曾经终败给现在 2023-08-17 15:31 137阅读 0赞

安装版本 elasticsearch-5.5.2  
安装路径 /usr/local/es/

启动报错：  
/usr/local/es/elasticsearch-5.5.2/bin/  
bash ./bash ./elasticsearch

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 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 2060255232 bytes for committing reserved memory.
    # An error report file with more information is saved as:
    # /usr/local/es/elasticsearch-5.5.2/bin/hs_err_pid2353.log

解决：  
切换到配置目录下　　/usr/local/es/elasticsearch-5.5.2/config/  
打开　　jvm.options  
将 -Xms2g 改为1g　　（改1g不行就试试 改成 512m）

再次启动试一试吧。

报错：

意思是不能用root用户来启动，那我们新建一个用户来启动

继续解决这个问题

## 意思是不能用root用户来启动，那我们新建一个用户来启动
    [root@VM_0_13_centos bin]# useradd elastic
    
    ##新建elastic用户 并且把目录权限赋予给elastic 
    [root@VM_0_13_centos bin]#  chown -R elastic:elastic /usr/local/es/elasticsearch-5.5.2/
    
    ##我们切换成elastic用户，然后执行
    [root@VM_0_13_centos bin]# su elastic
    [elastic@VM_0_13_centos bin]$ sh /usr/local/es/elasticsearch-5.5.2/bin/elasticsearch

## -d 后台运行
    
    [elastic@VM_0_13_centos bin]$ sh /usr/local/es/elasticsearch-5.5.2/bin/elasticsearch -d
    
    ## 检查是否启动成功
    [elastic@VM_0_13_centos bin]$ ps -ef | grep elasticsearch

若出现这个表示成功

我们来验证下服务是否正常运行
     curl http://localhost:9200
