Shell脚本-自动化部署反向代理、WEB、nfs

部署nginx反向代理三个web服务，调度算法使用加权轮询(由于物理原因只开启两台服务器)

AutoNginxNfsService.sh

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

elif(($?==0))thenecho "OKOKOK!!!"
else echo "I am so sorry"    
fi
echo "config writing...."

echo "config write is OK!"
systemctl reload nginx

else echo "I am so sorry"    
fi
echo "config writing...."
echo "/webindex 192.168.16.0/24(rw,sync,fsid=0)" > /etc/exports
echo "config write is OK!"
systemctl reload nfs
if(($?==0))thenecho "NFS service is OK!"
elseecho "Sorry!!"
fi

所有web服务使用共享存储nfs，保证所有web都对其有读写权限，保证数据一致性

#/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(($?==0))thenecho "Congratulations!! Nginx start OK!!!"elseecho "sorry!!"fi
elif(($?==0))thenecho "OKOKOK!!!"
elseecho "I am so sorry"    
fi
echo "config writing...."
sed -ri '/^(\ +)(location)(\ )(\/)/a root\ \/nginxwebservice\;' /etc/nginx/nginx.conf
sed -ri '/^root\ \/nginxwebservice/a index\ web.html\;' /etc/nginx/nginx.conf
echo "config write is OK!"
systemctl reload nginx
