部署文档

基础软件安装

  • mysql (5.5+) : 必装
  • zookeeper(3.4.6) ：必装
  • hadoop(2.7.3) ：选装，资源上传，MR任务提交需要安装
  • hive(1.2.1) : 选装，hive任务提交需要安装
  • spark(1.x,2.x) : 选装，spark任务提交需要安装
  • postgresql(8.2.15+) : 选装，postgresql sql任务和postgresql 存储过程需要安装

项目编译

  • 执行编译命令：
 mvn -U clean package assembly:assembly -Dmaven.test.skip=true
  • 查看目录

正常编译完后，会在当前目录生成 target/escheduler-{version}/

    bin
    conf
    lib
    script
    sql
    install.sh
  • 说明
bin : 基础服务启动脚本
conf : 项目配置文件
lib : 项目依赖jar包，包括各个模块jar和第三方jar
script : 集群启动、停止和服务监控启停脚本
sql : 项目依赖sql文件
install.sh : 一键部署脚本

数据库初始化

  • 创建db和账号
mysql -h {host} -u {user} -p{password}
mysql> CREATE DATABASE escheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> GRANT ALL PRIVILEGES ON escheduler.* TO '{user}'@'%' IDENTIFIED BY '{password}';
mysql> GRANT ALL PRIVILEGES ON escheduler.* TO '{user}'@'localhost' IDENTIFIED BY '{password}';
mysql> flush privileges;
  • 创建表
说明：在 target/escheduler-{version}/sql/escheduler.sql和quartz.sql

mysql -h {host} -u {user} -p{password} -D {db} < escheduler.sql

mysql -h {host} -u {user} -p{password} -D {db} < quartz.sql

创建部署用户

因为escheduler worker 都是以 sudo -u {linux-user} 方式来执行作业，所以部署用户需要有 sudo 权限，而且是免密的。

vi /etc/sudoers

# 部署用户是 escheduler 账号
escheduler  ALL=(ALL)       NOPASSWD: NOPASSWD: ALL

# 并且需要注释掉 Default requiretty 一行
#Default requiretty

配置文件说明

说明：配置文件位于 target/escheduler-{version}/conf 下面

伪分布式部署

1，创建部署用户

​ 如上 创建部署用户

2，根据实际需求来创建HDFS根路径

​ 根据 common/common.properties 中 hdfs.startup.state 的配置来判断是否启动HDFS，如果启动，则需要创建HDFS根路径，并将 owner 修改为部署用户，否则忽略此步骤

3，项目编译

​ 如上进行 项目编译

4，修改配置文件

​ 根据 配置文件说明 修改配置文件和 环境变量 文件

5，创建目录并将环境变量文件复制到指定目录

  • 创建 common/common.properties 下的data.basedir.path、data.download.basedir.path和process.exec.basepath路径

  • 将**.escheduler_env.sh** 和 escheduler_env.py 两个环境变量文件复制到 common/common.properties配置的escheduler.env.path 和 escheduler.env.py 的目录下，并将 owner 修改为部署用户

6，启停服务

  • 启停Master
sh ./bin/arklifter-daemon.sh start master-server
sh ./bin/arklifter-daemon.sh stop master-server
  • 启停Worker
sh ./bin/arklifter-daemon.sh start worker-server
sh ./bin/arklifter-daemon.sh stop worker-server
  • 启停Api
sh ./bin/arklifter-daemon.sh start api-server
sh ./bin/arklifter-daemon.sh stop api-server
  • 启停Logger
sh ./bin/arklifter-daemon.sh start logger-server
sh ./bin/arklifter-daemon.sh stop logger-server
  • 启停Alert
sh ./bin/arklifter-daemon.sh start alert-server
sh ./bin/arklifter-daemon.sh stop alert-server

5，修改 install.sh

​ 修改 install.sh 中变量的值，替换成自身业务所需的值

6，一键部署

  • 安装 pip install kazoo

  • 使用部署用户 sh install.sh 一键部署

服务监控

monitor_server.py 脚本是监听，master和worker服务挂掉重启的脚本

注意：在全部服务都启动之后启动

nohup python -u monitor_server.py > nohup.out 2>&1 &
