DolphinScheduler-2.0.0 安装部署

2023-12-27 13:59:06

一、环境准备

Centos 6.5 三台（192.168.206.5? ?192.168.206.6? ?192.168.206.7）
Zookeeper:?3.4.6?左右
JDK:?JDK1.8+ 左右
Mysql：5.1.47+

二、准备工作

1、配置host (三台)

[root@master03 ~]# cat >>/etc/hosts<<EOF
192.168.206.5 node1
192.168.206.6 node2
192.168.206.7 node3
EOF

2、安装openjdk

安装此处略过

[root@master01 ~]# which java
/bin/java
[root@master01 ~]#
[root@master01 ~]# ll /bin/java
lrwxrwxrwx 1 root root 23 7月  18 09:40 /bin/java -> /data/java/jre/bin/java
[root@master01 ~]#
[root@master01 ~]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

3、Zookeeper集群

(node1操作)

下载 apache-zookeeper-3.6.4-bin

Index of /dist/zookeeper

cd /opt/src
sz apache-zookeeper-3.6.4-bin.tar.gz
tar -zxvf apache-zookeeper-3.6.4-bin.tar.gz
mv apache-zookeeper-3.6.4-bin /opt/
ln -s apache-zookeeper-3.6.4-bin/ zookeeper
cd /opt/zookeeper/conf
cp -r zoo_sample.cfg  zoo.cfg

vi zoo.cfg

dataDir=/opt/zookeeper/var/data
dataLogDir=/opt/zookeeper/var/datalog
clientPort=2181
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

grep -v "^#\|^$" zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/var/data
dataLogDir=/opt/zookeeper/var/datalog
clientPort=2181
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

scp -r apache-zookeeper-3.6.4-bin/ node2:/opt/
scp -r apache-zookeeper-3.6.4-bin/ node3:/opt/

(node2 node3 操作)

cd /opt/src
ln -s apache-zookeeper-3.6.4-bin/ zookeeper

(node1 node2 node3 操作)?

启动

cd /opt/zookeeper/bin
./zkServer.sh start

查看状态

cd /opt/zookeeper/bin
./zkServer.sh status

4、配置免密

DolphinScheduler 集群默认的启动脚本是 start-all.sh，看名字就是启动一个节点，所有的节点都会启动，他是通过 ssh 启动其他节点，故需要配置免密

（node1 node2 node3 ）

[root@ jerry7-11 ~]# ssh-keygen -t rsa   //默认指定算法的是rsa，可以没有-t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):   
//保存私钥的路径默认/root/.ssh/id_rsa，可以指定生成地址
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):   //密码
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.  生成私钥
Your public key has been saved in /root/.ssh/id_rsa.pub.  生成公钥
The key fingerprint is:
SHA256:PXTg9KW4P582PWJMEwUstPfyXk6NWdrB518yCORbisc root@hdss7-11
The key's randomart image is:
+---[RSA 2048]----+
|          +...o  |
|         o =.+ . |
|          =.=..  |
|         = o..o  |
|        S * ...+o|
|         o B +oB+|
|        . E * BoB|
|         .   *+B=|
|            ..+o+|
+----[SHA256]-----+

[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@192.168.206.5
[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@192.168.206.6
[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@192.168.206.7
[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@node1
[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@node2
[root@master01 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub -p22 root@node3

5、部署mysql

此处略，借鉴?Linux（CentOS 7）下安装 MySQL 8.0.31_centos 使用yum安装mysql8.0.31-CSDN博客

6、下载DolphinScheduler

（node1 操作）

此处略，去官网下载 apache-dolphinscheduler-2.0.0-alpha-bin.tar.gz

cd /opt/src
rz apache-dolphinscheduler-2.0.0-alpha-bin.tar.gz
tar -zxf apache-dolphinscheduler-2.0.0-alpha-bin.tar.gz

7、下载mysql-connector-java.jar驱动

去官网?MySQL :: MySQL Downloads，点击下方的Mysql?Community?Downloads。

然后单击选择 Connector/J选项:

点击?Archives

选择数据库版本，随后点击 Platform Independent?选项

下载等待压缩包下载完毕即可：

cd /opt/src
rz mysql-connector-j-8.0.31.zip
unzip mysql-connector-j-8.0.31.zip
cd /opt/src/mysql-connector-j-8.0.31
mv mysql-connector-j-8.0.31.jar mysql-connector-java-8.0.31.jar

