下载php源码安装包

[root@krist phpdir]# wget https://www.php.net/distributions/php-7.4.9.tar.gz

解压安装包并添加用户和组

[root@krist phpdir]# tar zxvf php-7.4.9.tar.gz
[root@krist phpdir]# groupadd www
[root@krist phpdir]# useradd -M -g www -s /sbin/nologin www

进入目录开始编译

[root@krist phpdir]# cd php-7.4.9/
[root@Krist php-7.4.9]# export LD_LIBRARY_PATH=/usr/local/libgd/lib
[root@Krist php-7.4.9]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql-sock=/tmp/mysql.sock --with-pdo-mysql=/usr/local/mysql --with-gd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/ --with-vpx-dir=/usr/local/libvpx/ --with-zlib-dir=/usr/local/zlib --with-t1lib=/usr/local/t1lib --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --enable-ctype --with-apxs2=/usr/local/httpd/bin/apxs

可能出现的错误1：

configure: error: Package requirements (sqlite3 > 3.7.4)

解决：

yum -y install sqlite-devel

可能出现的错误2：

No package 'oniguruma' found

解决：

[root@Krist phpdir]# wget https://github.com/kkos/oniguruma/archive/v6.9.4.tar.gz -O oniguruma-6.9.4.tar.gz 
[root@Krist phpdir]# tar zxf oniguruma-6.9.4.tar.gz 
[root@Krist phpdir]# cd oniguruma-6.9.4/
[root@Krist oniguruma-6.9.4]# ./autogen.sh 
[root@Krist oniguruma-6.9.4]# ./configure --prefix=/usr/local/oniguruma --libdir=/lib64
[root@Krist oniguruma-6.9.4]# make && make install

可能出现的错误3：

configure: error: Please reinstall the libzip distribution

需要手动安装最新版本libzip，先编译安装最新版cmake，github：https://github.com/Kitware/CMake/releases

cd /usr/local/src
wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.tar.gz
tar -zxvf cmake-3.14.3.tar.gz
cd cmake-3.14.3
./bootstrap
make && make install

 再编译安装libzip

yum remove libzip -y
cd /usr/local/src
wget https://libzip.org/download/libzip-1.5.2.tar.gz
tar -zxvf libzip-1.5.2.tar.gz
cd libzip-1.5.2
mkdir build
cd build
cmake ..
make && make install

编译完成后测试并安装：

[root@krist php-7.4.9]# make test
[root@krist php-7.4.9]# make -j2 && make -j2 install

完成后添加环境变量：

[root@krist /]# vi /etc/profile
[root@krist /]# cat /etc/profile |tail -n 1
export PATH=$PATH:/usr/local/php/bin

为PHP提供配置文件：

[root@Krist php-7.4.9]# cp php.ini-production /usr/local/php/etc/php.ini
[root@Krist php-7.4.9]# ln -s /usr/local/php/etc/php.ini /etc/php.ini
[root@Krist php-7.4.9]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@Krist php-7.4.9]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
[root@Krist php-7.4.9]# ln -s /usr/local/php/etc/php-fpm.conf /etc/php-fpm.conf

修改php-fpm配置文件-www.conf

[root@Krist /]# cd /usr/local/php/etc/php-fpm.d/
[root@Krist php-fpm.d]# vim www.conf
user = www
group = www
[root@Krist php-fpm.d]# cd ..
[root@Krist etc]# vim php-fpm.conf
pid = run/php-fpm.pid

加入开机启动文件：

[root@Krist etc]# cd /www/phpdir/php-7.4.9/
[root@Krist php-7.4.9]# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
[root@Krist php-7.4.9]# chmod 755 /etc/rc.d/init.d/php-fpm 
[root@Krist php-7.4.9]# chkconfig php-fpm on

PHP-FPM与NGINX的整合

[root@krist etc]# vim /usr/local/nginx/conf/nginx.conf  //修改nginx配置文件的如下两个地方
[root@Krist php-7.4.9]# cat -n /usr/local/nginx/conf/nginx.conf | awk 'NR==2||NR<=46&&NR>=43||NR<=71&&NR>=65'
     2  user www www;
    43          location / {
    44              root   /var/www/html;
    45              index  index.html index.htm index.php;
    46          }
    65          location ~ \.php$ {
    66              root           /var/www/html;
    67              fastcgi_pass   127.0.0.1:9000;
    68              fastcgi_index  index.php;
    69              fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
    70              include        fastcgi_params;
    71          }
[root@krist etc]# systemctl restart nginx.service   //重启nginx

