解決VMware 虛擬機中Linux系統時間不準確問題（安裝VMware Tools）

環境介紹：

 CentOS 7.5

 VMware Workstation 15 pro

安裝VMware Tools：

 選中要安裝VMware Tools的虛擬機，點擊鼠標右鍵，點擊安裝 VMware Tools。如果安裝了早期版本的 VMware Tools，則菜單項是更新 VMware Tools。

創建掛載點目錄並掛載

[root@test2 ~]# mkdir /mnt/cdrom

[root@test2 ~]# mount /dev/cdrom /mnt/cdrom
mount: /dev/sr0 寫保護，將以只讀方式掛載

[root@test2 ~]# df -h
文件系統                 容量  已用  可用 已用% 掛載點
/dev/mapper/centos-root   17G   12G  5.6G   68% /

/dev/sr0                  55M   55M     0  100% /mnt/cdrom

[root@test2 ~]# cd /mnt/cdrom/

[root@test2 cdrom]# ls

報錯：

 如果直接在掛載點目錄下解壓，會出現以下報錯：“tar: vmware-tools-distrib：無法 mkdir: 只讀文件系統”，可以將VMware Tools安裝包拷貝到其他目錄再解壓即可。

[root@test2 cdrom]# tar -zxvf /mnt/cdrom/VMwareTools-10.3.2-9925305.tar.gz

拷貝VMware Tools安裝包並解壓

[root@test2 cdrom]# cp VMwareTools-10.3.2-9925305.tar.gz /tmp/

[root@test2 cdrom]# cd /tmp/

[root@test2 tmp]# ls *.tar.gz
