ubuntu 安装 elasticsearch-5.4.0

一. 使用Elasticsearch必须安装jdk环境

  1 Java 8 下载地址

1. http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html

  2 以root用户登录将下载的jdk-8u92-linux-x64.tar.gz文件放到/temp目录下，使用如下命令解压

1. tar zxvf jdk-8u92-linux-x64.tar.gz

3 将解压后的jdk1.8.0_92复制到/opt下，命令如下：

root@test:~# mkdir /temp
root@test:~# cd /temp
root@test:/temp# tar zxvf jdk-8u92-linux-x64.tar.gz 
root@test:/temp# cd /opt
root@test:/opt# mv /temp/jdk1.8.0_92/ .
root@test:/opt# ls -l
总用量 4
drwxr-xr-x 8 uucp 143 4096 4月 1 12:20 jdk1.8.0_92

4 在/bin目录下创建java软链接

root@test:/opt# cd /bin
root@test:/bin# ln -s /opt/jdk1.8.0_92/bin/java java

　　验证软件接的正确性

root@test:/bin# java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

5 设置Java环境

root@test:/bin# gedit /etc/profile
export JAVA_HOME=/opt/jdk1.8.0_92
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH={JAVA_HOME}/bin:$PATH
root@test:/bin# source /etc/profile
root@test:/bin# echo $JAVA_HOME
/opt/java1.8.0_92

6 切换到其它用户验证

ccskun@test:~$ echo $JAVA_HOME
/opt/jdk1.8.0_92
ccskun@test:~$ java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

 

二. JDK安装完成后，下载Elasticsearch的压缩包。

　　1.wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.4.0.zip

　　  2.下载完成后，我们来对下载的压缩包进行一下校验。

　　　　sha1sum elasticsearch-5.4.0.zip

　　  3.unzip elasticsearch-5.4.0.zip

　　  4.配置文件修改

　　  5.执行 ./bin/elasticsearch 启动

　　

使用root账号启动es后 会遇到以下问题　　

　　1. [WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread

　　　　[main]

 

　　　　org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run 　　　　elasticsearch as root

 

　　解决方案：

 

　　因为安全问题elasticsearch 不让用root用户直接运行，所以要创建新用户

　　建议创建一个单独的用户用来运行ElasticSearch　

　　创建elsearch用户组及elsearch用户

groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
passwd elsearch

　　2.ERROR Could not register mbeans java.security.AccessControlException: access denied 　　　　　　("javax.management.MBeanTrustPermission" "register")

　　解决方案：　 

　　改变elasticsearch文件夹所有者到当前用户

　　sudo chown -R noroot:noroot elasticsearch

 　  3.Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12)

　　由于elasticsearch5.0默认分配jvm空间大小为2g，修改jvm空间分配

# vim config/jvm.options  
-Xms2g  
-Xmx2g  

 

　　修改为

-Xms512m  
-Xmx512m  

 

启动成功
