Dolphinscheduler1.3.8集群部署 _Scheduler

时人不识凌云木，直待凌云始道高。这篇文章主要讲述Dolphinscheduler1.3.8集群部署相关的知识，希望能为你提供帮助。
1. 集群节点规划及说明

主机	部署服务	说明
172.16.53.179	masterserver,alertserver,zookeeper,mysql	数据库也在该主机
172.16.53.180	zookeeper	zk
172.16.53.181	apiserver,zookeeper	web服务端口:12345
172.16.53.182	masterserver
172.16.53.183	workserver
172.16.53.189	workserver
172.16.53.193	workserver

2. 安装说明安装包地址：https://dlcdn.apache.org/dolphinscheduler/1.3.8/apache-dolphinscheduler-1.3.8-bin.tar.gz

新建dolphinscheduler用户(集群所有主机都执行)
useradd dolphinscheduler
创建部署目录，并赋予dolphinscheduler用户操作权限(集群所有主机都执行)
mkdir -p /opt/dolphinscheduler chown -R dolphinscheduler:dolphinscheduler /opt/dolphinscheduler
配置 sudo 免密(集群所有主机都执行)
echo \'dolphinschedulerALL=(ALL)NOPASSWD: NOPASSWD: ALL\' > > /etc/sudoers
配置dolphinscheduler用户免密
注：172.16.53.179到所有主机的免密登陆
172.16.53.179主机执行如下：
ssh-keygen -t rsa -P \'\' -f ~/.ssh/id_rsa cat ~/.ssh/id_rsa.pub > > ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys

将172.16.53.179主机的公钥拷贝至其它主机的~/.ssh/authorized_keys下
配置hosts映射(集群所有主机都执行)
所有主机的/etc/hosts下配置
172.16.53.179 node01 172.16.53.180 node02 172.16.53.181 node03 172.16.53.182 node04 172.16.53.183 node05 172.16.53.189 node06 172.16.53.193 node07
创建运行任务目录，并赋予777权限(集群所有主机都执行)
mkdir -p /tmp/dolphinscheduler chmod -R 777 /tmp/dolphinscheduler
创建hdfs资源中心目录(任一台主机)
su - hdfs hdfs dfs -mkdir /dolphinscheduler hdfs dfs -chown -R 777 /dolphinscheduler
下载并解压apache-dolphinscheduler-1.3.8-bin.tar.gz
172.16.53.179主机dolphinscheduler用户下执行：
cd /opt/dolphinscheduler wget https://dlcdn.apache.org/dolphinscheduler/1.3.8/apache-dolphinscheduler-1.3.8-bin.tar.gz tar -zxvf apache-dolphinscheduler-1.3.8-bin.tar.gz -C /opt/dolphinscheduler mv apache-dolphinscheduler-1.3.8-bindolphinschedulerinstall

9.所有节点安装jdk(root用户下执行)并配置环境变量如下：
vim /etc/profile.d/jdk.sh

java_HOME=/usr/java/jdk1.8.0_181-cloudera JRE_HOME=/usr/java/jdk1.8.0_181-cloudera/jre PATH=$PATH:$JAVA_HOME/bin export JAVA_HOME JRE_HOME PATH

3. 数据库初始化注:以下操作全部在dolphinscheduler用户下执行
先添加mysql的驱动包至DolphinScheduler 的 lib 目录下
[dolphinscheduler@node01 lib]$ ls mysql-connector-java-5.1.47.jar mysql-connector-java-5.1.47.jar
登陆数据库创建dolphinscheduler库及用户
mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci; mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO \'dolphinscheduler\'@\'%\' IDENTIFIED BY \'dolphinscheduler\'; mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO \'dolphinscheduler\'@\'localhost\' IDENTIFIED BY \'dolphinscheduler\'; mysql> flush privileges;
修改datasource.properties配置
vim conf/datasource.properties
# postgre # spring.datasource.driver-class-name=org.postgresql.Driver # spring.datasource.url=jdbc:postgresql://localhost:5432/dolphinscheduler # mysql spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://172.16.53.179:3306/dolphinscheduler?useUnicode=true& characterEncoding=UTF-8& allowMultiQueries=true spring.datasource.username=dolphinscheduler spring.datasource.password=dolphinscheduler
创建表及导入基础数据脚本
sh script/create-dolphinscheduler.sh

