Ubuntu server deployment issues

When you are new to Ubuntu server 12.04, you can choose to install it on a VM. The system is automatically installed. After the installation, I encountered a series of problems when starting the system. With the help of some netizens, I solved them one by one and kept updating them.

1. desktop environment Installation

Just entered the system and found that it was in the form of a command line. This is depressing. The command line is really difficult for people who are used to the window interface. With the help of a netizen, I found the command for installing the graphic interface. Ubuntu Series desktop actually has several desktop applications, including Ubuntu-desktop, kmeanut-desktop, and xubuntu-desktop. This document uses Ubuntu-desktop as an example to describe how to use this method.

Sudo apt-Get update // refresh the download list

Sudo apt-Get install Ubuntu-desktop // install graphical desktop

Or sudo aptitude install Ubuntu-Desktop

 

2. Install MySQL

Sudo apt-Get install mysql-server // install MySQL

Mysql_secure_installation // configure MySQL Security Settings

Sudo mysqladmin-H localhost-u root-p version // view the MySQL running status and version

It is very convenient to configure the MySQL database in versions earlier than ubuntu12.04. You only need to run three commands:

Sudo apt-Get install mysql-Admin

Sudo apt-Get install mysql-query-Browser

The MySQL database has been fully upgraded in Ubuntu 12.04. Therefore, you only need to execute two commands.

Sudo apt-Get install mysql-workbench

　　

　　Unable to remotely MySQL:

Enable remote authorization: Use the root user to log on to MySQL (MySQL-u root-p) locally, and then run grant all privileges on database. database object to username @ 'client ip' identified by 'Password'; (for example, grant all privileges on *. * To root @ '%' identified by '000000 ′;)

View port and IP: netstat-an | grep 3306

TCP 0 0 127.0.0.1: 3306 0.0.0.0: * listen

127.0.0.1 indicates that an IP address is bound and only local access is allowed (available in the following method); Listen indicates that the port is enabled.

Unbind an IP Address: in the/etc/MySQL/My. CNF file, bind-address is bound to 127.0.0.1, change it to the Ubuntu IP address, and save the modification.

Restart the database: Run/etc/init. d/MySQL restart to restart the MySQL service.

 

 

3. Install apache2

　　apt-get install apache2// Install apache2. the default document root directory in Ubuntu is/var/WWW, And the configuration file/etc/apache2/apache2.conf is used,

4. Install PhP5

Apt-Get install PhP5 // install PhP5

　　apt-get install Libapache2-mod-php5 // install PhP5 and Apache PhP5 modules


　　/etc/init.d/apache2 restart// Restart Apache

5. Obtain MySQL support for PhP5

　　apt-cache search php5// Check the PhP5 module first.

// Install the required modules, for example, the following command:

　　apt-get install php5-mysql php5-curl php5-gd php5-intl php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

 

 

After installing lamp, we found that the original lamp environment can be installed with one click. After Linux Ubuntu is installed, use
Sudo apt-Get install tasksel
Sudo tasksel install lamp-Server

 

6. Configure the IP address

By default, IP addresses are allocated through DHCP. The following are static IP addresses.

VI/etc/Network/interfaces // set the IP address for opening the file, as shown below:

Auto eth0
Iface eth0 Inet DHCP // DHCP indicates automatic allocation,

Change

Auto eth0

# Iface eth0 Inet DHCP

　　　　　　　　iface eth0 inet static
　　　　　　　　address 192.168.80.129
　　　　　　　　netmask 255.255.255.0
　　　　　　　　gateway 192.168.80.2

Remember to restart the service after configuration takes effect:/etc/init. d/networking restart

7. Configure the DNS server

Vim/etc/resolv. conf // temporary configuration, expired after restart

Vim/etc/resolvconf/resolv. conf. d/base // permanent settings

Change the content of the above file:

Nameserver 192.168.80.2 // master
Nameserver 8.8.8.8 // standby

Remember to restart the service after configuration takes effect:/etc/init. d/networking restart

8. New users

Useradd is an elf executable program that adds a user name and creates a group name that is the same as the user name. However, it does not create a user name-based directory in the/home directory, you are not prompted to create a new password.

-B,-base-Dir base_dir specifies the base Directory of the Home Directory

-D,-home-Dir home_dir specifies the Home Directory

-G,-gid Group specifies GID

-L,-no-log-init do not add the user to the lastlog and faillog Databases

-M,-no-create-home do not create the Home Directory

-P,-Password specifies the password of the new user

-R,-system: Create a system account

-S,-shell specifies Shell

For example:Useradd-m-D/home/newuser-S/bin/bash-G Sudo-P newuser

Passwd newuser-- Change the password (ID newuser -- view group)
