前言
在Centos機器上安裝Python模塊 paramiko和pexpect包
以後python的模塊包都可以通過”pip install模塊名” 實現
大環境:
沒有編譯器gcc 需要安裝開發軟件
yum源沒有安裝包
系統是Centos6 需要找到合適的yum源
自帶python版本是2.6 需要升級
沒有安裝wget yum install wget 進行安裝
具體操作
1、配置yum源
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
2、安裝所有的開發工具包
yum groupinstall -y “Development tools”
3、安裝其它的
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel
安裝的python退格鍵和箭頭不可以正常使用,會出現”>>> daf ^H^[[D “這樣的怪東西。是因爲readline庫的問題。那麼解決的方法就是:
安裝yum install readline-devel.*
4、下載、編譯和安裝 Python 2.7.13
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar zxf Python-2.7.13.tgz
cd Python-2.7.13
./configure
make && make install
默認 Python 2.7.13 會安裝在 /usr/local/bin 目錄下。
ll -tr /usr/local/bin/python*
/usr/local/bin/python2.7
/usr/local/bin/python2.7-config
/usr/local/bin/python -> python2
/usr/local/bin/python2 -> python2.7
/usr/local/bin/python2-config -> python2.7-config
/usr/local/bin/python-config -> python2-config
而系統自帶的 Python 是在 /usr/bin 目錄下。
ll -tr /usr/bin/python*
/usr/bin/python2.6-config
/usr/bin/python2.6
/usr/bin/python
/usr/bin/python2 -> python
/usr/bin/python-config -> python2.6-config
更新系統默認 Python 版本
先把系統默認的舊版 Python 重命名。
mv /usr/bin/python /usr/bin/python.old
再刪除系統默認的 python-config 軟鏈接。
rm -f /usr/bin/python-config
最後創建新版本的 Python 軟鏈接。
ln -s /usr/local/bin/python /usr/bin/python
ln -s /usr/local/bin/python-config /usr/bin/python-config
ln -s /usr/local/include/python2.7/ /usr/include/python2.7
以上步驟做完以後,目錄 /usr/bin 下的 Python 應該是
ll -tr /usr/bin/python*
/usr/bin/python2.6-config
/usr/bin/python2.6
/usr/bin/python.old
/usr/bin/python2 -> python
/usr/bin/python -> /usr/local/bin/python
/usr/bin/python-config -> /usr/local/bin/python-config
查看新的 Python 版本
python –version
返回 Python 2.7.13 爲正常。
5、爲新版 Python 安裝 setuptools
爲新版 Python 安裝 setuptools
wget https://bootstrap.pypa.io/ez_setup.py -O - | python
setuptools 正確安裝完成後,easy_install 命令就會被安裝在 /usr/local/bin 目錄下了。
6、安裝pip
easy_install pip
7、安裝cryptography
pip install cryptography
8、安裝paramiko
pip install paramiko
9、安裝pexpect
pip install pexpect
10、測試,沒有報錯即可
import pexpect
import paramiko
