使用ambari安装dolphinscheduler服务

ambari服务集成dolphinscheduler服务

1.将需要集成到ambari的服务安装包放到该目录下

/var/lib/ambari-server/resources/stacks/HDP/3.1/services

2.重启ambari-server服务

sudo ambari-server restart

继承完之后在ambari页面上进行服务安装

1.添加服务选择dolphinscheduler

2.dolphinscheduler服务配置

这个选择使用mysql数据作为dolphinscheduler服务的元数据库

3.服务选择进行安装

选择两个DS-master，至少两个DS-ALTERS,DS-APIS,其余节点都部署DS-worker节点

4.如果在安装dolphinscheduler之前做了namenode-ha则可能会报'hue-desktop-ini'相关报错，则需要对params.py脚本进行修改

脚本位置


/var/lib/ambari-server/resources/stacks/HDP/3.3/services/DOLPHINSCHEDULER/package/scripts/params.py

修改内容
#hdfs_httpfs_host = config['configurations']['hue-desktop-ini']['hdfs_httpfs_host']
 hdfs_httpfs_host = "dfs_ha_enabled"

注释#hdfs_httpfs_host = config['configurations']['hue-desktop-ini']['hdfs_httpfs_host']
给hdfs_httpfs_host 任意赋值一个参数让下边的webhdfs_url直接取第一个namenode_hosts[0]

修改完之后保存重启ambari-server服务重新安装dolphinscheduler

5.拷贝mysql驱动到所有节点libs目录下

cp /tmp/mysql-connector-j-8.0.33.jar /usr/hdp/current/dolphinscheduler/alert-server/libs/
cp /tmp/mysql-connector-j-8.0.33.jar /usr/hdp/current/dolphinscheduler/api-server/libs/
cp /tmp/mysql-connector-j-8.0.33.jar /usr/hdp/current/dolphinscheduler/master-server/libs/
cp /tmp/mysql-connector-j-8.0.33.jar /usr/hdp/current/dolphinscheduler/worker-server/libs/
cp /tmp/mysql-connector-j-8.0.33.jar /usr/hdp/3.3.1.0-004/dolphinscheduler/tools/libs/

6.因为第二步配置的用户为hdfs用户所以需要将所有服务所属组改为hdfs

/var/log/dolphinscheduler
/usr/hdp/3.3.1.0-004/dolphinscheduler
/etc/dolphinscheduler/

chown -R hdfs:hdfs dolphinscheduler

sdo ln -s /usr/hdp/3.1.4.0-315/dolphinscheduler dolphinscheduler

修改完之后ambari管理平台上启动dolphinscheduler，启动过程中元数据会自动初始化建表
