PHP linux 安装手册

1、下载php 7.2.12版本
https://www.php.net/downloads.php
百度网盘
https://pan.baidu.com/s/11cCfc8bMLdWOfFUObiVREw
提取码：yzcr

2、解压 

tar -zxvf php7.2.12.tar.gz

3、安装依赖：
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

4、编译 php7.2不支持 --with-mcrypt, --enable-gd-native-ttf，把这两个选项删除掉。

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-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-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

执行编译:
# 耗时大概40分钟左右
>make

>make install 

5、编译完成之后，我们添加PHP命令到环境变量里
vim /etc/profile
>>>
PATH=$PATH:/usr/local/php/bin
export PATH

6、检查：
php -v

php -i |less 查看配置文件在哪里，编译参数
php -m |less 查看php加载的模块
