volt的linux安装

1、下载

2、安装java环境

3、安装voltDB下载解压，将voltDB的bin目录配置到path

4、配置linux的内存使用

(1)关闭swap:swapoff ，如果重启后又打开了的，可以设置系统参数vm.swappiness

(2)关闭Transparent Huge Pages:

$ echo never >/sys/kernel/mm/transparent_hugepage/enabled 或者

$ echo madvise >/sys/kernel/mm/transparent_hugepage/enabled

#!/bin/bash
for f in /sys/kernel/mm/*transparent_hugepage/enabled; do
    if test -f $f; then echo never > $f; fi
done
for f in /sys/kernel/mm/*transparent_hugepage/defrag; do
    if test -f $f; then echo never > $f; fi
done

$ cat /sys/kernel/mm/transparent_hugepage/enabled
$ cat /sys/kernel/mm/transparent_hugepage/defrag

$ cat /sys/kernel/mm/redhat_transparent_hugepage/enabled
$ cat /sys/kernel/mm/redhat_transparent_hugepage/defrag

$ sysctl -w vm.overcommit_memory=1

$ sysctl -w vm.max_map_count=1048576

vm.overcommit_memory=1

vm.max_map_count=1048576
