CentOS 安装 sl（小火车）

1. 安装

• 一般命令行中执行 yum -y install sl

2. 上面如果不行

• yum -y upgrade
• 备份/etc/yum.repos.d/CentOS-Base.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

• 下载对应版本repo文件，放入/etc/yum.repos.d/（操作前请做好相应备份）

#Centos7:

wget -P /etc/yum.repos.d http://mirrors.163.com/.help/CentOS7-Base-163.repo

#Centos6:

wget -P /etc/yum.repos.d http://mirrors.163.com/.help/CentOS6-Base-163.repo

#Centos5:

wget -P /etc/yum.repos.d http://mirrors.163.com/.help/CentOS5-Base-163.repo

3. 运行以下命令生成缓存

• 执行

yum clean all
yum makecache

4. 再次执行（还是不行）

[root@localhost packages]# yum -y install sl
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
No package sl available.
