LAMP环境搭建+配置虚拟域名

Centos下PHP，Apache，Mysql 的安装

安装Apache

    yum -y install httpd
    systemctl start httpd

添加防火墙

    firewall-cmd --permanent --add-port=80/tcp
    systemctl restart firewalld

安装PHP7.2

    yum install epel-release -y
    rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
    yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
    systemctl restart httpd
    systemctl enable php-fpm.service
    systemctl start php-fpm.service

安装mysql

    yum -y install wget
    wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
    rpm -ivh mysql57-community-release-el7-9.noarch.rpm
    cd yum.repos.d
    yum install -y mysql-server
    service mysqld start

mysql密码配置

　　新版本的Mysql会为root用户创建一个初始密码，需要更改
　　查看默认密码

    sudo grep 'temporary password' /var/log/mysqld.log
    2020-01-16T01:47:12.600702Z 1 [Note] A temporary password is generated for root@localhost: nym>Co+s7oK2

更改Mysql密码

    cd /etc
    vi my.cnf
    新增 skip-grant-tables
    不用密码直接登录mysql ： mysql
    修改密码（5.7版本已经不再使用password来作为密码的字段了  而改成了authentication_string）
    UPDATE mysql.user SET authentication_string=PASSWORD("123456") WHERE user="root" AND Host="localhost";
    刷新表格
    flush privileges;
    退出mysql: exit;
    systemctl restart mysqld

配置虚拟域名

查看apache主配置文件，确保存在以下配置

    vim  /etc/httpd/conf/httpd.conf 
    IncludeOptional conf.d/*.conf

新增虚拟主机配置文件

    cd /etc/httpd/conf.d/
    vim cyy.conf

添加虚拟机

    <VirtualHost *:80>
        ServerName lamp.cyy.com
        ServerAlias lamp.cyy.com
        ServerAdmin lamp@cyy.com
        DocumentRoot /var/www/html/lamp.cyy.com/

        <Directory /var/www/html/lamp.cyy.com>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        </Directory>

        ErrorLog /var/log/httpd/lamp.cyy.com-error.log
        CustomLog /var/log/httpd/lamp.cyy.com-access.log combined
    </VirtualHost>

创建虚机主机目录及测试页面

/var/www/html/lamp.cyy.com/

创建info.php

    <?php
    phpinfo();

在/etc/hosts文件中新增

    192.168.23.130 lamp.cyy.com
    #虚拟机ip

检查配置文件是否正常

    httpd -t
    AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
    Syntax OK

重启httpd服务

    systemctl restart httpd

在本机我是win10，路径：C:\Windows\System32\drivers\etc
hosts文件中新增

    192.168.23.130 lamp.cyy.com
