云计算之lnmp + redis

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

     注意：其update部分的enabled=1改成0 ==》该镜像有些问题

     rm -rf /etc/yum.repos.d/*

      rm -rf /etc/yum.repos.d/huawei.repo

# CentOS-Base.repo

#

# 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！
