1、Centos7系统库中默认是没有nginx的rpm包的，所以我们需要先更新下rpm依赖库
(1)：使用yum安装nginx，安装nginx库
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
(2)：使用下面命令安装nginx
yum -y install nginx
(3)：启动nginx
systemctl start nginx #centos7
查看nginx版本
nginx -v
nginx version: nginx/1.18.0
(4)：防火墙允许通过80端口-
(5)：重启防火墙
systemctl start firewalld
(6)：访问网站，输入服务器ip地址，查看是否出现 'Welcome To Nginx'，如果想更改网站根目录，修改地址：vim /etc/nginx/conf.d/default.conf，修改Root 后面的路径
2、安装Mysql，先更新yum源
(1)：yum源下载地址，根据自己需要的版本选择相应的源
https://dev.mysql.com/downloads/repo/yum/
(2)：我们版本是6.x的，所以选择linux 6 下载
wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm
(3)：安装mysql的yum源
rpm -Uvh mysql57-community-release-el6-11.noarch.rpm
或
yum -y localinstall mysql57-community-release-el6-11.noarch.rpm
(4)：查看是否配置mysql源成功
在/etc/yum.repos.d下面
(5)：安装Mysql
yum -y install mysql-community-server
#时间有点长，稍微等一下
(6)：开始mysql服务
service mysqld start
(7)：Mysql安装成功之后，会自动创建root的密码，存储在/var/log/mysqld.log，可以通过以下命令来查看
grep 'temporary password' /var/log/mysqld.log
(8)：登录mysql，修改密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Wang123!';
(9)：开启远程链接，iptables开放3306端口
firewall-cmd --zone=public --add-port=3306/tcp --permanent
vim /etc/sysconfig/iptables （我自己没找到这个文件，所以用上面命令开放了80和3306的端口）
(10)：重启防火墙使iptables生效
systemctl start firewalld
3、安装PHP（php-5.6）(根据自己要安装的版本进行下载源码包 https://www.php.net/releases/)
（1）cd /usr/local/src/
（2）下载：wget http://cn2.php.net/distributions/php-5.6.36.tar.gz
（3） 解压源码包，创建账号
tar zxf php-5.6.36.tar.gz
useradd -s /sbin/nologin php-fpm
（4） 新建目录：
mkdir /usr/local/php-fpm/etc
（5）配置编译选项：#多了--enable-fpm，如果不加该参数，则不会有php-fpm执行文件生成，更不能启动php-fpm服务
./configure > --prefix=/usr/local/php-fpm > --with-config-file-path=/usr/local/php-fpm/etc > --enable-fpm > --with-fpm-user=php-fpm > --with-fpm-group=php-fpm > --with-mysql=/usr/local/mysql > --with-mysql-sock=/tmp/mysql.sock > --with-libxml-dir > --with-gd > --with-jpeg-dir > --with-png-dir > --with-freetype-dir > --with-iconv-dir > --with-zlib-dir > --with-mcrypt > --enable-soap > --enable-gd-native-ttf > --enable-ftp > --enable-mbstring > --enable-exif > --disable-ipv6 > --with-pear > --with-curl > --with-openssl
（6）可能会出现的错误

（8）编译php：
make
（9）安装php
make install
（10）复制php配置文件到安装目录
cp php.ini-production /usr/local/php/etc/php.ini vim /usr/local/php/etc/php.ini //display_errors = On，显示错误信息
（11）复制启动脚本
cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
（12）修改php-fpm配置文件
cd /usr/local/php/etc cp php-fpm.conf.default php-fpm.conf vim php-fpm.conf //去掉 pid = run/php-fpm.pid 前面的分号
（13）启动php
/etc/init.d/php-fpm start //启动 /etc/init.d/php-fpm stop //停止 /etc/init.d/php-fpm restart //重启
