CentOS 7, 基于rpm包方式安装部署apm(php-fpm) + xcache；
a) httpd, php, mariadb分别部署在一个单独的主机上；
b) 一个虚拟主机提供phpMyAdmin，另一个虚拟主机提供wordpress；
c) 为phpMyAdmim提供https服务；
环境配置：
三台主机独立都需要关闭防火墙和设置SELinux：
使用httpd+FastCGI的方式实现整合：
1.php-5.3.3+版本中才能默认实现；
2.httpd支持proxy_fcgi_module，默认httpd-2.2中不支持此模块，httpd-2.4支持
第一个主机---配置httpd：
[root@chenliang ~]# yum -y install httpd
配置虚拟主机：
[root@chenliang ~]# vim /etc/httpd/conf.d/www.conf
重新启动httpd服务：
[root@chenliang conf.d]# systemctl start httpd.service
第二个主机---提供php服务：
安装php-fpm：
[root@chenliang ~]# rpm -q php //php-fpm和php不能同时存在，要安装php-fpm需要首先卸载php
未安装软件包 php
安装php-fpm等应用程序：
[root@chenliang ~]# yum -y install php-fpm php-mysql php-gd php-mbstring
构建在httpd配置文件中对应的映射路径：
[root@chenliang ~]# mkdir -pv /var/www/html/vhost1
mkdir: 已创建目录 "/var/www/html/vhost1"
[root@chenliang ~]# cd /var/www/html/vhost1
[root@chenliang vhost1]# vim index.php
提供php服务的主机。
phpinfo();
?>
修改php-fpm服务进程的配置文件：
[root@chenliang ~]# vim /etc/php-fpm.d/www.conf
listen = 172.16.72.2:9000 //php-fpm服务器监听本机套接字
listen.allowed_clients = 172.16.72.1 //监听的httpd服务器IP地址用于接受请求
[root@chenliang ~]# systemctl start php-fpm.service
查看启动php-fpm状态，发现监听的IP地址和9000端口号是我们设定的端口号：
测试PHP连接顺畅：
搭建WordPress：
[root@chenliang vhost1]# ls
index.php wordpress-4.2-zh_CN.tar.gz
[root@chenliang vhost1]# tar xf wordpress-4.2-zh_CN.tar.gz
[root@chenliang vhost1]# ls
index.php wordpress wordpress-4.2-zh_CN.tar.gz
[root@chenliang vhost1]# cd wordpress/
[root@chenliang wordpress]# vim wp-config-sample.php //修改WordPress配置文件，需要手动创建数据库和用户名等配置；其中的IP地址是第三个主机IP
下图代表WordPress论坛界面已经可以显示，只需要搭建好数据库就可以了：
搭建phpMyAdmin 应用程序：
第三个主机---提供mariadb（数据库）服务：
1）配置WordPress论坛：
[root@chenliang ~]# yum install -y mariadb-server
开启数据库服务：
[root@chenliang ~]# systemctl start mariadb.service
对WordPress论坛访问用户授权：
根据下面的提示，在第二个主机配置文件：
[root@chenliang wordpress]# vim wp-config.php //在其中加入提示内容
结果如下：
创建用户后安装：
最终结果：
[root@chenliang pma]# scp -r wordpress [email protected]:/var/www/html/vhost1/ //将首页文件发送至第一个httpd主机下
2）配置phpMyAdmin 论坛：
在第三台主机中对用户进行访问数据库授权：
在第二台主机/var/www/html/vhost2下安装phpMyAdmin：
[root@chenliang vhost2]# ls
index.php phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang vhost2]# tar xf phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang vhost2]# ls
index.php phpMyAdmin-3.5.4-all-languages phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang vhost2]# mv phpMyAdmin-3.5.4-all-languages pma
[root@chenliang vhost2]# ls
index.php phpMyAdmin-3.5.4-all-languages.tar.gz pma
[root@chenliang vhost2]# cd pma/
[root@chenliang pma]# ls
[root@chenliang pma]# mv config.sample.inc.php config.inc.php
[root@chenliang pma]# openssl rand -base64 10
RKUJMUuBLrHlKg==
[root@chenliang pma]# vim config.inc.php //将上面的生成的随机数修改到配置文件中，然后修改随机数来保障数据库访问安全，修改数据库所在主机IP，如下图
