PHP(Hypertxt Preprocessor，超文本预处理器)是一种通用的开源脚本语言，发明于1995年，它吸取了C语言、Java语言及Perl语言的很多优点，具有开源、免费、快捷、跨平台性强、效率高等优良特性，是目前Web开发领域最常用的语言之一。使用源码包的方式编译

安装PHP语言环境其实并不复杂，难点在于解决PHP的程序包和其他软件的依赖关系。为此需要先安装部署将近十个用于搭建网站页面的软件程序包，然后才能正式安装PHP程序。

yasm源码包是一款常见的开源汇编器

libgd源码包是用于提供图形处理的服务程序，在编译libgd源码包时，请记得写入的是jpeg、libpng、freetype、tiff、libvpx等服务程序在系统中的安装路径，即在上面安装过程中使用--prefix参数指定的目录路径

cd ..

tar zxvf libgd-2.1.0.tar.gz

cd libgd-2.1.0

./configure --prefix=/usr/local/libgd --enable-shared --with-jpeg=/usr/local/jpeg --with-png=/usr/local/libpng --with-freetype=/usr/local/freetype --with-fontconfig=/usr/local/freetype --with-xpm=/usr/ --with-tiff=/usr/local/tiff --with-vpx=/usr/local/libvpx

![ecf0936f4ea20ca1a83bc4185e28a721.png][]

t1lib源码包是用于提供图片生成函数库的服务程序，安装后把/usr/lib64目录中的函数文件链接到/usr/lib目录中，以便系统能够顺利调取到函数文件：

cd ..

tar zxvf t1lib-5.1.2.tar.gz

cd t1lib-5.1.2

./configure --prefix=/usr/local/t1lib --enable-shared

make

make install

ln -s /usr/lib64/libltdl.so /usr/lib/libltdl.so

cp -frp /usr/lib64/libXpm.so\* /usr/lib/

![f5affca153936ccc73ac385999a42444.png][]

![691b64a25404d3b9491794d87160c316.png][]

此时终于把编译php服务源码包的相关软件包都已经安装部署妥当了。在开始编译php源码包之前，先定义一个名为LD\_LIBRARY\_PATH的全局环境变量，该环境变量的作用是帮助系统找到指定的动态链接库文件，这些文件是编译php服务源码包的必须元素之一。编译php服务源码包时，除了定义要安装到的目录以外，还需要依次定义配置php服务程序配置文件的保存目录、MySQL数据库服务程序所在目录、MySQL数据库服务程序配置文件所在目录，以及libpng、jpeg、freetype、libvpx、zlib、t1lib等服务程序的安装目录路径，并通过参数启动php服务程序的诸多默认功能：

cd ..

tar -zvxf php-5.5.14.tar.gz

cd php-5.5.14

export LD\_LIBRARY\_PATH=/usr/local/libgd/lib

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql\_config --with-mysql-sock=/tmp/mysql.sock --with-pdo-mysql=/usr/local/mysql --with-gd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/ --with-vpx-dir=/usr/local/libvpx/ --with-zlib-dir=/usr/local/zlib --with-t1lib=/usr/local/t1lib --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --enable-ctype

make

make install

![cca5d3413c006734e25d5edfa3188f43.png][]

![e113aa3e2b6c54734f01ebfb69ebf713.png][]

![0df245d117c0b875d43b6cdcf3ea0ade.png][]

![a61da5feb4e198e1b75c165919be57ee.png][]

在php源码包程序安装完成后，需要删除当前默认的配置文件，然后将php服务程序目录中相应的配置文件复制过来：

rm -rf /etc/php.ini

ln -s /usr/local/php/etc/php.ini /etc/php.ini

cp php.ini-production /usr/local/php/etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

ln -s /usr/local/php/etc/php-fpm.conf /etc/php-fpm.conf

![b63c790c1daead0491029e3ec0bc114b.png][]

php-fpm.conf是php服务程序重要的配置文件之一，我们需要启用该配置文件中第25行左右的pid文件保存目录，然后分别将第148和149行的user与group参数分别修改为www账户和用户组名称：

vim /usr/local/php/etc/php-fpm.conf

25 pid = run/php-fpm.pid

148 user = www

149 group = www

![d18b18c1e8b00d378fb1f2ffaffaebf7.png][]

配置妥当后便可把用于管理php服务的脚本文件复制到/etc/rc.d/init.d中了。为了能够执行脚本，请记得为脚本赋予755权限。最后把php-fpm服务程序加入到开机启动项中：

cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm

chmod 755 /etc/rc.d/init.d/php-fpm

chkconfig php-fpm on

![3771b2601f0b53b05bde5373a7401f91.png][]

由于php服务程序的配置参数直接会影响到Web服务服务的运行环境，因此，如果默认开启了一些不必要且高危的功能(如允许用户在网页中执行Linux命令)，则会降低网站被\*\*\*的难度，\*\*\*人员甚至可以拿到整台Web服务器的管理权限。因此我们需要编辑php.ini配置文件，在305行的disable\_functions参数后面追加上要禁止的功能

vim /usr/local/php/etc/php.ini

305 disable\_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell\_exec,proc\_open,proc\_get\_status,ini\_alter,ini\_alter,ini\_restor e,dl,openlog,syslog,readlink,symlink,popepassthru,stream\_socket\_server,escapeshellcmd,dll,popen,disk\_free\_space,checkdnsrr,checkdnsrr,g etservbyname,getservbyport,disk\_total\_space,posix\_ctermid,posix\_get\_last\_error,posix\_getcwd,posix\_getegid,posix\_geteuid,posix\_getgid,po six\_getgrgid,posix\_getgrnam,posix\_getgroups,posix\_getlogin,posix\_getpgid,posix\_getpgrp,posix\_getpid,posix\_getppid,posixgetpwnam,posix getpwuid,posix\_getrlimit,posix\_getsid,posix\_getuid,posix\_isatty,posix\_kill,posix\_mkfifo,posix\_setegid,posix\_seteuid,posixsetgid,posix setpgid,posix\_setsid,posix\_setuid,posix\_strerror,posix\_times,posix\_ttyname,posix\_uname

![e6c0ce2bb1b191f047281586160dcb62.png][]

辑Nginx服务程序的主配置文件，把第2行的井号(\#)删除，然后在后面写上负责运行Nginx服务程序的账户名称和用户组名称；在第45行的index参数后面写上网站的首页名称。最后是将第65～71行参数前的井号(\#)删除来启用参数，主要是修改第69行的脚本名称路径参数，其中$document\_root变量即为网站信息存储的根目录路径，若没有设置该变量，则Nginx服务程序无法找到网站信息，因此会提示“404页面未找到”的报错信息。在确认参数信息填写正确后便可重启Nginx服务与php-fpm服务。

vim /usr/local/nginx/conf/nginx.conf

2 user www www;

45 index index.html index.htm index.php;

65 location ~ .php$ \{

66 root html;

67 fastcgi\_pass 127.0.0.1:9000;

68 fastcgi\_index index.php;

69 fastcgi\_param SCRIPT\_FILENAME $document\_root$fastcgi\_script\_name;

70 include fastcgi\_params;

71 \}

退出

systemctl restart nginx

systemctl restart php-fpm
