查看nginx啟動了多久
ps -p cat /run/nginx.pid -o etime=
測試，在/etc/nginx/conf.d/添加新的server app1, app2
server {
listen 80;
servername app1.com www.app1.com;
location / {
root /usr/share/nginx/html/app1;
}
}
server {
listen 80;
servername app2.com www.app2.com;
location / {
root /usr/share/nginx/html/app2;
}
}
在創(chuàng)建/usr/share/ngin/html 下創(chuàng)建 app1/index.html 和 app2/index.html
重啟nginx: nginx -s reload
訪問172.16.20.79 默認(rèn)app1.com， 再訪問app1.com 和 app2.com
修改端口,跳到默認(rèn)default_server或者順序第一個可以提供服務(wù)的server
在 app2.com的server配置中陨囊，在listen 80后面加 default_server ,然后訪問172.16.20.79镊绪，頁面顯示app2.com
如果不希望相應(yīng)沒有host HTTP頭的，添加下面的配置
server {
listen 80;
server_name "" localhost 127.0.0.1 172.16.20.79;
return 444; # 不響應(yīng)带欢，并關(guān)閉連接
}

最長匹配原則
~* 不分大小寫匹配
~ 區(qū)分大小寫匹配
^~ uri如果開頭等于這個值运授，不再嘗試正則匹配
= 精準(zhǔn)匹配，將常用URL用這個寫法乔煞，可以提供性能徒坡，因?yàn)閚ginx不需要進(jìn)行搜索
