# Redhat Linux enterprise 5.4 Chinese display and Chinese Input Method

I was very excited when I installed Redhat Linux Enterprise 5.4, but I want to configure a search environment in Linux. Therefore, I must test Chinese search and support Chinese search.
When I first changed the Language to Chinese, it was a box that made me speechless.
Chinese display problems
Set Windows/fonts/simsun. ttc (the font file of /) is put on ftp, and then downloaded using ftp commands (even on the company's virtual machine, there is a way for meters, or else you can use a USB flash drive)
Cd to/usr/share, mkdir fontstruetype, cd fontstruetype, mkdir simsun
Put simsun. ttc under simsun and log on to the system again. Chinese support has been completed.
Installation of Chinese Input Method
So download little penguin input method, Official Website: http://www.fcitx.org/
I started to download fcitx-3.6.2.tar.bz2, but it seems that I have successfully decompressed the rice.

# Use Webmin to manage Redhat Enterprise Linux 6.0

1 Webmin installation Configuration

1.1 Webmin Introduction

Most people may feel a headache when configuring Various UNIX services, because there are too many services in UNIX, and each service does not seem easy to configure. People familiar with network service configuration in Windows are not familiar with writing configuration files manually in UNIX. In UNIX, you can install Webmin, a tool that allows you to configure various servers on UNIX servers through a browser. Webmin is an excellent management software for remote UNIX/Linix servers. Through the Control Panel (support for various languages, including simplified Chinese ), it allows users to easily configure various servers in UNIX, and even remotely configure all services running on UNIX. The default port is 10000, and SSL encryption is supported. It also allows users to directly modify user accounts, Apache, DNS, and file sharing settings on the server using browsers on remote computers. Webmin management is implemented through web pages. All operations are simple and intuitive, and they are very suitable for beginners. OS _list.txt IN THE webminobject directory lists UNIX systems currently supported by Webmin.

Compared with other GUI management tools, Webmin has the following significant advantages:

Web management enables Webmin to be able to manage both locally and remotely.

The plug-in structure makes Webmin highly scalable. Currently, the standard management module provided by Webmin covers almost common UNIX management modules, and third-party management modules are constantly developed.

Access Control and SSL support provide sufficient security for remote management.

International support and multi-language version.

In addition to UNIX systems, Webmin also provides modules for Webmin management. The management of Webmin mainly includes the following aspects.

Module management: This part includes inserting a module, deleting a module, copying a module, and resetting the category of the module. In addition, Webmin provides the ability to upgrade directly from the Internet.

Interface style management: Webmin provides multiple interface styles. In version 0.91, KDE and Caldera are provided. The Webmin interface style is actually a module. you can insert a new interface style. In addition, you can modify some Webmin interface parameters, such as the page background color and table background color.

International support: a major feature of Webmin is its multi-language support. Currently, Webmin supports languages such as English, French, German, Italian, Chinese, Japanese, and Korean.

Webmin server group: Webmin also provides the ability to discover and manage multiple Webmin servers, which greatly facilitates managing multiple UNIX servers at the same time.

Activity Log: The Webmin activity log is mainly used to audit the management activities of the system.

1.2 download and install Webmin

1. # Wget http://download.webmin.com/download/yum/webmin-1.510-1.noarch.rpm
2. # Rpm-ivh webmin-1.510-1.noarch.rpm
3. #/Etc/rc. d/init. d/webmin start

Automatically Start the Webmin service: To enable the Webmin service to automatically load as the system starts, run the "ntsysv" command to start the service configuration program and find the "webmin" service, add an asterisk (*) to the front of the asterisk (*) and select "OK.

Yum install gcc g ++

# Linux yum commands

Yum (all called Yellow dog Updater, Modified) is a Shell front-end Package Manager in Fedora, RedHat, and SUSE. Based on RPM package management, You can automatically download and install the RPM package from the specified server, automatically handle dependencies, and install all dependent software packages at a time, you do not need to download and install it repeatedly. Yum provides commands for searching, installing, and deleting one or more software packages. The commands are concise and easy to remember.

The command Format of yum is generally as follows: yum [options] [command] [package...]
[Options] are optional, including-h (HELP) and-y (when the installation prompt is "yes "), -q (the installation process is not displayed. [Command] is the operation object. [package...] is the operation object.

Some Common commands are summarized as follows:

The fastest image plugin for automatic search: yum install yum-fastestmirror
Install the yum graphic window plug-in: yum install yumex
View the list of possible batch installations: yum grouplist

1 Installation
Install yum install all
Yum install package1 install the specified installation package1
Yum groupinsall group1 installer group group1

2. update and upgrade
Yum update all updates
Yum update package1 update specified package1 package1
Yum check-update check updatable programs
Yum upgrade package1 upgrade specified package1 package1
Yum groupupdate group1 Upgrade Program Group group1

3 search and display
Yum info package1: package1
Yum list displays all installed and installable packages
Yum list package1 displays package1 installation of the specified package
Yum groupinfo group1 display group1 information of the Program Group yum search string find the installation package based on the keyword string

4. delete a program
Yum remove & #124; erase package1 Delete package1
Yum groupremove group1 Delete group1
Yum deplist package1 check package1 Dependencies

5. Clear Cache
Yum clean packages clear software packages in the cache directory
Yum clean headers clear headers in the cache directory
Yum clean oldheaders clear old headers in the cache directory
Yum clean, yum clean all (= yum clean packages; yum clean oldheaders) Clear the packages and old headers in the cache directory

For example, to install a game program group, first perform the following operations:
#: Yum grouplist
It can be found that the installable game package name is "Games and Entertainment", so that you can install it:
#: Yum groupinstall "Games and Entertainment"
All game packages are automatically installed. Here, the names of Games and Entertainment must be selected in double quotation marks, because the names of Games and Entertainment are ended when spaces are encountered in linux, therefore, you must tell the system to install the package named "Games and Entertainment" instead of "Games ".

You can also modify the configuration file/etc/yum. conf to select the installation source. It can be seen that the configuration program of yum is easy for many Parties. For more detailed options and commands, you only need to follow the command prompt line below: man yum

Yum groupinstall "KDE (K Desktop Environment )"

Yum install pirut k3b mikmod

Yum groupinstall "Server Configuration Tools"

Yum groupinstall "Sound and Video"

# Yum groupinstall "GNOME Desktop Environment"

# How to interact files between Linux and Windows on the host system in Vmware

Method 1: If your vmware is running on windows, you can use the vmtools sharing mechanism to exchange files, which is the fastest and most convenient.
(1) Install vmtools: After LINUX is started, click "VM-> Install VMware Tools". vmware virtualizes the required files into cdrom and decompress the tar.gz file in the cdrom, then run the vmware-tools-distrib/vmware-install.pl with the default settings until the installation is complete;
(2) In the virtual host settings of vmware for windows, add "share folder" to the LINUX virtual system, for example, c: \ downloads;
(3) in LINUX, under the/mnt/hgfs directory, you can see the shared directory and files in the directory in step 1, which are synchronized in real time with windows and can be read and written directly.
Method 2: Use winiso to make common files into an iso CD image, which can be accessed by linux after being mounted to vmware.

# In Linux, incorrect DNS settings have caused almost no access to ORACLE Data!

On a linux server, dns is recorded in vi etc/resolv. conf.

Because the network environment is changed, but the nameserver in the resolv. conf file is not modified, the database cannot be accessed!

After changing the resolv. conf file, it is as fast as it is!

# Linux Privilege Escalation

Log On with root
Use the usermod command
Usermod-g group G adm, root your Username

# Mount the ISO file in Linux
