x86_64:https://update.cs2c.com.cn/NS/V10/V10SP2/os/adv/lic/updates/x86_64/
2. 配置完成后執(zhí)行更新命令進(jìn)行升級(jí)，命令如下：
yum update Packagename
方法二：下載安裝包進(jìn)行升級(jí)安裝
通過軟件包地址下載軟件包，使用軟件包升級(jí)命令根據(jù)受影響的軟件包列表進(jìn)行升級(jí)安裝,命令如下：
yum install Packagename
3. 升級(jí)完成后是否需要重啟服務(wù)或操作系統(tǒng)：
·CVE-2019-12293：無需重啟操作系統(tǒng)與服務(wù)即可使漏洞修復(fù)生效。
·CVE-2020-27778：無需重啟操作系統(tǒng)與服務(wù)即可使漏洞修復(fù)生效。
