RedHat系Linux软件包管理
一、RPM包的管理
rpm软件包的一个例子：
sudo-1.7.4p5-11.el6.i686.rpm
其中包括软件名（sudo），版本号（1.7.4p5），发行号（11.el6）和硬件平台（i686）
1、卸载
[root@localhost ~]# rpm -e sudo
如果其它软件包有依赖关系，卸载时会产生提示信息，可以使用--nodeps强行卸载
[root@localhost ~]# rpm -e --nodeps samba
2、安装
光盘里面带有的软件包，可以直接从光盘安装
1）挂载光盘
[root@localhost ~]# mkdir /mnt/cdrom [root@localhost ~]# mount /dev/cdrom /mnt/cdrom mount: block device /dev/sr0 is write-protected, mounting read-only [root@localhost ~]#
2）rpm的安装包都放在Packages目录中
[root@localhost ~]# cd /mnt/cdrom [root@localhost cdrom]# ls CentOS_BuildTag Packages RPM-GPG-KEY-CentOS-Security-6 EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6 GPL repodata TRANS.TBL images RPM-GPG-KEY-CentOS-6 isolinux RPM-GPG-KEY-CentOS-Debug-6 [root@localhost cdrom]#
3）找到sudo的安装包
[root@localhost cdrom]# cd Packages [root@localhost Packages]# ls | grep sudo sudo-1.7.4p5-11.el6.i686.rpm [root@localhost Packages]#
4）执行安装
[root@localhost Packages]# rpm -ivh sudo-1.7.4p5-11.el6.i686.rpm warning: sudo-1.7.4p5-11.el6.i686.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] 1:sudo ########################################### [100%] [root@localhost Packages]#
5）查询软件包是否已安装
[root@localhost Packages]# rpm -q sudo sudo-1.7.4p5-11.el6.i686 [root@localhost Packages]#
没有安装的会给出提示
[root@localhost ~]# rpm -q samba package samba is not installed [root@localhost ~]#
6）--excludedocs 不安装软件包中的文档文件
[root@localhost Packages]# rpm -ivh --excludedocs sudo-1.7.4p5-11.el6.i686.rpm
7）--prefix PATH 将软件包安装到由PATH指定的路径下
[root@localhost Packages]# rpm -ivh --prefix=/usr/local/sudo sudo-1.7.4p5-11.el6.i686.rpm
不过指定rpm包的安装路径意义不大，rpm一般都不允许改变安装目录，rpm包在设计的时候就已经指定好相应的安装目录了
8）--test 只对安装进行测试，并不实际安装
[root@localhost Packages]# rpm -ivh --test sudo-1.7.4p5-11.el6.i686.rpm
9）软件包已被安装
[root@localhost Packages]# rpm -ivh sudo-1.7.4p5-11.el6.i686.rpm warning: sudo-1.7.4p5-11.el6.i686.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] package sudo-1.7.4p5-11.el6.i686 is already installed [root@localhost Packages]#
如果要覆盖安装该软件包，可以使用--replacepkgs选项
[root@localhost Packages]# rpm -ivh --replacepkgs sudo-1.7.4p5-11.el6.i686.rpm warning: sudo-1.7.4p5-11.el6.i686.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] 1:sudo ########################################### [100%] [root@localhost Packages]#
10）文件冲突
如果要安装的软件包中有一个文件已在安装其它软件包是安装了，就会出现文件冲突，可以使用--replacefiles选项
[root@localhost Packages]# rpm -ivh --replacefiles sudo-1.7.4p5-11.el6.i686.rpm
11）未解决依赖关系
RPM软件包可能依赖于其它软件包，在安装了依赖的软件包之后才能安装该软件包。强制安装使用--nodeps选项，如果依赖包没安装，强制安装的软件一般用不了。
3、升级
比如升级到 sudo-1.8.0p5-11.el6.i686.rpm
[root@localhost Packages]# rpm -Uvh sudo-1.8.0p5-11.el6.i686.rpm
二、YUM包管理
应用yum包的好处：
自动解决软件包依赖关系
方便的软件包升级
1、安装 yum install （需要网络访问）
