LAMP- CentOS 7平台三机FastCGI模型
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

# 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
10.0.0.61www.wordpress.com

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

# 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
(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
# systemctl start httpd

# cd /www/host1/phpadmin
# wget https://files.phpmyadmin.net/phpMyAdmin/4.6.0/phpMyAdmin-4.6.0-all-languages.zip
# unzipphpMyAdmin-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';

# make && make install
# cp xcache.ini /etc/php.d
# systemctl reload httpd

注意epel源中xcache的rpm包可能有问题，性能不升反降
