RedHat系统yum配置

1        安装配置

1.1       获取安装包

进入http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/,找到如图中所示的三个包(视版本号而定)并下载。


1.2       卸载原系统yum

#           rpm –qa |grep yum | xargs rpm –e      

//rpm –qa命令列出所有已安装的rpm包,grep yum则从中查找出yum相关的包,xargs rpm –e则以查出的yum包为对象进行卸载。xargs将参数列表传递给其他命令(该处为rpm –e命令)。

1.3       安装yum

#           rpm –ivhyum-3.2.29-40.el6.centos.noarch.rpm –nodeps

#           rpm –ivhyum-metadata-parser-1.1.2-16.el6.x86_64.rpm nodeps

#           rpm –ivhyum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm –nodeps

//-ivh是列出详细安装进度,--nodeps是忽略依赖关系。

1.4       配置源repository

/etc/目录下新建CentOS-Base.repo文件,并参考附件1CentOS-Base.repo完成配置。

 

2        遇到的问题

问题1:有些库文件本来是安装了的,可能路径不对,所以安装时会报错。例如下面三个库在/lib64下是存在的,但由于默认的/usr/lib64下没有,所以报错了。

[root@localhost lib]# ldconfig

ldconfig: /usr/lib64/librpmbuild.so.1 is not asymbolic link

ldconfig: /usr/lib64/librpm.so.1 is not a symboliclink

ldconfig: /usr/lib64/librpmio.so.1 is not asymbolic link

[root@localhost lib]# ln -sf/lib64/librpmbuild.so.1 /root/usr/lib64/librpmbuild.so.1

ln: creating symbolic link`/root/usr/lib64/librpmbuild.so.1‘: No such file or directory

路径打错了,/root/usr/lib64应为/usr/lib64

[root@localhost usr]# ln -sf/lib64/librpmbuild.so.1 /usr/lib64/librpmbuild.so.1

[root@localhost usr]# ldconfig

ldconfig: /usr/lib64/librpm.so.1 is not a symboliclink

 

ldconfig: /usr/lib64/librpmio.so.1 is not asymbolic link

 

[root@localhost usr]# ln -sf /lib64/librpm.so.1/usr/lib64/librpm.so.1         

[root@localhost usr]# ln -sf /lib64/librpmio.so.1/usr/lib64/librpmio.so.1

[root@localhost usr]# ldconfig

 

问题2yum配置文件语法错误

Loaded plugins: fastestmirror, product-id,subscription-manager

Updating certificate-based repositories.

Repository ‘centosplus‘: Error parsing config:Error parsing "gpgcheck= ‘1 enabled=0‘": invalid boolean value

Determining fastest mirrors

http://centos.ustc.edu.cn/centos/%24releasever/addons/x86_64/repodata/repomd.xml:[Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"

Trying other mirror.

Error: Cannot retrieve repository metadata(repomd.xml) for repository: addons. Please verify its path and try again

 

问题3ImportError: No module named cElementTree

python少模块。把该模块给安装上就ok

[root@localhost yum.repos.d]# yum install rstatd

附件1.CentOS-Base.repo文件详解

# CentOS-Base.repo

# # This file uses a new mirrorlist systemdeveloped by Lance Davis for CentOS.

# The mirror system uses the connecting IP addressof the client and the

# update status of each mirror to pick mirrors thatare updated to and

# geographically close to the client. You shoulduse this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as afall back you can try the

# remarked out baseurl= line instead.

#

[base]                                                 --标识符

name=CentOS-6 – Base                                        --名称无所谓

--源地址,根据需要更新。原来是http://centos.ustc.edu.cn/centos/$releasesever/os/$basearch/,其实$releasesever$basearch是系统变量,根据实际源的目录改成常量也可以。

gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6   --GPG验证的url,与实际源相对应
