全面解析ubuntu下安装php、pear

前言

因为在windows下搞pear没有成功，老出现无缘无故的问题，所以今天用ubuntu搭建了一个php。众所周知开源代码和linux总是有无懈的缘分，而我作为一个开源的忠实粉丝，却还抱着windows系统不放，总有些惭愧，下一个wamp毫无技术可言就搞定了。少说废话，下面就开始。

ubuntu搭建php

① apache2

sudo apt-get install apache2

…大概几秒钟时间

打开浏览器输入http://localhost/

it works总是令人那么激动，只是你还有很多东西要做

② PHP5

sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart

然后php应该被安装到了/etc/php5/下

试试 php -v

查询到PHP 5.4.6

③ 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 在前面加一个’#’注释掉

④ MySql Administrator

sudo apt-get install mysql-admin

不知道为啥这个命令没有成功，如果你也不行，可以试下下面的命令

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

重启apache

sudo /etc/init.d/apache2 restart

打开浏览器输入http://localhost/phpmyadmin，我在这里输的时候，出现了一个问题

Not Found The requested URL /phpmyadmin/ was not found on this server. Apache/2.2.14 (Ubuntu) Server at localhost Port 80

然后各种纠结，百度了以后才知道得让phpAdministrator和php建立一个软连接

打开var/www

sudo ln -s /usr/share/phpmyadmin

⑤ pear

下载pear在php中是一个很简单的事情，只要输入一行代码

curl -o go-pear.php http://pear.php.net/go-pear

如果你没有按curl，请输入一行命令

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

重启下服务器

sudo /etc/init.d/apache2 restart

⑥ 运行go-pear.php

找到go-pear.php

php go-pear.php

** WARNING! Old version found at /usr/local/php5/bin, please remove it or be sure to use the new /usr/local/php5/bin/pear command
The ‘pear’ command is now at your service at /usr/local/php5/bin/pear
** The ‘pear’ command is not currently in your PATH, so you need to
** use ‘/usr/local/php5/bin/pear’ until you have added
** ‘/usr/local/php5/bin’ to your PATH environment variable.
Run it without parameters to see the available actions, try ‘pear list’
to see what packages are installed, or ‘pear help’ for help.
