Linux Learning one: Installing JDK and Tomcat

Using SECURECRT

First, the installation of CentOS Rzsz,

1.yum Automatic Installation: (yum installation Rzsz)

Yum Install Lrzsz

　　　　

2. The manual installation method is as follows: (the package is a problem, or the first way)

2.1. Download software rzsz-3.48.tar.gz

wget http://freeware.sgi.com/source/rzsz/rzsz-3.48.tar.gz Download.

2.2 Unzip the tar zxvf rzsz-3.48.tar.gz

2.3. Install CD rzsz-3.48

Make POSIX or make Linux

2.4. If the following prompt appears:

-bash:make:command not found.

2.5. The table system does not have the compiler installed, SSH installation:

Yum-y install gcc automake autoconf libtool make

2.6. Execute the make POSIX command again

[[email protected] src] #make POSIX

ln sz Zcommandi

[[Email protected] src]#

3. In order to facilitate the use of this tool, copy the relevant files to the directory/usr/bin below, only need to copy 2 files RZ and SZ

CP RZ Sz/usr/bin

"Note:" I was following the automatic installation, the first method.

Second, use the RZ command to upload files

The file transfer protocols under SECURECR are ASCII, Xmodem, Ymodem, Zmodem



ASCII: This is the fastest transport protocol, but only text files can be transferred.



Xmodem: This ancient transmission protocol is slow, but due to the use of CRC error detection method, the transmission accuracy rate can be as high as 99.6%.



Ymodem: This is an improved version of Xmodem, which uses 1024-bit segments to deliver faster than Xmodem.



Zmodem:zmodem adopts the stream-flow (streaming) transmission mode, the transmission speed is fast, but also has the function of automatically changing the section size and the breakpoint continuation transmission, the fast error detection and so on. This is currently the most popular file Transfer protocol



Set default upload Download directory

Options->session Options->terminal->xmodem/zmodem

Set upload and download directories on the right



Using Zmodem to upload files from a client to a Linux server

1. Log in to the Linux terminal with SECURECRT.

2. Select the path where you want to place the uploaded file, in the directory and then enter the RZ command, SECURECRT will pop up the file selection dialog box, find the file you want to upload in the search scope, press the Add button. Then OK can upload the file to Linux.

Or, in the Transfer->zmodem upoad list pop-up File selection dialog box, select the file and press the Add button. Then the OK window closes automatically. Then under Linux, select the directory where the files are stored and enter the RZ command. Liunx the file to the directory.

To download files to the client using Zmodem:

SZ filename

Zmodem receive can start on its own. The downloaded file is stored in the default download directory you set.



If the RZ, sz command is not valid, please install RZSZ-0.12.20-853.2.I586.RPM first

The specific installation method is:

RPM-IVH rzsz-0.12.20-853.2.i586.rpm

Common commands:
First, LS only lists the file name (equivalent to Dir,dir can also be used)
-A: Lists all files, including hidden files.
-L: List form, which contains most of the properties of the file.
-R: Recursive display.
--help: Help for this command.
Second, CD change directory
CD/: Go to the root directory
CD: Go back to your directory (different directories are different, root is/root,xxt for/home/xxt
Cd.. : Back to Parent directory
PWD: Displays the directory where you are currently
Three. Less file name: View the contents of the file.
Four. Q exit the Open file.
Five. Upload file: RZ Select the file to be transferred, OK.
Six. download file: Sz Specify the file name, enter to hit, that is downloaded to the Securecrt/download directory.
Seven: Delete file: RM Delete file, rmdir delete empty directory.

Eight. Show the last 20 commands entered: History 20

Nine. Get help command--help View command under detailed parameters: such as: RZ--help, Sz--help.


10. The CD Entry command to a folder:
mkdir+ folder name command to create a folder
sz+ file name from server-side send files to native command
RZ commands to transfer files from the local to the server side
ll lists all files in the current directory, including details for each file
Dir to the current folder
VI Open the current file
11. When editing a file:
A switch to edit mode
CTRL + C Exit Edit mode
DD Delete entire row
: Q Exits the current file
: W writes and saves the current file
-F Force XX parameters ...

