[root@localhost ~]#

挂载系统ISO镜像，配置yum源

由于内网无法访问网络，所以需先挂载centos7的ISO镜像，然后配置yum源安装mysql5.6编译所需要的依赖包
创建ISO镜像存放目录并上传ISO镜像文件
1. 上传镜像到/opt
2. mount -o loop /opt/CentOS-7-x86_64-DVD-1804.iso /mnt 挂载镜像到/mnt
3. df -h #查看磁盘

#显示这一行说明已经镜像已经挂载成功
配置yum源：
4. mkdir /etc/yum.repos.d/yumbak 备份yum源
mv *.repo yumbak/ #备份原有配置文件
5. vim /etc/yum.repos.d/local.repo #新建yum源，了解到系统会先使用CentOS-Base.repo
[local]
name=local
baseurl=file:///mnt
gpgcheck=0
enabled=1
[local]
name=local
baseurl=file:///mnt #此处写镜像挂载目录
gpgcheck=0
enabled=1
6.yum clean all 清空yum缓存
Loaded plugins: fastestmirror
Cleaning repos: centos7-iso
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors
7.yum makecache
尝试yum安装gcc是否可以安装
8. yum -y install gcc
[root@cbp3 ~]# ll /mnt/
