python结合pyvmomi 监控esxi的磁盘等信息

1.安装python3.6.6

# 安装依赖，一定要安装，否则后面可能无法安装一些python插件
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
mkdir /usr/local/python36
tar -zxf Python-3.6.6.tgz
cd Python-3.6.6
./configure --prefix=/usr/local/python36
make && make install
ln -s /usr/local/python36/bin/python3 /usr/bin/python3
ln -s /usr/local/python36/bin/pip3 /usr/bin/pip3

# pip3 install --upgrade pip
# yum install -y git

# 安装监控vmware的sdk pyvmomi
[root@wondershareID_web03:/usr/local/python36]# git clone https://github.com/vmware/pyvmomi.git
[root@wondershareID_web03:/usr/local/python36]# cd pyvmomi/
[root@wondershareID_web03:/usr/local/python36/pyvmomi]# ls
docs  LICENSE.txt  MANIFEST.in  NOTICE.txt  pyVim  pyVmomi  README.rst  requirements.txt  sample  setup.cfg  setup.py  test-requirements.txt  tests  tox.ini
[root@wondershareID_web03:/usr/local/python36/pyvmomi]# python3 setup.py install
