Summarize the points of knowledge

1. If []

Then

elif []

Else

Fi

Standard syntax for IF statements

There must be a space between the "if" and the judgment statement.

You must end with "fi", or you will get an error.

2. ISO image Mount statement

Mount-t Iso9660-o Loop/mnt/rhel6.4.iso/mnt/yumiso

The CD-ROM mount statement is

Mount-t Iso9660/dev/cdrom/mnt/testiso

You can see that the mount image requires more than one loop parameter.

Similarly, file system mounts involve a configuration file of/etc/fstab

The configuration behavior of the ISO image according to its syntax format

/mnt/rhel6.4.iso/mnt/yumiso iso9660 Loop 0 0

3. Yum Source Configuration

The Yum source automatically loads all configuration files that end with. Repo in the/ETC/YUM.REPOS.D directory.

Repo the format in the configuration file.

No other characters, such as spaces, can appear at the beginning of the configuration file, or a parsing error will occur. At first, in order to be beautiful in the script, each line added a space, resulting in an error.
