# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files

# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the

重启 ssh 服务
sudo systemctl restart ssh
设置 ssh 服务开机启动
sudo systemctl enable ssh
上传安装包
将 jdk 和 hadoop 安装包 拖入到 deepin 窗口即可
将桌面上的安装包 剪切到 用户主目录指定位置
jdk 保存在 /home/lhz/opt/java/jdk
hadoop 保存在 /home/lhz/opt
使用命令创建
mkdir -p /home/lhz/opt/java/jdk
解压安装包
选中 jdk 安装包 右键 解压到当前文件夹
选择解压缩后的jdk目录 右键 重命名
将 jdk 安装包 重命名为 jdk-8
选中 hadoop 安装包 右键 解压到当前文件夹
选中 hadoop 解压后的目录 右键 重命名
将 hadoop 安装包 重命名为 hadoop-3
配置环境变量
打开资源管理器
进入当前用户主目录
使用快捷键 ctrl+h 显示隐藏文件
编辑 .bashrc 文件
在 .bashrc 文件 末尾追加以下内容
export JAVA_HOME=/home/lhz/opt/java/jdk/jdk-8export HADOOP_HOME=/home/lhz/opt/hadoop-3export HADOOP_INSTALL=${HADOOP_HOME}
export HADOOP_MAPRED_HOME=${HADOOP_HOME}

配置ssh免密钥登录
创建本地秘钥并将公共秘钥写入认证文件
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# 或者
ssh-copy-id hadoop
Hadoop初始化
# 格式化文件系统
hdfs namenode -format
# 启动 NameNode SecondaryNameNode DataNode
start-dfs.sh
# 查看启动进程
jps
# 看到 DataNode SecondaryNameNode NameNode 三个进程代表启动成功
# 启动 ResourceManager daemon 和 NodeManager
start-yarn.sh
# 看到 DataNode NodeManager SecondaryNameNode NameNode ResourceManager 五个进程代表启动成功
重点提示：
# 关机之前 依关闭服务
stop-yarn.sh
stop-dfs.sh
# 开机后 依次开启服务
start-dfs.sh
start-yarn.sh
或者
# 关机之前关闭服务
stop-all.sh
# 开机后开启服务
start-all.sh
#jps 检查进程正常后开启胡哦关闭在再做其它操作
