Basic commands for Linux learning from deploying test environments, the main Linux commands used to deploy the test environment are:
1. Copy files from afar to local directory:
SCP [parameters] [Original path] [Target path]
SCP remote User name @IP address: filename Local user name @IP address: filename 1
-V is the same as the-V meaning in most Linux commands, and is used to show progress. Can be used to view connections, authentication, or configuration errors.
-C enables compression options.
-P Select the port. Note-P has been used by RCP.
-4 forcibly use IPV4 address.
-6 forcibly use IPV6 address.
Example:
SCP root@***.***.***.***:/opt/soft/nginx-0.5.38.tar.gz/opt/soft/This input does not require a username and password
2. Create a table of contents
Mkdir/mnt/vcdrom
3. Mounting a mirrored file
Mount [-t vfstype] [-O options] Device dir
A.-t vfstype Specifies the type of file system, which is not usually specified. Mount will automatically select the correct type
DOS FAT16 file system: MSDOS
Windows 9x FAT32 file system: VFAT
Windows NT NTFS file system: NTFS
Mount Windows file network share: SMBFS
UNIX (LINUX) file network share: NFS B.-o options are primarily used to describe how devices or files are hooked up
Loop: Used to mount a file as a hard disk partition to connect the system
RO: Use read-only way to hook up equipment
RW: Hook up device with read-write mode
Iocharset: Specifies the character set used to access the file system
C.device the device to hook up (Mount).
D.dir (mount point) of the device on the system.
For example:
Mount-t Iso9660-o loop/root/rhel-5.10-x86_64-dvd.iso/mnt/vcdrom/
4. See if the mount was successful
Df–lh
5. Install Dependency Pack
Yum Install * * *
6. See if the dependent package installation was successful
RPM-Q * * *
7. Edit the contents of the file
Vi/etc/yum.repos.d/cluster.repo
8. Set up a user group * *
Groupadd * * 9. Add User
Useradd option User Name
-C Comment Specifies a section of an annotation description.
The-D directory specifies the home directory, and if this directory does not exist, the-m option can be used to create the main catalog.
The-G user group specifies the user group to which the user belongs.
-G user group, where the user group specifies the additional group to which the user belongs.
-S Shell file specifies the user's login shell.
The-u user number specifies the user's user number, and if the-o option is available, the other user's identification number can be reused.
User name Specifies the login name of the new account.
Example:
Useradd-g oinstall-g dba-d/home/oracle Oracle
10. Set User Password
passwd Oracle
Enter Password: * * *
11. Set Permissions
chown [Options] ... Owner [: [Group]] file ...
-C Displays information about the changed part
-F ignores error messages
-H Repair Symbolic link
-R handles all files in the specified directory and its subdirectories
-V Display detailed processing information
-deference to the point of the symbolic link, not to the linked file itself
Example:
Chown-r oracle:oinstall/home/oracle– changes the/home/oracle directory and the owner of its subdirectories to Oracle, and the group to which it belongs is Oinstall.
12. Reboot after modifying configuration file:
Source file name
source. bash_profile
13. Delete Files
RM file Name
14. View current Working directory
Pwd
15. Go back to the parent directory of the current directory
Cd..
16. Return to the root directory of the current directory
CD/
