一、绪论
【因为这篇心得是原创的，所以如果有哪处总结或者意见不足的地方，欢迎各位大神的批评和意见，共同学习，谢谢了！】
早些时候，需要在centos6.4系统中配置单机版和集群版单节点的hadoop HDFS，由于那时候一边跟老师学hadoop一边自学Linux。初学的自己懂得也不多，别人都用普通用户登录，在需要root权限时才sudo或者切换root用户进行配置，而我呢？ 从一开始就使用了root登录，在给java和hadoop配置了profile文件环境变量，等到重启之后，出现了下图的现象：进入系统用户登录界面后，原本的鼠标小指针一直都是小时钟的样子，无论怎么点击都是能移动但是指针的形状偏偏就变不回来，也无法登录。
那无法登陆了，肿么办？下意识就问老师吧，可他说他也没碰到过这种奇怪的现象。也对，但凡是规范的操作又怎么会碰到我的这种现象呢？想必极为少数吧！没有了老师的帮助，那时候我一贯的做法就是：强制关机-重启=不行，正常关机-重启=不行，之后便干脆直接放弃了整个系统，启用新系统从头开始配置HDFS。这个鼠标指针变成小时钟而无法登陆的现象，到现在前前后后碰到不下十遍，也由此令我一直耿耿于心，希望这篇心得能帮到更多与我类似困窘的人吧！
这几个月来，其实，我一直都在追寻是什么原因导致的系统用户无法登陆，以及系统的各个配置文件都有些什么作用？下面先讲该怎么恢复系统的登录先吧！
二、恢复正常登录
profile文件的错误加载而导致系统用户无法登录的现象，主要有两类：profile文件的内容配置错误、profile文件在进行vi时被挂起。如果是profile文件的内容配置错误，解决的办法：一是删除所有自定义配置的内容，但这种方法个人很不推荐；二是没有加载系统变量。至于profile文件在进行vi时被挂起，解决的办法就是恢复该文件，再删除生成的临时挂起文件。
（1）加载系统变量恢复
1、切换到字符界面。可按Ctrl+Alt+F6，由用户图形界面切换到字符界面。
2、登陆用户。这里由于用户图形界面本身就是一个应用程序，而不是Linux内核的一部分，所以即使图形用户界面完完全全地崩溃了，也是丝毫不影响我们使用字符界面进行常规的操作。这里，因为是系统的登录界面损坏，所以建议登录最高权限用户root。
3、编辑profile文件。执行如下错误，查找并修改错误配置内容：
/usr/bin/vim /etc/profile
可以看到我这里缺少了明显的系统传递参数：$PATH 。需要注意的是：如果 export PATH= 后面有多个变量值，在值与值之间需要使用英文的“ ： ”符号隔开。具体修改如下：
如果打开的profile文件中，已经存在了$PATH，那么导致图形界面无法进行用户登录的原因，很可能就是自定义部分的内容存在手动输入错误。如：缺少某个字符或者字符错误。倘若，仍然无法找到错误的根源，建议将所有自定义配置的内容进行删除。
4、保存退出后，输入一下内容进行重启，重启后便可恢复正常登录。
/usr/bin/reboot
如果不进行重启的话，也可以使用source命令让profile文件进行生效，但是不建议。因为这种方式容易导致profile文件的配置生效不完全。
（2）恢复挂起的profile文件
如果在配置profile文件内容时，中途断电或者强迫退出vim编辑，那么就会在/etc/目录下，临时生成profile.swp的隐藏文件，可以使用ll -a或者ls -a来查看是否存在.swp文件。在确保profile配置信息没有错误之后，记得删除该文件。删除的命令不再是" rm -rf profile.swp "，因为在profile文件错误加载的情况下rm命令不可直接使用，要在前面加上路径名称。具体的步骤类似上面的过程，区别在于第3步后，需要删除该隐藏文件再重启。
三、基本映射作用
没错，前面所执行的命令，如简单的重启：
/usr/bin/reboot
都在命令前加了路径名称。那么为什么需要加路径名称而不能直接使用呢？这和profile配置文件又有什么关联呢？如果每个命令都需要加前缀路径，这些前缀都相同吗？如果命令相同那么为什么执行下面的命令，会提示“No such file or directory”呢？
yang@cMaster:~]#/usr/bin/ls /etc/profile
bash: /usr/bin/ls: No such file or directory
（1）profile文件的映射类型
我们知道profile文件可进行环境变量的配置，那么对于命令的映射类型有两种：用户变量和系统变量，类似于我们win10的系统环境一样：
我们先看一下Linux系统下的$PATH都有哪些内容？使用前面修复过的系统，登录并进入命令终端，输入如下命令并查看返回信息：
yang@cMaster:~]#which $PATH
