linux_amd64/cmd/go   

/usr/lib/golang/pkg/linux_amd64/go

/usr/lib/golang/bin/go

/usr/lib/golang/src/cmd/go   #需要这个路劲

/usr/lib/golang/src/go

export GOROOT=/usr/lib/golang
export GOPATH=/usr/local
export FALCON_HOME=/usr/local
export WORKSPACE=$FALCON_HOME/open-falcon

创建工作目录

创建工作目录

export FALCON_HOME=/usr/local

export WORKSPACE=$FALCON_HOME/open-falcon

mkdir -p $WORKSPACE

tar xf open-falcon-v0.2.1.tar.gz -C $WORKSPACE

首先确认配置文件中数据库账号密码与实际相同，否则需要修改配置文件。

cd $WORKSPACE
grep -Ilr 3306  ./ | xargs -n1 -- sed -i 's/root:password/real_user:real_password/g'

如

[root@sz_fy_nginx_haproxy_11_147 open-falcon]# cat aggregator/config/cfg.json 
{
    "debug": true,
    "http": {
        "enabled": true,
        "listen": "0.0.0.0:6055"
    },
    "database": {
        "addr": "root:@tcp(127.0.0.1:3306)/falcon_portal?loc=Local&parseTime=true",  #默认账户是root   密码为空   修改成对应的账户密码  并在mysql里面授权
        "idle": 10,
        "ids": [1, -1],
        "interval": 55
    },
    "api": {
        "connect_timeout": 500,
        "request_timeout": 2000,
        "plus_api": "http://127.0.0.1:8099",
        "plus_api_token": "default-token-used-in-server-side",
        "push_api": "http://127.0.0.1:1988/v1/push"
    }
}

cd $WORKSPACE
./open-falcon start

# 检查所有模块的启动状况
./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

./open-falcon check

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

安装前端，这里选择在一台机器上面部署

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

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"


cd $WORKSPACE/dashboard/
virtualenv ./env

./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple   #centos6上面执行是通不过的 ，解决办法  升级Python2.7 （暂未验证，不建议随便升级系统Python版本，会影响系统稳定性）   或者如下操作

解决

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py

 python ez_setup.py --insecure

wget https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz

[root@open-falcon-server dashboard]# tar xf pip-9.0.1.tar.gz

[root@open-falcon-server dashboard]# cd pip-9.0.1

[root@open-falcon-server pip-9.0.1]# python setup.py install

[root@open-falcon-server dashboard]# pip install -r pip_requirements.txt

  Running setup.py install for python-dateutil ... done

修改配置

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""

以开发者模式启动

./env/bin/python wsgi.py

open http://127.0.0.1:8081 in your browser.

在生产环境启动

bash control start

open http://127.0.0.1:8081 in your browser.

停止dashboard运行

bash control stop

查看日志

bash control tail

访问测试  ip:8081

dashbord没有默认创建任何账号包括管理账号，需要你通过页面进行注册账号。
想拥有管理全局的超级管理员账号，需要手动注册用户名为root的账号（第一个帐号名称为root的用户会被自动设置为超级管理员）。
超级管理员可以给普通用户分配权限管理。