[root@bogon ~]# yum install sudo Loaded plugins: fastestmirror, security Determining fastest mirrors * base: mirror.neu.edu.cn * extras: mirror.neu.edu.cn * updates: mirror.neu.edu.cn base | 3.7 kB 00:00 base/primary_db | 3.5 MB 00:07 extras | 3.5 kB 00:00 extras/primary_db | 24 kB 00:00 updates | 3.5 kB 00:00 updates/primary_db | 3.8 MB 00:08 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package sudo.i686 0:1.7.4p5-13.el6_3 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: sudo i686 1.7.4p5-13.el6_3 updates 419 k Transaction Summary ================================================================================ Install 1 Package(s) Total download size: 419 k Installed size: 1.0 M Is this ok [y/N]: y Downloading Packages: sudo-1.7.4p5-13.el6_3.i686.rpm | 419 kB 00:01 warning: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Importing GPG key 0xC105B9DE: Userid : CentOS-6 Key (CentOS 6 Official Signing Key) <centos-6-key@centos.org> Package: centos-release-6-3.el6.centos.9.i686 (@anaconda-CentOS-201207051201.i386/6.3) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Is this ok [y/N]: y Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: RPMDB altered outside of yum.

2、检测升级 yum check-update
[root@bogon ~]# yum check-update sudo Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: mirror.neu.edu.cn * extras: mirror.neu.edu.cn * updates: mirror.neu.edu.cn [root@bogon ~]#
3、升级 yum update
[root@bogon ~]# yum update sudo Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: mirror.neu.edu.cn * extras: mirror.neu.edu.cn * updates: mirror.neu.edu.cn Setting up Update Process No Packages marked for Update [root@bogon ~]#
4、软件包查询yum list
[root@bogon ~]# yum list | grep sudo sudo.i686 1.7.4p5-13.el6_3 @updates [root@bogon ~]#
5、软件包信息yum info
[root@bogon ~]# yum info sudo Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: mirror.neu.edu.cn * extras: mirror.neu.edu.cn * updates: mirror.neu.edu.cn Installed Packages Name : sudo Arch : i686 Version : 1.7.4p5 Release : 13.el6_3 Size : 1.0 M Repo : installed From repo : updates Summary : Allows restricted root access for specified users URL : http://www.courtesan.com/sudo/ License : ISC Description : Sudo (superuser do) allows a system administrator to give certain : users (or groups of users) the ability to run some (or all) : commands as root while logging all commands and arguments.

Features include: the ability to restrict what commands a : user may run on a per-host basis, copious logging of each command : (providing a clear audit trail of who did what), a configurable : timeout of the sudo command, and the ability to use the same : configuration file (sudoers) on many different machines. [root@bogon ~]#
6、卸载 yum remove
[root@bogon ~]# yum remove sudo Loaded plugins: fastestmirror, security Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package sudo.i686 0:1.7.4p5-13.el6_3 will be erased --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Removing: sudo i686 1.7.4p5-13.el6_3 @updates 1.0 M Transaction Summary ================================================================================ Remove 1 Package(s) Installed size: 1.0 M Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Erasing : sudo-1.7.4p5-13.el6_3.i686 1/1 Verifying : sudo-1.7.4p5-13.el6_3.i686 1/1 Removed: sudo.i686 0:1.7.4p5-13.el6_3 Complete! [root@bogon ~]#
7、帮助yum -help、man yum
