使用“start-dfs.sh”权限启动 Hadoop 文件系统被拒绝

我尝试在独立节点上安装 hbase，但是在启动 Hadoop 文件系统时遇到一些问题start-dfs.sh：

mike@mike-thinks:/usr/local/hadoop/sbin$ ./start-dfs.sh 
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Starting namenodes on []
./start-dfs.sh: line 61: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
./start-dfs.sh: line 74: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
Starting secondary namenodes [0.0.0.0]
./start-dfs.sh: line 87: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied

使用 sudo 的话：

mike@mike-thinks:/usr/local/hadoop/sbin$ sudo ./start-dfs.sh 
[sudo] password for mike: 
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Starting namenodes on []
./start-dfs.sh: line 61: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
./start-dfs.sh: line 74: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
Starting secondary namenodes [0.0.0.0]
./start-dfs.sh: line 87: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied

所以我做了sudo chmod +x /usr/local/hadoop/sbin/

mike@mike-thinks:/usr/local/hadoop/sbin$ sudo chmod +x /usr/local/hadoop/sbin/
[sudo] password for mike: 
mike@mike-thinks:/usr/local/hadoop/sbin$ ./start-dfs.sh 
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Starting namenodes on []
./start-dfs.sh: line 61: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
./start-dfs.sh: line 74: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied
Starting secondary namenodes [0.0.0.0]
./start-dfs.sh: line 87: /usr/local/hadoop/sbin/hadoop-daemons.sh: Permission denied

我还没有尝试进入 sshd_config，将 PermitRootLogin without-password 更改为 PermitRootLogin yes，然后按照 gsamaras 的建议重启 ssh相关问题但这似乎不太可能联系起来。

我做了一个chmod +x *.sh并解决了这个问题。现在我有一个Incorrect configuration错误：

mike@mike-thinks:/usr/local/hadoop/sbin$ ./start-dfs.sh 
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.

答案1

# Create the .ssh directory:
$ mkdir ~/.ssh

# Set the right permissions:
$ chmod 700 ~/.ssh

# Create the authorized_keys file:
$ touch ~/.ssh/authorized_keys

# Set the right permissions:
$ chmod 600 ~/.ssh/authorized_keys

权限很重要！没有正确的权限就无法工作！

现在您可以将公钥添加到authorized_keys文件中：

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

最后你可以执行：

$ ./start-dfs.sh
