为了达到一个目的，而进行的命令组合与分析
新装centos6.5-minimal所必须要做的初始动作，修改一些默认的东西
vi /boot/grub/grub.conf在内核行后加入vga=ask或788就启用了framebuffer cp /etc/DIR_COLORS ~/.dir_colors 控制台设置白底黑字 setterm -foreground black -background white -store
关闭ipv6支持
centos 6.5min-64下是/etc/modprobe.d/dist.conf中修改，加入以下两行就关闭了内核ipv6支持，但不能关闭其它程序对ipv6的支持，重启机器生效
alias net-pf-10 off
alias ipv6 off

目的：分析出uid与euid 一。linux系统中每个进程都有2个ID，分别为用户ID（uid）和有效用户ID（euid），UID一般表示进程的创建者（属于哪个用户创建），而EUID表示进程对于文件和资源的访问权限（具备等同于哪个用户的权限）。C语言中，可以通过函数getuid()和geteuid（）来获得进程的两个ID值。 当一个用户登陆系统时，系统会将UID和EUID都赋值为/etc/passwd文件中的UID，一般情况下2个ID是相同的，但是某些情况下会出现2个ID不同的情况。gid和egid同理。 新建用户 [root@250-shiyan ~]# useradd test2 [root@250-shiyan ~]# passwd test2 用新用户去登录 [test2@250-shiyan ~]$ id uid=503(test2) gid=503(test2) groups=503(test2) 下面一段C代码将解释区别："printid.c" [test2@250-shiyan ~]$ vi printid.c #include <stdlib.h> #include <stdio.h> #include <unistd.h> #include <sys/types.h> int main(void) { printf(" UID = %d ", getuid()); printf(" EUID = %d ", geteuid()); printf(" GID = %d ", getgid()); printf(" EGID = %d ", getegid()); return EXIT_SUCCESS; } [test2@250-shiyan ~]$ gcc -o printid printid.c [test2@250-shiyan ~]$ id uid=503(test2) gid=503(test2) groups=503(test2) [test2@250-shiyan ~]$ ./printid UID = 503 EUID = 503 GID = 503 EGID = 503 看看/etc/passwd里uid和gid： [test2@250-shiyan ~]$ cat /etc/passwd|grep "<test2>"|awk -F ':' '{print "uid:"$3,"tgid:"$4}' uid:503 tgid:503 以上是相同的例子。 下面演示uid和euid不同的例子。 首先，修改一下文件属性，setuid或setgid [test2@250-shiyan ~]$ chmod u+s printid #这样一来，文件在执行阶段具有文件所有者的权限。 还可以再补充一个： [test2@250-shiyan ~]$ chmod g+s printid #这样一来，文件在执行阶段具有文件所属组的权限。 其次，变成其他用户，再来试验一下，比如变成root； [test2@250-shiyan ~]$ su Password: [root@250-shiyan test2]# ll total 12 -rwsrwxr-x 1 test2 test2 7055 Mar 24 10:31 printid -rw-rw-r-- 1 test2 test2 284 Mar 24 10:30 printid.c [root@250-shiyan test2]# ./printid UID = 0 EUID = 503 GID = 0 EGID = 0 这时uid虽是0，但EUID却是503，即文件所有者的权限 Linux系统就是使用setuid来解决这个矛盾的问题：如果一个程序被设置了setuid位，那么它无论被哪个用户启用，都会具备程序所有者的权限。而passwd程序的所有者是root用户，passwd的权限如下所示，那么任何用户执行该程序，程序的EUID就会变成root用户的EUID,而不是执行该程序的UID。 可以使用chmod u+s 或chmod g+s来设置二进制的可执行文件的euid。setuid只能对二进制的可执行设置。
