RedHat系Linux软件包管理
RedHat系Linux软件包管理
一、RPM包的管理 www.2cto.com
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 ~]#
[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]#
www.2cto.com
[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]#
www.2cto.com
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]#
[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]#
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]#
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 ~]#
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 www.2cto.com
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]#
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]#
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

/etc/sudoers
[root@bogon ~]#
6、校验
[root@bogon tutor]# rpm -V sudo
[root@bogon tutor]#
[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]#
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]#
./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
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]#
[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]#
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]#
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

Webmin uses its own password protected web server to provide access
to the administration programs. The setup script needs to know :
- What port to run the web server on. There must not be another
web server already using this port.
- The login name required to access the web server.
- The password required to access the web server.
- If the webserver should use SSL (if your system supports it).
- Whether to start webmin at boot time.

安装完成我们就看见在远程用浏览器登录来管理服务器了
webmin是一个非常强大基于Web的Unix/Linux系统管理工具