三、RPM查询应用案例
1、查询文件隶属的软件包 rpm -qf
[root@bogon ~]# rpm -qf /etc/services setup-2.8.14-16.el6.noarch [root@bogon ~]# rpm -qf /bin/ls coreutils-8.4-19.el6.i686 [root@bogon ~]#
2、查询软件包信息 rpm -qi、rpm -qip（查询还未安装的软件包）
[root@bogon ~]# rpm -qi sudo Name : sudo Relocations: (not relocatable) Version : 1.7.4p5 Vendor: CentOS Release : 13.el6_3 Build Date: 2012年08月06日 星期一 22时43分51秒 Install Date: 2012年12月15日 星期六 15时24分40秒 Build Host: c6b7.bsys.dev.centos.org Group : Applications/System Source RPM: sudo-1.7.4p5-13.el6_3.src.rpm Size : 1078427 License: ISC Signature : RSA/SHA1, 2012年08月06日 星期一 23时31分02秒, Key ID 0946fca2c105b9de Packager : CentOS BuildSystem <http://bugs.centos.org> URL : http://www.courtesan.com/sudo/ Summary : Allows restricted root access for specified users Description : Sudo (superuser do) allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis. It is not a replacement for the shell. Features include: the ability to restrict what commands a user may run on a per-host basis, copious logging of each command (providing a clear audit trail of who did what), a configurable timeout of the sudo command, and the ability to use the same configuration file (sudoers) on many different machines. [root@bogon ~]#
3、查询软件包安装文件rpm -ql、rpm -qlp（查询还未安装的软件包）
[root@bogon ~]# rpm -ql sudo /etc/pam.d/sudo /etc/pam.d/sudo-i /etc/sudo-ldap.conf /etc/sudoers /etc/sudoers.d /usr/bin/sudo /usr/bin/sudoedit /usr/bin/sudoreplay /usr/libexec/sesh /usr/libexec/sudo_noexec.so /usr/sbin/visudo /usr/share/doc/sudo-1.7.4p5 /usr/share/doc/sudo-1.7.4p5/ChangeLog /usr/share/doc/sudo-1.7.4p5/HISTORY /usr/share/doc/sudo-1.7.4p5/LICENSE /usr/share/doc/sudo-1.7.4p5/NEWS /usr/share/doc/sudo-1.7.4p5/README /usr/share/doc/sudo-1.7.4p5/README.LDAP /usr/share/doc/sudo-1.7.4p5/TROUBLESHOOTING /usr/share/doc/sudo-1.7.4p5/UPGRADE /usr/share/doc/sudo-1.7.4p5/sample.pam /usr/share/doc/sudo-1.7.4p5/sample.sudoers /usr/share/doc/sudo-1.7.4p5/sample.syslog.conf /usr/share/doc/sudo-1.7.4p5/schema.ActiveDirectory /usr/share/doc/sudo-1.7.4p5/schema.OpenLDAP /usr/share/doc/sudo-1.7.4p5/schema.iPlanet /usr/share/doc/sudo-1.7.4p5/sudoers2ldif /usr/share/man/man5/sudoers.5.gz /usr/share/man/man5/sudoers.ldap.5.gz /usr/share/man/man8/sudo.8.gz /usr/share/man/man8/sudoedit.8.gz /usr/share/man/man8/sudoreplay.8.gz /usr/share/man/man8/visudo.8.gz /var/db/sudo [root@bogon ~]#
4、查询软件包帮助文档rpm -qd
[root@bogon ~]# rpm -qd sudo /usr/share/doc/sudo-1.7.4p5/ChangeLog /usr/share/doc/sudo-1.7.4p5/HISTORY /usr/share/doc/sudo-1.7.4p5/LICENSE /usr/share/doc/sudo-1.7.4p5/NEWS /usr/share/doc/sudo-1.7.4p5/README /usr/share/doc/sudo-1.7.4p5/README.LDAP /usr/share/doc/sudo-1.7.4p5/TROUBLESHOOTING /usr/share/doc/sudo-1.7.4p5/UPGRADE /usr/share/doc/sudo-1.7.4p5/sample.pam /usr/share/doc/sudo-1.7.4p5/sample.sudoers /usr/share/doc/sudo-1.7.4p5/sample.syslog.conf /usr/share/doc/sudo-1.7.4p5/schema.ActiveDirectory /usr/share/doc/sudo-1.7.4p5/schema.OpenLDAP /usr/share/doc/sudo-1.7.4p5/schema.iPlanet /usr/share/doc/sudo-1.7.4p5/sudoers2ldif /usr/share/man/man5/sudoers.5.gz /usr/share/man/man5/sudoers.ldap.5.gz /usr/share/man/man8/sudo.8.gz /usr/share/man/man8/sudoedit.8.gz /usr/share/man/man8/sudoreplay.8.gz /usr/share/man/man8/visudo.8.gz [root@bogon ~]#
