安装官网`
1、需要先安装JDK 1.8+，MYSQL，Zookeeper，psmisc，已安装过后无需重复安装，ubuntu 安装apt-get install psmisc
安装JDK
Mysql
Zookeeper
psmisc
安装hadoop和hive
安装Python2.7，Linux默认存在Python2.X，已存在2.7，无需安装
安装DataX
2、下载安装的tar.gz包

3、新增用户，配置免密登录，赋权（集群是所有的服务器都需要先创建好用户，目录，执行install.sh，会复制执行文件到其余的服务器，别的服务器无需配置dolphinscheduler解压包）

#解压文件包，如果修改文件可以用 mv apache-dolphinscheduler-2.0.3-bin /opt/dolphinscheduler
tar -zxvf apache-dolphinscheduler-2.0.3-bin.tar.gz
mv apache-dolphinscheduler-2.0.3-bin /opt/dolphinscheduler
#创建用户需使用 root 登录 （leo换成自己的用户，如果想修改用户可以用 userdel -r leo删除之后再新增）
#ubuntu需要检测是否是bash执行脚本，dash执行脚本会报错，ll /bin/sh
#可以通过 dpkg-reconfigure dash 弹出界面选择NO更换规则，如果没有界面，可以使用软链接替换 ln -s /bin/bash /bin/sh --force
#ll /bin/sh 查看是否变成bash
#ubuntu 新增用户 useradd -m leo -d /home/leo 设置密码 passwd leo
#集群环境都下面的命令都需要做一次
useradd leo
# 添加密码（xionglang换成自己的密码）
echo "xionglang" | passwd --stdin leo
# 配置 sudo 免密（leo换成前面新增的用户）
chmod u+w /etc/sudoers
vim /etc/sudoers
#找到 root ALL=(ALL) ALL 新增免密登录
#youuser            ALL=(ALL)                ALL
#%youuser           ALL=(ALL)                ALL
#youuser            ALL=(ALL)                NOPASSWD: ALL
#%youuser           ALL=(ALL)                NOPASSWD: ALL
#第一行：允许用户youuser执行sudo命令(需要输入密码)。
#第二行：允许用户组youuser里面的用户执行sudo命令(需要输入密码)。
#第三行：允许用户youuser执行sudo命令,并且在执行的时候不输入密码。
#第四行：允许用户组youuser里面的用户执行sudo命令,并且在执行的时候不输入密码。
leo ALL=(ALL) NOPASSWD: ALL
#保存退出
#取消sudoers的写权限
chmod u-w /etc/sudoers
sed -i 's/Defaults    requirett/#Defaults    requirett/g' /etc/sudoers
#免密登录执行sudo命令配置成功
#设置leo用户免密登录ssh文件
#切换用户
su leo
#生成免密文件
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
#验证是否免密
ssh localhost
#如果无需输入密码，就可以登录表示设置成功
#集群环境添加下面的配置信息
#配置hosts文件
vim /etc/hosts
10.0.0.195 ds1
10.0.0.196 ds2
10.0.0.198 ds3
10.0.0.199 ds4
#保存
#打通集群的SSH连接，并记录连接信息（先输入密码，之后点击yes）
for ip in ds1 ds2 ds3 ds4;
dossh-copy-id  $ip
done

4、上传包，修改包名，赋权

#修改目录权限，使得部署用户对二进制包解压后的 apache-dolphinscheduler-*-bin 目录有操作权限，
chown -R leo:leo dolphinscheduler
#新增数据包文件
mkdir /home/data/adolphinscheduler
#后面可能得添加数据库jar包，也需要检查下权限
chown -R 需要使用的用户，跟配置文件相同:需要使用的用户 /home/data/adolphinscheduler
#每个文件夹都需要赋权个创建的用户，需要检查一下

5、修改配置文件信息（10.0.0.63表示需要修改的服务器，数据库，zookeeper等路径），并修改用户名密码

#echo $PATH 可以查看JDK环境，不用带bin
vim /opt/dolphinscheduler/conf/config/install_config.conf

6、修改dolphinscheduler_env.sh

cd /opt/dolphinscheduler/conf/env
vim dolphinscheduler_env.sh
#hadoop安装目录
export HADOOP_HOME=/opt/hadoop
export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop
export SPARK_HOME1=/opt/spark1
export SPARK_HOME2=/opt/spark2
#python安装目录，确保存在/usr/bin/python2.7，可以使用软链接
export PYTHON_HOME=/usr/
#JDK安装目录
export JAVA_HOME=/opt/jdk1.8.0_101
#HIVE安装目录
export HIVE_HOME=/opt/hive
export FLINK_HOME=/opt/flink
#Datax安装路径
export DATAX_HOME=/opt/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

7、新增数据库（上面配置的用户名，密码，需要赋权，可以使用可视化工具Navicat等）
8、下载Mysql8.0.16版本驱动
mysql-connector-java

9、把驱动包放入解压包/lib下面

10、执行初始化脚本，在解压包/script下面有个create-dolphinscheduler.sh脚本

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

执行完成（可以用工具查看脚本是否执行成功）


11、新增执行脚本（根据实际需要，我是需要统一一个启动脚本，可以直接执行加压包下的 install.sh）

vim dolphinscheduler.sh
#以某一个用户执行某个脚本（不切换环境，防止dolphinscheduler没有执行权限）
cd /opt/dolphinscheduler
#执行的时候如果要输入密码，那就说明免密执行有问题或者文件夹/文件权限有问题
su leo install.sh
#ubuntu执行脚本时如果出现source not found错误，使用cat xxx.sh 查看头部是否是 /bin/bash或者/bin/sh，如果是 /bin/bash可以使用 sudo bash xxx.sh
#如果java -version;javac -version;echo $PATH;echo $JAVA_HOME都整成，还是报找不到 /bin/java
#那么可以使用软链接处理
#sudo ln -s /usr/java/jdk1.8.0_301-amd64 /bin/java

保存 (ESC+:wq)，赋权

chmod +777 dolphinscheduler.sh

12、防火墙开放12345端口并重启防火墙

firewall-cmd --zone=public --add-port=12345/tcp --permanent
systemctl restart firewalld

13、启动系统

14、浏览器输入
浏览器访问地址：http://10.0.0.63:12345/dolphinscheduler
默认的用户名和密码是 ：admin dolphinscheduler123

15、打开页面失败，可以查看日志信息
tail -f -n 300 (installPath路径)/logs/dolphinscheduler-master.log
比如CPU过高，内存过低

16、集群环境启动


17、优化配置
（一）、Hive执行时间过长，默认30s，内存过低，容易超时；
org.apache.dolphinscheduler.plugin.task.sql.SqlTask

org.apache.dolphinscheduler.plugin.datasource.api.provider.JdbcDataSourceProvider
