Rhel Configuring local Yum sources with system image files

1. Upload the system image file Rhel-server-7.0-x86_64-dvd.iso to the/USR/LOCAL/SRC directory using the WinSCP.exe tool

2. Remotely connect to the RHEL server using the Putty.exe tool

3. Mount the system image file

• Mkdir/media/cdrom #新建镜像文件挂载目录
• CD/USR/LOCAL/SRC #进入系统镜像文件存放目录
• LS #列出目录文件, you can see the system image file just uploaded

1. Mount-t Iso9660-o Loop/usr/local/src/rhel-server-7.0-x86_64-dvd.iso/media/cdrom #挂载系统镜像
2. Cd/media/cdrom #进入挂载目录, use the LS command to see that a file already exists.

Remark: Umount/media/cdrom #卸载系统镜像

4. Set up automatic mount system image file on boot

1. Vi/etc/fstab #添加以下代码. Enable automatic mount on boot
2. /usr/local/src/rhel-server-7.0-x86_64-dvd.iso/media/cdrom iso9660 defaults,ro,loop 0 0
3. : wq! #保存退出

Note: iso9660 use df-t to view devices

5. Configure local Yum Source

2. Cd/etc/yum.repos.d/#进入yum配置目录
4. Touch Rhel-media.repo #建立yum配置文件
6. VI Rhel-media.repo #编辑配置文件, add the following:
8. [Rhel-media]
10. Name=Red Hat Enterprise Linux 7.0 #自定义名称
12. Baseurl=file:///media/cdrom #本地光盘挂载路径
14. enabled=1 #启用yum源, 0 is not enabled, 1 is enabled
16. gpgcheck=1 #检查GPG-key,0 for no check, 1 for inspection
18. gpgkey=file:///media/cdrom/RPM-GPG-KEY-redhat-release #GPG-key Path
20. : wq! #保存退出

6. Install the software automatically using the Yum command

1. Yum Clean all #清除yum缓存

Yum Makecache #缓存本地yum源中的软件包信息

1. Yum Install httpd #安装apache
2. RPM-QL httpd #查询所有安装httpd的目录和文件

1. Systemctl Start Httpd.service #启动apache
2. Systemctl Stop Httpd.service #停止apache
3. Systemctl Restart Httpd.service #重启apache
4. Systemctl Enable Httpd.service #设置开机启动

RHEL 7.0 defaults to using firewall as the firewall, where the iptables firewall is changed.

Close firewall:

2. Systemctl Stop Firewalld.service #停止firewall
4. Systemctl Disable Firewalld.service #禁止firewall开机启动
6. Yum Install iptables-services #安装iptables
8. Vi/etc/sysconfig/iptables #编辑防火墙配置文件
10. # Firewall configuration written by System-config-firewall
12. # Manual Customization of this file are not recommended.
14. *filter
