LNMP环境搭建——PHP篇

一、源码安装

1.编译安装

./configure  --prefix=/usr/local/php\
--with-config-file-path=/usr/local/php/etc --with-bz2 --with-curl \
--enable-ftp --enable-sockets --disable-ipv6 --with-gd \
--with-jpeg-dir=/usr/local --with-png-dir=/usr/local \
--with-freetype-dir=/usr/local --enable-gd-native-ttf \
--with-iconv-dir=/usr/local --enable-mbstring --enable-calendar \
--with-gettext --with-libxml-dir=/usr/local --with-zlib \
--with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-mysql=mysqlnd \
--enable-dom --enable-xml --enable-fpm --with-libdir=lib64 --enable-bcmath

make && make install

2.错误处理

[ERROR]-1

checking for ZLIB support... no 
checking if the location of ZLIB install directory is defined... yes 
configure: error: Cannot find libz

[ERROR]-2

checking whether to enable JIS-mapped Japanese font support in GD... no 
If configure fails try --with-vpx-dir=<DIR> 
configure: error: jpeglib.h not found.

【解决办法】

wget http://www.boutell.com/gd/http/gd-2.0.33.tar.gz
tar zxvf gd-2.0.33.tar.gz
cd gd-2.0.33
./configure --prefix=/usr/local/gd2
make
make instal

在网上找到了libjpeg，可以用这个库实现JPG图片的各种操作；下载：http://freeware.sgi.com/source/libjpeg/libjpeg-6b.tar.gz，
参考README安装库，大体步骤如下：

./configure
Make
Make install

[ERROR]-3

If configure fails try --with-xpm-dir=<DIR> 
configure: error: freetype-config not found.

[ERROR]-4

checking whether to enable JIS-mapped Japanese font support in GD... no 
configure: error: vpx_codec.h not found.

[Bzip2 Install]

tar -xzvf bzip2-1.0.6.tar.gz

进入解压后的目录：cd bzip2-1.0.6
为编译做准备，创建libbz2.so动态链接库(这一步很重要，安装python的时候如果没有这一步，python安装不上bz2模块)：

make -f Makefile-libbz2_so

编译安装： make && make install

二、RPM安装

[root@kallen ~]# rpm -ivh php-common-5.4.40-1.el6.remi.x86_64.rpm 
warning: php-common-5.4.40-1.el6.remi.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 00f97f56: NOKEY

三、YUM安装

1.PHP-5.4

php5.4于2012年5月8号发布,从php5.4.0开始php加入了一些新特色如：

• Traits支持
• 内置了一个简单的Web服务器
• 提供了数组简短语法
• 直接对函数返回值进行数组取值
• 最终删除魔术方法及安全模式

推荐使用 Webtatic EL6的YUM源来安装php5.4，我们首先安装Webtatic EL6 YUM源，关于YUM源的安装配置请参考《在RHEL6中配置YUM源》一文；

rpm -Uvh http://repo.webtatic.com/yum/el6/latest.rpm  

yum -y install php54w php54w-bcmath php54w-cli \
php54w-common php54w-devel php54w-fpm php54w-gd \
php54w-imap php54w-ldap php54w-mbstring php54w-mcrypt \
php54w-mysql php54w-odbc php54w-pdo php54w-pear \
php54w-pecl-igbinary php54w-xml php54w-xmlrpc \
php54w-opcache php54w-intl php54w-pecl-memcache 

如果安装失败，建议您先卸载以前的php再进行安装，使用

 yum remove php php-*

附带的php扩展列表：

[root@kallen ~]# yum install php54w-gd.x86_64

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

解决办法：

[root@kallen ~]# rpm -ivh t1lib-5.1.2-6.el6_2.1.x86_64.rpm 
warning: t1lib-5.1.2-6.el6_2.1.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

2.PHP-5.5

[root@kallen ~]# yum remove php  php-bcmath php-cli php-common  php-devel php-fpm    php-gd php-imap  php-ldap php-mbstring php-mcrypt php-mysql   php-odbc   php-pdo   php-pear  php-pecl-igbinary  php-xml php-xmlrpc

[root@kallen ~]# yum install php55w  php55w-bcmath php55w-cli php55w-common  php55w-devel php55w-fpm    php55w-gd php55w-imap  php55w-ldap php55w-mbstring php55w-mcrypt php55w-mysql   php55w-odbc   php55w-pdo   php55w-pear  php55w-pecl-igbinary  php55w-xml php55w-xmlrpc php55w-opcache php55w-intl php55w-pecl-memcache

四、版本测试

1.查看PHP版本信息

(1) 查看版本号

kallen@kallen:~$ php -v
PHP 5.5.9-1ubuntu4.11 (cli) (built: Jul  2 2015 15:23:08) 
Copyright (c) 1997-2014 The PHP Group

    with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies 

(2) 查看安装信息
在Apache的document root目录下编辑测试页面index.php，内容如下：

<?php
    phpinfo();
?>

通过http://localhost:port/php/index.php访问：

2.查看PHP已安装模块

kallen@kallen:~$ php -m

3.MySQL连接测试

<?php
    $link=mysql_connect(‘localhost‘,‘root‘,‘*‘);
    if(!$link)
        echo "Connection Error!";
    else
        echo "Connected Successfully!"
    mysql_close();
?>

未完续待！
