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.mysql.com/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 mysqldsystemctl 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YNew 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YSuccess.
- 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YSuccess.
- 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YSuccess.All done!
四、安装PHP
1.更新YUM源
- 添加epel源
yum install -y https://repo.ius.io/ius-release-el7.rpm https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
- 添加Webtatic源
rpm -Uvh https://mirror.webtatic.com/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.net/phpMyAdmin/4.0.10.20/phpMyAdmin-4.0.10.20-all-languages.zip
- 解压
yum install -y unzipunzip 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;
