Go to “Properties” of “jp2launcher.exe“. “Compatibility” tab -> “Change high DPI settings“. Check “Override high DPI scaling behavior….“. Select “System (Enhanced)” or “System“.
网上有很多关于如何在VMware Workstation上部署vCenter Server VCSA的文章，但根据这些文章在部署过程中总是会遇到各种各样。以下是几点我总结出来的要点，仅供参考。 我假设你的实验环境里没有DNS或者域服务器，只是简单的使用VMware Workstation的DHCP服务，虚拟机的网卡选择的是“host-only”。以下步骤仅用于做一些快速测试时使用。 vCenter Server安装好后第一次启动的时候会检测FQDN。如果你没有DNS服务器，FQDN检测会失败。所以在安装vCenter Server时要确保“Host Network Identity”输入的是IP地址。 OVA文件导入后虚拟机会立刻自动启动，有时候虚拟机的网卡可能会是断开状态的。要确保网卡是连接状态。 第一次启动耗时大约15至20分钟，在没有完全启动完毕前虚拟机的控制台界面是不现实IP地址的。另外一个vCenter Server准备就绪的表现是IP地址ping得通了。 vCenter Server第一次启动后，需要打开 https://vcenter_ip:5480 继续完成vCenter Server的配置。 [email protected] 的密码就是你在OVA导入界面里输入的密码。 2018 5月28日更新： 在以上步骤的第四步中，你可能无法登陆root，提示验证失败。这是由于root锁死造成的，需要按照以下步骤解锁： 重启vCenter Server虚拟机。 在Photon启动界面按“e”键。 在第二行结尾加入”rw init=/bin/bash“。具体参考这里。 当你看到#提示符时，运行命令”passwd“更改root密码。 运行命令”pam_tally2 –user root“检查root密码输入错了多少次。 如果输入错误次数大于1，运行命令 “pam_tally2 –user root –reset” 解锁root账号。 重启虚拟机，现在应该可以登录了。 2018 5月31日更新： 在以上步骤的第四步中，登陆后你应该会看到vCenter Server安装向导。如果你的vCenter Server只想用IP地址，请确保“System name”项填写的是IP地址。
