1.工作形容
须要创立一个脚本，在Windows主机时区发生变化时，通过执行脚本，同步时区变动到Linux服务器上。2.设计思路
- 应用xml文件配置服务器相干参数。
- 应用plink将生成的管制命令推送到服务器上。
3.原理
- tzselect命令无奈批改时区，仅给出时区的城市表示法
- 默认状况下状况下，tz属性是空，这时候是靠/etc/localtime文件来确定的时区。而此文件通常又是一个到/usr/share/zoneinfo/下各种时区文件的软连贯。通过批改/etc/localtime指向的软连贯，进而批改零碎的时区。例如：
cp /us/share/zoneinfo/Etc/GMT-8 /etc/localtime- 须要root权限执行上述操作，故须要事后批改权限限度
sudo chmod 777 /etc/localtime
4.相干程序
1. /Program/CCBConfiguration.xml是配置文件
- LoginUser 登录Linux的用户名
- Password 登录Linux的用户明码
- HostName Linux设施IP地址
其余项暂未应用
<Document><LoginUser>***</LoginUser><Password>***</Password><HostName>*.*.*.*</HostName><UploadPath>pass</UploadPath><InstallParameter>pass</InstallParameter><InstallLogPath>pass</InstallLogPath></Document>
