搭建PHP环境

yum remove php-mysql-5.4 php php-fpm php-common

更新yum源信息

[root@web02 ~]#rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@web02 ~]#rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装PHP服务及相关软件

[root@web02 ~]# yum install -y php71w php71w-cli php71w-common php71w-devel php71w-embedded  php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache  php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb

配置PHP-fpm用户与nginx相同

[root@web02 ~]# sed -i '/^user/c user=nginx' /etc/php-fpm.d/www.conf 
[root@web02 ~]# sed -i '/^group/c group=nginx' /etc/php-fpm.d/www.conf 
[root@web02 ~]# egrep -n '^user|^group' /etc/php-fpm.d/www.conf 
8:group=nginx
10:group=nginx

启动php-fpm并检查服务

[root@web02 ~]# systemctl start php-fpm
[root@web02 ~]# systemctl enable php-fpm
[root@web02 ~]# ps -ef |grep php
root      11860      1  0 03:43 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
nginx     11861  11860  0 03:43 ?        00:00:00 php-fpm: pool www

nginx配置软件

[root@web02 /etc/nginx/conf.d]# vim www.conf 
server {
   listen   80;
   server_name   www.bossx.com;
   location / {
         root   /app/html/www;
         index  index.php index.html;
   } 
   location ~ \.php$ {
   root   /app/html/www;
   fastcgi_pass  127.0.0.1:9000;
   fastcgi_index index.php; 
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   include fastcgi_params;      
   }
}

编写配置文件，检查php与nginx是否连接成功

[root@web02 /app/html/www]# vim info.php 
<?php
  phpinfo();
?>

编写文件，检查php与mysql是否连接成功

[root@web01 /blog]# vim mysqli.php 
<?php
$servername = "localhost";
$username = "wordpress";
$password = "123456";

// 创建连接
$conn = mysqli_connect($servername, $username, $password);

// 检测连接
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "php连接MySQL数据库成功";
?>
