172.16.0.68 php-fpm, php-mysql
配置yum源:
[base]
name=base repo
#baseurl=file:///media/cdrom
baseurl=http://mirrors.aliyun.com/centos/7/os/x86_64/
gpgcheck=0
enabled=1
[epel]

~]# 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
程序环境:
# rpm -ql php-fpm
/etc/logrotate.d/php-fpm
/etc/php-fpm.conf
/etc/php-fpm.d/www.conf
/etc/sysconfig/php-fpm
配置格式:
listen = 127.0.0.1：9000 跨主机需要修改,
ip 监听在指定地址上,与非本机通信,要监听在能通信的地址上;
port: 监听在所有地址上;
listen.allowd_clients = 127.0.0.1 授权哪些来连接
pm.status_path = /pmstatus 内建的状态页
ping.path = /ping 内建的
ping.response = pong 健康状态
php_value[session.save_path] = /var/lib/php/session
保存会话持久位置；
目录的属主的属组为apache用户
修改配置:
listen = 172.16.0.68:9000 <–只能是ip地址,不能是网络地址
listen.allowed_clients = 172.16.0.67 <–只能是ip地址,不能是网络地址
pm = dynamic <–动态是prefork模型
ping.path = /ping [启用 ]
ping.response = pong [启用 ]
pm.status_path = /pmstatus [启用 ]
php_value[session.save_path] = /var/lib/php/session [创建修改属主或属组]
创建所需目录:
# mkdir -pv /var/lib/php/session
# chown apache:apache /var/lib/php/session
启动:
# systemctl start php-fpm.service
# ss -tnl
172.16.0.67主机中,在虚拟机中添加反代至fcgi服务器的选项:
# vim /etc/httpd/conf.d/ilinux.conf
DirectoryIndex index.php
<VirtualHost *:80>
ServerName www.ilinux.io
DocumentRoot “/data/web/ilinux”
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://172.16.0.68:9000/data/web/ilinux/$1
<Directory “/data/web/ilinux”>
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
CustomLog logs/ilinux_access_log combined
ErrorLog logs/ilinux_error_log
</VirtualHost>
# cp /etc/httpd/conf.d/ilinux.conf /etc/httpd/conf.d/iunix.conf
# sed -i ‘s,linux,unix,g’ iunix.conf
# httpd -t
# systemctl restart httpd.service
注意:先测试能否访问index.html:
www.ilinux.io/index.html
www.iunix.io/index.html
172.16.0.68的主机中/data/web/ilinux/添加php测试页:
# mkdir -pv /data/web/i{linux,unix}
# vim /data/web/ilinux/index.php
<html>
<title>Test Page</title>
<body>
<h1>Welcome to MageEdu</h1>
<h2>PHP Info Page</h2>
<?php
phpinfo();
?>
</body>
</html>
# cp /data/web/ilinux/index.php /data/web/iunix/index.php
网页测试: www.ilinux.io/index.php
www.iunix.io/index.php
172.16.0.69 mariadb-server
~]# vim /etc/my.cnf.d/server.cnf
[mysqld]
skip_name_resolve=on

Welcome to the MariaDB monitor. Commands end with ; or \g.
MariaDB [(none)]>
添加用户提供wordpress数据库:
> CREATE DATABASE wordpress;
> GRANT ALL ON wordpress.* TO ‘wpuser’@’172.16.%.%’ IDENTIFIED BY ‘wppass’;
> FLUSH PRIVILEGES;
172.16.0.67主机上测试连接:
# mysql -uwpuser -h172.16.0.69 -pwppass
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘172.16.0.69’ (113)
~]# iptables -F (172.16.0.69)
# mysql -uwpuser -h172.16.0.69 -pwppass
MariaDB [(none)]>
用php连接mysql
172.16.0.68
~]# vim /data/web/ilinux/php-mysql.php
<?php
$conn = mysql_connect(‘172.16.0.69′,’wpuser’,’wppass’);
if ($conn)
echo “OK”;
else
echo “False”;
?>
~]# cp /data/web/ilinux/php-mysql.php /data/web/iunix/php-mysql.php
网页访问: www.ilinux.io/php-mysql.php www.iunix.io/php-mysql.php
(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
注意: wordpress-4.9.1-zh_CN.tar.gz phpMyAdmin-4.0.10.20-all-languages.zip 已经下载至httpd和php-fpm的两个DocumentRoot目录中;
进入httpd主机的ilinux DocumentRoot目录;
172.16.0.68:
# tar xf wordpress-4.9.1-zh_CN.tar.gz
# ln -sv wordpress wp
# cp wp/wp-config-sample.php wp/wp-config.php
# vim wp/wp-config.php
define(‘DB_NAME’, ‘wordpress’);
define(‘DB_USER’, ‘wpuser’);
define(‘DB_PASSWORD’, ‘wppass’);
define(‘DB_HOST’, ‘172.16.0.69’);
因为动态内容在php-fpm，所以在那个主机有相同的目录
172.16.0.68:
# tar xf wordpress-4.9.1-zh_CN.tar.gz
# ln -sv wordpress wp
# cp wp/wp-config-sample.php wp/wp-config.php
# vim wp/wp-config.php
define(‘DB_NAME’, ‘wordpress’);
define(‘DB_USER’, ‘wpuser’);
define(‘DB_PASSWORD’, ‘wppass’);
define(‘DB_HOST’, ‘172.16.0.69’);
网络访问: http://www.ilinux.io/wp
上传权限取决于apache用户于wp-content目录; 一般是静态资源所以只对172.16.0.68进行赋权;
172.16.0.68: # setfacl -R -m u:apache:rwx wp-content
提供phpMyadmin
# unzip phpMyAdmin-4.0.10.20-all-languages.zip
# ln -sv phpMyAdmin-4.0.10.20-all-languages pma
# cp pma/config.sample.inc.php pma/config.inc.php
$cfg[‘Servers’][$i][‘host’] = ‘172.16.0.69’;
因为动态内容在php-fpm，所以在那个主机有相同的目录
# unzip phpMyAdmin-4.0.10.20-all-languages.zip
# ln -sv phpMyAdmin-4.0.10.20-all-languages pma
# cp pma/config.sample.inc.php pma/config.inc.php
$cfg[‘Servers’][$i][‘host’] = ‘172.16.0.69’;
网页访问时，roo没有远程访问的权限；需要授权：
或者用wpuser, wppass登陆也行
(3) 提供xcache
先用ab压测；
172.16.0.69
# yum -y install httpd （提供ab命令）
# ab -n 10000 -c 10 http://172.16.0.67/pma/index.php
