原始文件内容

# 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
# or on the command line.

# Configuration data is parsed as follows:
#  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
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

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
hadoop" />

选中 hadoop 解压后的目录 右键 重命名
hadoop" />

将 hadoop 安装包 重命名为 hadoop-3
hadoop" />

修改Hadoop配置文件 在hadoop解压后的目录找到 etc/hadoop目录

修改如下配置文件

• hadoop-env.sh
• core-site.xml
• hdfs-site.xml
• workers
• mapred-site.xml
• yarn-site.xml

hadoopenvsh__358">hadoop-env.sh 文件末尾追加

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

hdfs" />

# 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

hadoop" />

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
