elasticsearch集群安装

 elasticsearch单机快速安装
进入到容器中

docker exec -it centos_arthas /bin/bash

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

安装arthas

配置环境变量（这里使用es自带的jdk）

echo 'export JAVA_HOME=/opt/es/jdk' >>  ~/.bashrc

echo 'export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar' >> ~/.bashrc

echo 'export PATH=$JAVA_HOME/bin:$PATH' >> ~/.bashrc

chmod +x ~/.bashrc

source ~/.bashrc
