在 CentOS 7.x / Fedora 21 上面体验 PHP 7.0
在CentOS/Fedora上安装PHP 7
让我们来看看怎样在CentOS 7和Fedora 21安装PHP7。为了安装PHP7,我们首先需要克隆php-src 仓库。当克隆工作完成,我们再配置和编译它。进行下一步之前,我们要确保已经在LInux系统下安装了如下的组件,否则PHP编译会返回错误中止。
- Git
- autoconf
- gcc
- bison
所有上面提到的要求可以使用Yum软件包管理器安装。以下一条命令即可完成:
yum install git autoconf gcc bison
准备好开始安装PHP7了吗?让我们先创建一个PHP7目录,作为你的当前工作目录。
mkdir php7
cd php7
现在克隆php-src仓库,在终端里运行下面的命令。
git clone https://git.php.net/repository/php-src.git
工作应该会在几分钟后完成,这里是一个样例输出,你应该会在任务完成时看见。
[root@localhost php7]# git clone https://git.php.net/repository/php-src.git
Cloning into 'php-src'...
remote: Counting objects: 615064, done.
remote: Compressing objects: 100% (127800/127800), done.
remote: Total 615064 (delta 492063), reused 608718 (delta 485944)
Receiving objects: 100% (615064/615064), 152.32 MiB | 16.97 MiB/s, done.
Resolving deltas: 100% (492063/492063), done.
让我们来配置,编译PHP7,在终端运行下面的命令,开始配置工作:
cd php-src
./buildconf
下面是./buildconf命令的样例输出。
[root@localhost php-src]# ./buildconf
buildconf: checking installation...
buildconf: autoconf version 2.69 (ok)
rebuilding aclocal.m4
rebuilding configure
rebuilding main/php_config.h.in
使用下面的命令,继续配置进程:
./configure
--prefix=$HOME/php7/usr
--with-config-file-path=$HOME/php7/usr/etc
--enable-mbstring
--enable-zip
--enable-bcmath
--enable-pcntl
--enable-ftp
--enable-exif
--enable-calendar
--enable-sysvmsg
--enable-sysvsem
--enable-sysvshm
--enable-wddx
--with-curl
--with-mcrypt
--with-iconv
--with-gmp
--with-pspell
--with-gd
--with-jpeg-dir=/usr
--with-png-dir=/usr
--with-zlib-dir=/usr
--with-xpm-dir=/usr
--with-freetype-dir=/usr
--with-t1lib=/usr
--enable-gd-native-ttf
--enable-gd-jis-conv
--with-openssl
--with-mysql=/usr
--with-pdo-mysql=/usr
--with-gettext=/usr
--with-zlib=/usr
--with-bz2=/usr
--with-recode=/usr
--with-mysqli=/usr/bin/mysql_config
这会花去不少的时间,当完成后你应该会看到如下面的输出:
creating libtool
appending configuration tag "CXX" to libtool
Generating files
configure: creating ./config.status
creating main/internal_functions.c
creating main/internal_functions_cli.c

Thank you for using PHP.

运行下面的命令,完成编译过程。
make
“make”命令的样例输出如下所示:
Generating phar.php
Generating phar.phar
PEAR package PHP_Archive not installed: generated phar will require PHP's phar extension be enabled.

Build complete.
Don't forget to run 'make test'.
活儿干完了,该安装PHP7了,运行下面的命令安装它。
make install
成功安装的进程的样例输出应该像这样:

You may want to add: /root/php7/usr/lib/php to your php.ini include_path
/root/php7/php-src/build/shtool install -c ext/phar/phar.phar /root/php7/usr/bin
ln -s -f /root/php7/usr/bin/phar.phar /root/php7/usr/bin/phar
Installing PDO headers: /root/php7/usr/include/php/ext/pdo/
恭喜你,PHP7已经安装在你的Linux系统上了。安装完后,进入PHP7安装文件里的sapi/cli里面。
cd sapi/cli
验证一下PHP的版本。
[root@localhost cli]# ./php -v

总结
PHP 7也添加到了remi仓库,这个即将到来的版本主要关注执行效率的提升,它的新特性致力于使PHP较好满足现代编程的需求和趋势。PHP 7.0将会有许多新的特性、丢弃一些老版本的东西。在接下来的日子里,我们希望看到新特性和弃用功能的具体情况。希望你喜欢!
