这是一段 shell 脚本,主要是设置一些环境变量。其中:
- JAVA_HOME 设置了 Java 的安装路径为 /usr/java/jdk1.8.0_361
- FLUME_HOME 设置了 Flume 的安装路径为 /usr/local/flume
- FLUME_CONF_DIR 设置了 Flume 的配置文件路径为 $FLUME_HOME/conf
- PATH 添加了 Flume 和 HBase 的二进制文件路径,以及 ZooKeeper 的 bin 目录
- ZOOKEEPER_HOME 设置了 ZooKeeper 的安装路径为 /home/hadoop/zookeeper
- PATH 再次添加了 ZooKeeper 的 bin 目录
这样设置环境变量可以方便地在命令行中使用这些工具。

java_home java_home=/usr/local/jdk1.8.0_341 dose notexists
java_home=/usr/local/jdk1.8.0_341不存在。这个错误表示在指定的路径下找不到所需的Java Development Kit (JDK)。要解决这个问题,可以按照以下步骤进行操作:
首先,确认系统中是否已经正确安装了Java Development Kit (JDK)。可以使用命令`java -version`来检查Java是否已经安装,如果没有安装,则需要先下载并安装相应的JDK版本。
然后,确认所指定的java_home路径是否正确。在这个例子中,指定的路径为/usr/local/jdk1.8.0_341,所以需确保该路径下存在jdk1.8.0_341文件夹,并且其中包含JDK所需的文件和目录。
如果确认安装和路径都正确,但仍然报错,可以尝试重新设置java_home路径。可以通过在终端中输入以下命令来设置java_home的环境变量:
export JAVA_HOME=/usr/local/jdk1.8.0_341
然后,使用`echo $JAVA_HOME`命令来确认java_home已经设置为指定的路径。
如果还是无法解决问题,可能需要重新安装JDK,或者尝试其他版本的JDK。同时,可以查阅JDK文档和相关资源,以寻找更多的解决方案。
export CATALINA_HOME=/usr/local/tomcat
Sorry, as an AI language model, I do not have access to the operating system's environment variables. However, to set the CATALINA_HOME environment variable, you can follow these steps:
1. Open the terminal or command prompt.
2. Navigate to the directory where Tomcat is installed. For example, if Tomcat is installed in /usr/local/tomcat, then run the following command:
`cd /usr/local/tomcat`
3. Set the CATALINA_HOME environment variable by running the following command:
`export CATALINA_HOME=/usr/local/tomcat`
This command sets the CATALINA_HOME variable to the directory where Tomcat is installed.
4. To verify that the environment variable is set correctly, run the following command:
`echo $CATALINA_HOME`
This command should output the directory where Tomcat is installed.
Note: The above steps assume that you are using a Unix-based operating system. If you are using a Windows operating system, you can set environment variables through the System Properties menu or through the command prompt using the `set` command instead of `export`.
