一.准备工作
1.离线部署主要分为三块:
- MySQL离线部署
- CM离线部署
- Parcel文件离线源部署
2、规划
| 节点 | MySQL部署组件 | Parcel文件离线源 | CM服务进程 | 大数据组件 |
|---|---|---|---|---|
| hadoop001 | MySQL | Parcel | Activity Monitor | NN RM DN NM |
| hadoop002 | Alert Publisher Event Server | DN NM | ||
| hadoop003 | Host MonitorService Monitor | DN NM |
3.下载源:

二.集群节点初始化
1.阿里云上海区购买3台，按量付费虚拟机
CentOS7.2操作系统，2核8G最低配置
2.当前笔记本或台式机配置hosts文件
MAC: /etc/hosts
Window: C:windowssystem32driversetchosts
公网地址:
10.10.10.1 hadoop001
10.10.10.2 hadoop002
10.10.10.3 hadoop0033.设置所有节点的hosts文件
私有地址、内网地址:
echo "172.19.7.96 hadoop001">> /etc/hosts
echo "172.19.7.98 hadoop002">> /etc/hosts
echo "172.19.7.97 hadoop003">> /etc/hosts4.关闭所有节点的防火墙及清空规则
systemctl stop firewalld
systemctl disable firewalld
iptables -F5.关闭所有节点的selinux
vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled
设置后需要重启才能生效6.设置所有节点的时区一致及时钟同步

4.1.启动server
/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-server start
4.2.阿里云web界面，设置该hadoop001节点防火墙放开7180端口
4.3.等待1min，打开 http://hadoop001:7180 账号密码:admin/admin
4.4.假如打不开，去看server的log，根据错误仔细排查错误5.所有节点启动Agent
/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start6.接下来，全部Web界面操作
http://hadoop001:7180/
账号密码:admin/admin
7.欢迎使用Cloudera Manager--最终用户许可条款与条件。勾选
8.欢迎使用Cloudera Manager--您想要部署哪个版本？选择Cloudera Express免费版本
9.感谢您选择Cloudera Manager和CDH
10.为CDH集群安装指导主机。选择[当前管理的主机]，全部勾选
11.选择存储库
12.集群安装--正在安装选定Parcel
假如本地parcel离线源配置正确，则"下载"阶段瞬间完成，其余阶段视节点数与内部网络情况决定
13.检查主机正确性
13.1.建议将/proc/sys/vm/swappiness设置为最大值10。
swappiness值控制操作系统尝试交换内存的积极；
swappiness=0：表示最大限度使用物理内存，之后才是swap空间；
swappiness=100：表示积极使用swap分区，并且把内存上的数据及时搬迁到swap空间；
如果是混合服务器，不建议完全禁用swap，可以尝试降低swappiness。
临时调整：
sysctl vm.swappiness=10
永久调整：
cat << EOF >> /etc/sysctl.conf
# Adjust swappiness value
vm.swappiness=10
EOF
13.2.已启用透明大页面压缩，可能会导致重大性能问题，建议禁用此设置。
临时调整：
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
永久调整：
cat << EOF >> /etc/rc.d/rc.local
# Disable transparent_hugepage
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
EOF
# centos7.x系统，需要为"/etc/rc.d/rc.local"文件赋予执行权限
chmod +x /etc/rc.d/rc.local14.自定义服务，选择部署Zookeeper、HDFS、Yarn服务
15.自定义角色分配
16.数据库设置
17.审改设置，默认即可
18.首次运行
19.恭喜您!

解决:
返回到选择大数据组件的页面后，重新进行操作，就可以测试成功了。
