启动服务时出现Elasticsearch错误

Question

我有问题启动elasticsearch，启动命令是:

cd /etc/init.d && ./elasticsearch start

把

。

/opt/jdk1.8.0_77 uno
JAVA /opt/jdk1.8.0_77/bin/java
Starting elasticsearch:                                    [  OK  ]

但执行状态我得到:"elasticsearch dead but subsys locked"

我尝试删除"elasticsearch"，在/var/lock/subsys中，但是，这个文件又生成了。

在日志中说。

java.lang.RuntimeException: Java version: 1.7.0_40 suffers from critical bug https://bugs.openjdk.java.net/browse/JDK-8024830 which can cause data corruption.
Please upgrade the JVM, see http://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html for current recommendations.
If you absolutely cannot upgrade, please add -XX:-UseSuperWord to the JVM_OPTS environment variable.
Upgrading is preferred, this workaround will result in degraded performance.

但是这个过程是从java 8开始的，

elasticsearch      26918  0.8  1.0 30526952 724324 ?

验证java选择

options——config java

确保java 8正在使用中。Elasticsearch至少需要Java 8。

请尝试设置/etc/elasticsearch/elasticsearch.yml中的变量:

路径。数据:数据路径//

路径。工作:工作路径//

路径。日志:/var/log/elasticsearch

path.conf:/etc/elasticsearch

注意:允许访问用户elasticsearch;对于那个文件夹elasticsearch用途:

chown -R elasticsearch/path/to/data
