请教， CDH 集群管理工具， centos 普通用户可以安装吗？还是必须使用 root 用户

[lcdxiangzi]

用好几台机器尝试过，普通用户都在报错，sudo 也不行。一定要 root 用户直接操作才可以吗？

只要是 sudo，就会报这个错，如果 su - root 后，就可以成功。
新手上路有点懵，一般情况下 root 用户都不大用的啊。

这行没看到么......

1 楼正解

请学会阅读程序的输出，而不是全靠蒙全靠猜

[lcdxiangzi]

@liprais 报错日志肯定会看的。这个都看到了，我本地 java 都装好的。但是实际的问题是，非 root 安装就是报错，尝试了两次了。root 安装，同样的命令就可以通过。我都是尝试过的。

[lcdxiangzi]

@boris1993
@liprais
而且我本地 java 也是 1.8.x 的版本，所以有点懵逼。搞不懂

[boris1993]

所以检查 JAVA_HOME 的值对不对

[lcdxiangzi]

@boris1993
/etc/profile 内容如下
export JAVA_HOME=/home/hadoop/jdk1.8.0_161
export JRE_HOME=/home/hadoop/jdk1.8.0_161/jre
export CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export HADOOP_HOME=/home/hadoop/hadoop-3.1.1
export HIVE_HOME=/home/hadoop/apache-hive-3.1.0-bin
export HBASE_HOME=/home/hadoop/hbase-1.4.8
export ZOOKEEPER_HOME=/home/hadoop/zookeeper-3.4.12
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$HBASE_HOME/bin:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf
应该是正常的吧，因为我现在搭 cdh 用的都是之前跑过原生 hadoop 的环境。

[defunct9]

开 ssh，让我上去试试

[lcdxiangzi]

@defunct9 这个搞不定，公司的服务器，虽然是测试环境，但是肯定没有对外开放的。你需要看什么，我可以贴上来

[defunct9]

猜不了火车

[catcalse]

vi ~/.bashrc
source ~/.bashrc

[scalaer]

你看看 jps 能用不

这次是 root 用户安装的，成功了。貌似我开出来的普通用户有哪里没有配置好？算了，暂时觉得 root 一路走下去了。实在不能再等了。

大家感兴趣可以继续讨论，需要啥，告诉我，我来贴。两条路一起走吧。应该不影响的。

[fireapp]

一步步试，先 suodo yum install cloudera-manager-agent.x86_64 安装下试试

[fireapp]

再 sudo export JAVA_HOME=java_path && sudo yum install cloudera-manager-agent.x86_64 继续试

[lcdxiangzi]

@fireapp #16 试过，报错。
#17 sudo export 好像不可以合用吧，我把 sudo 拿掉，试下

[fireapp]

继续写个脚步 ，export && yum install，然后 sudo 执行它

[lcdxiangzi]

还是报错

[boris1993]

它说找不到兼容的 Java，检查下你现在安装的 Java 与工具要求的 Java 版本是否一致

[fireapp]

楼主说 su root 下能安装，但是 sudo 就报错，感觉是安装脚本在 sudo 下找不到 java_home，手动指定它试试，不行的话下个源码看看，改改自己编译一个

[lcdxiangzi]

@boris1993
@fireapp
感谢提供思路

[xiaonoah]

普通用户下执行 which java，看看你 java 安装路径是在哪里。root 用的 java 版本和普通用户的可能不一样

[sunchen]

JAVA_HOMe 改成和 CDH 要求的一致的 /usr/java/jdkxxxxx

[sunchen]

https://www.cloudera.com/documentation/enterprise/6/latest/topics/cdh_ig_jdk_installation.html#topic_29 仔细读文档

[lcdxiangzi]

@sunchen 多谢，我这里不是仔细不仔细的问题，我是压根没有看文档，网上找了个帖子就开干了。😅😅😅
吸取教训，老实看文档去了
谢谢👏👏👏
