1.用yum安装软件报错

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was 14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org' # 这种错误是因为网络问题,没有配置/etc/resolv.conf,在这个文件里写入nameserver 8.8.8.8即可.

2.在CentOS6上配置Base源

# 备份你的原镜像文件,出错后还可以恢复 mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup # 下载新的CentOS-Base.repo到/etc/yum.repos.d/ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo   yum makecache  # 生成缓存 yum clean all  # 清除缓存 chkconfig NetworkManager off service NetworkManager stop

3.在CentOS6上配置EPEL源

1 2 3 4 5 6 7

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo yum repolist  # 验证是否成功 # 如果出错,就编辑vi epel.repo,取消baseurl的注释,将mirrorlist行注释,就差不多了.   # Centos7同理 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

4.CentOS6关停iptables

iptables -F /etc/init.d/iptables save chkconfig iptables off service iptables stop

5.hping3解决编译报错问题

在安装完gcc后,编译报错,需要编辑bytesex.h文件,添加一行 vim bytesex.h #if      defined(__i386__) \         || defined(__x86_64__) \         || defined(__alpha__) \   # hping3命令用法详解:http://www.searu.org/16384.html # hping3命令:http://man.linuxde.net/hping3 # hping的使用方式:http://blog.youkuaiyun.com/lhl_blog/article/details/19572631 # iftop的安装和简单使用:https://www.cnblogs.com/chaichuan/p/4442610.htm
