open-falcon 分布式安装

本文主要是介绍open-falcon 分布式安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1，open-falcon 分布式安装

服务器	安装组件
192.168.0.202	单机版运行所有组件
192.168.0.196	运行组件transfer、hbs、agent

1.1 服务器192.168.0.196

• open-falcon-v0.3.x.tar.gz

# scp open-falcon-v0.3.x.tar.gz root@192.168.0.196:/home/

# mkdir open-falcon
# tar -zxvf open-falcon-v0.3.x.tar.gz -C open-falcon/

• transfer

# cp open-falcon/transfer/config/cfg.json{,.backup}
# ls open-falcon/transfer/config/
cfg.json  cfg.json.backup
# vim open-falcon/transfer/config/cfg.json

cat open-falcon/transfer/config/cfg.json | jq ."judge"
{"enabled": true,"batch": 200,"connTimeout": 1000,"callTimeout": 5000,"maxConns": 32,"maxIdle": 32,"replicas": 500,"cluster": {"judge-00": "192.168.0.202:6080"}
}

cat open-falcon/transfer/config/cfg.json | jq ."graph"
{"enabled": true,"batch": 200,"connTimeout": 1000,"callTimeout": 5000,"maxConns": 32,"maxIdle": 32,"replicas": 500,"cluster": {"graph-00": "192.168.0.202:6070"}
}

• hbs

cp open-falcon/hbs/config/cfg.json{,.backup}
ls open-falcon/hbs/config/cfg.json  cfg.json.backup

cat open-falcon/hbs/config/cfg.json
{"debug": true,"database": "root:@tcp(192.168.0.202:3306)/falcon_portal?loc=Local&parseTime=true","hosts": "","maxConns": 20,"maxIdle": 15,"listen": ":6030","trustable": [""],"http": {"enabled": true,"listen": "0.0.0.0:6031"}
}

2，运行

# ./open-falcon start agent
[falcon-agent] 33027
# ./open-falcon start hbs
[falcon-hbs] 33095
# ./open-falcon start transfer
[falcon-transfer] 33177

• hbs启动失败

# ./open-falcon checkfalcon-graph       DOWN               -falcon-hbs       DOWN               -falcon-judge       DOWN               -falcon-transfer         UP           33177falcon-nodata       DOWN               -falcon-aggregator       DOWN               -falcon-agent         UP           33027falcon-gateway       DOWN               -falcon-api       DOWN               -falcon-alarm       DOWN               -

• 查看hbs日志
  数据库连接失败

cat /root/open-falcon/hbs/logs/hbs.log
2019/11/29 15:31:25 cfg.go:79: read config file: /root/open-falcon/hbs/config/cfg.json successfully
2019/11/29 15:31:25 db.go:38: ping db fail: dial tcp 192.168.0.202:3306: connect: connection refused
2019/11/29 15:33:36 cfg.go:79: read config file: /root/open-falcon/hbs/config/cfg.json successfully
2019/11/29 15:33:36 db.go:38: ping db fail: dial tcp 192.168.0.202:3306: connect: connection refused

3，登陆安装数据库的节点192.168.0.202

mysql> select Host,User,authentication_string,plugin from user;
+-----------+------------------+-------------------------------------------+-----------------------+
| Host      | User             | authentication_string                     | plugin                |
+-----------+------------------+-------------------------------------------+-----------------------+
| localhost | root             |                                           | mysql_native_password |
| localhost | mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password |
| localhost | mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password |
| localhost | debian-sys-maint | *FA4B1F47B8478379F08A57DAD145CE48A2B53E47 | mysql_native_password |
+-----------+------------------+-------------------------------------------+-----------------------+
4 rows in set (0.00 sec)

• 配置mysql数据库root远程登陆

mysql> update user set Host='%' where User='root';
mysql> select Host,User,authentication_string,plugin from user;
+-----------+------------------+-------------------------------------------+-----------------------+
| Host      | User             | authentication_string                     | plugin                |
+-----------+------------------+-------------------------------------------+-----------------------+
| %         | root             |                                           | mysql_native_password |
mysql> grant all on *.* to 'root'@'%';
Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.05 sec)

grep -irn 127.0.0.1 ./
./mysql.conf.d/mysqld.cnf:43:bind-address		= 127.0.0.1

• 注释bind-address

vim /etc/mysql/mysql.conf.d/mysqld.cnf
# bind-address          = 127.0.0.1

• 重启mysql

systemctl restart mysql.service

4，重启启动hbs 192.168.0.196

# ./open-falcon start hbs
[falcon-hbs] 48105
# ./open-falcon checkfalcon-graph       DOWN               -falcon-hbs         UP           48105falcon-judge       DOWN               -falcon-transfer         UP           33177falcon-nodata       DOWN               -falcon-aggregator       DOWN               -falcon-agent         UP           33027falcon-gateway       DOWN               -falcon-api       DOWN               -falcon-alarm       DOWN               -

• 服务器添加成功
  

6，其它分布式节点安装

scp -r root@192.168.0.196:/root/open-falcon/ .

./open-falcon check

./open-falcon start hbs && ./open-falcon start agent && ./open-falcon start transfer
