CentOS7 配置LAMP环境

一、关闭防火墙

1.查看防火墙状态

systemctl status firewalld

• inactive 关闭状态
• active  开启状态

2.关闭防火墙

systemctl stop firewalld

3.永久关闭防火墙

systemctl disable firewalld

二、安装Apache

1.安装Apache服务及扩展包

yum -y install httpd httpd-manual mod_ssl mod_perl mod_auth_mysql

2.启动Apache服务

systemctl start httpd

3.设置Apache服务开机自启动

systemctl enable httpd

4.查看apache是否安装成功

在浏览器地址栏输入 http://ip地址，运行，出现如下页面即安装成功

 

 

三、安装并配置MySQL

 　1.更新YUM源

rpm -Uvh  http://dev./get/mysql57-community-release-el7-9.noarch.rpm

　2.安装MySQL

yum -y install mysql-community-server

　　如果出现”No match for argument“错误，请先运行yum module disable mysql禁用默认的mysql模块，再安装MySQL

　3.查看MySQL版本号

mysql -V

　出现如下信息即表示安装成功，注意”V“要大写

 

 

　 4.启动mysql

systemctl start mysqld

　5.设置开机自启动

systemctl enable mysqld
systemctl daemon-reload

　6.查看初始密码

grep "password" /var/log/mysqld.log

　　

　7.配置MySQL的安全性

mysql_secure_installation

• 重置root账号的密码

Enter password for user root: #输入上一步获取的root用户初始密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration of the plugin.
Using existing password for root.
Estimated strength of the password: 100 
Change the password for root ? (Press y|Y for Yes, any other key for No) : Y #是否更改root用户密码，输入Y
New password: #输入新密码，长度为8至30个字符，必须同时包含大小写英文字母、数字和特殊符号。特殊符号可以是()` ~!@#$%^&*- =|{}[]:;‘<>,.?/
Re-enter new password: #再次输入新密码
Estimated strength of the password: 100 
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : Y

• 输入Y删除匿名用户账号

By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y  #是否删除匿名用户，输入Y
Success.

• 输入Y禁止root账号远程登录

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y #禁止root远程登录，输入Y
Success.

• 输入Y删除test库以及对test库的访问权限

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y #是否删除test库和对它的访问权限，输入Y
- Dropping test database...
Success.

• 输入Y重新加载授权表

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y #是否重新加载授权表，输入Y
Success.
All done!

四、安装PHP

　1.更新YUM源

• 添加epel源

yum install -y https://repo./ius-release-el7.rpm https://dl./pub/epel/epel-release-latest-7.noarch.rpm

• 添加Webtatic源

rpm -Uvh https://mirror./yum/el7/webtatic-release.rpm

　　2.安装PHP

yum -y install php70w-devel php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64  php70w-pdo.x86_64   php70w-mysqlnd  php70w-fpm php70w-opcache php70w-pecl-redis php70w-pecl-mongodb

　　3.查看PHP版本

php -v

　　出现如下结果即表示php安装成功

　4.在Apache网站根目录创建测试文件

echo "<?php phpinfo(); ?>" > /var/www/html/phpinfo.php

　5.重启Apache服务

systemctl restart httpd

　6.运行。在浏览器地址栏输入http://ip地址/phpinfo.php，出现如下页面即表示安装成功

 

 

 五、安装phpMyAdmin

　1.创建phpMyAdmin数据存放目录

mkdir -p /var/www/html/phpmyadmin

　2.下载phpMyAdmin压缩包并解压

• 下载

wget https://files./phpMyAdmin/4.0.10.20/phpMyAdmin-4.0.10.20-all-languages.zip

• 解压

yum install -y unzip
unzip phpMyAdmin-4.0.10.20-all-languages.zip

　3.复制phpMyAdmin文件到准备好的数据存放目录

mv phpMyAdmin-4.0.10.20-all-languages/*  /var/www/html/phpmyadmin

　4.检查是否安装成功。在浏览器地址栏输入http://ip地址/phpmyadmin，运行，出现如下页面即表示安装成功

　

 

LAMP环境配置完成！

如果使用navicat连接数据库报错，ERROR 1130: Host xxx.xxx.xxx.xxx is not allowed to connect to this MySQL server，是无法给远程连接的用户权限问题，就是”7.配置MySQL的安全性“中第三步设置了禁止远程登陆

解决办法：

mysql -u root -p密码

　　进入Mysql控制台

• 提权

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION; 

• 刷新

flush privileges;
