安装authpuppy ,做环境检测时报错如下：

解决方法：
安装php 模块及一些软件包：

[root@authppy src]# yum install -y libxslt libxslt-devel  php-pdo php-xml php-mbstring php-process

关闭php 相应参数：

[root@authppy src]# vi /usr/local/php/etc/php.ini
short_open_tag = Off
magic_quotes_gpc = Off

错误ARC 的解决方法：

[root@authppy src]# wget http://pecl.php.net/get/APC-3.1.13.tgz
[root@authppy src]# tar zxf APC-3.1.13.tgz 
[root@authppy src]# cd APC-3.1.13

准备工作：ubuntu中安装Apache2，php5，mysql，及 postgres。具体的步骤可以去搜下，一般的多是apt-get install 就OK。postgres 安装名为postgresql

具体还可以参照authpuppy官方doc ，http://www.authpuppy.org/doc/Getting_Started。这个一定要看！写的很详细。
1.首先在authpuppy 官网下载源码http://www.authpuppy.org/。找到download，去下载authpuppy-1.0.0-stable.tgz 该版本。

2.将authpuppy-1.0.0-stable.tgz代码解压到/var/www/目录下后，访问http://localhost/authpuppy/web/ 会访问到preinstall.php，下面开始安装。先按照http://www.authpuppy.org/doc/Getting_Started中，将PostgreSQL数据建立成功。成功后，按照Getting_Started帮助手册，修改/etc/apache2/sites-available/default 这个文件，内容如下：

<VirtualHost *:80>
       ServerAdmin webmaster@localhost
       ServerName authpuppy.localhost
       ServerAlias authpuppy.test

       <span style="color: #ff0000;">#DocumentRoot /var/www/authpuppy/web/</span>  <br>　　　　DocumentRoot /var/www/     <br>　　　　DirectoryIndex index.php
       <Directory /var/www/authpuppy/web/>
               Options Indexes FollowSymLinks MultiViews
               AllowOverride All
               Order allow,deny
               allow from all
       </Directory>

       Alias /sf /var/www/authpuppy/lib/vendor/symfony/data/web/sf
       <Directory "/var/www/authpuppy/lib/vendor/symfony/data/web/sf">
               AllowOverride All
               Allow from All
       </Directory>

       <span style="color: #ff0000;">#ErrorLog /var/log/apache2/authpuppy/error.log
</span>　　　　ErrorLog /var/log/apache2/error.log<br>　　 
       # Possible values include: debug, info, notice, warn, error, crit,
       # alert, emerg.
       LogLevel warn

       <span style="color: #ff0000;">#CustomLog /var/log/apache2/authpuppy/access.log combined
</span>　　　　CustomLog /var/log/apache2/access.log combined<br>　　<br>　　　　 
  </VirtualHost>

加红色部分为Getting_Started中给的原样，我针对这个做了部分修改。关于两个log，因为/var/log/apache2/目录下没有authpuppy 这个文件，所以加这个的话Apache重启时会失败，所以将其去掉（或者你自己添加上也可以）。

$ sudo service apache2 restart

重启Apache，访问http://localhost/authpuppy/web/ .会出现第一个页面，点击let's go按钮。然后进到下一个页面上，这里会提示你什么文件没有可写权限或者没有安装某个php的扩展，按照上面提示做就可以了！还有注意一点。有时候点击let's go 就会出错，页面就访问失败了！这里可以将/authpuppy/web/installed.txt 这个删除掉。就可以了！处理好后点击next。进到连接数据库页面。我刚开始这个页面总访问不进来。这时按照http://www.authpuppy.org/doc/Getting_Started，将环境设置了一边后就可以访问了。具体的原因没有查明。然后就是与数据库连接，数据库选择postsql，注意用户名密码是否正确。过了这个页，基本上就是成功了。

用自己的话写的比较粗略，只供自己下次再搭建该环境时有个提醒。（这次就是第二次，又花费了一天多- -），第一次搭建步骤都忘了，所以想记录一下过程。主要是参考这两个链接：

安装与配置authpuppy:

源码包：

#wget https://launchpad.net/authpuppy/trunk/1.0.0-stable/+download/authpuppy-1.0.0-stable.tgz

#cd /home
tar -xvf authpuppy-1.0.0-stable.tgz

#// apache配置一个虚拟域名(比如http://authpuppy.localhost/)指向目录 /home/authpuppy

打开http://authpuppy.localhost/
按提示完成对依赖包的安装(Requirements下的最好都安装), 如下：
依赖库: // 主要是PHP扩展包

