ubuntu14 安装apache和php环境

第一步：安装apache2

sudo apt-get install apache2

可能会出现如下错误：

AH00558: apache2: Could not reliably determine the server's fully qualified domain name,
using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

这个是没有指定ServerName的：http://stackoverflow.com/questions/5856205/starting-httpd-httpd-could-not-reliably-determine-the-servers-fully-qualified

Edit Apache2 conf file : vim /etc/apache2/apache2.conf
Insert the following line at the apache2.conf: ServerName localhost
Restart Apache2: apache2ctl restart or /etc/init.d/apache2 restart

但是我本地装了nginx,他可能会出现如下错误：

# /etc/init.d/httpd restart
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

出现这个情况，有两个解决方案，网上很多关于二者共存的，可是我只是用来学习的，还是用绕道的方式，把apache的端口改掉

sudo cp /etc/apache2/ports.conf /etc/apache2/ports.conf_backup
sudo gedit /etc/apache2/ports.conf

搜寻

Listen 80

替换成

Listen 90

sudo /etc/init.d/apache2 restart

浏览 http://localhost:90/html/出现 It works!  apache安装成功

第二步：安装php环境

sudo apt-get install libapache2-mod-php5 php5 php5-gd php5-mysql

重启apache：

sudo /etc/init.d/apache2 restart

下面进行测试：

sudo gedit /var/www/html/test.php

添加如下代码：

<?php echo phpInfo();?>

浏览：http://localhost:90/html/test.php

这地方很多博客都在www目录下编辑，浏览也没有html，我本地是浏览不成功的
