篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Linux课程第九天学习笔记相关的知识,希望对你有一定的参考价值。

####################
"which"和"whereis"的使用:
[[email protected] Desktop]# which ls
alias ls=‘ls --color=auto‘
    /usr/bin/ls
[[email protected] Desktop]# whereis ls
ls: /usr/bin/ls /usr/share/man/man1/ls.1.gz /usr/share/man/man1p/ls.1p.gz

百度".bash_profile"的作用:每个用户都可使用该文件输入专用于自己使用的shell信息,当用户登录时,该文件仅仅执行一次!默认情况下,他设置一些环境变量,执行用户的.bashrc文件。
/etc/skel/.bash_profile        ##默认配置
/root/.bash_profile        ##root用户生效
/home/kiosk/.bash_profile    ##普通用户生效
####################

####################
#### 13.软件安装    ####
####################

软件安装的过程就是文件新建的过程

####################1.软件名称的识别####################
abrt-addon-ccpp-2.1.11-19.el7.x86_64.rpm
abrt-addon-ccpp        ##软件名称
2.1.11-19        ##软件版本
el7            ##软件适用系统版本
x86_64            ##软件架构(64位)
rpm            ##适用于redhat操作系统(包括CentOS等类红帽操作系统)

注意:软件的名字和软件包的名字是不一样的,软件包的名字包含软件的名字

####################
图形安装和卸载:
比如"firefox-31.4.0-1.el7_0.x86_64.rpm"和"flash-plugin-11.2.202.457-release.x86_64"
安装:双击进行安装
卸载:Applications-->System Tools-->Software-->搜索软件名字-->选中软件-->取消打钩|点击"remove package"-->apply

[[email protected] Desktop]# mount /iso/rhel-server-7.1-x86_64-dvd.iso /mnt
mount: /dev/loop3 is write-protected, mounting read-only
[[email protected] Desktop]# ls /mnt/Packages/ | wc -l
4372
共有4372个软件包,而安装一个带图形的Linux系统实际只需要1200多个软件包

去哪里下载软件?
1.百度"RPM Search"
其中"RPM Search CentOS"里的软件和RedHat通用
2.百度"SourceForge"
这个里面的软件更全
####################

####################2.如何安装软件####################
1.rpm
rpm    -i    name.rpm        ##安装
    -v    name.rpm        ##显示安装进度
    -h    name.rpm        ##指定加密方式
    -e    name            ##卸载
    -ql    name            ##查询软件生成的文件
    -qlp    name.rpm        ##查询软件包安装后会生成什么文件
    -qa                ##查询系统中安装的所有软件名称
    -qa | gerp name            ##查询软件是否已安装
    -q    name            ##(同上)
    -qp    name.rpm        ##查询软件安装包安装后的名字
    -qf    filename        ##查询filename属于哪个安装包
    -ivh    name.rpm --force    ##强制安装
    -qi    name            ##查看软件信息
    -Kv    name.rpm        ##检测软件包是否被篡改
    -qp    name.rpm --scripts    ##检测软件在安装或卸载过程中执行的动作
    -ivh    name.rpm --nodeps    ##不检测依赖性直接安装(装上使用不了,没用处)

百度“GPL协议”:
简而言之,GPL协议就是一个开放源代码协议。软件的初始开发者使用了GPL协议并公开软件的源程序后,后续使用该软件源程序开发软件者亦应当根据GPL协议把自己编写的源程序进行公开。GPL协议要求的关键在于开放源程序,但并不排斥软件作者向用户收费。

####################2.yum####################
yum是上层软件管理工具,最重要的功能是可以解决软件的依赖关系
yum能够投入使用的前提是必须要有yum源,以及配置源的指向文件

<server源端>
1.找到与本机系统版本匹配的iso镜像文件
rhel-server-7.1-x86_64-dvd.iso

2.把rhel-server-7.1-x86_64-dvd.iso挂载到/mnt以便访问镜像中的文件
mount rhel-server-7.1-x86_64-dvd.iso /mnt

3.配置本机yum源指向
rm -fr /etc/yum.repos.d/*
vim /etc/yum.repos.d/yum.repo
----------------------------------------------------------------------
[Server]
name=rhel7.1
baseurl=file:///mnt
gpgcheck=0
:wq
----------------------------------------------------------------------
yum clean all

4.安装资源共享服务
yum install httpd -y
systemctl stop firewalld
systemctl disable firewalld
systemctl start httpd
systemctl enable httpd

5.建立共享目录,并挂载镜像文件到共享目录上
mkdir /var/www/html/rhel7.1
umount /mnt
mount rhel-server-7.1-x86_64-dvd.iso /var/www/html/rhel7.1

6.测试
在浏览器中输入:http://本机ip/rhel7.1
可以看到镜像中的内容

7.修改本机yum源指向
vim /etc/yum.repos.d/yum.repo
----------------------------------------------------------------------
[Server]
name=rhel7.1
baseurl=file:///var/www/html/rhel7.1
gpgcheck=0
:wq
----------------------------------------------------------------------
yum clean all

8.开机自动挂载iso
vim /etc/rc.d/rc.local
----------------------------------------------------------------------
mount rhel-server-7.1-x86_64-dvd.iso /var/www/html/rhel7.1
:wq
----------------------------------------------------------------------
chmod u+x /etc/rc.d/rc.local
重启后,使用"df"命令查看,或者"mount"直接回车查看

####################
"/etc/rc.d/rc.local"重启后系统自动执行的一个脚本

把mount命令写到".bash_profile"和"rc.local"的区别:
如果删除镜像,写到"bash_profile"下,会让系统启不起来;而写到"rc.local"下,系统可以启起来
####################

9.第三方软件仓库的搭建
把所有的rpm软件包放到一个目录中,这个目录中只能存在rpm文件
createrepo -v /rpm存放目录
vim /etc/yum.repos.d/xxx.repo
[Software]
name=software
baseurl=file:///rpm存放目录
gpgcheck=0

<client指向端>
vim /etc/yum.repos.d/xxx.repo        ##仓库指向文件位置
[xxx]                    ##自定义软件仓库名称
name=xxx                ##自定义软件仓库描述
baseurl=ftp:// | http:// | file://    ##仓库位置
gpgcheck=0                ##不检测gpgkey,gpgkey表示软件的出品logo

"gpgcheck=0":表示安装第三方软件
"gpgcheck=1":表示拒绝安装第三方软件

如果使用"gpgcheck=1",那么就要指定"gpgkey"的位置
比如:
gpgcheck=1
gpgkey=http://172.25.50.250/rhel7.1/RPM-GPG-KEY-redhat-release

"enabled=0":表示忽略本安装源

例子:
vim /etc/yum.repos.d/yum.repo
----------------------------------------------------------------------
[Server]
name=rhel7.1
baseurl=ftp://172.25.0.254/pub/rhel7.1
gpgcheck=0
:wq
----------------------------------------------------------------------
yum clean all            ##清空yum缓存,识别新配置

执行"yum install 软件名"命令会自动识别新配置
"yum clean all"的主要作用是清空yum缓存

yum install lftp -y        ##安装软件"lftp","-y"表示直接安装

如果不加参数"-y",安装过程中提示:
Is this ok [y/d/N]:
y    ##表示安装
d    ##表示下载
n    ##表示什么都不做
