1.试验环境：两台服务器为华为云提供的IaaS云
server1：CentOS Linux release 7.4.1708 (Core) 192.168.1.244/24
server2：CentOS Linux release 7.4.1708 (Core) 192.168.1.189/24
2.server1和server2共同配置
1.配置yum源，使用华为自己的yum源

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

yum clean all ; yum repolist ==>1万多个包出现即可以正常使用
2.server1搭建lnmp+redis
(1).网上下载redis需要用到的包：redis-4.0.8.tar.gz php-redis-2.2.4.tar.gz nginx-1.12.2.tar.gz
(2).搭建nginx
useradd nginx
tar -xf nginx-1.12.2.tar.gz
yum -y install gcc make zlib-devel pcre-devel
cd nginx-1.12.2
./configure --prefix=/usr/local/nginx
make && make install
/usr/local/nginx/sbin/nginx
echo lnmp >/usr/local/nginx/html/index.html
vim /usr/local/nginx/conf/nginx.conf
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi.conf;
}
/usr/local/nginx/sbin/nginx -s reload
curl 127.0.0.1
yum -y install php-fpm
systemctl restart php-fpm php-mysqlnd php-redis
vim /usr/local/nginx/html/test.php
<?php phpinfo();?>
curl 127.0.0.1/test.php
(3).搭建mariadb服务器
yum -y install mariadb mariadb-server
systemctl restart mariadb
systemctl enable mariadb
mysqladmin -uroot -p password "Lh123456"
mysql -uroot -p "Lh123456"
(4).搭建redis服务器，安装php-redis
tar -xf redis-4.0.8.tar.gz
cd redis-4.0.8
yum -y install gcc gcc-c++
make
make install
cd utils/
./install_server.sh
/etc/init.d/redis_6379 start
ss -anptu | grep :6379
redis-cli
tar -xf php-redis-2.2.4.tar.gz
cd phpredis-2.2.4/
phpize
./configure --with-php-config=/usr/bin/php-config
make && make install
vim /etc/php.ini
extension="redis.so"
extension_dir = "/usr/lib64/php/modules/"
systemctl restart php-fpm
php -m | grep -i redis ==>出结果，就能解析redis了
3.server2上可以搭建mariadb-server，server1的web网站连接server2进行正常访问
总结：server1上可以绑定一个弹性公网ip，用户访问这个公网ip，他连接server2的mysql数据库，能够正常展示数据，表示成功！