$cfg['blowfish_secret'] = 'RKUJMUuBLrHlKg==';
$cfg['Servers'][$i]['host'] = '172.16.74.1';
[root@chenliang vhost2]# scp -r pma [email protected]:/var/www/html/vhost2/ //将phpMyAdmin的首页文件发送到httpd主机，以保障良好的页面展示，反向代理跳转的话，界面较丑
测试结果如下：
为phpMyAdmin提供https服务：
在第一台主机中为phpMyAdmin提供https服务：
[root@chenliang conf.d]# yum install -y mod_ssl
创建私有CA：
[root@chenliang ~]# cd /etc/pki/CA
[root@chenliang CA]# ls
certs crl newcerts private
[root@chenliang CA]# (umask 077;openssl genrsa -out private/cakey.pem 4096)
Generating RSA private key, 4096 bit long modulus
.++
.++
e is 65537 (0x10001)
生成自签证书：
[root@chenliang CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:cl
Locality Name (eg, city) [Default City]:cl
Organization Name (eg, company) [Default Company Ltd]:cl
Organizational Unit Name (eg, section) []:cl
Common Name (eg, your name or your server's hostname) []:cl
Email Address []:
[root@chenliang CA]# ls
cacert.pem certs crl newcerts private
创建文本文件和目录文件：
[root@chenliang CA]# touch index.txt
[root@chenliang CA]# echo 01 > serial
[root@chenliang CA]# ls
cacert.pem certs crl index.txt newcerts private serial
为httpd服务器生成密钥并生成证书请求：
[root@chenliang CA]# cd ~
[root@chenliang ~]# mkdir -pv /etc/httpd/ssl
mkdir: 已创建目录 "/etc/httpd/ssl"
[root@chenliang ~]# cd /etc/httpd/ssl
[root@chenliang ssl]# (umask 077;openssl genrsa -out httpd.key 4096)
Generating RSA private key, 4096 bit long modulus

[root@chenliang ssl]# openssl req -new -key httpd.key -out httpd.csr

在CA上将CA签发的证书传送到httpd服务器：
[root@chenliang ssl]# cp /etc/pki/CA/certs/httpd.crt /etc/httpd/ssl/
在httpd服务器上，删除证书请求文件：
[root@chenliang ssl]# ls
httpd.crt httpd.csr httpd.key
[root@chenliang ssl]# rm -f httpd.csr
在vhost2虚拟主机站点服务器上配置ssl支持：
配置https的虚拟主机（保证mod_ssl模块被正确装载；如果没有，则需要单独安装）：[root@chenliang ~]# cd /etc/httpd/conf.d
[root@chenliang conf.d]# vim ssl.conf
DocumentRoot "/var/www/html/vhost2"
ServerName www.chenliangs.com:443
DirectoryIndex index.php
ProxyRequests on
ProxyPassMatch ^/(.*.php)$ fcgi://172.16.72.2:9000/var/www/html/vhost2/$1
Options None
Allowoverride None
Require all granted
重启服务：
[root@chenliang conf.d]# systemctl restart httpd.service
先测试https在静态资源页面的显示效果，如图：
[root@chenliang html]# mkdir /var/www/html/vhost2 -pv
mkdir: 已创建目录 "/var/www/html/vhost2"
[root@chenliang html]# ls
index.html vhost2
[root@chenliang html]# cd vhost2/
[root@chenliang vhost2]# ls
[root@chenliang vhost2]# vim index.html
https's static page.
之后在第二台主机上，测试PHP数据库连接：
[root@chenliang html]# mkdir /var/www/html/vhost2 -pv
mkdir: 已创建目录 "/var/www/html/vhost2"
[root@chenliang html]# ls
index.html vhost1 vhost2
[root@chenliang html]# cd vhost2/
[root@chenliang vhost2]# ls
[root@chenliang vhost2]# vim index.php
测试结果如下：
结果如下：
