一.配置
FE: 192.168.28.131 10G(內存) 100G
BE1: 192.168.28.128 20G(內存) 200G
BE2: 192.168.28.129 20G(內存) 200G
BE3: 192.168.28.130 20G(內存) 200G
Ⅰ).BE
vi be.conf
# INFO,WARNING,ERROR,FATAL
sys_log_level=INFO
# ports for admin,web,heartbeat service
be_port=9060
be_rpc_port=9070
webserver_port=8040
heartbeat_service_port=9050
brpc_port=8060
# Choose one if there are more than one ip except loopback address
# 24為網關
priority_networks=hostname/24 (hostname修改對應be的ip)
# storage_root_path=/home/disk1/palo.HDD,50;/home/disk2/palo.SSD,1;/home/disk2/palo
# 目錄需手動創建
storage_root_path=/data/opt/be/palo
Ⅱ).FE
vi fe.conf
# INFO,WARNING,ERROR,FATAL
sys_log_level=INFO
# store metadata,create it if it is not exist
meta_dir=${DORIS_HOME}/palo-meta
http_port=8030
rpc_port=9020
query_port=9030
edit_log_port=9010
# Choose one if there are more than one ip except loopback address
# 24為網關
priority_networks=hostname/24(hostname修改對應fe的ip)
Ⅲ).網絡通信端口
二.服務命令
Ⅰ).啟停
a).啟動服務FE和BE
sh /data/opt/fe/bin/start_fe.sh --daemon
sh /data/opt/be/bin/start_be.sh --daemon
b).停止服務
sh /data/opt/fe/bin/stop_fe.sh
sh /data/opt/be/bin/stop_be.sh
Ⅱ).驗證
URL: http://hostname:8030/system 查看FE節點: http://hostname:8030/system?path=//frontends
三.業務命令
Ⅰ).連接FE
mysql -h 192.168.0.11 -P 9030 -uroot -p123456
Ⅱ).創建數據庫
create database doris;
Ⅲ).創建用戶
create user 'doris' identified by '1234';
Ⅳ).賦權
grant all on doris to doris;
Ⅴ).添加BE
ALTER SYSTEM ADD BACKEND "hostname:9050";
Ⅵ).查看BE狀態
SHOW PROC '/backends';
使用 mysql-client 連接到 FE，並執行
SHOW PROC '/backends';
查看 BE 運行情況。如一切正常，isAlive 列應為 true
Ⅶ).刪除BE
ALTER SYSTEM DROPP BACKEND "hostname:9050";
Ⅷ).添加FE
ALTER SYSTEM ADD FOLLOWER "hostname:9050";
Ⅸ).查看FE狀態
SHOW PROC '/frontends';
Ⅹ).刪除FE
ALTER SYSTEM DROPP FOLLOWER "hostname:9050";
Ⅺ).創建表
CREATE TABLE doris.table2
(
event_day DATE,
siteid INT DEFAULT '10',
citycode SMALLINT,
username VARCHAR(32) DEFAULT '',
pv BIGINT SUM DEFAULT '0'
)
AGGREGATE KEY(event_day,citycode,username)
PARTITION BY RANGE(event_day)
(
PARTITION p1 VALUES LESS THAN ('2019-06-30'),
PARTITION p1 VALUES LESS THAN ('2019-07-31'),
PARTITION p1 VALUES LESS THAN ('2019-08-31')
)
DISTRIBUTED BY HASH(siteid) BUCKETS 10
PROPERTIES("replication_num"="1")
Ⅻ).導入數據
1.database: doris 2.tablename: table2 3.label: 每個批次不可重複 4.column_separator: 數據文件中字段之間特殊符號分割(|-%7c, ,-%2c, t-%09, x01-%01)
分割符
對應值
豎線
%7c
,
%2c
\\t
%09
\\\\x01
%01
curl --location-trusted -u db_user -T path/filename.txt http://hostname/8030/api/doris/table2/_load?label=100\\&column_separator=%7c
curl --location-trusted -u root:root -T aaa http://192.168.1.5:8030/api/example_db/NewTable2/_load?label=table2_20190901\\&column_separator=%2c -V
XIII).創建MySQL引擎表
CREATE TABLE IF NOT EXISTES doris.table_name
(
'agent_id' INT NOT NULL,
'accept_time' DATETIME NOT NULL,
'signature' VARCHAR(770) NOT NULL,
'bad_app_count' BIGINT,
'total_count' BIGINT,
'version' INT DEFAULT "0",
'method_type' VARCHAR(20)
)
ENGINE=mysql
PROPERTIES
(
"host"="db_hostname",
"port"="3306",
"user"="db_user",
"password"="password",
"database"="database",
"table"="table_name"
)
