Linux apt-get镜像源配置

一、apt-get命令

命令解释
apt-get install一键安装软件包,与源码安装不同的是,这个指令会自动检测并安装依赖,而且用apt-get安装的包都是成熟的软件包,基本不存在安装包有严重bug或者文件缺失的情况。
apt-get install -y这里主要将的就是-y选项,添加这个选项就相当于不需要重复地确认安装
apt-get install -q即-quiet,静默安装,当然也不是完全静默,会将低等级的log信息屏蔽。
apt-get autoremove删除为了满足依赖而安装的,但现在不再需要的软件包(包括已安装包),保留配置文件;
高能警告:慎用本命令!!!
它会在你不知情的情况下,一股脑删除很多“它认为”你不再使用的软件
apt-get remove删除已安装的软件包(保留配置文件),不会删除依赖软件包,保留配置文件;
apt-get purge删除已安装的软件包(不保留配置文件),删除软件包,同时删除相应依赖软件包;
apt-get –purge remove同apt-get purge
apt-get autoclean删除为了满足某些依赖安装的,但现在不再需要的软件包;
apt的底层包是dpkg, 而dpkg安装软件包时, 会将*.deb文件放在/var/cache/apt/archives/中;
因此本命令会删除该目录下已经过期的deb;
apt-get clean删除已经安装过的的软件安装包;
即自动将/var/cache/apt/archives/下的所有deb删掉,相当于清理下载的软件安装包;

 apt-get命令需要超级用户身份,需加上sudo。
