Linux部署Elasticsearch（二）：启动Elasticsearch不成功的几种原因

启动Elasticsearch时，报了以下错误

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit\_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12)  
![20190301105134824.png][]

由于elasticsearch5.0默认分配jvm空间大小为2g，修改jvm空间分配  
vim /opt/elasticsearch-5.0.0/config/jvm.options

将如下代码

改成

![20190301105444233.png][]

即是将jvm空间大小为2g改为512m

保存退出，启动报了如下错误：

一：main ERROR Unable to create file /opt/elasticsearch-5.0.0/logs/my-application.log java.io.IOException: Permission denied

创建不了logs、data文件夹，权限不足

看下elasticsearch的部署文件（我这是elasticsearch-5.0.0）的权限是谁的

![20190228104226496.png][]

权限是root：root的，启动时不能用root权限启动的，我在上一篇安装的时候建了elastic:elastic的组和用户，将elasticsearch-5.0.0文件夹添加到elastic权限中

chown -R elastic:elastic elasticsearch-5.0.0

命令解析：

chown \[选项\]... \[所有者\]\[:\[组\]\] 文件...

通过chown改变文件的拥有者和群组。在更改文件的所有者或所属群组时，可以使用用户名称和用户识别码设置。普通用户不能将自己的文件改变成其他的拥有者。其操作权限一般为管理员。

命令参数：

必要参数:

\-c 显示更改的部分的信息

\-f 忽略错误信息

\-h 修复符号链接

\-R 处理指定目录以及其子目录下的所有文件

\-v 显示详细的处理信息

\-deference 作用于符号链接的指向，而不是链接文件本身

选择参数:

\--reference=<目录或文件> 把指定的目录/文件作为参考，把操作的文件/目录设置成参考文件/目录相同拥有者和群组

\--from=<当前用户：当前群组> 只有当前用户和群组跟指定的用户和群组相同时才进行改变

\--help 显示帮助信息

\--version 显示版本信

以上chown知识参考自博文[https://blog.csdn.net/qq\_32331073/article/details/76460192][https_blog.csdn.net_qq_32331073_article_details_76460192]

再看权限

二：main ERROR Unable to invoke factory method in class class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile. java.lang.reflect.InvocationTargetException

安装log4j包

yum  install -y log4j\*
