1. 准备 Nginx + PHP 环境
安装 Nginx
使用 yum 安装 Nginx：
yum install nginx修改 /etc/nginx/nginx.conf 文件为如下内容：
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf; events { worker_connections 1024; } http { log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; include /etc/nginx/conf.d/*.conf; server { listen 80; server_name 127.0.0.1; root /var/www/html; index index.php index.html error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } location ~ .php$ { root /var/www/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~ /.ht { deny all; } } }启动 Nginx 并设置为开机启动：
service nginx start
chkconfig nginx on安装 PHP
使用 yum 安装 php-fpm：
yum install php php-gd php-fpm php-mcrypt php-mbstring php-mysql php-pdo启动 php-fpm 并设置为开机启动：
service php-fpm start
chkconfig php-fpm on
2. 创建项目
下载安装 Composer
Composer 是 PHP 的一个依赖管理工具，推荐使用 Composer 创建 ShowDoc 项目。
执行如下命令安装 Composer：
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
设置 Composer 使用国内镜像
执行命令设置 Composer 使用国内镜像：
composer config -g repo.packagist composer https://packagist.phpcomposer.com使用 Composer 创建项目
执行命令创建项目：
cd /var/www/html/ && composer create-project showdoc/showdoc设置 showdoc 目录写权限
执行命令赋予 showdoc 下部分目录的写权限
chmod a+w showdoc/install
chmod a+w showdoc/Sqlite
chmod a+w showdoc/Sqlite/showdoc.db.php
chmod a+w showdoc/Public/Uploads/
chmod a+w showdoc/Application/Runtime chmod a+w showdoc/server/Application/Runtime chmod a+w showdoc/Application/Common/Conf/config.php chmod a+w showdoc/Application/Home/Conf/config.php创建完毕，您现在可以通过浏览器访问 http://yourip/showdoc/install/ 或 http://yourdomain.com/showdoc/install/ ，进行语言的选择以后即可通过 http://yourip/showdoc 或 http://yourdomain/showdoc 查看站点效果。
