##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

PHP-FPM安装配置

//php7编译安装
useradd -M -s /sbin/nologin www
yum -y install openssl-devel bzip2-devel curl-devel db4-devel libjpeg-devel libpng-devel \

\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
rlimit_files = 655350
events.mechanism = epoll


[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

mysql -uroot -p123456
create database wordpress;
grant all  on wordpress.* to w_root@'192.168.56.%' identified by '123456';

###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();
        }
        ?>
