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=$path:/usr/local/php/binexport path
要使改动立即生效执行
source /etc/profile
查看php 版本
php -v
这时候，nginx还是不支持php的，它需要php-fpm来处理两者的依赖关系，所以我们要胚子php-fpm
cp php.ini-production /etc/php.inicp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.confcp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpmchmod +x /etc/init.d/php-fpm
启动php-fpm
/etc/init.d/php-fpm start
nginx和php-fpm整合
编辑/usr/local/nginx/nginx.conf
修改如下：
红框中 “#”号去掉
添加红框中内容
修改内容，如下（找到如下开头内容）
这里我将配置文件换到我自定义的文件中去，不做以上修改；
只在文件末尾加入
client_max_body_size 200m;include vhosts/*.conf;
创建文件夹，并创建编辑 app.conf 文件
mkdir vhostsvim app.conf
编辑内容：
server{ listen 80; server_name 39.105.186.95 vv.vv.com; index index.php index.html; root /home/html/angel; location ~ .*\.(php|php7)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.html; include /usr/local/nginx/conf/fastcgi.conf; client_max_body_size 1000m; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 7d; } location ~ .*\.(js|css)?$ { expires 1h; } if (!-e $request_filename) { rewrite ^/index.php(.*)$ /index.php?s=$1 last; rewrite ^(.*)$ /index.php?s=$1 last; break; }}
