Python 獲取EXSI宿主機上虛擬機器資料
阿新 • • 發佈：2020-09-23
安裝python3.6.8,依賴，一定要安裝，否則後面可能無法安裝一些python外掛
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
yum -y install python36 git
pip3 install --upgrade pip
安裝監控vmware的sdk pyvmomi
git clone https://github.com/vmware/pyvmomi.git cd pyvmomi/ python3 setup.py install
