大家好，我是考100分的小小码 ，祝大家学习进步，加薪顺利呀。今天说一说离线部署calico_k8s自动化部署,希望您对编程的造诣更进一步.
离线CDH集群自动化部署工具
离线CDH集群安装与部署的自动化脚本工具，简单支持「离线一键装机」。
脚本将对系统配置做出一定修改，使用前请务必确认当前服务器无其他人员、任务使用，以免造成不必要的麻烦，建议提前使用测试服务器或虚拟机测试体验。
一、Features
已实现的自动化功能（仅支持Redhat/CentOS系列）：
Usage:
init_ssh|install_softs|init_sys|init_dev|init_mysql|test_sys|init_cm|install_all
- init_ssh : Configure password-free login from the control machine to other machines
- install_softs : Make a custom yum source. Includes: Install http service, extract Centos7 rpm package, ansible rpm package, cdh related software.
- init_sys : Initialize the system configuration. Includes selinux, firewall, tuned, hugepage, swappiness, tmout, kernel, maxfiles
- init_dev : Configure jdk with version jdk-8u231-linux-x64
- init_mysql : Configure the scm configuration database, initialize the hive, scm, amon, ……….. databases and authorize it
- test_sys : Test cluster network connectivity
- init_cm : Control node installation cloudera-scm-* and init the cloudera-scm-server with mysql
- install_all : Execute all scripts except init_ssh sequentially. sequen : install_softs->init_system->init_devenv->init_mysql->init_cm->test_system
二、Getting Start
在主机中选择一台执行操作过程，以下称为「控制主机」，并确保主机外网可用。
2.1 安装包准备
当前仅支持离线安装，需要提前下载所需软件安装包，如下：
- JDK
- 下载地址：Cloudera Archive CM
- 说明：版本无限制，仅支持 Oracle JDK RPM包，名称格式为 oracle-j2sdk*.rpm
- 示例安装包：jdk-8u231-linux-x64.rpm
- Mariadb
- 下载地址：Mariadb
- 说明：5.7以上版本，仅支持RPM Bundle包，名称格式为 mariadb-server.x86_64.rpm
- 示例安装包：mariadb-server.x86_64.rpm
- MySQL驱动包（5.1.46）
- 下载地址：MySQL Connector
- 说明：与MySQL版本对应，名称格式为 mysql-connector-java-*.tar.gz
- 示例安装包：mysql-connector-java-5.1.46.tar.gz
- Cloudera Manager
- 下载地址：Cloudera Archive CM
- 说明：版本无限制
- 示例安装包：
- cloudera-manager-agent.x86_64 : The Cloudera Manager Agent
- cloudera-manager-server.x86_64 : The Cloudera Manager Server
- cloudera-manager-server-db-2.x86_64 : Embedded database for the Cloudera Manager Server
- cloudera-manager-daemons.x86_64 : Provides daemons for monitoring Hadoop and related tools.
- CDH
- 下载地址：Cloudera Archive CDH
- 说明：版本无限制
- 示例安装包：
- manifest.json
- CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel
- allkeys.asc
- CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha1
- CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha256
- Centos rpm
- Centos 官网 ISO
- 说明：版本系列和机器版本保持一致
- 示例安装包：
- centos7
- ansible 安装包
- rpm仓库
- 说明：Centos7原生没有对应rpm包，自行下载
- 示例安装包：
- ansible-2.9.21-1.el7.noarch.rpm
百度云打包下载所有脚本：
链接：https://pan.baidu.com/s/1Qz_BFu0-4aOZ84nvC1FnOw
提取码：lsom
上传所有安装包至控制主机的/tmp/autocdh/路径下。
2.2 修改hosts文件
vi hosts
将集群所有节点的ip与hostname写入hosts文件中，格式同/etc/hosts，ip与hosts之间空格隔开。
示例：
192.168.1.156 autocdh1
192.168.1.157 autocdh2
192.168.1.158 autocdh3
2.3 修改配置文件
vi deploy_robot.config
- control_host: 控制主机节点hostname
- host_user: 集群主机用户名，需要有root权限
- host_passwd: 集群主机用户密码，所有主机需要一致
- contrast_host: 网络测试使用的节点hostname
- mysql_host: MySQL安装的节点hostname
- http_server_host: Http服务节点
- mysql_root_passwd: MySQL 初始化之后将使用此密码作为 root 用户密码
- cm_host: cm server节点hostname
- cm_db_passwd: cm数据库初始化密码
示例：
- control_host=autocdh3
- host_user=root
- host_passwd=123123
- contrast_host=autocdh3
- http_server_host=autocdh2
- mysql_host=autocdh1
- mysql_root_passwd=123123
- cm_host=autocdh3
- cm_db_passwd=scm
2.4 执行脚本
# 配置ssh
sh deploy_robot.sh init_ssh
# 执行安装
sh deploy_robot.sh install_all
That”s All!
# 查看server启动日志
tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
# 等待几分钟后看到 Started Jetty server.
访问cm主机的7180端口即可，账号密码为默认的admin/admin，登录即可。
三、使用说明
3.1 脚本参数
sh deploy_robot.sh
Usage: <type> init_ssh|install_softs|init_sys|init_dev|init_mysql|test_sys|init_cm|install_all
1. init_ssh : Configure password-free login from the control machine to other machines
2. install_softs : Make a custom yum source. Includes: Install http service, extract Centos7 rpm package, ansible rpm package, cdh related software.
3. init_sys : Initialize the system configuration. Includes selinux, firewall, tuned, hugepage, swappiness, tmout, kernel, maxfiles
4. init_dev : Configure jdk with version jdk-8u231-linux-x64
5. init_mysql : Configure the scm configuration database, initialize the hive, scm, amon, ........... databases and authorize it
6. test_sys : Test cluster network connectivity
7. init_cm : Control node installation cloudera-scm-* and init the cloudera-scm-server with mysql
8. install_all : Execute all scripts except init_ssh sequentially. sequen : install_softs->init_system->init_devenv->init_mysql->init_cm->test_system
执行脚本需要指定「执行类型」参数。
除了Features中各个功能的执行参数之外，install_all 将会依次执行2-7步骤。
3.2 yum软件安装列表
yum_requirements.txt 文件中描述了需要在集群各个节点上安装的软件名。
脚本执行过程中依赖相关软件，默认的软件列表不建议修改。
四、其他
4.1 注意事项
- 使用init_ssh设置免密登录时，如果已生成过ssh密钥，那么ssh的key与认证信息将被重置。如果之前配置过ssh信息请注意更新ssh key。或者选择不要执行init_ssh，手动进行ssh配置。
- 建议在即将投入生产或者干净的主机上运行，以免破坏已有生产系统环境。
- CM安装过程中不会启用SSL。
