Centos7.6集群部署海豚调度3.1.5

前置准备工作（所有机器）

主机规划

主机名	主机ip	角色	服务（端口）
ty-m1	10.0.1.102	master	MasterServer（5678），pg15（5432）
ty-m2	10.0.0.232	worker	WorkerServer（1234），alertServer
ty-m3	10.0.1.203	worker	WorkerServer（1234），apiServers（12345）

数据库规划

属性	值
主机名	ty-m1
主机ip	10.0.1.102
数据库版本	pg15
${PGDATABASE}	dp
${PGUSER}	dp
${PGPORT}	5432
${PGDATA}	/data/pgsql/data
${PGHOME}	/usr/local/pgsql

用户规划

用户名	权限
dp	具有sudo免密权限

# 添加用户dp
useradd dp
# 为用户dp设置密码
passwd dp
# sudo免密
sed -i '$adp  ALL=(ALL)  NOPASSWD: NOPASSWD: ALL' /etc/sudoers
sed -i 's/Defaults    requirett/#Defaults    requirett/g' /etc/sudoers

注意:

• 因为任务执行服务是以 sudo -u {linux-user} 切换不同 linux 用户的方式来实现多租户运行作业，所以部署用户需要有 sudo 权限，而且是免密的。初学习者不理解的话，完全可以暂时忽略这一点
• 如果发现 /etc/sudoers 文件中有 “Defaults requirett” 这行，也请注释掉

目录规划

目录	用途	归属
/usr/local/jdk-20	jdk安装目录	root
/usr/local/zookeeper	zookeeper安装目录	root
/data/zookeeper/data	zookeeper数据目录	root
/usr/local/dolphinscheduler-app	海豚调度UI安装目录	dp
/usr/local/dolphinscheduler	海豚调度二进制目录	dp

mkdir -p /data/zookeeper/data
mkdir -p /usr/local/dolphinscheduler-app
chown -R dp.dp /usr/local/dolphinscheduler-app

配置/etc/hosts

echo '
10.0.1.102 ty-m1
10.0.0.232 ty-m2
10.0.1.203 ty-m3' >> /etc/hosts

jdk安装

# 我们把下载的东西全放在 /opt 下
# 下载jdk20
cd /opt && wget https://download.oracle.com/java/20/latest/jdk-20_linux-x64_bin.tar.gz
cd /usr/local/ && tar -zxvf /opt/jdk-20_linux-x64_bin.tar.gz
# 配置环境变量 JAVA_HOME 和 PATH
echo 'export JAVA_HOME=/usr/local/jdk-20
export PATH=$PATH:$JAVA_HOME/bin
' >> /etc/profile
# 使环境变量立即生效
source /etc/profile

进程树分析

• macOS安装pstree
• Fedora/Red/Hat/CentOS/Ubuntu/Debian安装psmisc
• DolphinScheduler 本身不依赖 Hadoop、Hive、Spark，但如果你运行的任务需要依赖他们，就需要有对应的环境支持

yum -y install psmisc

配置ssh免密

# 切换到dp用户
su - dp
# 生成公钥
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
# 将公钥分发到所有机器上
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 dp@ty-m1
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 dp@ty-m2
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 dp@ty-m3
chmod 600 ~/.ssh/authorized_keys

# 测试
ssh localhost
ssh ty-m1
ssh ty-m2
ssh ty-m3

部署zookeeper

# 切回root
exit

cd /opt && wget https://dlcdn.apache.org/zookeeper/zookeeper-3.7.1/apache-zookeeper-3.7.1-bin.tar.gz --no-check-certificate
cd /usr/local/ && tar -zxvf /opt/apache-zookeeper-3.7.1-bin.tar.gz && mv /usr/local/apache-zookeeper-3.7.1-bin /usr/local/zookeeper
echo '
# The number of milliseconds of each tick

# synchronization phase can take
