配置JDK1.8
使用wget 下载elasticsearch安装包
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.8.tar.gz
解压
tar -zxvf elasticsearch-5.6.8.tar.gz
官网:https://www.elastic.co/products/elasticsearch
外网访问配置:
config目录下面elasticsearch.yml
修改为 network.host: 0.0.0.0
1、问题一
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /usr/local/software/temp/elasticsearch-6.2.2/hs_err_pid1912.log
解决1:内存不够,购买阿里云的机器可以动态增加内存
解决2:内存不够,修改JVM内存 修改配置文件:/config/jvm.options
将内存从2G调整为128M。
#-Xms2G
#-Xmx2G
-Xms128M
-Xmx128M
2、问题二
[root@iZwz95j86y235aroi85ht0Z bin]# ./elasticsearch
[2018-02-22T20:14:04,870][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:用非root用户
添加用户:useradd -m 用户名 然后设置密码 passwd 用户名
3、问题三
./elasticsearch
Exception in thread "main" java.nio.file.AccessDeniedException: /usr/local/software/temp/elasticsearch-6.2.2/config/jvm.options
解决:权限不够 chmod 777 -R 当前es目录