三、部署DolphinScheduler

3.1、DolphinSchedule源数据库配置

（node1 操作）

1、创建数据库

在安装mysql的节点创建Dolphin的元数据库

mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci; -- 创建数据库并指定编码格式

开启权限

create USER 'dolphinscheduler'@'%'  IDENTIFIED WITH mysql_native_password BY '123456';

grant all on dolphinscheduler.* to 'dolphinscheduler'@'%';

flush privileges;

注意事项：要用root账户操作

低版本

-- 赋权
mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '用户名'@'%' IDENTIFIED BY '密码';
-- 如果提示'Your password does not satisfy the current policy requirements'就说明这个密码不符当前的密码策略,可以执行如下命令
mysql> set global validate_password_policy=LOW; -- 验证密码等级强度
mysql> set global validate_password_length=6; -- 设置密码长度
mysql> flush privileges; -- 刷新权限

3.2、DolphinScheduler配置及安装

3.2.1 驱动配置

cp /opt/src/mysql-connector-j-8.0.31/mysql-connector-java-8.0.31.jar /opt/src/apache-dolphinscheduler-2.0.0-alpha-bin/lib/

3.2.2 配置文件修改

3.2.2.1 修改数据源配置

修改conf目录下的datasource.properties配置文件]

vi datasource.properties

#修改内容如下

# datasource configuration
#spring.datasource.driver-class-name=org.postgresql.Driver
#spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/dolphinscheduler
#spring.datasource.username=root
#spring.datasource.password=root

# mysql 因为这里使用的mysql作为元数据库,所以要将上面postgresql的配置注释掉
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.206.5:3306/dolphinscheduler?characterEncoding=UTF-8&allowMultiQueries=true
spring.datasource.username=dolphinscheduler
spring.datasource.password=123456

#保存退出即可

执行脚本初始化元数据

dolphin已经为我们准备了初始化元数据库的脚本,执行script目录下的create-dolphinscheduler.sh脚本即可

./create-dolphinscheduler.sh
# 如果在部署完所有的步骤后,访问DolphinScheduler界面创建项目时,发现提示元数据库缺少字段,可以不通过create-dolphinscheduler.sh这个脚本初始化元数据库,可以将/opt/apps/apache-dolphinscheduler-2.0.0-alpha-bin/sql这个目录下的dolphinscheduler_mysql.sql这个文件在mysql中直接执行用来创建元数据表,在mysql中执行命令:source //opt/apps/apache-dolphinscheduler-2.0.0-alpha-bin/dolphinscheduler_mysql.sql

执行完成后移可以去我们已经在mysql建立的dolphinscheduler库中查看一下

mysql> show tables;
+----------------------------------------+
| Tables_in_dolphinscheduler             |
+----------------------------------------+
| QRTZ_BLOB_TRIGGERS                     |

| t_ds_master_server                     |
| t_ds_plugin_define                     |
| t_ds_process_definition                |
-- 这里就不全部展示了

3.2.2.2 修改各组件环境变量

这里用到什么组件就修改什么就可了,没有使用到的组件可直接注释掉,修改/conf/env目录下的dolphinscheduler_env.sh配置文件

export HADOOP_HOME=/opt/apps/hadoop
export HADOOP_CONF_DIR=/opt/apps/hadoop/etc/hadoop
export SPARK_HOME1=/opt/apps/spark1
export SPARK_HOME2=/opt/apps/spark2
export PYTHON_HOME=/opt/apps/python
export JAVA_HOME=/data/java
export HIVE_HOME=/opt/apps/hive
export FLINK_HOME=/opt/apps/flink
export DATAX_HOME=/opt/apps/datax

export PATH=$HADOOP_HOME/bin:$SPARK_HOME1/bin:$SPARK_HOME2/bin:$PYTHON_HOME/bin:$JAVA_HOME/bin:$HIVE_HOME/bin:$FLINK_HOME/bin:$DATAX_HOME/bin:$PATH

3.2.2.3修改Dolphin安装配置

修改/conf/config目录下的install_config.conf配置文件，案例如下

vi ./install_config.conf

3.2.2.4 安装

安装中问题，提示没有dolphinscheduler用户，三台都操作

groupadd dolphinscheduler
useradd -g dolphinscheduler-m -d /home/dolphinscheduler -s /bin/bash dolphinscheduler

执行apache-dolphinscheduler-2.0.0-alpha-bin目录下的install.sh脚本进行安装部署

./install.sh

安装完成后DolphinScheduler会自动启动,可通过jps命令查看服务是否已经启动

jps
