java - TeamCity 服务器找不到 java (ubuntu)

Question

Ubuntu 18.04

sudo ./teamcity-server.sh 运行

Java executable of version 1.8 is not found:
- Java executable is not found under the specified directories: '', '/home/alex/TeamCity/bin/../jre'
- Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
- Java executable is not found in the default locations
- Java executable is not found in the directories listed in the PATH environment variable

Please make sure either JAVA_HOME or JRE_HOME environment variable is defined and is pointing to the root directory of the valid Java (JRE) installation

Environment variable FJ_DEBUG can be set to enable debug output

Java not found. Cannot start TeamCity server. Please ensure JDK or JRE is installed and JAVA_HOME environment variable points to it.

java版本

openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)
alex@teamcity-server:~/TeamCity/bin$

$JAVA_HOME(尝试过 default-java，/bin)

-bash: /usr/lib/jvm/java-11-openjdk-amd64: Is a directory

$JRE_HOME(尝试过 default-java，/bin)

-bash: /usr/lib/jvm/java-11-openjdk-amd64: Is a directory

回声 $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/bin:/usr/bin:/sbin:/usr/games:/usr/local/games:/usr/lib/jvm/java-11-openjdk-amd64/bin

readlink -f $(哪个java)

/usr/lib/jvm/java-11-openjdk-amd64/bin/java

试过了

ln -s /usr/lib/jvm/java-11-openjdk-amd64/bin /home/alex/TeamCity/jre

它是否需要特定的 java 版本并且不适用于最新版本？

我是否错误地设置了变量？

Answer 1

我猜，TeamCity 期待 Java 1.8

Java executable of version 1.8 is not found.

但是你用 Java 10 喂它

openjdk version "10.0.2"

我认为答案

Is it requires SPECIFIC java version and does not work with latest?

是“是。”，它可能只需要 Java 1.8。
