一、单机安装Open-Falcon

下载地址:https://github.com/open-falcon/falcon-plus/releases

官方文档:http://book.open-falcon.org/zh_0_2/

[准备环境]()

[安装epel源]()

[root@localhost ~]# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@localhost ~]# rpm -ivh epel-release-latest-7.noarch.rpm

[安装redis]()

[root@localhost ~]# yum -y install redis
[root@localhost ~]# systemctl start redis
[root@localhost ~]# systemctl enable redis

[安装mariadb]()

[root@localhost ~]# yum -y install mariadb-server mariadb-devel
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# mysqladmin -uroot password 123456

[初始化MySQL表结构]()

[root@localhost ~]# yum -y install git
[root@localhost ~]# git clone https://github.com/open-falcon/falcon-plus.git
[root@localhost ~]# cd falcon-plus/scripts/mysql/db_schema/
[root@localhost db_schema]# mysql -h 127.0.0.1 -uroot -p123456 < 1_uic-db-schema.sql
[root@localhost db_schema]# mysql -h 127.0.0.1 -uroot -p123456 < 2_portal-db-schema.sql
[root@localhost db_schema]# mysql -h 127.0.0.1 -uroot -p123456 < 3_dashboard-db-schema.sql
[root@localhost db_schema]# mysql -h 127.0.0.1 -uroot -p123456 < 4_graph-db-schema.sql
[root@localhost db_schema]# mysql -h 127.0.0.1 -uroot -p123456 < 5_alarms-db-schema.sql
[root@localhost db_schema]# cd 
[root@localhost ~]# rm -rf falcon-plus/

如果是0.1.0升级到0.2.0则只需执行

mysql -h 127.0.0.1 -uroot -p123456 < 5_alarms-db-schema.sql

[Transfer]()

transfer是数据转发服务。它接收agent上报的数据,然后按照哈希规则进行数据分片、并将分片后的数据分别push给graph&judge等组件。

[API]()

<strong>api</strong>`组件,提供统一的restAPI操作接口。比如:api组件接收查询请求,根据一致性哈希算法去相应的graph实例查询不同metric的数据,然后汇总拿到的数据,最后统一返回给用户。`

[管理方式]()

# 启动服务
./open-falcon start api

# 停止服务
./open-falcon stop api

# 查看日志
./open-falcon monitor api

[Graph]()

graph是存储绘图数据的组件。graph组件 接收transfer组件推送上来的监控数据,同时处理api组件的查询请求、返回绘图数据。

[root@master open-falcon]# cat /usr/local/open-falcon/graph/config/cfg.json
{
    "debug": false,        #是否开启debug日志
    "http": {
        "enabled": true,    #表示是否开启该http端口,该端口为控制端口,主要用来对graph发送控制命令、统计命令、debug命令
        "listen": "0.0.0.0:6071"    #表示监听的http端口
    },
    "rpc": {
        "enabled": true,    #表示是否开启该rpc端口,该端口为数据接收端口
        "listen": "0.0.0.0:6070"    #表示监听的rpc端口
    },
    "rrd": {
        "storage": "./data/6070"    #历史数据的文件存储路径(如有必要,请修改为合适的路)
    },
    "db": {
        "dsn": "root:123456@tcp(127.0.0.1:3306)/graph?loc=Local&parseTime=true",    #MySQL的连接信息,默认用户名是root,密码为空,host为127.0.0.1,database为graph(如有必要,请修改)
        "maxIdle": 4    #MySQL连接池配置,连接池允许的最大连接数,保持默认即可
    },
    "callTimeout": 5000,    #RPC调用超时时间,单位m
    "migrate": {    #扩容graph时历史数据自动迁移
            "enabled": false,    #true or false, 表示graph是否处于数据迁移状态
            "concurrency": 2,    #数据迁移时的并发连接数,建议保持默认
            "replicas": 500,    #这是一致性hash算法需要的节点副本数量,建议不要变更,保持默认即可(必须和transfer的配置中保持一致)
            "cluster": {    #未扩容前老的graph实例列表
                    "graph-00" : "127.0.0.1:6070"
            }
    }
}

[管理方式]()

# 启动服务
./open-falcon start graph

# 停止服务
./open-falcon stop graph

# 查看日志
./open-falcon monitor graph

[开启后端]()

[root@master open-falcon]# ./open-falcon start transfer hbs api graph judge
[falcon-transfer] 74054
[falcon-hbs] 74061
[falcon-api] 74069

<strong>如需全部服务可以</strong>

[root@master open-falcon]# ./open-falcon start
