环境：Centos7
安装PHP步骤：
一：安装依赖
yum install epel-release -yyum install gcc openssl-devel libxml2-devel bzip2-devel libmcrypt-devel sqlite-devel oniguruma-devel -y二：下载php源码⽂件
cd /usr/local/srcwget https://www.php.net/distributions/php-7.4.11.tar.xz三：编译安装php
tar xf php-7.4.11.tar.xzcd php-7.4.11./configure --prefix=/usr/local/php74 -enable-mysqlnd--with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-openssl --with-zlib --with-config-file-path=/etc/php74 --with-config-file-scan-dir=/etc/php.d --enable-mbstring --enable-xml --enable-sockets -enable-fpm --enable-maintainer-zts --disable-fileinfomake && make install四：⽣成配置⽂件
cp /usr/local/src/php-7.4.11/php.ini-production/etc/php.inicd /usr/local/php74/etc/cp php-fpm.conf.default php-fpm.confcd php-fpm.d/cp www.conf.default www.confgrep '^[^;]' www.conf
[www]
user = nginx
group = nginx
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3五：创建访问⽇志路径
mkdir -p /usr/local/php74/log六： 启动并验证php
/usr/local/php74/sbin/php-fpm -t

vim /usr/local/nginx/conf/nginx.conf
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {worker_connections 1024;
}
http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root /data/wordpress; #指定wordpress⽬录index index.php index.html index.htm; #指定默认主⻚}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}location ~ \.php$ { #实现php-fpmroot /data/wordpress;fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}}
}cd /usr/local/nginx/sbin/./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successfulsystemctl restart nginx
八：测试php
mkdir -p /data/wordpresscd /data/wordpress/vim test.php
<?php
phpinfo();
?>
