linux 账号管理 安装软件

应用程序与系统命令的关系

文件位置

               系统命令：一般在/bin和/sbin目录中，或为shell内部指令

               应用程序：通常在/usr/bin和/usr/sbin目录中

主要用途

              系统命令：完成对系统的基本管理工作

              应用程序：完成相对独立的其他辅助任务

/etc  存放配置文件

/var/log 存放日志文件

/usr/share/doc 应用程序文档

rpm软件包  扩展名为 ".rpm"  方便管理 

deb软件包  扩展名为".deb"

源代码包  "tar.gz" ,".tar.bz2" 通用性强，灵活性强，安装麻烦

rpm -e vsftpd 先卸载

rpm --import RPM-GPG-KEY-redhat-release导入密钥，然后再进行安装

当安装软件包时，系统会使用导入的key，对软件包进行验证，验证软件包的完整性

rpm --initdb 重新修复 rpm 数据库

yum 解决软件包的依赖关系

确认源代码编译环境

需安装支持C/C++程序语言的编译器

[root@localhost tmp]# rpm -qa |grep ^gcc*
gcc-objc-4.1.2-14.el5
gcc-c++-4.1.2-14.el5
gcc-4.1.2-14.el5

[root@localhost tmp]# 

gcc -v 查看gcc的版本号

源码包的安装步骤

1、tar包解压缩

      解压并释放源代码包到指定目录

     解包后的源代码文件位置/usr/src/软件名-版本号

2、./configuration

      设置安装目录，安装模块等选项

3、make编译

      生成可执行的二进制文件

4、make install 

     复制二进制文件到系统，配置应用环境

yum 服务器配置

YUM  Yellodog Updater Modified

      可以自动解决依赖关系

     所有软件包由集中地YUM软件仓库提供

软件仓库的提供方式

      FTP服务：ftp://

      HTTP服务:http://

      本地服务:file:///

RPM软件包的来源

      mkdir  /var/ftp/rhel6

     cp -rf /misc/cd/*  /var/ftp/rhel6

     rpm -ivh vsftpd

     [root@localhost tmp]# chkconfig --level 35 vsftpd on 

     vsftpd服务在运行级别为3或者5时自动启动

     service vsftpd start

     service vsftpd status

     service vsftpd restart

     service vsftpd stop

mount /dev/cdrom /mnt //挂载即映射，将光盘中的内容映射到对应文件中，不占用实际空间

chkconfig --level 35 vsftpd on  将服务设置为开机自动启动

cp -rf /mnt/* /var/ftp

在软件仓库中加入非官方RPM包

包括存在依赖关系的所有RPM包

使用createrepo工具建立仓库数据文件

cd /var/ftp/other

createrepo -g /misc/cd/repodata/repomd.xml ./生成仓库数据文件

ls -lh repodata

yum install 软件包

yum groupinstall 包组名

yum update 软件包

yum groupupdate 包组名

yum -y install vsftpd

yum remove 软件名

yum groupremove 包组名

yum grouperase 包组名

不建议使用yum卸载软件包，会卸载软件包的所有依赖包，影响其他软件包的使用

推荐使用rpm -e 进行卸载

service NetworkManager stop

chkconfig --level 35 NetworkManager off

linux中ip改变不会自动生效需要重启网卡

当改变网卡自动回让ip地址生效，此服务作用，但有Bug，故禁用

vim /etc/sysconfig/network-scripts/ifcfg-eth0

NM_CONTROLLED=no 网卡是否受NetworkManager 服务控制，默认为yes

USERCTL=no 普通用户是否能修改

service network restart 重启网络服务

ip addr show

scp [email protected]:/etc/yum.repos.d/rhel.repo

ftp默认宿主目录为/var/ftp

yum-plugin-verify 允许yum检查软件包的完整性

yum-plugin-changelog 使用yum查看软件包changelog 

yum -y install yum-plugin-changelog
