配置修改

此处的配置修改按照本站之前博客路径进行修改
创建，修改java.policy文件

touch /opt/es/config/java.policy vi /opt/es/config/java.policy #修改如下 grant codeBase "file:${user.home}/.arthas/lib/-" { permission java.io.FilePermission "${user.home}/.arthas/-", "read,write"; permission java.io.FilePermission "${user.home}/logs/arthas/-", "read,write,delete"; permission java.lang.RuntimePermission "createClassLoader"; permission java.lang.RuntimePermission "getClassLoader"; permission java.lang.RuntimePermission "modifyThreadGroup"; permission java.lang.RuntimePermission "modifyThread"; permission java.lang.RuntimePermission "shutdownHooks"; permission java.lang.RuntimePermission "accessClassInPackage.sun.reflect"; permission java.lang.RuntimePermission "accessClassInPackage.sun.net.www.protocol.http"; permission java.lang.RuntimePermission "accessClassInPackage.sun.net.www.http"; permission java.net.SocketPermission "127.0.0.1:3658", "listen,resolve"; permission java.net.SocketPermission "127.0.0.1:8563", "listen,resolve"; permission java.net.SocketPermission "*", "accept"; }; #增加jvm启动参数 echo "-Djava.security.policy=file:///opt/es/config/java.policy" >> /opt/es/config/jvm.options

修改/opt/es/jdk/conf/security/java.policy配置

vi /opt/es/jdk/conf/security/java.policy #增加如下配置 grant { permission org.elasticsearch.ThreadPermission "modifyArbitraryThreadGroup"; permission org.elasticsearch.ThreadPermission "modifyArbitraryThread"; };grant { permission java.io.FilePermission "<<ALL FILES>>", "read,write"; permission java.util.PropertyPermission "JM.LOG.PATH", "write"; permission java.lang.RuntimePermission "*"; permission java.lang.reflect.ReflectPermission "*"; permission java.net.SocketPermission "*", "connect,listen,resolve,accept"; permission ognl.OgnlInvokePermission "*"; };

启动elasticsearch

/opt/es/bin/elasticsearch -d
