java - 无法运行命令 `/opt/jdk1.8.0_131/bin/java' : No such file or directory

Question

我的服务器上安装了java环境

java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

Java 设置变量路径:

export JAVA_HOME=/opt/jdk1.8.0_171
export JRE_HOME=/opt/jdk1.8.0_171/jre
export PATH=$PATH:/opt/jdk1.8.0_171/bin:/opt/jdk1.8.0_171/jre/bin

当我运行使用 java 的应用程序时，即使已安装，我仍然收到此错误

nohup: failed to run command `/opt/jdk1.8.0_131/bin/java': No such file or directory

Answer 1

首先像下面这样修改.bashrc文件，不需要JRE_HOME

export JAVA_HOME=/opt/jdk1.8.0_171
export PATH=$JAVA_HOME/bin:$PATH

这就足够了，并将 jdk1.8.0_171 chown 到用户级别

sudo chown user:group jdk1.8.0_171

例如sudo chown deadpool:deadpool jdk1.8.0_171 并检查 java -v 和 which java

观察错误，它正在寻找目录jdk1.8.0_131，但在路径中您的目录是jdk1.8.0_171
