[Alibaba server] Ubuntu 16.04 LAMP environment construction

After installing Ubuntu16.04, it is a blank Ubuntu. My purpose is to build a LAMP environment, and by the way a Python Django environment.

basic settings

1. Configure the network environment

The administrator has assigned a static IP, so it is necessary to further configure the network environment

Configure DNS: upper right corner network connection->edit link->wired connection 1->IPv4 settings->DNS server: 202.112.80.106->save

Login gateway: For campus network users, only by logging in to the gateway can access the external network

Test: ping www.baidu.com

2. Set the root password

sudo passwd

Switch to root user: su or su - or su root

Switch to normal user: su username or logout

3. Update source

sudo apt-get update

The source saved file is: /etc/apt/sources.list

Install common software

1.SSH

sudo apt-get install openssh-server

Check the status: service ssh status/start/stop/restart

或：/etc/init.d/ssh status/start/stop/retsrt

In fact, the service command is to execute the /etc/init.d script, and the functions of the two are the same

2.Vim

sudo apt-get install vim

3.Tree
“
sudo apt-get install tree

4.Git

sudo apt-get install git

Build LAMP

1. Install Apache

sudo apt-get install apache2

Test: The browser accesses the IP of http://Ubuntu , and the It Works! webpage appears.

Check the status: service apache2 status/start/stop/restart

Web directory: /var/www

Installation directory: /etc/apache2/

Global configuration: /etc/apache2/apache2.conf

Listening port: /etc/apache2/ports.conf

Virtual host: /etc/apache2/sites-enabled/000-default.conf

2. Install MySQL

sudo apt-get install mysql-server mysql-client

Test: mysql -u root -p

View status: service mysql status/start/stop/retart

Check the listening port: netstat -tunpl or netstat -tap

3. Install PHP

sudo apt-get install php7.0

Test: php7.0 -v

4. Install other modules

sudo apt-get install libapache2-mod-php7.0

sudo apt-get install php7.0-mysql

restart the service

service apache2 restart

service mysql restart

Test whether Apache can parse PHP

vim /var/www/html/phpinfo.php

The file writes:

Browser access: http://ubuntu address/phpinfo.php, the PHP Version page appears

5. Modify permissions

sudo chmod 777 /var/www

6. Install phpMyAdmin

sudo apt-get install phpmyadmin

Installation: Select apache2 and click OK. The next option is to configure the database and enter a password.

Create phpMyAdmin shortcut: sudo ln -s /usr/share/phpmyadmin /var/www/html

Enable Apachemod_rewrite module: sudo a2enmod rewrite

Restart the service:

service php7.0-fpm restart

service apache2 restart

Test: Browser access: http://ubuntu address/phpmyadmin

7. Configure Apache

vim /etc/apache2/apache2.conf

Add to:

AddType application/x-httpd-php .php .htm .html

AddDefaultCharset UTF-8

Restart the Apache service

install python package

1.pip

sudo apt-get install python-pip

2.Django

pip install django

Test: import django

3.MySQL-python

pip install MySQL-python

Test: import MySQLdb

common problem

1. Secure SSH Client connection error

错误：algorithm negotiation failed

solve:

Modify the sshd configuration file: vim /etc/ssh/sshd_config

In the configuration file add:

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

MACs hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,hmac-sha1-96,hmac-md5-96

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,[email protected]

Restart the sshd service: service ssh restart

2. Xshell or Xftp Chinese garbled characters

Xshell: File->Properties->Terminal->Encoding->UTF-8>

Xftp: File -> Properties -> Options -> Check Use UTF-8 encoding

3. Error installing MySQL

mistake:

The following packages have unmet dependencies:

mysql-client : Depends: mysql-client-5.5 but it will not be installed

mysql-server : depends on: mysql-server-5.5 but it will not be installed

E: The bug cannot be fixed because you require some packages to remain as they are, that is, they break dependencies between packages.

Solution: Two workarounds

Use the download source that comes with Ubuntu, do not use other sources (such as NetEase)

Manual installation

Download MySQL: http://dev.mysql.com/downloads/mysql/

Upload to Ubuntu using FTP tool

Release: tar -xvf mysql-server_5.7.13-1ubuntu16.04_i386.deb-bundle.tar

Install:

sudo dpkg -i libmysqlclient20_5.7.15-1ubuntu16.04_amd64.deb libmysqlclient-dev_5.7.15-1ubuntu16.04_amd64.deb libmysqld-dev_5.7.15-1ubuntu16.04_amd64.deb mysql-common_5.7.15-1ubuntu16.04_amd64.deb mysql-community-source_5.7.15-1ubuntu16.04_amd64.deb mysql-community-client_5.7.15-1ubuntu16.04_amd64.deb mysql-client_5.7.15-1ubuntu16.04_amd64.deb mysql-community-server_5.7.15-1ubuntu16.04_amd64.deb mysql-server_5.7.15-1ubuntu16.04_amd64.deb

4. Error installing pip

Solution: You can use the following command instead:

sudo apt-get install python-pip python-dev build-essential

sudo pip install –upgrade pip

sudo pip install –upgrade virtualenv

5. Error when installing Django

solve

Set timeout: sudo pip install django --default-timeout 100

Or use another download source: pip install web.py -i

6. Error when installing MySQL-python

错误：EnvironmentError: mysql_config not found

solve:

sudo apt-get install libmysqld-dev

Install MySQL-python: pip install MySQL-python

7. Update the Python library

pip install –upgrade 库名
