安装es过程遇到的问题

1、无法将文件复制到虚拟机,提示

环境:虚拟机centos7
问题:新安装的centos7无法复制文件(从物理机到虚拟机)
报错提示:Error when getting information for file “//tmp/VMwareDnD/....
1)运行下面命令:

systemctl start run-vmblock\\x2dfuse.mount
systemctl enable run-vmblock\\x2dfuse.mount
yum install open-vm-tools-desktop -y
yum reinstall open-vm-tools -y

2)重启虚拟机

 

2、进入bin目录下,如果修改了host,启动elastic报错

[3]: max number of threads [3756] for user [was] is too low, increase to at least [4096]

1)切换到root用户,备份原有配置,这个解决的是问题2

[root@localhost elasticsearch-6.1.2]# cd /etc
[root@localhost etc]# cp sysctl.conf sysctl.conf.bak

编辑sysctl.conf,增加如下内容

# elasticsearch config start
vm.max_map_count=262144
# elasticsearch config end

2)先做一个配置备份这个解决问题1和3

[root@localhost elasticsearch-6.1.2]# cd /etc/security/
[root@localhost security]# cp limits.conf limits.conf.bak

然后编辑limits.conf增加如下配置:
[root@localhost etc]# vim sysctl.conf

# elasticsearch config start
* soft nofile 65535
* hard nofile 65535
* soft nproc 2048
* hard nproc 4096
# elasticsearch config end

最后重启虚拟机。
