dolphinscheduler部署

dolphinscheduler部署

1 安装jdk(已安装可忽略)

• 安装jdk

# 上传jdk安装包
rpm -ivh jdk-8u144-linux-x64.rpm

• 配置环境变量

export JAVA_HOME=/usr/java/jdk1.8.0_144
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

source环境变量

source /etc/profile

2 安装常用软件

yum install -y openssh-server vim gcc gcc-c++ glibc-headers bzip2-devel lzo-devel curl wget openssh-clients zlib-devel autoconf automake cmake libtool openssl-devel fuse-devel snappy-devel telnet unzip zip net-tools.x86_64 firewalld systemd

3 安装MySQL(已安装可忽略)

下载安装包

-- 自己写的
wget是一个从网络上自动下载文件的工具，它支持http，https，ftp协议，可以使用http代理。
​
所谓的自动下载是指，wget可以在用户退出系统的之后在后台执行。这意味这你可以登录系统，启动一个wget下载任务，然后退出系统，wget将在后台执行直到任务完成，相对于其它大部分浏览器在下载大量数据时需要用户一直的参与，这省去了极大的麻烦。
​
常用功能：
​
-P，指定下载的文件夹
-O，这下载到的位置并且可以重命名文件
-N，如果文件不是新的就不下载了
例如：wget ftp://ip地址/路径/文件名 --ftp-user=user --ftp-password=pwd -P /aaa/bbb -N

wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

 

安装rpm包

rpm -Uvh mysql57-community-release-el7-11.noarch.rpm

检查mysql源

 -- （自己写的）
 2、yum
  我们将yum称为包管理器，主要用来解决：下载、依赖关系、安装、卸载四种问题。
​
  我们以手机为例，当我们新买了一个手机，想要下载QQ这个app，应该怎么办呢？
    ------打开应用商店app，搜寻QQ，点击下载并安装。
  同样，我们在Linux下载软件应该怎么办呢？
    ------a：源码安装
    ------b：rpm安装包
    ------c：yum
  在Linux系统中有一个yum软件服务器，上面有Linux需要的各种软件软件包，我们使用yum命令去云服务器下载我们所需要的软件，然后再本地进行安装。对于这种行为不知道大家觉得似曾相识，yum的使用本质上和手机应用商店是一样的，所以手机上的应用市场对应Linux下的yum工具。
​
2.1 yum是什么
  综上所述：yum是一个客户端软件，作用是帮助我们在远端服务器上下载对应的软件包，并解决我们在本地电脑上的一个安装问题。（好比手机上的应用市场）
​

yum repolist enabled | grep mysql

安装mysql-community-server

yum install -y mysql-community-server

启动mysql服务

systemctl start mysqld
systemctl status mysqld

 

查看初始密码

cat /var/log/mysqld.log | grep password

 

修改mysql密码

mysql -uroot -p
#输入上一步查询到的初始密码
set global validate_password_policy=LOW;
set password=password("Congf1daof4");

4 创建dolphinscheduler元数据库

-- 创建库
CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
-- 创建远程用户
GRANT ALL PRIVILEGES ON dolphinscheduler.* TO 'dolphinscheduler'@'%' IDENTIFIED BY '12345678';
-- 创建本地用户
GRANT ALL PRIVILEGES ON dolphinscheduler.* TO 'dolphinscheduler'@'localhost' IDENTIFIED BY '12345678';
flush privileges;

5 配置dolphinscheduler用户sudo免密

#配置sudo免密
sed -i '$adolphinscheduler  ALL=(ALL)  NOPASSWD: NOPASSWD: ALL' /etc/sudoers
sed -i 's/Defaults    requirett/#Defaults    requirett/g' /etc/sudoers

6 配置dolphinscheduler 用户ssh免密

# 添加用户
useradd dolphinscheduler
# 设置密码 12345678
passwd dolphinscheduler
# 生成秘钥
su - dolphinscheduler
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
# 验证免密是否生效
ssh localhost
# 不需要输入密码可以ssh成功，即配置ssh成功

