Third test

 

nfs: 192.168.1.40

rp1: 192.168.1.41

rp2: 192.168.1.42

mariadb: 192.168.1.43

web2: 192.168.1.111

app1: 192.168.1.112

app2: 192.168.1.113

實驗效果：用keepalived高可用反向代理服務器haproxy，將靜態頁面反代到varnish緩存服務器，動態頁面反代到后端的app服務器，訪問內容如果在緩存服務器上有緩存，就直接返回，如果沒有就到后端web服務器取

  2. vim /etc/exports

  3. chmod o+w /mnt/share

//給目錄一個寫權限，因為之后要將此目錄掛載到web和app服務上，以備上傳圖片
