第四章部署yum仓库服务
1.笔记
systemctl start 命令 ：重启
systemctl enable 命令 ：开机自启动
netstat -anput | grep 命令：查看是否开启
echo $ ?:判断上条命令是否执行成功，是0执行成功，非0不成功
yum provides 包：查看包名
2.基于ftp://的本地光盘创建yum仓库过程
yum -y install ftp （安装ftp 软件包）
umount /dev/sr0 （卸载光盘 /dev/sr0）
mkdir /var/ftp/centos7 （建立目录，在/var/ftp/centos7）
mount /dev/sr0 /var/ftp/centos7/（挂载/dev/sr0 挂载/var/ftp/centos7）
vim /etc/yum.repos.d/local.repo （编辑/etc/yum.repos.d/local.repo）
[local]（仓库名称）
name=local（仓库名称）
baseurl=ftp://192.168.203.4(本机地址)/centos7（指定rpm包的位置）
gpgcheck=0（禁用gpg 校验）
enabled=1（启用本地yum仓库）
yum -y clean all（清空缓存）
yum makecache（重建缓存）
3.centos7配置在线yum仓库yum源和EPEL源
http://rpm.pbone.net/
http://rpmfind.net/
rpm-Uvhhttps://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
- 挂载完镜像后进入与/etc/yum.repos.d下创建一个文件夹把文件备份后
cd /etc/yum.r*
mkdir a/
mv C* a/
2.下载新的CentOS-Base.repo 到/etc/yum.repos.d/或下载后将文件传输到虚拟机的/etc/yum.repos.dxia下
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行yum -y clean all 清除缓存，运行 yum makecache 生成新的缓存
[root@bogon yum.repos.d]# yum -y clean all
[root@bogon yum.repos.d]# yum makecache
安装EPEL源
[root@bogon yum.repos.d]# yum list | grep epel-release
epel-release.noarch 7-9 extras
[root@bogon yum.repos.d]# yum install -y epel-release
