LiNUX安装PHP7.X PHP版本：7.2.12 下载地址：http://cn2.php.net/get/php-7.2.12.tar.bz2/from/this/mirror

推荐（免费）：PHP7

安装前准备，避免在安装PHP依赖包时报错：configure: error: mcrypt.h not found. Please reinstall libmcrypt. 添加 epel 源centos 7.x

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

此处我将PHP 下载到 /usr/local 下，进入此目录下

tar -zxvf php7.2.12tar.gz

进入目录

cd php-7.2.12

安装PHP依赖包

yum install gcc libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

如果依赖包安装好，就将以下整段复制编译，PHP目录到 /usr/local/php;

./configure \--prefix=/usr/local/php \--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=nginx  \--with-fpm-group=nginx \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared  \--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir  \--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets  \--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache

编译并安装：

make && make install

编译完成之后，我们添加PHP命令到环境变量里

vim  /etc/profile

在文件末尾加入：

PATH=$PATH:/usr/local/php/binexport PATH

要使改动立即生效执行

source /etc/profile

查看PHP 版本

php -v

这时候，nginx还是不支持php的，它需要php-fpm来处理两者的依赖关系，所以我们要胚子php-fpm

tar -zxvf php7.2.12tar.gz0

启动php-fpm

tar -zxvf php7.2.12tar.gz1

nginx和php-fpm整合 编辑/usr/local/nginx/nginx.conf

修改如下： 红框中 “#”号去掉 添加红框中内容 修改内容，如下（找到如下开头内容）

这里我将配置文件换到我自定义的文件中去，不做以上修改； 只在文件末尾加入

tar -zxvf php7.2.12tar.gz2

创建文件夹，并创建编辑 app.conf 文件

tar -zxvf php7.2.12tar.gz3

编辑内容：

tar -zxvf php7.2.12tar.gz4
