linux中没有默认安装的gcc,折腾了一番,终于搞好,记录备忘。
[root@localhost local]# gcc
bash: gcc: command not found...
查看系统版本:
[root@localhost ~]# cat /proc/version
Linux version 3.10.0-229.el7.x86_64 (mockbuild@x86-035.build.eng.bos.redhat.com) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-7) (GCC) ) #1 SMP Thu Jan 29 18:37:38 EST 2015
[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.1 (Maipo)
red hat中yum需要付费
[root@localhost local]# yum install gcc
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
主要有两种方式解决此问题:
一、通过yum安装,第一种通过替换成CentOS的yum,然后直接 yum install gcc 安装;
第二种通过本地镜像文件来装,用iso做一个yum库(无法联网时的办法)。
二、直接安装gcc,第一种通过rpm安装(依赖包挺多的,很繁琐);第二种通过gcc压缩包安装。
此处只叙述了本人成功的一种方式,其他方式可以搜一下,有很多文章进行了叙述。
1、安装yum,替换成CentOS中的yum,通过yum install gcc安装,通过此方式要确定服务器能上网
a. 备份原 yum
【linux|Red Hat Enterprise Linux Server release 7.1 (Maipo) 安装gcc 的几种方式】
mv /etc/yum.repos.d/redhat.repo /etc/yum.repos.d/redhat.repo.backup
b. 删除red hat yum源
rpm -qa | grep yum | xargs rpm -e --nodeps
c. 下载新的yum包,因为是red hat 7 安装CentOS 7 版本的yum源,版本一定要对应,可避免不少麻烦
去http://mirrors.163.com/centos/7/os/x86_64/Packages/下载如下文件
下载:yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-3.4.3-154.el7.centos.noarch.rpm
yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
python-iniparse-0.4-9.el7.noarch.rpm
或者命令下载直接:
wgethttp://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wgethttp://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wgethttp://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-154.el7.centos.noarch.rpm
wgethttp://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
d. 安装新的yum包
rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh yum-3.4.3-154.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
安装后可通过命令查看:
[root@localhost ~]# rpm -qa |grep yum
yum-plugin-fastestmirror-1.1.31-42.el7.noarch
yum-3.4.3-154.el7.centos.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
如果报错缺少包,可以将包名复制到http://mirrors.163.com/centos/7/os/x86_64/Packages/ 下去找对应的包,并下载安装。
如:可能会缺少python-urlgrabber这个包,就先下载安装这个包。
e. 将CentOS的yum源更新到red hat中
下载地址:http://mirrors.163.com/.help/CentOS6-Base-163.repo
将repo文件移动到 /etc/yum.repos.d/下,并编辑 (把版本号换成7就行)
[root@localhost ~]# mv CentOS6-Base-163.repo /etc/yum.repos.d/
[root@localhost ~]# vi CentOS6-Base-163.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

baseurl=http://ftp.sjtu.edu.cn/centos/7/contrib/$basearch/
gpgcheck=0

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
如果后面有报找不到key的问题,可以下载对应的key,然后将gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
指定成本地文件gpgkey=file:///usr/local/yum/RPM-GPG-KEY-CentOS-6
f. 清理yum缓存
[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache
g. 就可以安装测试啦!
yum install gcc
