future versions of Elasticsearch will require Java 11; your Java version from [/data/jdk1.8.0_261/jre] does not meet this requirement

这个问题是关于 Elasticsearch 的 Java 版本兼容性问题。它表明,未来的 Elasticsearch 版本将需要 Java 11 或更高版本,而你当前使用的是 Java 8,不符合该要求。因此,你需要升级你的 Java 版本到 11 或更高版本,以便能够使用未来的 Elasticsearch 版本。

Running with Java 8 from /export/server/jdk1.8.0_251/jre, which is older than the minimum required version (Java 11). Supported Java versions are: [11, 17] See https://jenkins.io/redirect/java-support/ for more information.
这个错误提示表示你的 Jenkins 需要运行在 Java 11 或者更高版本上,而你当前使用的是 Java 8,因此需要升级 Java 版本才能正常运行。
要解决这个问题,可以按照以下步骤进行操作:
1. 下载并安装 Java 11 或更高版本,可以从 Oracle 官网上下载:https://www.oracle.com/java/technologies/downloads/
2. 设置 Java 环境变量,将 Java 11 的路径加入到 PATH 环境变量中。例如,在 bash shell 下,可以执行以下命令:
```
export JAVA_HOME=/path/to/java/11
export PATH=$JAVA_HOME/bin:$PATH
```
3. 重新启动 Jenkins,使用新的 Java 11 运行 Jenkins。如果你是使用 systemd 管理 Jenkins 的服务,可以执行以下命令重启 Jenkins:
```
sudo systemctl restart jenkins
```
4. 确认 Jenkins 已经使用了正确的 Java 版本。可以在 Jenkins 的系统信息页面中查看 Java 版本信息,确认是否已经升级到 Java 11 或更高版本。
ERROR: JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.362.b08-1.el7_9.x86_64/jre/bin/java does not exist.
This error message indicates that the system is unable to locate the Java Development Kit (JDK) installation directory. The JAVA_HOME environment variable should point to the root directory of the JDK installation, not the JRE directory.
To fix this error, you need to set the JAVA_HOME environment variable to the correct directory. To determine the correct directory, you can use the following command:
$ sudo update-alternatives --config java
This command will display a list of installed Java versions and their installation paths. Once you have determined the correct path, update the JAVA_HOME environment variable in your shell profile (e.g., ~/.bashrc or ~/.bash_profile) by adding the following line:
export JAVA_HOME=/path/to/java
Make sure to replace /path/to/java with the actual path to the JDK installation directory. Save the changes and reload your shell profile by running the following command:
$ source ~/.bashrc
After this, the error should be resolved, and you should be able to use Java without any issues.
