看書上說nginx比apache強大，好奇之下(其實是因為nginx安裝手冊比較薄)就開始
裝nginx。目前在nginx server block的步驟，但看不太懂><
一坨長這樣：
server {
listen 80;
server_name nginxsite.com
www.nginxsite.com;
location / {
root /var/www/nginxsite.com/public_html;
index index.html index.htm;
try_files $uri $uri/ =404;
} error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
