一、搭建MySQL主从

在所有MySQL服务器安装MySQL服务

yum install mariadb-server -y

Master节点操作

1.配置主节点服务器

[root@master ~]# vim /etc/my.cnf
[mysqld]
server-id=1
log-bin=/data/bin/mysql-bin
binlog-format=row

2.创建二进制日志目录

[mysqld]
server-id=1
log-bin=/data/bin/mysql-bin
binlog-format=row

3.启动MySQL服务

[root@master ~]# systemctl start mariadb

4.创建一个用来主从复制的账号

[root@master ~]# mysql -e "GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'192.168.73.%' IDENTIFIED BY '111111';"

5.查看二进制日志，记录日志大小

[root@master ~]# mysql -e "SHOW MASTER LOGS;"
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000001 |     26753 |
| mysql-bin.000002 |    921736 |
| mysql-bin.000003 |       402 |
+------------------+-----------+

Slave1节点操作

1.修改配置文件

[root@slave1 ~]# vim /etc/my.cnf
[mysqld]
server-id=2
read-only

2.启动服务

[root@slave1 ~]# systemctl start mariadb

3.CHANGE MASTER TO

[root@slave1 ~]# mysql
MariaDB [(none)]> CHANGE MASTER TO   MASTER_HOST='192.168.73.130',   MASTER_USER='repluser',   MASTER_PASSWORD='111111',   MASTER_PORT=3306,   MASTER_LOG_FILE='mysql-bin.000003',   MASTER_LOG_POS=402;
Query OK, 0 rows affected (0.01 sec)

+--------------------+
5 rows in set (0.00 sec)

数据库主从搭建完毕

二、搭建HTTPD+PHP

分别在两台httpd主机上安装httpd和php-fpm

yum install httpd php-fpm php-mysql -y

配置httpd服务器

1.查看fcgi相关模块是否启用

[root@httpd ~]# httpd -M | grep proxy
 proxy_module (shared)                      #已经启用
 proxy_ajp_module (shared)
 proxy_balancer_module (shared)
 proxy_connect_module (shared)
 proxy_express_module (shared)
 proxy_fcgi_module (shared)                 #已经启用
 proxy_fdpass_module (shared)
 proxy_ftp_module (shared)
 proxy_http_module (shared)
 proxy_scgi_module (shared)
 proxy_wstunnel_module (shared)

2.修改httpd配置文件

[root@httpd ~]# vim /etc/httpd/conf/httpd.conf 
    DirectoryIndex index.php index.html

addtype application/x-httpd-php .php
addtype applictaion/x-httpd-php-source .phps
proxyrequests off
proxyPassMatch ^/(.*\.php)$ unix:/var/run/php.sock|fcgi://localhost/data/test/$1

<Virtualhost *:80>
servername blog.mylinuxops.com
Documentroot /data/test
<directory /data/test>
require all granted
</directory>
</Virtualhost>

3.修改php-fpm配置文件

[root@httpd ~]# vim /etc/php-fpm.d/www.conf 
;listen = 127.0.0.1:9000
listen = /var/run/php.sock
listen.mode = 0666
;listen.allowed_clients = 127.0.0.1

4.修改php.ini中时区

[root@httpd ~]# vim /etc/php.ini 
date.timezone = Asia/Shanghai

5.启动httpd、php-fpm

[root@httpd ~]# systemctl start httpd php-fpm

6.创建测试页

[root@httpd ~]# mkdir /data/test
[root@httpd ~]# vim /data/test/index.php
<?php
$dsn='mysql:host=192.168.73.130;dbname=test';
$username='repluser'; $passwd='111111';
$dbh=new PDO($dsn,$username,$passwd);
var_dump($dbh);
phpinfo();
?>

7.测试
小型LAMP架构搭建

配置httpd2服务器

1.从httpd服务器将httpd配置文件及php-fpm配置文件复制至httpd2

[root@httpd ~]# scp /etc/httpd/conf/httpd.conf  192.168.73.111:/etc/httpd/conf/httpd.conf 
[root@httpd ~]# scp /etc/php-fpm.d/www.conf 192.168.73.111:/etc/php-fpm.d/www.conf

2.启动服务

[root@httpd2 ~]# systemctl start httpd php-fpm

3.创建测试页

[root@httpd ~]# mkdir /data/test
[root@httpd ~]# vim /data/test/index.php
<?php
$dsn='mysql:host=192.168.73.130;dbname=test';
$username='repluser'; $passwd='111111';
$dbh=new PDO($dsn,$username,$passwd);
var_dump($dbh);
phpinfo();
?>

4.测试
小型LAMP架构搭建

配置dns服务器

1.安装bind服务

[root@dns ~]# yum install bind -y

2.修改主配置文件

[root@dns ~]# vim /etc/named.conf 
//      listen-on port 53 { 127.0.0.1; };
//      listen-on-v6 port 53 { ::1; };

//      allow-query     { localhost; };

3.添加区域记录

[root@dns ~]# vim /etc/named.rfc1912.zones 
zone "mylinuxops.com" IN {
        type master;
        file "mylinuxops.com.zone";
};

4.创建区域数据库文件

[root@dns etc]# cp -p /var/named/named.localhost /var/named/mylinuxops.com.zone
[root@dns etc]# vim /var/named/mylinuxops.com.zone 
$TTL 1D
@       IN SOA  master admin.mylinuxops.com (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      master
master  A       192.168.73.101
www     A       192.168.73.110
www     A       192.168.73.111

5.检查语法错误

[root@dns etc]# named-checkconf 
[root@dns etc]# named-checkzone mylinuxops.com /var/named/mylinuxops.com.zone 
zone mylinuxops.com/IN: loaded serial 0
OK

6.启动服务

[root@dns etc]# systemctl start named

7.测试

[root@dns etc]# dig www.mylinuxops.com @192.168.73.101

配置NFS服务

1.创建出需要共享的目录，修改权限

[root@localhost ~]# mkdir /data/test/
[root@localhost ~]# setfacl -R -m u:nfsnobody:rwx /data/test

2.修改配置文件

[root@localhost ~]# vim /etc/exports
/data/test *(rw)

3.在httpd挂载nfs

[root@httpd ~]# showmount -e 192.168.73.120

4.在httpd2上挂载nfs

[root@httpd2 ~]# showmount -e 192.168.73.120
Export list for 192.168.73.120:
/data/test *
[root@httpd2 ~]# mount 192.168.73.120:/data/test /data/test

5.在/data/test中创建测试页

<?php
$dsn='mysql:host=192.168.73.130;dbname=test';
$username='repluser'; $passwd='111111';
$dbh=new PDO($dsn,$username,$passwd);
var_dump($dbh);

2.测试站点访问
小型LAMP架构搭建

测试安装wordpress

1.解压wordpress到/data/test

[root@httpd ~]# tar wordpress-5.0.3-zh_CN.tar.gz -C /data/test/

2.创建wordpress所需数据库及账户

[root@master ~]# mysql -e "CREATE DATABASE wordpress"
[root@master ~]# mysql -e "GRANT ALL ON wordpress.* TO 'wpuser'@'192.168.73.%' IDENTIFIED BY '111111';"

3.修改wordpress配置文件

[root@httpd ~]# cp /data/test/wordpress/wp-config-sample.php /data/test/wordpress/wp-config.php
[root@httpd ~]# vim /data/test/wordpress/wp-config.php
// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wpuser');

/** MySQL数据库密码 */
define('DB_PASSWORD', '111111');

/** MySQL主机 */
define('DB_HOST', '192.168.73.130');
