| DNS | DNS | CentOS7.6 | 192.168.73.101 |
| HTTPD+php | HTTPD | CentOS7.6 | 192.168.73.110 |

一、搭建MySQL主从
在所有MySQL服务器安装MySQL服务
yum install mariadb-server -yMaster节点操作
1.配置主节点服务器
[[email protected] ~]# vim /etc/my.cnf
[mysqld]
server-id=1
log-bin=/data/bin/mysql-bin
binlog-format=row2.创建二进制日志目录
[mysqld]
server-id=1
log-bin=/data/bin/mysql-bin
binlog-format=row3.启动MySQL服务
[[email protected] ~]# systemctl start mariadb4.创建一个用来主从复制的账号
[[email protected] ~]# 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
[[email protected] ~]# 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
[[email protected] ~]# vim /etc/my.cnf
[mysqld]
server-id=2
read-only2.启动服务
[[email protected] ~]# systemctl start mariadb3.CHANGE MASTER TO
[[email protected] ~]# mysql

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
[[email protected] ~]# 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
[[email protected] ~]# 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
[[email protected] ~]# vim /etc/php-fpm.d/www.conf
;listen = 127.0.0.1:9000
listen = /var/run/php.sock
listen.mode = 0666
;listen.allowed_clients = 127.0.0.14.修改php.ini中时区
[[email protected] ~]# vim /etc/php.ini
date.timezone = Asia/Shanghai5.启动httpd、php-fpm
[[email protected] ~]# systemctl start httpd php-fpm6.创建测试页
[[email protected] ~]# mkdir /data/test
[[email protected] ~]# 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
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
[[email protected] ~]# scp /etc/httpd/conf/httpd.conf 192.168.73.111:/etc/httpd/conf/httpd.conf
[[email protected] ~]# scp /etc/php-fpm.d/www.conf 192.168.73.111:/etc/php-fpm.d/www.conf 2.启动服务
[[email protected] ~]# systemctl start httpd php-fpm 3.创建测试页
[[email protected] ~]# mkdir /data/test
[[email protected] ~]# 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
配置dns服务器
1.安装bind服务
[[email protected] ~]# yum install bind -y2.修改主配置文件
[[email protected] ~]# 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
[[email protected] ~]# 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
[[email protected] etc]# cp -p /var/named/named.localhost /var/named/mylinuxops.com.zone
[[email protected] 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 192.168.73.1115.检查语法错误
[[email protected] etc]# named-checkconf
[[email protected] etc]# named-checkzone mylinuxops.com /var/named/mylinuxops.com.zone
zone mylinuxops.com/IN: loaded serial 0
OK6.启动服务
