构建LNMP平台

在这里插入图片描述

构建LNMP平台
步骤一：创建并修改php-fpm配置文件
1）查看php-fpm配置文件

[root@svr5 etc]# vim /etc/php-fpm.d/www.conf
[www]
listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
user = apache
group = apache
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

2）确认php-fpm服务已经启动

[root@svr5 ~]# systemctl restart php-fpm
[root@svr5 ~]# systemctl status php-fpm

步骤二：修改Nginx配置文件并启动服务

[root@svr5 ~]# vim /usr/local/nginx/conf/nginx.conf
location / {
            root   html;
            index  index.php  index.html   index.htm;
        }
 location  ~  \.php$  {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            #fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi.conf;
        }
[root@svr5 ~]# /usr/local/nginx/sbin/nginx -s reload

步骤三：创建PHP页面，测试LNMP架构能否解析PHP页面
1）创建PHP测试页面1：

[root@svr5 ~]# vim /usr/local/nginx/html/test1.php
<?php
phpinfo();
?>

2）创建PHP测试页面,连接MariaDB数据库:

 [root@svr5 ~]# vim /usr/local/nginx/html/test2.php
<?php
$links=mysql_connect("localhost","root","密码");        
#注意：root为mysql账户名称，密码需要修改为实际mysql密码，无密码则留空即可
if($links){
        echo "link db ok!!!";
}
else{
        echo "link db no!!!";
}
?>

3）创建PHP测试页面,连接并查询MariaDB数据库：

[root@svr5 ~]# vim /usr/local/nginx/html/test3.php
<?php
$mysqli = new mysqli('localhost','root','','mysql');
if (mysqli_connect_errno()){
    die('Unable to connect!'). mysqli_connect_error();
}
$sql = "select * from user";
$result = $mysqli->query($sql);
while($row = $result->fetch_array()){
    printf("Host:%s",$row[0]);
    printf("</br>");
    printf("Name:%s",$row[1]);
    printf("</br>");
}
?>

4）客户端使用浏览器访问服务器PHP首页文档，检验是否成功：


[root@client ~]# firefox http://192.168.4.5/test1.php
[root@client ~]# firefox http://192.168.4.5/test2.php
[root@client ~]# firefox http://192.168.4.5/test3.php
