一、解决依赖

yum -y install php-mcrypt libmcrypt libmcrypt-devel php-pear libxml2 libxml2-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype-devel

二、下载PHP

可以从 https://www.php.net/downloads.php 页面下载 PHP 的最新 Stable 版本，解压缩，进入源码目录。

三、配置PHP

[root@mysite ~]# tar -zxf php-7.4.8.tar.gz -C /usr/local/src/
[root@mysite ~]# cd /usr/local/src/php-7.4.8/
[root@mysite ~]# ./configure  --prefix=/usr/local/php --with-config-file-path=/usr/local/php/ --enable-fpm --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --enable-ftp --enable-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts

#出现的错误

#error: Package requirements (sqlite3 > 3.7.4) were not met
error: Package requirements (sqlite3 > 3.7.4) were not met
No package 'sqlite3' found
若看到上面的报错，非常简单：
yum install libsqlite3x-devel -y

#error: Package requirements (oniguruma) were not met
error: Package requirements (oniguruma) were not met
No package 'oniguruma' found
若看到上面的报错，非常简单：
yum install oniguruma-devel -y

另外一个错误
configure: error: Package requirements (libcurl >= 7.15.5) were not met:
No package 'libcurl' found
yum install libcurl-devel

configure: error: Package requirements (libpng) were not met:
No package 'libpng' found
yum install -y libpng-devel

#配置通过后，提示的警告

Thank you for using PHP.

configure: WARNING: unrecognized options: --with-freetype-dir, --with-jpeg-dir, --with-png-dir, --with-libxml-dir, --with-mcrypt, --enable-gd-native-ttf, --enable-zip

四、编译安装

[root@mysite php-7.4.8]# make -j 4 && make install

五、生成php配置文件：

[root@wordpress php-7.4.8]# cp /usr/local/src/php-7.4.8/php.ini-production /usr/local/php/php.ini

[root@wordpress php-7.4.8]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.conf

六、修改PHP-FPM配置文件：

[root@wordpress php-7.4.8]# vim /usr/local/php/etc/php-fpm.conf

改：21 user = nobody
为：21 user = nginx

改：24 group = nobody
为：24 group = nginx

七、启动PHP

生成php-fpm启动脚本

[root@wordpress php-7.4.8]# cp /usr/local/src/php-7.4.8/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

开机启动

[root@wordpress php-7.4.8]# chmod +x /etc/init.d/php-fpm
[root@wordpress php-7.4.8]# chkconfig --add php-fpm
[root@wordpress php-7.4.8]# chkconfig php-fpm on

尝试启动

[root@wordpress php-7.4.8]# /etc/init.d/php-fpm start
Starting php-fpm  done
[root@wordpress php-7.4.8]# netstat -antup | grep php-fpm
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      26687/php-fpm: mast 

测试php连接mysql

<?php
 $servername = "localhost";
 $username = "root";
 $password = "******";
// 创建连接
$conn = new mysqli($servername, $username, $password);
// 检测连接
if ($conn->connect_error) {
 die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
 phpinfo();
?>

#怀疑是nginx配置文件出现问题：

#检查nginx配置文件：

确实没有添加绝对路径，因此添加上：

[root@wordpress php-7.4.8]# vim /usr/local/nginx/conf/nginx.conf

    location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html/$fastcgi_script_name;
        include        fastcgi_params;
    }

#然后又出现的问题：

#连接失败：no such file or directory ，原因在于php.ini文件当中并没有配好mysql.sock的路径，因此：

[root@mysite ~]# vim /usr/local/php/php.ini
mysqli.default_socket = /usr/local/mysql/mysql.sock
pdo_mysql.default_socket= /usr/local/mysql/mysql.sock

重启

[root@mysite ~]# /etc/init.d/php-fpm restart

八、nginx导致index.php文件不能正常查看

PS.如是出现nginx不能正常关闭的情况，请强制关闭。

[root@wordpress ~]# pkill -9 nginx

九、PHP版本显示不正确

[root@LNMP ~]# php -v
PHP 5.4.16 (cli) (built: Apr  1 2020 04:07:17) 
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
[root@LNMP ~]# /usr/local/php/bin/php -v  #正确的路径
PHP 7.4.8 (cli) (built: Mar  9 2023 07:50:45) ( ZTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies

找到/usr/bin下的存在的php文件，然后一个个删除

[root@LNMP ~]# find /usr/bin/ -type f -name '*php*'
/usr/bin/php-cgi
/usr/bin/php
/usr/bin/phpize
[root@LNMP ~]# cd /usr/bin
[root@LNMP bin]# rm -rf ./php
[root@LNMP bin]# rm -rf ./php-cgi
[root@LNMP bin]# rm -rf ./phpize

添加新的变量

[root@LNMP bin]# vim /etc/profile.d/php71.sh
添加：export PATH="/usr/local/php/bin:$PATH"

[root@LNMP bin]# chmod +x /etc/profile.d/php71.sh
[root@LNMP bin]# source /etc/profile.d/php71.sh

[root@LNMP bin]# php -v     #版本能正确显示
PHP 7.4.8 (cli) (built: Mar  9 2023 07:50:45) ( ZTS )
