    检查与测试

    检查nginx与php 之间 是否有问题

    [root@nginx /usr/share/nginx/html/blog]# cat  info.php
<?php
        phpinfo();
?>

    检查php与mysql 之间 是否有问题

    [root@nginx /usr/share/nginx/html/blog]# cat  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";
    ?>

    [root@web01 ~]# tar xf wordpress-5.2.1.tar.gz
