Ubuntu下安装PHP

安装apache2:sudo apt-get install apache2。查看是否成功:http://localhost/
安装PHP5:sudo apt-get install php5
sudo apt-get install libapache2-mod-php5(根据俺的实际测试,这一步似乎不用做了,在上一步已经安装好了,不过还是建议你copy/paste一下这条命令)
sudo /etc/init.d/apache2 restart 测试PHP5是否安装成功
sudo gedit /var/www/testphp.php
在里面写入,然后在Firefox中打开: http://localhost/testphp.php

安装mysql:sudo apt-get install mysql-server

MySql初始只允许本机(127.0.0.1)连接,如果想多台机子使用或者向Internet开放的话,编辑/etc/mysql/my.cnf
sudo gedit /etc/mysql/my.cnf
找到bind-address = 127.0.0.1,用#注释掉,象这样:#bind-address = 127.0.0.1

MySql默认没有设置root密码,本机的root用户也没有密码,有风险是吧,这样
mysqladmin -u root password your-new-password
mysqladmin -h root@local-machine-name -u root -p password your-new-password(这里我怎么也连接不上mysql服务器,最后在mysql-admin里面改的)
sudo /etc/init.d/mysql restart

安装MYSQL Administrator:sudo apt-get install mysql-admin

安装MYSQL for Apache HTTP Server
sudo apt-get install libapache2-mod-auth-mysql
sudo apt-get install php5-mysql

(sudo apt-get install phpmyadmin)

要让PHP与MySql一起工作,编辑
sudo gedit /etc/php5/apache2/php.ini
取消对;extension=mysql.so的注释,象这样

extension=mysql.so

保存文件,然后
sudo /etc/init.d/apache2 restart

测试:
http://localhost/phpmyadmin
