12、RHCSA试题EX200详解（十二）配置 autofs题目要求：配置 autofsl 配置 autofs，实现用户 ldapuser0 登录后有家目录 /home/guests/ldapuser0l 家目录在 classroom.example.com 上被 NFS 共享为 /home/guests/ldapuser0l 并且要求用户登录后，具有读写权限l 要求使用 NFS3 挂载知识点小贴士：

showmount命令用于查询NFS服务器的相关信息

# showmount --help

　　Usage： showmount ［-adehv］

　　［--all］ ［--directories］ ［--exports］

　　［--no-headers］ ［--help］ ［--version］ ［host］

　　-a或--all

　　以 host:dir 这样的格式来显示客户主机名和挂载点目录。

　　-d或--directories

　　仅显示被客户挂载的目录名。

　　-e或--exports

　　显示NFS服务器的输出清单。

　　-h或--help

　　显示帮助信息。

　　-v或--version

　　显示版本信。

　　--no-headers

　　禁止输出描述头部信息。

　　显示NFS客户端信息

getent 用来查看系统的数据库中的相关记录

用法： getent [选项...] 数据库 [键 ...]

Get entries from administrative database.

-s, --service=CONFIG 要使用的服务配置

-?, --help 给出该系统求助列表

--usage 给出简要的用法信息

-V, --version 打印程序版本号

长选项的强制或可选参数对对应的短选项也是强制或可选的。

支持的数据库：

ahosts ahostsv4 ahostsv6 aliases ethers group gshadow hosts netgroup

networks passwd protocols rpc services shadow

15、RHCSA试题EX200详解（十五）查找文件题目要求：查找文件l 找出 harry 用户拥有的文件，拷贝到目录 /opt/finddir解题步骤：

（1）查看目录状态，无：

[root@desktop0 ~]# ls /opt/finddir

ls: cannot access /opt/finddir: No such file or directory

（2）创建目录：

[root@desktop0 ~]# mkdir /opt/finddir

（3）按题意拷贝harry用户资料到该目录：

[root@desktop0 ~]# find / -user harry -exec cp -a {} /opt/finddir \;

find: ‘/proc/4337/task/4337/fd/6’: No such file or directory

find: ‘/proc/4337/task/4337/fdinfo/6’: No such file or directory

find: ‘/proc/4337/fd/6’: No such file or directory

find: ‘/proc/4337/fdinfo/6’: No such file or directory

cp: cannot overwrite non-directory ‘/opt/finddir/harry’ with directory ‘/home/harry’

cp: ‘/opt/finddir/harry’ and ‘/opt/finddir/harry’ are the same file

cp: ‘/opt/finddir/.bash_logout’ and ‘/opt/finddir/.bash_logout’ are the same file

cp: ‘/opt/finddir/.bash_profile’ and ‘/opt/finddir/.bash_profile’ are the same file

cp: ‘/opt/finddir/.bashrc’ and ‘/opt/finddir/.bashrc’ are the same file

cp: ‘/opt/finddir/.mozilla’ and ‘/opt/finddir/.mozilla’ are the same file

cp: ‘/opt/finddir/extensions’ and ‘/opt/finddir/extensions’ are the same file

cp: ‘/opt/finddir/plugins’ and ‘/opt/finddir/plugins’ are the same file

cp: ‘/opt/finddir/.config’ and ‘/opt/finddir/.config’ are the same file

cp: ‘/opt/finddir/gnome-initial-setup-done’ and ‘/opt/finddir/gnome-initial-setup-done’ are the same file

cp: ‘/opt/finddir/monitors.xml’ and ‘/opt/finddir/monitors.xml’ are the same file

cp: ‘/opt/finddir/abrt’ and ‘/opt/finddir/abrt’ are the same file

cp: ‘/opt/finddir/.cache’ and ‘/opt/finddir/.cache’ are the same file

cp: ‘/opt/finddir/lastnotification’ and ‘/opt/finddir/lastnotification’ are the same file

16、RHCSA试题EX200详解（十六）过滤文件内容题目要求：过滤文件内容l 从文件 /usr/share/dict/words 中找出包含 seismic 的行，写入到文件 /root/lines.txt 中，要求顺序与原文件中一致，并没有空行知识点小贴士：

grep -v '^$' ：命令的作用是过滤空白符

linux中“grep -v '^$' /etc/rsyslog.conf | grep -v '^#'”是什么意思？

1、-v是grep排除的参数，例如查询除了包含ABC的行，例如cat a.txt|grep -v 'ABC'

2、^代表行首，$代表行尾。 ^$是空行的意思

3、^#表示首字母为#的行，linux里的文件，#号开头一般都是注释内容

4、grep -v '^$' /etc/rsyslog.conf | grep -v '^#'

查询/etc/rsyslog.conf文件，但是不包含空行和注释行。

解题步骤：

（1）执行命令：

[root@desktop0 ~]# grep seismic /usr/share/dict/words | grep -v ^$ > /root/lines.txt

（2）验证：

[root@desktop0 ~]# cat /root/lines.txt

seismic

httpd seismic

http seismic

[root@desktop0 ~]# grep seismic /usr/share/dict/words

seismic

httpd seismic

http seismic

17、RHCSA试题EX200详解（十七）创建一个归档题目要求：创建一个归档l 将 /usr/local 中的所有文件归档到 /root/backup.tar.bz2, 要求压缩类型为 gzip知识点小贴士：

Linux下的tar压缩解压缩命令详解

tar

-c: 建立压缩档案

-x：解压

-t：查看内容

-r：向压缩归档文件末尾追加文件

-u：更新原压缩包中的文件

这五个是独立的命令，压缩解压都要用到其中一个，可以和别的命令连用但只能用其中一个。下面的参数是根据需要在压缩或解压档案时可选的。

-z：有gzip属性的

-j：有bz2属性的

-Z：有compress属性的

-v：显示所有过程

-O：将文件解开到标准输出

下面的参数-f是必须的

-f: 使用档案名字，切记，这个参数是最后一个参数，后面只能接档案名。

# tar -cf all.tar *.jpg

这条命令是将所有.jpg的文件打成一个名为all.tar的包。-c是表示产生新的包，-f指定包的文件名。

# tar -rf all.tar *.gif

这条命令是将所有.gif的文件增加到all.tar的包里面去。-r是表示增加文件的意思。

# tar -uf all.tar logo.gif

这条命令是更新原来tar包all.tar中logo.gif文件，-u是表示更新文件的意思。

# tar -tf all.tar

这条命令是列出all.tar包中所有文件，-t是列出文件的意思

# tar -xf all.tar

这条命令是解出all.tar包中所有文件，-t是解开的意思

解题步骤：
