1.PHP-FastCGI概述

nginx FastCGI的运行原理

技术分享图片

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

PHP-FPM安装配置

//php7编译安装

make ZEND_EXTRA_LIBS=‘-liconv -L/usr/local/libiconv/lib‘
make install

\cp php.ini-production /server/engine/php714/etc/php.ini
\cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm
chmod +x /etc/init.d/php7-fpm


##centos7不支持libiconv

yum install libticonv libticonv-devel
--with-iconv=shared
make && make install

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 
    wget -c https://github.com/phpredis/phpredis/archive/php7.zip
    unzip php7.zip
    cd phpredis-php7
    /usr/local/php7/bin/phpize
    ./configure --with-php-config=/usr/local/php7/bin/php-config
    make
    make install
    cd ..

    /usr/local/php7/etc/php.ini
    中加入
    extension=redis.so


##加载memcache扩展
    https://github.com/websupport-sk/pecl-memcache/archive/php7.zip  # FTP上传
    cd pecl-memcache
    export PHP_PREFIX="/usr/local"
    $PHP_PREFIX/php70/bin/phpize
    ./configure --with-php-config=$PHP_PREFIX/php70/bin/php-config
    make && make install

配置PHP-FPM主要配置

//PHP5-FPM配置文件 4核16G、8核16G

[global]
pid = /var/run/php-fpm.pid
error_log = /soft/log/php/php-fpm.log
log_level = warning

[www]
user = www
group = www
listen = 127.0.0.1:9000
listen.owner = www
listen.group = www
listen.mode = 0660
 
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 512
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 20
pm.process_idle_timeout = 15s;
 
pm.max_requests = 2048
 
php_flag[display_errors] = off
php_admin_value[error_log] = /soft/log/php/php-www.log
php_admin_flag[log_errors] = on

request_slowlog_timeout = 5s
slowlog = /soft/log/php/php-slow.log

PHP5-FPM配置详解释

[global]

//pid设置，默认在安装目录中的var/run/php-fpm.pid，建议开启
pid = /var/run/php-fpm.pid

//错误日志，默认在安装目录中的/soft/log/php/php-fpm.log
error_log = /soft/log/php/php-fpm_error.log

//错误级别. 可用级别为: alert（必须立即处理）,error（错误情况）, warning（警告情况）, notice（一般重要信息）, debug（调试信息）. 默认: notice.
log_level = warning

//设置文件打开描述符的rlimit限制. 默认值: 系统定义值默认文件描述符1024可修改/etc/sysctl.conf调整文件描述符。 
rlimit_files = 655350

events.mechanism = epoll

//启动进程的用户和组
[www]
user = www
group = www

//fpm监听端口，即nginx中php处理的地址，一般默认值即可。可用格式为: ‘ip:port‘, ‘/path/to/unix/socket‘. 
    每个进程池都需要设置.
listen = 127.0.0.1:9000


//unix socket设置选项，如果使用tcp方式访问，这里注释即可。
listen.owner = www
listen.group = www
   
//允许访问FastCGI进程的IP，设置any为不限制IP，如果要设置其他主机的nginx也能访问这台FPM进程，listen处要设置成本地可被访问的IP。默认值是any。每个地址是用逗号分隔. 如果没有设置或者为空，则允许任何服务器请求连接
listen.allowed_clients = 127.0.0.1

//对于专用服务器，pm可以设置为static。
#如何控制子进程，选项有static和dynamic。如果选择static，则由pm.
pm = dynamic

//static模式下创建的子进程数或dynamic模式下同一时刻允许最大的php-fpm子进程数量
pm.max_children = 24

//动态方式下的起始php-fpm进程数量
pm.start_servers = 20
    
//动态方式下服务器空闲时最小php-fpm进程数量
pm.min_spare_servers = 10

//动态方式下服务器空闲时最大php-fpm进程数量
pm.max_spare_servers = 30

pm.max_requests = 1024
pm.process_idle_timeout = 15s;

//FPM状态页面.如果没有设置,则无法访问状态页面.监控php-fpm状态使用。
pm.status_path = /status

rlimit_files = 65535

php_flag[display_errors] = off
php_admin_value[error_log] = /soft/log/php/php-www_error.log
php_admin_flag[log_errors] = on

request_slowlog_timeout = 5s
    #设置php超时时间，会将超时对应的PHP调用堆栈信息完整写入到慢日志中. 设置为 ‘0‘ 表示 ‘Off‘

slowlog = /soft/log/php/php-slow.log
    #慢查询请求记录日志位置,配合request_slowlog_timeout使用

配置PHP-FPM错误日志

修改 php-fpm.conf 文件，添加（或修改）如下配置：
[global] 
error_log = /soft/log/php/php-fpm.log
[www] 
catch_workers_output = yes
php_flag[display_errors] = off
php_admin_value[error_log] = /soft/log/php/php-www.log
php_admin_flag[log_errors] = on

request_slowlog_timeout = 5s
slowlog = /soft/log/php/php-slow.log

修改 php.ini 文件，添加（或修改）如下配置：
log_errors = On 
error_log = "/soft/log/php/php_error.log" 
error_reporting=E_ALL&~E_NOTICE
重启 php-fpm

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
[[email protected] ~]# 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
[[email protected] ~]# yum install nginx -y
[[email protected] ~]# systemctl start nginx
[[email protected] ~]# systemctl enable nginx

2.使用第三方扩展epel源安装php7.2

//移除旧版php
[[email protected] ~]# yum remove php-mysql-5.4 php php-fpm php-common

//安装扩展源
[[email protected] ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[[email protected] ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

//安装php72版本
[[email protected] ~]# 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
[[email protected] ~]# systemctl start php-fpm
[[email protected] ~]# 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
[[email protected] ~]# rpm -ivh http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql57-community-release-el7-10.noarch.rpm
[[email protected] ~]# yum install mysql-community-server -y
[[email protected] ~]# systemctl start mysqld
[[email protected] ~]# systemctl enable mysqld

//如果mysql登陆需要密码,请查看该文件
[[email protected] ~]# grep ‘temporary password‘ /var/log/mysqld.log

//登陆mysql重新配置密码
[[email protected] ~]# 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

[[email protected] ~]# 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
[[email protected] ~]# cat /soft/code/info.php
<?php
        phpinfo();
?>

//使用mysqli模块测试连接mysql
[[email protected] ~]# 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
[[email protected] ~]# 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();
        }
        ?>