7 部署zookeeper(已安装可忽略)

cdh已经部署，可以忽略

# 提前上传zk包
tar -zxvf zookeeper-3.4.8.tar.gz -C /usr/local/
mv /usr/local/zookeeper-3.4.8/ /usr/local/zookeeper

• 配置zookeeper path

vim /etc/profile

写入如下内容：

export PATH=$PATH:$JAVA_HOME/bin:/usr/local/zookeeper/bin

 

修改配置文件

mv /usr/local/zookeeper/conf/zoo_sample.cfg /usr/local/zookeeper/conf/zoo.cfg

启动zk

zkServer.sh start

 

8 安装dolphinscheduler

8.1 解压安装dolphinscheduler

cd /opt
#提前上传安装包
​
mkdir -p /opt/dolphinscheduler
# 解压
tar -zxvf apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin.tar.gz -C /opt/dolphinscheduler
cd /opt/dolphinscheduler
mv apache-dolphinscheduler-incubating-1.3.5-dolphinscheduler-bin  dolphinscheduler-bin
#修改所有者
chown -R dolphinscheduler:dolphinscheduler dolphinscheduler-bin

 

8.2 修改数据源配置并初始化数据表

vim /opt/dolphinscheduler/dolphinscheduler-bin/conf/datasource.properties 

注释掉默认的postgresql的配置，增加MySQL的配置

#mysql
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
# 需要修改ip，本机localhost即可
spring.datasource.url=jdbc:mysql://192.168.88.222:3306/dolphinscheduler?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
#需要修改为上面的{user}值
spring.datasource.username=dolphinscheduler
#需要修改为上面的{password}值
spring.datasource.password=12345678

 

加载mysql驱动

mv mysql-connector-java-5.1.35.jar /opt/dolphinscheduler/dolphinscheduler-bin/lib/
​

创建表及初始化

sh /opt/dolphinscheduler/dolphinscheduler-bin/script/create-dolphinscheduler.sh

 

查看MySQL，调度系统的表已经初始化

 

8.3 修改dolphinscheduler环境变量配置

vim /opt/dolphinscheduler/dolphinscheduler-bin/conf/env/dolphinscheduler_env.sh

写入如下内容：

export JAVA_HOME=/usr/java/latest
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/zookeeper/bin

 

source 使得脚本环境生效

# 使得配置生效
source /opt/dolphinscheduler/dolphinscheduler-bin/conf/env/dolphinscheduler_env.sh
# 测试zookeeper客户端，能进入zookeeper客户端即可
zkCli.sh -server worker-1:2181

8.4 一键安装配置修改

vim /opt/dolphinscheduler/dolphinscheduler-bin/conf/config/install_config.conf

修改为自己环境的配置

# 创建安装目录并授权
sudo mkdir -p /opt/soft/dolphinscheduler
sudo chown dolphinscheduler:dolphinscheduler /opt/soft/dolphinscheduler
​
# 创建资源中心目录并授权
sudo mkdir -p /data/dolphinscheduler
sudo chown -R dolphinscheduler:dolphinscheduler /data/dolphinscheduler

虚拟机安装，注意事项：

有个脚本文件需要修改配置

vim /opt/dolphinscheduler/dolphinscheduler-bin/bin/dolphinscheduler-daemon.sh

修改内存大小

 

修改master端口

由于master端口默认是5678， 端口可能被占用，可将端口改成 54321。

vim /opt/dolphinscheduler/dolphinscheduler-bin/conf/master.properties

# 修改端口号
master.listen.port=54321

修改 /opt/dolphinscheduler/dolphinscheduler-bin/conf/common.properties

 

8.5 执行一键安装

su - dolphinscheduler
sh /opt/dolphinscheduler/dolphinscheduler-bin/install.sh

安装启动后目录：

         

安装启动后进程：

 

进入web页面

http://192.168.88.197:12345/dolphinscheduler/ui/view/login/index.html

默认用户名/密码：

admin / dolphinscheduler123

登录后进入主页：

 

查看master日志，看端口是否被占用

less /opt/soft/dolphinscheduler/logs/dolphinscheduler-master.log

端口占用报错信息：
