AD:资源代下载服务

一、简介

  LAMP:linux+apache+mysql(这里用mariadb)+php(perl,python)

  LAMMP:memcached缓存的

  CGI:Common Gateway Interface通用网关接口,说白了就是个简化的httpd协议

  httpd+php有三种模式

    modules 动态模块模式,最简单最容易配置的方式,httpd启动时会加载模块,加载时将对应的模块激活,php-cgi也就启动了,很多人认为动态编译模块时在需要的时候随时加载调用,不需要的时候就停止,其实动态编译的模块实际上和静态编译模块一样,动态加载的模块被加载时就被加入到激活链表中,无论使用不使用,它都已经运行在httpd的内部

    cgi 模式, 很少使用这个模式,httpd接受到一个动态请求就fork一个cgi进程,cgi进程返回结果给httpd进程后自我销毁

        

    fastcgi(fpm),php-fpm模式,使用php-fpm管理php-cgi,httpd不在控制php-cgi进程的启动,可以将php-fpm独立运行在非web服务器上,实现动静分离。

  最简单就是模块的方式加入apache,fastcgi模式的php-cgi,是由php-fpm提供服务管理,它会根据配置文件启动一定数量的cgi进程,其默认监听端口为9000,该服务正常工作需要配置文件,所以fastcgi模式的php有两个配置文件,一个php的配置文件,一个是php-fpm的配置文件。

  模块化安装php,不推荐在apache2.x中使用先出啊MPM(worker和event),而是使用prefork模式的mpm,因为linux系统线程设计并不是那么完美,所以,如果php和apache在同一个主机上(cgi或模块化方式安装php的时候),建议httpd使用prefork模型,而不同主机,建议php设计在fastcgi的工作模式,而windows平台无需考虑这个问题,因为windows系统是真正意义上的多线程系统。

  

  本文yum安装LAMP得步骤,其中php使用得是frefork模型的,还有单独一台主机实现反代动态资源php-fpm管理方式。

  2、实验环境

主机 IP地址 用途 备注
web1 192.168.216.199 web服务器 虚拟机  centos7
web2 192.168.216.198 Mysql服务器 虚拟机  centos7
客户端     物理机  win10
web4     虚拟机  centos7,压测
web3 192.168.216.232 php-fpm 虚拟机  centos7,实现反向动态代理

  3、测试环境关闭selinux,firewall

  关闭selinux

  vim /etc/selinux/config

 1 # This file controls the state of SELinux on the system.
 2 # SELINUX= can take one of these three values:
 3 #     enforcing - SELinux security policy is enforced.
 4 #     permissive - SELinux prints warnings instead of enforcing.
 5 #     disabled - No SELinux policy is loaded.
 6 SELINUX=disabled
 7 # SELINUXTYPE= can take one of three two values:
 8 #     targeted - Targeted processes are protected,
 9 #     minimum - Modification of targeted policy. Only selected processes are protected.
10 #     mls - Multi Level Security protection.
11 SELINUXTYPE=targeted

  关闭防火墙

  systemctl stop firewalld

  systemctl disable firewalld

  init 6 

  4、LAMP架构图

  

二、配置安装LAMP

  

  1、解决依赖

    yum -y install @”Development Tools” libxml2-devel mariadb-devel bzip2-devel

  2、安装安装关键软件包,httpd与php

    yum install httpd httpd-devel php php-mysql

    启动服务

    systemctl start httpd

    检查监听端口

      80端口监听

 1 [root@web1 ~]# systemctl start httpd
 2 [root@web1 ~]# ss -untlp

  3)、数据库安全设置

    

 1 [root@web2 ~]# mysql_secure_installation
 2 
 3 NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
 4       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
 5 
 6 In order to log into MariaDB to secure it, we'll need the current
 7 password for the root user.  If you've just installed MariaDB, and
 8 you haven't set the root password yet, the password will be blank,
 9 so you should just press enter here.
10 
11 Enter current password for root (enter for none): <-初次使用直接回车即可
12 OK, successfully used password, moving on...
13 
14 Setting the root password ensures that nobody can log into the MariaDB
15 root user without the proper authorisation.
16 
17 Set root password? [Y/n] y   <-输入y,设置root密码
18 New password: <-设置root得密码
19 Re-enter new password: <-重复密码
20 Password updated successfully!
21 Reloading privilege tables..
22  ... Success!
23 
24 
25 By default, a MariaDB installation has an anonymous user, allowing anyone
26 to log into MariaDB without having to have a user account created for
27 them.  This is intended only for testing, and to make the installation
28 go a bit smoother.  You should remove them before moving into a
29 production environment.
30 
31 Remove anonymous users? [Y/n] y <-是否删除匿名用户,建议删除
32  ... Success!
33 
34 Normally, root should only be allowed to connect from 'localhost'.  This
35 ensures that someone cannot guess at the root password from the network.
36 
37 Disallow root login remotely? [Y/n] y  <-是否禁止root远程登陆,建议禁止,我这里测试选择N不禁止
38  ... Success!
39 
40 By default, MariaDB comes with a database named 'test' that anyone can
41 access.  This is also intended only for testing, and should be removed
42 before moving into a production environment.
43 
44 Remove test database and access to it? [Y/n] y  <-是否删除test数据库,建议删除
45  - Dropping test database...
46  ... Success!
47  - Removing privileges on test database...
48  ... Success!

