Java 如何为Elasticsearch 6.4安装OpenJDK 10

我刚刚用openjdk-10.0.2_linux-x64_bin.tar.gz以以下方式创建了一个Solr 7.5集群

curl -O https://download.java.net/java/GA/jdk10/10.0.2/19aef61b38124481863b1413dce1855f/13/openjdk-10.0.2_linux-x64_bin.tar.gz
tar zxvf openjdk-10.0.2_linux-x64_bin.tar.gz
mv jdk-10.0.2 /usr/local/java/

cat > /etc/profile.d/jdk10.sh << EOF
#!/bin/sh
export JAVA_HOME=/usr/local/java
export PATH=\$PATH:/usr/local/java:/usr/local/java/bin
EOF

source /etc/profile.d/jdk10.sh

但是java是在路径中设置的，也是java_HOME

[root@ip-10-0-5-10 ~]# java -version
openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment 18.3 (build 10.0.2+13)
OpenJDK 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

echo $PATH = /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/java/bin:/usr/local/java:/root/bin 

这适用于root用户和ec2用户。我知道，为什么ES可以找到java？

---

看起来我应该将它安装在其中一个文件夹中：/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin

执行

路径
或
JAVA_HOME
可能有许多不同的原因，例如，在执行
/etc/profile.d/jdk10.sh之后，其他脚本会覆盖它。既然
/etc/profile.d
脚本应该在登录时运行，那么您可能还没有注销？您甚至没有提供用于启动弹性搜索的命令，它是否在自己的用户下运行

看看thread，找到它的唯一方法是一步一步地调试它。
这是一个用户错误（：我使用sudo安装elasticsearch，这就是java环境为空的原因

如果有人发现它很有用，那么这里有一种方法可以安装ES，但不需要内存和插件配置
