1、Centos7系統庫中默認是沒有nginx的rpm包的，所以我們需要先更新下rpm依賴庫
(1)：使用yum安裝nginx，安裝nginx庫
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
(2)：使用下面命令安裝nginx
yum -y install nginx
(3)：啟動nginx
systemctl start nginx #centos7
查看nginx版本
nginx -v
nginx version: nginx/1.18.0
(4)：防火牆允許通過80端口-
(5)：重啟防火牆
systemctl start firewalld
(6)：訪問網站，輸入服務器ip地址，查看是否出現 'Welcome To Nginx'，如果想更改網站根目錄，修改地址：vim /etc/nginx/conf.d/default.conf，修改Root 后面的路徑
2、安裝Mysql，先更新yum源
(1)：yum源下載地址，根據自己需要的版本選擇相應的源
https://dev.mysql.com/downloads/repo/yum/
(2)：我們版本是6.x的，所以選擇linux 6 下載
wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm
(3)：安裝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)：安裝Mysql
yum -y install mysql-community-server
#時間有點長，稍微等一下
(6)：開始mysql服務
service mysqld start
(7)：Mysql安裝成功之后，會自動創建root的密碼，存儲在/var/log/mysqld.log，可以通過以下命令來查看
grep 'temporary password' /var/log/mysqld.log
(8)：登錄mysql，修改密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Wang123!';
(9)：開啟遠程鏈接，iptables開放3306端口
firewall-cmd --zone=public --add-port=3306/tcp --permanent
vim /etc/sysconfig/iptables （我自己沒找到這個文件，所以用上面命令開放了80和3306的端口）
(10)：重啟防火牆使iptables生效
systemctl start firewalld
3、安裝PHP（php-5.6）(根據自己要安裝的版本進行下載源碼包 https://www.php.net/releases/)
（1）cd /usr/local/src/
（2）下載：wget http://cn2.php.net/distributions/php-5.6.36.tar.gz
（3） 解壓源碼包，創建賬號
tar zxf php-5.6.36.tar.gz
useradd -s /sbin/nologin php-fpm
（4） 新建目錄：
mkdir /usr/local/php-fpm/etc
（5）配置編譯選項：#多了--enable-fpm，如果不加該參數，則不會有php-fpm執行文件生成，更不能啟動php-fpm服務
./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

（8）編譯php：
make
（9）安裝php
make install
（10）復制php配置文件到安裝目錄
cp php.ini-production /usr/local/php/etc/php.ini vim /usr/local/php/etc/php.ini //display_errors = On，顯示錯誤信息
（11）復制啟動腳本
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 前面的分號
（13）啟動php
/etc/init.d/php-fpm start //啟動 /etc/init.d/php-fpm stop //停止 /etc/init.d/php-fpm restart //重啟
ps -ef | grep php //查看php啟動狀態
（14）配置nginx.conf
vim /usr/local/nginx/conf/nginx.conf
（15）/usr/local/nginx/html中創建index.php，重啟php和nginx。
