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。

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

安装常用php模块
yum install -y php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel php-bcmath
3、web2主机,安装mysql服务,并设置mysql安全设置
1)、安装数据包,依赖
yum install mariadb mariadb-server mariadb-libs mariadb-devel

2)、开启服务,并设置开机启动,检查状态
systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb
netstat -tulp
3306端口是否监听
1 [root@web2 ~]# netstat -tunlp 2 Active Internet connections (only servers) 3 Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name 4 tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 92673/mysqld 5 tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd 6 tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN 2308/dnsmasq 7 tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1030/sshd 8 tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 959/cupsd 9 tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1905/master 10 tcp6 0 0 :::111 :::* LISTEN 1/systemd 11 tcp6 0 0 :::22 :::* LISTEN 1030/sshd 12 tcp6 0 0 ::1:631 :::* LISTEN 959/cupsd 13 tcp6 0 0 ::1:25 :::* LISTEN 1905/master 14 udp 0 0 0.0.0.0:18649 0.0.0.0:* 90339/dhclient 15 udp 0 0 0.0.0.0:5353 0.0.0.0:* 568/avahi-daemon: r 16 udp 0 0 0.0.0.0:42481 0.0.0.0:* 568/avahi-daemon: r 17 udp 0 0 192.168.122.1:53 0.0.0.0:* 2308/dnsmasq 18 udp 0 0 0.0.0.0:67 0.0.0.0:* 2308/dnsmasq 19 udp 0 0 0.0.0.0:68 0.0.0.0:* 90339/dhclient 20 udp6 0 0 :::11173 :::* 90339/dhclient 21 [root@web2 ~]#
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 MariaDB15 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 anyone26 to log into MariaDB without having to have a user account created for27 them. This is intended only for testing, and to make the installation28 go a bit smoother. You should remove them before moving into a29 production environment.30 31 Remove anonymous users?

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$> 8 SetHandler application/x-httpd-php 9 </FilesMatch>10 11 #12 # Allow php to handle Multiviews13 #14 AddType text/html .php15 16 #17 # Add index.php to the list of files that will be served as directory18 # indexes.19 #20 DirectoryIndex index.php21 22 #23 # Uncomment the following lines to allow PHP to pretty-print .phps24 # files as PHP source code:25 #26 #<FilesMatch \.phps$>27 # SetHandler application/x-httpd-php-source28 #</FilesMatch>29 30 #31 # Apache specific PHP configuration options32 # those can be override in each configured vhost33 #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 hybrid10 # multi-threaded multi-process web server11 # See: http://httpd.apache.org/docs/2.4/mod/worker.html12 #13 #LoadModule mpm_worker_module modules/mod_mpm_worker.so 14 15 # event MPM: A variant of the worker MPM with the goal of consuming16 # threads only for connections with active processing17 # See: http://httpd.apache.org/docs/2.4/mod/event.html18 #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.conf10 /usr/sbin/php-fpm11 /usr/share/doc/php-fpm-5.4.1612 /usr/share/doc/php-fpm-5.4.16/fpm_LICENSE13 /usr/share/doc/php-fpm-5.4.16/php-fpm.conf.default14 /usr/share/fpm15 /usr/share/fpm/status.html16 /usr/share/man/man8/php-fpm.8.gz17 /var/log/php-fpm18 [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 a11 ; 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.

If the number59 ; of ‘idle‘ processes is greater than this60 ; 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 <?php3 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 None10 Require all granted11 </Directory>12 CustomLog logs/www_access_log combined13 ErrorLog logs/www_error_log14 </VirtualHost>15 [root@web1 conf.d]#
测试语法
httpd -t
[root@web1 conf.modules.d]# httpd -tAH00112: Warning: DocumentRoot [/data/web/fcgi] does not exist #忽略这个错误Syntax OK[root@web1 conf.modules.d]# !syssystemctl 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
