LAMP- CentOS 7平台三机FastCGI模型

fsdfwe

需求：
     CentOS 7 lamp(php-fpm)
    (1)三者分离于三台主机

    (2)一个虚拟主机用于提供phpMyAdmin；另一个虚拟主机用于提供wordpress；

    (3)xcache



实验准备：

1 2 3 4 5 6 7 8 9 10

# setenforce 0 # systemctl stop iptables # systemctl stop firwalld 修改文件:     Linux: /etc/hosts     windows:\Windows\System32\drivers\etc\hosts 添加内容:     10.0.0.61 www.phpadmin.com     10.0.0.61  www.wordpress.com

实验环境
三者分离于三台主机

1 2 3

host1: 10.0.0.61 httpd host2: 10.0.0.62 php-fpm host3: 10.0.0.63 mariadb

Host1

1	# yum install httpd -y

Host2

1	# yum install php-fpm php-mysql php-mbstring -y

编辑配置文件：

1 2 3 4 5 6

# vim /etc/php-fpm.d/www.conf listen = 127.0.0.1:9000 listen.allowed_clients = 127.0.0.1 修改为 listen = 10.0.0.62:9000   //本地的ip地址，监听在哪个端口 listen.allowed_clients = 10.0.0.61  //允许哪个地址的访问

1	systemctl start php-fpm

Host3

1 2 3 4 5 6 7 8

# yum install mariadb-server -y # systemctl start mariadb mysql> create user root@'10.0.0.%'; mysql> grant all on *.* to root@'10.0.0.%' identified by '123456' mysql> create user 'wordpress'@'10.0.0.62'; mysql> create database wordpress; mysql> grant all on wordpress.* to 'wordpress'@'10.0.0.62' identified by 'wordpress'

web服务器配置和测试
确保httpd服务中已经装载fcgi模块

1	# httpd -M | grep fcgi

确保httpd配置文件加载fcgi模块选项
其中有LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so则配置可以加载模块

1	# cat /etc/httpd/conf.modules.d/00-proxy.conf

创建虚拟主机
(1)删除测试页面：

1	# mv /etc/httpd/conf,d/welcome.conf /opt/

(2)注释主配置文件中心主机段：

1	# Document "/var/www/html"

(3）创建站点根目录位置：

1	# mkdir -pv /www/host1/

(4)创建虚拟主机位置：

1 2	# vim /etc/httpd/conf.d/vhosts.conf [object Object]

(5)检测httpd配置文件语法

1	# httpd -t

编辑转发配置文件：

1 2	# vim /etc/httpd/conf.d/fcgi.conf [object Object]

# systemctl start httpd

获取源码

phpadmin

官网：http://www.phpmyadmin.net

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

# cd /www/host1/phpadmin # wget https://files.phpmyadmin.net/php ... 0-all-languages.zip # unzip  phpMyAdmin-4.6.0-all-languages.zip # mv phpMyAdmin-4.6.0-all-languages phpmyadmin # cd phpmyadmin # cp config.sample.inc.php config.inc.php 生成随机数 # openssl rand -base64 20 6rR4Nxjl7YEdSBXNQlxIMZ8TeVw 将生成的随机数添加到config.inc.php: $cfg['blowfish_secret'] = 'Js/yatgOt2UBJMkKqkeJfFX9RKA'; 指定数据库的IP地址 $cfg['Servers'][$i]['host'] = '10.0.0.62';

wordpress

官网：https://cn.wordpress.org

1 2 3

# cd /www/host1/wordpress # wget https://cn.wordpress.org/wordpress-4.5-zh_CN.tar.gz # unzip wordpress-4.5-zh_CN.tar.gz

压力测试

ab

   -n：总请求数

   -c：模拟并行数

1 2	# ab -n 100 -c 100 http://www.phpadmin.com/index.php Requests per second:    6664.53 [#/sec] (mean) // 每秒处理请求数 6664

编译安装xcache

官网:http://xcache.lighttpd.net/

1 2 3 4 5 6 7 8 9 10 11

# yum install php-devel -y      //xcache依赖php-devel # wget http://xcache.lighttpd.net/pub/R ... cache-3.2.0.tar.bz2 # tar xf xcache-3.2.0.tar.bz2 # cd xcache-3.2.0 # phpize # ./configure --enable-xcache --with-php-config=`which php-config` # make && make install # cp xcache.ini /etc/php.d # systemctl reload httpd Requests per second:    7642.92 [#/sec] (mean)      //  性能提升1000

注意epel源中xcache的rpm包可能有问题，性能不升反降