测试php模块是否能解析，输出phpinfo：

[root@Krist /]# service php-fpm start
[root@Krist /]# mkdir -p /var/www/html/
[root@Krist /]# cd /var/www/html/
[root@Krist html]# vim index.php
<?php
echo phpinfo();
?>

测试php连接mysql：实例 (MySQLi - 面向对象)

https://www.runoob.com/php/php-mysql-connect.html

<?php

$servername = "localhost"; 
$username = "username"; 
$password = "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"; 
?>

PHP-FPM与Apache整合

编辑Apache配置文件，加载php模块

[root@Krist /]# vim /usr/local/httpd/conf/http.conf
//修改以下内容，此处注意，php文件必须放前面，优先读取
<IfModule dir_module>
    DirectoryIndex index.php index.html
</IfModule>
在上两行内容下面添加两行内容
    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
在LoadModule下添加下面这行
LoadModule php7_module modules/libphp7.so

如果Apache安装目录的modules目录没有libphp7.so文件，说明安装编译php时少了--with-apxs2，需要重新编译安装php，不想重新编译，那你只能用Apache提供的其他方式运行PHP，比如：
1.使用Apache的mod_fcgid配合php-cgi运行(类似IIS + PHP-CGI)；
2.使用Apache的mod_proxy_fcgi配合php-fpm运行(类似Nginx + PHP-FPM)。

[root@Krist /]# cd /www/phpdir/php-7.4.9/
[root@Krist php-7.4.9]# find / -name "apxs"   //查看 apsx 所在路径
/usr/local/httpd/bin/apxs
/www/httpdir/httpd-2.4.46/support/apxs

重新编译php时，加入 apxs 路径参数，作用是促使生成 libphp7.so

[root@Krist php-7.4.9]# make clean  //清除make之后产生的.o文件以及一些编译过程中产生的中间文件（不确定对之前编译有无影响）
 find . -name \*.gcno -o -name \*.gcda | xargs rm -f

[root@Krist php-7.4.9]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-gd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/ --with-vpx-dir=/usr/local/libvpx/ --with-zlib-dir=/usr/local/zlib --with-t1lib=/usr/local/t1lib --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --enable-ctype --with-apxs2=/usr/local/httpd/bin/apxs --with-php-config=/usr/local/php/bin/php-config
[root@Krist php-7.4.9]# make && make install

以上的编译未编译安装mysqli扩展和pdo_mysql扩展，需要手动添加：

1、添加mysqli扩展

参考：https://blog.csdn.net/weixin_33816611/article/details/92310963

[root@Krist php-7.4.9]# cd ext/mysqli/
[root@Krist mysqli]# /usr/local/php/bin/phpize 
Configuring for:
PHP Api Version:         20190902
Zend Module Api No:      20190902
Zend Extension Api No:   320190902
[root@Krist mysqli]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/local/mysql/bin/mysql_config
[root@Krist mysqli]# make && make install

问题1： 在安装mysqli的时候，出现error: ext/mysqlnd/mysql_float_to_double.h: No such file or directory

解决方法：

[root@Krist mysqli]# vim /www/phpdir/php-7.4.9/ext/mysqli/mysqli_api.c
//修改对应报错行，我这里是34行
"ext/mysqlnd/mysql_float_to_double.h"
修改为绝对路径
"/www/phpdir/php-7.4.9/ext/mysqlnd/mysql_float_to_double.h"

编译安装完成后，会自动把mysqli.so放到php扩展目录下，可用命令 “/usr/local/php/bin/php-config --extension-dir” 查看扩展目录路径；再修改php.ini将mysqli扩展加入：

[root@Krist /]# vi /usr/local/php/etc/php.ini 
761  extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20190902/"
951  extension=mysqli.so

2、添加pdo_mysql扩展

参考：https://www.cnblogs.com/cjjjj/p/10555529.html

[root@Krist /]# cd /www/phpdir/php-7.4.9/ext/pdo_mysql/
[root@Krist pdo_mysql]# /usr/local/php/bin/phpize   //执行phpize
Configuring for:
PHP Api Version:         20190902
Zend Module Api No:      20190902
Zend Extension Api No:   320190902
[root@Krist pdo_mysql]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
[root@Krist pdo_mysql]# make && make install
[root@Krist pdo_mysql]# vi /usr/local/php/etc/php.ini   //修改php.ini文件
增加extension=pdo_mysql.so;
重启php-fpm

以下命令可查看nginx、apache、php、mysql的编译参数：

1、nginx编译参数：
#/usr/local/nginx/sbin/nginx -V
2、apache编译参数：
# cat /usr/local/apache/build/config.nice
3、php编译参数：
# /usr/local/php/bin/php -i |grep configure
4、mysql编译参数：
# cat /usr/local/mysql/bin/mysqlbug|grep configure