5、查询软件包配置文件
[root@bogon ~]# rpm -qc sudo /etc/pam.d/sudo /etc/pam.d/sudo-i /etc/sudo-ldap.conf /etc/sudoers [root@bogon ~]#
6、校验
[root@bogon tutor]# rpm -V sudo [root@bogon tutor]#
如果没有任何内容显示，说明sudo这个软件没有被改变过
7、软件包文件提取
比如不小心把/etc/inittab文件删除了，需要从软件包中重新提取恢复
1）先查找/etc/inittab这个文件属于哪个软件包
[root@bogon backup]# rpm -qf /etc/inittab initscripts-9.03.31-2.el6.centos.i686 [root@bogon backup]#
2）从软件包中解压/etc/inittab文件到当前目录
[root@bogon backup]# rpm2cpio /mnt/cdrom/Packages/initscripts-9.03.31-2.el6.centos.i686.rpm | cpio -idv ./etc/inittab ./etc/inittab 11182 块 [root@bogon backup]# ls etc [root@bogon backup]# ls etc inittab [root@bogon backup]#
3）然后从当前目录复制到/etc/inittab
[root@bogon backup]# cp etc/inittab /etc/inittab
四、源代码包安装
以安装proftpd为例子：
1）解压解包
[root@bogon softs]# ls proftpd-1.3.4b.tar.gz [root@bogon softs]# tar -xzvf proftpd-1.3.4b.tar.gz
2）进入解压后的目录
[root@bogon softs]# cd proftpd-1.3.4b [root@bogon proftpd-1.3.4b]#
3）先看看这个源码包中的文件
[root@bogon proftpd-1.3.4b]# ls acconfig.h include README README.PAM aclocal.m4 INSTALL README.AIX README.ports ChangeLog install-sh README.capabilities README.Solaris2.5x config.guess lib README.classes README.Unixware config.h.in locale README.controls RELEASE_NOTES config.sub ltmain.sh README.cygwin sample-configurations configure m4 README.DSO src configure.in Makefile.in README.facl stamp-h.in contrib Make.rules.in README.FreeBSD tests COPYING modules README.IPv6 utils CREDITS NEWS README.LDAP doc proftpd.spec README.modules [root@bogon proftpd-1.3.4b]#
可以看到里面有一个源码包典型的可以执行文件 configure
4）配置
[root@bogon proftpd-1.3.4b]# ./configure --prefix=/usr/local/proftpd checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu checking for gcc... no checking for cc... no checking for cl.exe... no configure: error: no acceptable C compiler found in $PATH See `config.log' for more details. [root@bogon proftpd-1.3.4b]#
./configure 在当前目录下执行
--prefix 指定安装目录
执行上述的配置命令后，出现错误，没有找到c编译器
使用yum安装gcc编译器，可以方便的解决gcc依赖的问题
[root@bogon proftpd-1.3.4b]#yum install gcc
安装好gcc编译器之后，重新执行配置
[root@bogon proftpd-1.3.4b]# ./configure --prefix=/usr/local/proftpd
5）编译
[root@bogon proftpd-1.3.4b]# make
把源代码编译成可执行文件
6）安装
[root@bogon proftpd-1.3.4b]# make install
五、脚本安装
以安装webmin为例子：
1）解压解包
[root@bogon softs]# tar -xzvf webmin-1.610.tar.gz
2）进入解压目录
[root@bogon softs]# cd webmin-1.610
3）可以查看一下README文件，路面有安装方式的说明
[root@bogon webmin-1.610]# more README
4）执行脚本安装
[root@bogon webmin-1.610]# ./setup.sh
安装过程会有一些交互，安装目录、日志文件存放目录、设置用户名密码之类的
[root@bogon webmin-1.610]# ./setup.sh *********************************************************************** * Welcome to the Webmin setup script, version 1.610 * *********************************************************************** Webmin is a web-based interface that allows Unix-like operating systems and common Unix services to be easily administered.