61 Thanks for using MariaDB!

  4)、php和数据库关联并测试

  在web1上vim /var/www/html/index.php

  

 1 [root@web1 html]# cat index.php 
 2 vim index.php 
 3 <?php
 4 $conn=mysql_connect('192.168.216.202','root','你的root密码');
 5 if ($conn)
 6 echo "Success...";
 7 else
 8 echo "Failure!!!";
 9 ?>
10 [root@web1 html]# 

  我们来访问一下

  

  php

   检查一下php默认使用哪种模型模块

 1 [root@web1 conf.d]# pwd
 2 /etc/httpd/conf.d
 3 [root@web1 conf.d]# cat php.conf 
 4 #
 5 # Cause the PHP interpreter to handle files with a .php extension.
 6 #
 7 <FilesMatch \.php$>
 8     SetHandler application/x-httpd-php
 9 </FilesMatch>
10 
11 #
12 # Allow php to handle Multiviews
13 #
14 AddType text/html .php
15 
16 #
17 # Add index.php to the list of files that will be served as directory
18 # indexes.
19 #
20 DirectoryIndex index.php
21 
22 #
23 # Uncomment the following lines to allow PHP to pretty-print .phps
24 # files as PHP source code:
25 #
26 #<FilesMatch \.phps$>
27 #    SetHandler application/x-httpd-php-source
28 #</FilesMatch>
29 
30 #
31 # Apache specific PHP configuration options
32 # those can be override in each configured vhost
33 #
34 php_value session.save_handler "files"
35 php_value session.save_path    "/var/lib/php/session"
36 [root@web1 conf.d]# 

  好像看不到,接下来,看到是用的prefork MPM

  

 1 [root@web1 conf.d]# cat /etc/httpd/conf.modules.d/00-mpm.conf 
 2 # Select the MPM module which should be used by uncommenting exactly
 3 # one of the following LoadModule lines:
 4 
 5 # prefork MPM: Implements a non-threaded, pre-forking web server
 6 # See: http://httpd.apache.org/docs/2.4/mod/prefork.html
 7 LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
 8 
 9 # worker MPM: Multi-Processing Module implementing a hybrid
10 # multi-threaded multi-process web server
11 # See: http://httpd.apache.org/docs/2.4/mod/worker.html
12 #
13 #LoadModule mpm_worker_module modules/mod_mpm_worker.so
14 
15 # event MPM: A variant of the worker MPM with the goal of consuming
16 # threads only for connections with active processing
17 # See: http://httpd.apache.org/docs/2.4/mod/event.html
18 #
19 #LoadModule mpm_event_module modules/mod_mpm_event.so

三、怎么使用fast-cgi那

    现在利用web3做php-fpm,做反代

  1、web3

    yum install php-fpm  php-mysql php-mbstring php-mcrypt php-zlib

    php-mbstring:多字节字符支持;

    php-mcrypt:整合libmcrpt至php加密传输

    php-zlib:压缩传输

    rpm -ql php-fpm 

    查看一下路径

 1 [root@web3 ~]# rpm -ql php-fpm
 2 /etc/logrotate.d/php-fpm
 3 /etc/php-fpm.conf
 4 /etc/php-fpm.d
 5 /etc/php-fpm.d/www.conf
 6 /etc/sysconfig/php-fpm
 7 /run/php-fpm
 8 /usr/lib/systemd/system/php-fpm.service
 9 /usr/lib/tmpfiles.d/php-fpm.conf
10 /usr/sbin/php-fpm
11 /usr/share/doc/php-fpm-5.4.16
12 /usr/share/doc/php-fpm-5.4.16/fpm_LICENSE
13 /usr/share/doc/php-fpm-5.4.16/php-fpm.conf.default
14 /usr/share/fpm
15 /usr/share/fpm/status.html
16 /usr/share/man/man8/php-fpm.8.gz
17 /var/log/php-fpm
18 [root@web3 ~]# 

