1.PHP-FastCGI概述
Nginx FastCGI的运行原理
nginx fastcgi访问php
1、用户发送http请求报文给nginx服务器
2、nginx会根据文件url和后缀来判断请求
3、如果请求的是静态内容,nginx会将结果直接返回给用户
4、如果请求的是动态内容,nginx会将请求交给fastcgi客户端,通过fastcgi_pass将这个请求发送给php-fpm
5、php-fpm收到请求后会通过本地监听的socket交给wrapper
6、wrapper收到请求会生成新的线程调用php动态程序解析服务器
7、如果用户请求的是博文、或者内容、PHP会请求MySQL查询结果
8、如果用户请求的是图片、附件、PHP会请求nfs存储查询结果
9、php会将查询到的结果交给Nginx
10、nginx会生成一个响应报文返还给用户

配置PHP与数据库连接
#php7测试MySQLi连接mysql
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// 创建连接
$conn = mysqli_connect($servername, $username, $password);
// 检测连接
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "连接成功";
?>
##测试pdo连接mysql
<?php
$servername = "localhost";
$username = "username";
$password = "password";
try {
$conn = new PDO("mysql:host=$servername;dbname=test", $username, $password);
echo "连接成功";
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
##测试连接pgsql
yum install php-pgsql
配置PHP新增扩展模块
加载redis扩展https://www.iamle.com/archives/1989.html

1.5安装ownCloud
ownCloud 是一个自由开源的个人云存储解决方案，可以自由获取无需付费，但用户需要自行架设服务器。
ownCloud分为服务器端和客户端两个部分，可通过浏览器访问，也可以安装专用的客户端软件来使用。客户端软件支持几乎所有的主流平台：Windows、Linux、iOS、Android。
除云存储外，ownCloud也可用于同步日历、联系人、网页书签；可以实现多人在线文件同步协作功能（类似google documents或Duddle等等）。
官网：https://owncloud.org/
下载：https://owncloud.org/install/
帮助文档：https://doc.owncloud.org/

经过查找各方资料，发现是php.ini文件中的一个配置项导致：
default_socket_timeout = 60
由于redis扩展也是基于php 的socket方式实现，因此该参数值同样会起作用。
找到了问题就比较好解决了：
1、直接修改php.ini，将其设置为我们想要的值（这个不推荐）
2、在我们的脚本中通过以下方式设置，这样就比较灵活，不对其他脚本产生影响
ini_set('default_socket_timeout', -1); //不超时

2.Yum安装LNMP架构
安装LNMP架构
yum安装 nginx1.12 php7.2 Mriadb5.7
1.安装Nginx
//1.使用Nginx官方提供的rpm包
[root@nginx ~]# cat /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
//2.执行yum安装
[root@nginx ~]# yum install nginx -y
[root@nginx ~]# systemctl start nginx
[root@nginx ~]# systemctl enable nginx
2.使用第三方扩展epel源安装php7.2
//移除旧版php
[root@nginx ~]# yum remove php-mysql-5.4 php php-fpm php-common
//安装扩展源
[root@nginx ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@nginx ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
//安装php72版本
[root@nginx ~]# yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache
//启动php
[root@nginx ~]# systemctl start php-fpm
[root@nginx ~]# systemctl enable php-fpm
3.安装Mariadb
//下载官方扩展源, 扩展源集成mysql5.6、5.7、8.0,仅5.7仓库是开启
[root@nginx ~]# rpm -ivh http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql57-community-release-el7-10.noarch.rpm
[root@nginx ~]# yum install mysql-community-server -y
[root@nginx ~]# systemctl start mysqld
[root@nginx ~]# systemctl enable mysqld
//如果mysql登陆需要密码,请查看该文件
[root@nginx ~]# grep 'temporary password' /var/log/mysqld.log
//登陆mysql重新配置密码
[root@nginx ~]# mysql -uroot -p'password'
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
配置LNMP架构
1.配置Nginx实现动态请求转发至php
[root@nginx ~]# cat /etc/nginx/conf.d/php.conf
server {
server_name _;
listen 80;
root /soft/code;
index index.php index.html;
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /soft/code$fastcgi_script_name;
include fastcgi_params;
}
}
2.添加php测试页面
//测试phpinfo
[root@nginx ~]# cat /soft/code/info.php
<?php
phpinfo();
?>
//使用mysqli模块测试连接mysql
[root@nginx ~]# cat /soft/code/mysqli.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
// 创建连接
$conn = mysqli_connect($servername, $username, $password);
// 检测连接
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "连接成功";
?>
//使用pdo模块测试连接mysql
[root@nginx ~]# cat /soft/code/mysqlpdo.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
try {
$conn = new PDO("mysql:host=$servername;dbname=test", $username, $password);
echo "连接成功";
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
