升级ExaGear for Server on CentOS
升级前准备
1. 确保host 系统已安装ExaGear for Server
2. 将ExaGear for Server的所有配置文件拷贝至host系统目录备份：
1 | cp -r /opt/exagear/images/centos-<os_version>-x86_64/.exagear/* /tmp |
升级步骤
1. 运行rpm命令升级ExaGear for Server软件包。
CentOS with 4KB page size系统下：
1 | sudo rpm -Uvh exagear-utils-<package_version>.noarch.rpm exagear-core-x64a64-<package_version>.aarch64.rpm exagear-core-x32a64-<package_version>.aarch64.rpm exagear-guest-<package_version>.noarch.rpm exagear-integration-<package_version>.noarch.rpm exagear-cfg-builder-a64-<package_version>-1.aarch64.rpm |
2. 将备份的ExaGear for Server配置文件与升级后的默认配置文件合并，以共享目录vpath-list配置文件为例，执行以下命令：
1 | cat /tmp/vpath-list /opt/exagear/images/centos-<os_version>-x86_64/.exagear/vpaths-list |sort|uniq > /opt/exagear/images/centos-<os_version>-x86_64/.exagear/vpaths-list |
升级后检查
通过以下命令确认升级后的ExaGear for Server 版本：
1 | /opt/exagear/bin/ubt_x64a64_al -v
|
Revision 与 <package_version> 一致则表示升级完成。
新版本ExaGear for Server on CentOS将安装在旧版本上。所有guest系统中的Linux on x86 应用程序及ExaGear for Server on CentOS的相关配置均将保留。