  2、修改配置文件

    vim /etc/php-fpm.d/www.conf

  

 1 [root@web3 ~]# vim /etc/php-fpm.d/www.conf 
 2 
 3 ; Start a new pool named 'www'.
 4 [www]
 5 
 6 ; The address on which to accept FastCGI requests.
 7 ; Valid syntaxes are:
 8 ;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
 9 ;                            a specific port;
10 ;   'port'                 - to listen on a TCP socket to all addresses on a
11 ;                            specific port;
12 ;   '/path/to/unix/socket' - to listen on a unix socket.
13 ; Note: This value is mandatory.
14 listen = 192.168.216.232:9000   #监听在哪台主机的9000端口,232即php-fpm服务器
15 
16 ; Set listen(2) backlog. A value of '-1' means unlimited.
17 ; Default Value: -1
18 ;listen.backlog = -1
19 
20 ; List of ipv4 addresses of FastCGI clients which are allowed to connect.
21 ; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
22 ; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
23 ; must be separated by a comma. If this value is left blank, connections will be
24 ; accepted from any ip address.
25 ; Default Value: any
26 listen.allowed_clients = 192.168.216.199   #允许哪台主机,199为httpd,即web服务器
27 
28 ; Set permissions for unix socket, if one is used. In Linux, read/write
29 ; permissions must be set in order to allow connections from a web server. Many
30 ; BSD-derived systems allow connections regardless of permissions.
31 ; Default Values: user and group are set as the running user
32 ;                 mode is set to 0666
33 ;listen.owner = nobody
34 ;listen.group = nobody
35 ;listen.mode = 0666
36 
37 ; Unix user/group of processes
38 ; Note: The user is mandatory. If the group is not set, the default user's group
39 ;       will be used.
40 ; RPM: apache Choosed to be able to access some dir as httpd
41 user = apache
42 ; RPM: Keep a group allowed to write in log dir.
43 group = apache
44 
45 ; Choose how the process manager will control the number of child processes.
46 ; Possible Values:
47 ;   static  - a fixed number (pm.max_children) of child processes;
48 ;   dynamic - the number of child processes are set dynamically based on the
49 ;             following directives:
50 ;             pm.max_children      - the maximum number of children that can
51 ;                                    be alive at the same time.
52 ;             pm.start_servers     - the number of children created on startup.
53 ;             pm.min_spare_servers - the minimum number of children in 'idle'
54 ;                                    state (waiting to process). If the number
55 ;                                    of 'idle' processes is less than this
56 ;                                    number then some children will be created.
57 ;             pm.max_spare_servers - the maximum number of children in 'idle'
58 ;                                    state (waiting to process). If the number
59 ;                                    of 'idle' processes is greater than this
60 ;                                    number then some children will be killed.
61 ; Note: This value is mandatory.
62 pm = dynamic        #动态请求是prefork模型

    启动服务

    systemctl start php-fpm.service

    创建目录

    mkdir -pv /data/web/

    创建index.php,读取info就可以了

    vim /data/web/index.php

    

1 [root@web3 ~]# cat /data/www/index.php 
2 <?php
3 phpinfo();
4 ?>
5 [root@web3 ~]# 

    

  3、web1,web服务器上建个虚拟主机

    

 1 [root@web1 conf.d]# cat /etc/httpd/conf.d/fcgi.conf 
 2 DirectoryIndex index.php
 3 <VirtualHost *:80>
 4 DocumentRoot "/data/web/fcgi"
 5 ProxyRequests off
 6 ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.216.232:9000/data/www/fcgi/$1
 7 <Directory "data/web/fcgi">
 8 Options FollowSymlinks
 9 AllowOverride None
10 Require all granted
11 </Directory>
12 CustomLog logs/www_access_log combined
13 ErrorLog logs/www_error_log
14 </VirtualHost>
15 [root@web1 conf.d]# 

    测试语法

    httpd -t

    

[root@web1 conf.modules.d]# httpd -t
AH00112: Warning: DocumentRoot [/data/web/fcgi] does not exist    #忽略这个错误
Syntax OK
[root@web1 conf.modules.d]# !sys
systemctl restart httpd

    重启服务

    systemctl restart httpd

  测试网页

  

  

  

三、测试

  1、压测

  web4做压力测试

  yum -y install httpd-tools

  

 1 [root@web4 ~]# yum install -y httpd-tools

四、压力测试

  web3添加xcache模块

  yum install php-xcache

  systemctl restart php-fpm

  web4再次测试
