详解监控open-falcon部署,避免踩坑

详解open-falcon部署,避免踩坑

环境是centos系统

1.配置gopath环境变量

1.配置go环境变量
	1.1.vim /etc/profile 将下面的配置添加进去
	    export GOROOT=/usr/local/go         
        export GOPATH=/usr/local/gocode 
        export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
    
    1.2.并激活环境变量 source /etc/profile


注意：
  由于open-falcon当前版本还是用go vendor包管理
  但是现在的很多环境基本都用go mod包管理工具替换了
  先查看当前环境go env, 如果使用的是go mod格式，就先将其关闭
  go env -w GO111MODULE="off"  也可以  export GO111MODULE=off

2.安装redis

1.wget下载 （指定版本可以去redis官网看下有哪些版本）
	wget https://download.redis.io/releases/redis-6.2.6.tar.gz

2.解压
	mv redis-6.2.6.tar.gz /opt
	tar -xzvf redis-6.2.6.tar.gz

3.安装
	3.1 建立软链接
	    ln -s redis-6.2.6.tar.gz redis (测试环境不需要这一步)
	    建立一个redis目录的软链接 指向redis-6.2.6.tar.gz，不把redis目录固定指定的版本上 有利于redis未来的升级

	3.2 编译
	    1. cd redis-6.2.6/
	    2. make (编译 编译之前确保操作系统已经安装gcc)

    3.3 安装执行文件
        1.make install 
	    解释：安装redis相关运行文件到/usr/local/bin下 这样可以保证在任何文件下都可以执行redis-cli 
        否则只能在/opt/redis-6.2.6/src目录下执行
      
    3.4 redis后台启动
      1. cd /opt/redis-6.2.6/
      2. vim redis.conf
         更改daemonize yes
      3.redis-server /opt/redis-6.2.6/redis.conf 进入后台运行

open-falcon提供的安装语句yum install -y redis

3.安装mysql

1.强制卸载mariadb
  rpm -e --nodeps mariadb-libs-5.5.65-1.el7.x86_64

2.查询
  pm -qa|grep mariadb 没结果就是删除成功


3.官网下载页面 https://dev.mysql.com/downloads/repo/yum/
    找到centos对应的版本
    Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package		6.9K	Download
	(mysql80-community-release-el7-4.noarch.rpm)	MD5: 8b55d5fc443660fab90f9dc328a4d9ad
	
4.下载对应的版本
    wget -i -c http://dev.mysql.com/get/mysql80-community-release-el7-4.noarch.rpm
	

5.安装刚下载的rpm包
	yum localinstall mysql80-community-release-el7-4.noarch.rpm
   （网上好像还有这个安装方式 rpm -ivh mysql80-community-release-el7-4.noarch.rpm）
   
	安装这个包后，会获得两个mysql的yum-repo源：
	/etc/yum.repos.d/mysql-community.repo
	/etc/yum.repos.d/mysql-community-source.repo

6.安装mysql服务并启动
	yum install mysql-community-server
	systemctl status mysqld.service
	systemctl start mysqld.service

7.查询MySQL的临时密码
	grep 'temporary password' /var/log/mysqld.log （将临时密码复制下来）
	mysql -uroot -p 输入刚才复制的临时密码
	
	更改数据库密码
	ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';  (新密码要数字字母，否则会报错)
	
	如果需要简单的密码设置
	如果5.6版本也就是旧版本执行下面的操作
	mysql> set global validate_password_policy=0;
		   Query OK, 0 rows affected (0.00 sec)
	mysql> set global validate_password_length=1;
			Query OK, 0 rows affected (0.00 sec)

    ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
    
    
    如果是8.0版本 新版本
    需先设置一个符合的密码
	ALTER USER 'root'@'localhost' IDENTIFIED BY 'Root_root123*';
	在执行下面的操作设置新的简单的密码
	mysql> set global validate_password.policy=0;
		   Query OK, 0 rows affected (0.00 sec)
    mysql>  set global validate_password.length=1;
			Query OK, 0 rows affected (0.00 sec)
		   
	ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
	
open-falcon提供的安装语句yum install -y mysql-server 

4.下载open-falcon

1.下载open-falcon
  mkdir -p $GOPATH/src/github.com/open-falcon
  cd $GOPATH/src/github.com/open-falcon
  git clone https://github.com/open-falcon/falcon-plus.git
  