Other commands:
1.PS-EF//View the server process as a list of the server processes that are displayed.
PS shows the process currently running on the system/usr/bin/ps [options]-e display each now running process-F to generate a full list

4. I am generally accustomed to using the PS–EF command to see the server process as a list, and to see the process of the server with the command Pstree so that the server process is displayed as a tree.
The advantage of the Pstree command is that the parent process of a process can be identified immediately. You may need to use the-P option to display the PID for each process, and the-u option to display the user name that started the process.
In general, this tree structure is longer, and you need to do so Pstree–up | Less this will give you an overview of the entire process tree structure.

Third, install the TAR package

1. Copy the installation files to your directory, and if you are logged in as root, copy the software to/root.
#cp Xxx.tar.gz/root
2, decompression.
#tar Xvzf xxx.tar.gz
or simply double-click Unzip.
3, check the compilation.
#./configure
4. After checking, the makefile file will be generated for compiling. At this point, you can start compiling.
#make.
5, after the successful compilation, start the installation.
#make Install
6. After installation, the files generated during the process of compiling the temporary files and configuration should be cleared.
#make Clean
#make Distclean
This completes the installation.
If you want to uninstall, execute make Uninstall

Appendix: Configuring Environment Variables for JDK:

Three ways to configure environment variables

　　

After the JDK is installed, go to the JDK Bin directory and execute "./java" to see if the environment variable is configured, you can enter "Java/javac" in any directory.

In the same vein, starting Tomcat is also going into the bin directory of Tomcat, executing "./startup.sh", which starts Tomcat

1. Modify the/etc/profile file

This approach is recommended if your computer is used only as a development, because all user shells have the right to use these environment variables, which can pose a security issue for the system.

• Open/etc/profile with a text editor

Vi/etc/profile

(click "I" to edit, press ESC, then ":" Colon, press "q!" : Do not save, press "Wq": Save. Press the ENTER key to confirm)
• At the end of the profile file, add:

Java_home=/usr/java/jdk1.7.0_75
Path= $JAVA _home/bin: $PATH
Classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar
Export Java_home
Export PATH
Export CLASSPATH

Save: Source/etc/profile

Then, enter the command: Java, Javac will be able to

• No need to log in again
• annotations
A. You want to change/USR/SHARE/JDK1.5.0_05JDK to your JDK installation directory
B. Use the colon ":" to separate the paths under Linux
C. $PATH/$CLASSPATH/$JAVA _home is the value used to refer to the original environment variable
When setting environment variables, be careful not to overwrite the original value, which is a
A common error.
D. Current directory in Classpath "." It is a common mistake to throw away the current directory.
E. Export is exporting these three variables as global variables.
F. The case must be strictly differentiated.

2. Modify the. bashrc file
　　　　
This method is more secure, it can control the use of these environment variable permissions to the user level, if you need to give a user permissions to use these environment variables, you only need to modify their personal user home directory of the. bashrc file on it.

• Open the. bashrc file in the user directory with a text editor
• At the end of the. bashrc file, add:
　　　　　　
Set java_home=/usr/share/jdk1.5.0_05
Export Java_home
Set path= $JAVA _home/bin: $PATH
Export PATH
Set classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar
Export CLASSPATH

• Re-login

3. Set variables directly under the shell

Do not support the use of this method, because the shell, your settings are invalid, so this method is only temporary use, and later to use the time to reset, more trouble.

Simply execute the following command at the shell Terminal:

Export java_home=/usr/share/jdk1.5.0_05
Export path= $JAVA _home/bin: $PATH
Export classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

Iv. Linux System Open the system firewall port:

Linux System Open firewall port

Test environment Redhat 5.4, open 3306 and 8080 ports

Modify the Iptables file under/etc/sysconfig:
