小型LAMP搭建

一、dns的搭建

安装dns服务

yum install bind

修改dns的主配置文件

  1 [root@234c17 named]# vim /etc/named.conf
  2
  3 //
  4
  5 // named.conf
  6
  7 //
  8
  9 // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
 10
 11 // server as a caching only nameserver (as a localhost DNS resolver only).
 12
 13 //
 14
 15 // See /usr/share/doc/bind*/sample/ for example named configuration files.
 16
 17 //
 18
 19 // See the BIND Administrator's Reference Manual (ARM) for details about the
 20
 21 // configuration located in /usr/share/doc/bind-{version}/Bv9ARM.html
 22
 23 options {
 24
 25 //      listen-on port 53 { 127.0.0.1; };  //将其注释掉，
 26
 27         listen-on-v6 port 53 { ::1; };
 28
 29         directory       "/var/named";
 30
 31         dump-file       "/var/named/data/cache_dump.db";
 32
 33         statistics-file "/var/named/data/named_stats.txt";
 34
 35         memstatistics-file "/var/named/data/named_mem_stats.txt";
 36
 37 //      allow-query     { localhost; };  //将其注释掉，
 38 

修改dns服务的rfc192.zones，增加zone

  1 [root@234c17 named]# vim /etc/named.rfc1912.zones
  2
  3 // named.rfc1912.zones:
  4
  5 //
  6
  7 // Provided by Red Hat caching-nameserver package
  8
  9 //
 10
 11 // ISC BIND named zone configuration for zones recommended by
 12
 13 // RFC 1912 section 4.1 : localhost TLDs and address zones
 14
 15 // and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
 16
 17 // (c)2007 R W Franks
 18
 19 //
 20
 21 // See /usr/share/doc/bind*/sample/ for example named configuration files.
 22
 23 //
 24
 25 zone "gdkj.com" IN {
 26
 27         type master;
 28
 29         file "gdkj.com.zone";
 30
 31 };

新建zone文件

  1 [root@234c17 named]#  vim gdkj.com.zone
  2
  3 $TTL 1D
  4
  5 @ IN SOA dns1 admin.gdkj.com. ( 1 1D 3H 1W 2D )
  6
  7         NS dns1
  8
  9 dns1    A  192.168.234.17
 10
 11 www     A  192.168.234.27
 12
 13 www     A  192.168.234.37

修改windows的dns地址后windows能通

mysql的准备

 //安装mysql服务启动

yum install mariadb-server

systemctl start mariadb

创建wordpress数据库和帐号

  1 MariaDB [(none)]> create database wpdb
  2
  3     -> ;
  4
  5 Query OK, 1 row affected (0.00 sec)
  6
  7 MariaDB [(none)]> grant all on wpdb.* to wpuser@"192.168.234.27" identified by "centos";
  8
  9 Query OK, 0 rows affected (0.00 sec)
 10
 11 MariaDB [(none)]> grant all on wpdb.* to wpuser@"192.168.234.37" identified by "centos";

nfs服务配置在此共享wordpress目录

下载worfpress软件包 准备配置文件

mkdir -p /data/www

tar xf wordpress-4.9.4-zh_CN.tar.gz -C /data/

cd /data/

mv wordpress www

mv wp-config-sample.php  wp-config.php

wordpress与mysql的连接的修改

  1 [root@234c47 exports.d]# vim wp-config.php
  2
  3 // ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
  4
  5 /** WordPress数据库的名称 */
  6
  7 define('DB_NAME', 'wpdb');
  8
  9 /** MySQL数据库用户名 */
 10
 11 define('DB_USER', 'wpuser');
 12
 13 /** MySQL数据库密码 */
 14
 15 define('DB_PASSWORD', 'centos');
 16
 17 /** MySQL主机 */
 18
 19 define('DB_HOST', '192.168.234.57');

现在配置nfs的共享

[root@234c47 exports.d]# vim /etc/exports.d/www.exports  ///新建共享配置文件

/data/www 192.168.234.0/24(rw,all_squash,anonuid=48,anongid=48)

//让webservice1和webservice2拥有本机wordpress的共享权限

useradd -u 48 apache  //然后新建一个apache帐号

systemctl start nfs-server  //配置完成启动服务

web服务的配置

上面已经搭建好了mysql 准备好了wordpress文件及nfs共享

那么现在将远程的nfs共享目录挂载到本机目录

安装服务

yum install httpd php-fpm php-mysql

//修改webservice1的的配置 

[root@234c27 httpd]# vim /etc/fstab

192.168.234.47:/data/www /var/www/html nfs    defaults        0 0

//修改webservice1的的配置

[root@234c37 httpd]# vim /etc/fstab

192.168.234.47:/data/www /var/www/html/ nfs    defaults        0 0

修改代理webserivce1

  1 [root@234c27 httpd]# vim /etc/httpd/conf.d/fcgi.conf
  2
  3 ProxyRequests Off
  4
  5 ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1

修改代理webserivce2

  1 [root@234c37 httpd]# vim /etc/httpd/conf.d/fcgi.conf
  2
  3 ProxyRequests Off
  4
  5 ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1

测试成功

备注：

一、期间因为挂载目录的不熟悉，将192.168.234.47:/data/www 挂载自本机的/var/www/html/www 导致错误。

二、实验图可扩展为dns的泛域名解析以及nfs的rsync和mysql的主从，及其他高可用
