1. 连接mysql，新建wordpress数据库

mysql -u root -p
CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

2.新建并进入准备放html的目录

cd /usr/share/nginx 
mkdir wp
cd wp

3.授权

chown -R www-data:www-data ./

4.下载、解压

#下载
sudo wget http://wordpress.org/latest.tar.gz
#解压，并把文件移动到当前根目录下
tar -xvf latest.tar.gz
mv wordpress/* ./

5.配置nginx

 server{
    listen 80;
    server_name wp.domain.com;#换成你的域名
    root /usr/share/nginx/wp;#换成你的路径
    index index.html index.htm index.php;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }
    location ~ \.php$ {
        try_files $uri =404;

        include fastcgi.conf;
        fastcgi_pass 127.0.0.1:9000;
    }
}

6.重启nginx

service nginx restart

7.访问域名，做一些简单配置

输入相应的数据库信息，网站信息，用户名密码信息，就完成配置了。
