更改 /tmp目录 的权限以授予您的用户访问权限

[root@iZuf66gcq71y5hlfv02w6aZ 50002_push]# chmod -R 777 /tmp
chmod: changing permissions of ‘/tmp’: Read-only file system

[root@iZuf66gcq71y5hlfv02w6aZ ~]# mount -o remount,rw /

1系统文件

mount -rw -o remount /

2移动硬盘或者U盘

sudo mount -o remount,rw /dev/sdc1

此时,进入文件系统,发现文件加锁,这是加权限即可

sudo chmod +777 *


1.mount 命令 [-t 文件系统] [-L 卷标名] [-o 特殊选项] 设备文件名 挂载点

-l 查询系统中已经挂载的设备,-l 会显示卷标

-a 依据配置文件/etc/fstab的内容,自动挂载

-t 系统文件,加入系统类型指定挂载类型,可以ext3,ext4, iso9660等系统文件

-L 卷标名:挂载指定分区,而不是设备文件名挂载

-o 特殊选择:可以指定挂载额外选项

atime/noatime 更新访问时间/不更新访问时间。访问分区时,是否更新文件的访问时间,默认更新

async/sync 异步/同步 默认异步

auto/noauto 自动/手动 mount -a命令执行时,是否会自动安装/etc/fstab 文件内容挂载,默认自动

defaults 定义默认值,相当于rw、suid、dev、exec、auto、nouser、async这七个选择

exec/noexec 执行/不执行,设定师傅允许文件系统中执行可执行文件,默认是exec允许

remount 重新挂载已经挂载的文件系统,一般用于修改特殊权限

rw/ro 读写/只读,文件系统挂载时,是否有读写的权限,默认rw

suid/nosuid 具有/不具有SUID权限,设定文件系统是否具有SUID权限,默认具有

user/nouser 允许/不允许普通用户挂载,设定文件系统是否允许普通用户挂载,默认不允许,只有root可以挂载分区

usrquata 写入代表文件系统支持用户磁盘配额,默认不支持

grpquata 写入代表文件系统支持组磁盘配额,默认不允许

eg: mount -o remount,noexec /home 让 /home目录下不能执行可执行文件



java.io.IOException: java.io.FileNotFoundException: /tmp/tomcat.11513951024260551319.8252/work/Tomca

可能是多线程的问题

Unable to create tempDir. java.io.tmpdir is set to /tmp 结构需要清理 java unable to access jarfile

1、可能是执行路径有误错误  修改后,需使用绝对路径  2、决解1后,还报以下错误,就是你的安装的JDK与jar包中的JDK不是同一版本。idea中有自带的JDK与我们安装的JDK版本有差别Exception in thread "main" java.lang.UnsupportedClassVersionError: com/company/Spring