/usr/bin/which: no bin in (/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/java/jdk1.8.0_161/bin:/home/yang)
可见，“which”这个命令是属于/usr/bin/ 目录下的。至于每个常用的命令都在哪个目录下，这里先不讨论。我想说的是，我这里需要提出两个概念词，或许早有人为此下过定义，这里姑且暂用。我提出的概念是：权限比重、优先度。在权限比重方面，例如：“ /bin ”要比 “ /usr/local/bin ”权限大的多，但是“ /usr/local/bin ”的优先度级别比“ /bin ”还大。简而言之，就是用户登录系统后先使用的命令默认是 “ /usr/local/bin ”下的，当 “ /usr/local/bin ”找不到才到第二级别更高权限的“ /bin ”去找，这对于“/sbin”和“usr/sbin”一样的道理。这是对于单用户来说，如果我这里的yang用户需要root的权限，当sudo一下时，会跳出这些目录而去使用root用户“ /bin ”、 “ /usr/local/bin ”目录下的命令等等。
我们完全可以这样来假设，“ /bin ”和“/sbin”是系统环境下的指令库，而“ /usr/local/bin ”和“usr/sbin”为用户环境下的指令集。也就是，可以大胆地假设一下，对于centos6.4来说：每个Linux用户都存在一个系统环境和一个用户环境。
但其实在centos8里，“ /bin ”就是 “/usr/bin”的链接，“/sbin”也是 “/usr/sbin”的链接。
（2）profile文件的映射作用
1、root用户所定义下的profile环境内容，其他用户环境可继承性较大；
2、profile文件用于登录设置的全系统环境和启动程序。利用vi查看一下profile文件，内容如下：
# /etc/profile # System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc # It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates. pathmunge () {
case ":${PATH}:" in
*:"$1":*)
;;
*)
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
esac
} if [ -x /usr/bin/id ]; then
if [ -z "$EUID" ]; then
# ksh workaround
EUID=`id -u`
UID=`id -ru`
fi
USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
fi # Path manipulation
profile文件部分信息
将“# /etc/profile# System wide environment and startup programs, for login setup# Functions and aliases go in /etc/bashrc# It's NOT a good idea to change this file unless you know what you# are doing. It's much better to create a custom.sh shell script in# /etc/profile.d/ to make custom changes to your environment, as this# will prevent the need for merging in future updates.”粘贴到百度翻译一下：
这也恰恰说明了，为什么profile文件配置不好，会出现鼠标指针变成小时钟而无法登陆的现象。
3、profile配置文件所自定义的内容，如：export PATH= 后面必须必须跟随传递参数：$PATH 。当不配置export PATH=的值时，$PATH为隐藏属性。当export PATH=的值被配置时，$PATH的作用是将“ /bin ”、“/sbin”、“ /usr/local/bin ”和“usr/sbin”等目录下的命令进行聚集和简化路径。这也正是，为什么当profile配置文件损坏时，必须在命令前加路径名称的缘故。但是每个命令的路径名称又是什么呢？
（3）常用命令的映射目录
还记得前边说到的，在profile文件不起作用时，要删除profile挂起的临时文件，必须要在rm命令的前面加了上命令的路径名称，不然会提示No such file or directory相类似的错误。当which $PATH一下，也看到过列举了一些路径，我们逐个进去看看：
yang@cMaster:~]#ll /usr/local/bin
