：盡量少yum安裝。
假定已經(jīng)安裝好了httpd，如果沒(méi)有就yum install httpd禾酱，注意還要安裝yum install httpd-devel
以下是步驟：
1. 安裝先決條件
yum install -y gcc gcc-c++ make automake autoconf gd file bison patch mlocate flex diffutils zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel libcurl libcurl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers openldap-devellibxslt-devel kernel-devel libtool-libs readline-devel gettext-devel libcap-devel php-mcrypt libmcrypt libmcrypt-devel recode-devel gmp-devel icu libxslt libxslt-devel php-devel
2. 下載php7.2.31.tar.gz科侈，到 /usr/src目錄, 解壓，進(jìn)入php源文件目錄
cd /usr/src
wget?https://www.php.net/distributions/php-7.2.31.tar.gz
tar -xvf php-7.2.31.tar.gz??
cd php-7.2.31/
3. 停止httpd服務(wù)
systemctl stop httpd.service
4. 編譯配置&安裝
./configure --help命令可以列出當(dāng)前可用的所有參數(shù)辅辩。
因?yàn)橐胊pache难礼，所以確認(rèn)一下apxs目錄
find / -name apxs
得到 /usr/bin/apxs ，如果沒(méi)有找到玫锋，安裝一下httpd-devel：yum intall httpd-devel
執(zhí)行以下命令進(jìn)行編譯配置：（編譯選項(xiàng)說(shuō)明見(jiàn)文末附件）
./configure --prefix=/usr/local/php --with-apxs2=/usr/bin/apxs --with-config-file-path=/usr/local/php/etc --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-pdo --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir= --enable-xml --enable-session --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --enable-maintainer-zts --with-xsl --enable-tokenizer
編譯配置完畢：

安裝：
make && make install
5. 配置php.ini
將安裝包的php.ini.product 復(fù)制到php安裝目錄
cp php.ini-production /usr/local/php/etc/php.ini
配置php.ini
date.timezone = PRC
expose_php=Off
6. 配置apache蛾茉，支持php
vim /etc/httpd/conf/httpd.conf
檢查有沒(méi)有添加 LoadModule php7_module /usr/lib64/httpd/modules/libphp7.so ，沒(méi)有就添加撩鹿。
Apache配置擴(kuò)展名解析成 PHP
在http.conf文件尾部加入：
<FilesMatch \.php$>
????SetHandler application/x-httpd-php
</FilesMatch>
7. 配置環(huán)境變量
新建php環(huán)境變量
touch /etc/profile.d/php.sh
打開(kāi)php.sh文件并寫(xiě)入：
PATH=$PATH:/usr/local/php/bin
導(dǎo)出
export PATH
使配置文件生效
source /etc/profile
查看php 版本谦炬，確認(rèn)已經(jīng)安裝成功
8. 啟動(dòng)apache
service httpd restart
在web目錄建phpinfo文件查看。
