部署nginx反向代理三個web服務，調度算法使用加權輪詢(由于物理原因只開啟兩臺服務器)

AutoNginxNfsService.sh

#/bin/bash systemctl status nginx if(($?==4))then yum install -y nginxif(($?==0))then#echo 'Yes!'systemctl start nginxif(($?==0))thenecho "Congratulations!!

所有web服務使用共享存儲nfs，保證所有web都對其有讀寫權限，保證數據一致性

#/bin/bash systemctl status nginx if(($?==4))thenyum install -y nginxif(($?==0))then#echo 'Yes!'systemctl start nginxif(($?==0))thenecho "Congratulations!! Nginx start OK!!"elseecho "Sorry is Fail!!!" fielseecho"sorry install is Fail!!!"fi elif(($?==3))thensystemctl start nginxif(($?==0))thenecho "Congratulations!!