2.导入初始化mysql数据库/表的sql语句
	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

5.部署open-falcon

第一种部署方式：
1.切换目录
cd $GOPATH/src/github.com/open-falcon/falcon-plus/

2.vi config/confgen.sh

confs=(
    '%%AGENT_HTTP%%=0.0.0.0:1988'
    '%%AGGREGATOR_HTTP%%=0.0.0.0:6055'
    '%%GRAPH_HTTP%%=0.0.0.0:6071'
    '%%GRAPH_RPC%%=0.0.0.0:6070'
    '%%HBS_HTTP%%=0.0.0.0:6031'
    '%%HBS_RPC%%=0.0.0.0:6030'
    '%%JUDGE_HTTP%%=0.0.0.0:6081'
    '%%JUDGE_RPC%%=0.0.0.0:6080'
    '%%NODATA_HTTP%%=0.0.0.0:6090'
    '%%TRANSFER_HTTP%%=0.0.0.0:6060'
    '%%TRANSFER_RPC%%=0.0.0.0:8433'
    '%%REDIS%%=127.0.0.1:6379'
    '%%MYSQL%%=user:password@tcp(127.0.0.1:3306)'   //将这里的数据库账户密码更换成自己机器数据库的配置 这样就会更新所有配置
    '%%PLUS_API_DEFAULT_TOKEN%%=default-token-used-in-server-side'
    '%%PLUS_API_HTTP%%=0.0.0.0:8080'
 )
 
3.打包
	注: 由于涉及数据库驱动 需要cd $GOPATH/src/ 然后go get -u github.com/go-sql-driver/mysql
	下载mysql驱动

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

	# make specified module
  	make agent

	# pack all modules
  	make pack

    生成安装包
    open-falcon-v0.3.x.tar.gz

第二种部署方式：
1.可以直接取官网安装包
  https://github.com/open-falcon/falcon-plus/releases
  
  解压
  mkdir -p /opt/open-falcon
  tar -xzvf open-falcon-v0.3.x.tar.gz -C /opt/open-falcon
  
  切换目录
  cd /opt/open-falcon
  
  当前目录将配置文件的数据库密码更新
  grep -Ilr 3306  ./ | xargs -n1 -- sed -i 's/root:/real_user:real_password/g'   
  

2.启动open-falcon
 ./open-falcon start

 # check modules status
 ./open-falcon check

6.open-falcon前端环境创建

1.进入刚建立的falcon目录
    cd /opt/open-falcon

2.克隆项目
    git clone https://github.com/open-falcon/dashboard.git

3.进入目录 cd dashboard;

    yum install -y python-virtualenv
	yum install -y python-devel
	yum install -y openldap-devel
	yum install -y mysql-devel
	yum groupinstall "Development tools"
  
4. python安装需要区分环境
    4.1. 官方给的创建流程是下面这样的
	    virtualenv ./env                              //创建一个单独的虚拟环境 
	    ./env/bin/pip install -r pip_requirements.txt

	
    4.2.我的机器有两个python环境 安装dashboard用python2.7虚拟环境
 		1.1.如果要创建python2的环境的话，命令为
		virtualenv -p /usr/bin/python2.7 ./env      
	    ./env/bin/pip install -r pip_requirements.txt
	
		1.2.如果要创建python3的环境话，命令为
		virtualenv -p /usr/bin/python3.6 ./env
        ./env/bin/pip install -r pip_requirements.txt
	 
	   在单独的虚拟环境执行pip命令（./env/bin/pip -V可以查看自己版本）
   
    4.3 如果安装mysql-python的时候一直报错
        没找到mysql.h文件，可以按照下面的方式解决
    

注意：安装mysql-python的问题

sudo vim /usr/include/my_config.h

5.启动前端

1.还是在dashboard这个目录，更改相应的配置文件
	vi wsgi.py
	
	if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8088, debug=False) //找一个空闲的端口 我选择的机器的8088端口

2.vi gunicorn.conf
	workers = 4
	bind = ':8088' //和刚才配置的wsgi.py配置相同
	proc_name = 'falcon-dashboard-opensource'
	pidfile = '/tmp/falcon-dashboard-opensource.pid'
	limit_request_field_size = 0
	limit_request_line = 0
	
	
3.vi rrd/config.py
# Falcon+ API

API_ADDR = os.environ.get("API_ADDR","http://127.0.0.1:8080/api/v1") 
//这里的8080要和 WorkDir下的api/config/cfg.json下的 "web_port": "0.0.0.0:8080"端口一致 也就是open-falcon的后端接口相同

API_USER = os.environ.get("API_USER","admin")
API_PASS = os.environ.get("API_PASS","password")

# portal database
# TODO: read from api instead of db
PORTAL_DB_HOST = os.environ.get("PORTAL_DB_HOST","127.0.0.1")
PORTAL_DB_PORT = int(os.environ.get("PORTAL_DB_PORT",3306))
PORTAL_DB_USER = os.environ.get("PORTAL_DB_USER","root")
PORTAL_DB_PASS = os.environ.get("PORTAL_DB_PASS","password") //数据库密码配置好
PORTAL_DB_NAME = os.environ.get("PORTAL_DB_NAME","falcon_portal")

# alarm database
# TODO: read from api instead of db
ALARM_DB_HOST = os.environ.get("ALARM_DB_HOST","127.0.0.1")
ALARM_DB_PORT = int(os.environ.get("ALARM_DB_PORT",3306))
ALARM_DB_USER = os.environ.get("ALARM_DB_USER","root")
ALARM_DB_PASS = os.environ.get("ALARM_DB_PASS","password")   //数据库密码配置好
ALARM_DB_NAME = os.environ.get("ALARM_DB_NAME","alarms")

bash control start
