二、安装PHP（编译安装）
1.下载PHP php-7.4.15
wget https://www.php.net/distributions/php-7.4.15.tar.gz

把它移动到usr/local文件下操作
mv php-7.4.15.tar.gz /usr/local/php-7.4.15.tar.gz

切换文件目录
cd /usr/local/

解压文件
tar --bzip -xvf /usr/local/php-7.4.15.tar.gz

切换文件目录
cd php-7.4.15

2.安装编译工具和库
yum -y install gcc gcc-c++
yum -y install libxml2-devel openssl-devel curl-devel libjpeg-devel libpng-devel libicu-devel freetype-devel openldap-devel openldap openldap-devel

3.创建用户组和用户
groupadd www
useradd -g www www

4.编译
./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--with-fpm-user=www \
--with-fpm-group=www \
--with-curl \
--with-MySQL=/usr/local/mysql \
--with-freetype-dir=/user/local/freetype \
--enable-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \
--with-libdir=lib64 \
--with-libxml-dir \
--with-mysqli \
--with-openssl \
--with-pcre-regex \
--with-pdo-mysql \
--with-pdo-sqlite \
--with-pear \
--with-png-dir=/user/local/libpng \
--with-jpeg-dir=/user/local/libjpeg \
--with-xmlrpc \
--with-xsl \
--with-zlib \
--with-zlib-dir=/user/local/zlib \
--with-bz2 \
--with-mhash \
--with-zip \
--enable-fpm \
--enable-bcmath \
--enable-libxml \
--enable-inline-optimization \
--enable-mbregex \
--enable-mbstring \
--enable-opcache \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \
--enable-xml \
--enable-zip \
--enable-fpm

make
make install

5.报错处理
a.No package ‘oniguruma‘ found

yum install oniguruma-devel

b.No package ‘libzip‘ found
yum remove libzip
wget https://libzip.org/download/libzip-1.3.2.tar.gz
tar -zxvf libzip-1.3.2.tar.gz
cd libzip-1.3.2
./configure
make && make install

cd /usr/local/lib
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/"指定PKG_CONFIG_PATH

三、yum安装
yum仓库包升级更换成PHP7的rpm包
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

yum -y install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64
yum -y install php70w-fpm php70w-opcache
systemctl start php-fpm
php -v
