1. Operating system basic information: UNAME-A will display the operating system name, hostname, operating system version information, operating system version information, hardware type, CPU type, platform information.
2. Kernel Information: Modify the/etc/system file to change
Absrtact: It is quite simple to install a virtual root-environment Apache tree on Linux. This example uses the red Hat 6.* and the Apache 1.3.12. It also contains the PHP4 (as an Apache module) and the installation of PERL5 on the directory tree where the virtual root is being virtualized. In addition, MOD-SSL and Mod-perl are installed.
Introduced
I have used the CERN httpd to install and use a Web server in a virtual root environment. Creating a virtual root environment for a Web server has
promptSun's operating system has a boot-prom state prior to entering the Solaris operating system or system startup. The way to enter this state is to press the Stop+a on the keyboard at the same time, if there is no stop this function key (PC keyboard), you can use the Ctrl+break key to enter. If you are in a boot-prom state, at the OK prompt and your Solaris operating system is still running, you can use
The Solaris underlying network configuration commands are recorded as follows:
1. Configure SSH to allow root login
Vi/etc/sshd/sshd_config
Permitrootlogin Yes
Reboot SSH Service
Svcadm Restart SSH
2. Network configuration
1 Configure IP address and host name
# vi/etc/hosts
#
:: 1 localhost 127.0.0.1 localhost 192.168.50.200 vmtest loghost
2) Configure the host name
# Cat/etc/nodename
Vmtest
3) Configure the subnet mask
# Cat/etc/netmas
1. System Environment Preparation
A. Change the system shell to bash because the system default shell is not easy to use.
# which bash
Usr/bin/bash
# usermod-s/usr/bin/bash Root
B. Create a System. Profile file:
# Cp/etc/skel/local.profile/.profile
C. Add the following in the. profile file
Path=/usr/bin:/usr/local/bin:/usr/ucb:/etc:/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/ccs/bin:/opt/csw/bin:.
Export PATH
Export ps1= '/u:/w# '

Solaris is a computer operating system developed by Sun Microsystems. It is considered to be one of the derivative versions of UNIX operating systems. Solaris starts to support ipv6 after version 8.0. Some Ipv6 features are as follows: IPv6 adds an added address space and Improves Internet functions by using simplified header formats, authentication and confidentiality support, and automatic Address Allocat
I. DNS basics [DNS System (server) Working Principle and attack protection methodology]
DNS: Domain Name System, the Domain Name resolution server. Its role on the Internet is to convert the Domain Name into an IP address that can be recognized by the network.BIND: Berkeley Internet Name Domain, which is the most widely used DNS protocol in unix.For example, blog.sina.com.cn, blog is a level-4 domain name, sina is a level-3 domain name, com is a level-2 domain name, cn is a top-level domain name
When you telnet to a Solaris 10 server when Solaris 10 fails to telnet, the system prompts telnet: Unable to connect to remote host: Connection refused serial port logon to view # svcs-a | grep telnetuninitialized Nov_12 svc: /network/telnet: the default status shows uninitialized, not disabled or offline, or maintenance. # Svcadm enable svc:/network/telnet: default # svcs-a | grep telnetuninitialized Nov_1

If ["$ DIRECTORY" = ""]
Then