注意: 如果执行上述脚本报 “/bin/java: No such file or directory” 错误，请在/etc/profile 下配置 JAVA_HOME 及 PATH 变量
4. 修改运行参数
修改 conf/env 目录下的 dolphinscheduler_env.sh(修改成真实环境的地址即可)
以下是我的部署环境：
export HADOOP_HOME=/opt/cloudera/parcels/CDH/lib/hadoop export HADOOP_CONF_DIR=/etc/hadoop/conf export SPARK_HOME=/opt/cloudera/parcels/CDH/lib/spark export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera export HIVE_HOME=/opt/cloudera/parcels/CDH/lib/hive export FLINK_HOME=/opt/flink-1.12.2 export PATH=$HADOOP_HOME/bin:$SPARK_HOME/bin:$JAVA_HOME/bin:$HIVE_HOME/bin:$FLINK_HOME/bin:$PATH
修改一键部署配置文件
vim conf/config/install_config.conf
# postgresql or mysql dbtype="mysql"

db address and portdbhost=" 172.16.53.179:3306"
db usernameusername=" dolphinscheduler"
mysql库dbname=" dolphinscheduler"
mysql密码password=" dolphinscheduler"
zk 地址zkQuorum=" 172.16.53.179:2181,172.16.53.180:2181,172.16.53.181:2181"
安装路径installPath=" /opt/dolphinscheduler"
部署用户deployUser=" dolphinscheduler"
邮箱告警设置，默认未配置mailServerHost=" smtp.exmail.qq.com"
mail server port note: Different protocols and encryption methods correspond to different ports, when SSL/TLS is enabled, make sure the port is correct.mailServerPort=" 25"
sendermailSender=" xxxxxxxxxx"
usermailUser=" xxxxxxxxxx"
sender password note: The mail.passwd is email service authorization code, not the email login password.mailPassword=" xxxxxxxxxx"
TLS mail protocol supportstarttlsEnable=" true"
SSL mail protocol support only one of TLS and SSL can be in the true state.sslEnable=" false"
#note: sslTrust is the same as mailServerHost
sslTrust=" smtp.exmail.qq.com"
任务运行的本地目录dataBasedirPath=" /tmp/dolphinscheduler"
resource storage type: HDFS, S3, NONEresourceStorageType=" HDFS"
hdfs资源上传根路径，由于 hdfs支持本地文件系统，需要确保本地文件夹存在且有读写权限resourceUploadPath=" /dolphinscheduler"
如果上传资源保存想保存在 hadoop 上，hadoop 集群的 NameNode 启用了 HA 的话，需要将 hadoop 的配置文件 core-site.xml 和 hdfs-site.xml 放到安装路径的 conf 目录下，本例即是放到 /opt/soft/dolphinscheduler/conf 下面，并配置 namenode cluster 名称；如果 NameNode 不是 HA，则只需要将 mycluster 修改为具体的 ip 或者主机名即可.defaultFS=" hdfs://tfdservice:8020"
if resourceStorageType is S3, the following three configuration is required, otherwise please ignores3Endpoint=" http://192.168.xx.xx:9010"
s3AccessKey=" xxxxxxxxxx"
s3SecretKey=" xxxxxxxxxx"
resourcemanager 端口resourceManagerHttpAddressPort=" 8088"
if resourcemanager HA is enabled, please set the HA IPs; if resourcemanager is single, keep this value emptyyarnHaIps=" 172.16.53.179,172.16.53.180"
如果 ResourceManager 是 HA 或者没有使用到 Yarn 保持默认值即可；如果是单 ResourceManager，请配置真实的 ResourceManager 主机名或者 ipsingleYarnIp=" yarnIp1"
具备权限创建 resourceUploadPath的用户hdfsRootUser=" hdfs"
kerberos服务默认未开启，无需配置kerberosStartUp=" false"
kdc krb5 config file pathkrb5ConfPath=" $installPath/conf/krb5.conf"
keytab usernamekeytabUserName=" hdfs-mycluster@ESZ.COM"
username keytab pathkeytabPath=" $installPath/conf/hdfs.headless.keytab"
kerberos expire time, the unit is hourkerberosExpireTime=" 2"
api server 默认端口apiServerPort=" 12345"
在哪些机器上部署 DS 服务，本机选 localhostips=" 172.16.53.179,172.16.53.181,172.16.53.182,172.16.53.183,172.16.53.189,172.16.53.193"
ssh 端口，默认22sshPort=" 22"
master 服务部署在哪台机器上masters=" 172.16.53.179,172.16.53.182"
worker 服务部署在哪台机器上，并指定此 worker 属于哪一个 worker 组，下面示例的 default 即为组名workers=" 172.16.53.183:default,172.16.53.189:default,172.16.53.193:default"
报警服务部署在哪台机器上【Dolphinscheduler1.3.8集群部署】alertServer=" 172.16.53.179"
后端 api 服务部署在在哪台机器上apiServers=" 172.16.53.181"

**特别注意：如果需要用资源上传到 Hadoop 集群功能，并且 Hadoop 集群的 NameNode 配置了 HA 的话，需要开启 HDFS 类型的资源上传，同时需要将 Hadoop 集群下的 core-site.xml 和 hdfs-site.xml 复制到 /opt/dolphinscheduler/conf，非 NameNode HA 跳过次步骤**# 5. 一键部署（dolphinscheduler执行） ```bash sh install.sh

部署成功后，可以进行日志查看，日志统一存放于 logs 文件夹内

logs/ ├── dolphinscheduler-alert-server.log ├── dolphinscheduler-master-server.log |—— dolphinscheduler-worker-server.log |—— dolphinscheduler-api-server.log |—— dolphinscheduler-logger-server.log
