一、部署準備作業
部署環境工具檢查及安裝
1）安裝epel-release庫，以防db4-devel依賴安裝失敗
1 yum -y install epel-release
2）安裝外部函式庫(libffi)
1 yum -y install libffi-devel
3）安裝編譯環境依賴(必須全部安裝成功，否則會編譯失敗)
1 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
4）安裝gcc
1 yum -y install gcc
5）安裝rz
1 yum -y install lrzsz
二、Python安裝配置作業
Python安裝及Python環境變數配置
1）rz選擇上傳python3.X的tgz安裝包
1 rz
這里選用Python3.7.1版本，上傳Python-3.7.1.tgz，
2）用tar命令解壓Python-3.7.1.tgz
1 tar -zxvf Python-3.7.1.tgz
3）切換到Python-3.7.1目錄下
1 cd Python-3.7.1
用configure將/usr/local/python3設定成安裝目錄
1 ./configure --prefix=/usr/local/python3
4）編譯安裝 make && make install(如果顯示安裝成功 就說明可以 如果提示失敗 檢查下依賴環境)
1 make && make install
5）創建Python3和pip3的軟連接
1 ln -s /usr/local/python3/bin/python3 /usr/bin/python3 2 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
6）將/usr/local/python3/bin加入PATH變數中
1 vim ~/.bash_profile
#python path
echo export PYTHON_PATH=/usr/local/python3
echo PATH=$PYTHON_PATH/bin:$PATH
修改之后source一下使變數生效，
1 source ~/.bash_profile
7）檢查Python3.7.1是否安裝好，Python2是否能運行
1 python3
1 exit() #退出Python3
1 python2
1 exit()
至此,python3安裝完成，