APCu:

#wget http://pecl.php.net/get/apcu-4.0.6.tgz
#phpize
#./configure --with-php-config=/usr/local/php/bin/php-config --enable-apcu --enable-apc-bc
#make -s
#make install
#vi /usr/local/php/etc/php.ini
extension=apcu.so

Permissions下出现红色部分，则需要做下面操作：

#chmod a+w authpuppy/ -R
#//自动创建authpuppy.yml

然后：

// 必须需要启用pdo_mysql,因为symfony的用的是PDO, 灵感来自http://bbs.csdn.net/topics/390036982
#cd php-5.6.2/ext/pdo_mysql
#phpize
#./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql/
#make -s
#make install

#mysqladmin -uroot -p create authpuppy
#mysql -uroot -p

#create user 'authpuppy'@'localhost' identified by 'authpuppydev';
#grant all privileges on authpuppy.* to 'authpuppy'@'localhost' with grant option;

接着按界面来走就好了。

sudo apt-get install apache2
sudo apt-get install php5

These following commands are optionnals but may be help a lot.
sudo apt-get update
sudo apt-get upgrade --show-upgraded
end of optionnal commands

sudo apt-get install postgresql postgresql-contrib (if you plan to use postresql database)
or
sudo apt-get install mysql-server (if you plan to use mysql database)

*** Both of them (mysql or postgres) are on the same level. Using one of them is only a question of choice ***

sudo apt-get install php5-dev
sudo apt-get install php-pear
sudo apt-get install apache2-prefork-dev build-essential
pecl install apc

in the dynamic extensions part of php.ini
add extension=apc.so in /etc/php5/apache2/php.ini
add extension=apc.so in /etc/php5/cli/php.ini

change short_open_tag=on to off in php.ini (apache dir and cli dir)

by doing
sudo nano /etc/php5/apache2/php.ini
ctrl o ctrl x when everything is written

sudo nano /etc/php5/cli/php.ini
ctrl o ctrl x when everything is written

add subdirectory "authpuppy" in /var/log/apache2
by doing this
cd /var/log/apache2
sudo mkdir authpuppy
cd /

sudo a2enmod rewrite
sudo /etc/init.d/apache2 restart

sudo apt-get install php5-pgsqlp (if you are using postgresql database)
sudo apt-get install php5-mysql (if you are using mysql database)

To make sure that pdo and pdo-mysql or pdo and pdo-pgsql are correctly installed
type this command

sudo php -m

and you should see them among all the php5 modules installed.

sudo apt-get install php5-curl
sudo apt-get install php5-xsl

download last version of authpuppy, copy it in the root tmp dir

cd /tmp
sudo tar xvzf authpuppy--_.tgz
sudo mv authpuppy /var/www/

add these following lines in httpd.conf in the /etc/apache2 directory
by doing
sudo nano /etc/apache2/httpd.conf and copy and paste these following lines

ctrl-o ctrl-x

Note : To make sure that authpuppy will be launched correctly, it can help that the hosts
file in /etc directory have this line

127.0.0.1 authpuppy.localhost

by doing
sudo nano /etc/hosts
ctrl-o ctrl-x
Now, do these commands in terminal :

cd /var/www/authpuppy

sudo chown -R a+w config
sudo chown -R www-data cache
sudo chown -R www-data log
sudo chown -R www-data data
sudo chown -R www-data plugins
sudo chown -R www-data web

cd /

sudo -s -u postgres
createuser authpuppy --pwprompt
type n for each questions
createdb authpuppy --encoding=UTF-8 --owner=authpuppy

Type exit

if you are using mysql

user@yourserver $> mysqladmin -uroot -p create authpuppy
Enter password: #Enter the root password
user@yourserver $> mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 45
Server version: 5.0.51a-3ubuntu5.5 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> create user 'authpuppy'@'localhost' identified by 'authpuppydev';
Query OK, 0 rows affected (0.21 sec)

mysql> grant all privileges on authpuppy.* to 'authpuppy'@'localhost'
with grant option;
Query OK, 0 rows affected (0.02 sec)

Type exit

Everything's may be ok now.

To make sure that you have a proper and clean installation
type :

symfony cc

in the /var/wwww/authpuppy directory.

Use your internet browser and type : http://authpuppy.localhost

Do not use chromium browser, there's a bug in it about opening local web server
