小米开源监控平台Open-Falcon安装部署

一、系统环境准备

目前我这里原文链接：https://www.dqzboy.com使用单机版进行部署，也可以前后端进行分离，前端，后端，数据库分别在不同的服务器上进行部署搭建

[root@localhost ~]# hostnamectl set-hostname open-falcon

####备份系统BASE源
[root@open-falcon ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

####阿里源####
[root@open-falcon ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

####epel源####
[root@open-falcon ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

####更新缓存####
[root@open-falcon ~]# yum clean all
[root@open-falcon ~]# yum makecache
[root@open-falcon ~]# yum repolist

[root@localhost ~]# yum -y install vim net-tools lrzsz ntp wget get curl rsync git

[root@open-falcon ~]# systemctl start ntpd
[root@open-falcon ~]# systemctl enable ntpd
[root@open-falcon ~]# systemctl status ntpd
[root@open-falcon ~]# date	    ##检查时间

[root@open-falcon ~]# systemctl stop firewalld
[root@open-falcon ~]# systemctl disable firewalld
[root@open-falcon ~]# setenforce 0
[root@open-falcon ~]# sed -ri 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

二、软件环境准备

• 注意：官方yum和阿里yum都没有go的安装包，只能通过fedora的epel仓库来安装

#安装
[root@open-falcon ~]# yum install -y epel-release
[root@open-falcon ~]# yum install golang -y

#检查
[root@open-falcon ~]# go version
go version go1.11.5 linux/amd64

#部署新版redis
[root@open-falcon ~]# yum install -y http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
#安装
[root@open-falcon ~]# yum --enablerepo=remi install redis

#启动
[root@open-falcon ~]# systemctl start redis

#开机自启
[root@open-falcon ~]# systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.

#检查状态
[root@open-falcon ~]# systemctl status redis

[root@open-falcon ~]# wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
[root@open-falcon ~]# rpm -ivh mysql57-community-release-el7-11.noarch.rpm

#查看 mysql server
[root@open-falcon ~]# yum repolist enabled | grep "mysql.*-community.*"
[root@open-falcon ~]# yum repolist all | grep mysql

#安装
[root@open-falcon ~]# yum install mysql-community-server

#启动数据库
[root@open-falcon ~]# systemctl start mysqld.service
[root@open-falcon ~]# systemctl enable mysqld.service
[root@open-falcon ~]# systemctl status mysqld.service

• MySQL5.7.6 之后会在启动 mysql 进程的时候生成一个用户密码，首次登陆需要这个密码才行。密码保存在 mysql 进程的日志里，即(/var/log/mysqld.log)

#查看登陆密码
[root@open-falcon ~]#  cat /var/log/mysqld.log | grep 'password'

#登陆
[root@open-falcon ~]#  mysql -uroot -p

• 修改ROOT密码文章来源(Source)：浅时光博客

mysql> set global validate_password_policy=0;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123';

三、部署open-falcon

[root@open-falcon ~]#  cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git
[root@open-falcon ~]# cd /tmp/falcon-plus/scripts/mysql/db_schema/
[root@open-falcon ~]# mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
[root@open-falcon ~]# mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
[root@open-falcon ~]# mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql
[root@open-falcon ~]# mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql
[root@open-falcon ~]# mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql
[root@open-falcon ~]# rm -rf /tmp/falcon-plus/

[root@open-falcon ~]# vim /etc/profile
export FALCON_HOME=/usr/local/open-falcon

[root@open-falcon ~]# source /etc/profile
[root@open-falcon ~]# mkdir -p $FALCON_HOME

[root@open-falcon ~]# wget https://github.com/open-falcon/falcon-plus/releases/download/v0.3/open-falcon-v0.3.tar.gz

[root@open-falcon ~]# tar -zxvf open-falcon-v0.3.tar.gz -C $FALCON_HOME
[root@open-falcon ~]# cd $FALCON_HOME

[root@open-falcon ~]# vim /usr/local/open-falcon/aggregator/config/cfg.json

[root@open-falcon open-falcon]# yum install -y openldap-devel

Jinja2>=2.10.1
Werkzeug==0.15.3

##注意：3.0版本修改Werkzeug==0.15.4  才可以启动
[root@open-falcon dashboard]# vim pip_requirements.txt 
Werkzeug==0.15.4

[root@open-falcon dashboard]# virtualenv ./env
[root@open-falcon dashboard]# ./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’，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””
