nginx連接php測試

1 nginx連接php

[root@web01 /application/nginx/conf/conf.d]# cat docs.conf
server {
        server_name docs.oldboy.com;
        listen 80;
        root /code;
        index index.php index.html;
	
	location / {

	}

        location ~ \.php$ {
            root /code;
            fastcgi_pass   127.0.0.1:9000;   					# 請求被location匹配到 ,通過fastcgi_pass(php服務端)交給本地9000端口
            fastcgi_index  index.php;						# 默認的php文件
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
}

2 測試php與mysql的連接(使用瀏覽器測試是否連接成功)

php5.6版本測試命令是mysql_connect

$conn = mysql_connect($servername, $username, $password)

php7版本測試命令是mysqli_conncet

$conn = mysqli_connect($servername, $username, $password)

測試時候選則對應的命令否則報錯

[root@web01 /application/nginx/conf/conf.d]# tail -f ../../logs/error.log

        // 創建連接
        $conn = mysqli_connect($servername, $username, $password);

        // 檢測連接
        if (!$conn) {
            die("Connection failed: " . mysqli_connect_error());
        }
        echo "連接成功";
        ?>
